[0001] The utility model relates to a strip light, in particular to a one-sided power-connected strip light. Background Art

[0002] At present, with the continuous progress of lighting technology and the increasing requirements for energy conservation and environmental protection, LED lighting technology has been widely used due to its high efficiency, energy conservation, and environmental protection characteristics. As a common LED lighting product, LED strip lights are widely used in many fields such as indoor lighting and decorative lighting due to their soft, bendable, and easy-to-install characteristics.

[0003] In the existing strip lights, the conductive layers are distributed on both sides of the LED lamp beads. In this way, the width of the lamp housing will increase due to the occupation of the conductive layers, and it will be difficult to install the strip light in a relatively narrow installation space. Summary of the Invention

[0004] Aiming at the deficiencies in the prior art, the utility model provides a one-sided power-connected strip light, which improves the cooperation mode between the strip light and the lamp housing, transfers the conductive layer from the bottom edge of the lamp housing to the side edge of the lamp housing, and cooperates with the one-sided power connection of the power connection end to effectively reduce the width of the lamp housing without increasing the height of the lamp housing, making it more suitable for narrow spaces. The technical solution adopted by the utility model is as follows:

Detailed implementation manners

[0027] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0028] Please refer to the attached Figures 1-3 The present utility model provides a single - side power - connected linear lamp, which includes a lamp housing 100, a light strip 200, a lamp cover 300, and a power connection terminal 400. The lamp housing 100 includes a bottom edge 110 of the lamp housing, a first side 120 of the lamp housing connected to one side of the bottom edge 110 of the lamp housing, and a second side 130 of the lamp housing connected to the other side of the bottom edge 110 of the lamp housing; the light strip 200 includes a flexible printed circuit board 210, a plurality of LED lamp beads 220, and two conductive layers 230. The surface of the flexible printed circuit board 210 is divided into a first sub - surface and a second sub - surface. A plurality of the LED lamp beads 220 are longitudinally arranged at intervals on the first sub - surface, and the two conductive layers 230 are transversely arranged at intervals on the second sub - surface. Any one of the conductive layers 230 extends longitudinally; the first sub - surface is longitudinally laid on the bottom edge 110 of the lamp housing, and the second sub - surface is longitudinally laid on the second side 120 of the lamp housing; the lamp cover 300 is connected between the first side 120 and the second side 130 of the lamp housing; the power connection terminal 400 is inserted into the end of the lamp housing 100 and is electrically connected to the conductive layer 230.

[0029] In the light strip 200, the flexible printed circuit board 210 mainly uses polyimide or polyester film as the substrate. These materials have excellent flexibility and high - temperature resistance, enabling the flexible printed circuit board 210 to be bent inside the lamp housing 100. The conductive layer 230 on the flexible printed circuit board 210 usually uses copper foil, and its thickness can be adjusted according to needs, usually between several micrometers and dozens of micrometers.

[0030] It can be understood that, by utilizing the flexibility of the flexible circuit board 210, the surface of the flexible circuit board 210 is divided into a connected first sub-surface and a second sub-surface, merely for the purpose of distinguishing the arrangement positions of the conductive layer 230 and the LED lamp beads 220, and it does not mean that the first sub-surface and the second sub-surface are used as independent components. In fact, the flexible circuit board 210 still remains as a whole and can be bent and cut to adapt to lamp housings 100 of different lengths and shapes.

[0031] In this application, the copper foil is arranged on the second sub-surface of the flexible circuit board 210, and the first sub-surface loaded with the conductive layer 230 is pasted on the bottom edge 110 of the lamp housing. The two conductive layers 230 are transferred from the bottom of the lamp housing 100 to the side of the lamp housing 100, and then the end of the lamp housing 100 is blocked by the power connection terminal 400 while being electrically connected to the conductive layer 230, achieving power-on 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 as to be applicable to narrow installation spaces.

[0032] Specifically, a power connection terminal 400 is provided at each end of the lamp housing 100, and one of the power connection terminals 400 is connected to the power supply, forming a complete circuit between the lamp strip 200 and the power supply to achieve the lighting of the lamp strip 200.

[0033] Please refer to the append Figure 3 and append Figure 4 , a first notch 121 is provided on the first lamp housing side edge 120, a second notch 131 is provided on the second lamp housing side edge 130, and both sides of the lamp cover 300 are respectively inserted into the first notch 121 and the second notch 131.

[0034] In this application, the lamp cover 300 is in the shape of a strip board, and the light emitted by the LED lamp beads 220 on the lamp strip 200 passes through the lamp cover 300 to form light to illuminate the space to be illuminated; a channel for accommodating the lamp cover 300 is formed through the first notch 121 and the second notch 131, enabling the lamp cover 300 to be disassembled and assembled in a pulling manner from either end of the lamp housing 100, and cooperating with the power connection terminal 400 at the end of the lamp housing 100 to achieve the blocking of the lamp cover 300, so that no fixing parts such as bolts are required. It is not only convenient and fast to install and disassemble without drilling holes, but also ensures the structural strength of the linear lamp.

[0035] In a specific embodiment, the first notch 121 and the second notch 131 are not of the same height. When the first notch 121 and the second notch 131 are not of the same height, it means that the lamp cover 300 is arranged at an angle with the bottom edge 110 of the lamp housing during installation, and the lamp cover 300 refracts the light emitted by the LED lamp beads, avoiding glare when looking directly at the linear lamp. In order to further avoid increasing the height of the lamp housing 100, when the lamp cover 300 is arranged obliquely, the higher side of the lamp cover 300 corresponds to the first lamp housing side edge 120, and the lower side of the lamp cover 300 corresponds to the second lamp housing side edge.

[0036] It is understandable that the shapes of the first lamp housing side 120 and the second lamp housing side 130 are substantially the same and the heights are the same.

[0037] In order to facilitate the mounting and clamping of the lamp housing 100 to the required mounting position, the edge of the first lamp housing side 120 and / or the edge of the second lamp housing side 130 are extended outwardly to be provided with extension arms 140.

[0038] In a specific embodiment, the edge of the first lamp housing side 120 is provided with an extension arm 140; when the linear lamp is installed in the cabinet, the second lamp housing side 130 is closely attached 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 lamp.

[0039] In another specific embodiment, the edge of the second lamp housing side 130 is provided with an extension arm 140; when the linear lamp is installed in the cabinet, the first lamp housing side 120 is closely attached 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 lamp.

[0040] In still another specific embodiment, the edges of both the first lamp housing side 120 and the second lamp housing side 140 are provided with extension arms 140; when the linear lamp is installed in the cabinet, corresponding grooves need to be provided on the horizontal partition in the cabinet, 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 groove to complete the placement of the linear lamp.

[0041] In the present application, please refer to the attached Figure 4 and the attached Figure 5 , the power connection terminal 400 includes an end cover 410, an insertion block 420, a conductive terminal 430 and a wire 440. The insertion block 420 is disposed at one end of the end cover 410 and inserted into the lamp housing 100. There are two conductive terminals 430 and two wires 440 respectively. The two conductive terminals 430 are respectively located on the side of the insertion block 420 and contact the two conductive layers 230. One end of the conductive terminal 430 passes through the insertion block 420 and is connected to the wire 470.

[0042] In order to cooperate with the power connection of the conductive layer 230 pasted on the second lamp housing side 130, the two conductive terminals 430 are arranged on the same side of the insertion block 420. During installation, the insertion block 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 430 contact the two conductive layers 230, and the end cover 410 contacts the ends of the first lamp housing side 120 and the second lamp housing side 130 to ensure that the lamp cover 300 is blocked by the power connection terminals 400 at both ends of the lamp housing 100 to complete the assembly of the linear lamp.

[0043] It should be noted that only the wires 440 in one of the power terminals 400 need to be connected to the power supply. If the wires 440 of both power terminals 400 are connected to the power supply, the light strip 200 will be short-circuited. In a specific embodiment, the two wires 440 on one of the power terminals 400 are connected to each other, and the two wires 440 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. In another specific embodiment, the two conductive terminals 430 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 430 on the other power terminal 400 are respectively connected to the two wires 440, thereby eliminating the use of a group of wires 440 and further saving space.

[0044] In order to prevent the power terminal 400 from being reversely inserted at both ends of the lamp housing 100, a convex strip 150 is protrudingly provided on the inner side of the second lamp housing side 130, and a step 421 matching the convex strip 150 is correspondingly provided on the side of the plug block 420. For example, when the power terminal 400 corresponding to the front end of the lamp housing 100 is inserted into the rear end of the lamp housing 100, since there is no convex strip 150 on the first lamp housing side 130 and no step 421 on the other side of the power terminal, the movement of the plug block 420 will be hindered, and vice versa. This structural design can prevent the power terminal 400 from being reversely inserted and prevent the positive and negative poles of the flexible circuit board 210 from being reversely connected.

[0045] In order to avoid interference between the plug block 420 and the obliquely inserted lampshade 300, and to prevent the electrical terminal 400 from being reversely plugged in, a slope 422 that matches the lampshade 300 is provided on the top of the plug block 420; it is worth noting that when the slope on the plug block 420 contacts the lampshade 300, it can also provide tension to the surface of the lampshade 300, thereby supporting the lampshade 300. In practice, the lampshade 300 is restricted by the first notch 121, the second notch 131, the slope 412 and the end cover 410, and is stably fixed on the lamp housing 100.

[0046] In summary, the single-sided power-connected linear lamp of the present application, with a single-sided conductive power connection terminal and an inclined lampshade, shortens the width requirement of the bottom edge of the lamp housing without increasing the height of the lamp housing, reduces the width of the lamp housing, and is suitable for narrow installation spaces.

[0047] 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.
