Green-lighting recyclable device of LED-MGVC

摘要

There are many benefits for high-power Light Emitting Diode (LED) lamp including weightless, anti-seismic and small size and other advantages of energy saving lighting. And a vapor Chamber (VC) can replace the current five kinds of LED boards (PCB, MCPCB, IMS, CS, and DCBS) and become a new generation of high power LED vapor chamber-based plate resulting from the high heat transfer efficiency, light weight and anti-gravity [1]. Nevertheless, about 80% of electrical input power of high power LED lighting will be in the form of waste heat energy for the LED thermal management. Therefore, this paper is to study the high-power LED lighting technology green energy power for Micro-Generator with LED Vapor Chamber-Based Plate (LED-MGVC) device characteristics, in order to reach the green recycling of lighting energy efficiency. Power generation chip analysis with thermal performance-illumination experiment is utilized in this study that can deduce and verify the best current value Iη of LED-MGVC based on thermoelectric physical phenomena constituting the basic thermoelectric effect theory. The present study develops an original device of LED-MGVC, which composing a Thermoelectric Generator Modules (TGM) with the characteristics and components of LED-VCPCB [2], will absorb the waste heat energy from the LEDs source and convert thermal energy into electrical energy, in order to achieve the best thermal management of high power LED lighting modules.
