Energy-saving street lamp shade

Abstract

This invention relates to the field of energy-saving lamp technology, specifically to an energy-saving street lamp cover, comprising a reflector, a fixing member for fixing a light source inside the reflector, and an annular transparent body on the inner side of the reflector. The fixing member is located above and inside the annular transparent body. In use, the light source is mounted on the fixing member and fixed to the street lamp. When the street lamp is turned on, the reflector reflects the light emitted by the light source. Part of the reflected light passes through the inner and outer sides of the annular transparent body and is emitted onto the road surface through the reflector. The other part of the reflected light, after refracting on the transparent body, gradually overlaps with a portion of the light reaching the road surface, forming a circular bright area. This results in the reflected light gradually dimming and brightening from the center towards the annular bright area, then gradually dimming again, significantly increasing the effective illumination area. Therefore, it can reduce power consumption or the installation density of street lamps, which is beneficial for energy conservation and environmental protection.

Description

Technical Field

[0001] This invention relates to the field of energy-saving lamp technology, specifically to an energy-saving street lamp cover. Background Technology

[0002] Streetlights are common lighting devices. Due to their wide application and large number, their overall power consumption is not negligible. Therefore, people have been researching ways to make streetlights more energy-efficient.

[0003] Existing street light covers are all reflective covers, which reflect the light emitted by the light source onto the road surface through the reflector on top. The reflected light gradually dims from the center to the outside. As a result, people increase the power or increase the installation density of street lights to meet the lighting requirements, which is not conducive to energy conservation and environmental protection. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention provides an energy-saving street lamp cover to solve the aforementioned technical problems.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution:

[0006] An energy-saving street light cover includes a reflector, a fixing member for fixing a light source is provided inside the reflector, and an annular transparent body is provided on the inner side of the reflector. The fixing member is located above the annular transparent body and inside the annular transparent body.

[0007] Preferably, a light-transmitting cover is connected to the lower part of the reflector, and the annular transparent body is provided with a plurality of supports in the circumferential direction. One end of the support is connected to the annular transparent body, and the other end is connected to the light-transmitting cover.

[0008] Preferably, the annular transparent body has circumferential protrusions on its top and bottom surfaces, and the thickness of the protrusions gradually decreases from the center outwards.

[0009] Preferably, the outer surface of the protrusion is spherical.

[0010] Preferably, the support is a transparent support rod.

[0011] Preferably, the bottom of the reflector is provided with a first connecting part, and the top of the light-transmitting cover is provided with a second connecting part; the second connecting part is located inside the first connecting part and is connected to the first connecting part; the first connecting part is provided with a first vent hole, and the second connecting part is provided with a second vent hole corresponding to the position of the first vent hole; the support body is connected to the first connecting part, and the support body is provided with a sealing block, the sealing block blocking the second vent hole inside the light-transmitting cover, and the support body is a bimetallic sheet.

[0012] Preferably, the sealing block is a rubber block.

[0013] Preferably, the first vent is inclined, with its top end closer to the inside of the light-transmitting cover than its bottom end; the second vent is inclined, with its top end closer to the inside of the light-transmitting cover than its bottom end.

[0014] When the energy-saving street light cover provided by this invention is used, the light source is installed on the fixing component and fixed to the street light. After the street light is turned on, the reflector reflects the light emitted by the light source. Part of the reflected light passes through the inner and outer sides of the annular transparent body and is emitted onto the road surface through the light-transmitting cover. The other part of the reflected light shines on the transparent body and is refracted before reaching the road surface, gradually merging with part of the light to form an annular bright area. In this way, after the light reflected by the lamp cover is reflected onto the road surface, the reflected light gradually darkens from the center towards the annular bright area, then brightens, and then gradually darkens again, greatly increasing the effective illumination area. Therefore, the power or the installation density of street lights can be reduced, which is beneficial to energy conservation and environmental protection. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] For examples, please refer to Figure 1 and Figure 2This application provides an energy-saving street light cover, including a reflector 1. A fixing member 2 for fixing a light source is disposed inside the reflector. The fixing member can use existing structures, such as a lamp holder. The light source can use energy-saving bulbs, lamp panels, etc. An annular transparent body 3 is disposed on the inner side of the reflector. The fixing member is located above and inside the annular transparent body. In this application, the orientation (e.g., above) is based on the light cover in its operating state. The transparent body can be made of existing materials, such as glass or transparent resin. Since the streetlights are installed outdoors, this application preferably uses a light-transmitting cover 4 connected below the reflector to achieve a waterproof effect. A typical light-transmitting cover can be threaded or bonded to the reflector. The aforementioned annular transparent body can be fixed to the reflector or to the light-transmitting cover. In this embodiment, the annular transparent body has multiple supports 5 arranged in the circumferential direction. One end of each support is connected to the annular transparent body, and the other end is connected to the light-transmitting cover, thus fixing the annular transparent body to the light-transmitting cover. When fixing, the fixing member and the annular transparent body are preferably concentrically arranged.

[0022] When using the aforementioned energy-saving street light cover, the light source is installed on the fixing component and then fixed to the street light. After the street light is turned on, the reflector reflects the light emitted by the light source. Part of the reflected light passes through the inner and outer sides of the annular transparent body and is emitted onto the road surface through the light-transmitting cover. The other part of the reflected light shines on the transparent body and is refracted before reaching the road surface, gradually merging with part of the light to form an annular bright area. In this way, after the light reflected by the cover is reflected onto the road surface, the reflected light gradually darkens from the center towards the annular bright area, then brightens, and then gradually darkens again. The effective illumination area (the illumination area that meets the lighting requirements) is greatly increased. Therefore, the power or the installation density of street lights can be reduced, which is beneficial to energy conservation and environmental protection.

[0023] In a preferred embodiment, the annular transparent body has multiple protrusions 3-1 circumferentially arranged on its top and bottom surfaces. The thickness of the protrusions gradually decreases from the center outwards. Generally, the outer surface of the protrusions can be spherical. In this way, the protrusions on both sides, together with the transparent body, form a convex lens, which focuses some of the reflected light to form multiple annular false light sources on the road surface. The annular false light sources, after being diffusely reflected by the road surface, improve the brightness and range of the annular bright area, and further expand the effective illumination area.

[0024] In the above embodiments, the support body can be a transparent support rod. As a preferred implementation, see [link to previous embodiment]. Figure 3The reflector has a first connecting part 1-1 at its bottom and a second connecting part 4-1 at its top. The second connecting part is located inside the first connecting part and is connected to it. The first connecting part has a first vent hole 1-2, and the second connecting part has a second vent hole 4-2 corresponding to the first vent hole. The support body is connected to the first connecting part and has a sealing block 6. Generally, the sealing block can be a rubber block. The sealing block blocks the second vent hole inside the light-transmitting cover. The support body is a bimetallic sheet, but other temperature-sensitive deformable sheets can also be used, as long as they can achieve the desired effect. The function is simply to deform when a certain temperature is reached. During manufacturing, the bimetallic strip can be set as an upwardly convex arc shape, and the sealing block is fixed to the upper surface of the bimetallic strip. In this way, when the temperature inside the lampshade is high, the bimetallic strip deforms and bends downward, thereby driving the sealing block to rotate inward. The second vent is connected to the inside of the lampshade. The lampshade dissipates heat through the first and second vents, preventing the lampshade from overheating and damaging the light source. This structure is especially suitable for LED light sources. When the temperature inside the lampshade decreases, the upper metal strip returns to its original shape, and the sealing block seals the second vent, achieving the effect of dust and water protection. The first and second vents are preferably set at an angle, with the top end closer to the inside of the light-transmitting cover than the bottom end.
