Problems solved by technology

[0002] Since the screen size of the projector can be flexibly adjusted by adjusting the distance between the projector and the projection screen, but if the distance is adjusted to be small, the projection light will be too concentrated, and the projection screen will be overly illuminated, which will give people a strong visual effect. Irritation, causing eye fatigue, dizziness, and even health problems such as retinal damage and detachment

Abstract

The present invention relates to a projector with adaptive illumination. The projector comprises a projector body; a distance detection device, a processor, a light source power controller, a light source, an image column module and an imaging lens are arranged in the projector body, wherein the distance detection device, the processor, the light source power controller, the light source, the image column module and the imaging lens are sequentially connected with one another, and the distance detection device and the imaging lens are arranged at the front part of the projector body. The projector is moderate in integral illumination; illumination on a projection curtain is consistent; and the projector is convenient to use.

Description

technical field [0001] The invention relates to a projection device, in particular to an adaptive illumination projection device. Background technique [0002] Since the screen size of the projector can be flexibly adjusted by adjusting the distance between the projector and the projection screen, but if the distance is adjusted to be small, the projected light will be too concentrated, and the projection screen will be overly illuminated, which will give people a strong visual effect. Irritation, causing eye fatigue, dizziness, and even retinal damage and detachment and other health problems. Contents of the invention [0003] Purpose of the invention: The purpose of the present invention is to overcome the deficiencies in the prior art and provide a projector with moderate overall illuminance, constant illuminance on the projection screen, and easy-to-use adaptive illuminance. [0004] Technical solution: In order to solve the above technical problems, a projector with ...
