Description
技术领域technical field
本实用新型涉及一种大功率LED的散热技术，特别是涉及面光源的大功率LED的散热结构。The utility model relates to a heat dissipation technology of a high-power LED, in particular to a heat dissipation structure of a high-power LED of a surface light source.
背景技术Background technique
COB 即chip On board的简写，就是将裸芯片用导电或非导电胶粘附在互连基板上，然后进行引线键合实现其电连接，COB LED又叫COB LED 光源,COB LED模块。自COB LED问世到现今,散热一直是最大的课题,早期COB LED因为光电转换技术停留在20%的光、80%的热使得COB LED在大功率应用上一直无法实现,近年来COB LED在封装技术上的突破,使得COB LED发光效率提升，进而开始有厂商着手在散热上进行改善,让COB LED在大功率的应用从100W发展到现在单颗500W的COB LED。许多COB LED灯具设计散热时只考虑其热源后方的散热设计,但其实COB LED在使用时前方的辐射热也相当可观。COB is the abbreviation of chip On board. It is to adhere the bare chip to the interconnection substrate with conductive or non-conductive adhesive, and then perform wire bonding to realize its electrical connection. COB LED is also called COB LED light source and COB LED module. Since the advent of COB LEDs to the present, heat dissipation has always been the biggest issue. In the early COB LEDs, because the photoelectric conversion technology stayed at 20% light and 80% heat, COB LEDs have been unable to achieve high-power applications. In recent years, COB LEDs have been used in packaging Technological breakthroughs have improved the luminous efficiency of COB LEDs, and some manufacturers have begun to improve heat dissipation, so that the application of COB LEDs in high-power applications has developed from 100W to a single 500W COB LED. Many COB LED lamps only consider the heat dissipation design behind the heat source when designing heat dissipation, but in fact, the radiation heat from the front of COB LEDs is also considerable when they are in use.
COB LED在灯具上的光学应用包括使用光学玻璃透境和铝制反光杯等，这几种光学应用会直接影响光源所产生的辐射热的散热。现有使用光学玻璃透镜的情况，辐射热闷在狭小空间中,如在冬天内外温差大时会导致玻璃透镜破裂。而现有使用铝制反光杯的灯具,基本上没有把辐射热的散热考虑进去,直接放置反光杯后用防水装置密封，长时间后铝制反光杯会变形或者反光杯表面涂层雾化而导致灯具发光效率降低。The optical applications of COB LEDs on lamps include the use of optical glass and aluminum reflectors, etc. These optical applications will directly affect the heat dissipation of radiant heat generated by the light source. In the existing situation of using optical glass lenses, the radiant heat is stuffy in a small space, such as when the temperature difference between inside and outside is large in winter, the glass lens will break. However, the existing lamps using aluminum reflectors basically do not take the heat dissipation of radiant heat into consideration. The reflector is directly placed and sealed with a waterproof device. After a long time, the aluminum reflector will be deformed or the surface coating of the reflector will be atomized. The luminous efficiency of the lamp is reduced.
