繁华盛会聚焦世界目光，缤纷“花雨”装点美丽敦煌——2008版《丝路花雨 》 将于4月22日为中国绿公司年会开幕式演出，将为敦煌文化旅游推介代言，使敦煌文化旅游，乃至甘肃文化旅游在这次盛会上大放异彩。佰艺精工（魔龙灯光）300多台产品强势助阵，打造出震撼空前的视觉盛宴。

  The 45th Tokyo Auto Show was held at the Tokyo Big Sight from October 27, 2017 to November 5, 2017.As one of the top five auto shows in the world, the Tokyo Auto Show is an important stage for automakers to show the world. At the Tokyo Auto Show, 15 brands from 14 Japanese manufacturers and 19 brands from 13 international manufacturers were unveiled at the show.In addition, 153 companies and organizations from 10 countries also exhibited a comprehensive range of services including passenger cars, commercial vehicles, motorcycles, windows, bodies, spare parts and machinery, automotive related services.Tokyo auto show used MONON's LED auto show lights for lighting, which was highly praised by the Japanese exhibition company!

  The maturity of LED technology has gradually penetrated into the field of professional lighting, but the color rendering index CRI in the CIE chromaticity system based on the use of halogen light source has been unable to accurately evaluate the light color effect of LED. The subsequent TLCI is only for TV stations application.On May 18, 2015, the Illuminating Engineering Society of North America (IES) released a new evaluation system for light source color development capabilities - IES TM-30-15 (hereinafter referred to as TM-30) ,which evaluates the color restoring ability of light sources through color reality (Rf) and color saturation (Rg).It compensates for the problem of insufficient color parameters of traditional evaluation light source, and provides calculation support for color reduction theory.

LED驱动电路的主要功能

LED驱动电路应确保LED的恒流工作特性，尤其在电源供电电压发生变化时，仍能保持LED工作电流的稳定。实现：

　1.确保LED负载工作电流稳定;

　2.避免LED驱动电流超出最大额定值，影响LED负载的工作可靠性;

　3.获得要求的流明输出，并保证各LED发光亮度和发光色度的一致性。

同时，LED驱动电路应保持较低的功耗，这样才能使LED照明系统的工作效率保持在较高水平。

尤其在调光方面，LED 不仅可实现0~100%的调光，而且还可以保证在整个调光过程中有较高的发光效率，并不损害LED 的工作寿命

LED照明光源已经进入到普及阶段，然而，LED照明光源产生的蓝光危害却没有得到重视，很多人甚至都不了解蓝光危害的重要性，蓝光危害会成为今后的一个
