ABSTRACT:
A light-emitting unit containing a substrate and light emitting diodes (LEDs) is housed inside a casing constituted by a first member and a second member which are joined together. The second member has a projecting piece which is inserted to the first member, and inside the projecting piece a passage is formed. When silicone is injected through an injection opening from an injector, the silicone starting from the projecting piece flows through in the order of the passage, first-member side space, connecting passage and second-member side space and it finally overflows from a discharge opening. By implementing this structure and process, the air or air bubbles inside the light-emitting unit is pushed outside completely.
