led light boxes away Lighting Technology Co., Ltd., the main production led light boxes, power side-emitting lights, rolling lights, light bar, light bar Raab boxes, scrolling light box lights, community boxes, emitting light bar uniform light effect lifelike, low energy consumption, the installation process more convenient. 1. High power led luminous efficiency is still much room for improvement. led light source efficiency more than three generations ago, but the theoretical maximum value from very far, which means that it has great potential for development. led the internal quantum efficiency can do very generally be more than 90%, but the external quantum efficiency is generally low. If you can greatly improve the external quantum efficiency, light boxes lights, it can greatly improve the luminous efficiency led products. This is one of the key research project led. Also, when talking about efficiency led light source when the station box lights, to distinguish between several concepts. First, the laboratory led light reaches the light effect, does not mean that the luminous efficiency of existing products, it also solve the production process and other issues to become a volume product. Therefore it represents the future of light-efficient products. Second, low color rendering index products luminous efficiency, luminous efficiency does not mean that high color rendering index products. Some manufacturers when advertising their products, said light-efficient products reach the number streaming Ming Wa, community box lights, is a relatively low value of CRI led light, led light up high color rendering index value less than the advertised . There, led light, high color temperature light source than the low color play high luminous efficiency, 5600K is higher than 3200k led the led light effects. These characteristics led to understand, easy to correctly choose the desired products. 2. To improve the color rendering index is an important issue led light. In general, high color rendering index, shelters box lights, light efficiency is often lower; high luminous efficiency, color rendering index fan. Some applications, such as film, stage lighting, color rendering index of the light source on demanding. Road rod boxes lights, light boxes lights, high beam illumination provided by the far-Lighting Co., Ltd. Far Lighting Technology Co., Ltd. (www.ygzmkj.com) (www.ygzmkj.com) strong, credible, in Dezhou advertising lighting industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead away lighting and you work into the brilliant, for a better future!
