DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] Please see attached Figure 1-3 The utility model provides a double-side power-connected linear light, comprising a lamp housing 100, a lamp belt 200, a lamp shade 300, and a power connection terminal 400; the lamp housing 100 comprises a lamp housing bottom edge 110, a first lamp housing side edge 120 connected to one side of the lamp housing bottom edge 110, and a second lamp housing side edge 130 connected to the other side of the lamp housing bottom edge 110; the lamp belt 200 comprises a flexible circuit board 210, a plurality of LED lamp beads 220 arranged at intervals in the middle of the flexible circuit board 210, and a plurality of LED lamp beads 220 arranged at intervals in the middle of the flexible circuit board 210. 0, and a conductive layer 230 arranged on both sides of the flexible circuit board 210, the middle part of the flexible circuit board 210 is attached to the bottom edge 110 of the lamp housing, and the two sides of the flexible circuit board 210 are respectively attached to the first lamp housing side 120 and the second lamp housing side 130; the lampshade 300 is connected between the first lamp housing side 120 and the second lamp housing side 130; the power terminal 400 is plugged into the end of the lamp housing 100 and electrically connected to the conductive layer 230.

[0031] In the light strip 200, the flexible circuit board 210 mainly uses polyimide or polyester film as a substrate. These materials have excellent flexibility and high temperature resistance, so that the flexible circuit board 210 can be bent inside the lamp housing 100. The conductive layer 230 on the flexible circuit board 210 usually uses copper foil, and its thickness can be adjusted as needed, usually between a few microns and tens of microns.

[0032] It is understandable that, by utilizing the softness of the flexible circuit board 210, the surface of the flexible circuit board 210 is divided into a connected middle part and two side parts, only to distinguish the layout positions of the conductive layer 230 and the LED lamp beads 220, and does not mean that the three parts are used as independent components. In fact, the flexible circuit board 210 is still a whole, which can be bent and cut to adapt to lamp housings 100 of different lengths and shapes.

[0033] In the present application, copper foil is arranged on both sides of the flexible circuit board 210, so that the middle part of the flexible circuit board 210 loaded with LED lamp beads 220 is adhered to the bottom edge 110 of the lamp housing, and the two side parts loaded with the conductive layer 230 are adhered to the first lamp housing side 120 and the second lamp housing side 130, and the two conductive layers 230 are transferred from the bottom of the lamp housing 100 to the two sides of the lamp housing 100, and then the end of the lamp housing 100 is sealed with the power terminal 400 and electrically connected to the conductive layer 230 to realize the power supply of the linear lamp; the above structure shortens the width of the lamp housing 100 without changing the height of the lamp housing 100, so that it is suitable for narrow installation space.

[0034] Specifically, a power connection terminal 400 is disposed at both ends of the lamp housing 100 , and one of the power connection terminals 400 is connected to a power source, so that a complete circuit is formed between the light strip 200 and the power source, and the light strip 200 emits light.

[0035] Please refer to the attached Figure 3 and attached Figure 4 A first notch 121 is provided on the side edge 120 of the first lamp housing, a second notch 131 is provided on the side edge 130 of the second lamp housing, and two sides of the lampshade 300 are respectively inserted into the first notch 121 and the second notch 131 .

[0036] In the present application, the lampshade 300 is in the shape of a strip plate, and the light emitted by the LED lamp beads 220 on the light strip 200 passes through the lampshade 300 to form light to illuminate the space that needs lighting; a channel for accommodating the lampshade 300 is formed by the first notch 121 and the second notch 131, so that the lampshade 300 can be disassembled and assembled from any end of the lamp housing 100 by pulling and pulling, and the lampshade 300 is blocked by cooperating with the power connection terminal 400 at the end of the lamp housing 100, so that there is no need for bolts or other fixing parts to fix it, which not only saves drilling, but also makes disassembly and assembly convenient and quick, and also ensures the structural strength of the linear lamp.

[0037] In a specific embodiment, the first notch 121 and the second notch 131 are at the same height; when the first notch 121 and the second notch 131 are at the same height, it means that the lampshade 300 is parallel to the bottom edge 110 of the lamp housing when installed, and the light is stronger at a position level with the lampshade 300.

[0038] In another specific embodiment, the first notch 121 and the second notch 131 are not at the same height; when the first notch 121 and the second notch 131 are not at the same height, it means that the lampshade 300 is arranged at an angle with the bottom edge 110 of the lamp shell when installed, and the lampshade 300 refracts the light emitted by the LED lamp beads to avoid glare when viewing the line light.

[0039] In order to facilitate the lamp housing 100 to be mounted and clipped to the required installation position, as shown in the attached Figure 3 and attached Figure 4 As shown, an edge of the first lamp housing side 120 and / or an edge of the second lamp housing side 130 is provided with an extension arm 140 extending outward.

[0040] In a specific embodiment, an extension arm 140 is set at the edge of the first lamp housing side 120; when the linear light is installed in a cabinet, the second lamp housing side 130 is close to the inner wall of the cabinet, and the extension arm 140 at the edge of the first lamp housing side 120 is mounted on the horizontal partition in the cabinet to complete the placement of the linear light.

[0041] In another specific embodiment, an extension arm 140 is provided at the edge of the second lamp housing side 130; when the linear light is installed in a cabinet, the first lamp housing side 120 is close to the inner wall of the cabinet, and the extension arm 140 at the edge of the second lamp housing side 130 is mounted on the horizontal partition in the cabinet to complete the placement of the linear light.

[0042] In another specific embodiment, extension arms 140 are provided on the edges of the first lamp housing side 120 and the second lamp housing side 140; when the linear light is installed in a cabinet, corresponding grooves need to be provided on the horizontal partitions in the cabinet, and the first lamp housing side 120 and the second lamp housing side 130 are inserted into the grooves, and the two extension arms 140 are mounted on the two side edges of the grooves to complete the placement of the linear light.

[0043] In this application, please refer to the attached Figure 4 and attached Figure 5 The power connection end 400 includes an end cover 410, an insert plate 420, a conductive terminal 460 and a wire 470. The insert plate 420 is arranged at one end of the end cover 410 and inserted into the lamp housing 100. Two conductive terminals 460 are arranged, which are respectively located on the lower side of the insert plate 420 and contact with the two conductive layers 230. One end of the conductive terminal 460 passes through the end cover 410 and is connected to the wire 470.

[0044] Specifically, in order to connect the conductive layer 230 pasted on the two sides of the lamp housing to the electricity, the two conductive terminals 460 are extended laterally. Therefore, during installation, the plug-in board 420 is directly inserted between the first lamp housing side 120 and the second lamp housing side 130 to make it fit tightly. The two conductive terminals 460 contact the two conductive layers 230, and the end cover 410 contacts the end of the first lamp housing side 120 and the end of the second lamp housing side 130, ensuring that the lampshade 300 is blocked by the power connection terminals 400 at both ends of the lamp housing 100, thereby completing the assembly of the linear lamp.

[0045] It should be noted that only the wire 470 in one of the power terminals 400 needs to be connected to the power supply. If the wires 470 of both power terminals 400 are connected to the power supply, the light strip 200 will be short-circuited. It can be understood that the two wires 470 on one of the power terminals 400 are connected to each other, and the two wires 470 on the other power terminal 400 are respectively connected to the positive and negative poles of the power supply, so that a complete electrical circuit is formed between the light strip 200 and the power supply. Alternatively, it can be understood that the two conductive terminals 460 on one of the power terminals 400 are connected to each other at the ends away from the conductive layer 230, and the two conductive terminals 460 on the other power terminal 400 are respectively connected to the two wires 470, thereby eliminating the use of a group of wires 470 and further saving space.

[0046] Furthermore, in order to make the power terminal 400 more smoothly inserted into the lamp housing 100, a slide groove 150 is respectively set on the first lamp housing side 120 and the second lamp housing side 130, and the two sides of the plug plate 420 are respectively inserted into the slide groove 150. When the power terminal 400 is assembled with the lamp housing 100, the plug plate 420 slides along the slide groove 150.

[0047] In order to separate the two conductive terminals 460, a middle partition 430 is provided at one end of the end cover 410 and in the middle position of the lower side of the plug plate 420, and the two conductive terminals 460 are respectively arranged on both sides of the middle partition 430; specifically, the middle partition 430 is wide in the middle and narrow at both ends, so the conductive terminals 460 are in contact with the conductive layer 230 at the wider part of the middle partition 430, so that the middle partition 430 not only has the effect of separating the conductive terminals 460, but also has the effect of stabilizing the electrical connection.

[0048] In order to further limit the installation position of the conductive terminal 460 and prevent the conductive terminal 460 from being misplaced during installation, a side partition 440 is provided on the outer side of the middle partition 430, so that a partition gap 450 is formed between the middle partition 430 and the side partition 440, and the conductive terminal 460 is inserted into the partition gap 450; specifically, side partitions 440 are respectively provided at the four corners of the bottom of the plug plate 420, and the front and rear sides of the conductive terminal 460 are respectively retracted inward, so that the conductive terminal 460 has a tendency to expand outward in the middle of the middle partition 430, so that the tightness of the contact between the conductive terminal 460 and the conductive layer 230 can be further improved when the power terminal 400 is inserted into the lamp housing 100.

[0049] In summary, the double-side powered linear lamp of the present application shortens the width requirement of the bottom edge of the lamp housing, reduces the width of the lamp housing, and is suitable for narrow installation spaces.

[0050] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
