[0023] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0024] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" may be used interchangeably.
[0025] This utility model embodiment provides a lighting device, such as... Figures 1-3 As shown, the lighting equipment includes a lamp body 1 and a movable bracket 3. The lamp body is equipped with a transparent cover 14 and an adjustable angle connector. The transparent cover 14 is square. The adjustable angle connector is connected to the movable bracket through an angle adjustment structure. The angle adjustment structure is used to adjust the deflection angle of the lighting equipment to adjust the light direction of the lighting equipment.
[0026] This invention relates to a lighting device that uses an angle adjustment structure to adjust the deflection angle of the lighting equipment, thereby adjusting the direction of the light and reducing / preventing glare, resulting in a glare-free lamp. This allows the lighting equipment to be positioned below the driver's eye level for concentrated road illumination. This lighting arrangement changes the traditional phenomenon of numerous lampposts, saving energy, facilitating future maintenance, and reducing construction costs. Furthermore, the low-position lighting equipment integrated with the guardrail creates a linear arrangement of lamps along the roadside, providing visual guidance for drivers while minimizing light interference with surrounding buildings and underpasses, thus protecting the integrity and harmony of the bridge's overall landscape.
[0027] In some embodiments, the lighting device provided by this utility model constitutes a low-profile, front-light-controlled, glare-free LED lighting fixture for roads. It includes a main body 1, which has a bottom and side surfaces. A lighting component is installed inside the main body. A tempered glass cover 14 is installed on the side of the main body away from the movable support. An adjustable angle connector 2 is mounted on the back of the main body via fixing screws. The adjustable angle connector 2 is bolted to the movable support 3, which is then bolted to a highway guardrail / concrete guardrail 5 via bolts 4. The number of bolts is not limited; it can be one or more. The adjustable angle connector 2 and the movable support 3 are used to adjust the deflection angle of the lighting device, thereby adjusting the light direction and reducing / preventing glare.
[0028] In practical applications, the lighting equipment provided by this invention is installed on highway steel or concrete guardrails, integrated with them, and positioned below the driver's eye level to centrally illuminate the road surface. This low-position, glare-free lighting arrangement changes the traditional phenomenon of numerous lighting poles, saving energy, facilitating later maintenance, and reducing construction costs. Furthermore, the low-position lighting combined with the guardrail creates a linear, sequential arrangement of lights along the roadside, providing visual guidance for drivers while minimizing light interference with surrounding buildings and underpasses, thus protecting the integrity and harmony of the overall bridge landscape.
[0029] In some embodiments, the adjustable angle connector 2 and the movable bracket 3 are connected by an angle adjustment structure. After the tilt angle of the lighting equipment is adjusted, the relative positions of the adjustable angle connector 2 and the movable bracket 3 are fixed. The angle adjustment structure includes a positioning hole 21 and an elongated arc hole 22 with adjustable angle provided on the adjustable angle connector 2, as well as positioning bolts 23 and adjusting bolts 24 for fixing the adjustable angle connector 2 and the movable bracket 3.
[0030] The movable bracket 3 includes a base plate and two side plates perpendicular to the base plate. The base plate has one or four through holes for connecting and fixing the entire lighting equipment to the highway steel guardrail post or concrete guardrail 5 by bolts, etc. The side plates have two round holes on the upper part of their side surfaces. The upper hole is a fixing hole and the lower hole is an angle adjustment hole.
[0031] Optionally, the adjustable angle connector 2 can be made of 304 stainless steel. The outer surfaces of both the lamp body 1 and the fixed movable bracket 3 are coated with an anti-corrosion coating. Preferably, an anti-UV powder coating is sprayed onto the outside of the anti-corrosion coating. This anti-UV powder coating significantly improves the product's anti-aging properties and further extends the lifespan of the lighting fixture.
[0032] The adjustable angle connector 2 is set between the two side plates. The positioning hole 21 and the adjustable angle elongated arc hole 22 correspond to the positions of the fixing hole and the adjustment angle hole, respectively. The movable bracket 3 is connected to the adjustable angle connector 2 by the positioning bolt 23 and the adjustment bolt 24. After the angle is adjusted, the two bolts are tightened to fix it.
[0033] The lighting equipment provided by this utility model can adjust the illumination tilt angle of the lighting fixtures through the adjustable angle connector 2 and the movable bracket 3 according to specific road lighting needs, thereby improving the universality and flexibility of the lighting equipment and meeting the needs of road lighting and anti-glare.
[0034] In some implementations, optionally, such as Figure 2 As shown, the width of the elongated arc-shaped hole 22 matches the diameter of the adjusting bolt 24. Both ends of the elongated arc-shaped hole 22 are semi-circular, with the centers of these semi-circles located on the centerline R2 of the hole. A positioning hole 21 is located at the upper end of the adjustable angle connector 2. The center of the positioning hole 21 is aligned with the center R1 of one end of the semi-circular shape of the elongated arc-shaped hole 22, with the center of that semi-circle lower than the center of the other end. The curvature and length of the centerline R2 are determined based on the deflection angle and illumination height of the lighting equipment.
[0035] In some implementations, such as Figure 3 As shown, the lamp body 1 includes a lamp housing 11, a light source plate 12 with a light source, a reflector 13, and a transparent cover. The light source can be an LED light source, the light source plate 12 can be an aluminum substrate, and the reflector 13 can be a reflector bowl. The transparent cover can be a glass cover. For example, the lamp body 1 has an explosion-proof glass cover 14 on the front, and the reflector bowl 13 is provided inside the integrated lamp housing 11. The light source plate 12 is correspondingly installed inside the housing, and the light emitted by the light source plate 12 shines outward through the reflector bowl. The LED light source is mounted on the aluminum substrate, which is fixed inside the lamp body 1. The reflector bowl is fixed in a fixed position and locked with screws. The glass cover 4 can be made of tempered glass with screen printing. The housing is integrally die-cast.
[0036] To reduce glare from lighting equipment and ensure that all light is focused on the desired area of the road, in some implementations, a reflector is used to redirect the light from the light source, controlling its direction towards a predetermined driving direction. For example, the reflector redirects the light source so that the angle of the light pointing backward does not exceed 5°, and the angle pointing forward is within 70°; in the predetermined cross-sectional direction of driving, the angle of the light pointing upward is within 10°, and the angle pointing downward is within 70°, thus ensuring that all light is focused on the desired area of the road. See [link to relevant documentation]. Figure 3The yellow grid lines indicate this. In practical applications, "rear" and "front" can be determined based on the driving direction, while "above" and "below" refer to the areas above and below the installed lighting equipment.
[0037] In some embodiments, the cables of the lamp body 1 include a main DC 48V low-voltage power supply cable; each cable end of each lamp body 1 is provided with a waterproof connector for connecting the lighting branch cables. The waterproof connector includes a waterproof plug and a wire, the wire being used to connect the cable passing through a through hole on the back of the integrated lamp housing; one end of the waterproof plug connects to the wire, and the other end connects to the waterproof plug of the cable or to an external power source; the two waterproof plugs are quick-connect type, making installation convenient; the waterproof plug is made of nylon material, double-injection molded, with high strength, ensuring a stable connection of the lamp. The branch cables connect to an AC 220V power supply or an AC 220V dimmable power supply (power line carrier dimmable power supply).
[0038] In some implementations, to ensure uniform illuminance distribution, each row of light sources on the light source board uses a different power, with the power increasing incrementally according to a preset driving direction. Multiple lighting devices and multiple lamp bodies are arranged in a straight line and evenly distributed on the road guardrail, thereby achieving good heat dissipation and uniform light emission. This arrangement, combined with the reflector bowls and deflection angles of the lamps, can achieve no shadows during illumination.
[0039] This utility model's lighting equipment can be installed at 4-meter intervals, and its low-position design eliminates glare. Combined with steel or concrete guardrails, it is positioned below the driver's eye level to centrally illuminate the road surface, changing the traditional phenomenon of numerous lighting poles. This saves energy, facilitates future maintenance, and reduces construction costs. Furthermore, the low-position lighting combined with the guardrails creates a linear arrangement of lights along the roadside, providing visual guidance for drivers while minimizing light interference with surrounding buildings and underpasses, thus protecting the integrity and harmony of the bridge's overall landscape.
