Technical field

The present invention relates to auto parts and components technical equipment fields, are concretely related to a kind of vehicle front lighting heat sink for lamp.

Background technique

LED light source is that one kind is high-efficient, the service life is long, adjustable color, green light source small in size, anti-seismic performance is strong, is based on Its above-mentioned advantage, has been used as the headlamp light source of automobile at present.Using process of the LED light source as headlamp light source In, it needs to carry out light distribution to it, so that the light that guarantee LED light source is issued meets the light distribution requirements of car headlamp.So mentioning It is very necessary for a kind of light distributing system of LED headlamp.

The light distributing system of LED headlamp common at present is divided into reflecting type light distribution system and transmission-type light distributing system, wraps Include reflecting mirror and the reflection kernel that is arranged in inside reflecting mirror at LED light source, wherein LED light source is horizontal positioned.Further Ground, transmission-type light distributing system further include: the baffle and convex lens that the open end of reflecting mirror is set gradually forward.Pass through both the above Light-configuration mode reaches to the height of LED light source with light utilization efficiency.The inventor finds that the existing technology has at least the following problems:

Summary of the invention

Therefore the present invention proposes a kind of vehicle front lighting heat sink for lamp, reinforces heat dissipation, and be avoided that dust.

The technical scheme of the present invention is realized as follows: a kind of vehicle front lighting heat sink for lamp, including reflector and with it is anti- The lampshade of light shield connection, one end of the separate lampshade of the reflector are equipped with baffle, and the baffle, which is equipped with, to be located in reflector The first LED light source, be equipped with reflector in the cavity inside that reflector and lampshade are formed, be equipped with second at the middle part of reflector LED light source；Through-hole is opened up on the baffle, heat-radiating rod is slidably connected in the through-hole, the heat-radiating rod surface is along length side To several grooves are opened up, groove interval is arranged, and reflector described in groove is externally provided with the driving cylinder being mounted on vehicle frame, drives gas The output end and heat-radiating rod of cylinder are connected far from one end of lampshade；It is spaced apart on the baffle and is equipped with several camber line gas being bent upwards Road, air flue one end offset with heat-radiating rod surface, the cavity connection that the other end and reflector and lampshade are formed.

Further, the gap size between the interval between air flue and groove is consistent.

Further, driving cylinder drives heat-radiating rod back and forth movement, and when at maximum displacement, radiate stick end and baffle An end margin close to lampshade flushes, and each groove in heat-radiating rod connects with corresponding air flue；When at least displacement, Heat dissipation stick end is located in through-hole.

Further, reflector is U-shaped structure, and inside and outside two sides is reflecting coating.

The working principle of this programme and the utility model has the advantages that

This programme includes reflector and the lampshade that connect with reflector, and the two connects to form hollow cavity, reflector it is remote One end from lampshade is equipped with baffle, and hollow cavity is sealed by baffle；

Baffle is equipped with the first LED light source being located in reflector, is equipped in the cavity inside that reflector and lampshade are formed Reflector is equipped with the second LED light source at the middle part of reflector, and reflector is U-shaped structure, and inside and outside two sides is reflecting coating, Light a part that first LED light source and the second LED light source issue directly projects lampshade, respectively by reflector and instead there are also part By projecting lampshade after the reflection of tabula rasa, wherein that there are also parts is anti-at the back side for being irradiated to reflector for the light of the first LED light source It is mapped to reflector, projects lampshade after then being reflected again, by two light sources of setting and setting reflector, improves light distribution Utilization rate, so that the intensity of illumination of car headlamp is higher.

Through-hole is opened up on baffle, heat-radiating rod is slidably connected in the through-hole, and the heat-radiating rod surface is opened along its length If several grooves, groove interval is arranged, and reflector described in groove is externally provided with the driving cylinder being mounted on vehicle frame, drives cylinder Output end and heat-radiating rod are connected far from one end of lampshade；It is spaced apart on the baffle and is equipped with several camber line air flues being bent upwards, Air flue one end offsets with heat-radiating rod surface, the cavity connection that the other end and reflector and lampshade are formed, the interval between air flue with Gap size between groove is consistent, driving cylinder drive heat-radiating rod back and forth movement, when at maximum displacement, heat dissipation stick end with Baffle is flushed close to an end margin of lampshade, and each groove in heat-radiating rod connects with corresponding air flue, at this time in cavity Hotter gas can enter groove by air flue, subsequent heat-radiating rod is driven by driving cylinder so that groove leaves the logical of baffle The contact of the external world Kong Bingyu, hotter gas four will be dissipated and be left in script groove, realize heat dissipation, the every round trip change of heat-radiating rod A gas exchanges are realized, namely realize a heat exchange, and then accelerate heat dissipation；In entire motion process, heat-radiating rod Through-hole is not completely disengaged, so that cavity and the external world are in state of isolation, the pollution of dust is avoided while heat dissipation；And Air flue is bent upwards, and is also possible to prevent dust and is entered cavity, and pollution light source is prevented.
