However, under the condition of facing the sun, a driver usually clearly sees the current color of the traffic light to the front and the upper side, and the red light running phenomenon is easy to happen, so that the traffic safety hidden trouble is caused.
Disclosure of Invention
In view of the above problems, an object of the present invention is to provide an anti-glare traffic light that can improve traffic safety by allowing a driver to easily see a current light color when facing the sun.
The technical scheme adopted by the invention for solving the technical problems is as follows: the anti-glare traffic light comprises three lamp heads of red, yellow and green; each lamp holder comprises a base shell, and a cylindrical cavity extending forwards and backwards is formed in the base shell; a monochromatic light source coaxial with the cavity is arranged in the cylindrical cavity, an electro-mirror glass obliquely arranged at an angle of 45 degrees with the horizontal plane is arranged in front of the monochromatic light source, and when the electro-mirror glass is in a mirror surface state, light emitted by the monochromatic light source can be reflected downwards; a transparent plate is arranged below the electro-mirror glass, and an optical diffusion plate is arranged in front of the electro-mirror glass; a photovoltaic panel is arranged behind the monochromatic light source, and external sunlight can irradiate into the cylindrical cavity from the back of the base shell and irradiate on the photovoltaic panel; the photovoltaic panel passes through a switch module and then is output to the electro-mirror glass, and the switch module only enables the photovoltaic panel to be connected with the electro-mirror glass when the output voltage of the photovoltaic panel exceeds a set threshold value; the electro-mirror glass is in a mirror state when being electrified and is in a transparent state when being powered off.
Preferably, the monochromatic light source is a directional light source, and horizontal forward illumination is generated.
Preferably, the electro-specular glass comprises double glass layers, a sealed thin layer is formed between the double glass layers, and the thin layer is sealed with silver ion solution; the surfaces of the double-layer glass are respectively plated with a layer of transparent conductive film, and the transparent conductive films on the double-layer glass are respectively connected with one electrode of the same direct current power supply; when the electro-mirror glass is electrified, silver ions in the thin layer are separated out under the action of a transverse electric field and are attached to the surface of the glass connected with the negative electrode of the direct-current power supply to form a mirror; and when the power of the electro-mirror glass is cut off, the silver ions are dissolved in the solution again, and the electro-mirror glass returns to the transparent state.
Preferably, the photovoltaic panel is obliquely arranged in the cylindrical cavity, the lighting surface of the photovoltaic panel is obliquely upward, and the intersection angle between the photovoltaic panel and the vertical plane is 15-30 degrees; when the inclination angle between the sun and the ground is 15-30 degrees, (at the moment, an automobile driver facing the sun is dazzled), the sunlight illumination is approximately vertical to the photovoltaic panel, and the output voltage of the photovoltaic panel is approximately maximum.
Preferably, the monochromatic light source is an annular light source and generates horizontal forward illumination; the photovoltaic panel is an annular panel, and can enable a part of sunlight to pass through the photovoltaic panel and a monochromatic light source and then irradiate the electro-mirror glass; the transparent plate is a light filter plate and only can pass the light with the color consistent with that of the monochromatic light source; therefore, sunlight which irradiates on the electric mirror glass and is downwards reflected to the ground obviously enhances traffic signal light spots which are reflected to the ground by the electric mirror glass by the monochromatic light source, so that the observability is further improved.
The invention has the beneficial effects that: under the condition that the sunlight illumination behind the lamp cap is low, the voltage output of the photovoltaic panel is weak, the electro-mirror glass is in a power-off state, namely is transparent, and the illumination generated by the monochromatic light source is directly projected on the optical diffusion plate, so that a common traffic signal is formed; and under the condition that the sunlight behind the lamp holder is strong in illumination, the voltage output of the photovoltaic panel is greatly increased, so that the electro-mirror glass is in a power-on state, the illumination of the monochromatic light source is reflected to the ground by the electro-mirror glass, and a traffic signal light spot is formed on the ground.

Detailed Description
The invention is further illustrated with reference to the following figures and examples:
the first embodiment is as follows:
the invention relates to an anti-glare traffic light which comprises three lamp heads of red, yellow and green; the embodiment of each lamp head is as shown in fig. 1 and fig. 2: the device comprises a base shell 1, wherein a cylindrical cavity 10 extending forwards and backwards is formed in the base shell 1; a monochromatic light source 2 coaxial with the cavity is arranged in the cylindrical cavity 10, an electro-mirror glass 3 obliquely arranged at an angle of 45 degrees with the horizontal plane is arranged in front of the monochromatic light source 2, and when the electro-mirror glass 3 is in a mirror state, light emitted by the monochromatic light source 2 can be reflected downwards; a transparent plate 4 is arranged below the electro-mirror glass 3, and an optical diffusion plate 5 is arranged in front of the electro-mirror glass 3; a photovoltaic panel 6 is arranged behind the monochromatic light source 2, and external sunlight can irradiate into the cylindrical cavity 10 from the back of the base shell 1 and irradiate onto the photovoltaic panel 6; the photovoltaic panel passes through a switch module (not shown) and then is output to the electro-mirror glass 3, and the switch module only enables the photovoltaic panel 6 to be connected with the electro-mirror glass 3 when the output voltage of the photovoltaic panel 6 exceeds a set threshold value; the electro-mirror glass 3 is in a mirror state when being electrified and is in a transparent state when being powered off; in particular, the switching module may be constituted by a zener diode, conducting only when the input voltage reaches a threshold value; of course, there are other kinds of switch modules with voltage threshold, which are conventional functional modules in the electronic field and need not be described herein.
In the anti-glare traffic light, the monochromatic light source 2 is a directional light source, and horizontal forward illumination is generated. The electro-mirror glass 3 comprises double glass layers, a sealed thin layer is formed between the double glass layers, and silver ion solution is sealed in the thin layer; the surfaces of the double-layer glass are respectively plated with a layer of transparent conducting film, such as an indium tin oxide film; the transparent conductive films on the double-layer glass are respectively connected with one electrode of the same direct current power supply (not shown); when the electro-mirror glass 3 is electrified, silver ions in the thin layer are separated out under the action of a transverse electric field and are attached to the surface of the glass connected with the negative electrode of the direct-current power supply to form a mirror surface; and when the power of the electro-mirror glass 3 is cut off, the silver ions are dissolved in the solution again, and the electro-mirror glass 3 returns to the transparent state.
Under the condition that the sunlight illumination behind the lamp cap is low, the voltage output of the photovoltaic panel 6 is weak, the electro-specular glass 3 is in a power-off state, namely is transparent, and the illumination generated by the monochromatic light source 2 is directly projected onto the optical diffusion plate 5 as shown in fig. 1, so that a common traffic signal is formed; and under the condition that the sunlight behind the lamp holder is strong in illumination, the voltage output of the photovoltaic panel 6 is greatly increased, so that the electro-mirror glass 3 is in a power-on state, the illumination of the monochromatic light source 2 is reflected to the ground by the electro-mirror glass 3, as shown in figure 2, a traffic signal light spot is formed on the ground, and at the moment, a driver can clearly observe the traffic signal state due to the fact that the visual angle is obviously reduced, and the traffic safety is improved.
Example two:
for the second embodiment shown in fig. 3, which is different from the first embodiment, the photovoltaic panel 3 is obliquely arranged in the cylindrical cavity 10, the lighting surface of the photovoltaic panel 3 is obliquely upward, and the intersection angle between the photovoltaic panel 3 and the vertical plane is 15-30 °; when the inclination angle between the sun and the ground is 15-30 degrees, the automobile driver facing the sun is dazzled, at the moment, the sunlight illumination is approximately vertical to the photovoltaic panel 3, and the output voltage of the photovoltaic panel 3 is approximately maximum; therefore, the threshold value of the on-voltage of the switch module can be designed to be a higher level, so that the electro-mirror glass 3 is in a mirror state only under the conditions that the inclination angle between the sun illumination and the ground is 15-30 degrees and the illumination intensity is higher; while avoiding traffic lights from often being in an unusual indicating state.
Example three:
for the third embodiment shown in fig. 4, it is different from the first embodiment in that the monochromatic light source 2 is a ring-shaped light source, and generates horizontal forward illumination; the photovoltaic panel 6 is an annular panel, and a part of sunlight can pass through the photovoltaic panel 6 and the monochromatic light source 2 and then irradiate the electro-mirror glass 3; the transparent plate 4 is a light filter plate and only can pass the light with the color consistent with that of the monochromatic light source 2; therefore, sunlight which irradiates on the electro-mirror glass 3 and is reflected downwards to the ground obviously enhances traffic signal light spots which are reflected to the ground by the monochromatic light source 2 through the electro-mirror glass 3, so that the observability is further improved.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, but rather as the subject matter of the invention is intended to cover all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.
