Description

Technical Field

[0001] This utility model relates to the field of lighting fixture technology, specifically to a decorative lamp with a flame visual effect and a structured installation assembly. Background Technology

[0002] Flame effect lighting fixtures are decorative lighting devices that combine optics, structural design, and electronic control. They simulate the visual dynamics of flames through specific optical structures and light source layouts, and are widely used in commercial displays, atmosphere creation, and architectural decoration. These fixtures typically include a light source module, optical diffusion components, an exterior decorative structure, and electrical control components. Their core lies in achieving a realistic flame visual effect through structural design, while also ensuring ease of installation, structural stability, and environmental adaptability.

[0003] Currently, most flame effect lighting fixtures on the market use simple light-transmitting holes or diffusers combined with LED light sources to achieve basic light and shadow simulation. However, they still have shortcomings in terms of structural integration, installation stability, and the realism of visual effects. For example, some fixtures have a simple decorative mesh structure, a lack of layering in the layout of the light-transmitting holes, and a harsh flame effect. The installation structure often uses ordinary flat mounting plates, which are difficult to adapt to various installation environments and are prone to displacement or loosening during installation. The sealing between the optical diffuser and the lamp body is insufficient, affecting the protection level and lifespan of the fixture. In addition, existing fixtures have a relatively loose electrical layout, making driver installation inconvenient and hindering the overall structural compactness and ease of maintenance.

[0004] While existing flame lamps possess basic visual effects and lighting functions, there is still room for improvement in terms of structural integration, installation reliability, and optical performance. Specifically: 1. Decorative mesh structures are mostly flat or simple curved surfaces, with evenly distributed light-transmitting holes but lacking a three-dimensional feel and dynamic simulation effect; 2. The installation structure is simple, but it does not take into account the installation stability and ease of adjustment in complex environments; 3. The sealing structure between the optical components and the lamp body is imperfect, affecting the protective performance; 4. The loose layout of electrical components is not conducive to the optimization and maintenance of the overall structure.

[0005] Based on the above analysis, it is necessary to provide a flame effect decorative lamp with a more reasonable structure, more stable installation, more realistic flame effect, and good protective performance to solve the above-mentioned problems in the existing technology. Summary of the Invention

[0006] This utility model aims to overcome the aforementioned defects of existing flame effect lighting fixtures and provide a decorative lighting fixture with a reasonable structural design, stable and reliable installation, realistic flame simulation effect, and good environmental adaptability. Specifically, the purpose of this utility model is: 1. Enhance visual effects: By optimizing the structure of the decorative mesh and the layout of the light-transmitting holes, a more natural, three-dimensional, and dynamic flame light and shadow simulation effect is achieved, overcoming the problems of stiff effects and insufficient sense of layering in existing technologies.

[0007] 2. Enhanced structural stability: Provides a highly integrated, easy-to-install, and securely fixed back-mounting structure to ensure that the luminaire remains stable in various installation environments and avoids loosening or shifting.

[0008] 3. Improved protection performance: Optimized sealing method between optical components and main structure, effectively improves the dustproof and waterproof rating of lamps, extends their service life and expands their application scenarios.

[0009] 4. Optimize internal layout: Rationally plan the installation location and space of electrical components to make the overall structure more compact, which facilitates production assembly and subsequent maintenance.

[0010] To achieve the above-mentioned objectives, the present invention adopts the following technical solution: A flame-effect decorative light fixture includes: a mounting box; a first end cap and a second end cap, respectively disposed at both ends of the mounting box along its length; a decorative mesh disposed between the first end cap and the second end cap and connected to the mounting box; and an optical component disposed on the mounting box and located inside the decorative mesh.

[0011] Furthermore, the decorative mesh has a semi-cylindrical curved surface structure with multiple through holes evenly distributed in an array.

[0012] Furthermore, a groove is formed on the back side of the mounting box, and a mounting plate is disposed in the groove. The mounting plate is fixed to the side wall of the mounting box by fasteners.

[0013] Furthermore, a drive cover plate is also provided in the groove. The drive cover plate is fixed to the mounting box by fasteners and covers a part of the groove. The drive cover plate and the mounting box enclose a cavity for accommodating the driver.

[0014] Furthermore, the optical component includes a diffuser and an aluminum substrate disposed on the back side of the diffuser, the diffuser being fixed to the mounting box by fasteners.

[0015] Furthermore, a sealing gasket is provided between the diffuser cover and the mounting box, and the edge of the diffuser cover is formed with a groove for accommodating the sealing gasket.

[0016] Furthermore, the mounting plate is octagonal in shape.

[0017] Furthermore, the through holes on the decorative mesh are small holes, and are arranged in a rectangular array along the curved surface of the decorative mesh.

[0018] Furthermore, the driver is a smart WIFI LCB driver, and the lamp also includes an LED light source disposed on the aluminum substrate, the LED light source being electrically connected to the driver.

[0019] Furthermore, the overall dimensions of the lamp are 350mm in length × 130mm in width × 80mm in height, the rated power of the driver is 15W, and the protection level of the lamp is IP54.

[0020] Compared with the prior art, the present invention has the following significant advantages: 1. Significantly improved realism of flame effects: The decorative mesh with a semi-cylindrical curved surface, combined with the light-transmitting holes arranged in an array on its surface, allows light to be transmitted from different angles and with different intensities, forming a three-dimensional light and shadow with interplay of light and shadow, a sense of depth and dynamic changes, which greatly simulates the visual effect of real flames flickering.

[0021] 2. Enhanced installation stability and adaptability: By setting a dedicated mounting plate (especially the octagonal structure) in the groove on the back of the mounting box, a larger and more reasonable stress area and multi-point fixing support are provided, making the lamp installation more secure, effectively resisting vibration and external forces, and adapting to diverse installation base requirements.

[0022] 3. Improved structural sealing and protection level: A sealing gasket is installed between the diffuser and the mounting box, achieving effective sealing of the optical cavity. Combined with the enclosed design of the electrical cavity by the drive cover, this constitutes double protection, enabling the luminaire to easily achieve an IP54 or higher protection level, suitable for complex environments such as outdoor and semi-outdoor spaces.

[0023] 4. Optimized internal layout for convenient maintenance: Electrical components such as drivers and power supplies are centrally located in an independent chamber within a recessed area on the back side, and encapsulated by a removable driver cover, achieving separation between the electrical and optical areas. This modular layout not only makes the structure compact and the heat dissipation path clear, but also greatly facilitates daily maintenance and component replacement.

[0024] 5. Balancing Aesthetics and Practicality: The unique curved decorative mesh and compact back design provide excellent functionality while ensuring the lamp's aesthetic appeal and avoiding a bulky appearance. The integration of intelligent control functions further enhances the product's added value and user experience. Attached Figure Description

[0027] The technical solution of this utility model will be described in detail and completely below with reference to the accompanying drawings, so that any person skilled in the art can fully understand and reproduce this utility model. The described embodiments are some embodiments of this utility model, but not all embodiments.

[0028] This utility model provides a flame-effect decorative lighting fixture, particularly suitable for creating a flame-themed atmosphere for indoor and outdoor walls, courtyards, commercial spaces, and other locations. Please refer to [link / reference]. Figures 1 to 4 The lamp mainly includes a mounting box 1 as the main support structure, a first end cover 2 and a second end cover 3 respectively sealed at both ends of the mounting box 1 along its length, a decorative mesh 4 that constitutes the main visual appearance, an optical component for light control, and a mounting and electrical module integrated on the back side of the mounting box 1.

[0029] The mounting box 1, serving as the core framework of the entire lighting fixture, is typically made of sheet metal (such as aluminum alloy) through stamping and bending, providing excellent structural strength and heat dissipation. Its main body is a groove-shaped structure with an open front and a closed rear. On the back side of the mounting box 1, facing the mounting wall, a regular recess is formed. This recess design not only reduces the overall weight but, more importantly, provides dedicated space for the installation and wiring of internal electrical components.

[0030] The first end cap 2 and the second end cap 3 are preferably made of the same metal or high-strength engineering plastic as the mounting box 1, and are tightly fixed to the openings at both ends of the mounting box 1 by multiple countersunk screws or snap-fit ​​structures. Their main function is to seal the internal cavity of the mounting box 1, preventing dust and moisture from entering from both ends, and together with the mounting box 1, form a complete and robust shell, providing protection for all internal components. The outer surface of the end caps can be smoothed or decoratively treated to maintain consistency with the overall style.

[0031] Decorative mesh 4 is a key external component for creating the visual effect of flames. It is made of thin metal sheets (such as stainless steel or galvanized steel) through processes like punching and rolling, resulting in a standard semi-cylindrical curved surface. The curvature of this surface is optimized through optical simulation to conform to the internal light distribution. Thousands of tiny through-holes (or light-transmitting holes) are evenly distributed with extremely high precision across the entire curved surface of decorative mesh 4. These through-holes are typically arranged in a rectangular array aligned horizontally and vertically, with the hole diameter and spacing designed according to the desired light spot size and density. The two long sides of decorative mesh 4 are securely mounted to the edge of the front opening of mounting box 1 using screws via continuous folded edges or welded fixing pieces, thus forming a continuous and aesthetically pleasing curved outer surface between the first end cap 2 and the second end cap 3.

[0032] Optical components are the core of light generation and directly determine the quality of emitted light. For example... Figure 3 and Figure 4 As shown, the component mainly includes a diffuser 8 and an aluminum substrate 9. The main body of the diffuser 8 is injection molded from PMMA (acrylic) or PC material with high light transmittance and high diffuser properties. Its shape is designed to conform to the inner curved surface of the decorative mesh 4 to ensure that the light can uniformly cover the entire decorative mesh area. The edge of the diffuser 8 extends outward with a flange edge 81, which has multiple mounting holes 82. During installation, a sealing gasket made of sealing rubber or silicone is placed in the pre-set annular groove 83 on the back of the diffuser 8 flange, and then the entire diffuser 8 is tightly locked to the inside of the front opening of the mounting box 1 by bolts passing through the mounting holes 82. This sealing structure is crucial, as it ensures the isolation of the internal optical cavity of the lamp from the external environment and is one of the keys to achieving the IP54 protection rating. On the back side of the diffuser 8 (i.e., the side facing the inside of the mounting box 1), a long strip of aluminum substrate 9 is fixed by thermally conductive adhesive or mechanical clips. The aluminum substrate 9 not only serves as a circuit carrier but also as an important heat dissipation component. Its surface is covered with multiple high-efficiency, high color rendering index (Ra≥90) LED chips. These chips can be single-color temperature, dual-color temperature (CCT), or RGBW full-color models, depending on the product specifications. The direction and density of the LED chip arrangement correspond to the through-hole array on the decorative mesh 4, together forming the basis of the flame light effect.

[0033] The installation and electrical integration system for the lighting fixtures is mainly located in the recessed area on the back side of mounting box 1, such as... Figure 2As shown, a mounting plate 5 is provided in the center of the recess. This mounting plate 5 has multiple universal mounting holes 51 and / or mounting grooves 52. The mounting plate 5 can be directly fastened to the groove wall at the bottom of the mounting box 1 using two or more high-strength bolts passing through its surrounding mounting holes, forming an extremely stable mounting base. During installation, expansion bolts can be driven into the wall at corresponding positions, and then the mounting plate 5 of the entire lamp can be aligned and fixed, thus achieving a reliable connection between the lamp and the wall.

[0034] On both sides of the mounting plate 5, drive cover plates 6 are also provided in the grooves. The drive cover plates 6 are usually stamped from metal plates, and their shape matches the local contour of the groove. They are also fixed to the mounting box 1 by bolts, covering most of the space in the groove except for the area occupied by the mounting plate 5. The drive cover plates 6 and the groove wall of the mounting box 1 together form a relatively independent electrical chamber. In this electrical chamber, the "brain" of this lamp - the driver 7 - is installed. The driver 7 in this embodiment is a 15W rated power smart WIFI LCB driver, which supports wide voltage input (120-277V AC), has high power factor (PF≥0.9), low harmonic distortion (THD≤20%) characteristics, and integrates a 0-10V dimming signal interface. The driver 7 is connected to the LED light source on the aluminum substrate 9 through wires, providing it with a stable and controllable drive current. Users can remotely control the lamp's switch, brightness, color temperature (for CCT or RGBW models), and even dynamic scene modes via WIFI through a mobile APP or smart home system. The presence of the drive cover 6 not only protects the internal electrical components from external damage and environmental influences, but also makes the back of the lamp look neat and beautiful, and facilitates disassembly when maintenance is required.

[0035] During assembly, the LED light source is first soldered onto the aluminum substrate 9 and tested. Then, the aluminum substrate 9 is fixed to the back of the diffuser 8. Next, a sealing gasket is placed into the groove of the diffuser 8, and the diffuser 8 with the aluminum substrate 9 is fitted into the mounting box 1 from the front of the lamp and tightened with bolts to complete the sealed assembly of the optical cavity. Subsequently, the mounting plate 5 and the driver 7 are installed and fixed in sequence in the groove on the back of the mounting box 1, and finally the driver cover plate 6 is covered and locked. The decorative mesh 4 is covered and fixed to the front of the mounting box 1, and finally the first end cover 2 and the second end cover 3 are installed to complete the assembly of the entire lamp.

[0036] In summary, this invention achieves a vivid, realistic, and three-dimensional simulation of flame light and shadow through the innovative combination of a semi-cylindrical curved decorative mesh and a precision through-hole array, along with an internal arc-shaped diffuser and high color rendering LEDs. Its unique octagonal mounting plate on the back and robust bolt fixing method provide superior installation stability and adaptability. The double-sealed design of the optical components and electrical chamber ensures long-term reliable operation of the luminaire in complex outdoor environments. The modular structural layout makes production, assembly, and maintenance more convenient and efficient. Therefore, this invention successfully provides a flame effect decorative lighting solution with excellent visual effects, stable and reliable structure, and strong environmental adaptability.
