  • Patent number: 9964287
    Abstract: The invention discloses a LED support comprising an opaque housing. A mounting face for placing at least one LED chip is provided inside the housing. At least two light-exiting windows are provided on the housing so as to allow light emitted from the LED chip to emit outwards from the housing therethrough. The LED support enables a LED assembled with the LED support to emit light from at least two sides, thus light-emitting angle of LED is enlarged, and thereby application range of LED is widened. Meanwhile, with such LED support, the number of the light-exiting windows of the LED comprising the LED support is increased, thus the times by which light from the LED chip mounted on the LED support is reflected inside the LED support is decreased, and thereby light emission efficiency is improved significantly.

  • Patent number: 8960965
    Abstract: A lamp including the following elements is provided. A housing has an assembling opening and an electrical base on two ends thereof, wherein the housing has an inner wall and a portion of the inner wall adjacent to the assembling opening is an air-guiding wall. A cooling fan has a casing disposed at the assembling opening and forming an air channel, a fan wheel rotatably arranged in the air channel, and at least one partitioning board between the air-guiding wall and the air channel so as to define at least one first air-guiding opening and at least one second air-guiding opening. A light-emitting module is arranged in the housing and opposite to the fan wheel. Accordingly, the present lamp does not require forming any air inlet or air outlet on the housing, and thus provides a simplifier structure.

  • Patent number: 8956036
    Abstract: A light guide panel is disclosed. The panel comprises a plate for dispersing light and at least one light-emitting diode (LED) coupled to the plate for providing the dispersed light. When the panel is coupled to a keyboard, the at least one LED is under a portion of the keyboard such that when the at least one LED is illuminated, the light from the LED does not distract a user. Accordingly, by strategically placing LEDs within the panel and providing the LEDs under appropriate portions of the keyboard, the device utilizing the keyboard can be smaller than when a conventional light guide panel is utilized. In addition, a further improvement in illumination is provided when a mechanism is provided which reflects light escaping from the edges of the panel back into the panel.

  • Patent number: 8944618
    Abstract: An illumination module includes a plurality of Light Emitting Diodes (LEDs) and a light conversion sub-assembly mounted near but physically separated from the LEDs. The light conversion sub-assembly includes at least a portion that is a polytetrafluoroethylene (PTFE) material that also includes a wavelength converting material. Despite being less reflective than other materials that may be used in the light conversion sub-assembly, the PTFE material unexpectedly produces an increase in luminous output, compared to other more reflective materials, when the PTFE material includes a wavelength converting material.

  • Patent number: 8934248
    Abstract: A thermal dissipator includes an elongated laminar thermal transfer member having opposite sides, opposite ends and a longitudinal axis extending between those ends. The member has a thermal conductivity along its axis and in a first plane extending between its sides that is substantially greater than the thermal conductivity of the member in a second plane transverse to the first plane. A transverse heat sink structure contacts at least one side of the thermal transfer member along the length thereof, and extends from the thermal transfer member in a direction parallel to the first plane. A compression device compresses the thermal transfer member and the heat sink structure together to establish intimate thermal contact therebetween. Solid state lighting apparatus incorporating the dissipator is also disclosed.
