PURPOSE:To achieve the downsizing of luminous devices and simplify manufacturing processes by positioning a circuit board above light emitting boards, and thus placing them in a case. CONSTITUTION:Light-emitting boards 2 composed of glass-epoxy resin, mounted with LED elements 1, are housed in a box-shaped case 3a of modified P.P.O. resin in a way that they are placed on supports 3b with the LED elements 1 facing downward. The position correcting hole 9a formed in a circuit board 9 mounted with a pluality of electronic parts 8' is fitted onto a position correcting pin 4, and the circuit board 9 is thereby brought into contact with the stepped lower face 4a of the position correcting pin 4. Thus the light- emitting boards 2 and the circuit board 9 are placed together in the case 3, and they are thereby integrated with each other. This makes it possible to downsize the device. It also makes unnecessary processes wherein a light- emitting device is mounted on a circuit board 9, which makes possible simplifying the manufacturing process. |
