In this research, the recycled electrical energy from wasted thermal energy in high power Light Emitting Diode (LED) system will be investigated. The luminous efficiency of lights has been improved in recent years by employing the high power LED system, therefore energy efficiency was improved compared with that of typical lighting sources. To increase energy efficiency of high power LED system further, wasted thermal energy should be re-considered. Therefore, wasted thermal energy was collected and re-used them as electrical energy. The increased electrical efficiency of high power LED devices was accomplished by considering the recycled heat energy, which is wasted thermal energy from the LED. In this work, increased electrical efficiency will be considered and investigated by employing the high power LED system, which has high thermal loss during the operating time. For this research, well designed thermoelement with heat radiation system was employed to enhance the collecting thermal energy from the LED system, and then convert it as recycled electrical energy.
在本研究中,将对高功率发光二极管(LED)系统中废热能回收的电能进行研究。近年来,通过采用高功率LED系统提高了灯光的发光效率,因此与典型照明光源相比,能源效率得到了提高。为了进一步提高高功率LED系统的能源效率,应重新考虑废热能。因此,收集了废热能并将其作为电能重新利用。通过考虑回收热能(即LED产生的废热能),实现了高功率LED器件电效率的提高。在这项工作中,将通过采用在工作期间有高热损耗的高功率LED系统来考虑和研究提高电效率的问题。对于本研究,采用了设计良好的带有热辐射系统的热电偶,以增强从LED系统收集热能的能力,然后将其转换为回收电能。
