Description

A kind of high-power LED Car light radiator

Technical field

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

Technical scheme: the utility model discloses a kind of high-power LED car light radiator, including car light module and radiating module, described car light module includes LED chip and for fixing the substrate of LED chip and car light, described LED chip is connected with car light and is fixed on substrate, fin that described radiating module includes being partially embedded at described substrate back and the cooling mechanism with described fin, described cooling mechanism includes and described substrate-parallel is arranged the first radiating fin and the second radiating fin of being arranged between the first radiating fin and the first radiating fin, described second radiating fin is provided with louvre.

As further optimization of the present utility model, the first radiating fin described in the utility model is equidistantly provided with some column type ribs.

As further optimization of the present utility model, the two ends of substrate described in the utility model are provided with the reflector extended at car light.

As further optimization of the present utility model, cooling mechanism described in the utility model is coated with insulation crust, and between this insulation crust inwall and first radiating fin of cooling mechanism, spacing is between two the first radiating fins 2-3 times of spacing.

As further optimization of the present utility model, insulation crust described in the utility model is provided with the heat pipe for heat conduction.

Beneficial effect: the utility model is compared with prior art, heat exchange is carried out with the external world again after having the advantage that the utility model to pass through first to use cooling mechanism that LED car lamp is dispelled the heat, ensure the radiation stability of cooling mechanism, and by cooling mechanism is arranged in insulation crust, in order to avoid components and parts deform upon the work of impact other components and parts around because temperature is too high, insulation crust is used to protect, ensure the work of components and parts around, the utility model increases reflector in substrate both sides simultaneously, in the case of vehicle lamp brightness is consistent, use radiator of the present utility model, LED power is relatively low, so fundamentally controlling heating, the utility model simple in construction, low cost, applied widely, there is good economic benefit.
