ABSTRACT:
A lighting device controls power to a discharge lamp according to the temperature detected by a lamp sensor, which detects temperature around the discharge lamp. The discharge lamp has an arc tube and an outer bulb between which an airtight space is defined. Therefore, the lamp can be actuated without reduction in luminosity even at low temperatures. Also, the lamp luminosity rises quickly.
