<p>The present invention provides an LED light source device for a medical astral lamp capable of having shadowless effects at the focal point of light on the affected area, preventing temperature increase, obtaining the same or greater brightness using a less amount of power, and enhancing heat dissipation efficiency of an LED light source, by reflecting light generated by the light source onto a reflector. The LED light source device for a medical astral lamp includes an appropriate number of LED light source units (200) in the housing (110) of an astral lamp and makes light emitted from each LED light source unit (200) to head for the center. The LED light source unit (200) includes: a support frame which supports the astral lamp (100) by being installed in the astral lamp (100) and includes a latching projection (211) inside; a reflector which is inserted and combined to the support frame (210) and reflects light from an LED light source element (220); heat dissipation members (240,240′) which are attached to the reflector (230) for the LED light source element (220) to be installed and has a heat dissipation function; and a diffused reflection filter (250) which is placed at the front of the heat dissipation member (240) and induces more shadowless effects at the focal point of light heading for the center.</p> |
