Below the detailed description about light fixture of the present invention be based on that the accompanying drawing of preferred embodiment carries out, purpose is in order to understand the present invention better, but should not be interpreted into restrictive because this design details can be applicable to different demands easily.
The corresponding world standard of the base that in example, is adopted/jack system symbol G5 and G13 system, but can not be construed to restrictive requirement.Opposite, this is to use system the most widely.Base/jack system G5 is in particular new high-performance 16mm diameter fluorescent lamp design.Therefore, in description with reference to this system.The present invention can be used for any other base/jack system in essence, even following base/jack system is no exception.
In all are described, be identical to the reference numerals of same parts.
The two-wire of drawing in Fig. 4 at Fig. 1 has clearly illustrated that especially and has disposed the very big simplicity that reflecting element forms the modulation element (30) of hollow bulb, this hollow bulb can be used for holding simultaneously electric ballast, and only being equipped with two transverse planes (2) at the two ends of reflectoscope is used for supporting socket (9).Socket (9) is suitable for clamping fluorescent tube (14) and for it provides power supply, and its mode is that each end at fluorescent tube (14) adopts a pair of traditional tower bolt (13a).
Modulation element (30) only comprises two basic parts, the hollow bulb that promptly stretches out (1) and two identical transverse planes (2), and the latter can be assembled to the two ends of lamp.Modulation element (30) comprises the circuit board (3) that has eight identical elastomeric spring contacts (8), and these contacts are welded direct on the circuit board (3), is actually the electronic component of ballast.The modulation element rest parts is some findings, such as, line voltage connector, these can be selected from a large amount of standard finished products parts.
Hollow bulb (1) as shown in Figure 4, the also subsidiary transparent cover (11) that can insert groove (22) that shown among this figure, for the reason of ventilating, this is sealed on not sealing of two ends.
Fig. 4 a is depicted as the modification that only is suitable for narrow circuit plate (3), has on the hollow bulb (1) to strengthen with midfeather (19).Adopt such enhancement measures in the parts of plastics suggestion of stretching out, thereby because can reduce the thickness economical with materials of wall this moment.Naturally, same measure also is applicable to the part of pulling out of using aluminium or other materials.
Fig. 1 has also shown the simplicity that the present invention installs, and is positioned at guided plate (4) the upper spring joint (5) of transverse plane (2) such as use.Only need simply transverse plane (2) to be pushed into hollow bulb (1) in spring joint (5) is pressed into the recess (6) of hollow bulb (1).Be welded to spring contact (8) on the circuit board (3) in advance and be pressed into socket (9) under shed, circuit board (3) is pierced in the guide-track groove (7) with that, and soft copy is installed and just finished like this.Owing to need to be connected to line voltage in many cases, such as in the U.S., loose electric wire is welded direct on the circuit board (3), so described this jointing herein especially.The standard plug connection or the joint that are applicable to this circuit board (3) have much available.

The light fixture of common band inductive ballasts can not be assembled into high performance Fluorescent lamp.The T5 light fixture needs electric ballast, and has the G5 plug housing, and span is also different between its latch.
Because design length only is the length issue of hollow bulb (1), so the line of cut (20) that draws in Fig. 1 and Fig. 2 is emphasized this point.
Fig. 3 part in proportion shows how to place some relatively heavier electronic devices, and such as the induction coil of transformer (15) or equivalence design, these electronic devices can be placed in the hollow bulb (1) below the reflecting element.The unemployed part of hollow bulb can be designed to compact form.
Another kind of modification of the present invention is the half lamp device (40) of Fig. 5 to the band fluorescent lamp (14) of Figure 10 description.Half lamp device (40) is suitable for existing light fixture (still being equipped with out-of-date inductive ballasts) is converted to obviously superior velocitron.
It is exactly to serve for this purpose that the transverse plane (2) of device (40) is gone up the plug housing (10) that is provided with.Plug housing (10) has a pair of modulation element latch (13), and therefore its corresponding standard G13 base/jack system can be inserted on the light fixture of present visible any kind of.Described embodiment supposes that the user is also ready to utilize many advantages of the new fluorescent tube of T5.Therefore, plug housing (10) has the latch (13) that socket (9) towards inside adapts to T5 fluorescent tube (14).Following description is applicable to half lamp of the double fluorescent lamp (14) with corresponding diagram 1 to Fig. 4 naturally, and vice versa.
Half lamp of light fixture occurs when being used for improved, but does not have the Compact Design of hollow bulb (1).Corresponding half lamp of the present invention is characterised in that: the plug housing that is assembled (10) can rotate about an angle of 90 degrees in sleeve pipe (18).Like this, half lamp just can be inserted into existing socket (9) and distortion that need not be complicated, and by rotation plug housing (10), half lamp can be locked in the socket of existing light fixture.
Fig. 5 shows the side view of half lamp of band hollow bulb (1), and this hollow bulb is mentioned top all details, such as surface-mounted integrated circuit (3), and guided plate (4), spring joint (5) or the like can unrestrictedly be used.Different is the design of plug housing (10), rotatably is assemblied in the sleeve pipe (18).
Fig. 8 display end plane is inserted into the view before the existing light fixture.Element (30) has a pair of lamp latch (13), and its direction is towards the direction of inserting lamp device, and according to half lamp in the direction locking light fixture of arrow (21), this light fixture is retrofited with rotatable plug housing (10).Can rotate plug housing (10) easily, such as the handle (12) that use is stretched out, this handle appears at the position shown in the dotted line after rotation.
The particular design shape on Fig. 9 display end plane (2) is so that can use simple mould to produce.In this case, socket (9) is designed to from rotatable plug housing (10) side openings, and the connecting line of (13) can enter or draw easily from the soft copy to the latch like this.Because the rotatable plug housing of insertion (10) this opening afterwards just has been capped, therefore, do not need additional capping to protect the spring contact (8) of conduction.
Rotatable plug housing (10) can be equipped with halt and limit in a known manner to rotatablely move and be connected with joint.
Figure 10 is half a lamp profile through the A-A line, and this figure shows, even width is limited, also has enough spaces to be used for placing electronic component.Below circuit board (3), can find enough spaces to place SMD element (16) so that make the size of circuit board (3) keep very little.
In a word, corresponding Design of Luminaires at shielded stable hollow bulb of the present invention provides significant superiority.Number of spare parts in this light fixture is reduced to minimum.Material that is consumed and working cost are not only cost advantage, and mean the burden (by lower energy resource consumption) that has lowered environment.
Compared with former method (assembling the light fixture of independent ballast), at the shell of complexity It almost is impossible using joint and connecting line to install and assemble them in the body, also is unnecessary . Corresponding cost-effective Novel compact light fixture of the present invention is conducive to advance use energy-conservation Lamp, and the new space of developing profit.
