The development direction of led lights

High power LED street light for outdoor applications, not only to solve the problem of uniformity, luminance, at the same time also to have certain requirements in terms of light distribution, which cover the area to be big enough, the light can stretch around. In this way can we achieve the LED lighting on real consciousness, '

as a kind of outdoor applications, high power LED street light not only need to solve the problem of uniformity and brightness, and also to have certain requirements for light distribution, namely coverage should be enough big, the light can control. Only in this way can we achieve real conscious led lighting. Combining the present situation of the application of high power outdoor lighting, and its technology research and development will be focused on the following aspects: one is to improve the luminous efficiency and luminous flux, reduce packaging thermal resistance, improve the secondary optical design, to improve the brightness of the light emitting diode light source; Second, strengthen the research and development, the power supply system of high power LED street lamps need constant current drive power to ensure that the LED street light of constant power output, especially in our country under the condition of the power supply is not stable, it is more important. Third, increase the single arm light pole, to strengthen the research and development of light-emitting diode chip, to realize the core technology of democracy, to further reduce the cost of led lighting lamps and lanterns.
