Problems solved by technology

In dense fog, due to the extremely low visibility, cars need to be at a relatively short distance to see traffic lights clearly. As a result, fast-moving vehicles in the rear are very likely to rear-end vehicles waiting for a red light at the intersection in front, causing traffic accidents. ACCIDENT
It can be seen that the current traffic lights still need to be improved.

Embodiment 1

[0019] The self-adaptive traffic light involved in the present invention includes three lamp holders of red, yellow and green. exist figure 1 , figure 2 In the shown embodiment one, each lamp cap includes a base shell 1, and a light source 2 disposed in the base shell 1, the light source 2 is driven by a driving board 21 to generate a horizontal light beam directed forward; the base shell 1 The front part is provided with a light-emitting panel 3 with uniformly distributed light holes 30 on the surface. The light-emitting panel 3 is composed of an optical atomized plate, such as an atomized acrylic plate; when the horizontal beam is irradiated on the light-emitting panel 3, the light-emitting panel 3 is even light; the base shell 1 is also provided with a control mechanism that can control the longitudinal displacement of the light-emitting panel 3; the traffic light also includes a fog sensor mechanism; the fog sensor mechanism senses the dense fog During weather condition...

Embodiment 2

[0025] for image 3 The second embodiment shown is different from the first embodiment in that: the mist sensing mechanism is an infrared transceiver 6 disposed on the base shell 1 and facing the ground; The infrared transmitting head sends infrared signals to the ground at fixed time intervals; and the infrared receiving head in the infrared transceiver 6 receives the infrared signal reflected back from the ground, when the reflected infrared signal strength received by the infrared receiving head When it is lower than the set value, it is judged as dense fog weather. The infrared transceiver 6 in the second embodiment can be purchased directly. Compared with the traditional fog sensor, the infrared transceiver 6 sends infrared signals to the ground, and the intensity of the reflected infrared signal is almost only affected by the concentration of fog in the air (water vapor can absorb a large amount of infrared radiation), while other conditions affect its The influence is...

Embodiment 3

[0027] for Figure 4 The third embodiment shown is different from the first embodiment in that the control mechanism includes a constraining spring 7 arranged on the upper side of the light-emitting panel 3 and a hole-like light-transmitting spring attached to the back of the light-emitting panel 3 . layer 31; the light exit hole 30 runs through the light-emitting panel 3 and the porous light-transmitting layer 31; the porous-shaped light-transmitting layer 31 can be made of a transparent resin material through a foaming process; A pinhole layer densely covered with pores is pressed on the light-emitting panel 3 to form the porous light-transmitting layer; a layer of unidirectional or criss-cross gully layers can also be made on the back of the light-emitting panel 3 through a wire drawing process, The porous light-transmitting layer is formed.

[0028]When the weight of accumulated water on the surface of the porous light-transmitting layer 31 does not exceed the design leve...

Abstract

The invention provides a self-adaptive traffic light comprising red, yellow and green lamp holders; each lamp holder comprises a base shell and light sources, horizontal light beams that are emitted forward are generated via the light sources, an illuminating panel formed by an optical atomization plate is placed before the base shell, a surface of the illuminating panel is provided with light through holes that are uniformly distributed, a control mechanism capable controlling the illuminating panel to move in a lengthways manner is arranged in the base shell, and the traffic light also comprises a fog sensing mechanism; when thick fog weather is sensed via the fog sensing mechanism, the control mechanism controls the illuminating panel to move lengthways to a second work station, and all horizontal light beams are emitted out right through all the light through holes on the illuminating panel; in non-thick-fog weather, the illuminating panel moves lengthways to a first work station, all the horizontal light beams illuminate the illuminating panel which is then enabled to send out uniform light. Via the self-adaptive traffic light, visibility of light can be remarkably increased in the thick fog weather, traffic signals can be seen clearly by car drivers far away, and therefore traffic safety can be improved.

Description

technical field [0001] The invention relates to the field of traffic facilities, in particular, to a traffic light. Background technique [0002] Traffic light is a basic traffic facility, which can greatly improve the traffic order at traffic intersections. In dense fog, due to the extremely low visibility, cars need to be at a relatively short distance to see traffic lights clearly. As a result, fast-moving vehicles in the rear are very likely to rear-end vehicles waiting for a red light at the intersection in front, causing traffic accidents. ACCIDENT. It can be seen that the current traffic lights still need to be improved. Contents of the invention [0003] In view of the above problems, the object of the present invention is to provide an adaptive traffic light, which can greatly improve the visibility of the light in dense fog weather, so as to ensure that vehicles far away can see the traffic signals clearly, so as to improve traffic lights. Safety. [0004] Th...
