Led light bulb

摘要

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° to about 360° about the disc. The LED light bulb has circuitry means for providing a current to the LEDs.
