Description

Technical Field

[0001] This utility model relates to the field of wireless lighting in tunnels, specifically to an automatic adjustment device for wireless lighting in tunnels. Background Technology

[0002] A tunnel wireless lighting control system is an intelligent lighting management system based on wireless communication technology. It connects lighting equipment to control terminals and a smart lighting platform via a wireless network, enabling remote monitoring, intelligent control, and automated management of the lighting equipment. Compared to traditional wired lighting control systems, wireless lighting control systems offer significant advantages such as convenient installation, simple maintenance, and strong scalability, greatly improving the management efficiency and intelligence level of urban lighting. A Chinese patent (authorization announcement number CN 107257592A) discloses a tunnel wireless lighting automatic adjustment device and its method. In this patent, when construction workers need to change the horizontal lighting brightness, they turn a handwheel, causing the horizontal moving platform to move the lifting platform and transmitting coil horizontally. At this time, the receiving circuit current in the original transmitting coil magnetic field area decreases, resulting in a decrease in the brightness of the lights in that area. After the movement, the receiving circuit current in the transmitting coil magnetic field area increases, increasing the brightness of the lights in that area. However, this design involves complex brightness adjustment, and the lighting angle cannot be adjusted. Therefore, those skilled in the art have provided a tunnel wireless lighting automatic adjustment device to solve the problems mentioned in the background art. Utility Model Content

[0004] Preferably: a handle is installed on the top of the lighting lamp, the top of the handle is installed to the front end of the connecting shaft, and a spring and a top cylinder are installed sequentially at the rear end of the connecting shaft;

[0008] The technical effects and advantages of this utility model are as follows:

[0009] 1. After the power is turned on, the light intensity in the tunnel is reflected by the photosensitive element in the light sensor circuit board. The resistance or current of the element will change and be converted into an electrical signal. The photoresistor has a larger resistance in low light environment and a smaller resistance in high light environment. By monitoring the changes in tunnel light and feeding the signal back to the dimming controller to adjust the brightness of the lighting, it can provide a display effect or lighting that is more suitable for the current light conditions.

[0010] 2. When the tunnel is dimly lit, the light sensor circuit board sends a signal back to the actuator and motor. The actuator moves the fork, causing it to act on the top cylinder and shift outward. The lever, acting on the top cylinder, pushes the top block, causing the top of the top block to press against the inner wall of the turntable. The small-amplitude rotation of the motor shaft drives the turntable to rotate, which in turn drives the connecting shaft to rotate, causing the handle to rotate at a certain angle. This concentrates the light from the lighting lamp onto the middle area of ​​the tunnel, increasing the brightness of the lighting. Attached Figure Description

[0021] The working principle of this utility model is as follows:

[0022] In a tunnel wireless lighting automatic adjustment device, when the power is turned on, the light intensity in the tunnel is reacted by the photosensitive element in the light sensor circuit board 1. The resistance or current of the element changes and is converted into an electrical signal. The photosensitive resistor has a higher resistance in low light conditions and a lower resistance in high light conditions. By monitoring the changes in tunnel light and feeding the signal back to the dimming controller 2, the brightness of the lighting lamp 3 can be adjusted to provide a display effect or lighting more suitable for the current light conditions. When the brightness in the tunnel is low, the light sensor circuit board 1 feeds the signal back to the actuator 4 and the motor 9. The actuator 4 moves the fork 5, causing the fork 5 to act on the top cylinder 6 and shift outward. The lever 10 pushes the top block 8 by acting on the top cylinder 6, so that the top head 801 of the top block 8 hits the inner wall of the turntable 11. The small-amplitude rotation of the shaft 901 of the motor 9 drives the turntable 11 to rotate, thereby driving the connecting shaft 7 to rotate, so that the lever 301 rotates at a certain angle, so that the light of the lighting lamp 3 is concentrated on the middle area of ​​the tunnel, improving the brightness of the lighting.
