Abstract

The invention discloses a projection lamp focusing mechanism and a projection lamp, and belongs to the field of projection equipment. The projection lamp focusing mechanism comprises a base, an X-axisdriving mechanism arranged in the X-axis direction is installed on the base. An X-axis movable base is mounted at the output end of the X-axis driving mechanism; a Z-axis driving mechanism arranged in the Z-axis direction is installed on the X-axis movable base, a Z-axis movable base is installed at the output end of the Z-axis driving mechanism, a Y-axis driving mechanism arranged in the Y-axisdirection is installed on the Z-axis movable base, a Y-axis movable base is installed at the output end of the Y-axis driving mechanism, and a lamp holder is installed on the Y-axis movable base; theX axis, the Y axis and the Z axis form a space rectangular coordinate system; the X-axis driving mechanism, the Y-axis driving mechanism and the Z-axis driving mechanism are all linear driving mechanisms. The projection lamp focusing mechanism is simple in structure, reasonable in design and capable of efficiently and conveniently focusing.

Description

technical field [0001] The invention relates to the field of projection equipment, in particular to a projection lamp focusing mechanism and a projection lamp. Background technique [0002] Projector lamp, also known as projector, is a device that can project images or videos onto the screen. When it is used for general lighting, it can be widely used in outdoor lighting projects in homes, offices, schools and entertainment venues. At the same time It can also be used to create various lighting effects and project the required patterns. [0003] During the use of projection lamps, there is often a need to adjust the focus. Commonly used projection lamps are generally adjusted by adjusting the position of the lens to change the distance from the light source to achieve adjustment of the focal length. However, in the existing projection lamp technology, the structure for adjusting the position of the lens is relatively complicated, and the adjustment is relatively cumbersome....
