As an outdoor application, high-power LED lamps not only need to solve the problems of uniformity and brightness, but also have certain requirements in light distribution, that is, the coverage area should be large enough, and the light can be stretched left and right. Only in this way can the LED lighting be realized in real consciousness. Combined with the current application status of LED high-power outdoor lighting, its technology research and development will focus on the following major aspects in 2012: first, improve the light output efficiency and luminous flux. reduce package thermal resistance, improve secondary optical design and improve LED light source brightness; Second, strengthen the research and development of power supply system. High-power LED lamps need constant current to drive power supply, so as to ensure the constant output power of LED lamps, especially the current situation of unstable power supply voltage in our country, which is more important. Third, strengthen the research and development of LED chips, realize the autonomy of core technologies, and further reduce the cost of LED lighting fixtures.
