Abstract (en)
An LED light source includes a housing having a base adapted to mount in an electrical socket; a circuit board received in the housing; an electrical circuit assembly received in the housing, the electrical circuit assembly being electrically connected to both the circuit board and the base; an LED assembly mounted on the circuit board, the LED assembly including a plurality of LED elements electrically connected to the circuit board; and a bulb mounted on an open end of the housing for enclosing the circuit board, the electrical circuit assembly, and the LED assembly, wherein the LED elements are arranged in three-dimension so as to irradiate an enlarged range. The LED elements may be arranged and shaped as a tapered tower, a tree, or a semi-sphere.
