Description

Technical Field

[0001] This invention relates to the field of lighting equipment technology, and in particular to a night scene lighting strip for building facades and its lighting method. Background Technology

[0002] With the rapid advancement of urban nightscape lighting projects, LED light strips are now commonly used as the core light source for building facade outline lighting and wall ambient lighting. The continuous linear light output of the light strips outlines the building's shape and enhances the nighttime visual effect.

[0003] Currently, most mainstream exterior lighting strips on the market use a fixed profile housing combined with unidirectional LED beads. Patent publication CN219177588U discloses an exterior lighting strip for buildings, whose housing is an integrated U-shaped single-outlet light slot structure. The LED beads are arranged only on the side facing the opening of the housing, and the back of the housing has a fixing buckle for direct adhesion or bolting to the wall. The patent specification clearly states that its design purpose is to achieve unidirectional outlining lighting of the building's contours, and also discloses the following common defects in existing similar exterior lighting strips:

[0004] First, the direction of light strip illumination is completely fixed at the factory and during installation, and it only has a single light output direction, which can only achieve single-sided wall lighting, and its use scenarios are extremely limited.

[0005] Secondly, if the light projection angle needs to be adjusted during the construction phase, the overall installation tilt angle can only be manually adjusted before the light is fixed on the wall. Fine adjustments are made by changing the fixed position of the bracket, which is cumbersome and inefficient.

[0006] Third, once the light strip is completely locked and fixed, there is no secondary adjustment structure. After completion, it is impossible to change the illumination angle according to the actual needs such as the later lighting plan, seasonal lighting effect modification, and interference from the light and shadow of surrounding buildings. If it is necessary to change the light output direction, the entire strip must be removed and re-drilled for fixing, which can easily damage the external wall insulation layer and waterproof coating, resulting in derivative problems such as water seepage and wall damage.

[0007] Existing, limited-edition adjustable light strips can only achieve small-range rotational adjustment in a single direction, still supporting only unidirectional light output and unable to project light into two different directions simultaneously. For example, track-type adjustable linear lights and single-sided rotating light strip structures have LEDs arranged on only one side, and the adjustment mechanism only changes the tilt angle of the light on one side. Although they can change the lighting direction of the light strip, due to their location on the building facade, they are affected by natural wind, which can cause the lighting direction to shift. Furthermore, they do not have bidirectional lighting capabilities. When the building facade has complex lighting requirements such as walls + eaves, columns + glass curtain walls, or double-layer facades, two sets of independent light strips need to be installed and deployed in two different areas, resulting in high material consumption, complex wiring, and a large workload for later maintenance. At the same time, after splicing multiple sets of light strips, the light and shadow connection is discontinuous, the overall sense of layering of the facade at night is poor, and the overall cost of the lighting project is significantly increased.

[0008] Therefore, a new type of building facade night lighting can be adopted to address the shortcomings of existing technologies. Summary of the Invention

[0009] The purpose of this invention is to solve the problems of fixed or unstable lighting angles and single lighting direction in the prior art, and to propose a building facade night scene lighting strip and its lighting method.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A building facade night scene lighting strip includes a lamp tube and a light source module fixedly installed inside the lamp tube, and also includes a reflector module installed outside the lamp tube;

[0012] The lamp tube is elliptical in shape and is fixed to the exterior of the building by two fasteners. The inside of the lamp tube is coated with a reflective coating. The light source module is located at the first focal point of the lamp tube. A light-transmitting component is installed inside the lamp tube to reflect the light emitted by the light source module.

[0013] The reflection module is installed by plugging it into the two fixing buckles. The reflection module is used to reflect the light emitted by the light source module in one direction at multiple angles or in both directions at multiple angles.

[0014] Preferably, the light source module consists of a light-emitting component and an outer cover. The light-emitting component consists of a circuit board and multiple LED beads, each of which is located at the first focal point of the elliptical lamp tube.

[0015] Preferably, the light-transmitting component includes a glass plate fixedly installed inside the lamp tube. The glass plate is located at the second focal point of the elliptical lamp tube. A coating layer is provided on the side of the glass plate away from the first focal point. The coating layer is a semi-transparent metal coating. A light-transmitting opening with the same width as the glass plate is opened on the lamp tube. An arc-shaped sealing plate is fixedly installed at the position of the light-transmitting opening.

[0016] Preferably, the reflective module consists of a transparent reflective tube and its internal reflective components. The reflective tube is designed to be sealed at both ends. A locking post is fixedly installed at one end of the reflective tube, and an elastic telescopic rod is fixedly installed at the other end of the reflective tube. Each of the two fixing buckles has a slot that cooperates with the corresponding locking post and the elastic telescopic rod. A damping plate is fixedly installed between the elastic telescopic rod and the corresponding fixing buckle.

[0017] Preferably, the fixing buckle that cooperates with the elastic telescopic rod is threaded and rotatably installed with a locking bolt that cooperates with the elastic telescopic rod.

[0018] Preferably, the reflective assembly includes two first mirror reflectors rotatably mounted inside the reflective tube. Each of the two first mirror reflectors has a storage slot, and a second mirror reflector is slidably mounted in each of the two storage slots. A spring rod is fixedly installed between each of the two second mirror reflectors and its corresponding storage slot. An adjustment mechanism is installed between the reflective tube and the two second mirror reflectors.

[0019] Preferably, the adjustment mechanism includes a limiting groove formed outside the reflector tube, a limiting slider is slidably installed in the limiting groove, a second magnetic block is fixedly installed on the limiting slider, and a first magnetic block with opposite magnetism to the second magnetic block is fixedly installed on the second mirror reflector plate.

[0020] Preferably, side cover plates are fixedly installed at both ends of the lamp tube, and a sealing rubber plate is fixedly installed on each of the two side cover plates. Splicing pre-reserved holes are provided on both the side cover plates and the sealing rubber plates.

[0021] Preferably, the reflective coating inside the lamp tube is an aluminum-plated film, which is integrally formed with the inner wall of the lamp tube by vacuum evaporation.

[0022] The present invention also provides a lighting method for a building facade night scene lighting strip, including the above-mentioned building facade night scene lighting strip, and further including the following steps:

[0023] S1. First, fix the light tube to both ends with the fixing clips and fix it with adhesive. Then fix the fixing clips to the exterior of the building. The fixing clips are fixed with expansion bolts.

[0024] S2. Next, insert the reflector module between the two fixing clips, and adjust the angle of the reflector module according to the required lighting position;

[0025] S3. The light emitted by the light source module is reflected by the reflective coating inside the lamp tube. Since the light source module is located at the first focal point of the elliptical lamp tube, all the light will be reflected to the second focal point of the lamp tube. The light-transmitting component at the second focal point will shoot the light horizontally out of the lamp tube, so that the light enters the reflective module. After installation, the reflection direction and reflection angle can be changed by adjusting the reflection mode of the reflective module.

[0026] Compared with existing technologies, the advantages of this invention are:

[0027] 1. The light tubes of the exterior night lighting strip of this building are designed with an elliptical structure. All the LEDs of the light source module are uniformly arranged at the first focal point of the ellipse. The inner wall of the light tube is vacuum-deposited with an aluminum reflective coating. According to the optical reflection characteristics of an ellipse, the light emitted by all the LEDs will be reflected by the inner wall and accurately converge to the glass plate at the second focal point. The glass plate is equipped with a semi-transparent metal coating layer to split the light. Some of the light is directly transmitted and some of the light is reflected and refracted, and finally uniformly emitted horizontally from the light-transmitting opening to the external reflective module.

[0028] Compared to traditional single-sided direct-emission light strips, this elliptical dual-focal light path eliminates localized light spots and uneven brightness, resulting in a regular and parallel light output without any scattered or chaotic light. Furthermore, this light path structure eliminates the need for additional lenses, simplifying the design. It ensures a uniform light reference for all light entering the reflection module from the light source, preventing uncontrolled dimming angles due to scattered incident light. This perfectly solves the problem of existing adjustable light strips being affected by wind and assembly errors, significantly improving the stability of facade lighting.

[0029] 2. The exterior night lighting strips of this building are fixed to the building facade by fixing buckles at both ends. The reflector module is installed between the two sets of fixing buckles using a plug-in structure that combines a clip and an elastic telescopic rod. The reflector module can be installed and removed independently without damaging the wall or disassembling the main body of the light tube. The elastic telescopic rod is equipped with a damping plate and a locking bolt. After rotating to adjust the angle of the reflector tube, the locking bolt can be tightened to achieve a wobbly lock. The damping plate counteracts the vibration and displacement caused by outdoor wind.

[0030] Traditional LED strip lights can only have their overall tilt angle adjusted before mounting on the wall. Later relocation requires removal and re-drilling, which can easily damage the waterproof and insulation layers of the exterior wall. This device only requires operating the external reflector module to change the lighting direction, making construction and modification convenient and eliminating the risk of water seepage due to damage to the exterior wall. At the same time, the plug-in structure allows for easy replacement and maintenance of the reflector components later without the need to disassemble the entire LED strip, reducing maintenance costs and adapting to various post-modification scenarios such as adjustments to building lighting schemes and changes to seasonal lighting effects.

[0031] 3. The reflective module of the building's exterior nightscape lighting strip is equipped with two sets of rotatable first mirror reflectors. Each first mirror reflector has a storage slot and a second mirror reflector is slidably mounted on it. A spring rod in the storage slot enables the second mirror reflector to extend and retract adaptively. The sliding limit slider in the same direction drives the mirror to retract and fit together synchronously, so that only light from one side is reflected, realizing multi-angle dimming in a single direction. The sliding slider in the opposite direction causes the two first mirror reflectors to unfold to both sides, and the light is reflected by the upper and lower sets of mirrors respectively, forming two independent light paths, which can be adjusted separately for bidirectional illumination angles.

[0032] Existing traditional light strips only support unidirectional lighting. Multiple sets of light strips are required for composite lighting of walls, eaves, and columns, resulting in cumbersome wiring and light and shadow gaps. This device can illuminate two different facade areas simultaneously with a single light strip, eliminating the need for splicing multiple sets of light strips, reducing material consumption, simplifying wiring, eliminating light and shadow gaps, enhancing the overall sense of layering in the night scene, and significantly reducing the construction and material costs of lighting projects.

[0033] 4. The adjustment mechanism of the building's exterior night lighting strip adopts a magnetically coupled structure consisting of a limiting groove, a limiting slider, a first magnetic block, and a second magnetic block. The limiting groove is located on the outer wall of the reflector tube, with only the external slider in contact with the tube wall. There are no openings or exposed transmission rods, and the sealed structure at both ends of the reflector tube is completely preserved, preventing rainwater and dust from entering the tube and corroding the mirror reflector. The operator only needs to slide the external second magnetic block, relying on the attraction of the opposite magnet to drive the first magnetic block inside the tube to move synchronously, thereby controlling the rotation of the mirror and adjusting the light output angle. The entire process does not require disassembling the sealed housing of the reflector module.

[0034] Traditional adjustable light strips often use external screws and shafts that penetrate the housing. If the seal fails, water can easily get in, causing oxidation of the reflector and short circuits. This magnetic control non-contact adjustment completely avoids the problem of seal damage, making it suitable for long-term outdoor use on building facades and extending the service life of the equipment. At the same time, the external slider adjustment is simple to operate, requiring no professional tools, and construction personnel can quickly complete multi-angle dimming operations.

[0035] 5. The exterior night lighting strips of this building are equipped with side cover plates and sealing rubber plates at both ends of the light tubes. The side cover plates and sealing rubber plates have pre-drilled holes of uniform specifications for splicing, allowing multiple light strips to be quickly spliced ​​and connected in series. The sealing rubber plates fill the splicing gaps to prevent rainwater and moisture from seeping into the interior of the light tubes from the splicing points. The aluminum reflective coating on the inner wall of the light tubes is integrally molded by vacuum evaporation, which has strong adhesion and will not peel off after long-term use. The fixing buckles are designed with independent separate parts, which can be adapted to various building exterior substrates such as flat walls, curved eaves, and columns. The expansion bolts are used for secure fixing.

[0036] Existing conventional light strips lack a dedicated sealing structure at their splicing points, making them susceptible to water ingress and damage to the light source when used outdoors, and they cannot be adapted to irregular building outlines. This device features segmented modular splicing with multi-layered sealing protection, resulting in a higher level of waterproofing and dustproofing. It allows for continuous deployment of lighting along long-distance building outlines without any issues. The light source module, lamp tube, and reflector module can be disassembled and replaced individually, eliminating the need to scrap the entire light strip in case of partial damage, further reducing subsequent maintenance and consumable costs.

Detailed Implementation

[0055] 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.

[0056] Example 1: Refer to Figures 1-8 , Figures 10-11 A building facade night scene lighting strip includes a lamp tube 2 and a light source module 1 fixedly installed inside the lamp tube 2, and also includes a reflector module 3 installed outside the lamp tube 2;

[0057] The lamp tube 2 is elliptical and is fixed to the building facade by two fixing buckles 10. The inside of the lamp tube 2 is coated with a reflective coating. The light source module 1 is located at the first focal point of the lamp tube 2. The lamp tube 2 is equipped with a light-transmitting component to reflect the light emitted by the light source module 1.

[0058] The light source module 1 consists of a light-emitting component 6 and an outer cover 7. The light-emitting component 6 consists of a circuit board 9 and multiple LED beads 8. Each LED bead 8 is located at the first focal point of the elliptical lamp tube 2.

[0059] The light-transmitting component includes a glass plate 14 fixedly installed inside the lamp tube 2. The glass plate 14 is located at the second focal point of the elliptical lamp tube 2. A coating layer 15 is provided on the side of the glass plate 14 away from the first focal point. The coating layer 15 is a semi-transparent metal coating. A light-transmitting opening with the same width as the glass plate 14 is opened on the lamp tube 2. An arc-shaped sealing plate 16 is fixedly installed at the position of the light-transmitting opening.

[0060] The glass plate 14 is positioned at the second focus of the ellipse to receive all the converging beams. Combined with the semi-transparent metal coating layer 15, it achieves the function of beam splitting. Part of the light directly penetrates the glass plate 14 and is output outward, while the other part of the light is reflected and refracted by the coating layer 15 for secondary use, which greatly improves the light energy utilization rate and solves the problems of light energy waste and insufficient brightness of traditional light strips.

[0061] The width of the light-transmitting opening is perfectly matched with the glass plate 14 to prevent light from leaking out from the gap. The arc-shaped sealing plate 16 seals the light-transmitting opening to prevent rainwater and dust from entering the lamp tube 2 and to protect the internal light path and light source.

[0062] Ordinary light strips lack a beam-splitting and converging structure, resulting in severe light dispersion and rapid brightness decay when used for long-distance facade lighting. This light-transmitting component integrates the chaotic beam into a horizontal parallel beam, extending the light range. The arc-shaped sealing plate 16 fits snugly against the arc-shaped outer wall of the light tube 2, ensuring a higher degree of sealing and preventing water leakage and fogging during long-term outdoor use. This guarantees a clean internal light path and a stable, well-defined beam output, providing a uniform incident light source for bidirectional, multi-angle dimming.

[0063] The device employs an elliptical lamp tube 2 paired with a dual-focus optical path architecture. The lamp tube 2 uses an elliptical shape as the core optical carrier, and the elliptical geometric characteristics are the basic design for this device to achieve uniform parallel light output.

[0064] The fixing buckle 10 is set up independently and is specifically responsible for the connection and fixing of the light tube 2 to the building wall. It separates and fixes the light tube body and the dimming reflection module 3. In the future, only the reflection module 3 needs to be removed to adjust the light. There is no need to remove the entire light tube 2. This solves the pain point of traditional light strips that require wall removal and drilling for overall fixing and adjustment.

[0065] The light source module 1 is arranged at the first focus of the ellipse. The vacuum-plated aluminum reflective coating on the inner wall of the lamp tube 2 can reflect all the light without loss. After reflection, all the light automatically converges to the light-transmitting component at the second focus, avoiding the problems of light scattering and uneven brightness of ordinary straight tube light strips.

[0066] The light-transmitting component is located at the second focal point and is responsible for converging and splitting the light to output a regular parallel beam. This provides a stable and uniform incident light source for the external reflection module 3, fundamentally solving the defects of existing adjustable light strips, such as messy light and angle deviation due to wind interference, and greatly improving the stability of outdoor night scene lighting.

[0067] Both ends of the lamp tube 2 are fixedly installed with side cover plates 4, and a sealing rubber plate 5 is fixedly installed on each of the two side cover plates 4. Splicing reserved holes are opened on both the side cover plates 4 and the sealing rubber plate 5.

[0068] The lamp tube 2 is equipped with a double sealing structure of side cover plates 4 and sealing rubber plates 5 at both ends. The side cover plates 4 provide rigid end sealing support, and the sealing rubber plates 5 rely on elasticity to fill the splicing gaps. When multiple light strips are spliced ​​together in series, water vapor and rainwater cannot seep into the lamp tube 2 from the splicing gaps, solving the defects of traditional light strips that have no seal at the splicing points and are prone to water ingress and burning of the light source outdoors. The side cover plates 4 and sealing rubber plates 5 are uniformly opened with splicing reserved holes of the same specification. The standardized hole positions can quickly complete the splicing of multiple light strips from end to end, which is suitable for continuous lighting construction of long building outlines. No additional customized adapter accessories are required, which improves on-site assembly efficiency.

[0069] The split-type end sealing structure can be disassembled individually. In the event of a single light source failure, only the corresponding two ends of the light strip are disassembled without damaging the entire lighting circuit. The sealing rubber plate 5 has aging resistance and UV resistance properties. It will not harden or crack after long-term outdoor exposure, and will continue to maintain its sealing and protective performance, thus expanding the applicability of the light strip to various outdoor building exterior wall scenarios.

[0070] The reflective coating inside lamp tube 2 is an aluminum-plated film, which is integrally formed with the inner wall of lamp tube 2 through vacuum evaporation. The inner wall of lamp tube 2 uses a vacuum-evaporated integrally formed aluminum-plated film as the reflective coating. The vacuum evaporation process allows the aluminum-plated film to be tightly bonded to the tube wall, with extremely strong adhesion. It will not peel or fall off under long-term light exposure and alternating hot and cold environments. Compared with traditional adhesive reflective films, the reflection efficiency is stable and durable. The aluminum-plated material has a high reflectivity, which can achieve more than 90% light reflection, greatly reducing light energy loss. The lighting brightness is higher with 8 lamp beads of the same power, which is energy-saving and environmentally friendly.

[0071] Ordinary LED strips often have reflective films that are prone to peeling or falling off, leading to localized reflective failures after a period of use, resulting in bright and dark patches that affect the lighting effect of the facade. This one-piece molded reflective coating completely adheres to the inner wall of the ellipse without gaps or dead angles. Each beam of light from the LED beads can be completely reflected and converged to the second focal point, ensuring a stable and uniform light path. This completely solves the technical defects of uneven light spots and poor dimming effect caused by reflective layer failure.

[0072] Example 2: This example differs from Example 1 in that: (Refer to...) Figures 1-9 , Figures 12-16 The reflection module 3 is installed by plugging in the two fixing buckles 10. The reflection module 3 is used to reflect the light emitted by the light source module 1 in one direction at multiple angles or in both directions at multiple angles.

[0073] The reflective module 3 consists of a transparent reflective tube 17 and its internal reflective components. The reflective tube 17 is designed to be sealed at both ends. A locking post 18 is fixedly installed at one end of the reflective tube 17, and an elastic telescopic rod 19 is fixedly installed at the other end of the reflective tube 17. Each of the two fixing buckles 10 has a slot that cooperates with the corresponding locking post 18 and elastic telescopic rod 19. A damping plate 20 is fixedly installed between the elastic telescopic rod 19 and the corresponding fixing buckle 10.

[0074] The reflector tube 17 adopts a completely sealed transparent structure at both ends, preferably made of acrylic material. The internal reflective components are completely isolated from the outside world, preventing rainwater, dust, and insects from entering the tube and corroding the mirror surface. The reflective effect does not diminish even after long-term outdoor use. One end has a locking post 18, and the other end has an elastic telescopic rod 19, which forms a telescopic plug-in structure. The elastic telescopic rod 19 can extend and retract slightly to fit the mounting tolerance of the fixing buckle 10, making assembly convenient and without jamming. The damping plate 20 is placed between the elastic telescopic rod 19 and the fixing buckle 10. After rotating to adjust the angle of the reflector tube 17, it increases the frictional resistance, counteracts the continuous vibration of outdoor natural wind, prevents the angle of the reflector tube 17 from shifting, and solves the problem of the existing adjustable light strips being affected by wind and causing the illumination direction to deviate.

[0075] Traditional dimming light strips have no damping lock, causing the mirror to sway and the light and shadow to drift continuously in windy weather, resulting in unstable lighting effects. The sealed reflector tube 17 does not require frequent disassembly and maintenance, greatly reducing mirror oxidation and dust accumulation. The transparent tube transmits light without loss and does not block internal reflected light, ensuring stable and clear light output when dimming at multiple angles.

[0076] The fixing buckle 10 that cooperates with the elastic telescopic rod 19 is threaded and rotatably installed with a locking bolt 13 that cooperates with the elastic telescopic rod 19. This design can effectively lock the elastic telescopic rod 19 and prevent the reflector tube 17 from shifting.

[0077] The reflective assembly includes two first mirror reflectors 22 rotatably mounted inside the reflective tube 17. Each of the two first mirror reflectors 22 has a storage slot. Each of the two storage slots has a second mirror reflector 23 slidably mounted inside it. Each of the two second mirror reflectors 23 is fixedly mounted with a spring rod between it and the corresponding storage slot. An adjustment mechanism is installed between the reflective tube 17 and the two second mirror reflectors 23.

[0078] The reflective component adopts a double-layer telescopic mirror combination. The first mirror reflector 22 is the main reflective component, and the second mirror reflector 23 is slidably assembled in the built-in storage groove. The spring rod continuously provides the retraction force. When retracted, the second mirror reflector 23 is automatically stored in the groove without interfering with the unidirectional lighting path. The two first mirror reflectors 22 can be retracted simultaneously or extended to both sides. In the retracted state, only a single beam of light is reflected, realizing multi-angle lighting on a single facade, and some light is horizontally direct. After being extended, the upper and lower sets of first mirror reflectors 22 reflect light independently, forming a bidirectional lighting path. One light strip can adapt to the composite lighting needs of double-layer and irregular facades, solving the drawbacks of traditional light strips that only emit light in one direction and require multiple sets of equipment for multi-area lighting.

[0079] The double-layer telescopic mirror increases the range of reflection adjustment, enabling large-angle tilt and dimming, while the spring rod ensures smooth and unobstructed sliding of the mirror.

[0080] The adjustment mechanism includes a limiting slide groove 21 opened outside the reflector tube 17, a limiting slider 26 slidably installed in the limiting slide groove 21, a second magnetic block 25 fixedly installed on the limiting slider 26, and a first magnetic block 24 with the opposite magnetism to the second magnetic block 25 fixedly installed on the second mirror reflector plate 23.

[0081] The adjustment mechanism is externally controlled without contact, eliminating the need to open holes and damage the sealed structure of reflector tube 17. It meets the dual requirements of wide-angle dimming and outdoor waterproof protection, with natural transition of light and shadow without obvious light and dark boundaries, resulting in better night scene visual effects.

[0082] The adjustment mechanism adopts a magnetic coupling non-contact transmission design, with a limiting groove 21 only opened on the outer wall of the reflector tube 17. There are no through holes in the tube wall, which completely preserves the sealed and waterproof structure of the reflector tube 17 and eliminates the problems of water leakage and mirror oxidation caused by the opening of the traditional screw through-type adjustment mechanism. The operator only slides the external limiting slider 26, and the attraction force of the opposite magnet drives the first magnetic block 24 inside the tube to move synchronously, thereby controlling the second mirror reflector 23 and the first mirror reflector 22 to rotate synchronously and complete the switching of the illumination angle. The operation is simple and intuitive and does not require disassembling the reflector tube.

[0083] Ordinary adjustable light strips have an adjustment shaft that runs through the tube body. After long-term aging of the sealant, water can seep in, causing the mirror surface to rust and significantly reducing its reflectivity. This magnetic control structure has no internal or external connecting transmission parts, resulting in a higher level of waterproofing and dustproofing, making it suitable for building facades exposed to the elements year-round. The limiting groove 21 restricts the sliding stroke of the slider, preventing the second mirror reflector 23 and the first mirror reflector 22 from overtraveling and getting stuck. The magnetic attraction of the first magnetic block 24 and the second magnetic block 25 is stable. During the sliding process, the second mirror reflector 23 and the first mirror reflector 22 are synchronized, and the adjustment angles of the second mirror reflector 23 and the first mirror reflector 22 on both sides are consistent. When illuminating in both directions, the light is symmetrical and uniform, and there will be no unilateral light and shadow deviation.

[0084] The specific operating steps of this device are as follows:

[0085] Installation and adjustment of reflector tube 17: Rotate reflector tube 17 so that the two first mirror reflector plates 22 and the second mirror reflector plate 23 inside reflector tube 17 are horizontal. In the initial state, the two first mirror reflector plates 22 are in contact, and then the elastic telescopic rod 19 is locked by locking bolt 13.

[0086] Horizontal and vertical arbitrary angle illumination adjustment: Simultaneously rotating the two second magnetic blocks 25 in the same direction, under the effect of opposite poles attracting each other, will drive the two first magnetic blocks 24 to move, thereby driving the two second mirror reflectors 23 to rotate simultaneously. The two first mirror reflectors 22 will also rotate synchronously with the corresponding second mirror reflectors 23, thereby changing the angle of the first mirror reflectors 22 and the second mirror reflectors 23. The light emitted by the lamp bead 8 is emitted from the first focal point of the lamp tube 2, and is reflected by the reflective coating to the glass plate 14 at the second focal point. Some of the light is reflected by the coating and passes through the glass plate 14 and the back of the coating layer 15, while the other part is reflected directly by the coating to the front of the coating layer 15. The front of the coating layer 15 will reflect the light. Since the coating layer 15 and the glass plate 14 are curved, the light will be emitted horizontally from the light-transmitting hole. The emitted light will pass through the reflector tube 17. Initially, the first mirror reflector 22 is horizontal, so the light will be emitted horizontally.

[0087] Once the two first mirror reflectors 22 rotate, since the first mirror reflectors 22 are located in the middle of the reflector tube 17, the light in the upper half will be reflected by the first mirror reflectors 22. The angle of light reflection can be changed by adjusting the angle of the first mirror reflectors 22, while the light in the other half will still be emitted horizontally.

[0088] When the two second magnets 25 are moved in opposite directions, the two first mirror reflectors 22 rotate to both sides (due to the rotation of the first mirror reflector 22 and the second mirror reflector 23, the distance between the first mirror reflector 22 and the first magnet 24 will decrease, causing the second mirror reflector 23 to slide in the storage groove and be reset by the spring rod), and are in an unfolded state. At this time, after the light is emitted from the light-transmitting hole, it will be reflected by the two first mirror reflectors 22. The light is divided into two parts, and the direction of the upper and lower beams of light can be adjusted by adjusting the first mirror reflectors 22, so as to achieve bidirectional multi-angle illumination.

[0089] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
