Abstract

A light emitting diode (LED) warning signal light bar is disclosed. The warning signal light bar includes a controller for generating a plurality of observable light signals. The controller may regulate the illumination of LED'"'"'s to a desired pattern, sequence, and/or combination of simultaneous and/or individual light signals. The warning signal light bar includes a support frame which is adapted to receivingly hold an LED light source assembly. A plurality of light directors are positioned proximate to the LED Light sources which in conjunction with the cover function to direct and focus the light emitted from the LED'"'"'s in a desired direction or area.

Claims

1. A warning signal light bar comprising:

a) a support having a front and a rear;

b) a plurality of light emitting diode assemblies having light emitting diodes engaged to said front and to said rear, said light emitting diodes receiving power from a power source; and

c) a controller in electric communication with said light emitting diodes, the controller constructed and arranged to activate said light emitting diodes to produce at least two different types of warning light signals in at least one combination.

2. The warning signal light bar according to claim 1 further comprising a base having an internal enclosure and a circuit board having said controller positioned in said internal enclosure.

3. The warning signal light bar according to claim 2, said support further comprising opposite ends and an end cap assembly engaged to each of said opposite ends.

4. The warning signal light bar according to claim 3, each of said light emitting diode assemblies comprising a housing, a support, said light emitting diodes engaged to said support, a light pipe, and a cover.

5. The warning signal light bar according to claim 4, said cover comprising a plurality of light spreaders.
