solar LED lighting lamps and lanterns of analysis for the power type LED light output coefficient, uniform light radiation direction one-way. In LED packaging, if in a light mouth with different refraction Angle of the lens, the LED street lamp, injection of beams with different radiation Angle. We will according to the characteristics of the expensive unit workshop lighting, reasonable choose appropriate radiation Angle of LED lights. When the LED for street light, can choose a set of large Angle LED emission Angle is 1400. When installation LED light axis can be tilted outward 300 ~ 450, this is according to region illumination can be made more homogeneous. The LED light does not need to use any reflection lampshade, also do not need to use any mask deco. Most of its energy shoots straight into the ground by the light source. Because the street lamps height in 3. More than 5 m, and the light power per unit area is lower than incandescent bulbs, so do not have glare, without using any of the mask to hide. As a result, the efficiency of LED street lamps and lanterns can be as high as 95. As mentioned above ivory ball steep light, with the total luminous flux reaches the ground 30 W energy-saving lamp is 630 lm, which adopts 80 lm/W LED by 11 W, do not need to cover, its energy saving effect is very significant.
