Patent ID: 7802901

Claim:
A portable LED lighting unit for providing a plurality of individually selectable colored beams, the lighting unit comprising: a housing; a power supply source carried by the housing; and a single multi-chip lamp source centered within the housing and operably configured to the power supply source, the multi-chip lamp source comprising: a substrate; at least one white light emitting diode (LED) chip operably configured to the substrate to emit a substantially white light beam; at least one red LED chip operably configured to the substrate to emit a substantially red light beam; at least one blue LED chip operably configured to the substrate to emit a substantially blue light beam; and at least one green LED chip operably configured to the substrate to emit a substantially green light beam; and wherein the at least one white LED chip, the at least one red LED chip, the at least one blue LED chip, and the at least one green LED chip are configured to be actuatable to create multiple colored light beams and the LED chips are positioned on the substrate such that an emitted light beam remains concentric without shifting regardless of the chip or chips emitting the light beam; and a lens on the substrate over the at least one white LED chip, the at least one red LED chip, the at least one green LED chip and the at least one blue LED chip to thereby encase each chip within the lens.
