technical field

The invention relates to an intelligent high-definition light control device.

Background technique

At present, the curtain surface of generally known curtains usually has related materials such as cotton cloth, non-woven fabrics, nylon cloth, plastic cloth, bamboo weaving materials, etc., and there are many structures and styles of curtains. In order to meet the needs of the market, the design changes continuously, but the basic purpose of curtains is different. The purpose is to be able to block light and ensure privacy, but also to be able to control the appropriate light into the room, and the current curtains, whether they are hanging curtains, roller blinds, shutters or Roman blinds, etc., most of them are based on It is made of one-piece molding, and when used, the roller blind surface is combined with the retracting mechanism; thus, the curtain surface can be used to achieve shielding, partial light transmission and beautiful appearance by using the hanging and retracting of the retracting mechanism.
