Abstract
A light-emitting diode (LED) therapeutic apparatus includes a body portion formed of a light-weight resin material into a rectangular housing; a printed circuit board including a plurality of LEDs having different emission colors mounted linearly in a plurality of rows at required intervals; a thermal radiating plate provided with a plurality of thermal radiating studs formed of a light-weight thermally conductive material; and a transparent plate mounted on an opening surface of the body portion. The thermal radiating plate is mounted in tight contact in the body portion, and the printed circuit board is mounted in tight contact with the heat radiating studs. The heat generated by the LEDs is radiated from the surface of the body portion via the thermal radiating plate from the thermal radiating studs. The LEDs may be maintained to a junction allowable temperature or lower so that a long life span without noise is achieved.
