Abstract

A traffic light with automatic brightness adjustment is characterized in that a controller (1) and a photometric sensor (2) are arranged on the top surface of the traffic light shade. The controller (1) is a minimum single-chip microcomputer system, the photometric sensor (2) is connected with the input interface of the controller (1), and the traffic light (3) is connected with the output interface of the controller (1). The utility model has strong practicability, can automatically adjust the brightness, and ensures the safety of drivers driving and pedestrians crossing the road.

Description

Traffic lights with automatic brightness adjustment

technical field

The utility model relates to traffic facilities, in particular to a traffic light with automatic brightness adjustment.

Background technique

Though the traffic signal lamp that uses now also has shading cover, under strong sunlight, has influenced the brightness of traffic light, interferes driver and pedestrian's observation signal, causes very big danger and unnecessary loss to people's life and property. At the same time, although the use of ultra-high-brightness luminous tubes can avoid the interference of strong light, the use of full power around the clock will affect the service life of the luminous tubes, and it is not necessary to use full-power luminous tubes at night or in dark environments. The service life is not long and often changes traffic light, can bring inconvenience to traffic and driving equally.

Contents of the invention

The purpose of the utility model is to provide a traffic light whose brightness can be adjusted by itself according to the intensity of sunlight.

The traffic light with automatic brightness adjustment is characterized in that: a controller and a photometric sensor are arranged on the top surface of the traffic light hood, the controller is a minimum system of a single-chip microcomputer, the photometric sensor is connected with the input interface of the controller, and the traffic light Connect to the output interface of the controller.

The utility model has strong practicability, automatically adjusts brightness, delays the service life of traffic lights, and ensures the safety of drivers driving and pedestrians crossing the road.

Description of drawings

Fig. 1 is a structural representation of the utility model,

Fig. 2 is the electrical principle block diagram of the utility model.

In the figure: 1-controller, 2-photometric sensor, 3-traffic lights.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described: the traffic light that automatically adjusts brightness as shown in Fig. The device 1 is a minimum single-chip system, the photometric sensor 2 is connected with the input interface of the controller 1, and the traffic light 3 is connected with the output interface of the controller 1.

The principle can be seen from Figures 1 and 2: the photometric sensor 2 senses the intensity of sunlight, and transmits the sampled value to the controller 1, and the controller 1 then controls the brightness of the traffic light 3 according to the preset value. This not only ensures the safety of drivers and pedestrians, but also is very energy-saving and environmentally friendly. At the same time, the output power of traffic lights is reduced in the absence of strong sunlight, and the service life of traffic lights is delayed.

Claims (1)

1. A traffic light for automatically adjusting brightness is characterized in that: the top surface of the traffic light shading cover is provided with a controller (1) and a photometric sensor (2), and the controller (1) is a minimum system of a single-chip microcomputer, The photometric sensor (2) is connected with the input interface of the controller (1), and the traffic light (3) is connected with the output interface of the controller (1).
