  • Light emitting device having protection element and method of manufacturing the light emitting device
    Publication number: 20070030611
    Abstract: A light emitting device having a monolithic protection element and a method of fabricating the light emitting device are provided. The light emitting device includes: a light emitter having a cathode and an anode; and the resistive protection element connected to the light emitter in parallel through the cathode and the anode. Here, a resistance Rs of the resistive protection element has a value between a forward resistance Rf and a reverse resistance Rr of a current of the light emitter.

  • LED device having diffuse reflective surface
    Publication number: 20060170335
    Abstract: A LED device is provided having a diffuse reflective surface which includes an LED chip emitting light, a reflector cup having the LED chip arranged at a bottom surface thereof and having an angled surface which diffusely reflects the light emitted by the LED chip, and a light conversion material provided in the reflector cup for converting the light emitted by the LED chip into visible light rays. The light-conversion material is spatially separated from the LED chip by a length equal or greater than the maximum length of the LED chip.
