Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of lighting street lamps, and in particular to a short-range anti-glare low-pole LED street lamp. Background Art
[0002] Glare refers to a visual condition characterized by visual discomfort and reduced visibility caused by unsuitable brightness distribution or extreme brightness contrast in space or time. LED lights typically have high brightness. Looking directly at an overly bright LED light source can cause temporary dizziness or blurred vision. Methods to alleviate glare caused by LED lights include: adjusting light intensity and avoiding looking directly at overly bright LED lights; However, due to the height of low-pole street lights, the light source is closer to pedestrians or vehicles, which will inevitably affect people's eyes and cause glare problems.
[0003] The above information disclosed in this Background section is only for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not form the prior art that is already known to a person of ordinary skill in the art. Summary of the Invention
[0004] The purpose of the present invention is to design a low-pole street lamp that converts the high-brightness point light source emitted by an LED lamp into a planar light source, thereby preventing the glare problem from occurring, so as to solve the above-mentioned shortcomings in the technology.
[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a short-range anti-glare low-pole LED street lamp, comprising a lamp pole and a lamp holder mounted on the lamp pole, the lamp holder comprising a lamp housing for accommodating a light source, a plurality of reflective covers having overlapping central axes mounted on the bottom of the lamp housing, the plurality of reflective covers increasing in vertical height from the inside to the outside, a light-transmitting member fixedly mounted on the bottom of the outermost reflective cover, a reflective member and a refractive member fixedly mounted on the top surface of the light-transmitting member, the reflective member being located outside the refractive member, and a through hole being formed on the top of the reflective member; Part of the light emitted by the light source passes through the through hole and the refraction member to the light-transmitting member, and the other part of the light passes through the surface of the reflector and is reflected to different reflective cover surfaces, and finally reflected to pass through the light-transmitting member, turning the point light source into a planar light source.
[0006] Preferably, the reflector and the plurality of reflective covers are truncated cone-shaped, and the angle between the busbars of the reflector and the reflective cover and the horizontal plane is 45°. The purpose of setting the 45° angle is to ensure that the light emitted from the reflective cover to the light-transmitting member is as perpendicular to the light-transmitting member as possible.
[0007] Preferably, the surfaces of the reflector and the plurality of reflective covers are all coated with a mirror, and the mirror is used to reflect light.
[0008] Preferably, among the plurality of reflective covers from the inside to the outside, the bottom diameter of the inner reflective cover is the same as the top diameter of the adjacent outer reflective cover.
[0009] Preferably, the vertical height differences between two adjacent reflectors from the inner to the outer sides are the same.
[0010] Preferably, the plurality of reflective covers are provided with a plurality of light-transmitting slots distributed in an array, the number of light-transmitting slots on the reflective covers increases from the inner to the outer, and the outermost reflective cover has no light-transmitting slots.
[0011] Preferably, the widths of the light-transmitting grooves on the plurality of reflective covers gradually decrease from the inside to the outside.
[0012] Preferably, the lamp housing comprises a hollow tube for accommodating the light source and a circular ring fixedly mounted at the bottom of the hollow tube, and the inner wall of the hollow tube is mirror-plated.
[0013] Preferably, a plurality of connecting plates are fixedly installed on the top of one of the reflective covers, the connecting plates pass through the circular ring and are slidably connected to the circular ring, a transmission ring is fixedly installed on the top of the connecting plates, a spring is installed between the transmission ring and the circular ring, the hollow tube passes through the transmission ring, and the remaining reflective parts are fixedly connected to the bottom surface of the circular ring.
[0014] Preferably, the light-transmitting component and the refractive component are both made of frosted glass, which can refract and reflect to make the light more uniform.
[0015] In the above technical solution, the technical effects and advantages provided by the present invention are: The cooperation between the reflective element, the refractive element and the multiple reflective covers of the present invention can convert the high-brightness point light source emitted by the LED light source into a surface light source with uniform brightness, thereby solving the problem of temporary dizziness caused by overly bright LED light sources and preventing glare. The present invention provides a plurality of light-transmitting grooves distributed in an annular array on a plurality of reflectors, thereby dividing a portion of the light originally reflected by the inner reflectors and reflecting it to the outer reflectors. This prevents the inner circle of the formed planar light source from being bright and the outer circle from being dark, thereby ensuring the uniformity of the brightness of the planar light source. At the same time, the present invention uses the light-transmitting parts and reflective parts of the frosted glass material components to cause diffuse reflection of light when passing through, further making the light emitted by the street lamp softer and not as glaring as the light emitted by the point-shaped LED lamp; The present invention can also rotate the lamp housing to move one of the reflective covers downward, blocking most of the light from passing through it and irradiating the reflective cover outside it, thereby converging the light, reducing the size of the planar light source, and increasing the brightness. It can be designed to match the height of the lamp pole. If the lamp pole is low, a large planar light source is used. If the lamp pole is high, a small planar light source is used to concentrate the light and ensure visibility of the road surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.
[0020] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.
[0021] The present invention provides Figure 1-6The illustrated embodiment of a short-range anti-glare low-pole LED street light comprises a lamp post 1 and a lamp holder, the lamp holder comprising a lamp housing 2, the lamp holder being fixedly connected by a hollow tube 2a and a circular ring 2b, the hollow tube 2a being threadedly connected to the lamp post 1, and a high-brightness LED light source being arranged inside the hollow tube 2a, a plurality of truncated cone-shaped reflectors 3 with overlapping central axes being mounted at the bottom of the circular ring 2b, a light-transmitting member 4 made of frosted glass being fixedly mounted at the bottom of the outermost reflector 3, a frosted glass refractive member 6 with a central axis coinciding with the reflector 3 being fixedly mounted at the top of the light-transmitting member 4, and a reflector 5 having a through hole 7 at the top, the angle between the busbars of the truncated cone and the reflector 5 and the horizontal plane being 45°, the surfaces of the reflector 5 and the reflector 3 being both mirror-coated, the surfaces being smooth enough to reflect light. Light can also be transmitted. The height of these reflective covers 3 gradually increases from the inside to the outside. The increase can be consistent or inconsistent, and the bottom diameter of the internal reflective cover 3 is the same as the top diameter of the adjacent external reflective cover 3. These reflective covers 3 are provided with multiple light-transmitting grooves 8, which are distributed in a circular array. The closer to the external reflective cover 3, the smaller the width of the light-transmitting groove 8, and the closer to the internal reflective cover 3, the larger the width of the light-transmitting groove 8. A plurality of mirror connecting pieces 9 are fixedly installed on the top of one of the reflective covers 3. A transmission ring 10 is fixedly installed on the top of these connecting pieces 9. The transmission ring 10 is penetrated by the hollow tube 2a. A spring 11 is provided between the transmission ring 10 and the circular ring 2b. The top of the hollow tube 2a is threadedly connected to the top of the lamp pole 1; In actual use, the LED light source will emit high-brightness light. Most of these lights will be vertically directed toward the reflector 5 in the hollow tube 2a. The light in the center will pass through the through slot and be directed toward the refractive element 6. When passing through the reflector 5, reflection and refraction will occur, so that the light will be dispersed and directed toward the light-transmitting element 4. Figure 5 As shown, the remaining light will be emitted vertically to the surface of the reflector 5. The light reflected closer to the upper part of the reflector 5 will be directly reflected to the surface of the reflector 3 closer to the inside. The light not reflected by the inner reflector 3 will reach the surface of the next reflector 3 outside, until it reaches the surface of the outermost reflector 3 and is reflected. Finally, the light passes through the light-transmitting member 4 to form a planar light source. At the same time, due to the presence of the light-transmitting groove 8, Figure 6 As shown, part of the light will be reflected toward the light-transmitting member 4 when it strikes the surface of the reflector 3, and another part of the light will pass through the reflector 3 and strike the adjacent external reflector 3. Since the width of the light-transmitting grooves 8 on the reflector 3 decreases from the inner to the outer part, this part of the light will be blocked by the adjacent external reflector 3 and reflected, allowing the remaining light to pass through its own light-transmitting grooves 8 until the light finally strikes the surface of the outermost reflector 3. This prevents the innermost reflector 3 from reflecting more light and the outermost reflector 3 from reflecting less light, resulting in the light emitted from the light-transmitting member 4 being bright in the middle and dark outside, thereby ensuring the formation of a planar light source with uniform brightness as much as possible. If you do not want the surface light source to be too large and want to shrink the surface light source to increase the local brightness, you can rotate the lamp housing 2 to drive the hollow tube 2a to rotate into the lamp pole 1, thereby pushing the transmission ring 10 to compress the spring 11. The transmission ring 10 will drive the connecting piece 9, and the connecting piece 9 will drive the reflector 3 connected to it to move toward the light-transmitting part 4, thereby gradually blocking the light reflected by the reflector 3 outside it, and trying to concentrate the light in the circle with a smaller diameter, thereby increasing the local brightness and shrinking the surface light source.
