Description

Technical Field

[0001] This invention relates to the field of LED wall washer technology, specifically to an LED structure high-efficiency heat dissipation wall washer. Background Technology

[0002] In the field of modern lighting technology, wall washer lights, widely used in architectural decorative lighting and for outlining the contours of large buildings, are highly favored for their ability to create unique lighting effects. Among them, strip wall washer lights play an important role in many scenarios due to their unique shape and linear light output characteristics. Currently, the mainstream design of strip wall washer lights typically involves installing LED lamp heads inside a strip-shaped housing.

[0003] In terms of heat dissipation, existing technologies have significant shortcomings. On the one hand, they mainly rely on the housing itself for heat dissipation. However, when wall washer lights are working, the LED lamp heads generate a lot of heat, and relying solely on the housing for heat dissipation is insufficient to quickly dissipate the heat, causing heat to gradually accumulate inside the housing. On the other hand, although there are methods to increase the heat dissipation area by creating heat dissipation grooves on both sides, the size, number, and distribution of these grooves limit the air convection effect within them, making it difficult to form an efficient heat dissipation channel and fully realize the intended effect of increasing the heat dissipation area. Overall, this heat dissipation structure cannot meet the heat dissipation requirements of LED lamp heads during long-term stable operation, resulting in excessively high internal temperatures in the lamp fixture. This severely affects the luminous efficiency and lifespan of the LED lamp heads and may also cause problems such as light decay and color drift, reducing lighting effects and the reliability of the lamp fixture. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide a high-efficiency heat dissipation wall washer light with an LED structure to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency heat dissipation wall washer light with LED structure, comprising a frame assembly and an LED light module, wherein the frame assembly consists of a base plate fixed to one side of the bottom of a fixed end plate and mounting beams fixed to the two top corners of the fixed end plate;

[0006] The inner end face of the fixed end plate has mating grooves on both sides, and the mating grooves are used to insert the vertical sealing plate near the fixed end plate. The top inner side of the fixed end plate has a snap-fit ​​groove, which is used to snap the multi-layer snap-fit ​​block that fixes the end of the transparent plate.

[0007] The frame assembly is connected in sequence from the inside to the outside to multiple sets of heat dissipation components composed of heat dissipation shells. The multiple sets of heat dissipation shells are connected to each other and sealed by vertical sealing plates and vertical sealing grooves. When multiple sets of heat dissipation components are connected in sequence, the vertical sealing plate and the vertical sealing groove of the adjacent heat dissipation component form a vertical sealing connection to prevent impurities from entering along the arrangement direction of the heat dissipation components.

[0008] Each heat dissipation shell has heat dissipation pipes fixed at both ends inside. The heat dissipation pipes have heat dissipation through holes that communicate with the outside. The heat dissipation through holes are used to form air convection channels to promote heat exchange between the inside and outside of the heat dissipation shell. Both sides of the heat dissipation shell are fixed with protruding heat dissipation boxes. The internal cavity of the heat dissipation box is connected to the internal cavity of the heat dissipation shell. The heat dissipation box increases the heat dissipation surface area and guides the airflow path to improve heat dissipation efficiency. Multiple heat dissipation components together form a continuous heat dissipation structure that extends along the length of the frame component.

[0009] The positioning insertion strips on both sides of the top of the heat dissipation shell extend into the transverse insertion slots inside the two sets of mounting beams, so as to limit the displacement of the heat dissipation components in the horizontal and vertical directions.

[0010] The bottom horizontal plug plate on the inner side of the bottom of the heat dissipation shell extends into the slot inside the base plate to enhance the connection strength between the heat dissipation component and the frame component and form a horizontal seal. The multiple heat dissipation components together form a continuous heat dissipation structure extending along the length of the frame component, and the vertical sealing plate between adjacent heat dissipation components and the cooperation between the bottom horizontal plug plate and the base plate together constitute a waterproof and dustproof structure.

[0011] The heat dissipation assembly also includes an inner support frame fixed inside the heat dissipation housing, and the inner support frame has a mounting slot for mounting LED lamp modules.

[0012] It also includes a light-transmitting component that works with the frame assembly. The light-transmitting component includes a transparent plate with waterproof insert strips extending into the interior of two sets of mounting beams fixed on both sides of the transparent plate. One end of the transparent plate is provided with a multi-layer locking block that engages with the frame assembly.

[0013] The LED light module includes a circuit board on which a lamp head module and an adapter are mounted. One end of the adapter is connected to a plug, and the other end is provided with a socket that mates with an adjacent LED light module.

[0014] It also includes an end plate assembly for sealing the end of the frame assembly, the end plate assembly including a movable end cap, the movable end cap having a circular hole corresponding to the plug, and the movable end cap being fixedly connected to the frame assembly by a fastening assembly.

[0015] By adopting the above technical solution, and through the modular splicing design of multiple heat dissipation components, a collaborative heat dissipation structure is formed by the heat dissipation shell, heat dissipation pipes, and heat dissipation boxes. The heat dissipation holes in the heat dissipation pipes create air convection channels to accelerate internal and external heat exchange. The protruding heat dissipation boxes on both sides significantly increase the heat dissipation surface area, and with the help of airflow guidance, the heat dissipation efficiency is improved. This effectively solves the problem of heat accumulation caused by traditional wall washer lights relying solely on shell heat dissipation, ensuring stable operating temperature of the LED light module, extending service life, and reducing light decay and color drift. At the same time, the heat dissipation components are vertically sealed by vertical sealing plates and vertical sealing grooves. The cooperation between the bottom horizontal plug plate and the base plate slot, and the positioning plug strip and the horizontal plug groove of the mounting beam enhance the connection strength and sealing performance. The multi-layer snap-fit ​​and waterproof plug strip design of the light-transmitting components further improves the overall protection performance, preventing impurities from entering and rainwater from seeping in, adapting to complex outdoor environments, and ensuring long-term stable operation of the lamps. In addition, the modular structure allows for flexible splicing of different lengths according to needs, making installation and maintenance convenient and improving applicability and practicality.

[0016] Furthermore, the two sets of mounting beams are provided with strip-shaped drainage holes extending along their extension direction, and the bottom surface of the strip-shaped drainage holes is inclined.

[0017] By adopting the above technical solution, the inclined bottom design utilizes gravity to allow water to naturally converge and accelerate discharge along the inclined direction, thereby improving drainage efficiency. It is especially suitable for long installation beams and avoids local water accumulation due to poor drainage.

[0018] Furthermore, both the fixed end plate and the movable end cover are provided with protective covers on their outer sides to protect the plug and socket.

[0019] By adopting the above technical solutions, the plug and socket are key components for equipment connection. Long-term exposure to the outside environment can easily lead to poor contact due to the intrusion of impurities such as dust, moisture, and oil, and may even cause short circuits or leakage. The protective cover forms a physical barrier, effectively blocking external contaminants, reducing component wear and corrosion, thereby extending the service life of the plug, socket, and the entire equipment.

[0020] In summary, the present invention has the following main advantages: Through a modular splicing design of multiple heat dissipation components, the present invention utilizes a heat dissipation shell, heat dissipation pipes, and heat dissipation boxes to form a collaborative heat dissipation structure. The heat dissipation through-holes within the heat dissipation pipes create air convection channels, accelerating internal and external heat exchange. The protruding heat dissipation boxes on both sides significantly increase the heat dissipation surface area, and combined with airflow guidance, improve heat dissipation efficiency. This effectively solves the problem of heat accumulation caused by traditional wall washer lights relying solely on shell heat dissipation, ensuring stable operating temperature of the LED light module, extending its service life, and reducing light decay and color drift. Simultaneously, the heat dissipation components form a vertical seal through vertical sealing plates and grooves. The cooperation between the bottom horizontal insertion plate and the base plate slot, and the positioning insertion strip and the horizontal insertion groove of the mounting beam, enhances connection strength and sealing. The multi-layer snap-fit ​​design of the light-transmitting components and the waterproof insertion strip design further improve overall protection performance, preventing impurities from intruding and rainwater from leaking, adapting to complex outdoor environments, and ensuring long-term stable operation of the lamp. Furthermore, the modular structure allows for flexible splicing of different lengths according to needs, facilitating installation and maintenance, and improving applicability and practicality.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of the present invention will now be described.

[0035] Example 1

Inside, there are transverse insertion grooves 107 and strip-shaped drainage holes 106 for the positioning insertion strips 202 adapted to the heat dissipation component 2. The bottom surface is inclined with a slope of 5° for drainage.

[0041] The heat dissipation component 2 adopts a multi-modal design, spliced ​​along the length of the frame component 1, with each component being 30cm long;

[0042] This includes the heat sink 201:

[0043] The heat dissipation shell 201 is made of one-piece aluminum alloy shell. The top two sides are provided with positioning plug strips 202 that are inserted into the mounting beam 103, and the bottom inner side is provided with a bottom horizontal plug plate 203 that is inserted into the horizontal plug groove 107 to enhance the connection strength and overall waterproof performance.

[0044] The high-efficiency heat dissipation structure includes:

[0045] The heat dissipation pipe 204 consists of two sets of metal pipes, which are fixed at both ends inside the heat dissipation shell 201. A heat dissipation through hole 205 is opened axially to communicate with the external space, forming an air convection channel.

[0046] The heat sink 206 is a hollow box with protruding sides, which is connected to the interior of the heat sink shell 201. By increasing the surface area, it guides airflow and accelerates heat exchange.

[0047] Sealing and connection: The heat dissipation housing 201 is provided with vertical sealing plates 209 and vertical sealing grooves 210 at the beginning and end respectively. After adjacent components are inserted, a vertical seal is formed. The inner support frame 207 is fixed on the inner side, and an installation groove 208 is opened on it for fixing the LED lamp module 3.

[0048] LED light module 3:

[0049] The circuit board 301 is installed in the mounting slot 208 of the inner support frame, and the lamp head module 302 is soldered on the surface with a spacing of 10mm and the color temperature is adjustable from 3000K to 6500K.

[0054] End plate assembly 5: The movable end cover 501 is fixed to the other end of the frame assembly 1 by the fastening assembly 503, and a round hole 502 is opened for the plug 304 to pass through, which cooperates with the vertical sealing groove 210 at the end of the heat dissipation assembly 2 to form an end seal.

[0055] The protective cover 6 is a plastic cover that is fastened to the outside of the fixed end plate 102 and the movable end cover 501 respectively, protecting the plug 304 and the socket 304 from dust and rainwater corrosion.

[0056] Component assembly

[0057] Heat dissipation component 2 splicing: Multiple heat dissipation components 2 are inserted sequentially along the length of frame component 1. The vertical sealing plate 209 of the first group is inserted into the mating groove 104 of the fixed end plate 102. Subsequent components are connected to the vertical sealing groove 210 through the vertical sealing plate 209 to form a continuous sealing structure.

[0058] LED module 3 installation: The circuit board 301 of the LED module 3 is embedded into the mounting slot 208 of the heat dissipation component 2, and adjacent modules are connected to the socket 305 through the plug 304 to form a complete circuit.

[0059] Fixing the light-transmitting component 4: Insert the waterproof connector strip 402 of the transparent plate 401 into the mounting beam 103, and the multi-layer snap-fit ​​block 403 snaps into the snap-fit ​​groove 105 of the fixed end plate 102 to complete the front sealing;

[0060] End processing and debugging

[0062] Functional test: When the power is turned on, the LED lamp head module 302 lights up. Check the uniformity of light transmission. Simulate a rainy environment to verify the waterproof performance of the sealed structure. If there is no water leakage after 30 minutes, it is considered successful.

[0063] Heat dissipation and operation

[0064] Heat dissipation path: The heat generated by the LED module 3 during operation is transferred to the heat dissipation housing 201, and the heat dissipation area is increased through the heat dissipation box 206. At the same time, the heat dissipation holes 205 of the heat dissipation pipe 204 form air convection, which quickly dissipates the heat to the outside.

[0065] Drainage design: A small amount of rainwater that seeps into the mounting beam 103 is discharged at an angle through the strip-shaped drainage hole 106 to avoid water accumulation affecting the circuit;

[0066] Finally, a mounting bracket assembly is fixedly installed at the bottom of the base plate 101. The mounting bracket assembly is used to install the wall washer light on the ground or the exterior of the building, so that the light generated by the LED light module 3 can achieve a bright wall washer effect on the exterior of the building.

[0067] In summary, the combination of the convection channel of the heat pipe 204 and the increased surface area design of the heat sink 206 improves the heat dissipation efficiency by 50% compared with the traditional structure, and reduces the operating temperature of the lamp to below 60℃.

[0068] The multi-layer snap-fit ​​block 403, the vertical sealing plate 209 and the waterproof plug strip 402 form a three-dimensional sealing structure with a protection level of IP65, which is suitable for outdoor rainy and dusty environments. The heat dissipation component 2 and the LED light module 3 can be flexibly spliced ​​to adapt to different length requirements, making installation and maintenance convenient and reducing replacement costs.

[0069] Optimized heat dissipation avoids light decay and color drift caused by high temperature in the lamp head module 302, and improves light uniformity by 20%, ensuring stable and long-lasting wall washing effect;

[0070] This embodiment is applicable to outdoor lighting scenarios such as building exterior walls and bridges. Through efficient heat dissipation and reliable sealing, it ensures the long-term stable operation of the luminaire in complex environments.
