Abstract

The utility model discloses an emergency light for instructions. An EL luminescent screen, storage batteries and a circuit board are arranged in a light shell. A spontaneous screen is attached to the EL luminescent screen. The utility model has the advantages of compact structure, clear radiation, soft color, no killo, strong penetrating power of smog, etc. Compared with the similar products with other light sources, the utility model also has the advantages of high pressure withstanding performance, low power consumption and long service life. When a main power(or an emergency power) is on, the spontaneous screen lumines together with the EL luminescent screen; and when no power supply is available, the emergency light works depending on the spontaneous screen can work more than 12 hours.

Description

A kind of novel emergency indicator light

The utility model relates to a kind of non-lamp for general lighting, specifically a kind of emergency lamp that is used to indicate.

Existing emergent indicator light is aspect light source, and a class is to adopt fluorescent lamp as light source, and another kind of is to adopt the EL electroluminescent panel to make light source.The brightness that fluorescent lamp generally just can be up to state standards and require at 20-30W, EL electroluminescent panel then power consumption 2-5W just can be up to standard.The EL electroluminescent panel is a kind of novel film cold light source, and it is to produce electric field by the voltage that is added on the electrode, is caused that by electric field electrons excited percussion luminescence center the transition of the electronic energy utmost point causes luminous a kind of physical phenomenon with changing compound.The emergent indicator light that comprises this light source is that EL electroluminescent panel, storage battery and circuit board are housed in lamp housing.When energized, mains lighting supply is given the power supply of EL electroluminescent panel through electronic transformer and rectification circuit, is charge in batteries simultaneously; After power supply was cut off, storage battery in time was the luminescent screen power supply after inversion, and it is luminous that the EL electroluminescent panel is continued, and for people indicate a mouthful passage, realizes emergent indication.No matter be which kind of emergent indicator light, the operating time of its emergent indication all is to decide by the operating time of storage battery at present.Existing national Specification: the emergency time of fire emergency lamps should be not less than 90 minutes.The emergency time of existing emergent indicator light generally can reach about 2 hours, though this provides the necessary time for escape personnel and rescue worker, but because fire takes place and the length of the time of putting out a fire to save life and property is difficult to estimate, and the fire of building and the time of putting out a fire to save life and property often reach 6-10 hour even longer, 2 hours emergency times of so existing emergent indicator light are just very inadequate, and this rescue operation for the rescue personnel is very disadvantageous.And prolong emergency time of indicator light by the operating time of improving storage battery, then the cost that is increased is huge, and technical obstacle is also a lot, thereby is not suitable for practicality.

The purpose of this utility model just provides a kind of low, emergent fluorescent lifetime that consumes energy and is longer than the novel emergency indicator light that national standard requires, and thinks that personnel escape and fire fighter's rescue operation provides great help.

The purpose of this utility model is achieved in that EL electroluminescent panel, storage battery and circuit board still is housed that institute's improvements are to be pasted with spontaneous optical screen on the EL electroluminescent panel in lamp housing.Spontaneous optical screen is as self-luminous body with the overlength afterglow luminescent material, the light of the etalon optical power illumination that absorb, the emergent original luminous element of indicator light of storage is provided, after original luminous element quits work, still can realize the long-time continued luminous of self, and luminosity complies with the national standard requirements.

Though the used spontaneous optical screen of the design utilizes the illumination of various visible lights (as daylight, light or natural daylight etc.) can be luminous, but in order to realize the optimal luminescent effect, itself and EL electroluminescent panel are combined closely, make it directly to absorb the light that is sent from the EL electroluminescent panel.Because the extinction distance is nearly (several microns) very, so just can guarantee that spontaneous optical screen can absorb the light source of enough light intensity, and hold long enough between the light time.Itself is very strict because the sign of EL electroluminescent material is luminous, and therefore the extinction of the spontaneous optical screen that attaches with it is just very even, and the light that it sent is also just more evenly long-acting.When main power source (or emergency power supply) was powered, spontaneous optical screen was luminous with the EL electroluminescent panel; When non-transformer, be after tested: be not less than 3cd/m with white or green combination or white and the red figure that constitutes, the surperficial minimum brightness of indicator light that literal is sign by the emergent indicator light luminosity of spontaneous optical screen work ², high-high brightness is not more than 300cd/m ²White, green or red maximum ratio with minimum brightness own are not more than 10, the ratio of the brightness of white and adjacent green, both sides, red boundary corresponding points is not less than 5 and be not more than 15, meet the requirements fully, and the emergency time of emergent indicator light is greater than 12 hours.

The utlity model has characteristics such as compact conformation, luminous clear, photochromic soft, no blackspot, smog penetration power be strong, than the like product of other light sources, withstand voltage height, low in energy consumption, the life-span is long.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is product appearance figure of the present utility model.

Fig. 2 is a cross-section cutaway view of the present utility model.

Fig. 3 is the partial enlarged drawing of Fig. 2.

Fig. 4 is the cross-section cutaway view of spontaneous optical screen.

As shown in Figure 1, external structure that should anxious indicator light is basic identical with the structure of existing indicator light, and wherein 1 be lamp housing, and 2 is luminescent screen, and 3 is suspension ring, and 4 is line outlet, and 5 is to lead electric, fault and charging indicator light, and 6 is sense switch.

Among Fig. 2, luminescent screen 2 is positioned at the front of lamp housing 1, and storage battery 11 and circuit board 10 are positioned at the back of lamp housing 1.Luminescent screen 2 (as shown in Figure 3) closely is attached to together by glass or polymethyl methacrylate 7, spontaneous optical screen 8 and EL electroluminescent panel 9 to be formed.Wherein spontaneous optical screen 8 is to be printed with self-luminous bisque 13 on transparent dielectric layer 14 as shown in Figure 4, and transparent protective film 12 covers outside the self-luminous bisque 13.Transparent dielectric layer 14 can be a kind of in glass, polymethyl methacrylate, VC film, VC plate, PVC film or the PVC plate.Self-luminous bisque 13 is with commercially available overlength afterglow luminescent material (SrO.nSiO ₂MAl ₂O ₃: Eu Dy), is printed on it on transparent dielectric layer 14 by silk screen printing.The effect of transparent protective film 12 is to prevent the direct erosion to self-luminous bisque 13 such as airborne moisture, dust and acid, alkali, and injury that the self-luminous bisque is caused such as the bump that can prevent from simultaneously to collide with, to prolong the luminous useful life of product.The back side at transparent dielectric layer 14 also can be covered with layer of transparent diaphragm 15, so that spontaneous optical screen 8 is played the better protection effect.
