업무용 건축물의 LED조명기구 표면온도 측정을 통한 발열량 산출에 관한 연구

LED lights have attracted attention as next-generation light source for reasons, which are high efficacy and long life. However, according to many studies, heat from LED fixture can be a factor that increase indoor environmental cooling load since 80% of input power of LEDs emits in convective heat. In this study, we measured temperature of indoor air and surface of LED fixture by using thermocouple and calculated heat from LED fixtures installed in office module by 2 person. As a result of calculation, power consumption 40W LED lights, which turned out to be a 30W for heat.
