First Claim
Patent Images
1. A light device for illumination by a power supply circuit comprising:
- a bulb portion,a pair of end caps disposed at opposite ends of the bulb portion, the pair of end caps including;
a first end cap disposed at one end of the bulb portion; and
a second end cap disposed at an end of bulb portion opposite the first end cap, wherein the bulb portion and the pair of end caps are dimensioned to be mounted in a fluorescent light tube socket; and
a plurality of light emitting diodes disposed inside the bulb portion along one surface of a circuit board extending between the pair of end caps for illuminating in response to electrical current to be received from the power supply circuit; and
wherein each of the plurality of light emitting diodes is mounted at an angle with respect to surface of the circuit board to establish a predetermined radiation pattern of light emitted from the bulb portion between the pair of end caps.
