The utility model provides a kind of tunnel, the adaptive street lamp in engineering bridge opening, including lamp bracket and installed in the lamp bracket
On some light fixtures, the light fixture connects potentiometer respectively by circuit, the potentiometer by connection isolating transformer,
The isolating transformer is connected with power supply, and the power output end is connected with some light intensity detectors, and the light intensity detector connects
Analog-digital converter is connect, the analog-digital converter passes through connection signal processing unit, the signal processing unit
Control signal connection institute is passed through by connection digital analog converter, the output end of the digital analog converter
State light fixture.
As a kind of optimal technical scheme of the present utility model, the output end connection relay of the digital analog converter
Device, and the light fixture is connected by the relay.
As a kind of optimal technical scheme of the present utility model, some light fixtures pass through the independent electricity in parallel of circuit
Position device.
As a kind of optimal technical scheme of the present utility model, some light intensity detectors are evenly distributed on tunnel, work
In journey bridge opening, and spacing between any two is no more than 50 meters.
As a kind of optimal technical scheme of the present utility model, the relay includes error amplifier, pulsewidth modulation electricity
Road, power tube, lock-in tube, energy storage inductor, filter capacitor, sampling resistor, comparator, diode and NPN pipes.
As a kind of optimal technical scheme of the present utility model, the light fixture is evenly distributed on the lamp bracket.
The beneficial effect that the utility model is reached is：The utility model can be according to the intensity of illumination outside tunnel, automatically
The street lamp brightness of the lamp assembly in tunnel is adjusted, makes the brightness of each illuminating lamp gradually strengthen from tunnel face to tunnel internal,
The visual adaptation of vehicle driver's eyes is set to be in the process of gradual change so that driver can see the road of vehicle front clearly at any time
Condition, reduce the traffic accident of the driver caused by illumination variation temporary " blindness ".

Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
Embodiment：As shown in Figure 1-2, the utility model provides a kind of tunnel, the adaptive street lamp in engineering bridge opening, including lamp
Frame 2 and some light fixtures 1 on lamp bracket 2, light fixture 1 connect potentiometer 4 respectively by circuit 3, and potentiometer 4 is connected by circuit
Isolating transformer 5 is connect, isolating transformer 5 is connected with power supply 6, and the output end of power supply 6 is connected with some light intensity detectors 11, and light intensity is visited
Survey device 11 and connect analog-digital converter 10, analog-digital converter 10 passes through connection signal processing unit 9, signal transacting
The control signal of unit 9 is connected by connection digital analog converter 8, the output end of digital analog converter 8 by circuit
Connect light fixture 1.
The output end connection relay 7 of digital analog converter 8, and light fixture 1 is connected by relay 7.Some light fixtures 1 are equal
Pass through the independent potentiometer 4 in parallel of circuit 3.Some light intensity detectors 11 are evenly distributed on tunnel, in engineering bridge opening, and between any two
Spacing be no more than 50 meters.Relay 7 includes error amplifier, pulse-width modulation circuit, power tube, lock-in tube, energy storage inductor, filter
Ripple electric capacity, sampling resistor, comparator, diode and NPN pipes.Light fixture 1 is evenly distributed on lamp bracket 2.
Specifically, street lamp is evenly distributed on tunnel, in engineering bridge opening by the utility model, and by each light fixture and switch electricity
Position device is attached, simultaneously because light intensity detector is mounted with tunnel, for perceiving the light intensity in tunnel, and in the process,
