Description

Technical Field

[0001] This application relates to the field of lighting technology, specifically to the field of energy-saving linear lighting devices based on industrial aluminum alloy profile channels. Background Technology

[0002] In industrial settings, such as warehouse shelves, assembly line workbenches, and equipment racks, there is a widespread need for auxiliary lighting to provide status or path indications. The traditional approach is to install individual light fixtures or LED light strips.

[0003] However, this approach has potential drawbacks in practical applications. First, if the lighting fixtures are not properly cooled, prolonged operation can lead to localized temperature increases and energy waste. Second, the additional wiring introduces more connection points and weaker insulation, significantly increasing the probability of aging wiring and short circuits under dusty, high-temperature, or vibrating conditions, thus becoming a potential cause of fires.

[0004] To address these issues, some sites have opted to replace conventional warning or auxiliary lighting with explosion-proof lights. However, explosion-proof lights are significantly more expensive to purchase, and their bulky structure not only occupies extra space but also requires specialized maintenance, resulting in low overall cost-effectiveness and a clear overpayment.

[0005] To address the aforementioned contradictions, there is an urgent need for an integrated lighting solution that can both utilize existing industrial structures to achieve efficient heat dissipation and simplify installation while avoiding additional wiring. Summary of the Invention

[0006] This application proposes an energy-saving linear lighting device based on the channel of an industrial aluminum alloy profile, so as to achieve rapid installation, reliable bonding and efficient heat dissipation of LED light strips in the industrial aluminum alloy profile.

[0007] To achieve the above objectives, the present application adopts the following technical solution: This application proposes an energy-saving linear lighting device based on an industrial aluminum alloy profile channel, wherein the industrial aluminum alloy profile has a channel extending along its length direction, the channel being formed by the gap between an outer peripheral beam and an inner core. The energy-saving linear lighting device includes: An LED light strip that can be inserted along the channel direction, wherein the LED light strip is provided with spaced LED beads; Multiple support pads are disposed between the LED beads, and the support pads are elastic elements used to support the LED light strip; And a lampshade that is inserted into the groove from the outside of the outer peripheral beam, wherein the lampshade is constructed to squeeze the support pad during the insertion process, so that the LED light strip is pressed tightly against the core.

[0008] In this way, the support pad is squeezed when the lamp cover is inserted, causing it to deform elastically. This automatically generates clamping force during installation, ensuring that the LED strip fits tightly against the core. This achieves a quick-installation and easy-to-disassemble integration method with good thermal contact, thereby improving installation reliability and heat dissipation efficiency.

[0009] In some possible implementations, end caps located at both ends of the channel are also included, the end caps having electrical holes for leading out power lines.

[0010] In some possible implementations, the support pad includes: The fixing part pre-bonded to the LED light strip; The elastic arms extend from the fixed part to both sides of the channel. The elastic arms are inclined toward the side of the channel and are located below the channel opening, so as not to block the opening area of ​​the channel.

[0011] In some possible implementations, the height of the pre-bonded support pad and LED strip is less than the height of the channel.

[0012] In some possible implementations, the lampshade includes an end cap portion extending from the outside to the inside and held by an outer peripheral beam, and a snap-fit ​​portion located inside the outer peripheral beam in the installed state.

[0013] In some possible implementations, the lampshade further includes a clamping portion that extends inward from the snap-fit ​​portion and abuts against the fixing portion.

[0014] In some possible implementations, the lampshade further includes a compression portion disposed between the snap-fit ​​portion and the pressing portion for compressing the elastic arm.

[0015] In some possible implementations, the support pad is made of nylon + 30% glass fiber or PBT + 30% glass fiber, and the lampshade is made of flame-retardant PC.

[0016] In some possible implementations, the lateral width w of the support pad is smaller than the opening width of the channel.

[0017] In some possible implementations, the angled distance L of the support pad is less than the spacing d between the LED beads. Attached Figure Description

Detailed Implementation

[0019] The following examples further illustrate the features of this application and other related features in detail, to facilitate understanding by those skilled in the art: It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions in the attached diagrams, while the terms “bottom surface,” “top surface,” “inner,” and “outer” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0020] Furthermore, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this case based on the specific circumstances.

[0021] In industrial automation and warehousing logistics scenarios, standardized industrial aluminum alloy profiles with channels (such as the 4040 and 5050 series) are widely used as equipment frames or support structures. This type of profile itself has a continuous, open channel system, which is used not only for mechanical connections but also provides a physical interface for functional integration.

[0022] Currently, LED linear light sources (such as aluminum-based flexible light strips) are widely used in auxiliary lighting or status indicators, featuring low power consumption, long lifespan, and high luminous efficacy. Especially when used for non-primary lighting applications, their LED chip density is typically low, allowing for passive heat dissipation entirely through the highly thermally conductive aluminum alloy profile. During operation, simply ensuring effective thermal contact between the LED aluminum substrate and the bottom of the channel is sufficient to rapidly conduct heat to the entire profile structure and dissipate it into the environment, eliminating the need for an additional heat sink.

[0023] However, while traditional adhesive methods (such as silicone glue or double-sided tape) can achieve a proper fit when fixing the LED strip to the groove, they have significant drawbacks. If the LED strip is damaged or requires cleaning or maintenance, the removal process easily leaves adhesive residue, damages the profile surface, and cannot be quickly repositioned, making it inconvenient for industrial applications. Furthermore, completely exposed LED strips lack necessary dust and electrical protection.

[0024] This is the installation solution that this application aims to solve, which allows for quick assembly and disassembly while ensuring good thermal contact and adequate sealing.

[0025] Please refer to Figure 1 and Figure 3 First, the aluminum alloy profile used in this embodiment will be described. This embodiment is based on a standardized aluminum alloy profile 100 widely used in the industrial field. This aluminum alloy profile 100 is usually made of high-strength aluminum alloy (such as 6063-T5) and is commonly used in equipment frames, workbenches, warehousing systems, and other scenarios. It is usually connected by corner brackets 200. The entire connection process uses standard connectors and is a common technical method in the industry. The connection method of this aluminum alloy profile 100 will not be described in detail.

[0026] Its cross-sectional structure includes a channel 110 extending along its length, naturally formed by the gap between the outer peripheral beam 120 and the inner core 130, providing a universal interface for accessory installation. The core 130 serves as a longitudinal support rib within the profile, typically featuring a positioning notch 131 on its outer periphery for positioning and auxiliary limiting with sliders or connectors. The outer peripheral beam 120 forms the outer contour of the profile and has a stepped portion 121 near the channel opening to provide an assembly reference surface or limit insertion depth. This structure is a standard design for industrial aluminum alloy profiles, supporting modular assembly without additional processing.

[0027] Therefore, based on the standardized structure of the built-in channel 110, this invention allows the LED light strip 10 to be directly embedded into the channel 110 without altering the profile itself. The metal enclosure space formed by the core 130 and the outer peripheral beam 120 achieves both bonding and efficient heat conduction. In other words, inserting the LED light strip 10 into the channel 110, ensuring it fits snugly against the core 130, and installing a light-transmitting cover between the outer peripheral beams 120—that is, at the opening of the channel 110—allows for the realization of a linear lighting device under existing structural conditions.

[0028] Please refer to the following for details. Figure 4 and Figure 8This application discloses an energy-saving linear lighting device based on an industrial aluminum alloy profile channel, comprising an LED light strip 10 that can be inserted axially along the channel 110. The LED light strip 10 uses an aluminum-based flexible circuit board, on which LED beads 11 are arranged at intervals, with a spacing d that can be a large distance of 15mm or more, suitable for low-density auxiliary lighting scenarios. To avoid the inconvenience of maintenance and installation caused by traditional adhesive fixing of the light strip, this device sets multiple support pads 30 between the LED beads 11. The support pads 30 can be pre-bonded to the LED light strip 10 at intervals. After the support pads 30 are installed, their overall height after pre-bonding with the LED light strip 10 is less than the height of the channel 110, ensuring that they can still be embedded inside the channel 110 after pre-bonding with the LED light strip 10, and are operable.

[0029] Furthermore, the support pad 30 includes a fixing part 31 pre-bonded to the LED light strip 10, and elastic arms 32 extending from the fixing part 31 to both sides of the channel 110. The elastic arms 32 are inclined toward the side wall of the channel 110, and their entire length is located below the opening of the channel 110, without obstructing the opening area of ​​the channel 110, thereby ensuring that the subsequent lamp cover 20 can be smoothly inserted without interference.

[0030] Please refer to the following: Figure 8 The lateral width w of the support pad 30 is less than the opening width of the channel 110, and its oblique angle distance L (i.e., the straight-line distance between the farthest ends of the fixing part 31) is designed to be less than the spacing d between the LED beads 11. This allows each support pad 30 to be easily replaced in a single LED bead area, and during subsequent maintenance and disassembly, the support pads 30 can be adjusted, replaced, or replenished without damaging the LED beads 11.

[0031] Further, please refer to Figures 5 to 7 After the initial positioning of the light strip 10 is completed, the lamp cover 20 is inserted into the groove 110 from the outside of the outer peripheral beam 120. The lamp cover 20 is injection molded from flame-retardant PC material, which has high light transmittance and flame retardancy, meeting industrial safety requirements. It also has good elastic deformation ability and automatic reset characteristics after unloading.

[0032] Specifically, the lampshade 20 includes an end cap 21 extending from the outside to the inside and held by the outer peripheral beam 120, and has a stepped structure design corresponding to the stepped portion 121 to provide lateral positioning and preliminary anti-detachment function. Furthermore, it also includes a latching portion 23 located inside the outer peripheral beam 120 in the installed state, for mechanically locking the outer peripheral beam 120 from inside the channel 110.

[0033] Based on this, a pressing part 22 extends inward from the buckle part 23 and abuts against the fixing part 31. The pressing part 22 is used to transmit the pressing force, so that the LED light strip 10 fits the core 130 more closely. At this time, the positioning notch 131 of the core 130 plays a limiting role when the LED light strip 10 is attached, so that as the lamp cover 20 is gradually inserted into the groove 110, the LED light strip 10 can be pressed and stably attached to the bottom surface of the core 130, avoiding slippage.

[0034] Furthermore, the lampshade 20 also includes a pressing part 24 disposed between the snap-fit ​​part 23 and the pressing part 22, for pressing the elastic arm 32. When the lampshade 20 is pressed in, the snap-fit ​​part 23 and the end cap part 21 clamp the outer peripheral beam 120. At the same time, the pressing part 24 contacts the elastic arm 32 and causes it to undergo controllable elastic deformation, while the pressing part 22 abuts against the fixing part 31, uniformly transmitting the entire pressing force to the bottom of the LED light strip 10, forcing it to fit tightly against the core 130. During this process, the elastic arm 32 can also move closer to both sides of the channel 110, further radially limiting the LED light strip 10, so that the LED light strip 10 can maintain a stable illumination angle.

[0035] Preferably, the support pad 30 is made of 70% nylon + 30% glass fiber or 70% PBT (polybutylene terephthalate) + 30% glass fiber, which has excellent temperature resistance (≥120°C). This gives it creep resistance and insulation properties, allowing it to maintain stable clamping force under long-term thermal cycling, continuously maintain heat dissipation efficiency, achieve energy saving, and extend LED lifespan.

[0036] Further, please refer to Figure 2 Both ends of the channel 110 are equipped with end caps 40, which have electrical holes 41 for leading out power lines. In this way, the ends of the channel are sealed off while the orderly introduction of power lines is achieved, simplifying on-site wiring and making it suitable for complex working conditions such as warehousing and assembly lines.

[0037] In summary, this embodiment achieves elastic deformation of the support pad 30 and the lampshade 20 by synergistically combining the support pad 30 and the lampshade 20, while preserving the original structure of the industrial aluminum profile 100. This automatically generates a clamping force during the installation of the lampshade 20, ensuring that the LED light strip 10 fits tightly against the core 130. This results in a quick-installation and disassembly with good thermal contact, thereby improving installation reliability and heat dissipation efficiency.

[0038] As stated above, this case protects energy-saving linear lighting devices based on industrial aluminum alloy profile channels, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
