Abstract: A system for automatically adjusting light intensity of a lighting fixture having multiple emitters, includes a power supply for supplying at least one current source to multiple emitters, at least one first emitter capable of emitting light of a first wavelength, at least one second emitter capable of emitting light of a second wavelength and a luminous intensity adjusting circuit for adjusting light intensity of the at least one first emitter. Particularly, the luminous intensity adjusting circuit stabilizes a first current distributed from a feeding current of the at least one current source and the multiple emitters collectively emit light at a predefined variable light-intensity.

Abstract: A light source for producing variable illumination coupled to at least one device includes a light chip assembly, and an LED driver module. The light chip assembly includes multiple LEDs on a silicon substrate, a heat-sink coupled to the light chip assembly, the silicon substrate being coupled to an inner core region of the heat-sink via a thermally conductive adhesive. The LED driver module includes housing, a load stabilization LED driver circuit within the housing, the load stabilization LED driver circuit being configured to drive the light chip assembly, a printed circuit coupled to the load stabilization LED driver circuit and a power supply for providing an alternating current.
