Electron Or Vacuum Tube (23) Patents (Class D13/180)
  • Patent number: 10879440
    Abstract: A light-emitting device includes a carrier with a first surface and a second surface opposite to the first surface; and a light-emitting unit disposed on the first surface and configured to emit a light toward but not passing through the first surface. When emitting the light, the light-emitting device has a first light intensity above the first surface, and a second light intensity under the second surface, a ratio of the first light intensity to the second light intensity is in a range of 2˜9.

  • Patent number: 10431568
    Abstract: Light emitting diode (LED) devices, components and systems are provided. LED devices include a submount with a plurality of LEDs disposed thereon. The LEDs mounted on a submount can be spaced apart at predetermined dimensions to control the gaps between each of the plurality of LEDs. By controlling the gaps between LEDs the optical output from the LED device can be optimized, including improving emission and/or color uniformity, minimizing or eliminating deadspots in the light emission, and/or minimizing or eliminating an optical cross. A phosphor layer can be disposed on the plurality of LEDs and between the LEDs in the gaps therebetween.

  • Patent number: 10396252
    Abstract: An LED package structure with multiple color temperatures includes a substrate, a circuit layer disposed on the substrate, a plurality of first LED chips and a plurality of second LED chips disposed on the circuit layer, and a light conversion layer disposed on the substrate and the circuit layer. The light conversion layer has a spiral surface arranged away from the substrate. The light conversion layer includes a first light conversion portion and a second light conversion portion arranged around a lateral side of the first light conversion portion. The color temperature of the first light conversion portion is different from that of the second light conversion portion. The first LED chips are embedded in the first light conversion portion, and the second LED chips are embedded in the second light conversion portion. Thus, the LED package structure provided by the instant disclosure has good production efficiency.
