  (B) Theft prevention can be achieved by detecting a temperature change by the detection warning device, passing the temperature change to the red light warning light and the buzzer, turning on the red light warning light and sounding the buzzer.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
First, FIG. 1 to FIG. 3 will be referred to. The drawings are only for explaining the present invention, and the present invention is not limited to these structures.

  As shown in FIG. 1, a lighting device for a refrigerated freezer box according to an embodiment of the present invention includes a detection warning device 1, a first manual switch 2, a turning switch 3, an internal circuit 4, and an AC power source 5. Including. The detection warning device 1 is connected between the internal circuit 4 and the AC power supply 5. In this embodiment, the detection warning device 1 includes a thermal sensor 11, a controller 12, an auxiliary circuit 13, and a second circuit. A manual switch 14, a buzzer 15, and a red light warning lamp 16 are included. In the auxiliary circuit 13, the controller 12, the red light warning lamp 16 and the buzzer 15 are connected in parallel. In this embodiment, the controller 12 is an electromagnetic contactor, and the red light warning lamp 16 is a buzzer. 15 is controlled by the second manual switch 14 after being connected in parallel. In this embodiment, the first manual switch 2 is a fuseless switch, the second manual switch 14 is a single throw switch, and the fuseless switch has an overcurrent protection device. In the present embodiment, the internal circuit 4 includes an in-box illumination line 41, an out-box illumination line 42, and a control line 43. The power supply end 51 of the AC power supply 5 is connected to the turning switch 3, and the turning switch 3 is connected to the in-box lighting line 41 and the outside lighting line 42 by the internal circuit 4, and the in-box lighting line 41 is the first. The first manual switch 2 is connected to the manual switch 2 and is installed at the intersection of the box illumination line 41 and the control line 43. The control line 43 is connected to the other contact of the magnetic contactor, and the control line 43 is connected in series with the in-box illumination line 41, so that the in-box illumination line 41 is in parallel with the out-of-box illumination line 42. Connect to the ground terminal 52 of the AC power supply 5.

  As shown in FIG. 1, the operator turns on the turning switch 3 by a manual method as shown in FIG. 1, and in this embodiment, the turning switch 3 has a two-stage design. When this is done, it is in electrical communication with the out-of-box illumination line 42, so that the out-of-box illumination device 421 is turned on, starts lighting, and then turns to the second-stage switch to connect with the in-box illumination line 41. Therefore, the in-box lighting device 421 is turned on and lighting is started. Further, by turning on or off the in-box illumination line 41 manually by the first manual switch 2, the on-off of the in-box illumination device 411 can be controlled.

  From the viewpoint of energy saving, as shown in FIG. 2, the first manual switch 2 is turned off. At this time, the power of the heat sensor 11 is supplied to the auxiliary circuit 13, and the in-box illumination device 411 is controlled. When the consumer is in proximity to the refrigerated freezer box controlled by the line 43, the thermal sensor 11 detects a change in temperature and transmits a signal to the controller 12, whereby the coil of the magnetic contactor is magnetic. , The main contacts R and U become conductive, and the in-box illumination device 411 is turned on. On the contrary, when the consumer leaves, the thermal sensor 11 starts counting time, and if the consumer does not come close for a predetermined time, the thermal sensor 11 cannot detect a temperature change and outputs it to the controller 12. By stopping the signal, the magnetism of the coil of the magnetic contactor disappears, the main contacts R and U are disconnected, and the in-box illumination device 411 is also turned off. By the above operation, the on / off state of the in-box lighting line 41 is automatically controlled, so that the purpose of energy saving can be achieved and the electricity cost can be reduced.

Further, when the sales floor is closed, the turning switch 3 and the first manual switch 2 are simultaneously turned off, and the second manual switch 14 is turned on. As shown in FIG. Sometimes, the thermal sensor 11 detects a change in temperature and transmits a signal to the buzzer 15 via the auxiliary circuit 13. At this time, the red light warning lamp 16 is turned on and the buzzer 15 also starts to sound. As a result, the suspicious person escapes by surprise, so that the anti-theft effect can be achieved.
Of course, the present invention has various other embodiments. For example, the thermal sensor can be connected to another power source as shown by a broken line in FIGS.
