technical field

The utility model belongs to the technical field of switches, in particular to an illumination control device.

Background technique

In public indoor places such as canteens, gymnasiums, and classrooms, it is sometimes necessary to change the correspondence between wall switches and corresponding lights in order to save energy. For example, it is common to use a wall switch to control a row or a column of lights in classrooms, but when there are few people in the classroom, it is suitable for a wall switch to control several adjacent lights arranged in a rectangular shape, so as to avoid crowded classrooms. When it is rare, it is still necessary to turn on several rows or rows of lighting lamps to save energy. For gymnasiums, canteens, etc., it is common to use a wall switch to control the lights in a large area, but in the daytime with sufficient light, it is suitable to use a wall switch to control only a part of the lights arranged intermittently, so that it can be used according to the current outdoor lighting. Light conditions Turn on part or all of the lights, that is, turn on a wall switch, and the corresponding area is in the weakest fill light mode; the more wall switches turned on, the stronger the fill light intensity.

Because in the construction of lighting projects, for the convenience of wiring, the construction unit often adopts the aforementioned method of controlling a row or a row of lights with a switch, which cannot meet the needs of users for the brightness of light sources in different situations. Renovation of lighting in indoor places often requires major adjustments to wiring.
