LED light source of claim 1, leakage current LED is one-way conductive light, if there is reverse current is called leakage, the leakage current is large LED, life is short, low prices. 2, uses a different angle LED luminous light emitting angle is not the same. Special light-emitting angle, and higher prices. If all diffusion angle, and higher prices. 3, the key is the quality of life of different life, Baoji box lights wholesale, life determined by the light fades. Light is small, long life, light boxes lights, long life, high price. 4, chip LED luminous body for the chip, different chips, prices vary widely. Japan, the United States more expensive chips, generally made in Taiwan and chip prices lower than Japan, the United States. LED chips LED light introduced to occupy a major part of the cost of the LED lamp, thereby reducing the cost of the main route LED is to reduce the cost of LED chips. LCOS low end of the cost, technology continues to progress, but the luminous efficiency is still not satisfied, if you keep this growth rate, once they reach a higher level, then at the end to become the most important technology of silicon-based solutions become an inevitable choice, companies will also get huge economic returns.
