Description
Technical field
The utility model relates to a kind of integrated high power LED car light heat abstractor.
Background technology
At present, the light source of car light mainly is Halogen lamp LED and xenon lamp.LED closes because of series of advantages such as its life-span length, antidetonation, environmental protection little by little are applied to various illuminated fields as the environment protection solid lighting source of a new generation, and automotive lighting is no exception.But the luminous efficiency of LED has only 10%～20%, the remaining heat energy that all changed into.For enough brightness is provided, the power of LED car light must be enough high.Power is high more, and the heating of LED is just big more.If heat can not shed from chip internal in time, the heat of chip internal can constantly gather so, thereby causes junction temperature of chip constantly to rise.Too high junction temperature can cause a series of problems such as the drift, light extraction efficiency reduction, chip accelerated ageing of optical wavelength.
On the other hand, the working environment of automobile lamp is more abominable, and headlamp especially is with the space of automobile engine in same compactness.The air themperature in this space is owing to the influence of engine remains on 50～60 degree, and summer will be above this temperature.Under this environment conventional radiator be unaccommodated, can't guarantee the LED operate as normal, this also is the seldom reason of application of LEDs of present car headlamp.Therefore heat radiation is the technical barrier that needs emphasis to solve as far as the great power LED car light.
Summary of the invention
The utility model has proposed a kind of good heat dissipation, the moulding heat abstractor of integrated high power LED car light flexibly to the problem of existing integrated high power LED car light poor heat radiation.
Split type integrated high power LED car light radiator; Comprise car light module and radiating module; It is characterized in that: said car light module comprises heat conducting module, lampshade and led chip, and the substrate of said heat conducting module pastes on the led chip bottom surface through heat-conducting glue, and said substrate is provided with fluting along the plate face; Said radiating module comprises heat pipe and fin, and said heat pipe is divided into evaporator section, adiabatic section and condensation segment, and said evaporator section is embedded in the fluting of said substrate, and two ends link to each other with the adiabatic section respectively; Described adiabatic section coated insulation material, the other end is connected with said condensation end; Said condensation segment runs through said fin, makes said fin form layer structure, with being integral of water tank grill-shaped.
The heat that LED when work produces is mainly absorbed by substrate and the heat pipe that is embedded on the substrate, takes heat the radiating module of water tank grid place to through heat pipe, heat is shed with the air heat exchange in the vehicle body external world through fin.
The beneficial effect of the utility model is: (1) has changed heat dissipation environment, has solved the not good difficult problem of conventional radiator (monoblock type) radiating effect; (2) moulding is flexible, can satisfy the requirement of different body shapes, changes the performance that moulding does not influence light fixture.
