PURPOSE:To enable the high integration of an LED, and diversify the function as a light emitting optical part, and also, enlarge the application by molding a section that the light of a resin part transmits in a lens part, which functions as a lens. CONSTITUTION:When a current is applied to it through a printed circuit 5 and a bonding wire 6... from a power source, for example, two pieces of LED chips 5... fixed onto a board 4 emit lights. And, the light emitted from the LED chip 5... is projected to outside through a lens part 8, which is overlaid on the board 4 and besides colored in red, yellow, green, or the like. This way, for this light emitting optical part, one part of the resin part 3 for sealing the LED chip 5... is made into a lens part 8, so the high integration of the LED chip part becomes possible. Moreover, on the board, the LED chip 5... can be arranged in various shapes, so it can be applied to not only, for example, indication but also an optical switch, etc., and the application enlarges. |
