초록 ▼

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.

1. A method of controlling heat storage in a cyclically operated light emitting diode (LED) system, the LED system including a first LED, the method comprising: providing a first phase change material (PCM) in one or more plurality of containers thermally coupled to the first LED;while the LED system is turned on: absorbing and storing a first portion of heat generated by the LED system in the first PCM; andconvecting a second portion of heat generated by the LED system into an atmosphere surrounding the LED system;while the LED system is turned off: releasing heat from the first PCM; andconvecting heat away from the LED system into the atmosphere surrounding the LED system,wherein the first PCM is selected based upon heat storage capabilities of the first PCM, and further wherein the first PCM is to be used to cool the first LED during cyclical operation of the LED system. 2. The method as recited in claim 1, wherein the LED system further includes a second LED, and the first LED and the second LED have different operating temperatures, the method further including: providing a second PCM in another container thermally coupled to the second LED;wherein the first PCM is selected based on an operating temperature of the first LED, and the second PCM is selected based on an operating temperature of the second LED. 3. The method as recited in claim 1, wherein the convecting is due to temperature gradients between the surrounding atmosphere and the first LED. 4. The method as recited in claim 1, wherein the first PCM has a melting temperature that matches a working temperature of the first LED. 5. The method of claim 1, wherein the one or more containers are a plurality of containers and the plurality of containers are stacked. 6. The method of claim 1, wherein the one or more containers are a plurality of containers and the plurality of containers are nested. 7. The method of claim 1, wherein the plurality of containers are cylindrical in shape. 8. A method, comprising: selecting one or more phase change materials (PCMs) to cool a light emitting diode (LED);placing a plurality of containers in thermal contact with the LED, placing the one or more PCMs in at least one of the plurality of containers and providing water in at least one of the remaining of the plurality of containers;absorbing and storing a first portion of heat generated by the LED during its operation in the one or more PCMs;convecting a second portion of the heat generated by the LED during operation; anddissipating the heat absorbed by the one or more PCMs after the LED is turned off,wherein the one or more PCMs are selected based upon heat storage capabilities of the one or more PCMs, andoperating the LED in a cyclical application.
