A focus pluggable interface control device includes a sensor, a lens covered on the periphery of the sensor and a mounting plug electrically connected to external lamps. Optical signals passing through the lens to be focused is transmitted to the sensor. The lens is configured to collect control information of light types transmitted to the sensor in order to increase sensitivity of the sensor to receive the control information and response speed of the control information, and also expand sensing range of the sensor so as to improve user's experience. The sensor is electrically connected to the external lamp via the mounting plug so that the focus pluggable interface control device can be conveniently replaced, disassembled or installed without needing additional wires, thereby the cost of replacing the control device can be reduced.

A first light source illuminates a first region. A second light source is configured to provide lower luminance than that of the first light source. The second light source illuminates a second region that overlaps the first region, and that has a larger area than that of the first region. A lighting circuit drives the first light source and the second light source according to a common lighting instruction. The lighting circuit gradually turns on the first light source and the second light source with different gradual changing time periods in response to the lighting instruction.
