Abstract:
LED lighting systems operate their LED above a junction temperature of 85° C. and space apart from the LED, components of the LED lighting system that reduce an expected lifetime of the LED lighting system to less than 25,000 hours as a result of operating the LED above the junction temperature of 85° C. Accordingly, the LED itself may be driven hotter than is conventionally the case, without impacting its lifetime. By allowing the LED to operate hotter, reduced heat sinking may be needed for the LED itself, which can decrease the cost, size and/or complexity of the thermal management system for the LED lighting system and/or can allow a thermal budget for the LED lighting system to be used elsewhere. Related structures are also described.
