PURPOSE: To provide a radiator which can be manufactured at low cost with high efficiency and a flat structure by providing a conductor path structure on a transparent mounting board, fixing a plurality of light emitting semiconductors connected to the conductor path structure on the mounting board by planar arrangement and surrounding each semiconductor by a reflector. CONSTITUTION: A conductor path structure 12 is provided on a transparent mounting board 2, a plurality of light emitting semiconductors 1 connected to the conductor path structure 12 are provided by planar arrangement on the mounting board 2, each semiconductor 1 is surrounded by a reflector 3, and light component emitted from the semiconductor 1 to the reflector 3 is reflected through the mounting board 2. For instance, the conductor path 12 is mounted on the transparent mounting board 2, the semiconductor 1 is adhered on the mounting board 2 and is connected to the conductor path 12 by bonding wire 7. Then, plastic molding material is injected to a mold to manufacture the reflector 3a so as to permit each semiconductor 1 to exist at the local point of a parabola-shaped plastic body 5, and after hardening, the surface 6 is coated with high reflectivity material. |
