  • Patent number: 9797565
    Abstract: A light engine for a lighting fixture includes a bracket, with multiple mounting surfaces configured at different angles to form a substantially concave region, and a plurality of light emitting diode (LED) modules mounted to the multiple mounting surfaces to project an axis of a light beam from each of the plurality of LED modules along substantially a same illuminating plane. The light engine includes a first set of lenses with a first type of optical surface for focusing a first portion of the plurality of LED modules and a second set of lenses with a second type of optical surface, different than the first type, for focusing a second portion of the plurality of LED modules.

  • Patent number: 9791117
    Abstract: A processing unit in a dual-mode lighting fixture receives, via a light pipe of the lighting fixture, a test command signal from a remote control and initiates, based on the test command signal, testing for emergency condition lighting of the lighting fixture. The processing unit receives, via the light pipe, a control command signal from the remote control and controls, based on the control command signal, normal condition lighting of the lighting fixture. The processing unit also monitors feedback loops from a battery, a charger, or a set of LED lamps in the lighting fixture and presents, via the light pipe, a status color indication based on the monitored feedback.

  • Patent number: 9648767
    Abstract: A lighting equipment enclosure comprises a front plate assembly and a back plate assembly. The back plate assembly comprises a back plate including a partition that defines an area of the back plate, wherein the area includes a first access point and a second access point. The back plate assembly also comprises a snap electrical connector, a set of wires that extend from the snap electrical connector, and a partition cover that is attachable to the back plate, wherein when the partition cover is in a closed position, the partition cover covers a substantial portion of the area. The partition and the partition cover form a space in which electrical wires from independent power supplies may be attached to the sets of wires.

  • Patent number: 7226195
    Abstract: A compact and cost-efficient lamp assembly includes cold-cathode fluorescent lamps in a variety of edge-lit display sign applications specifically, in edge-lit emergency lighting signs. The lamp assembly includes in one self-contained module a lower housing unit and an upper housing unit shaped to cover the lower housing unit. The lower housing unit is divided into a lower frame and an upper frame disposed on top of the lower frame. The upper frame has at least two inverters disposed within. The lower frame is a parabolic shape reflector frame supporting at least two cathode lamps in line with the two inverters, each of which is connected to each lamp for providing high voltage to power up the lamps. Additionally, an edge-lit panel having a front and back side is disclosed in the present invention. The backside includes a semi-transparent frosted surface with a white opaque lamination glued on the frosted surface.
