Description

Technical Field

[0001] The utility model relates to the technical field of tunnel lighting, in particular to a tunnel dark field angle lamp. Background Art

[0002] Tunnel lighting can improve the road conditions in the tunnel, improve the visual enjoyment in the tunnel, reduce driver fatigue, and help improve the tunnel's traffic capacity and ensure traffic safety. Specifically, some special visual phenomena must be considered in tunnel lighting, among which the internal lighting has stricter requirements due to the lack of external natural light.

[0003] The prior art, such as publication number CN213299742U, provides a tunnel lighting device, including a fixing mechanism, a lamp holder mechanism and a connecting mechanism. The fixing mechanism includes a mounting rod, a plug-in slot, a positioning slot and a reserved hole. The plug-in slot is arranged on the lower surface of the mounting rod, the positioning slot is symmetrically arranged on the side wall of the plug-in slot, and the reserved hole penetrates the surface of the mounting rod and the inner wall of the plug-in slot. The lamp holder mechanism is plugged into the inner side of the fixing mechanism through the connecting mechanism, and the positioning plate is plugged into the inner side of the positioning slot, and the positioning magnet is used to absorb the mounting rod for positioning. When disassembly is required, the lamp holder mechanism can be removed for inspection by simply pulling it downward; the connection between the lamp holder mechanism and the lamp shade mechanism is sealed by the external thread of the lamp shade mechanism, and the air between the lamp holder mechanism and the lamp shade mechanism can be dried by the drying mechanism, so as to effectively prevent the humid air in the lamp shade body from condensing into water droplets and affecting the lighting.

[0004] However, tunnel lights installed in tunnels are usually installed at intervals, which makes the longitudinal brightness of the tunnel uneven. During driving, there will be a stroboscopic effect of alternating light and dark, which greatly affects the lighting comfort of people during driving. If the tunnel is too long, it is easy to cause visual fatigue to the driver. Moreover, current tunnel lights usually emit light from point sources, and the light surface is dazzling, making it difficult for people to look directly at the lamps, which is very likely to produce uncomfortable glare. In view of this, we propose tunnel dark field angle lights. Utility Model Content

[0005] The utility model aims to provide a tunnel dark field angle lamp, which solves the problem that people cannot look directly at the lamp and easily generate uncomfortable glare.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A tunnel dark field angle lamp comprises a mounting seat, a lighting lamp is arranged on the front of the mounting seat, a glass lampshade of the lighting lamp is arranged in a rectangular shape, a connecting block is connected to the back of the lighting lamp, a clamping block is connected to the front of the mounting seat, the connecting block is hinged to the clamping block through a support shaft, the outer walls at both ends of the support shaft are respectively provided with clamping grooves, the inner walls of the clamping grooves are clamped with elastic telescopic rods, and the elastic telescopic rods are connected to the front of the mounting seat, and the rectangular glass lampshade is adopted so that the light emitted by the lighting lamp is a rectangular light spot, and when multiple groups of lamps are used at the same time, they can be connected in sequence according to the rectangular light spots. By evenly arranging the lamps on the walls on both sides of the tunnel in a manner, the utilization rate of the light from the lamps can be improved, and a situation where a large difference in brightness occurs, with one lamp being bright and the other being dark, can be avoided when passing between two groups of lamps, so as to reduce the situation where the driver's eyes are uncomfortable due to the large difference in brightness in the tunnel. In addition, by hingedly connecting the connecting block and the card block through the support shaft, the left and right angles of the lamp can be adjusted, so that the lamp can be easily rotated to tilt in the direction of the car's travel, so as to avoid direct light from the light source in the direction the driver is facing when the car enters, which is very likely to cause uncomfortable glare.

[0008] Preferably, the elastic telescopic rod is composed of a support rod, a slide groove, a sliding rod, and a spring. The slide groove is opened on the inner wall of the support rod, the sliding rod is slidably connected to the inner wall of the slide groove, and a spring is connected between the slide groove and the sliding rod.

[0009] Preferably, the slots are evenly arranged in a ring shape, the position where the slide bar contacts the slots is set at an acute angle, and the acute angle is set in a circular arc to facilitate detachment from the slots.

[0010] Preferably, mounting holes for inserting bolts are provided at the four corners of the mounting seat to facilitate the fixed installation of the lamp, and a ventilation mechanism is provided on the right side of the front of the lighting lamp.

[0011] Preferably, the ventilation mechanism includes a baffle, which is connected to the right side of the front of the lighting lamp. A guide groove is provided on the inner wall of the baffle. The baffle can block the light directly irradiated in the direction of the driver by the lighting lamp, and the guide groove guides the airflow generated by vehicles passing through the tunnel.

[0012] Preferably, the guide groove faces the glass lampshade on the front side of the lighting lamp, and the openings at both ends of the guide groove are larger on the right and smaller on the left, so that the air can be blown toward the glass lampshade on the front side of the lighting lamp. Since the openings at both ends of the guide groove are larger on the right and smaller on the left, the blown air is pressurized, and the wind speed is faster when passing through the glass lampshade, which can play a role in cooling the glass lampshade. At the same time, the faster wind speed makes it difficult for the dust raised by the passing of vehicles in the tunnel to adhere to the glass lampshade, so as to avoid excessive dust adhering to the glass lampshade and affecting the penetration of light.

[0013] Preferably, an air collecting hood is connected to the outside of the guide groove on the right side of the baffle, and a reflective sheet is connected to the right side of the baffle, and the reflective sheet is arranged at an angle. By setting the air collecting hood to guide the airflow, the reflective sheet can reflect the emitted light, thereby avoiding the loss of part of the light due to blocking by the baffle.

The utility model can block the light directly irradiated in the direction of the driver by the baffle plate, and the guide groove guides the airflow generated by the vehicles passing through the tunnel, so that it can be blown to the glass lampshade in front of the lighting lamp. Moreover, since the openings at both ends of the guide groove are larger on the right and smaller on the left, the blown air is pressurized, and the wind speed is faster when passing through the glass lampshade, which can play a role in cooling the glass lampshade. At the same time, the faster wind speed makes it difficult for the dust raised by the passing of vehicles in the tunnel to adhere to the glass lampshade, so as to avoid excessive dust adhering to the glass lampshade and affecting the light penetration.

By adopting a rectangular glass lampshade, the light emitted by the lighting lamp 2 is rectangular. When multiple groups of lamps are used at the same time, the light spots can be evenly arranged on the walls of both sides of the tunnel in a manner of connecting in sequence with rectangular light spots, which can improve the utilization rate of the light of the lamps and avoid the situation where one is bright and the other is dark due to a large difference in brightness when passing through the position between the two groups of lamps, so as to reduce the situation where the driver's eyes are uncomfortable due to the large difference in brightness in the tunnel, and the connecting block 21 and the clamping block 22 are hinged by the support shaft 23, so that the left and right angles of the lighting lamp 2 can be adjusted to facilitate the rotation of the lighting lamp 2 to the tilted position. In the direction of the car's travel, in order to avoid the direction in which the driver is facing when the car enters, there is direct light from the light source, which is very likely to cause uncomfortable glare. The elastic telescopic rod 24 is composed of a support rod 241, a slide groove 242, a slide rod 243, and a spring 244. The slide groove 242 is opened on the inner wall of the support rod 241, and the slide rod 243 is slidably connected to the inner wall of the slide groove 242.

When multiple groups of lamps are used at the same time, they can be evenly arranged on the walls on both sides of the tunnel in a manner of connecting in sequence with rectangular light spots, so as to improve the utilization rate of the light of the lamps and avoid the situation where one is bright and the other is dark due to a large difference in brightness when passing through the position between the two groups of lamps, so as to reduce the situation where the driver suffers from eye discomfort due to the large difference in brightness in the tunnel, and the connecting block 21 and the clamping block 22 are hinged by the support shaft 23, so as to adjust the left and right angles of the illuminating lamp 2, so as to facilitate the illuminating lamp 2 to be rotated to be inclined in the driving direction of the car, so as to avoid the light from the light source being directly irradiated in the direction facing the driver when the car enters, and the sliding rod 243 is slidably connected in the sliding groove 242 and supported by the tension of the spring 244, so that when there is no external force, the elastic telescopic rod 24 clamps the clamping groove 25 to the illuminating lamp 2 has a positioning effect. When the angle of the lighting lamp 2 needs to be changed, the lighting lamp 2 is pushed by manpower to squeeze the spring 244 in the elastic telescopic rod 24 to make the slide bar 243 contract, and the contact and the limit relationship of the card slot 25 are convenient for rotation adjustment. The baffle 31 can be set to block the light of the lighting lamp 2 directly irradiating the driver. The reflector 34 can reflect the emitted light to avoid the loss of part of the light due to the baffle 31. The airflow generated by the vehicles passing through the tunnel is guided by the wind collecting cover 33 and the guide groove 32, which can be blown to the glass lampshade on the front of the lighting lamp 2. Since the openings at both ends of the guide groove 32 are set larger on the right and smaller on the left, the blown air is pressurized, and the wind speed is faster when passing through the glass lampshade, which can play a role in cooling the glass lampshade. At the same time, the faster wind speed makes it difficult for the dust raised by the vehicles passing through the tunnel to adhere to the glass lampshade, so as to avoid too much dust adhering to the glass lampshade and affecting the light penetration.
