The invention relates to a projection machine which comprises a light bulb and a light bulb cooling device, wherein the light bulb cooling device cools the light bulb from at least two directions. In the invention, the light bulb of the projection machine is cooled from at least two direction, the cooling points of the light bulb are increased, overall cooling can be carried out on the light bulb, the light bulb of the projection machine is cooled from two directions, cold airflow from side face exists at zenith of the light bulb along the air direction no matter the projection machine adopts any angles for projection, fully adequate and effective cooling is carried out on the zenith of the light bulb, the temperature of the light bulb is reduced, and a light wick of the light bulb normally works as the maximum temperature and the minimum temperature are in limited temperatures, thereby the service life of the light bulb is prolonged, and the quality of the projection machine is improved.
Description
【Technical field】 [0001] The invention relates to a projection display device, in particular to a projector and a cooling method for a bulb thereof. 【Background technique】 [0002] With the popularization of projectors, projectors are more and more widely used, and the traditional two modes of upright placement and ceiling placement of projectors can no longer meet the diverse needs of customers. Many projectors have launched a function that can project at any angle of 360 degrees to meet the needs of customers. [0003] Projector bulbs have different projection angles, and the highest point of the bulb temperature is also different. (The highest point of the bulb temperature is always in the direction of the line formed by the wick sphere and the center of the earth. below the sphere). When the projector is converted to different angles, the highest point of the bulb temperature changes accordingly. [0004] The traditional cooling system only cools the bulb from a singl...
