Abstract
A light source is composed of a discharge lamp, a resistor and a reflector container. The discharge lamp is provided as a source of light. The resistor increases a resistance in elevation of a temperature thereof, and reduces the resistance in lowering of the temperature thereof. The reflector container is a constituent element to which the discharge lamp and the resistor are attached. Additionally, the resistor is caused to heat an outer surface of the reflector container in accordance with elevation of a temperature of the discharge lamp in activation of lighting of the discharge lamp.
