  • Patent number: 6254244
    Abstract: A controllable auto-heating type heat source is located at a periphery of a light source and light reflecting layers are placed between the light source and the controllable auto-heating type heat source. Therefore, use of a temperature detector and a control circuit in order to control the heat source are unnecessary, so that thermal runaway of the heat source is avoided. Further, the light reflecting layers reflect the light irradiated from the light source, so that the amount of the beam of light shielded by the heat source is decreased.
