Description

Technical Field

[0001] This utility model relates to the field of lighting facilities, specifically to a variable-angle directional lighting street light. Background Technology

[0002] When existing streetlights are illuminating, their lamp heads are often directly facing the ground, and the ends are slightly tilted upwards. Therefore, the light-emitting surface of the lamp head only has an angle in the pitch direction with the sides of the road surface, and there is no angle in the roll direction. When vehicles are driving, they are more sensitive to objects in front of them that are well lit. That is, it is easier for people to notice the side of the object illuminated by the headlights of the vehicle than the side of the object illuminated by the streetlights from top to bottom. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide a variable-angle directional lighting street light that can provide good illumination of the lane.

[0004] To address the above problems, the following technical solution is provided: a variable-angle directional lighting street light, including a light pole, the top of which is provided with at least one set of light arms extending outward along the radial direction of the light pole, each set of light arms having a light head at its end; the light arms are provided with a pitch adjustment mechanism for controlling the pitch angle of the light head and a roll adjustment mechanism for controlling the roll angle of the light head; when there are multiple sets of light arms, they are arranged at intervals along the circumferential direction of the light pole.

[0005] The present invention is further configured such that when there are two sets of lamp arms, they are arranged at 180-degree intervals along the circumferential direction of the lamp post and the lamp post is installed in the middle of the two-way lane. After the lamp head adjusts the roll angle, the illumination direction is from the rear of the car traveling in the lane to the front of the car.

[0006] The present invention is further configured such that when there are three sets of lamp arms, they are arranged at 180-degree intervals along the circumference of the lamp pole; when there are four sets of lamp arms, they are arranged at 90-degree intervals along the circumference of the lamp pole; and the lamp pole is installed at the center of the intersection roundabout; after the lamp head adjusts the roll angle, the illumination direction is from the rear of the car in the roundabout to the front of the car.

[0007] The present invention is further configured such that the pitch angle of the lamp head is from 0 degrees in the horizontal state to 30 degrees in the upward state.

[0008] The present invention is further configured such that the roll angle of the lamp head is from 0 degrees when facing the ground to 30 degrees when the rear of the car is shining towards the front of the car.

[0009] The present invention is further configured such that the pitch adjustment mechanism includes a first flange and a second flange, the first flange having bolt holes spaced apart along the circumferential direction of the first flange, and the second flange having fan-shaped holes corresponding to each bolt hole and spaced along the circumferential direction of the second flange; the roll adjustment mechanism includes a third flange and a fourth flange, the third flange having bolt holes spaced apart along the circumferential direction of the third flange, and the fourth flange having fan-shaped holes corresponding to each bolt hole and spaced along the circumferential direction of the fourth flange; the bolt holes and the fan-shaped holes are connected by fixing bolts.

[0010] The present invention is further configured such that sealing rings are provided between the first flange and the second flange and between the third flange and the fourth flange; the power cord is connected to the lamp holder via the lamp post, the lamp arm and the first flange, the second flange, the third flange and the fourth flange on the lamp arm.

[0011] The present invention is further configured such that the lamp holder is equipped with dual-color temperature LED beads.

[0012] In the above structure, with the help of remote control, the color temperature can be adjusted according to the ambient temperature or weather conditions; for example, a warm color temperature is used in a low-temperature environment and a cool color temperature is used in a high-temperature environment to improve sensory comfort; and a cool color temperature is used when the road surface is dry and a warm color temperature is used when the road surface is wet to improve the lighting effect.

[0013] The beneficial effects of this utility model are: 1. The pitch adjustment mechanism is used to adjust the pitch angle of the lamp head to control the illumination range in the direction below the lamp head or in the direction of illumination on both sides of the road; the roll adjustment mechanism is used to adjust the roll direction of the lamp head so that it faces the direction of vehicle travel, which helps to improve the illumination effect on objects in the direction of vehicle travel. At the same time, after the lamp head is rolled, it can effectively reduce the glare of the street light in the current lane to the driver at night; since the lamp head of the opposite lane faces the sidewalk of the opposite lane, the lamp head of the opposite lane can also avoid the glare caused by directly shining on the vehicles in the current lane after the roll adjustment; since the lamp head is located at a high position, when the vehicle reaches the front of the roll illumination direction of the lamp head, its light will be reflected by the rearview mirror to the ground. After the vehicle moves away, the angle of refraction becomes smaller and its glare effect will be greatly reduced, so it will not directly affect the observation of the rearview mirror. 2. When there are two sets of light arms with a 180-degree interval, they are suitable for installing streetlights in the green belt in the middle of a two-way lane; when there are three sets of light arms with a 120-degree interval, or four sets of light arms with a 90-degree interval, or more than four sets, they are suitable for installing streetlights in the center of a roundabout at an intersection. 3. Based on the road width, the preferred pitch angle of the lamp head is 10 degrees, 15 degrees, 20 degrees, or 25 degrees; based on the street light spacing and lamp post height, the preferred roll angle of the lamp head is 10 degrees, 15 degrees, 20 degrees, or 25 degrees, wherein the street light spacing is directly proportional to the roll angle, and the lamp post height is inversely proportional to the roll angle. 4. Dual-color temperature LED beads, combined with remote control, can adjust the color temperature according to the ambient temperature or weather conditions; for example, a warm color temperature is used in low-temperature environments and a cool color temperature is used in high-temperature environments to improve sensory comfort; and a cool color temperature is used when the road surface is dry and a warm color temperature is used when the road surface is wet to improve the lighting effect.

The top of the lamp post 10 is provided with at least one set of lamp arms 20 extending radially outward along the lamp post 10. Each set of lamp arms 20 is provided with a lamp head 30 at its end. The lamp arms 20 are provided with a pitch adjustment mechanism 21 for controlling the pitch angle of the lamp head 30 and a roll adjustment mechanism 22 for controlling the roll angle of the lamp head 30. When there are multiple sets of lamp arms 20, they are arranged at intervals along the circumferential direction of the lamp post 10.

[0025] In the above structure, the pitch adjustment mechanism 21 is used to adjust the pitch angle of the lamp head 30 to control the illumination range in the direction below the lamp head 30 or in the direction of illumination on both sides of the road; the roll adjustment mechanism 22 is used to adjust the roll direction of the lamp head 30 so that it faces the direction of vehicle movement, which is beneficial to improve the illumination effect of objects in the direction of vehicle movement. At the same time, after the lamp head 30 is rolled, it can effectively reduce the glare of the street light in the current lane to the driver at night; since the lamp head 30 of the opposite lane faces the direction of the pedestrian crossing of the opposite lane, the lamp head 30 of the opposite lane can also avoid the glare caused by directly shining on the vehicles in the current lane after the roll adjustment; since the lamp head 30 is located at a high position, when the vehicle reaches the front of the direction of the roll illumination of the lamp head 30, its light will be reflected to the ground by the rearview mirror. After the vehicle moves away, the angle of refraction becomes smaller and its glare effect will be greatly reduced, so it will not directly affect the observation of the rearview mirror.

[0026] In this embodiment, when there are two sets of lamp arms 20, they are arranged at 180-degree intervals along the circumferential direction of the lamp pole 10, and the lamp pole 10 is installed in the middle of the two-way lane. After the lamp head 30 adjusts its roll angle, the illumination direction is from the rear of the car traveling in the lane to the front of the car (reference). Figure 1 , Figure 2 , Figure 7 ).

[0030] In this embodiment, the pitch angle of the lamp head 30 ranges from 0 degrees in a horizontal state to 30 degrees in an upward state.

[0031] In the above structure, the preferred pitch angle of the lamp head 30 is 10 degrees, 15 degrees, 20 degrees, or 25 degrees, depending on the road width.

[0032] In this embodiment, the roll angle of the lamp head 30 ranges from 0 degrees when facing the ground to 30 degrees when the rear of the car is shining towards the front.

[0033] In the above structure, based on the street light spacing and the height of the lamp post 10, the roll angle of the lamp head 30 is preferably 10 degrees, 15 degrees, 20 degrees, or 25 degrees, wherein the street light spacing is directly proportional to the roll angle, and the height of the lamp post 10 is inversely proportional to the roll angle.

[0034] In this embodiment, the pitch adjustment mechanism 21 includes a first flange 211 and a second flange 212. The first flange 211 has bolt holes spaced apart along the circumferential direction of the first flange 211, and the second flange 212 has fan-shaped holes corresponding to each bolt hole and spaced along the circumferential direction of the second flange 212. The roll adjustment mechanism 22 includes a third flange 221 and a fourth flange 222. The third flange 221 has bolt holes spaced apart along the circumferential direction of the third flange 221, and the fourth flange 222 has fan-shaped holes corresponding to each bolt hole and spaced along the circumferential direction of the fourth flange 222. The bolt holes and the fan-shaped holes are connected by fixing bolts 23.

[0035] In the above structure, during street light installation, the road width, the height of the light pole 10, and the spacing between street lights determine the pitch angle and roll angle. After adjusting the included angle, the first flange 211 and the second flange 212 are connected and fixed by fixing bolts 23. After adjusting the included angle, the third flange 221 and the fourth flange 222 are connected and fixed by fixing bolts 23.

[0037] In the above structure, the sealing ring (not shown in the figure) can prevent rainwater from entering the lamp arm 20.

[0038] In this embodiment, the lamp head 30 is equipped with dual-color temperature LED beads (not shown in the figure).

[0039] In the above structure, with the help of remote control, the color temperature can be adjusted according to the ambient temperature or weather conditions; for example, a warm color temperature is used in a low-temperature environment and a cool color temperature is used in a high-temperature environment to improve sensory comfort; and a cool color temperature is used when the road surface is dry and a warm color temperature is used when the road surface is wet to improve the lighting effect.
