The following specific examples are given by way of illustration only and not by way of limitation, and it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made in the examples without inventive faculty, and yet still be protected by the scope of the claims.
The scheme is realized by the following technical means:
example 1: the embodiment provides a light curtain type traffic signal lamp which is arranged at a bifurcation or a crossroad, can ensure the display effect under the complex weather conditions of sand, dust, rain, snow and the like and accurately guide information for pedestrians and drivers.
Due to the fact that light rays emitted by a conventional traffic signal lamp have limited penetrating capacity under the complex weather conditions of sand, dust, rain, snow and the like, the situation that pedestrians or drivers go to the middle of the intersection and find the indication signals which violate the traffic signal lamp and are actually emitted is easy to occur. The light curtain type traffic signal lamp provided by the scheme ingeniously utilizes the media floating in the air, such as sand dust, water mist and the like which can block and influence the display effect of the display signal lamp under the conventional condition, so that a bright light path is formed and a light curtain is formed by interweaving when laser beams irradiate the media to scatter, and the prompt and guide effect is directly played for pedestrians or drivers at a close distance.
Specifically, the light curtain type traffic signal lamp comprises a first rod piece 1 and a second rod piece 2 which are fixed on two sides of a passing road in a split manner. The first rod member 1 is hollow, a laser generating device 3 as a light source is arranged at the upper part of the formed cavity, and a light curtain generating system 4 for reflecting laser beams emitted by the laser generating device 3 as a single light source back and forth between the first rod member 1 and the second rod member 2 so as to interweave and form a light curtain is arranged between the two rod members. The most important part of the light curtain generating system 4 is a reflection assembly 5, the reflection assembly 5 specifically includes two specular reflection plates 6 respectively mounted on the first rod 1 and the second rod 2, the specular reflection plates 6 on both sides are vertically mounted and attached to the rods, and the specular parts on the two specular reflection plates are symmetrical to each other. At this time, when the laser beam emitted from the laser generator 3 is irradiated onto the specular reflection plate 6 of the second rod 2 at a certain inclination angle, an incident angle is formed between the laser beam and the horizontal plane, and the laser beam is irradiated onto the specular reflection plate 6 of the first rod 1 again at an outgoing angle of the same angle after passing through the specular reflection plate 6 of the second rod 2. By repeating the above process, the laser beam can repeatedly irradiate between the first rod member 1 and the second rod member 2, and simultaneously, media such as sand, dust, mist and the like between the two rod members are illuminated in the process to form a bright light curtain, thereby playing an effective prompting effect on pedestrians and drivers.
Preferably, an angle adjusting mechanism 7 for adjusting the irradiation angle of the laser beam emitted from the laser generating device 3 to the other rod member is provided between the rod member on which the laser generating device 3 is mounted and the laser generator device. Specifically, the laser generator device is movably arranged in the first rod piece 1 and can swing in a certain angle range around a fixed hinge center; the tail end of the laser generator is connected to the rotary adjusting disc through a transmission rod in a same hinged mode, and the transmission rod and the rotary adjusting disc are fixed through a hinged structure; a part of the rotation adjusting plate protrudes from the outer wall surface of the first pin 1. Under this structure, it is rotatory to rotate the adjustment disk through stirring, just can drive laser generating device 3 and swing in certain angle range to change the incident angle and the angle of emergence of laser beam, and then adjust control according to the actual demand condition to the fine and close degree of signal light curtain, the coverage that form.
Further, in order to enhance the light-emitting display effect of the light curtain, a back-lighting component 9 whose surface is also set as a mirror surface is installed at the bottom of the first rod 1, and the mirror-surface-shaped surface of the back-lighting component 9 is approximately perpendicular to the incident direction of the laser beam, so that the laser beam can reversely illuminate the medium between the two rods through reflection and basically in the same path, and the medium is illuminated from two directions and outwardly diverges the laser beam, so that the display effect of the light curtain is better and clearer. In consideration of the need for angle adjustment of the laser generator 3, an angle linkage mechanism 8 for changing the angle of the retroreflecting member 9 in accordance with the swing of the laser generator 3 may be further installed between the retroreflecting member 9 and the angle adjustment mechanism 7. Specifically, the angle linkage mechanism 8 includes another rotating disc capable of rotating around the center, a first transmission rod and a second transmission rod are respectively arranged on two sides of the rotating center on one end face of the rotating disc, two ends of the first transmission rod are respectively and fixedly mounted on the rotating disc and the laser generating device 3 in a hinged mode, and two ends of the second transmission rod are respectively and fixedly mounted on the rotating disc and the illumination component 9 in a hinged mode. At this time, when the irradiation angle of the laser generator 3 is adjusted and changed, the backlighting component 9 located at the lower part is also rotated accordingly, so that the direction of irradiating the laser beam onto the surface of the backlighting component 9 and the surface of the backlighting component 9 are always ensured to be in a mutually perpendicular state.
Furthermore, the light curtain type traffic signal lamp also comprises a warning generation device and a light sensation trigger device which are electrically linked with each other. When the light curtain type traffic signal lamp displays a red light curtain which is forbidden to pass, pedestrians or vehicles cross the forbidden line position and block laser beams, the light sensation trigger device can be started, and the warning sounding device is triggered to give out a warning sound so as to timely remind people of paying attention to the position condition of the people and improve the safety.

The lamp post is also internally provided with a brightness adjusting device for adjusting the brightness of the laser beam emitted by the laser generating device 3 according to the visible degree of the environment, so that the energy-saving and emission-reducing effects of environmental protection are achieved by adjusting the working conditions of the equipment according to different actual environments.
Example 2: in this embodiment, considering that the laser beam in embodiment 1 is reflected back and forth between the two rods at a certain inclination angle, the optical path in the formed light curtain is also in a moving inclined straight line shape, which has a certain influence on the pedestrians or drivers to observe the traffic situation behind the light curtain, and is not favorable for real-time grasping of the actual road surface condition. Thus, in the light curtain type traffic signal lamp of embodiment 1, the specular reflection plate 6 of the second rod 2 of the first rod 1 may be replaced with a plurality of independent reflection units 5 a. Specifically, the independent reflection unit 5a is mounted on the outer wall surface of the rod, an inner concave portion is formed in the reflection unit 5a, a first reflection surface 5a1 and a second reflection surface 5a2 are respectively formed at the upper end and the lower end of the inner concave portion, an included angle of 45 degrees is formed between the first reflection surface 5a1 and the second reflection surface 5a2 and the horizontal plane, and the first reflection surface 5a1 and the second reflection surface 5a2 are in mirror symmetry with each other relative to the horizontal plane at the middle position between the two. In this configuration, the laser beam emitted from the adjustment laser generator 3 is irradiated to the first reflection surface 5a1 in the horizontal direction, and the reflection unit 5a deflects the laser beam downward and then emits the laser beam backward in the horizontal direction. Under the effect of a plurality of reflection units 5a arranged on two rod pieces in a splitting way, a signal light curtain which is composed of light paths extending along the horizontal direction is formed, the conventional observation habit of pedestrians and drivers to external objects is better met, the phenomenon that people are dazzled or dizzy is prevented, and the safety of the equipment during working is improved.
While the utility model has been described with reference to specific embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
