Embodiment 1
[0034] A light control device, used to automatically control the turning on or off of lights in a controlled area, including: a sensing device, connected to a switch circuit signal, used to detect whether there is a human body moving and / or staying in the controlled area, and if there is , an instruction to turn on the lamp is sent to the switch circuit, and if not, an instruction to turn off the lamp is sent to the switch circuit; the switch circuit is used to turn on or off the power of the lamp.
[0035] A lighting control method, comprising the following steps:
[0036] S1. The sensing device senses whether the human body enters the controlled area. If the sensing device senses that a human body enters the controlled area, it outputs a signal to the switch circuit. In the control area, there is no signal output, the lamp remains in the off state, the sensing device returns to the initial state and enters S1 again.
[0037] When the human body enters the controlled area, t...
Embodiment 2
[0039] The rest are the same as in Embodiment 1, the difference is that the sensing device includes a trigger sensor and an activity sensor, the trigger sensor is used to sense whether a human body enters the controlled area, and the activity sensor is used to sense whether a human body moves in the controlled area and / or stay. When the trigger sensor detects that a human body enters the controlled area, it sends an instruction to the switch circuit to turn on the lamp, and sends a working order to the activity sensor to make the activity sensor start to work. If no human body is detected to enter the controlled area, The switching circuit remains open, and the activity sensor remains in a de-energized or standby state.
[0040] After the activity sensor is turned on, it senses whether there is a human body moving and / or staying in the controlled area. If it senses that there is a human body in the controlled area, it sends a signal to the switch circuit so that the switch cir...
Embodiment 3
[0045] The rest is the same as Embodiment 2, except that the activity sensor is provided with a timer, which is used to set the time interval for detecting whether there is a human body moving and / or staying in the controlled area each time the activity sensor is activated.
[0046] A lighting control method, comprising the following steps:
[0047] S1. The trigger sensor starts to work, and senses whether the human body enters the controlled area. If the trigger sensor senses that a human body enters the controlled area, it outputs a signal to the switch circuit. The switch circuit connects the lamp, the light turns on, and the trigger sensor sends The activity sensor sends out a work command and enters S2; if the trigger sensor does not sense that the human body enters the controlled area, there will be no signal output, the lamp remains in the off-circuit state, and the trigger sensor remains in the working state;
[0048] S2. The activity sensor starts to work, and senses ...
