Some locomotives have been equipped with an automatic lighting control system that automatically controls the opening and closing of lights according to the brightness of the external environment. Referring to FIG. 1 , a conventional automatic lighting control system 1 includes a light source sensor 11 for detecting external brightness, a brightness level detected by the light source sensor 11 and a predetermined brightness level. The quasi-level comparison circuit 12, a drive circuit 13 electrically connected to the level comparison circuit 12, and a switch 14 electrically connected to the drive circuit 13 and controllably opening and closing a lamp 15 are provided. When the light source sensor 11 senses the external brightness and transmits a sensing brightness to the level comparison circuit 12, when the sensing brightness is less than the predetermined brightness, a first comparison signal is output and transmitted to the driving circuit 13 At this time, the driving circuit 13 transmits a turn-on driving signal to the switch 14, and the switch 14 immediately turns on the lamp 15. When the sensing brightness is greater than the predetermined brightness, a second comparison signal is output and transmitted to the driving circuit 13. At this time, the driving circuit 13 transmits a light-off driving signal to the switch. 14. The switch 14 immediately turns off the headlights 15. The locomotive can automatically sense the brightness of the surrounding environment and automatically turn on and off the lamp 15, so that the lamp 15 can be automatically turned on in the case of insufficient light, and can be automatically turned off in a bright place to avoid power waste.

However, the automatic lighting control system 1 is composed of many electronic components, such as resistors, capacitors, inductors, and transistors, and the circuit assembly is complicated and takes up space. Moreover, after the automatic lighting control system 1 is installed, the vehicle lamp 15 cannot be manually turned on or automatically turned on according to the user's needs, and if the predetermined brightness of the level comparison circuit 12 is to be adjusted, the internal circuit needs to be changed. Component design and replacement of internal electronic components, causing user confusion and inconvenience, still need to explore improvements.

Accordingly, it is an object of the present invention to provide an automatic opening and closing control method for an illumination device that can be adjusted in function settings.

Therefore, the automatic opening and closing control method of the lighting device of the present invention causes an illumination device to automatically open and close. The control method includes a starting step, a detecting step, a comparing step, a controlling step, and an adjusting step. The starting step is to activate an operating unit and enter an automatic lighting mode by an adjusting unit, and display a corresponding lighting symbol on a display unit. The detecting step is to detect an external brightness by using a light source sensor and send a pair of brightness information corresponding to the external brightness to an electronic chip unit. The comparing step is to use the electronic chip unit to have a predetermined brightness. When the external brightness is less than the predetermined brightness, a first comparison signal is output, and when the external brightness is greater than the predetermined brightness, a second comparison signal is output. . The The controlling step is that when a power supply circuit receives the first comparison signal, the power circuit turns on the lighting device. When the power circuit receives the second comparison signal, the power circuit turns off the lighting device. The adjusting step is performed after the control unit of the adjusting unit enters the adjusting mode in the starting step, and adjusts the size of the predetermined brightness of the electronic chip unit and displays a corresponding brightness signal on the display unit. .

The effect of the invention is that the adjustment unit can adjust the size of the predetermined brightness of the electronic chip unit, thereby controlling the timing of the illumination device being turned on and off, and can be adjusted according to the needs of the user, and is convenient and practical to use. Good, very in line with human considerations.
