Abstract
An electric discharge lamp device prevents a temperature rise in the circuit device when an electric discharge lamp ( ) is operated without the use of a high voltage wire and a high voltage connector. The electric discharge lamp device includes a reflecting member ( ) and a circuit device ( ) that is directly connected with the electric discharge lamp ( ) without using a high voltage wire. The distance between the reflecting member ( ) and the circuit device ( ) is set at a value not less than 6 mm. In operation, a beam of light emitted from the electric discharge lamp ( ) is reflected forward by a concave reflecting face of the reflecting member ( ).
