Abstract

The invention provides a rotating type bulb base which comprises a mounting support, a rotating frame, a bulb fixing cover used for mounting a bulb and a radiating fan, and a driving device. The rotating frame is arranged on the mounting support. The bulb fixing cover is fixedly arranged on the rotating frame. The bulb fixing cover and the rotating frame form a rotating combination which is arranged on the mounting support in a rotating mode. The driving device is connected to the rotating combination and is used for driving the rotating combination to rotate. When the projection direction of the bulb needs to be changed, only by driving of the driving device, the rotating combination body can rotate by 360 degrees freely, accordingly, the bulb is driven to rotate to the needed angle position, meanwhile, the bulb is fixed on the bulb fixing cover, the radiating fan and the bulb arranged on the bulb fixing cover are fixed in arranged position, and therefore even if the projection direction of the bulb is changed, the radiating fan can carry out reasonable radiating at the positions where temperature is highest and lowest in the bulb. The invention further provides a projector with the rotating type bulb base.

Description

technical field [0001] The invention relates to the technical field of projectors, in particular to a rotary bulb base applied to a projector and a projector with the bulb base. Background technique [0002] At present, most ordinary projectors use high-pressure mercury lamps, and the service life of high-pressure mercury lamps is 2000-3000 hours, which meets the general work needs. However, the current projectors only support the use of upright and suspended ceilings. If these two states are changed, the service life of the high-pressure mercury lamp will decrease rapidly, and may not exceed 200 hours. This is because when the projector rotates, the highest and lowest temperature points inside the high-pressure mercury lamp are always at the top and bottom of the luminous sphere. If these two states are changed, the cold air of the cooling fan used to cool the high-pressure mercury lamp will not be reasonable. Blowing to the highest point and the lowest point of the temper...
