LIGHT EMISSION BODY WITH DIFFUSION PART AND ITS MANUFACTURE

摘要

PURPOSE:To manufacture the light emission body which has the diffusion part with a beautiful light emission surface by forming an injection hole for a dispersant and an air vent in a reflecting surface of an outer shell body and setting reflecting surface not in parallel with each other. CONSTITUTION:A tape is stuck on the opening surface of the outer shell body 2 which serves as the light emission surface. The outer shell body 2 is held slantingly with the reflecting surface 2a where the injection hole and air vent 7 are formed up so that the air vent 7 is higher than the injection hole 8 and the opening side of the inside reflecting surface 2b is high; and the dispersant 3a is injected into the injection hole 8 as shown by an arrow 4. The injection is stopped when the dispersant 3a is charged up to the air vent 7 and this state is held until the injected dispersant 3a cakes. Consequently, neither an air bubble nor air bubble trace in the dispersant remains on the light emission surface at the time of the manufacture and the beautiful light emission surface is obtained.
