Description

A kind of LED module is as the light fixture of automobile lamp light source

Technical field

The utility model belongs to the automobile lamp lighting field.Especially relate to a kind of automobile lamp that is contained in certain particular space and needs to reach the LED module of certain certain effects after being lit.

Background technology

At illuminating industries such as automobile lamps, led light source has obtained using more and more widely now, and its appearance effect demand emerges in an endless stream, thereby different shape, structure and the fixed forms of LED module also arisen at the historic moment.

For the fixed plate of LED particle in the LED module, generally be divided into hard substrate, die-stamped circuit plate, soft base plate, it is mixed sometimes also to have two kinds of sheet materials, middle with wire or hard pin connection.Wherein hard substrate pattern is simple, manufacturing price is low, be applicable to the horizontal layout of LED particle, soft base plate generally need to have skeleton to support, pattern is complicated, manufacturing price is higher, and the solid space that is applicable to the LED particle arranges, and the mixed plate that connects with wire or hard pin, its poor reliability is only used in the situation of some special requirements.The LED particle is spot light, and needs the area source effect during design of some car lights.Solid how to use simple hard substrate to reach the LED particle is arranged how to make LED become area source by spot light, is the theme that the utility model proposes.

Summary of the invention

Be spot light in order to make the LED particle, when some car light design, need the area source effect, the purpose of this utility model is to provide the light fixture of a kind of LED module as the automobile lamp area source, to have used a kind of mode of erectting installation to fix the hard substrate module of LED, make the LED particle in perpendicular all around direction arrange, reach and be similar to three-dimensional effect of arranging; Be fixed in upper side wall outside or the lower wall outside of reflective surface, reached the effect of hiding.

The technical solution of the utility model is achieved in the following ways: a kind of LED module is as the light fixture of automobile lamp light source, comprise speculum and LED module, the LED module is assemblied in the outer surface of the reflective surface sidewall of speculum, the hard substrate two sides of LED module are respectively equipped with narrow groove and wide groove, narrow groove is stuck on the rib of mirror back surface, rib on the speculum also is groove structure, limits up and down play of hard substrate; The another side of hard substrate is pressed on the wide groove with plastic spacer, plastic spacer by tapping screw by with speculum on screw hole screw and be fastened on the speculum front and back play of the hard substrate of rib engagement limits on plastic spacer and the speculum after cooperating.

The upper side wall of described reflective surface has square breach, and the LED particle was positioned at the party's v notch v after the LED module was assembled on the speculum.

Described speculum 1 is provided with four equidistant ribs, and the front of speculum is comprised of a plurality of paraboloid structures, is provided with the LED particle between its parabola.

The utility model, the hard substrate module of the LED of use only is subjected to force direction to use screw to fix at 1, and other directions provide spacing by the limit ribs on the speculum, and perhaps the plastic spacer by abnormal shape provides fixing; Tapping screw hole on the speculum is consistent with speculum master stripping direction with limit ribs, and mould structure is simple.Because the hard substrate module of LED is fixed in upper side wall outside or the lower wall outside of reflective surface, so that the LED particle can be distributed on the focus of reflective surface, has lighted whole reflective surface, has utilized more efficiently reflective surface, makes spot light become area source.

Among the figure: 1 speculum, 2 LED modules, 3 plastic spacers, 4 tapping screws, 5 reflective surfaces, 11 ribs, 21 hard substrates, 211 narrow grooves, 212 wide grooves, 13 breach, 14 screw holes, 22 LED particles.

The specific embodiment

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

As shown in Figure 1, be the utility model perspective exploded view.The part that relates to comprises speculum 1, LED module 2, plastic spacer 3 and tapping screw 4, the LED module is assemblied in the outer surface of the reflective surface sidewall of speculum 1, hard substrate 21 two sides of LED module are respectively equipped with narrow groove 211 and wide groove 212, narrow groove 211 is stuck on the rib 12 at speculum 1 back side, limit hard substrate left and right sides play, rib 12 on the speculum also is groove structure, limits up and down play of hard substrate; The another side of hard substrate is pressed on the wide groove 212 with plastic spacer 3, plastic spacer by tapping screw 4 by with speculum on screw hole 14 screw and be fastened on the speculum 1 the front and back play of the hard substrate of rib 12 engagement limits on plastic spacer 3 and the speculum after cooperating.

Being known by Fig. 2, is rearview of the present utility model.Hard substrate 21 two sides of LED module 2 are respectively equipped with narrow groove 211 and wide groove 212, and narrow groove 211 is stuck on the rib 12 at speculum 1 back side, limit hard substrate 21 left and right sides plaies.

Being known by Fig. 3, is the left view of Fig. 1.It is groove structures that speculum 1 is provided with four equidistant ribs 12, ribs 12, speculum 1 the front formed by a plurality of paraboloid structures, be provided with LED particle 22 between its parabola, plastic spacer 3 by tapping screw 4 by with speculum on screw hole 14 screw and be fastened on the speculum 1 after cooperating.

Being known by Fig. 4, is front view of the present utility model.LED module 2 is assemblied on the outer surface of upper side wall in reflective surface 11 radial decorative pattern zones 14 of speculum.

Being known by Fig. 5, is the partial enlarged drawing of Fig. 2.Hard substrate 21 two sides of LED module 2 are provided with groove, narrow groove 211 is stuck on the rib 12 of mirror back surface during assembling, limit hard substrate left and right sides play, narrow groove 211 is stuck on the rib 12 at speculum 1 back side, limit hard substrate 21 left and right sides plaies, and the another side of hard substrate 21 is pressed on the wide groove 212 with plastic spacer 3, plastic spacer 3 by tapping screw 4 by with speculum on screw hole 14 screw to cooperate and be fastened on the speculum front and back play of the hard substrate of rib 12 engagement limits on plastic spacer 3 and the speculum.

Being known by Fig. 6, is the A-A profile of Fig. 5.The upper side wall of reflective surface has square breach 13 in the speculum 1, and after LED module 2 was assembled on the speculum, LED particle 22 was positioned at the party's v notch v 13, and this position also is the focal position of reflective surface (parabola) or near the focal position; The processing of aluminizing of reflective surface surface; After 22 energisings of LED particle were lit, light can shine each little reflective surface, and light shines the place ahead to light fixture behind the reflective surface surface reflection; Because LED particle 22 is hidden in the square breach 13 of reflective surface upper side wall, can't see the direct light that it sends in the dead ahead of light fixture, can only see the light of reflective surface reflection, therefore can think that the light source of light fixture is area source.

Being known by Fig. 7, is the B-B profile of Fig. 5.Plastic spacer 3 by tapping screw 4 by with speculum on screw hole 14 be fastened on the speculum 1 after screwing.

Present case causes each reflective surface not on a height, but has formed stairstepping owing to the impact of lamp surface radian; If the LED module is fixed on the rear portion of reflective surface, certainly will to adopt the higher soft base plate of price, the lamp light source illumination effect is the effect of basic points of proximity light source also, and the LED particle that leaks outside and sheet material also can impact the appearance effect of light fixture; When the client had requirement to effect of lamp and cost, this utility model can solve.
