Description

Technical Field

[0001] The present invention belongs to the technical field of LED linear lights, and specifically relates to a low-cost LED linear light that is easy to dissipate heat. Background Art

[0002] The LED linear light series is a high-end flexible decorative light featuring low power consumption, long life, high brightness, easy bending, and maintenance-free design. It is particularly suitable for indoor and outdoor entertainment venues, building outlines, and billboards. Available in 12V and 24V versions, and in lengths of 30cm, 60cm, 90cm, and 120cm, the product is also customizable to meet customer needs.

[0003] In the prior art, an LED stripe with patent publication number CN204005458U is disclosed. By mounting the LED lamp on a first side and disposing a heat dissipation unit on a second side, the stripe has a simple structure, is easy to assemble, and has low cost. Furthermore, the heat dissipation unit can dissipate heat promptly, providing good heat dissipation. However, in actual use, the stripe still has the following deficiencies: Practically speaking, heat dissipation relies solely on heat dissipation holes on one side, resulting in poor efficiency.

[0004] Therefore, a low-cost and easy-to-dissipate heat LED linear light is needed to solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this new technology is to provide a low-cost LED linear light with easy heat dissipation to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a low-cost, easy-to-dissipate LED linear light, comprising a base, the base being U-shaped, and a plurality of symmetrical first connection holes being provided on the upper ends of both sides of the U-shaped base, the plurality of symmetrical first connection holes being fixedly connected to the outer shell by bolts, the outer shell being U-shaped, and a bottom plate being fixedly connected to the middle of the inner surface of the lower end of the outer shell, the upper end of the bottom plate being fixedly connected to the LED line through a plurality of fixing members, the upper end of the LED line being provided with a plurality of lamp holders, and the lower end of the bottom plate being fixedly connected to a plurality of heat sinks, the plurality of heat sinks being penetrated and slidably connected to a plurality of through grooves provided at the lower end of the outer shell, and the lower ends of the front and rear sides of the outer shell being fixedly connected to the lampshade through a plurality of limit assemblies.

[0007] It should be noted that a groove is provided at the lower end of the U-shaped base.

[0008] It is further worth noting that the upper surface of the lower end of the U-shaped base is fixedly connected to a limiting plate on one side of the two end side plates. If the height of the limiting plate is H1, and the length of several heat sinks extending from the lower surface of the lower end of the base plate is H2, then H1 is slightly greater than or equal to H2.

[0009] It should be further explained that there are card slots at the lower ends of the front and rear sides of the shell, and the inner surfaces of the lower ends of both sides of the lampshade are fixedly connected with protruding guides, the card slots and protruding guides are symmetrically semicircular, and the inner surfaces of the card slots can be symmetrically fitted and slidably connected to the corresponding protruding guide front ends.

[0010] As a preferred embodiment, several of the limiting assemblies include a connecting plate, which is L-shaped, and one side of the lower end of the L-shaped connecting plate is fixedly connected to the lower ends of the front and rear sides of the shell, and a threaded hole is provided in the middle of the upper end of the L-shaped connecting plate, and the threaded holes are threadedly connected to threaded shafts, the front ends of the threaded shafts are fixedly connected to connecting heads, and the rear ends of the threaded shafts are fixedly connected to nuts.

[0011] As a preferred embodiment, the connector and the slot or protrusion guide are located in the same plane.

[0012] As a preferred embodiment, the connections between the plurality of heat sinks located outside the through slots of the housing are sealed by sealant.

[0013] Compared with the existing technology, the present invention provides a low-cost and easy-to-dissipate heat LED linear light, which has at least the following beneficial effects:

[0014] (1) By rotating the threaded shafts of several limit assemblies, the raised guides of the lampshade can be made to fit more closely with the slots provided on both sides of the shell, thereby making the connection between the shell and the lampshade tighter, that is, increasing the airtightness after the connection between the two, isolating the lampshade from contact with external moisture, and achieving a waterproof effect.

[0015] (2) The base plate and the heat sink are made of aluminum alloy. Although the thermal conductivity of aluminum alloy is lower than that of copper and silver, it is completely sufficient for the heat dissipation of the LED line light, thereby reducing the cost of the heat dissipation component of the LED line light. At the same time, the heat sinks are all penetrated and slidably connected to the through grooves provided at the lower end of the shell, which can increase the natural contact area with the air and thus increase the natural heat dissipation efficiency of the LED line light.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] See also Figure 1-4 The present invention provides a low-cost and easy-to-dissipate LED linear light, comprising: a base 1, the base 1 is U-shaped, and the upper ends of both sides of the U-shaped base 1 are provided with a plurality of symmetrical first connection holes 102, and the plurality of symmetrical first connection holes 102 are fixedly connected to the shell 2 by bolts 103, and the plurality of symmetrical second connection holes 201 are provided on both sides. The shell 2 is U-shaped, and the middle part of the inner surface of the lower end of the shell 2 is fixedly connected to the bottom plate 3, the upper end of the bottom plate 3 is fixedly connected to the LED line 4 by a plurality of fixing members 401, the upper end of the LED line 4 is provided with a plurality of lamp holders 5, and the lower end of the bottom plate 3 is fixedly connected to a plurality of heat sinks 301, and the plurality of heat sinks 301 are all penetrated and slidably connected to a plurality of through grooves 203 provided at the lower end of the shell 2, and the lower ends of the front and rear sides of the shell 2 are fixedly connected to the lampshade 7 by a plurality of limit assemblies 6.

[0023] Further as Figure 1 and Figure 2 As shown, it is worth mentioning that a groove 101 is provided at the lower end of the U-shaped base 1, through which the lamp can be hidden and the direction of light can be changed.

[0024] Further as Figure 1 and Figure 2As shown, it is worth mentioning that the upper surface of the lower end of the U-shaped base 1 is fixedly connected to a limiting plate 104 on one side of the side plates at both ends. If the height of the limiting plate 104 is H1, and the length of the plurality of heat sinks 301 extending from the lower surface of the lower end of the base plate 3 is H2, then H1 is slightly greater than or equal to H2. By setting the limiting plate 104 and comparing it with the length of the plurality of heat sinks 301 extending from the lower surface of the lower end of the base plate 3, the lower ends of the plurality of heat sinks 301 and the U-shaped base 1 can be prevented from being squeezed.

[0025] Further as Figure 1 and Figure 2 As shown, it is worth mentioning that a card slot 202 is provided at the lower ends of the front and rear sides of the shell 2, and the inner surfaces of the lower ends of the lampshade 7 on both sides are fixedly connected with a protruding guide 701, the symmetrical card slots 202 and the protruding guide 701 are both semicircular, and the inner surfaces of the symmetrical card slots 202 can be fitted and slidably connected to the front ends of the corresponding protruding guides 701. Through the shape and connection relationship of the symmetrical card slots 202 and the protruding guides 701, the connection between the shell 2 and the lampshade 7 can be made tighter, which increases the airtightness of the two after connection, isolates them from contact with external moisture, and achieves a waterproof effect.

[0026] This solution has the following working process: first, the lampshade 7 is fitted and installed on both sides of the shell 2, and then by rotating the threaded shafts 603 of several limit components 6, the raised guide 701 of the lampshade 7 can be more closely fitted into the slots 202 provided on both sides of the shell 2, and finally, several second connection holes 201 on both sides of the shell 2 and several first connection holes 102 on both sides of the base 1 are fixedly connected to each other through several bolts 103.

[0027] According to the above working process, it can be known that: through the groove 101, it is convenient to hide the lamp and change the direction of the light. Through the setting of the limit plate 104 and the comparison of its length with the lower surface of the lower end of the bottom plate 3 with the plurality of heat sinks 301, it can prevent the lower ends of the plurality of heat sinks 301 from being squeezed with the U-shaped base 1. Through the shape and connection relationship of the symmetrical card groove 202 and the raised guide 701, the connection between the shell 2 and the lampshade 7 can be made tighter, which not only increases the airtightness after the connection between the two, but also isolates the contact with external moisture to achieve a waterproof effect.

[0028] Further as Figure 4As shown, it is worth mentioning that several limiting components 6 include a connecting plate 601, which is L-shaped, and one side of the lower end of the L-shaped connecting plate 601 is fixedly connected to the lower ends of the front and rear sides of the shell 2, and a threaded hole 602 is provided in the middle of the upper end of the L-shaped connecting plate 601, and the threaded holes 602 are threadedly connected to a threaded shaft 603, and the front ends of the threaded shafts 603 are fixedly connected to a connector 604, and the rear ends of the threaded shafts 603 are fixedly connected to a nut 605. Through several limiting components 6, not only the looseness of the connection between the shell 2 and the lampshade 7 can be controlled, but the lampshade 7 can also be fixed on the shell 2, thereby increasing the airtightness after the connection between the two, isolating the contact with external moisture, and achieving a waterproof effect.

[0029] Further as Figure 1 and Figure 2 As shown, it is worth mentioning that the connector 604 and the slot 202 or the protruding guide 701 are all located in the same plane. The positional relationship between the connector 604 and the slot 202 or the protruding guide 701 facilitates the efficiency of several limiting components 6.

[0030] Further as Figure 3 As shown, it is worth mentioning that the connections between the plurality of heat sinks 301 located outside the through slots 203 of the outer shell 2 are sealed by sealant, which can isolate the heat sinks 301 from contact with external moisture and achieve a waterproof effect.

[0031] In summary: first, the lampshade 7 is fitted and installed on both sides of the shell 2, and then the threaded shafts 603 of the limiting components 6 are rotated to make the raised guides 701 of the lampshade 7 fit more closely with the card slots 202 provided on both sides of the shell 2, and finally the second connecting holes 201 on both sides of the shell 2 and the first connecting holes 102 on both sides of the base 1 are fixedly connected to each other through the bolts 103. Through the limiting components 6, not only the looseness of the connection between the shell 2 and the lampshade 7 can be controlled, but also the lampshade 7 can be fixed on the shell 2, thereby increasing the airtightness after the connection between the two, isolating the contact with external moisture, and achieving a waterproof effect. The positional relationship between the connector 604 and the card slot 202 or the raised guide 701 facilitates the efficiency of the limiting components 6, and the connection between the heat sinks 301 on the outside of the through groove 203 of the shell 2 is sealed with sealant, which can isolate the contact with external moisture and achieve a waterproof effect.
