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.
在本研究中，对发光二极管系统阵列发出的光能以及热能的回收进行了研究。一个光栅系统由高功率LED芯片阵列、热电偶和散热器组成。高功率LED光源具有发光效率高的优点，同时伴随着热能的浪费。热能损失可被视为浪费的能量。然而，这种浪费的热能可以通过光栅系统的热电偶和散热器有效地转化为电能。通过引入光栅系统，可以更有效地管理光能和热能。特别是，我们深入研究了光栅系统的能量转换效率以及通过热能进行的能量收集特性。
