The number of LEDs which match the lighting properties is mounted on one side of a substrate. Light is emitted from both sides of a double-faced LED module by using two substrates in parallel. An insulator and a heat conductor are fitted between the two substrates and are integrated. An angle between the emission surface of the LED module and a flat reflector is determined and used according to necessary lighting properties by attaching one side of the flat reflector on each of both upper sides of the integrated LED module. Heat due to the emission of the LED is discharged to the air through a heat radiator outside an external case of a lighting device by the heat conductor. |
