Abstract

A light emitting diode (LED) warning signal light, the warning signal light comprising an array of light sources configured on a light support and in electrical communication with a controller and a power supply, battery, or other electrical source. The warning signal light provides various colored light signals for independent use or use by an emergency vehicle. These light signals may include a stationary light, strobe light, revolving light, an alternating light, a flashing light, and an oscillating light. Additionally, the warning signal light may be capable of displaying symbols, reverse characters, or arrows. Preferably, rotating and oscillating light signals are produced by sequentially illuminating columns of LED'"'"'s on a stationary light support. However, the warning signal light may also be rotated or oscillated via mechanical means. The warning signal light may also be transportable for easy connection to a stand such as a tripod for electrical connection to a power supply as a stand-alone warning signal. The controller may further be adapted to regulate or modulate the power intensity exposed to the illuminated LED'"'"'s to create a variable intensity light signal.

Claims

1. A warning signal light for use with a motorized vehicle, the warning signal light comprising:

a) a light support having a front side with a first visible exterior surface;

b) a plurality of light emitting diodes arranged about and attached to the first visible exterior surface; and

c) a controller in electric communication with the light emitting diodes, the controller constructed and arranged to activate the light emitting diodes thereby producing at least two different types of visually distinct warning light signals, wherein the controller provides variable illumination intensity to at least one of said visually distinct warning light signals by selectively providing modulated illumination to the light emitting diodes, said variable illumination intensity comprising non-constant luminosity, said light emitting diodes receiving power from a power source.

2. The warning signal light of claim 1, said warning signal light further comprising a back side having a second visible exterior surface having a plurality of light emitting diodes arranged about and attached to said second visible exterior surface.

3. The warning signal light of claim 2, wherein the controller independently controls the light emitting diodes on the first visible exterior surface and the second visible exterior surface for the provision of different warning light signals on the first visible exterior surface and the second visible exterior surface.

4. The warning signal light of claim 1, said plurality of light emitting diodes comprising light emitting diodes of at least two different colors.

5. The warning signal light of claim 4, the controller activating the light emitting diodes to create at least one of a single colored warning light signal and at least one of a multi-colored warning light signal.
