Description

The invention relates to a Leuchtenbaldachin for detecting and signaling different dangerous situations, the Leuchtenbaldachin is particularly useful for ceiling, pendant or pendant lights.

Heat, smoke and carbon monoxide alarms are private and commercial alarm detectors that must be installed on the ceiling in order to prevent people in the danger zone from being exposed to the danger at an early stage if a maximum temperature, smoke or carbon monoxide escapes to warn. Most smoke detectors and heat detectors are available on the market. Carbon monoxide gas warning detectors are available occasionally. Since alarms are sold on the market so far almost as a single device, three suitable for the respective hazard detection warning should be installed on the ceiling. Therefore, users, especially private individuals, refrain from using such alarms or they apply these alarms to the respective hazard detection in unsuitable locations, so that the alarm can not effectively warn of a hazard. Incorrect installation will cause the alarms to detect the danger too late or not at all. Consequently, the protection goal is not achieved, often in ignorance of the users. A central installation on the ceiling, and at best in the center of the room and the above-described subject of several devices on a ceiling reject many users due to lack of aesthetics. For this reason, lighting canopies were equipped with an integrated smoke alarm function, as for example in the DE 102 13 425 A1 or the DE 20 2010 011 744 U1 is described.

In the DE 20 2015 004 198 U1 is a light canopy with a housing part for covering electrical components described.

From the DE 20 2006 011 698 U1 a carrier element for a furnishing and / or decorative item is known, wherein the carrier element has a receiving area in which a smoke detector can be arranged.

It is also known to screw a Lampenbaldachin to a smoke or fire alarm, dock or glue, as for example in DE 20 2011 106 446 U1 is described.

From the EP 2 700 874 A1 a luminaire suspension with a housing is known in which, inter alia, a camera, a power supply and a processor and storage unit can be arranged.

The WO 2016/183 354 A1 describes a connection of power supply, electrical support and sensor element, which can be arranged in a light canopy.

The invention has for its object to further develop the known lampposts to the effect that several dangerous situations can be detected and signaled in a space-saving, cost-effective and reliable manner.

The above technical problem is solved by the features of claim 1.

Thereafter, a light canopy for detecting and signaling different dangerous situations is provided, especially in rooms or buildings, the light canopy is particularly useful for a ceiling pendant or pendant lamp.

The illuminated canopy has a cover cap with a passage opening for passing through an electrical cable, in particular for a ceiling pendant or suspended luminaire. The cap can be made of plastic and / or metal. Furthermore, a partition wall is provided which divides the cap into a first receiving area and into a second receiving area. The passage opening is arranged in the first receiving area, preferably centrally in the bottom area of the cover cap. The second receiving area forms in the mounted state, a chamber on all sides. The partition may be made of plastic and / or metal, for example. For example, the cap can also be produced by a plastic injection molding process.

Further, a cover is provided, which covers the second receiving area, so that in the assembled state of the light canopy in the all-round-walled chamber. The partition and the cover are integrally formed or glued together.

To ensure that the second receiving area is not accessible from the outside, the dividing wall and the cover are potted with the covering cap. In this way, the second receiving area can not be opened without destroying the light canopy. This ensures that a proper operation of the devices for detecting and signaling a dangerous situation can be ensured.

Furthermore, at least two different, independently operable devices for detecting and signaling a dangerous situation are provided, wherein the one device for the detection and signaling of a first dangerous situation and the other device of the at least two devices for detecting and signaling a second dangerous situation different from the first dangerous situation is formed, wherein the energy supply of the at least two means for detecting and signaling a dangerous situation is in each case with a separate battery, wherein the at least two means for detecting and signaling a dangerous situation and the batteries in the second receiving area of the cap are arranged.

Thanks to this measure, at least two different devices for detecting and signaling different dangerous situations can be implemented completely and in the smallest space in a defined subregion of the cap of the light canopy.

The integration of devices for detecting and signaling different dangerous situations in a light canopy, no installation errors arise because the canopy is necessarily attached to the ceiling and usually centrally. Aesthetic disadvantages of the previously described disadvantages with several individual alarms on the ceiling remain.

The expression "operable independently of one another" is intended in particular to express that the at least two different devices for detecting and signaling a dangerous situation can independently detect and signal different dangerous situations. In particular, the at least two means for detecting and signaling a dangerous situation are galvanically isolated from each other and they are independently supplied with energy.

Due to the fact that the second receiving region of the cap of the light canopy forms a chamber which is surrounded on all sides, the devices for detecting and signaling a hazardous situation are not accessible from the outside.

According to an advantageous development, the second receiving area formed in the mounted state as a closed chamber on all sides can not be opened without damage.

Advantageously, the at least two devices for detecting and signaling a dangerous situation each have an evaluation and control device, a detector device, at least one optical signal transmitter, an acoustic signal transmitter and a test button.

In addition, in the second receiving area first recesses for receiving the test button, second recesses for receiving the optical signal transmitter and third recesses for receiving the acoustic signal generator may be given. The first and / or second and / or third recesses may be covered by gas-permeable perforated grids, which prevent penetration of micro-insects and flies, in particular into the second receiving area. The perforations of the perforated grille, for example, have a maximum diameter of 1mm.

The at least two devices for detecting and signaling a dangerous situation can be checked independently of one another via the test buttons that can be actuated from the outside.

The optical signal transmitters can be designed, for example, as LEDs. The test buttons are arranged in such a way that when the button is pressed, the visual signal is recognizable and not covered by the finger.

According to an advantageous embodiment, the optical signal transmitters and the test probes can be mounted on a first printed circuit board, wherein the evaluation and control devices, the batteries and the detector devices can be mounted on a second printed circuit board. Both printed circuit boards are arranged in the second receiving region of the cap.

Conveniently, the partition and the cover can be permanently connected to each other.

Partition and cover can each be made of plastic and / or metal.

It should be noted at this point that, alternatively, the partition is also produced in one piece with the cap, for example by a plastic injection molding process.

Preferably, the second receiving area, which forms a chamber which is surrounded on all sides, is formed in sections, that is to say preferably in a gas-permeable manner at several points. This is particularly necessary when the one device for detecting and signaling smoke and the other device for detecting and signaling carbon monoxide is formed.

A partially gas-permeable second receiving area is obtained if, for example, the dividing wall is designed as a gas-permeable perforated grid. Conveniently, the perforations of the perforated grid wall have a maximum diameter of 1mm.

Alternatively or additionally, a plurality of openings or recesses may be provided in the cover cap or the cover, which are covered for example by means of a perforated grid from the outside or the inside of the cap to make the second receiving area partially permeable to gas.

Advantageously, the one device for detecting and signaling smoke, or carbon monoxide or heat as the first hazardous situation and the other device of the at least two devices for detecting and signaling smoke, or carbon monoxide or heat as the second danger situation different from the first dangerous situation formed.

Due to a common public inadequacy that carbon monoxide is heavier than air and therefore in practice often provided for this purpose warning detectors are installed on the ground and therefore useless, the integration of a device for detecting and signaling carbon monoxide in a light canopy is optimal because the carbon monoxide gas is lighter than air and rises up towards the ceiling and therefore optimally detected in the Leuchtenbaldachin, which is installed centrally on the ceiling. Also in relation to smoke detectors such devices are installed in or on cabinets, within door frames or walls in practice and detect their intended risk far too late or not at all. Since the early detection of smoke and fire and the associated alerting of the persons at risk are elementary for saving lives and lives, there is a danger to the lives of the aforementioned installation errors. Since the light canopy invention is expediently installed centrally on the ceiling, it represents an optimal early detection of the physical hazards smoke, carbon monoxide gas and heat.

In order to be able to set up a communicating system of devices disposed to each other for detecting and signaling a dangerous situation, a transmitting device assigned to the evaluation and control devices can be arranged in the second receiving area, which can be used for wireless and / or wired transmission of a state signal of the at least two devices Detecting and signaling a dangerous situation to at least one remote device for detecting and signaling a dangerous situation is formed. Additionally or alternatively, in the second receiving area, a receiving device associated with the evaluation and control device can be arranged, which is designed to receive a status signal from at least one remote device for detecting and signaling a dangerous situation for wireless and / or wired reception.

1 shows in a perspective view of an exemplary Leuchtenbaldachin 10 in which a plurality of different and independently operable devices for detecting and signaling different dangerous situations are integrated, as for example in 4 is shown schematically. In the following, the devices for detecting and signaling a dangerous situation are also colloquially referred to as warning alarms.

The light canopy 10 has a cap 70 on, for example, has a frusto-conical contour. However, covers with other contours can also be used. The cap 70 is with a through hole 20 provided for performing a supply line for a luminaire, which can be electrically connected to a led out of a ceiling power line.

The cap 70 has a circular bottom in the example shown 71 on, in which the passage opening 20 is provided. Preferably, the floor can 71 a cable feedthrough and fixation nozzle 21 have, by the passage opening 20 is trained. In the cable bushing and fixation pipe 21 can be a locking screw 22 be used. Once the power line is connected to the lamp supply, the Leuchentbaldachin can 10 vertically along the lamp feed line towards the ceiling 120 moved and with the locking screw 22 be fixed. The supply line and power line then disappear in the light canopy 10 , as in 4 is shown.

Preferably in the ground 71 At least two recesses may be provided for optical signal transmitter different warning. In the example shown is a circular recess 30 for an optical signal transmitter 136 a facility 130 for detecting and signaling smoke, in short called smoke detectors, a circular recess 31 for an optical signal transmitter 146 a facility 140 for detecting and signaling heat or heat, heat detector for short, and another circular recess 32 for an optical signal transmitter 156 a facility 150 for detecting and signaling carbon monoxide, called carbon monoxide detector for short, provided. LEDs can be used as optical signal transmitters. By means of the optical signal transmitter 136 . 146 and 156 For example, the operating state of the respective warning signal can be signaled. There may be further recesses provided for further optical signal transmitter of the respective alarm, which then signal, for example, the state of charge of a battery.

In the ground 71 At least two further recesses are provided with test probes of different warning detectors. In the illustrated embodiment, a recess 40 for a test button 135 of the smoke detector 130 , a recess 41 for a test button 145 of the heat detector 140 and a recess 42 for a test button 155 the carbon monoxide detector 150 intended. By means of externally operable test buttons, the functionality of the respective alarm can be checked.

It should be noted that the recesses 30 to 32 and 40 to 42 in one area of the ground 71 are excluded, leading to a second reception area 81 the cap 70 heard, for example, in 2 is shown and in which the alarm 130 . 140 and 150 are arranged as shown schematically in 3 is shown. It should also be noted that the recesses 30 to 32 and 40 to 42 in each case by a on the inside or outside of the cap 70 may be covered mounted perforated grid, whose perforations are sized so that small insects and flies are not in the second receiving area 81 can penetrate.

The cap 70 For example, has a frustoconical jacket 72 on, for example, in which several recesses 60 , preferably circular recesses are provided which are permeable, for example, for smoke and carbon monoxide, but not for micro-insects or flies. For this purpose, the recesses 60 for example, on the inside of the jacket 72 with lattice-like covers 110 be covered, as for example in the 1 to 3 is shown. The diameter of the holes is preferably no greater than 1mm. The recesses 60 can over the entire circumference of the cap 70 be distributed.

In the exemplary frustoconical jacket 72 the cap 70 At least two further recesses may be provided for receiving in each case an acoustic signal transmitter of a respective warning detector. In the example shown is a recess 50 for an acoustic signal generator 134 of the smoke detector 130 , a recess 51 for an acoustic signal generator 144 of the heat detector 140 and a third recess 52 for an acoustic signal generator 154 the carbon monoxide detector 150 intended. The respective acoustic signal transmitters can extend at least partially into the recesses, which in turn can be covered by perforated grids which prevent the penetration of micro-insects and flies. The acoustic signal transmitters can be designed as piezoelectric elements, which can generate, for example, in each case a volume of 85 dBA.

The light canopy 10 has a partition 90 on which the cap 70 in a first reception area 80 and in the second recording area 81 divided as in 2 is shown by way of example. The partition 90 has according to the exemplary frustoconical contour of the cap 70 a cone-shaped extending cross-section, wherein in the assembled state of the ground 71 and the coat 72 the cap 70 flush with the partition 90 are connected, so that at least small insects and flies are not in the second receiving area 81 can penetrate.

In the ground 71 and in the coat 72 can grooves for receiving and fixing the partition 90 be provided. ground 71 and partition 90 are essentially perpendicular to each other. Preferably, the partition is a perforated grid partition whose holes have a maximum diameter of 1mm.

As in 2 to see is the passage opening 20 for passing an electrical cable in the first receiving area 80 arranged. The second recording area 81 forms in the mounted state, a chamber on all sides, as in, for example, in 3 is shown.

The first recording area 80 is on the other hand to the ceiling 120 opened, and forms a sufficiently large space, in the assembled state, the coming out of the ceiling power line and the electrical connection point at which the power line is connected to the lamp supply to cover. The first recording area 80 thus acts as a conventional light canopy.

3 shows how 2 a plan view of the cap 70 of the light canopy 10 , 3 clearly shows the recesses 60 and the hole grid-like covers shown schematically 110 which the recesses 60 cover so that they are only gas permeable.

3 continues to show a cover 100 with which the second recording area 81 is covered. In the assembled state forms the second receiving area 81 thus a chamber closed on all sides, which is permeable to gas but not to micro-insects and flies. In the embodiment shown, the cover 100 a circular segment-shaped cross section. In particular, the chamber, which is surrounded on all sides, is replaced by a section of the floor 71 through a section of the mantle 72 through the partition 90 and the cover 100 is formed.

partition wall 90 and cover 100 are preferably permanently connected. This can be realized by the fact that the partition 90 and the cover 100 can be integrally formed or glued together as separate elements. To make sure the second recording area 81 for a person is not accessible from the outside, the dividing wall can 90 and the cover 100 with the cap 70 to be shed. Preferably, the second receiving area 81 without damaging the cap 70 or the light canopy 10 not be opened. In this way it can be ensured that the integrated in the second receiving area alarms can always work properly.

In the 2 and 3 is also the passage opening 20 to see through which a guided out of a ceiling power line can be performed. Conveniently, like the 1 to 3 show the passage opening 20 in the middle of the floor 71 and in the first recording area 80 arranged so that a power line perpendicular to the passage opening 20 can be introduced. In this way, the Leuchtenbaldachin 10 For example, after connecting a lamp vertically upwards towards the ceiling 120 pushed and through the locking screw 22 be attached to the power line. This mounting state is, for example, in the schematic representation according to 4 to see in the schematic, a side view of the Leuchtenbaldachins 10 with opened second recording area 81 is shown.

As already mentioned and in 4 are shown in the second receiving area 81 of the light canopy 10 arranged at least two different, independently operable alarm, wherein the power supply of at least two alarms each with a separate battery. The at least two alarms and the batteries are in the second receiving area 81 the cap 70 arranged. In the example in 4 shown embodiment are three different, independently operable alarm, namely the smoke detector 130 , the heat detector 140 and the carbon monoxide detector 150 in the second recording area 81 arranged.

The smoke detector 130 is powered by its own battery 131 supplies and also has an evaluation and control device 132 , a measuring chamber 133 , the sounder 134 , the test button 135 as well as the optical signal transmitter 136 on, all electrically with the evaluation and control device 132 are connected. The evaluation and control device 132 For example, it is designed to be the acoustic signal transmitter 134 and / or the optical signal transmitter 136 to activate when the state of charge of the battery 131 has reached a critical value, the battery life has expired and / or the measuring chamber 133 reports a critical smoke development. The battery 131 is preferably with all components of the smoke detector 130 electrically connected.

Like the smoke detector 130 has the heat detector 140 its own separate battery 141 , an evaluation and control device 142 , a thermal sensor 143 , the sounder 144 , the test button 145 and the optical signal transmitter 146 All of them with the evaluation and control device 142 are connected. The evaluation and control device 132 For example, it is designed to be the acoustic signal transmitter 144 and / or the optical signal transmitter 146 to activate when the state of charge of the battery 141 has reached a critical value, the battery life has expired and / or thermal sensor 143 a critical temperature (typically 60 ° Celsius) reports. Alternatively or additionally, with the aid of the evaluation and control device 142 a temperature differential method are carried out with which a temperature increase is evaluated within a defined time with respect to an actual existing or emerging brand. The battery 141 is preferably with all components of the heat detector 140 electrically connected.

The carbon monoxide detector 150 again has its own separate battery 151 and an evaluation and control device 152 , a carbon monoxide sensor 153 , the sounder 154 , the test button 155 and the optical signal transmitter 156 All of them with the evaluation and control device 152 are connected. The Evaluation and control device 152 For example, it is designed to be the acoustic signal transmitter 154 and / or the optical signal transmitter 156 to activate when the state of charge of the battery 151 has reached a critical value, the battery life has expired and / or the carbon monoxide sensor 153 reports a critical carbon monoxide gas rise. The battery 141 is preferably with all components of the carbon monoxide detector 150 electrically connected. Due to a common misconception that carbon monoxide is heavier than air, in practice carbon monoxide detectors are installed on the ground where they are useless. Therefore, the integration of means for detecting and signaling carbon monoxide gas in a ceiling mountable light canopy is optimal.

It should also be noted that the evaluation and control devices can each have a microprocessor or microcontroller.

In this way, three independently operable, galvanically separated devices for detecting and signaling each an individual hazardous situation in the second receiving area 181 the shining canopy 10 integrated. The batteries 131 . 141 and 151 are permanently connected to the smoke detector, the heat detector or the carbon monoxide detector and usually have a service life of 10 years.

On the circuit board 160 can the test button 135 and the optical signal transmitter 136 the smoke detector, the test button 145 and the optical signal transmitter 146 of the heat detector 140 as well as the test button 155 and the optical signal transmitter 156 the carbon monoxide detector 150 be mounted. The circuit board 160 is arranged such that the test button 135 . 145 . 155 in alignment with the recesses 40 to 42 and the optical signalers 136 . 146 and 156 in alignment with the recesses 30 to 32 are aligned. The optical signal transmitters and the test probes can at least partially into the corresponding recesses 30 to 32 respectively. 40 to 42 protrude.

As in 5 is exemplified, the batteries 131 . 141 and 151 , the evaluation and control equipment 132 . 142 and 152 as well as the measuring chamber 133 , the heat sensor 143 and the carbon monoxide sensor 153 on a second circuit board 170 be arranged. For example, lead three tracks of the evaluation and control device 132 of the smoke detector 130 to three electrical connections 180 . 181 and 182 , which may preferably be formed as connection pads on the second circuit board. To the electrical connection 180 can the acoustic signal generator 134 of the smoke detector 130 be connected. The electrical connections 181 and 182 can each have an electrical cable with an electrical connection 190 respectively. 191 on the first circuit board 160 be connected so that the acoustic signaler 134 , the test button 135 and the optical signal transmitter 136 the smoke detector with the evaluation and control device 132 are connected.

In this way, the test button 145 and the optical signal transmitter 146 with the evaluation and control device 142 of the heat detector 140 get connected. For this purpose, the connection pad 192 over a trace with the test button 145 be connected while the connection pad 193 via a separate trace with the optical signal transmitter 146 can be connected. About not shown traces and / or electrical cables, the battery 141 electrically with the test button 145 , the optical signal transmitter 146 and the acoustic signal transmitter 144 be connected.

Similarly, run by the evaluation and control device 152 the carbon monoxide detector 150 three tracks to three other electrical connections 186 . 187 and 188 , To the electrical connection 188 can the acoustic signal generator 154 be connected while the electrical connections 186 and 187 each via an electrical cable with an electrical connection 194 respectively. 195 on the first circuit board 160 can be connected. In this way, the test button 155 and the optical signal transmitter 156 with the evaluation and control device 152 get connected. For this purpose, the connection pad 194 over a trace with the test button 155 be connected while the connection pad 195 via a separate trace with the optical signal transmitter 156 can be connected. About not shown traces and / or electrical cables, the battery 151 electrically with the test button 155 , the optical signal transmitter 156 and the acoustic signal transmitter 154 be connected.

The second circuit board 170 can, for example, via appropriate mounting elements with the partition 90 get connected. It is also conceivable that the second circuit board 170 directly on the cap 70 within the second recording area 81 is attached. partition wall 90 and circuit board 170 are preferably arranged parallel to one another, as shown in FIG 4 is indicated.

In the second recording area 81 may be a wireless and / or wired transmitting and / or receiving device 200 be arranged on the status signals of the three alarms 130 . 140 and 150 can be transmitted to external alarms and / or status signals can be received from external alarms. The received status signals can then be sent to the respective evaluation and control devices 132 . 142 and 152 forwarded for further processing.

Conveniently, the transmitting and / or receiving device 200 also on the second circuit board 170 mounted and with the respective evaluation and control devices 132 . 142 and 152 electrically connected. It should also be noted that the transmitting and / or receiving device 200 even with the one from the ceiling 120 led out power cable can be connected for communication with external alarms.

Thanks to the structure according to the invention can in the Leuchtenbaldachin 10 at least two, preferably three different facilities 130 . 140 and 150 be integrated for detecting and signaling hazardous situations, so that different hazardous situations, namely smoke, carbon monoxide gas leakage and critical room heating can be detected and signaled independently. The reliability of the alarm functions is increased by the fact that each alarm detector has its own battery, its own evaluation and control device, its own detector device, its own test button, its own acoustic signal generator and at least its own optical signal generator.
