Abstract: A semiconductor light-emitting device and a method for manufacturing the same can include a soft silicon resin encapsulating an LED chip with a thin overcoat of microparticles located on the silicon resin to prevent dirt and dust from attaching to the silicon resin. The semiconductor light-emitting device can include a base board having at least one LED chip, a reflector fixed on the base board so as to enclose the LED chip, a soft silicon resin having a tacky surface disposed in the reflector, and an overcoat of microparticles on the silicon resin. Thus, manufacturing lead time can be reduced because the microparticles can attach to the silicon resin in a thin and single layer and a solidifying process for an extra layer on top of the silicon resin is not necessary. The overcoat of microparticles can prevent dirt and dust from attaching to the silicon resin, and can decrease optical variability in an inclined direction from an optical axis of the device.
