  • Patent number: 7452099
    Abstract: The present invention provides a light device comprised of a body, a handle, a user interface, and a positionable arm that is structured to pivotally support a lighting element assembly. The light device may be configured to be portable and carried or otherwise manipulated by a user grasping the handle. In one embodiment, the body of the light device defines first and second support surfaces that are structured to stably support the weight of the light device in first and second illumination positions, respectively.

  • Patent number: 7355349
    Abstract: The present invention transforms existing electrical wall outlets into an emergency lighting system for homes, hospitals, hotels, nursing homes and businesses. The lighting device, designed as a replacement electrical wall outlet or receptacle, simply plugs into an existing dual outlet after removal of its faceplate. The lighting device continues to function as an electrical outlet, however, also comprises a local power source such as a constant charge lithium ion battery; a motion sensor for initiating a low level of lighting for darkened room or corridor transit; a power sensor for activating a high level of light when electrical service is disrupted, thereby broadcasting a wash of light over an otherwise darkened room or corridor; and a photoelectric cell which detects daylight or otherwise provided lighting of the room or corridor and thereby prevent unnecessary power usage.

  • Patent number: 6986589
    Abstract: The present invention includes an emergency lighting device comprising, at least one light emitting diode (LED), a local energy source such as a lithium ion battery, a control circuit in electric communication with the at least one LED and further sensing a main power supply, and a reflector for broadcasting light produced by the LED to designated areas. In particular, the present invention transforms existing fluorescent, incandescent or halogen light fixtures into emergency lighting systems for homes, hospitals, hotels, nursing homes and businesses. The device includes a power sensor for triggering the control circuit to engage the LEDs when electrical service is disrupted, thereby broadcasting a wash of light over an otherwise darkened room or corridor.

  • Patent number: 6752515
    Abstract: An improved emergency or interim lighting device and associated methods for providing emergency or temporal lighting. The device satisfies the need for an electrochemical lighting system capable of providing prolonged illumination over the life of the power unit. The device benefits from the use of LEDs as the illumination source, which provide optimum lumen output with considerably less power consumption than conventional incandescent lighting devices. By providing for a unique combination of diode arrangement and parabolic reflector the directional limitations of conventional LED lighting devices are overcome and wide area illumination coverage is provided. Additionally a multi-level lighting scheme provides for a means of identifying the device during electrical power outage and providing multiple levels of lighting intensity.
