Easy-to-adjust digital projection lamp

Abstract

The invention discloses an easy-to-adjust digital projection lamp comprising a bulb, a translation module and a lifting module. Protective sleeves are disposed on both sides of the bulb and are filledwith sponge cushion layers. The right side of the bulb is provided with a screw stud fixedly connected to the bulb. The right side of the screw stud is provided with a lamp holder. A thread groove isdisposed on the inner side of the lamp holder. The translation module comprises a slide rail, a slide block and clamping blocks. The slide block is mounted on the slide rail. The top and the bottom of the slide block are provided with the clamping blocks. A crossbar is arranged between the clamping blocks. The clamping blocks are fixedly connected with the crossbar by bolts. The lifting module comprises a hydraulic motor and a hydraulic rod which are in transmission connection. The top of the hydraulic rod is equipped with a rotating shaft. The easy-to-adjust digital projection lamp can finely adjust the bulb in both vertical and horizontal directions very conveniently, is not required to be moved entirely, and has good practicability. In addition, a cooling fan is installed to improve anoverall cooling effect.

Description

technical field [0001] The invention relates to the technical field of digital projection lamps, in particular to an adjustable digital projection lamp. Background technique [0002] The spherical xenon lamp used in the movie projector is an ultra-high-voltage short-arc xenon lamp. The xenon lamp is a point light source. A continuous spectrum from ultraviolet light to visible light, which is very close to sunlight (6000K). With the long-term use of the movie projector, the projection position of the lens may be shifted due to the influence of the external environment. At this time, the lens of the movie projector must be adjusted. However, the lens of the existing equipment movie projector cannot be moved. Equipment, and the overall volume of the equipment is relatively heavy, which is quite inconvenient to use. [0003] Therefore, how to design a digital projection lamp that is easy to adjust has become a problem that we need to solve at present. Contents of the inventi...

Problems solved by technology

[0004] The purpose of the present invention is to provide a digital projection lamp that is easy to adjust to solve the problem that the projection position of the lens may be shifted due to the influence of the external environment as the movie projector is used for a long time in the above background technology. Adjust the lens of the movie projector, but the lens of the existing equipment movie projector cannot be moved, only the device can be moved, and the overall volume of the device is relatively heavy, which is quite inconvenient to use
