  • Patent number: 8360620
    Abstract: An LED recessed lighting fixture which includes a multiplicity of LED boards which have a multiplicity of LEDs thereon, the LED boards affixed to a heat sink to dissipate the heat generated from the LEDs. The LED boards are shrouded by a diffuser so that light from the LEDs shining through the diffuser mimics a fluorescent light. The fixture incorporates at least one reflector into the fixture so that some of the illumination from the LEDs will be reflected off the reflector after it has passed through the diffuser. An access door in the top of the fixture so that access to a driver retained within the fixtures can be provided from the top of the fixture. An access door in the top of the fixture so that access to an emergency battery retained within the fixture can be provided from the top of the fixture.

  • Patent number: 8344397
    Abstract: A solid state light sheet and method of fabricating the sheet are disclosed. In one embodiment, bare LED chips have top and bottom electrodes, where the bottom electrode is a large reflective electrode. The bottom electrodes of an array of LEDs (e.g., 500 LEDs) are bonded to an array of electrodes formed on a flexible bottom substrate. Conductive traces are formed on the bottom substrate connected to the electrodes. A transparent top substrate is then formed over the bottom substrate. Various ways to connect the LEDs in series are described along with many embodiments. In one method, the top substrate contains a conductor pattern that connects to LED electrodes and conductors on the bottom substrate.

  • Patent number: 8287144
    Abstract: The present invention relates to LED bar modules where the LED groups are placed at a pixel board. The present invention further concerns a method for calibration of LEDs. It is the object of the invention to achieve a highly efficient LED bar for generating a bar of light. A further object of the invention is to store calibration data for each LED both electrically and mechanically close to the actual LED. Preferably, the main printed circuit is placed inside a heat conductive tube, where the pixel board is placed outside the heat conductive tube in a longitudinal recess, where the main printed circuit is placed inside an isolation cover. Hereby, it is achieved that the LEDs are placed on the outside of the tube in a way where heat generated from the LEDs is conducted downwards to the tube. Inside the tube, the rest of the power electronics and also the light controlling electronics are placed.

  • Patent number: 8272756
    Abstract: A lighting system comprises a row of light emitting diodes (“LEDs”) receiving electricity and producing light and heat. The row of LEDs can be located in a channel or a groove of a piece of material, such as an aluminum extrusion or a bent piece of metal. The channel can have an optically reflective lining, for example, providing either diffuse or specular reflection. Accordingly, the channel can reflect light emitted by the LEDs. The piece of material can also include a heat sink for transferring heat from the LEDs to air via convection or air flow. The heat sink can comprise fins or protrusions that facilitate convection.
