Patent ID: 7893453

Claim:
A semiconductor light-emitting device comprising: a base board having at least one pair of electrodes configured to receive a power supply; at least one LED chip located adjacent the at least one pair of electrodes of the base board and including LED chip electrodes, and each of the LED chip electrodes being electrically connected to a respective electrode of the at least one pair of electrodes of the base board; a reflector including a cavity, the reflector being located adjacent the base board so as to enclose the at least one LED chip; a silicon resin configured with a soft silicon resin having a tacky surface to encapsulate the at least one LED chip, the silicon resin being disposed in the cavity of the reflector and having an opposed surface opposed to base board; and microparticles disposed on substantially the entire opposed surface of the silicon resin using the tacky surface of the silicon resin and disposed between and in contact with both the silicon resin and an outside atmosphere so as not to expose the silicon resin to the outside atmosphere.
