Light emitting diode indicator
First Claim
1. A Light Emitting Diode (LED) indicator comprising:
- a housing having a lens and opaque sides; and
a single printed circuit board contained within the housing approximately perpendicular to the lens and approximately parallel to one or more of the opaque sides, the printed circuit board having first and second sides, the printed circuit board including;
two or more LEDs attached to the first and second sides of the printed circuit board, when the two or more LEDs are activated they produce light that passes through the lens; and
one or more current regulators for regulating current supplied to the LEDs.

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.
