Abstract
An LED light that includes an LED light source. A thermoelectric device is configured to maintain the LED light source within a predetermined temperature range. A controller provides a pulse signal to the LED light source, so that the LED light can particularly operate as a strobe light. Such an LED light can find application in an obstruction light.
Claims18
An LED (light emitting diode) light, comprising:
- (a) an LED light source;
- (b) a thermoelectric device onto which said LED light source is mounted;
- (c) a thermoelectric device controller configured to control said thermoelectric device to maintain said LED light source within a predetermined temperature range;
