[0004] The traditional clean workshop lamp design is controlled by a rocker switch, and the same loop lamp cannot exceed 25 lamps according to the specification, which means that a single rocker switch can control up to 25 lamps. However, the clean workshop is generally controlled according to the production line, and a production line has hundreds of lamps. If designed according to the traditional design, many rocker switches will be arranged at the door of the clean room, which will be inconvenient to use in the later stage, and the situation of all on or all off will occur, which is not energy-saving and causes trouble to the operation.

[0005] In addition to the rocker switch control in the traditional design, the circuit breaker in the lighting box can also be used for direct control, but the clean plate wall is thin, and the lighting box cannot be directly embedded in the clean plate wall, which will protrude from the clean plate during actual installation, resulting in many holes on the clean plate, which is not only not beautiful, but also difficult to ensure the cleanliness requirement.
