by:SRS     2021-04-29
LED street lamp with conventional street lamps, the LED light source adopts low voltage dc power supply, by GaN power type synthetic efficiency white light, blue light leds and yellow is efficient, safe, energy-saving, environmental protection, long service life, fast response speed, high color rendering index of unique advantages, can be widely used in road. Housing available, resistance to high temperature of 135 degrees, low temperature resistant da 45 degrees. 1, a single LED low power. In order to obtain high power, require multiple parallel to use. 2, low color rendering. Under the LED light shows the color of the incandescent light bulbs, not real, it will come up from spectral distribution analysis, belongs to the technical problems. 3, light spot. Due to the defect on manufacturing process to add white LED and the matching of the reflective glass or lens error, easy to 'yellow' problem. 4, LED illumination uniformity problems. If not the secondary optical design, the LED light is more concentrated, so be sure to the secondary optical design, make the light intensity distribution of bat form. 5, the LED light failure problem. Compared with the small power LED, high power LED street lamp light failure will be much better. But small power LED heat dissipation is very small. And high power LED is heat there is no way to solve the problems, and after the fever brightness will decrease, so the power not to do. Now * big market sales Spark LED street lamp is 360 w.
