Description

A kind of car light radiator

Technical field

The utility model belongs to heat sink technology field, is specifically related to a kind of car light radiator.

Background technology

At present, the light source of car light is mainly Halogen lamp LED and hernia lamp, LED fixes lighting source as the environment-friendly type of a new generation, because its life-span is long, antidetonation, the series of advantages such as environmental protection and be little by little applied to various illuminated field and close, automotive lighting is no exception, but, the luminous efficiency of LED only has 10-20%, remaining all it is converted into heat energy, in order to provide enough brightness, the power of LED car lamp must be sufficiently high, power is the highest, the heating of LED is the biggest, if heat can not shed from chip internal in time, so heat of chip internal can constantly gather, thus cause junction temperature of chip constantly to rise, too high junction temperature can cause the drift of optical wavelength, light extraction efficiency reduces, the a series of problems such as chip accelerated ageing.

On the other hand, the working environment of automobile lamp is more severe, especially headlamp, being maintained at 50-60 ° in same compact space, the air themperature in this space due to the impact of engine with automobile engine, summer will exceed this temperature, under this environment, conventional diffusers is inappropriate, cannot ensure that LED normally works, this is also the reason that current car headlamp seldom applies LED, and therefore for high-power LED car light, heat radiation is to need emphasis to solve the technical problem that.

Utility model content

Utility model purpose: the problem and shortage existed for above-mentioned prior art, the purpose of this utility model is to provide a kind of car light radiator.

Technical scheme: the utility model discloses a kind of car light radiator; including car light module and radiating module; described car light module includes LED chip and for fixing LED chip and the substrate of car light lampshade; described substrate is bowl structure; it is provided with reflector inside its end wall; LED chip is connected with car light and is fixed on base plate bottom; described radiating module includes the column being made up of some thermal columns heat radiation bundle and is arranged on the protective cover outside described heat radiation bundle; described heat radiation bundle is connected with substrate, and the position that its position is fixed on substrate with LED chip is corresponding.

As further optimization of the present utility model, being provided with the first radiating fin between thermal column described in the utility model and thermal column, described first radiating fin is parallel with base plate bottom.

As further optimization of the present utility model, the first radiating fin described in the utility model is provided with U-shaped louvre.

As further optimization of the present utility model, the first radiating fin described in the utility model is that Y-shaped structure includes that jag portion and afterbody, described jag portion are connected with the thermal column near protective cover.

As further optimization of the present utility model, described in the utility model bundle in heat radiation is provided with the second radiating fin between peripheral thermal column and protective cover, and described second radiating fin is vertical with base plate bottom.

Beneficial effect: the utility model is compared with prior art, have the advantage that the utility model realizes the heat radiation of LED car lamp by the heat radiation bundle using thermal column to constitute, there is good heat dissipation effect, the features such as volume is little, be there is the substrate of reflector by employing, improve the light utilization efficiency of LED car lamp, and then in the case of identical intensity of illumination, use LED car lamp of the present utility model, its LED chip operating power is relatively low, and then the heat energy of generation is the most relatively fewer, the utility model is by setting up radiating fin between thermal column and thermal column, fin is set up between thermal column and protective cover, on the premise of being not take up space, it is greatly improved radiating effect.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

Below in conjunction with specific embodiment, the utility model is described in detail; but illustrate that protection domain of the present utility model is not limited to the concrete scope of the present embodiment simultaneously; based on the embodiment in the utility model; the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly falls into the scope of the utility model protection.

It should be noted that in description of the present utility model, except as otherwise noted, " multiple " are meant that two or more；Term " on ", D score, "left", "right", " interior ", " outward ", " front end ", " rear end ", " head ", the orientation of the instruction such as " afterbody " or position relationship be based on orientation shown in the drawings or position relationship, it is for only for ease of description the utility model and simplifies description, rather than instruction or the device of hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to restriction of the present utility model.Additionally, term " first ", " second ", " the 3rd " etc. are only used for describing purpose, and it is not intended that indicate or hint relative importance.
