Abstract
The invention discloses a projector. A reversible or slideable air guide unit is arranged at the air outlet of a channel on a cooling device at one side of a bulb to lead the cold air of the cooling device to be guided and blown to the upper half part of the bulb and simultaneously reduce the temperature difference between the top end and the bottom end of the bulb during the process of reducing the temperature of the bulb so as to prolong the service life of the bulb. When the project is arranged in a forward position or a reversible position, the air guide unit at the air outlet of the channel can turn over to the lower side of the air outlet of the channel with a force of gravity, or slide so as to form an upward incline in the channel near the air outlet so as to guide large-proportion air flow to constantly flow to the relative upper half part and top end of the bulb on the vertical direction and increase the heat radiation on the upper half part and top end of the bulb. The air guide unit is arranged at the air outlet of the channel in the projector and can guide the air flow to be blown to the upper half part of the bulb, reduce the temperature difference between the top end and the bottom end of the bulb and prolong the service life of the bulb.
