Abstract

The embodiment of the invention discloses projection equipment and a projection lens and a projection lighting effect device thereof. The projection light effect device comprises a shell and a light effect assembly. The shell is used for containing a lens assembly and a light effect assembly, the light effect assembly is used for enabling projection to form a preset outline and/or generate a preset light effect, and the light effect assembly is movably connected with the shell and located on the light-in side and/or the light-out side of the lens assembly so that the light effect assembly can be switched in a light path and outside the light path. Therefore, the adjustment of the display effects such as the format and the light effect of the projected picture is realized.

Description

technical field [0001] The present disclosure relates to the display field, in particular to a projection device, a projection lens and a projection light effect device. Background technique [0002] With the rapid development of projection lenses, projectors and projection laser TVs have been gradually accepted by users and widely used in family, education, and business. In order to meet the market's demand for projection pictures, variable apertures have been gradually applied to projection light effect devices. The main function of the current projection light effect device is to adjust the brightness and contrast of the picture, but not to adjust the brightness of the picture. Frame, light effect and other display effects. Contents of the invention [0003] Embodiments of the present disclosure provide a projection device, its projection lens, and a projection light effect device, which can solve the technical problem that the projection light effect device in the pri...
