Description
Technical field
The utility model belongs to heat sink technology field, is specifically related to a kind of efficiently 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 efficiently car light radiator.
Technical scheme: the utility model discloses a kind of efficiently car light radiator, including light source slot and with the cooling mechanism being connected bottom described light source slot, described light source slot is that cylindrical groove includes the rounded trough bottom for fixing LED chip and cell wall, described cell wall height is the 1/4-1/3 of groover rot diameter, being provided with annular reinforcing plate between described bottom land and cell wall bottom, this annular reinforcing plate is connected with bottom land and cell wall by rib is fixing.
As further optimization of the present utility model, the top of annular reinforcing plate described in the utility model is less than the upper surface of bottom land.
As further optimization of the present utility model, to extending to cooling mechanism and being connected with cooling mechanism upper surface under annular reinforcing plate plate face described in the utility model, downwardly extend height for the 1/3 of annular reinforcing plate internal diameter.
As further optimization of the present utility model, cooling mechanism described in the utility model is a few font columnar structures, and this cooling mechanism inside is hollow structure.
As further optimization of the present utility model, cooling mechanism inwall described in the utility model is vertically provided with some reinforcements.
As further optimization of the present utility model, cooling mechanism bottom described in the utility model is provided with groups of fins.
Beneficial effect: the utility model is compared with prior art, have the advantage that the utility model is equipped with in LED chip bottom by annular reinforcing plate and rib, it is capable of LED chip is carried out heat radiation rapidly and efficiently, the cooling mechanism using a few character form structure again coordinates the groups of fins being positioned at its bottom, its structural volume is little, excellent in heat dissipation effect, by being provided with reinforcement on cooling mechanism inwall, the wall thickness of cooling mechanism can be reduced to a certain extent, improve radiating effect, for ensureing the overall construction intensity of cooling mechanism, therefore groups of fins is set in the bottom of cooling mechanism, while strengthening structural strength, by further improving radiating effect, therefore use car light radiator of the present utility model, can effectively extend LED chip service life, there is good economic benefit.
