Abstract

The invention relates to the technical field of automobile illumination, in particular to an automobile lamp comprising a lamp housing. A transparent mask is arranged at the opening end of the lamp housing, and a cavity for accommodating different LED lights is formed between the lamp housing and the mask. A clearance lamp unit comprises small LED lights, light holders and diffusers; the light holders are disposed in the cavity and arranged along the automobile width, the small LED lights are arranged on the light holders at equal intervals, and each light diffuser is arranged on one side, along the light emitting direction, of each small LED light. The clearance lamp unit is composed of multiple LED lights instead of single light source, and by the aid of the diffusers arranged, light emitted from the clearance lamp unit is uniform, and the uneven lighting to different places is avoided.

Description

Automobile lamp

Technical field

The present invention relates to automotive lighting technical field, particularly a kind of automobile lamp.

Background technology

In prior art, in many automobiles and truck, the backlight electric power of instrument board, interior lighting and brake lamp, the trace of the LED that is seen everywhere.LED car light is all generally to consist of reflector and LED light source, because LED light source is similar to the effect of spot light, therefore all very easily there is bright spot and dark space in the light-emitting area of whole LED car light, thereby cause whole lamp brightness irregularities, this not only affects the attractive in appearance of car light, and have influence on warning and the illumination functions of car light, especially the forward and backward clearance lamps of automobile all has higher requirement for warning and the illumination functions of light, if the brightness disproportionation of forward and backward clearance lamps or brightness not only affect the attractive in appearance of car light, and traffic safety is also had to considerable influence.

Summary of the invention

The object of the present invention is to provide a kind of automobile lamp, effectively improve the uniformity of clearance lamps light.

For realizing above object, the technical solution used in the present invention is: a kind of automobile lamp, comprise lamp housing, and the opening end of lamp housing is provided with transparent face shield, forms the cavity that holds each LED lamp between lamp housing and face shield; Clearance lamps unit comprises little LED lamp, lamp socket, the even light shield being arranged in described cavity, described lamp socket is positioned at cavity and arranges along overall width direction, described little LED lamp arrange a plurality of and on lamp socket evenly interval arrange, light transmit direction one side that is positioned at little LED lamp arranges described even light shield.

Compared with prior art, there is following technique effect in the present invention: the illumination of clearance lamps consists of a plurality of little LED lamps, it is no longer single spot light, and by the even light shield arranging, the light that clearance lamps is sent is more even, avoids occurring that some local light is bright, the phenomenon of some local dark lighting.

Accompanying drawing explanation

Fig. 1 is perspective view of the present invention;

Fig. 2 is perspective view of the present invention, does not comprise even light shield;

Fig. 3 is even photomask structure schematic diagram;

Fig. 4 is the enlarged diagram in broken circle in Fig. 3.

The specific embodiment

Below in conjunction with Fig. 1 to Fig. 4, the present invention is described in further detail.

Consult Fig. 1, Fig. 2, a kind of automobile lamp, comprises lamp housing 10, and the opening end of lamp housing 10 is provided with transparent face shield, forms the cavity 11 that holds each LED lamp between lamp housing 10 and face shield; Clearance lamps unit 20 comprises little LED lamp 21, lamp socket 22, the even light shield 23 being arranged in described cavity 11, described lamp socket 22 is positioned at cavity 11 and arranges along overall width direction, described little LED lamp 21 arrange a plurality of and on lamp socket 22 evenly interval arrange, light transmit direction one side that is positioned at little LED lamp 21 arranges described even light shield 23.Owing to being provided with a plurality of little LED lamps and even light shield 23, the light of clearance lamps unit 20 is more even, no longer occurs the situation of bright dark inequality.In addition, lamp socket 22 recited above is arranged along overall width direction, refers to the trend substantially of lamp socket 22, what it also can be as shown in this embodiment, its one end bends downwards, as long as the function that its integral body can play illumination, warn.

Further, described even light shield 23 integral body are the ribbon transparent body, because little LED lamp 21 is that lamp socket 22 length directions of postponing are evenly spaced apart, even light shield 23 is in order to play the effect of uniform light to each little LED lamp 21, and the length direction of even light shield 23 is consistent with the length of lamp socket 22 with the identical and even light shield 23 of length direction of lamp socket 22.

Consult Fig. 3, the set-up mode of even light shield 23 is various, here preferably, at even light shield 23, near little LED lamp 21 1 sides, be provided with striped, the position of described striped is corresponding with the position of little LED lamp 21, even light shield 23 is smooth plane away from the exiting surface 231 of little LED lamp 21 1 sides, and the light of little LED lamp 21 emits uniformly from exiting surface 231 after striped refraction.Described striped is dentation along the cross section of even light shield 23 length directions, be the dentate stripe of ten fringe area on the left side in Fig. 3 all as shown in Figure 4, in Fig. 3, the striped trend of the fringe area in the right is perpendicular to Fig. 4, the benefit of dentate stripe is not only can improve the light uniformity, but also can expand the irradiating angle of light.

As preferred version of the present invention, described lamp socket 22 is postponed to the top of cavity 11 from a side of cavity 11, and the lamp housing 10 edge contour trends of postpone direction and its side of lamp socket 22 match, and lamp socket 22 is ladder-like arranged along its length.Lamp socket table top 221 is vertical with the travel direction of vehicle, and lamp socket terrace 222 connects two adjacent lamp socket table tops 221, and little LED lamp 21 is arranged on lamp socket table top 221.Arrange like this and can guarantee that the direction of illumination of each little LED lamp 21 is to be parallel to vehicle heading, when little LED lamp 21 is arranged like this, noted earlier and the even interval of each little LED lamp 21 layout refer to: the shaft core line interval of each little LED lamp 21 is identical.

Correspondingly, described even light shield 23 is stepped and match with the stepped of lamp socket 22 near a side of little LED lamp 21, even light shield table top 232 is vertical with vehicle heading, and even light shield terrace 233 connects two adjacent even light shield table tops 232, and described striped is arranged on even light shield table top 232.Between even light shield table top 232 and lamp socket table top 221, there is space for arranging described little LED lamp 21; Even light shield terrace 233 is shiny surface, arranges that structure after dentate stripe as shown in Figure 4 on even light shield table top 232.

It should be noted that in accompanying drawing it is the structural representation of clearance lamps before vehicle, the solution of the present invention is equally applicable to rear clearance lamps, rear brake lamp, and only control circuit part is different, or little LED lamp 21 quantity are different.
