Description

Technical Field

[0001] This utility model relates to a lamp panel and lamp fixture, and relates to the field of lamp fixture components and lamp fixture technology. Background Technology

[0002] With the continuous development of industrial production, LED lighting fixtures have been widely used in various industrial operating environments due to their advantages such as high efficiency, energy saving, and long lifespan. However, in extreme high-temperature, high-humidity, and corrosive industrial environments, the lifespan and reliability of traditional LED lighting fixtures face severe challenges.

[0003] For example, in some high-temperature workshops, the ambient temperature may reach 100 degrees Celsius. LED light panels operating under such high temperatures for extended periods are prone to damage from overheating of their internal electronic components and wiring. Simultaneously, high humidity environments can cause condensation on the light panel surface, leading to short circuits or corrosion. Furthermore, in environments with corrosive gases or liquids, the metal parts and electronic components of the light panel will also suffer severe corrosion, accelerating their aging and damage process.

[0004] In practical applications, traditional LED lighting fixtures often struggle to operate stably for extended periods in such harsh environments. For example, in a factory workshop, LED light panels operating at 100 degrees Celsius, even with continuous 24-hour operation, typically require replacement after two to three months. This frequent replacement not only increases operating costs but also leads to frequent downtime and maintenance during production, severely impacting production efficiency.

[0005] Therefore, improving the lifespan and reliability of LED lighting fixtures in extreme environments has become an urgent technical problem to be solved. Utility Model Content

[0006] This utility model provides a lamp panel and lamp fixture, aiming to solve at least one of the technical problems existing in the prior art.

[0007] The technical solution of this utility model is a light panel, which includes: a long strip-shaped LED light panel, wherein at least one row of LED beads is arranged on one side of the LED light panel along the extension direction, and an EVA adhesive layer covers the LED light panel and the LED beads. The edge of the EVA adhesive layer on each LED bead extends in an arc shape from the top of the LED bead to the side edge of the LED light panel on one side to form an LED light-transmitting surface for scattering light outward.

[0008] Furthermore, the LED light board is made of an aluminum substrate, and a solder resist layer is coated on the surface of the LED light board corresponding to the EVA adhesive layer.

[0009] Furthermore, a supporting housing is snapped onto the periphery of the LED light panel, and a power supply terminal is provided at one end of the LED light panel, with a wiring terminal connected to the terminal via a wire.

[0010] A lighting fixture includes: an elongated light-transmitting housing, a mounting housing sealed to the light-transmitting housing, a mounting groove provided on the inner wall of the mounting housing corresponding to the light-transmitting housing, and a lamp plate disposed in the mounting groove.

[0011] Furthermore, a sealing strip is pressed at the connection between the mounting housing and the light-transmitting housing, and the outer walls of the mounting housing and the light-transmitting housing are connected by multiple snap-fit ​​components.

[0012] Furthermore, the buckle assembly includes a slot and an elastic buckle that engages with the slot. The slot is disposed on the outer wall of the mounting housing or the light-transmitting housing, and the elastic buckle is correspondingly disposed on the outer wall of the light-transmitting housing or the mounting housing.

[0013] Furthermore, the mounting housing has a first end cap integrally formed at both ends, and the light-transmitting housing has a second end cap integrally formed at both ends.

[0014] A lamp includes: an elongated light-transmitting housing, a mounting housing sealed to the light-transmitting housing by adhesive, a mounting groove provided on the inner wall of the mounting housing corresponding to the light-transmitting housing, and a lamp plate disposed in the mounting groove.

[0015] Furthermore, the side of the light-transmitting housing corresponding to the lamp panel is an outwardly convex arc surface.

[0016] According to some embodiments of this utility model

[0017] The beneficial effects of this utility model include:

[0018] The LED panel and LED chips are covered with an EVA adhesive layer. This adhesive layer has excellent high-temperature resistance and can remain stable under high-temperature conditions, preventing damage to the chips and panel due to high temperatures, thereby extending the lifespan of the lamp in high-temperature environments. In addition, the edge of the EVA adhesive layer on each LED chip is arc-shaped, forming an LED light-transmitting surface for outward light scattering when adjacent LED chips are on the side of the LED panel. This avoids the drawback of traditional lamps that require matching light-transmitting covers to achieve the scattering effect, and avoids the problems of concentrated light and uneven illumination that may occur with traditional lamps. This improves the lighting quality and provides more comfortable and effective lighting for industrial working environments.

[0019] Furthermore, additional aspects and advantages of the present invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the present invention. Attached Figure Description

[0030] The following will provide a clear and complete description of the concept, specific structure, and technical effects of this utility model in conjunction with the embodiments and accompanying drawings, so as to fully understand the purpose, solution, and effects of this utility model. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0031] It should be noted that, unless otherwise specified, when a feature is referred to as "fixed" or "connected" to another feature, it can be directly fixed or connected to the other feature, or indirectly fixed or connected to the other feature. Furthermore, the descriptions of "upper," "lower," "left," "right," "top," and "bottom" used in this utility model are only relative to the relative positional relationships of the various components of this utility model in the accompanying drawings.

[0032] Furthermore, unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for the purpose of describing particular embodiments only and not for limiting the scope of the invention. The term "and / or" as used herein includes any combination of one or more of the associated listed items.

[0033] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various elements, these elements should not be limited to these terms. These terms are only used to distinguish elements of the same type from one another. For example, without departing from the scope of this disclosure, a first element may also be referred to as a second element, and similarly, a second element may also be referred to as a first element.

[0034] Reference Figure 1 and Figure 3 This embodiment provides a light panel, the specific structure of which is as follows:

[0035] LED Light Board 10: The light board is long and narrow, made of aluminum substrate, which has good heat dissipation performance and mechanical strength. The surface of the aluminum substrate is coated with a solder resist layer to prevent excessive solder diffusion during the soldering process, and also to provide some corrosion protection.

[0036] Reference Figure 1 The LED beads 11 shown are arranged on one side of the LED light panel 10 along the extension direction, forming at least one row. Figure 2 The LED beads can be arranged in two or more rows. These LED beads 11 are the main light-emitting elements of the lamp, and through uniform distribution, they can provide stable light output.

[0037] Reference Figure 1 Combination Figure 2The EVA adhesive layer 20 covers the LED light board 10 and LED beads 11, serving a sealing and protective function. EVA adhesive has good flexibility and waterproof properties, effectively preventing moisture and dust from entering the light board, while also buffering external physical impacts. The aforementioned light board and bead structure is covered with an epoxy resin adhesive layer. Compared to the EVA adhesive layer, the epoxy resin adhesive layer's high-temperature resistance further decreases under high-temperature conditions. Additionally, the light board and bead structure is covered with a silicone layer. While the silicone layer has better temperature resistance than the epoxy resin layer, it reduces the heat transmission capacity of the LED beads, leading to frequent LED bead failures. Furthermore, the light board and bead structure is covered with a nanomaterial coating, but this coating is expensive and has poor corrosion resistance. The light board and bead structure covered with an EVA adhesive layer overcomes the shortcomings of the aforementioned material layers, effectively making the light board dustproof, waterproof, moisture-proof, and preventing harmful substances from damaging the LED beads, thus effectively extending the lifespan of the lamp. For example, in high-temperature workshops where the ambient temperature can reach 100 degrees Celsius, LED light panels with EVA adhesive layers have been used for more than 4 months without being replaced.

[0038] Reference Figure 1 As shown in Figure 2, the edge of the EVA adhesive layer 20 on each LED bead 11 curves from the top of the LED bead 11 to the side edge of the LED light panel 10, forming an LED light-transmitting surface 21 for outward light diffusion. This structural design allows the LED beads along the side edge of the LED light panel 10 to diffuse light more evenly, improving the lighting effect of the lamp. The curved EVA adhesive layer 20 is also suitable for LED beads with three or more rows, further enhancing the outward diffusion of light.

[0039] In this embodiment, by using an aluminum substrate as the lamp board material and coating its surface with a solder resist layer, combined with the sealing protection of the EVA adhesive layer, the lamp board can resist the effects of high temperature, high humidity and corrosive environment to a certain extent, thus extending its service life.

[0040] Reference Figure 1 , 2 , Figure 5 and Figure 6 Based on embodiments 1 and 2, further improvements were made by adding a mating structure between the support housing 30 and the lamp panel:

[0041] Reference Figure 5As shown, the support housing 30 is engaged with the outer periphery of the LED light panel 10 to fix and support the light panel. The support housing 30 can be made of plastic or metal, depending on the usage environment and cost requirements. The inner surface of the support housing 30 is tightly fitted to the outer surface of the LED light panel 10 to ensure the stability of the light panel during installation and use.

[0042] In some embodiments, one end of the LED light panel 10 is provided with a power supply terminal, which is connected to a wiring terminal via a wire. This design facilitates the installation and maintenance of the light fixture, while also ensuring the reliability of the electrical connection.

[0043] The aforementioned lamp panel structure, by adding a supporting housing 30, is more stable and can better resist external physical impacts and vibrations. At the same time, the rational electrical connection design also improves the safety and reliability of the lamp.

[0044] Reference Figures 7 to 9 This embodiment 3 provides a lamp, the specific structure of which is as follows:

[0045] Reference Figure 7 As shown, the light-transmitting housing 40 is elongated and can be made of transparent or translucent plastic or glass, used for transmitting light. The shape and size of the light-transmitting housing 40 are designed according to actual usage requirements; for example, it can be flat or curved.

[0046] Reference Figure 7 The mounting housing 50 is sealed to the light-transmitting housing 40, and its inner wall is provided with mounting grooves 51 for fixing the lamp panel. The mounting housing 50 can be made of metal or plastic, depending on the usage environment and cost requirements.

[0047] Reference Figure 9 The sealing strip 60 shown: A sealing strip 60 is pressed at the connection between the mounting housing 50 and the light-transmitting housing 40 to improve the sealing performance of the lamp and prevent moisture and dust from entering the lamp.

[0048] Reference Figure 7 Combination Figure 8 The shown snap-fit ​​assembly 70 connects the outer walls of the mounting housing 50 and the light-transmitting housing 40 via multiple snap-fit ​​assemblies 70. Each snap-fit ​​assembly 70 includes a slot 71 and a spring-loaded snap fastener 72. The slot 71 is located on the outer wall of either the mounting housing 50 or the light-transmitting housing 40, and the spring-loaded snap fastener 72 is correspondingly located on the outer wall of either the light-transmitting housing 40 or the mounting housing 50. This snap-fit ​​connection method not only facilitates installation but also ensures a strong and reliable connection. Specifically, the spring-loaded snap fastener 72 can be designed as follows: Figure 8The bent metal structure in the middle has one end of its elastic buckle connected to the hinge of the outer wall of the mounting housing, making the part less likely to be lost. It is matched with the slot 71 of the light-transmitting housing 40, the shape of which matches the other end of the elastic buckle.

[0049] In this embodiment, by rationally designing the structure of the light-transmitting housing 40 and the mounting housing 50, and using the sealing strip 60 and the snap-fit ​​assembly 70 for sealing and fixing, the overall performance of the lamp is significantly improved. This structural design not only effectively prevents harmful substances such as moisture and dust from entering the lamp, but also improves the lamp's impact resistance and service life.

[0050] Reference Figure 10 This embodiment provides a lamp with a structure similar to that of Embodiment 3, but the connection method between the mounting housing 50 and the light-transmitting housing 40 differs: In this embodiment, the light-transmitting housing 40 and the mounting housing 50 are connected by adhesive sealing. Adhesive connection offers excellent sealing and anti-aging properties, making it suitable for environments with high sealing requirements. Simultaneously, adhesive connection simplifies the installation process and reduces production costs. Furthermore, the side of the light-transmitting housing 40 corresponding to the lamp panel is an outwardly convex arc surface. This arc surface design not only enhances the aesthetics of the lamp but also further optimizes the light scattering effect, resulting in a more uniform light distribution.

[0051] In this embodiment, the sealing performance and lighting effect of the luminaire are further optimized by employing adhesive bonding and a curved surface design. This structural design is particularly suitable for industrial environments with high requirements for sealing and lighting performance.

[0052] Based on the above embodiments, the structure of the luminaire is further optimized: the mounting housing 50 has a first end cap integrally formed at both ends, and the light-transmitting housing 40 has a second end cap integrally formed at both ends. This end cap design effectively prevents moisture and dust from entering from both ends of the luminaire, further improving the luminaire's sealing performance. Simultaneously, the end caps also provide a certain degree of protection, preventing the luminaire from being accidentally bumped or damaged during installation and use. By adding the end cap structure, the overall protective performance of the luminaire is significantly improved. This design is particularly suitable for harsh industrial environments and can effectively extend the luminaire's service life.

[0053] Based on the description of the above embodiments, the lamp panel and lamp fixture of this utility model have the following technical effects:

[0054] 1. Excellent sealing performance: By using EVA adhesive layer, sealing strip, snap-fit ​​components or adhesive connection method, the lamp can effectively prevent moisture and dust from entering the interior and adapt to high temperature, high humidity and corrosive environment.

[0055] 2. Optimized lighting effect: The curved light-transmitting surface design of the EVA adhesive layer and the curved structure of the light-transmitting shell enable light to diffuse outward more evenly, improving the lighting effect.

[0056] 3. Sturdy structural design: The combination of the supporting shell, snap-fit ​​components and end caps makes the lamp more stable during installation and use, and can resist external physical impacts and vibrations.

[0057] 4. Easy to install and maintain: The reasonable electrical connection design and snap-fit ​​connection method make the installation and maintenance of the lamps more convenient and quick, reducing the cost of use.

[0058] The above description is merely a preferred embodiment of this utility model. This utility model is not limited to the above-described embodiments. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this disclosure, as long as they achieve the same technical effect, should be included within the scope of protection of this disclosure and fall under the protection scope of this utility model. Within the protection scope of this utility model, the technical solutions and / or implementation methods can have various modifications and variations.
