Embodiment 1
[0074] refer to figure 1 As shown, a light anti-theft device includes: an executive component 111, a controller and a light sensor 9, the executive component is used to turn on or off the light source; the controller, the controller controls the action of the executive component; the light sensor, the light The sensor collects the bright and dark signals of the environment, and feeds back the signal to the controller; the executive component can be directly set in the power supply circuit of the light source to realize direct control.
[0075] In order to achieve the effect of automatically switching the light source, the steps for the controller to control the action of the actuator are as follows:
[0076] Step 1) The light sensor collects the light and dark signals of the environment;
[0077] Step 2) When the light sensor detects that the environment is dark, the feedback signal is sent to the controller, and the controller controls the executive component to turn on the ...
Embodiment 2
[0084] Embodiment 2 Compared with Embodiment 1, in this embodiment, since the light source in the existing family is basically a lamp, and the switch has been fixed on the wall, in order to adapt to the above situation and improve the application range of the anti-theft device, refer to figure 2 As shown, the executive component performs a switch action, and the switch action is to turn on or turn off the light source, so as to ensure that the anti-theft device can be installed additionally.
[0085] The above-mentioned executive assembly includes a motor 5, a switch plate 1 and a power output mechanism 2. The power output mechanism is a reduction gear set. The gear set is meshed with the teeth; therefore, the tooth plate can achieve the effect of rotation along the shaft and the center. When the motor rotates, the reduction gear set can drive the teeth to rotate. The teeth are set on the tooth plate, so the tooth plate Drive the entire switch plate to rotate, so when the mot...
Embodiment 3
[0089] refer to image 3 and Figure 4 As shown, the difference between the third embodiment and the second embodiment is that a fixed portion is provided on the housing bracket, and the fixed portion includes two transverse support beams 10 and two support feet 11 cooperating with the two transverse support beams, and the transverse support An insert 12 is fixedly arranged on the beam, and the insert is inserted in the gap between the panel of the switch and the installation part (body of wall), so that the transverse support beam can be fixed, and the two transverse support beams are respectively arranged on the upper part and the lower part of the panel, It is suitable for all switch panels with gaps. The surface of the support beam is provided with a guide groove 13, and the support leg is provided with a guide hook 14. The guide hook is set in the guide groove, and the two support legs are fixed on the shell bracket. Finally, it can ensure the structural stability of the...
