LED light bulb

摘要

An LED lightbulb is disclosed. The LED lightbulb includes an LED array mounted to a circuit board having at least two different sets of LEDs that emit correspondingly different spectra when energized. The LED lightbulb also include a interior reflective surfaces and a dome shaped diffuser lens that eclipses a portion of the LED array. The LED array, the interior reflective surfaces and the dome shaped diffuser lens are position within a cavity formed by a housing with cooling fins and an outside diffuser lens. The LED lightbulb also include a base portion for electrically coupling to a power source of a light fixture that is either an incandescent light fixture or a fluorescent light fixture. In accordance with the embodiments of the invention the LED lightbulb include a driver circuit for providing output power to the LED array from a power source having a ballast or a power source without a ballast.
