Problems solved by technology

For this situation, in some current intelligent design schemes of traffic lights, the optical sensor is used to analyze the intensity of the background light, and then calculate the reasonable brightness of the signal light, and then adjust the input current of the signal light to adaptively adjust the brightness of the signal light , although this kind of intelligent solution can solve the problem of background sunlight, but this set of intelligent system involves power regulation system, the cost is relatively high, therefore, it has not been popularized

Embodiment 1

[0015] exist figure 1 In the first embodiment shown, the solar traffic light includes a base shell 1, and a color-changing signal light is arranged in front of the base shell 1, and the signal light includes a circular light-emitting panel 2 composed of an optical diffusion plate and a Side, and a controllable color-changing lamp 20 that projects from the side to the interior of the light-emitting panel; the rear of the light-emitting panel 2 of the signal light includes three color filter units, and each of the color filter units includes a cavity slideway 3, the The cavity slide 3 can be in the shape of an upright flat box, and a light hole 30 facing the light emitting panel 2 is opened in the middle thereof, and the light hole 30 is a round hole having an area equivalent to the light emitting panel 2 .

[0016] One side of the cavity slideway 3 is provided with an electromagnet 4, and the other side is provided with a colored transparent film roll 60, and the colored transp...

Embodiment 2

[0020] figure 2 Shown is Embodiment 2 of this solar traffic light, which is different from Embodiment 1 in that: a reflection unit is also provided behind the rearmost color filter unit, and the structure of the reflection unit is the same as that of the color filter unit. The structure is the same, and only the specular reflection film 9 is used to replace the colored transparent film; the rear surface of the base shell 1 is also provided with a photosensitive sensor 91; the electromagnet of the reflection unit and the photosensitive sensor are simultaneously coupled to the A controller 8; when the brightness of light sensed by the photosensitive sensor 91 is lower than a set value, the controller 8 turns on the electromagnet of the reflection unit; otherwise, turns off the electromagnet. Its advantage is that: when the background light is insufficient, the light emitted by the light-emitting panel 2 to the rear can be reflected back to the front through the mirror reflectio...

Embodiment 3

[0022] For Embodiment 3, the difference from Embodiment 1 is that an adaptive reflector is provided on the area where the rear surface of the base shell 1 faces the light-emitting panel 2; Set an adaptive reflector inside.

[0023] The adaptive reflector such as image 3 As shown, it includes a thin cavity 100 sandwiched by double-layer transparent plates, and an elastic bag 101 laterally connected to the thin cavity; mercury is injected into the elastic bag 101 and the thin cavity 100; The thin cavity 100 is also provided with a transparent elastic inner cavity, which is filled with a low-boiling liquid with a boiling point between 25°C and 35°C; when the low-boiling liquid is in a liquid state, the thin cavity 100 The mercury inside surrounds the elastic inner cavity; when the low boiling point liquid is in gaseous state, the elastic inner cavity expands and fills the entire thin cavity 100, driving all the mercury in the thin cavity into the elastic bag 101.

Abstract

The invention provides a solar traffic lamp, and the traffic lamp comprises a base housing, wherein the front of the base housing is provided with a signal lamp and the base housing comprises a light-emitting panel and a controllable color-changing lamp. Three color filtering units are disposed behind the light-emitting panel, and respectively comprise a cavity chute, wherein the central part of each cavity chute is provided with a light hole. One side of each cavity chute is provided with an electromagnet, and the other side of each cavity chute is provided with a colored transparent film roll, wherein the colored transparent film roll comprises a spring shaft and a colored transparent film wound around the spring shaft. One end of each colored transparent film is connected with an iron sliding block in the corresponding cavity chute. Three color filtering units respectively comprises one of colored transparent rolls (red, yellow and green). The controllable color-changing lamp comprises three lamp wicks: red, yellow and green. All lamp wicks and all electromagnets are controlled by a controller. When the controller turns on one lamp wick, one electromagnet corresponding to the color of the lamp wick is connected at the same time. The rear surface of the base housing is transparent. The traffic lamp can enable the brightness of the signal lamp to be improved at lower cost under the irradiation of background sunlight.

Description

[0001] This application is a divisional application of the patent application with the application number 201410755641.8 and the name is solar energy-enhanced traffic lights. technical field [0002] The invention relates to the field of road traffic facilities, in particular to a traffic light. Background technique [0003] Traffic lights are the infrastructure to ensure road traffic safety, and in sunny conditions, because the traffic lights are above the driver's field of vision, if they happen to face the sun, the normal brightness of the signal lights will not allow the driver to see the signal clearly due to the extremely strong background light. Therefore, it is necessary to enhance the brightness of the signal light at this time. For this situation, in some current intelligent design schemes of traffic lights, the optical sensor is used to analyze the intensity of the background light, and then calculate the reasonable brightness of the signal light, and then adjust ...
