Abstract

The invention refers to a projector and method for cooling lamps installed in the projector. The projector includes a plurality of lamps serving as light sources, the lamps being arranged next to each other, and a single exhaust fan disposed adjacent to the lamps, the exhaust fan discharging air around the lamps.

Description

technical field [0001] The present invention relates to a projector and a method for cooling a light bulb installed in the projector. Background technique [0002] A projector is a display device for projecting images and includes a high-brightness light bulb as a light source. The light, for example, passes through a liquid crystal panel and is directed toward a screen or the like. A so-called two-bulb type projector is an example of a projector in the prior art, which has two bulbs. There are two types of dual-lamp projectors, namely: a dual-lamp projector in which both lamps are turned on at the same time to increase brightness, and a dual-lamp projector in which only one of the two bulbs is usually turned on and the other is left as a spare dual lamp projectors. [0003] When a lamp installed in a projector is turned on, the lamp becomes hot. Therefore, the temperature of the lamp and the space inside the projector will rise. Therefore, a cooling system including an...
