Embodiment 1

[0016] figure 2 It is a schematic diagram of an embodiment of the energy-saving controller of the present invention. The first thyristor SCR1 and the second thyristor SCR2 are connected in anti-parallel and connected in series with the load to the mains power supply. The first thyristor SCR1 is triggered at the beginning of the positive half cycle of the mains power supply voltage, and the second thyristor SCR2 is triggered at the beginning of the negative half cycle, which is like a non-contact switch, allowing frequent operation, no arc, and long life. If the positive and negative half cycles trigger the first thyristor SCR1 and the second thyristor SCR2 with the same phase shift angle a, the effective value of the load voltage can change with the angle a to realize AC voltage regulation. The field programmable logic gate module controls the trigger to realize the AC voltage regulation of the thyristor in the main circuit, and completes the change of the AC voltage of the s...

Embodiment 2

[0018] When entering the tunnel and / or driving out of the tunnel, since the light intensity detector detects that the ambient light is very strong (day) and / or very weak (night), respectively input high voltage and / or low voltage to the digital signal processing unit, the digital signal The processing unit inputs high voltage and / or low voltage to the driver, and the driver adjusts the brightness of the adaptive-intensity street lamp installed at the tunnel entrance to be close to the ambient light; from both ends of the tunnel to the middle of the tunnel, the brightness of all adaptive-intensity street lamps is adjusted according to the ambient light With a soft transition, the street light intensity of the entire tunnel is no longer consistent, and the driver will not have a strong visual light intensity change reaction, which reduces the traffic accident rate.

Embodiment 3

[0020] The optional working wavelength range of LED is 850nm, 1310nm, 1490nm, CW-DM, 1550nm, DWDM; the enabling method is light sensor start, passive light start, light and sound control combination technology, light sensor mechanical integration module and / or optional technology choose.

Abstract

The invention relates to an intelligent traffic energy-saving street lamp capable of automatically adapting to the light intensity, which relates to an intelligent traffic lighting system, and aims to solve technical problems of electric energy waste, too high or too low light intensity, inability of automatically adapting to the light intensity of ambient light, short street lamp service life and the like of an existing traffic lighting device. The intelligent traffic energy-saving street lamp is structurally characterized by comprising an energy-saving controller, a control circuit and an adaptive light intensity street lamp, wherein the energy-saving controller is connected with an electric power line; the control circuit is connected with the energy-saving controller, and sends or receives analog signals; and the adaptive light intensity street lamp is connected with the control circuit, and receives and / or sends the analog signals. The intelligent traffic energy-saving street lamp is used for building an intelligent traffic lighting system.

Description

technical field [0001] The invention relates to an intelligent traffic lighting system, in particular to an intelligent traffic energy-saving street lamp with adaptive light intensity. Background technique [0002] Existing traffic lighting devices usually use street lamps with fixed time and fixed light intensity; there is a problem of wasting electric energy, such as in summer evening, when the natural light intensity is relatively sufficient, the light is triggered at regular intervals, resulting in energy waste; The problem of ambient light changing the light intensity, such as the street lights at the entrance of the tunnel, no matter whether the driver enters the tunnel or drives out of the tunnel, because the human eye needs to react to the change of light intensity, the driver will have an obvious short-term visual sensitivity decline; lack of emergency power supply, For example, at the crossroads, the lighting cannot be guaranteed when the power failure occurs in th...
