LED light bulb
First Claim
1. An LED light bulb comprising:
- a base for coupling the bulb to a power source having at least one side wall defining a cavity;
a generally rectangular substrate having a first end and a second end, the second end disposed in the cavity and electrically coupled to the base;
a plurality of LEDs electrically coupled and disposed on the first end of the substrate, the plurality of LEDS arranged on a front face, back face and top edge of the first end of the substrate to emit light in a spherical output; and
a light transmissive cover configured to enclose the plurality of LEDs, the cover being coupled to the base.

20. An LED light bulb comprising:
-
a base for coupling the bulb to a socket of a power source having at least one side wall defining a cavity, the base including a threaded portion for insertion into the socket and a skirted portion for receiving a cover;
a generally rectangular substrate having a first end and a second end, the second end disposed in the cavity and electrically coupled to the base, the substrate including a tab projecting from each side edge located adjacent the second end of the substrate configured for mating with the skirted portion of the base;
a plurality of LEDs electrically coupled and disposed on the first end of the substrate, the plurality of LEDS arranged on a front face, back face and top edge of the first end of the substrate to emit light in a spherical output; and
a light transmissive cover configured to enclose the plurality of LEDs, the cover including a recessed portion at an open end for mating with the skirted portion of the base, wherein the recessed portion of the cover further comprises two slots configured to receive the tabs of the substrate.
