Description

Technical Field

[0001] This utility model relates to the field of building facade lighting technology, and in particular to a physical adjustment system for built-in lighting in UHPC concrete facade. Background Technology

[0002] In building facade design, combining UHPC (Ultra-High Performance Concrete) with lighting has become an important means of creating unique visual effects. However, traditional methods of adjusting lighting brightness mainly rely on voltage regulation, which has significant drawbacks when applied to UHPC-embedded lighting. Voltage regulation not only subjectes the internal electronic components of the lamps to unstable current surges, accelerating component aging, but also makes lamp maintenance extremely difficult due to the high density of UHPC concrete. When a lamp malfunctions, repairs often require damaging part of the concrete structure, which not only increases maintenance costs but may also affect the overall structural integrity and aesthetics of the building facade.

[0003] In existing technologies, voltage regulation methods have a particularly significant impact on the lifespan of luminaires. Due to the limited heat dissipation conditions in UHPC concrete environments, the wear and tear on electronic components caused by voltage fluctuations is more pronounced. Furthermore, traditional regulation methods cannot meet the precise control requirements of building facade lighting for light angle and illumination range, limiting the diversity of lighting effects. In addition, when it is necessary to adjust the direction or brightness of the light, traditional electrical regulation methods struggle to achieve precise physical control and cannot avoid electrical interference to the luminaires themselves.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] In existing technologies, building facade lighting adjustment commonly employs voltage control, adjusting the brightness of the luminaires by changing the input voltage. This adjustment method causes the internal electronic components of the luminaires to operate in an unstable state for extended periods, accelerating component aging. For luminaires embedded in UHPC concrete structures, the enclosed environment exacerbates heat dissipation difficulties, further shortening the luminaire's lifespan. Moreover, when a luminaire malfunctions, the high density of UHPC material necessitates repair work that damages the concrete structure, increasing repair costs and causing damage to the building's exterior.

[0031] To address the aforementioned issues, researchers discovered irreversible electronic losses in voltage regulation methods and explored the feasibility of physical shielding. By analyzing the light propagation path, they proposed the idea of ​​installing a movable shielding structure on the outside of the lamp. After multiple experimental verifications, it was found that horizontal shielding structures were prone to uneven light spots, ultimately leading to the selection of a vertical shielding plate combined with angle adjustment. To solve the problem of shielding plate movement stability, a double-point fixed L-shaped mounting structure was designed to ensure that mechanical components do not shift during adjustment.

[0032] Therefore, as Figure 1 , Figure 2 and Figure 3 As shown, this application proposes a lighting adjustment system including a building steel structure 100 and a UHPC exterior wall panel 200. L-shaped mounting plates 300 are respectively provided at the upper and lower ends of the lighting trough plate 201 at the front end of the UHPC exterior wall panel 200. Vertical lighting units 400 and adjustable shielding plates 500 that can be opened and closed on the outside are provided on the mounting plates.

[0033] Among them, the building steel structure 100 refers to a load-bearing frame composed of steel beams and columns, which can be formed by welding hot-rolled H-beams or box-shaped steel components. The UHPC exterior wall panel 200 refers to a precast ultra-high performance concrete panel, which can be prepared by casting in molds and then curing at high temperatures. The lighting trough panel 201 refers to a groove structure arranged inwards at the front end of the UHPC exterior wall panel 200, formed by composite processing of UHPC panels. The L-shaped mounting plate 300 refers to a metal support component with right-angle bends, which can be made by stamping stainless steel plates into a 90-degree angled structure. The lighting unit 400 refers to a linearly arranged lighting device, which can be composed of LED modules and a heat dissipation substrate. The adjustable shielding plate 500 refers to a light-shielding component with a rotating function, which can be made of anodized aluminum plates and adjusted at an angle via a hinge mechanism.

[0034] Specifically, the building steel structure 100 provides an installation base for the UHPC exterior wall cladding 200, which is fixed to the steel structure surface via pre-embedded connectors. The lighting trough 201 forms a light guiding channel, and the L-shaped mounting plates 300 at its upper and lower ends constitute a double-point support system. The lighting unit 400 is vertically installed between the two L-shaped mounting plates 300. An adjustable baffle 500 is hinged to the outer edge of the L-shaped mounting plate 300; when closed, the adjustable baffle 500 covers the light-emitting surface of the lighting fixture, and when open, it forms a trapezoidal light-transmitting area. Figure 5 As shown, when brightness needs to be adjusted, the operator rotates the adjustable baffle 500 to change its relative angle with the luminaire unit 400, thereby achieving linear control of light intensity by adjusting the shading area. The symmetrical layout of the L-shaped mounting plate 300 keeps the rotation axis of the adjustable baffle 500 vertical, avoiding horizontal displacement during adjustment that could cause light spot distortion.

[0035] Compared to existing technologies, traditional voltage regulation relies on altering the operating state of electronic components, while this solution achieves brightness control through physical shielding, eliminating the impact of voltage fluctuations on the luminaire. Existing technologies require structural damage to maintain recessed luminaires; this solution places the adjustable shield 500 externally within the lighting trough plate 201. Maintenance only requires removing the adjustable shield 500 to expose the inner L-shaped mounting plate 300 and the luminaire unit 400. Traditional single-point fixing methods are prone to causing loosening of the adjustment mechanism, while this solution uses upper and lower double L-shaped mounting plates to form a stable support system.

[0036] Through the above technical solution, this application achieves stable operation of the luminaire under constant voltage, avoiding accelerated aging of electronic components caused by voltage fluctuations. The mechanical adjustment mechanism is separated from the luminaire, eliminating the need to damage the UHPC concrete structure during maintenance. The angle of the baffle plate and the light-transmitting area form a linear correspondence, achieving stepless brightness control precision. The double-support structure ensures stable movement trajectory of the baffle plate during adjustment, maintaining uniform light distribution.

[0037] In some of these embodiments, such as Figure 1 and Figure 2 As shown, this application further proposes that several UHPC exterior wall panels 200 are sequentially spliced ​​together, with the opening of the front lighting channel plate 201 of one UHPC exterior wall panel 200 facing inwards and directly opposite the rear end of another UHPC exterior wall panel 200. Specifically, during installation, the opening of the lighting channel plate 201 of the front panel faces inwards towards the building. When the lighting unit 400 is activated, the light, through the cone-shaped illumination area formed by the opening, completely covers the rear end joint area of ​​the adjacent panels, eliminating the triangular dark area caused by traditional staggered splicing.

[0038] In some of these embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, this application further proposes that L-shaped mounting plates 300 are respectively provided in the first slot 202 at the lower end and the second slot 203 at the upper end of the light slot plate 201. The bottom of the first slot 202 and / or the top of the second slot 203 are respectively provided with track grooves 204 for limiting the opening and closing angle of the adjustable baffle plate 500, and the center of the track groove 204 is provided with a through hole for installing the adjusting screw 501.

[0039] The first slot 202 and the second slot 203 refer to the installation spaces provided at the upper and lower ends of the light trough plate 201, which can be implemented using a U-shaped slot structure to accommodate the L-shaped mounting plate 300 and provide mechanical support. The track slot 204 refers to the fan-shaped groove provided at the bottom or top of the inner side of the light trough plate 201. The bottom of the adjustable baffle plate 500 is correspondingly set in the fan-shaped groove, and the center of the fan-shaped groove coincides with the axis of the adjusting screw, which is used to constrain the rotation range of the baffle plate.

[0040] Specifically, the L-shaped mounting plate 300 is fixed in the upper and lower slots of the light trough plate 201, forming a two-way support structure. The fan-shaped limiting surface of the track groove 204 matches the movement trajectory of the adjustable baffle 500. When the adjusting screw 501 drives the adjustable baffle 500 to rotate, the side wall of the track groove 204 contacts and limits the edge of the baffle, so that its opening and closing angle is precisely controlled within a predetermined range.

[0041] Through the above technical solution, this application achieves mechanical limiting of the opening angle of the adjustable baffle 500, avoiding structural damage caused by excessive rotation, while ensuring smooth adjustment through coaxial positioning design. This structure allows for maintenance of the adjustment mechanism without disassembling the concrete mounting plate, for example, by directly replacing the adjusting screw through a perforation, without damaging the surrounding structure. After the physical limiting mechanism replaces voltage regulation, the lighting unit 400 always operates at the rated voltage, reducing the risk of aging of electronic components.

[0042] In some of these embodiments, such as Figure 3 As shown, the L-shaped mounting plate 300 used in this application has an overall L-shaped plate structure. A cylindrical hinge 301 is provided on the inner side wall of one end. A circular through hole is opened on the cylindrical hinge 301. The two cylindrical hinges 300 at the upper and lower ends are installed in the upper and lower hinge slots at the inner end of the adjustable cover plate 500, and are connected into one piece by the adjusting screw 501 to form an openable hinge structure.

[0043] Specifically, one end of the L-shaped mounting plate 300 is fixed to the inside of the UHPC mounting plate by expansion bolts 302, and the other end extends into the light trough to form a support platform. A cylindrical hinge 301 is welded to the other end of the L-shaped mounting plate 300, and its circular through-hole is coaxially aligned with the hinge slots at the upper and lower ends of the adjustable shield. The adjusting screw 501 passes sequentially through the upper hinge slot, the upper cylindrical hinge, the lower cylindrical hinge, and the lower hinge slot, forming a circumferential limit with the shield through a hexagonal shaft hole. When the adjusting screw 501 is rotated, the hexagonal cross-section and the hexagonal hole inside the shield generate torque transmission, causing the shield to rotate around the hinge axis to adjust the opening angle. For disassembly and maintenance, simply loosen the nuts at both ends to remove the screw, separating the L-shaped mounting plate 300 and the shield 500 from the L-shaped mounting plate 300.

[0044] In addition, such as Figure 2 As shown, this application further proposes that the other end of the L-shaped mounting plate 300 be fixedly mounted on the inner wall of the light trough plate 201 by an expansion bolt 302. The expansion bolt 302 refers to a mechanical fastener with an expansion sleeve, which can be made of metal. When its threaded shank is screwed into the pre-drilled hole, radial pressure is generated through the expansion of the sleeve, utilizing the high density of the UHPC material to form a mechanical engagement. This feature achieves a rigid connection through the frictional force generated by mechanical expansion, avoiding chemical bonding dependence on the concrete substrate.

[0045] In some of these embodiments, such as Figure 2 As shown, this application further proposes that the lighting unit 400 can be rotatably mounted on the adjusting bracket 401, and the adjusting bracket 401 is fixedly mounted on the L-shaped mounting plate 300 by screws 402. The rotatably mounted adjusting bracket 401 is used for the rotatable connection structure of the lighting unit 400, which can be implemented using a hinge mechanism with a rotating shaft. This structure allows the lighting unit to be angularly adjusted around a fixed axis.

[0046] Specifically, the lighting unit 400 is rotatably connected to the adjustment bracket 401 via rotating shafts at its top and bottom. When the light projection direction needs to be adjusted, the lighting unit 400 can be rotated manually or with the aid of tools to rotate around the rotating shaft to a predetermined angle. The adjustment bracket 401 is connected to the L-shaped mounting plate 300 via screws 402. Under the premise of ensuring structural stability, the bracket position can be adjusted or the lighting fixture can be replaced by removing the screws 402.

[0047] Furthermore, depending on the actual application requirements, the lighting unit 400 can use LED lights, wall washer lights, floodlights, or spotlights. Specifically, LED lights refer to lighting devices that use semiconductor light-emitting diodes as the light source; wall washer lights refer to linear lighting devices with a wide beam angle; floodlights refer to lighting devices that project strong light in a directional manner; and spotlights refer to small point light sources with adjustable illumination direction. LED lights are preferred. LED lights are fixed to the adjustment bracket via a standardized interface, operate continuously under stable voltage, and their low heat generation characteristics reduce the heat dissipation load in the UHPC enclosed space.

[0048] In some of these embodiments, such as Figure 3 As shown, this application further proposes that the adjustable baffle 500 is a vertically arranged plate structure with an internal hexagonal shaft hole through the upper and lower sides at its inner edge, and a hinge groove is provided at the upper and lower ends of the inner side respectively. The internal hexagonal shaft hole is limited to the insertion of an adjusting screw 501 with a hexagonal cross-section, and the upper and lower ends of the adjusting screw 501 are correspondingly inserted into the circular through holes of the cylindrical hinge 301 on the L-shaped mounting plate 300.

[0049] Specifically, when the adjusting screw 501 is rotated, its hexagonal cross-section creates surface contact friction with the inner wall of the internal hexagonal shaft hole, thereby causing the adjustable baffle plate 500 to rotate around the cylindrical hinge 301 within the hinge slot. Since the adjusting screw 501 passes through both the upper and lower ends of the cylindrical hinge 301, the upper and lower ends of the adjustable baffle plate 500 form a synchronously rotating linkage structure. The hexagonal cross-section design prevents relative sliding between the adjusting screw 501 and the shaft hole, ensuring that the rotation angle of the adjustable baffle plate 500 strictly corresponds to the rotation angle of the adjusting screw 501. The nested structure of the hinge slot and the cylindrical hinge 301 forms a stable rotational fulcrum, preventing axial displacement of the adjustable baffle plate 500 during adjustment.

[0050] Through the above technical solution, this application realizes the stepless physical adjustment function of the lamp brightness. During the adjustment process, the opening and closing angle of the adjustable baffle 500 and the rotation angle of the adjusting screw 501 maintain a strict correspondence, solving the problem of idle travel in traditional mechanical adjustment mechanisms. The fit structure between the hexagonal adjusting screw 501 and the shaft hole prevents slippage during the adjustment process, ensuring the positioning accuracy of the adjustable baffle 500.

[0051] In some of these embodiments, such as Figure 3As shown, this application further proposes that a metal sleeve 302 be rotatably fitted onto the upper and / or lower ends of the adjusting screw 301, and the metal sleeve 302 be correspondingly embedded in the through holes at the upper and lower ends of the light trough plate 201. The metal sleeve 302 is a hollow cylinder made of metal material, specifically stainless steel or aluminum alloy. This sleeve serves as a wear-resistant medium layer, bearing the frictional load when the adjusting screw 301 rotates, thus preventing the inner wall of the concrete through hole from directly contacting the screw.

[0052] In some of these embodiments, such as Figure 3 As shown, this application further proposes that an adjusting nut be provided at the top of the adjusting screw 301, which can be manually adjusted by rotating it with a wrench. The adjusting nut refers to a polygonal structure provided at the top of the adjusting screw, specifically a hexagonal nut. This structure is compatible with standard wrench tools and facilitates angle adjustment by manual rotation.

[0053] Alternatively, the adjusting nut can be automatically rotated and adjusted via an electric drive mechanism. The adjusting nut is a gear structure with a rack and pinion on its outer periphery, and its automatic rotation is achieved through an electric drive mechanism. This electric drive can be a servo motor, which drives the output wheel on the output shaft to mesh with the rack and pinion on the outer periphery of the nut, causing the adjusting screw 301 to rotate synchronously. This method provides a physical connection basis for remote control or automated adjustment.

[0054] Specifically, the adjusting nut is fixedly connected to the top of the adjusting screw 501. When it is necessary to adjust the opening angle of the adjustable baffle 500, a rotational force can be applied to the adjusting nut at the top of the adjusting screw 501 by manually using a wrench, causing the adjusting screw 301 to rotate around its axis, thereby driving the adjustable baffle 500 hinged to the screw to change its angle. If an electric drive mechanism is used, the motor output shaft is connected to the adjusting screw 501. By controlling the forward and reverse rotation of the motor, the adjusting screw 501 can be rotated clockwise or counterclockwise, thereby precisely controlling the opening angle of the adjustable baffle (500).

[0055] Combination Figures 1 to 5 As shown, the UHPC concrete-embedded lighting physical adjustment system provided in this application uses L-shaped mounting plates 300 respectively installed in the upper and lower ends of the lighting trough plate 201 at the front end of the UHPC exterior wall panel 200. A lighting unit 400 and an adjustable shielding plate 500 are vertically installed on the L-shaped mounting plate 300. Through the adjustable rotational cooperation structure between the L-shaped mounting plate 300 and the adjustable shielding plate 500, the light angle and illumination range of the lighting unit 400 are precisely controlled mechanically. This avoids the electrical interference of traditional voltage regulation on the lighting fixtures and achieves non-destructive maintenance. It has the advantages of extending the service life of the lighting fixtures and improving the adjustability of the lighting effect.

[0056] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
