An LED light bulb for use as an indicator or warning lamp comprises a support structure; a generally circular and planar disc attached to the support structure, wherein the disc is a printed circuit board and is perpendicularly oriented with respect to the structure. A plurality of interconnected LEDs are concentrically mounted on the disc wherein a portion of the LEDs are outwardly splayed at an angle away from a central axis point of the disc so that the LEDs collectively transmit light having about the same light intensity at viewing angles from about 0.degree. to about 360.degree. about the disc. The LED light bulb has circuitry means for providing a current to the LEDs.

[ We claim:] [1.]1. An LED light bulb for use as an indicator lamp, task lamp, general lighting, decorative lamp, and traffic lamp, warning lamp, said LED light bulb comprising:an opaque conical base portion wherein said base portion includes a first circular opening and a second circular opening, the first circular opening having a larger diameter than the second circular opening;a generally circular and planar disc inserted into the first opening and affixed to the base portion, wherein said disc is a printed circuit board having a top planar surface and a bottom planar surface and is perpendicularly oriented with respect to base portion;a plurality of interconnected LEDs concentrically mounted on the top surface of said disc wherein at least one of said LEDs is perpendicularly oriented with respect to the disc and a portion of said LEDs is outwardly splayed at an angle relative to said disc and away from a central axis point of said disc for transmission of light having about the same light intensity at different viewing angles;a threaded socket attached to the second opening of the conical base portion; andcircuitry means located on the bottom surface of said disc and connected to the socket for providing a current to said LEDs.
