Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and more specifically, to a refrigerator lighting tube. Background Technology

[0002] With the rapid development of the retail industry, supermarkets have increasingly higher requirements for display effects. In the fields of cold chain logistics and food preservation, refrigerators are key equipment for storing and displaying frozen foods, beverages, ice cream and other products. However, in the existing applications of supermarket refrigerator lighting, the light tubes cannot control the beam angle and light pattern, resulting in too low effective area illuminance and failing to highlight the lighting effect. Furthermore, the existing light tubes require the additional assembly of many parts, making the manufacturing process complex, with poor sealing and high production costs. In addition, due to the uneven refraction or reflection of light at the connection points of the existing light tubes, the light in the illuminated area is unevenly distributed, resulting in irregular yellow lines or shadows inside the refrigerator. This problem not only affects the lighting effect but may also affect the display effect of the products.

[0003] Therefore, this application proposes a refrigerator lighting tube to solve the problems existing in the prior art by making reasonable optical design of the tube structure and the position of the light source. Utility Model Content

[0004] This utility model aims to overcome at least one of the defects (deficiencies) of the prior art and provides a refrigerator lighting tube to solve the problems of the inability to control the light emission angle and light pattern of the refrigerator lighting tube and the yellow line generated by the tube structure connection line affecting the lighting and product display effect.

[0005] The technical solution adopted by this utility model is a refrigerator lighting tube, which includes: a lens, an LED light source module, a base, and a power supply component. The LED light source module is connected to the power supply component and is disposed in the base. The lens covers the light emission direction of the LED light source module and is mounted on the base. The lens is a mountain-shaped lens that splits the central light beam emitted by the LED light source module into two directions for refraction, left and right.

[0006] In this application, the lens is set as a mountain-shaped structure and covered in the light output direction of the LED light source module. By changing the lamp tube structure and the position of the light source, a reasonable optical structure is designed, so that the light beam generated by the LED light source module is split into left and right parts through the lens and refracted to the outside, thereby effectively increasing the effective lighting area, making the uniformity of the irradiated surface ≥80%, and improving the lighting effect.

[0007] Preferably, the mountain-shaped lens includes a recessed portion and an elongated protrusion. The recessed portion is located directly above the light-emitting direction of the LED light source module and is used to distribute the light beam emitted by the LED light source module. The elongated protrusion is located at the top of the lens and has an arc-shaped outer surface to improve light extraction efficiency.

[0008] In the lens, the recessed part covers the light-emitting direction of the LED light source module, which can directly distribute the strong light beam from the LED light source module. The light beam passes through the inside of the lens and is then refracted into the outside from the arc-shaped outer surface of the long strip-shaped protrusion, thereby effectively improving the optical transmittance of the lamp tube. The light emission efficiency is the highest when the light is perpendicular to the light emission interface, and then it diffuses outward, making the diffused light more uniform.

[0009] Preferably, the mountain-shaped lens is made of transparent material with added fog-diffusing powder to improve the optical effect of the lens.

[0010] In this application, using transparent material on the lamp lens can effectively improve light transmittance, help reduce light loss, and ensure that more light can pass through the lens effectively, thereby improving the overall luminous efficacy of the light source.

[0011] Furthermore, in the structure of lamp tubes, due to seams or uneven light distribution that may exist at the joints during the manufacturing process, these areas may produce noticeable yellow lines or bright spots, affecting the uniformity of lighting. To eliminate these uneven light effects, fogging powder is usually added to the lens. The function of this fogging powder is to scatter light when it passes through the lens, thereby eliminating the bright spot phenomenon at the seams or joints, thus achieving a more uniform light distribution. In this way, the yellow line phenomenon is eliminated, making the lighting effect softer and more uniform, and improving the visual experience.

[0012] Preferably, the base has a "U" shaped structure with protrusions on both sides inside. The protrusions and the lens disposed above form a slot, and the LED light source module is snapped into the slot.

[0013] The "U"-shaped base and protrusion design in this application simplifies the installation process, optimizes heat dissipation and optical effects by firmly fixing the LED light source module, and ensures precise alignment of the LED light source and lens, thereby improving the performance, stability and lifespan of LED lighting products.

[0014] Preferably, the base is white, and baffles are provided on both sides of the top of the base. When the baffles on both sides are unfolded outward, it is a double-sided light-emitting base; when one side baffle is set vertically upward and the other side baffle is unfolded outward, it is a single-sided light-emitting base.

[0015] By making the base white, diffuse reflection can be effectively achieved, helping to evenly disperse the light, making the light produced by the lamp tube softer, improving the overall luminous efficiency, ensuring that more light can be effectively utilized, and enhancing the brightness of the lighting. Furthermore, different bases are used to refract light, allowing the lamp tube to utilize different bases to control the emission angle and light pattern, thereby increasing the effective area illuminance of the refrigerator lamp tube.

[0016] Preferably, the lamp tube is installed in a lamp fixture inside the refrigerator by means of wall mounting or recessed installation. The refrigerator interior includes at least two lamp tubes with single-sided light-emitting bases and one lamp tube with double-sided light-emitting bases. In the lamp tube with single-sided light-emitting bases, the vertically upward baffle of the single-sided light-emitting base is fitted to the inner wall of the refrigerator. The lamp tube with double-sided light-emitting bases is located at the midpoint of the line connecting the installation positions of the two lamp tubes with single-sided light-emitting bases.

[0017] In this application, the lamp tube containing a double-sided light-emitting base can emit the light beam generated by the LED light source module in all directions, and then the two lamp tubes containing a single-sided light-emitting base reflect the light emitted from the lens, so that the light can be diffused towards the center of the refrigerator, thereby improving the lighting effect.

[0018] Preferably, the lamp tube is integrally formed by aluminum extrusion embedding.

[0019] The aluminum extrusion embedding method used in this application can effectively improve the strength of the lamp tube. In addition, aluminum alloy has good thermal conductivity. In electronic products or lighting products, aluminum extrusion embedding technology can significantly improve heat dissipation efficiency, reduce the operating temperature of the lamp tube, extend product life, and at the same time ensure that the lamp tube has good sealing performance, making it suitable for humid environments such as refrigerators.

[0020] Preferably, the LED light source module includes a heat dissipation circuit light strip and a number of LED beads, the LED beads being evenly distributed along the center line of the heat dissipation circuit light strip, and the two sides of the heat dissipation circuit light strip being snapped into the slots.

[0021] The light strip has good flexibility and can be easily installed into the slot. It also generates less heat, which helps to extend the life of the lamp tube. At the same time, several LED beads are evenly distributed on the light strip, making the light emitted from the lamp tube more uniform and softer, thereby improving the lighting effect.

[0022] Preferably, the base has power slots on both outer sides, which allow the lamp tube to be installed in a lamp fixture inside the refrigerator, thereby connecting to the power supply.

[0023] By using the power socket to install the lamp tube into the lamp, the stability of the circuit connection can be effectively ensured.

[0024] Preferably, the power supply assembly includes an overvoltage and overcurrent protection unit to prevent circuit failure from damaging the lamp tube.

[0025] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0026] 1. The beam is split by passing the central beam through the lamp tube structure to cause the beam to be refracted and reflected, splitting the light into two different directions, left and right.

[0027] 2. By combining frosted and transparent materials, the yellow lines caused by the junction lines of the lamp tube structure can be eliminated while improving luminous efficiency.

[0028] 3. The lamp tube is made by extruding aluminum and embedding it to enhance its strength. Attached Figure Description

[0033] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this invention. To better illustrate the following embodiments, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0034] Example 1

[0035] like Figures 1-3 As shown, this embodiment provides a refrigerator lighting tube, which includes: a lens 1, an LED light source module 2, a base 3, and a power supply component 4. The LED light source module 2 is connected to the power supply component 4 and is disposed in the base 3. The lens 1 covers the light emission direction of the LED light source module 2 and is mounted on the base 3. The lens 1 is a mountain-shaped lens, which splits the central beam emitted by the LED light source module 2 into two directions for refraction, left and right.

[0036] In this embodiment, the lens 1 is configured as a mountain-shaped structure and covers the light-emitting direction of the LED light source module 2. By changing the lamp tube structure and the position of the light source, a reasonable optical structure is designed, so that the light beam generated by the LED light source module 2 is split into left and right parts through the lens 1 and refracted to the outside, thereby effectively increasing the effective lighting area and improving the lighting effect.

[0037] Preferably, such as Figure 1 or Figure 2 As shown, the mountain-shaped lens includes a recessed portion 11 and an elongated protrusion 12. The recessed portion 11 is located directly above the light-emitting direction of the LED light source module 2 and is used to distribute the light beam emitted by the LED light source module 2. The elongated protrusion 12 is located on the top of the lens and has an arc-shaped outer surface to improve the light output efficiency.

[0038] In the lens 1, the recessed portion 11, positioned directly above the LED light source module 2 in the direction of light emission, can directly distribute the strong light beam from the LED light source module 2. The light beam passes through the interior of the lens 1 and is then refracted to the outside through the arc-shaped outer surface of the elongated protrusion 12, thereby effectively improving the optical transmittance of the lamp tube. The light emission efficiency is highest when the light is perpendicular to the light emission interface. Figure 3 As shown, the light beam emitted by the LED light source module 2 enters the interior of the lens 1 through the vertical recess 11, and then, under the refraction of the lens 1, it is refracted perpendicularly to the arc-shaped outer surface of the lens 1 before being scattered outwards. This makes the scattered light more uniform and ensures that all the light beam emitted by the LED light source module 2 is emitted, thereby improving the light output efficiency.

[0039] Preferably, the mountain-shaped lens is made of transparent material with added fog-diffusing powder to improve the optical effect of lens 1.

[0040] In this embodiment, the transparent material used on the lamp lens 1 is typically high-quality plastic, which can effectively improve light transmittance. The transparent material helps reduce light loss and ensures that more light can pass through the lens effectively, thereby improving the overall luminous efficiency of the light source. This design ensures that the lamp provides brighter light output without increasing energy consumption.

[0041] Furthermore, in the structure of lamp tubes, due to seams or uneven light distribution that may exist at the joints during the manufacturing process, these areas may produce noticeable yellow lines or bright spots, affecting the uniformity of lighting. To eliminate these uneven light effects, fogging powder is usually added to the lens. The function of this fogging powder is to scatter light when it passes through the lens, thereby eliminating the bright spot phenomenon at the seams or joints, thus achieving a more uniform light distribution. In this way, the yellow line phenomenon is eliminated, making the lighting effect softer and more uniform, and improving the visual experience.

[0042] Preferably, the base 3 has a "U" shaped structure with protrusions 31 on both sides inside. The protrusions and the lens set above form a slot, and the LED light source module 2 is snapped into the slot.

[0043] The "U"-shaped base 3 and protrusion 31 provided in this embodiment offer a slot for the LED light source module 2. This slot design ensures that the LED light source module 2 is firmly fixed to the base, preventing loosening or displacement due to vibration or external force, thus guaranteeing the stability and long-term reliability of the LED light source. Furthermore, this slot design simplifies the installation process of the LED light source module 2. Since the LED light source module 2 can be easily snapped into the slot, the complex fixing process is reduced, improving production and installation efficiency. In addition, fixing the LED light source module 2 in the slot also aids in lens positioning, ensuring precise alignment between the LED light source and lens 1. Correct alignment helps in accurate light propagation, avoiding light deviation or distortion caused by misalignment between the light source and lens 1, further improving the uniformity and quality of the lighting effect, and preventing light spots or uneven illumination.

[0044] Preferably, the base 3 is white, and baffles are provided on both sides of the top of the base 3. When the baffles on both sides are unfolded outward, it is a double-sided light-emitting base; when one side baffle is set vertically upward and the other side baffle is unfolded outward, it is a single-sided light-emitting base.

[0045] By making the base 3 white, diffuse reflection can be effectively achieved, reflecting more light, reducing light loss, and helping to evenly disperse the light, making the light produced by the lamp tube softer, improving the overall luminous efficiency, ensuring that more light can be effectively utilized, and enhancing the brightness of the lighting. The white surface can also reflect most of the light and heat, reducing the heat absorbed by the base 3, helping heat dissipation, and preventing the LED light source from reducing efficiency or affecting its lifespan due to overheating. Furthermore, this embodiment also uses different bases 3 to refract light, allowing the lamp tube to use different bases to control the emission angle and light pattern, thereby improving the effective area illuminance of the refrigerator lamp tube.

[0046] Preferably, such as Figure 3 As shown, the lamp tube is installed in the light fixture inside the refrigerator by means of wall mounting or recessed installation. The refrigerator interior includes at least two lamp tubes with single-sided light-emitting bases and one lamp tube with double-sided light-emitting bases. In the lamp tube with single-sided light-emitting bases, the vertically upward baffle of the single-sided light-emitting base is fitted to the inner wall of the refrigerator. The lamp tube with double-sided light-emitting bases is located at the midpoint of the line connecting the installation positions of the two lamp tubes with single-sided light-emitting bases.

[0047] In this embodiment, as Figure 3 As shown, the lamp tube in the middle, which includes a double-sided light-emitting base, emits the light beam generated by the LED light source module 2 in all directions, dispersing the light evenly to the center of the refrigerator and its surroundings. At the same time, the lamp tubes on both sides, which include a single-sided light-emitting base, directly emit the light from the side closest to the center of the refrigerator. The light from the other side changes its propagation path under the reflection of the vertical baffle, causing the light to also diffuse towards the center. This allows the light to cover the entire interior of the refrigerator, effectively increasing the effective area illuminance and improving the lighting effect.

[0048] Preferably, the lamp tube is integrally formed by aluminum extrusion embedding.

[0049] In this embodiment, the aluminum extrusion embedding method is used to process the lamp tube, which can effectively improve the strength of the lamp tube. In addition, aluminum alloy has good thermal conductivity. In electronic products or lighting products, aluminum extrusion embedding technology can significantly improve heat dissipation efficiency, reduce the operating temperature of the lamp tube, and extend the product life. At the same time, it can also help hide seams or reduce visible joints, ensuring that the lamp tube has good sealing performance, which is suitable for humid environments such as refrigerators.

[0050] Preferably, the LED light source module 2 includes a heat dissipation circuit light strip and a number of LED beads, the LED beads being evenly distributed along the center line of the heat dissipation circuit light strip, and the two sides of the heat dissipation circuit light strip being snapped into the slots.

[0051] The light strip has good flexibility and can be easily installed into the slot. It also generates less heat, which helps extend the life of the lamp tube. At the same time, several LED beads are evenly distributed on the light strip, making the light emitted from the lamp tube more uniform and softer, thereby improving the lighting effect. In addition, the light strip is waterproof (such as IP65 or higher waterproof rating), making it suitable for outdoor or humid environments, such as in refrigerated environments like refrigerators.

[0052] Preferably, the base 3 has power slots 32 on both sides of its exterior, which allow the lamp tube to be installed in the lamp fixture inside the refrigerator, thereby connecting the power supply.

[0053] In this embodiment, the design of the power slot 32 simplifies the connection process between the lamp tube and the internal lighting fixture of the refrigerator. Users simply insert the lamp tube into the slot to complete the power connection, reducing the complexity of traditional wiring and improving installation efficiency. Furthermore, the slot design reduces the use of exposed wires, preventing wires from being exposed externally and effectively reducing the risk of electric shock or short circuits in the humid environment of the refrigerator. The power connection is more stable and safer by fixing the position of the power slot 32. At the same time, the power slot 32 also ensures that the lamp tube can stably receive power when installed in the refrigerator lighting fixture, preventing the lamp tube from malfunctioning due to poor contact, thereby improving the reliability and long-term performance of the device.

[0054] Preferably, the power supply assembly includes an overvoltage and overcurrent protection unit to prevent circuit failure from damaging the lamp tube.
