Abstract:
An image display apparatus, comprising:a cabinet, said cabinet accommodating therein: a discharge lamp; an ignitor module which applies a high voltage to said discharge lamp for igniting the same; a lighting device which is connected to said ignitor module and applies a discharging voltage to said discharge lamp so as to keep said discharge lamp turned on; a signal processing unit providing an image signal in accordance with an input signal; an image display which, in response to said image signal from said signal processing unit, produces an image to be projected by use of a light of said discharge lamp; and a power supply supplying electric power to said ignitor module, said lighting device, said signal processing unit, and said image display; wherein said power supply provides a voltage power to said ignitor module through said lighting device, said ignitor module including a transformer which boosts said voltage power into a high voltage, and including a high voltage generating circuit which applies to said discharge lamp said high voltage, said lighting device generating a voltage from said voltage power, after said discharge lamp is ignited, for keeping said discharge lamp turned on; said ignitor module being physically separated from said power supply as well as from said lighting device, said cabinet accommodating said ignitor module within a first interior space close to said discharge lamp, and accommodating signal processing unit, said power supply and said lighting device as being separated from said ignitor module within a second interior space opposite from said first interior space, a lamp house being provided to be detachable from said cabinet, said lamp house having a lamp house interior space separated by a partition into two storage spaces, one for receiving said discharge lamp, and the other for receiving said high voltage generating circuit.
