Description

A kind of LED car headlamp

Technical field

The utility model relates to the technical field of automotive lighting, refers in particular to a kind of LED car headlamp.

Background technology

Known in the industry, LED (light emitting diode) be utilize electron hole in semi-conducting material in conjunction with time the change on rank, energy band position, with its energy being discharged of luminescence display, there is the advantages such as volume is little, the life-span is long, driving voltage is low, power consumption is few, reaction rate is fast, electric durability is good, the illuminating part of commonly using for the various lightings of normal lighting.

At present, along with the universal and scientific and technical development of automobile, the performance of the each parts of automobile also constantly gets a promotion and improves, and car headlamp is as the important light fixture of vehicle safety travel, also be one of improved object wherein, from existing car headlamp, it still has larger room for promotion.For example, existing car headlamp is confined to structural design own, its radiation response and waterproof effect are general, and even some is more low, simultaneously owing to mostly also adopting the conventional light source such as Halogen lamp LED, not only energy consumption is high for it, not environmental protection, and more seriously, its service life is short, change frequently, can make troubles to user like this.So the car headlamp of prior art remains to be further improved.

Utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art, and the LED car headlamp of a kind of compact conformation, safe and reliable, energy-saving consumption, long service life, good waterproof performance is provided.

For achieving the above object, technical scheme provided by the utility model is: a kind of LED car headlamp, include strip lamp housing, the beam projecting mouth of this strip lamp housing adopts face mirror to seal, its both sides in the longitudinal direction dispose respectively end cap, wherein, in described strip lamp housing, be provided with the LED beam projecting group that many groups distribute along its length, every group of LED beam projecting group includes reflector, lens and LED light source, described LED light source is configured in reflector, and towards the lens in its front, described lens are between LED light source and face mirror.

Between the front end of described strip lamp housing and face mirror, pad has sealing strip, and between the both sides of this strip lamp housing on its length direction and end cap, pad has waterproof pad respectively.

One side of described strip lamp housing is provided with porous plug.

Described many group beam projecting groups are arranged with at least one row.

Described lens are flat structure, and its one end towards face mirror is arc tips.

Compared with prior art, tool has the following advantages and beneficial effect the utility model:

1, by specially designed LED beam projecting group, organically combine by reflector, lens and LED light source, make the radiation response of light fixture more remarkable, and then can effectively improve traffic safety, avoid accident to occur;

2, add waterproofing design by the front end at strip lamp housing and both sides, make the waterproof effect of light fixture better, thereby can effectively guarantee the normal use of light fixture;

3, by the side at strip lamp housing, porous plug is set, the air-tightness that can effectively realize light fixture detects, and importantly can make the inside and outside pressure equilibrium of light fixture, thereby guarantees the normal use of light fixture;

4, adopt LED light source to replace conventional light source, play energy-conservation, economize the effects such as consumption, environmental protection, attractive in appearance, reaction is fast, increase the service life;

5, product appearance is more beautiful.

Detailed description of the invention

Below in conjunction with two specific embodiments, the utility model is described in further detail.

Embodiment 1

Referring to shown in Fig. 1 to Fig. 6, LED car headlamp described in the present embodiment, include strip lamp housing 1, the front end of this strip lamp housing 1 is beam projecting mouth, employing face mirror 2 seals, its rear end is heat radiation position, its both sides in the longitudinal direction dispose respectively end cap 3 simultaneously, wherein, in described strip lamp housing 1, be provided with the LED beam projecting group that many groups distribute along its length, this many group LED beam projecting group is arranged in a row, every group of LED beam projecting group includes a reflector 401, lens 402 and a LED light source 403, described LED light source 403 is configured in reflector 401, and be fixed on respective lines plate 7, and towards the lens 402 in its front, described lens 402 are between LED light source 403 and face mirror 2, its entirety is flat structure, its one end towards face mirror 2 is arc tips.The light that such design can make LED light source 403 send, part is finally gone out from 2 transmissions of face mirror after reflector 401 reflections, part is gone out from 2 transmissions of face mirror after lens 402 transmissions again, thereby forms good outgoing effect, and free from glare, bright dipping are evenly soft, comfortable.

In addition, in order to improve the water proofing property of light fixture, guarantee normal use and the service life thereof of automobile front, described in the present embodiment, between the front end of strip lamp housing 1 and face mirror 2, pad has sealing strip 5, simultaneously, between the both sides of this strip lamp housing 1 on its length direction and end cap 3, also pad has waterproof pad 6 respectively, and such design can make this LED car headlamp have omnibearing water-proof function, forms good waterproof effect.
