ABSTRACT:
A Light Emitting Diode (LED) indicator that more efficiently dissipates heat generated by LEDs and other circuit components is provided. The LED indicator includes a housing and a printed circuit board contained within the housing. The printed circuit board includes first and second sides with two or more LEDs attached to the first and second sides of the printed circuit board and a regulating circuit for regulating current supplied to the LEDs. The regulating circuit includes a linear voltage regulator. The printed circuit board includes first and second thermal dissipation sections. The first thermal dissipation section is thermally connected with the two or more LEDs and the second thermal dissipation section is thermally connected with the linear voltage regulator. The housing is at least partially lined with a plurality of reflectors for reflecting light generated by the LEDs through a lens.
