Background technology
LED is with its small volume, life-span length, energy consumption are low, vibration resistance, starting time are fast etc., and advantage has become as young mobile
The first-selection of light source technology.LED is a kind of injection lelctroluminescence device, in the presence of extra electric field, the radiation in electronics and hole
It is combined and part energy is converted into luminous energy, and remaining energy is converted into heat energy by the vibration of the lattice of radiationless compound generation.
Conventional light source to be replaced in car headlamp for LED, it is necessary to possess high-power, high efficiency and operating temperature
In -40 DEG C～125 DEG C of high reliability.In these functional requirements are realized, wherein a more formidable part is radiating
Problem, for single led, if heat is concentrated in small-sized chip and effectively can not be shed, can cause core
Piece temperature is raised, and is caused the non-uniform Distribution of thermal stress, is made chip failure.
Automotive LED headlamp is limited due to space, the vibration during travelling in addition, and the requirement to stability is very high, this
The radiating difficulty of LED car lamp is both increased a bit.Heat-conducting plate or heat pipe be it is possible to additionally incorporate in most heat sink conception car light at present, increase
Car light production complexity is added.
Therefore, the temperature rise for how controlling LED automobile lamp is that LED key in the urgent need to address in automotive lamp applications is asked
Topic.
