THERMAL STORAGE SYSTEM USING PHASE CHANGE MATERIALS IN LED LAMPS |
摘要 |
A phase change material (PCM) is used for thermal storage for LED-based lighting systems. The PCM is placed in multiple sealed containers in thermal contact with the LED to be cooled. The PCM is selected such that its melting point temperature is substantially the preferred operating temperature of the LED. When the LED is on, the PCM absorbs and stores some of the heat generated by the LED, while some of the generated heat is convected away from the LED. The PCM is selected based upon its heat storage capabilities to cool the LED when the lighting system is operated for a cyclical application. |
