LED device with shared voltage-limiting unit and individual equalizing resistance
Abstract:
The present invention relates to a LED device with shared voltage-limiting unit and individual voltage-equalizing resistance, wherein two ends of a LED set constituted by a plurality of same-polarity series LEDs are in parallel connected with a shared voltage-limiting unit, and two ends of individual LED are respectively in parallel connected with an voltage-equalizing resistance for providing an overvoltage protection to the LEDs.
Abstract(Chinese):

本发明涉及具有共享电压限制单元和单独的电压均衡电阻的LED器件，其中由多个相同极性的串联LED构成的LED组的两端与共用电压限制单元并联连接， 各个LED的两端分别与用于向LED提供过电压保护的电压均衡电阻并联连接。
