SYSTEMS AND METHODS FOR LED BASED LIGHTING

摘要

Various systems and methods for lighting are disclosed. For example, some embodiments of the invention (100) provide methods for retrofitting lights. The methods include providing a solid state light bulb. The solid state light bulb includes: an LED array (150), a dimming control circuit (120), and a current regulator (130). The current regulator provides an LED current to the LED array. The LED current varies based on a control from the dimming control circuit. The methods further include, electrically coupling the solid state light bulb to an existing incandescent dimmer switch (190), and adjusting the existing incandescent dimmer switch such that the intensity of light emitted from the LED array is adjusted in proportion to the adjustment of the existing incandescent dimmer switch.
