AC LED white light luminous device

摘要

An AC LED white light luminous device belongs to LED manufacturing field. The problem to be solved by the present invention is low-costly solving a problem of LED stroboflash by AC driver and solving a series of problems of heat emission difficulty caused by multi-LED integrated packaging. An LED white light luminous unit includes an LED chip and a light emitting material that can irradiate when it is excited by the LED chip. The emitting lifetime of the light emitting material is 1-100ms. The LED chip only comprises one PN junction. The light emitted by the LED chip is mixed with the light emitted by the light emitting material, and the color of the mixed light is white. The LED white light luminous unit can be driven by AC of which frequency is not more than 100 Hz. In the LED luminous device of prevent invention, it is used that single PN junction chip rather than prior integrated packaged AC multi-LED chip.
