摘要： A compound light source that compensates for changes in electrical conversion efficiency with increasing operating temperature is disclosed. The compound light source generates light of a design intensity at a design temperature in response to a drive current flowing through the light source. The light source includes a primary light source and a compensating light source. The primary and compensating light sources convert an electrical current passing therethrough to light, each light source being characterized by an electrical conversion efficiency that decreases with increasing temperature and that also decreases with increasing current. The compound light source includes a temperature sensor that measures the temperature of the primary light source and a current splitting circuit that divides the drive current between the primary and compensating light sources to compensate for the decrease in efficiency of the primary light source with temperature above the design temperature.

摘要： A lighting apparatus and method for operating LED-based lighting devices are disclosed. The apparatus includes a receiver that receives a potential from a power source whose output varies as a function of time, an energy storage device, and an LED array. The energy storage device stores energy from the power source when the driving potential is greater than a predetermined value. The LED array has variable forward bias potential, the LED array generating light when a potential across the array is greater than the selected forward bias potential. A source selector connects the energy storage device to the array when the potential from the power source is less than a predetermined value. A controller that varies the forward bias potential such that the difference between the forward bias potential and potential across the array is maintained at a value less than a predetermined value.
