Abstract
A cabinet accommodates therein a discharge lamp 13, an ignitor module 7 applying a high voltage to the discharge lamp 13 for igniting the same, a lighting device 8A which is connected to the ignitor module and applies a discharging voltage to the discharge lamp so as to keep the discharge lamp turned on, a signal processing unit 9 providing an image signal in accordance with an input signal, an image display which, in response to the image signal from the signal processing unit, produces an image to be projected by use of a light of the discharge lamp 13, and a power supply supplying electric power to the above parts. At least a high voltage generating unit of the ignitor module 7 is arranged to be separated from the lighting device 8A and is disposed away from the signal processing unit 9 and close to the discharge lamp 13 for restraining malfunction of the signal processing unit.
