Energy Harvesting Through Wasted Thermal Energy by Light Grid Sources

초록

In this study, emitted light energy and the recycling of thermal energy from the arrays of a light emitting diode system were investigated. A light grid system is composed of the array of high power LED chips, thermoelement and heat sink. High power LED source has an advantage of high luminous efficiency, which combined with wasted thermal energy. Thermal energy loss can be regarded wasted energy. However, this wasting thermal energy can be effectively converted to the electrical energy from thermoelement and heat sink of a light grid system. By introducing the light grid system, the optical energy and thermal energy can be more effectively managed. In particular, we have intensively studied energy conversion efficiency of light grid system and energy harvesting characteristic through thermal energy.
