[0026] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0027] Reference below Figures 1 to 3 The present invention provides a double-sided luminous LED tube lamp and a refrigerator lighting device.

[0028] like Figures 1 to 3 As shown, the double-sided LED tube lamp according to the embodiment of the first aspect of the present invention can be used in a refrigerator, which can improve the lighting effect and product display effect, facilitate consumers to select products, and help promote product sales.

[0029] The double-sided LED tube light has a first direction, a second direction, and a third direction. The first direction, the second direction, and the third direction are perpendicular to each other. For a clearer understanding of this embodiment, assume that the first direction is the up-down direction, the second direction is the left-right direction, and the third direction is the front-back direction.

[0030] like Figures 1 to 3 As shown, the structure of the double-sided emitting LED tube lamp includes a lamp housing 100 and an LED lamp panel assembly 400 .

[0031] The lamp housing 100 includes a lamp holder 110, a first lampshade 120, and a second lampshade 130. The lamp holder 110 extends in a first direction, and the first and second lampshades 120 and 130 also extend in the first direction. The first and second lampshades 120 and 130 are respectively provided on adjacent sides of the lamp holder 110. Both the first and second lampshades 120 and 130 are connected to the lamp holder 110, so that the lamp holder 110, the first and second lampshades 120 and 130 collectively define a receiving cavity 140, which extends in the first direction.

[0032] Furthermore, the first lampshade 120 has a convex, transparent structure. Specifically, the first lampshade 120 is a hemispherical convex, transparent structure. The thickness of the first lampshade 120 is thicker in the middle and thinner at the sides, which can focus light. The second lampshade 130 has a square cross-section and is uniformly thick, that is, the thickness of the second lampshade 130 is consistent throughout.

[0033] It will be appreciated that the shape of the lamp housing 100 can be arbitrarily set according to practical circumstances. In this embodiment, the lamp base 110 has a square cross-section. The first lampshade 120 is located on one side of the lamp base 110 in the second direction, and the second lampshade 130 is located on the other side of the lamp base 110 in the third direction. The lamp base 110, the first lampshade 120, and the second lampshade 130 are an integrated structure, that is, the lamp housing 100 is an integrated structure and can be manufactured through an integrated extrusion process. Furthermore, the lamp housing 100 is made of transparent PC (i.e., polycarbonate). Furthermore, the first lampshade 120 and the second lampshade 130 are protruding. Therefore, when viewed along the first direction, the cross-section of the lamp housing 100, which is composed of the first lampshade 120, the second lampshade 130, and the lamp base 110, is L-shaped.

[0034] Of course, it is not ruled out that in other embodiments, the first lampshade 120 and the second lampshade 130 are fixed to the lamp holder 110 by bonding, snap connection, etc., and the lamp holder 110 is made of the same or different materials as the first lampshade 120 and the second lampshade 130. The first lampshade 120 and the second lampshade 130 can also be made of other transparent materials.

[0035] Two groups of LED light panel assemblies 400 are provided, and both groups of LED light panel assemblies 400 are disposed within the accommodating cavity 140 of the lamp housing 100, thereby providing excellent protection. The light emission directions of the two groups of LED light panel assemblies 400 are perpendicular to each other. Specifically, the light emission direction of one group of LED light panel assemblies 400 extends along the second direction, while the light emission direction of the other group of LED light panel assemblies 400 extends along the third direction. Furthermore, one group of LED light panel assemblies 400 is disposed directly opposite the first lampshade 120, and the length of this group of LED light panel assemblies 400 can be equal to or less than the length of the first lampshade 120; the other group of LED light panel assemblies 400 is disposed directly opposite the second lampshade 130, and the length of this group of LED light panel assemblies 400 can be equal to or less than the length of the second lampshade 130.

[0036] It is understood that each set of LED light panel assemblies 400 may include at least one LED light panel assembly 400. Each LED light panel assembly 400 comprises a PCB (Printed Circuit Board) and multiple LED lamp beads, which are arranged at regular intervals along the extension direction of the PCB. When the LED light panel assembly 400 positioned opposite the first lampshade 120 is in operation, light emitted by the LED lamp beads passes through the first lampshade 120 and radiates outward. When the LED light panel assembly 400 positioned opposite the second lampshade 130 is in operation, light emitted by the LED lamp beads passes through the second lampshade 130 and radiates outward.

[0037] In some examples, the corners of the second lampshade 130 are right angles. In other examples, such as Figure 3 As shown, the corners of the second lampshade 130 are rounded. By adopting a rounded transition design for the corners of the second lampshade 130, the corners of the second lampshade 130 become smooth and without sharp corners, improving the aesthetics. The surface of the second lampshade 130 opposite to the LED light panel assembly 400 is flat.

[0038] In some embodiments, as Figure 3 As shown, the lamp holder 110 is provided with a slot 111. The length of the slot 111 extends along a first direction and passes through both end surfaces of the lamp holder 110 along the first direction. Specifically, the inner sidewall of the lamp holder 110 is formed with a plurality of stoppers, wherein two oppositely disposed stoppers jointly define the slot 111. There are two slots 111, each corresponding to two sets of LED light panel assemblies 400. Each set of LED light panel assemblies 400 is configured to snap into a corresponding slot 111. This design facilitates disassembly and replacement of the LED light panel assemblies 400.

[0039] In some embodiments, end plates are provided at both ends of the lamp holder 110 along the first direction, and the end plates and the lampshade are fixedly connected by an integral molding process or a bolt connection method.

[0040] In other embodiments, Figure 1 and Figure 2 As shown, the structure of the double-sided LED tube lamp also includes a plug 200. The plugs 200 are provided at both ends of the lamp housing 100. The end of the plug 200 close to the lamp housing 100 is provided with a groove 220. The opening of the groove 220 is open toward the lamp housing 100. The cross-sectional shape of the groove 220 matches the cross-sectional shape of the lamp housing 100. During assembly, one end of the lamp housing 100 is inserted into the groove 220 of one of the plugs 200, and the opposite end of the lamp housing 100 is inserted into the groove 220 of the other plug 200.

[0041] It is understood that the plug 200 can be made of plastic material, and the overall shape of the plug 200 can be selected according to actual design requirements and is not specifically limited here. The lamp housing 100 and the groove 220 of the plug 200 can be, but not limited to, an interference fit connection.

[0042] Furthermore, the plug 200 has a mounting hole 210 for the screw 500. The mounting hole 210 is located at the end of the plug 200 away from the lamp housing 100, and the central axis of the mounting hole 210 extends along the second direction. The mounting hole 210 can be a round hole or a waist-shaped hole. Therefore, when the double-sided LED lamp is installed in a refrigerator, the screw 500 is passed through the mounting hole 210 of the plug 200 and threadedly connected to the refrigerator, ensuring that the plug 200 is firmly fixed inside the refrigerator.

[0043] Furthermore, the structure of the double-sided LED tube lamp also includes an electrical connector 300. The plug 200 is provided with a through hole, located on the surface of the plug 200 away from the lamp housing 100. The central axis of the through hole extends along a first direction, and the through hole is interconnected with the accommodating cavity 140 of the lamp housing 100. The through hole can be a circular hole, capable of passing the wire of the electrical connector 300. Therefore, one end of the electrical connector 300 can pass through the through hole and electrically connect to the LED light board assembly 400 in the accommodating cavity 140, thereby providing power to the LED light board assembly 400.

[0044] It is understood that the electrical connector 300 can be a male waterproof connector. One electrical connector 300 can be provided for each LED light panel assembly 400. All electrical connectors 300 can be provided on the same side of one plug 200, or can be provided corresponding to two plugs 200. The wires of the electrical connectors 300 can be routed within the accommodating cavity 140 of the lamp housing 100.

[0045] In the double-sided luminous LED tube lamp provided in the embodiment of the present invention, a lamp housing 100 extending in a first direction and having a accommodating cavity 140 is formed by a lamp holder 110, a first lampshade 120 and a second lampshade 130. Two groups of LED lamp panel assemblies 400 with mutually perpendicular luminous directions are arranged in the accommodating cavity 140 of the lamp housing 100. Moreover, one group of LED lamp panel assemblies 400 is arranged opposite to the first lampshade 120 with a convex structure, and the other group of LED lamp panel assemblies 400 is arranged opposite to the second lampshade 130 with a square cross-sectional shape.

[0046] Then, when using the double-sided LED tube lamp, the light emitted by one group of LED light panel assemblies 400 will pass through the first lampshade 120 of the convex structure. The first lampshade 120 can converge the light, forming a more concentrated lighting area, and increase the brightness of the light. Through the cooperation of this group of LED light panel assemblies 400 and the first lampshade 120, it can play the role of main lighting in the front row of the refrigerator door, improve the effect of product display, and produce a strong visual impact, better arouse consumers' desire to buy, and promote product sales.

[0047] At the same time, the light emitted by another group of LED light panel assemblies 400 will pass through the second lampshade 130 with a square cross-section. The second lampshade 130 can evenly diverge the light to form an evenly illuminated lighting area. Through the cooperation of this group of LED light panel assemblies 400 and the second lampshade 130, it can play an auxiliary lighting role on the longitudinal inner wall of the refrigerator, further enhancing the effect of product display and making it easier for consumers to obtain products deep inside the refrigerator.

[0048] like Figures 1 to 3 As shown, the refrigerator lighting device according to the second embodiment of the present invention includes the double-sided LED tube light and a control switch as described in the first embodiment. The control switch can control the on and off of the double-sided LED tube light.

[0049] In the refrigerator lighting device, the number of double-sided LED tube lights is not limited to one. Specifically, double-sided LED tube lights can be installed on the left and right inner side walls of the refrigerator, or on the inner upper wall of the refrigerator.

[0050] It is understood that in a double-sided LED tube light, the two sets of LED light panel assemblies 400 emit light in perpendicular directions. Therefore, the double-sided LED tube light can provide both lateral and vertical directional lighting functions. These two directions can be illuminated according to different lighting performance requirements, and can play the role of primary lighting and auxiliary lighting in the refrigerator. Within the refrigerator, different areas also have different lighting performance requirements.

[0051] Specifically, the double-sided LED tube light can be fixed to the center beam inside the refrigerator by screws 500 and installed in an embedded manner. Under the premise of meeting the lighting requirements, the double-sided LED tube light can be hidden, so that the lighting of the refrigerator can be seen without seeing the lamp, making the visual environment atmosphere softer, warmer and more comfortable, and more conducive to highlighting the items in the refrigerator.

[0052] When the double-sided LED tube light is working, both groups of LED light panel assemblies 400 will emit light. The light emitted by one group of LED light panel assemblies 400 penetrates the first lampshade 120 of the convex structure. The first lampshade 120 can play a role in converging light, forming a more concentrated lighting area and increasing the brightness of the light. Therefore, the first lampshade 120 cooperates with the corresponding LED light panel assembly 400 to play the role of main lighting in the front row of the refrigerator door. The lighting effect is good, the brightness is high, and there is a sense of visual impact. The lighting area is the consumer's first perspective, which can better arouse the consumer's desire to buy and promote product sales.

[0053] At the same time, the light emitted by another set of LED light panel components 400 will penetrate the second lampshade 130. The second lampshade 130 can play a role in evenly dispersing the light, forming an evenly illuminated illumination area. Therefore, the second lampshade 130 cooperates with the corresponding LED light panel component 400 to play an auxiliary lighting role on the deep inner wall of the refrigerator, allowing appropriate light to illuminate the inner wall of the refrigerator, thereby creating a visual light sensation in the originally relatively dark area and increasing the illumination. Under bright lighting conditions, it becomes easier for consumers to request and select items deep inside the refrigerator.

[0054] Compared with the relatively simple lighting of the interior of the refrigerator by a single lamp in the prior art, the refrigerator lighting equipment of this embodiment can use the two adjacent surfaces within the accommodating cavity 140 of the double-sided LED tube lamp to set the internal light source. While meeting the main lighting of the refrigerator, it also takes into account the lighting needs of another area on the inner wall of the refrigerator, thereby improving the overall lighting effect of the refrigerator space.

[0055] The double-sided LED tube light is installed on the center beam inside the refrigerator and adopts an integrated structural design with the center beam. It can be easily installed symmetrically, optimize the power system, reduce the layout of lines, save the cost of the refrigerator, and improve assembly efficiency.

[0056] The refrigerator lighting equipment adopts the double-sided luminous LED tube lamp of the above structure. When the refrigerator lighting equipment is installed in the refrigerator, it can improve the lighting effect. Moreover, the lighting range is fully covered without blind spots, and the goods in the refrigerator can be clearly displayed, making it convenient for consumers to select goods.
