Abstract

The invention relates to a projection light machine and projection equipment. A light machine shell of the projection light machine comprises a bottom shell, a first cover plate, a second cover plate and a heat dissipation light blocking assembly, the bottom shell is provided with a light source cavity and a lens set cavity with the ends connected, the side wall of the lens set cavity is externally connected with a main body lens flange, the bottom of the lens set cavity is provided with a hollow structure for the heat dissipation light blocking assembly to penetrate through, connecting terminals of the main body lens flange and the light source module extend out of the bottom shell, and the main body lens flange is provided with a mounting groove; the light source cavity extends from the lens group cavity to one side where the main body lens flange is located; the first cover plate covers the lens group cavity, and the second cover plate covers the light source cavity; a galvanometer module is mounted in the mounting groove; a lens module is mounted on the main body lens flange; a light beam adjusting module is mounted in the lens group cavity and comprises a prism assembly, a fly-eye lens and a lens assembly; and the light source module is installed in the light source cavity. The size of the projection light machine can be reduced as much as possible, and the debugging efficiency is improved.

Description

technical field [0001] The invention relates to the field of projection technology, in particular to a projection light machine and projection equipment. Background technique [0002] Projection equipment is a device that projects images or videos onto curtains or walls. It is widely used in offices, schools, entertainment venues, etc., and gradually penetrates into people's daily life. In order to adapt to the convenience of life, miniaturization, Miniaturized projection equipment has gradually become an important development trend of projection display. The digital light processing (Digital Light Processing, DLP) projection display method has the characteristics of high brightness, high contrast, and high resolution. Combined with a new LED light source, it can realize a miniaturized portable micro-projection, satisfying people's desire for portable and free projection display. demand. [0003] The projection imaging quality of DLP projection equipment is closely related...
