Office lighting: LED has a difficult time conquering

Relevant organizations pointed out that in the current LED lighting market, outdoor lighting and public lighting are the markets where traditional lighting is best replaced with LED lighting. Home lighting and commercial lighting are also gradually on the road to replacement. Office lighting can be said to be a bast

Design of a high power LED constant current source series driver

引言随着大功率LED的问世，因其发光效率是一般荧光灯或白炽灯的5~7倍，节能效果十分显著。因而，大功率LED具有广泛的应用前景。目前，单个大功率LED已有1W、3W、5W和10W，已被大量使用的是1W和3W的大功率LED，采用多个大功率LED串联和并联，其组合输出功率已达70W~100W。大功率LED虽具有发光效率高和节能的优点，但其管压降的不一致却是需要克服的缺点。其次，大功率LED的温度特性较差。随着结温和环境温度的改变，其管子的电流和发光效率变化很大，这也给使用带来了不便。由于大功率LED存在以上缺点，人们在使用时多采用两种驱动方案：1.恒压源驱动。即采用多个LED并联后用恒压源驱动。这样,由于L

Next Generation Automotive Exterior Lighting LED Driver Technology Evolution

在电动汽车、ADAS和对现代风格的渴望的推动下，汽车照明正在快速发展。汽车工业继续向电气化转变，导致汽车外部照明发生显著变化。过去，大型单一功能灯控制着车辆的前部、后部或侧面。然而，围绕着汽车的更新、更薄的设计取代了他们的位置。汽车制造商正在使用灯光作为标志性的造型特征，并加入动画来象征品牌身份。这些新设计不仅美观，而且实用。 Animated taillights are not new as they first appeared on 1960 muscle cars such as the 1965 Chevrolet Impala SS. It featured a unique tailli

Analysis on Effectively Improving Heat Dissipation of High-Power LEDs

For a long time, display applications have been the main demand for LEDs. When the heat dissipation requirements for LEDs are not very high, LEDs are mostly packaged using traditional resin substrates. After 2000, with the development of high-brightness and high-efficiency LED technology, coupled with the s
