  • Publication number: 20170248753
    Abstract: 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.

  • Publication number: 20170248279
    Abstract: A stacked pipe light emitting diode lighting fixture with uniform and uninterrupted emitted light is disclosed. The stacked pipe light emitting diode lighting fixture comprises a plurality of transparent light pipes disposed in a housing. A light emitting diode module is connected to a light receiving end of each light pipe. The light pipes and connected light emitting diode modules are positioned so that light reflecting ends of the light pipes overlap the light emitting diode modules. As a result, the emitted light is uniform in intensity and uninterrupted for one end of the stacked pipe light emitting diode lighting fixture to the other end of the stacked pipe light emitting diode lighting fixture.

  • Publication number: 20170248752
    Abstract: A portable linear worklight for converting point light into a linear light source is disclosed. The portable linear worklight comprises a worklight body and a lens. A transparent light pipe is positioned between an upper reflector and a lower reflector inside the worklight body. The lower reflector holds the light pipe and reflects light back into the light pipe. A light emitting diode in a battery housing emits light into a light receiving end of the light pipe. The received light travels trough the light pipe and is emitted from a light emitting surface of the light pipe. The upper reflector 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.
