Description

Technical Field

[0001] The invention relates to the technical field of traffic signal lamps, and in particular to a laser source traffic signal indicating device. Background Art

[0002] Traffic signals are lights that direct traffic movements and are generally composed of red, green and yellow lights. The red light means no passage, the green light means passage is allowed, and the yellow light means warning.

[0003] Traffic lights are divided into: motor vehicle lights, non-motor vehicle lights, pedestrian crossing lights, direction indicator lights (arrow lights), lane lights, flashing warning lights, and road and railway level crossing lights.

[0004] LED (light emitting diode) is a newly developed new type of traffic light source, which has gradually replaced incandescent lamps and low-voltage halogen tungsten lamps to make road traffic lights.

[0005] However, LED lights can only form limited traffic signals. Only the green signal light has less scattering in dense fog, while the red and yellow signal lights have a lot of scattering in dense fog. In addition, there is a lack of more obvious indications on non-straight roads and other situations. Users can only see the indicator lights in the opposite direction. Especially when visibility is low, it is more difficult to determine accurate road sign information.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices consistent with some aspects of the present invention as detailed in the appended claims.

[0028] like Figure 1 and Figure 2As shown, a laser source traffic signal indication device provided by an embodiment of the present invention comprises a mounting bracket 1, on which a green laser source signal light, a red laser source signal light and a yellow laser source signal light are arranged at intervals, the wavelength of the green laser source signal light is 620-750nm, the wavelength of the red laser source signal light is 450nm-495nm, the wavelength of the yellow laser source signal light is 400nm-750nm, and the laser sources of the green laser source signal light, the red laser source signal light and the yellow laser source signal light all adopt level 3 and below laser sources to avoid causing harm to the human body; the green laser source signal light comprises a green laser emitting device and a first control device, the red laser source signal light comprises a red laser emitting device and a second control device, and the yellow laser source signal light comprises a yellow laser emitting device and a third control device; the first control device is used to control the green laser emitting device to emit a green laser beam 101, the second control device is used to control the red laser emitting device to emit a red laser beam 102, and the third control device is used to control the yellow laser emitting device to emit a yellow laser beam 103.

[0029] The laser source traffic signal indicating device provided by the present invention is configured to include a mounting bracket 1, and a green laser source signal light, a red laser source signal light and a yellow laser source signal light are arranged on the mounting bracket 1 at intervals, and the green laser source signal light includes a green laser emitting device and a first control device, the red laser source signal light includes a red laser emitting device and a second control device, and the yellow laser source signal light includes a yellow laser emitting device and a third control device, and the first control device controls the green laser emitting device to emit a green laser beam 101, the second control device controls the red laser emitting device to emit a red laser beam 102, and the third control device controls the yellow laser emitting device to emit a yellow laser beam 103, so as to respectively form a permitted passage indicating intersection and signal, a prohibited passage indicating intersection and signal, and a warning indicating intersection and signal, so that the indicating device in the present invention can utilize the laser with higher brightness and better penetration performance, so that not only the indicating effect is more obvious when the visibility is low, but also the laser light source is used as a traffic signal indicator light, which is easier to be collected to form an intelligent traffic network.

[0030] It should be noted that the use of laser light sources as traffic signal indicator lights in this embodiment is easier to collect and form an intelligent traffic network. This can be understood as follows: Since the laser beam in the present invention is emitted by a laser emitting device controlled by a control device, in actual implementation, it is only necessary to control the control device to control the time, intensity, emission duration and other information of the laser beam emitted by the laser emitting device. Therefore, the use of laser light sources as traffic signal indicator lights in this embodiment is easier to collect and form an intelligent traffic network.

[0033] Exemplarily, the intensity of natural light can be divided according to time periods. For example, the night time period from 20:00 to 7:00 in a certain place can be considered as weak natural light, and the day time period from 7:00 to 20:00 can be considered as strong natural light.

[0034] In one implementation, Figure 2 As shown, the mounting bracket 1 is arranged on one side of the target road surface; the green laser emitting device, the red laser emitting device and the yellow laser emitting device are all vertically mounted on the mounting bracket 1, so that the green laser beam 101 emitted by the green laser emitting device, the red laser beam 102 emitted by the red laser emitting device, and the yellow laser beam 103 emitted by the yellow laser emitting device can all be transmitted parallel to the target road surface, so as to form a beam wall when the ambient light on the target road surface is weak, and form corresponding traffic signals on the reflecting surface and the lamp holder when the ambient light is strong.

[0035] In this embodiment, the mounting bracket 1 is arranged on one side of the target road surface, and the green laser emitting device, the red laser emitting device and the yellow laser emitting device are all vertically mounted on the mounting bracket 1, so that the green laser beam 101 emitted by the green laser emitting device, the red laser beam 102 emitted by the red laser emitting device, and the yellow laser beam 103 emitted by the yellow laser emitting device can all be transmitted parallel to the target road surface, so as to form a beam wall when the ambient light on the target road surface is weak, and form a corresponding traffic signal on the reflective surface and the lamp holder when the ambient light is strong, and the extension direction of the beam curtain is exactly perpendicular to the extension direction of the road surface, so that pedestrians and drivers can clearly identify the traffic signal.

[0038] Preferably, the green laser receiving device and the green laser emitting device are on the same straight line, the red laser receiving device and the red laser emitting device are on the same straight line, and the yellow laser receiving device and the yellow laser emitting device are on the same straight line.

[0039] In this embodiment, by arranging the green laser receiving device and the green laser emitting device on the same straight line, the red laser receiving device and the red laser emitting device on the same straight line, and the yellow laser receiving device and the yellow laser emitting device on the same straight line, the laser receiving device can collect all the laser beams emitted by the laser emitting device, thereby completely avoiding the laser beam emitted by the laser emitting device from causing light pollution to the opposite lane.

[0040] Preferably, the signal indication device also includes a power supply device, which supplies power to the green laser emitting device, the first control device, the green laser receiving device, the red laser emitting device, the second control device, the red laser receiving device, the yellow laser emitting device, the third control device and the yellow laser receiving device.
