Light emitting diode linear worklight

A light emitting diode (LED) linear worklight that converts point light into a linear light source is disclosed. The LED linear worklight comprises a linear light device and a power handle that connect together. The power handle holds batteries and comprises an LED module. The linear light device comprises a worklight body and a lens. A transparent light pipe is positioned in a reflecting holder inside the worklight body. The reflecting holder holds the light pipe and reflects light back into the light pipe. The LED module emits light into a light receiving end of the light pipe. The received light travels through the light pipe and is emitted from a light emitting surface of the light pipe. The reflecting holder reflects some of the light emitted from the light emitting surface and directs the light toward the lens and the light exits the worklight body.

Batwing light beam distribution using directional optics

A luminaire is provided to redirect incidence light from one or more solid state light sources to a batwing distribution with both tunable peak angle and beam width. The peak angle is able to be tuned from 90 degree to 0 degree from the incidence direction with very high efficiency. The beam width is able to be tuned with either narrow beam angle solid state light sources for high efficiency or TIR lens or the optical properties of a reflector for versatility. Uniform illuminance distribution is thus achieved across a wide field with or without a prism or diffuser cover.
