[0030] When multiple LED lights are assembled together, cascading them to create a linear lighting effect is a common practice. However, because the assembly structures of each LED light are relatively independent, even when multiple LED lights are installed in a collinear manner, some LED lights may inevitably deviate from the intended straight line, resulting in poor lighting effects.

[0031] To address the aforementioned problems, this application provides an LED lighting fixture, please refer to... Figures 1 to 3 As shown, the LED light fixture includes:

[0032] The housing assembly 1 includes a lamp housing 2 and a lamp shade 3 arranged opposite to each other. The lamp housing 2 and the lamp shade 3 are fixedly connected, and the lamp housing 2 and the lamp shade 3 enclose a receiving space. The lamp housing 2 has a first end 21 and a second end 22 arranged opposite to each other along the length direction. The first end 21 is provided with a first positioning member, and the second end 22 is provided with a second positioning member. The first positioning member and the second positioning member are located on the same straight line along the length direction. The first positioning member is used to cooperate with the second positioning member of the adjacent LED lamp when multiple LED lamps are connected in series to lock the relative position between the adjacent LED lamps. The first end 21 and the second end 22 are also each provided with a first connecting part 25 and a second connecting part 26. The first connecting part 25 is used to form a fixed connection with the first connecting part 25 of the adjacent LED lamp.

[0033] The light-emitting component is disposed in the accommodating space, and the light emitted by the light-emitting component is emitted outward through the lamp cover 3.

[0034] In the specific structure of the LED lamp, the housing assembly 1 has a lamp housing 2 and a lamp shade 3. The lamp housing 2 and the lamp shade 3 are arranged opposite to each other and fixedly connected. The lamp housing 2 and the lamp shade 3 enclose a receiving space. The receiving space is used to install other devices required for the operation of the LED lamp, including light source, controller, circuit, etc.

[0035] For LED lamps, the lamp housing 2 and lamp shade 3 correspond to the light-shielding and light-emitting parts, respectively. The lamp housing 2, as the light-shielding structure of the LED lamp, blocks the light emitted from the non-light-emitting side of the LED, preventing light leakage. The lamp shade 3, while enclosing and forming a housing space, allows light emitted from the light source located inside the lamp shade 3 to pass through and be emitted outwards. For this purpose, the lamp shade 3 is made of light-transmitting materials, including light-transmitting glass and light-transmitting plastic. Since the lamp housing 2 needs to block the light emission, it is usually an opaque structure. Specifically, the lamp housing 2 can be made of opaque materials, or it can be made by applying an opaque coating to a transparent material.

[0036] The lamp housing 2 and the lamp shade 3 can be fixedly connected by means of snap-fit, threaded connection or other methods. At least one of the lamp shade 3 and the lamp housing 2 has a recessed structure, which allows the lamp shade 3 and the lamp housing 2 to form the required accommodating space when they are fixedly connected.

[0037] To ensure that the positions of multiple LED lights are relatively fixed and do not shift when multiple LED lights are spliced ​​together, the lamp housing 2 in this embodiment has a first end 21 and a second end 22 arranged opposite each other along its length. Each of the first end 21 and the second end 22 is respectively provided with a first positioning member and a second positioning member, which cooperate with each other. When multiple LED lights are connected in series, the first and second positioning members of adjacent LED lights cooperate to lock the relative positions between adjacent LED lights. The first and second positioning members are located on the same straight line along the length direction. When they cooperate, adjacent LED lights also extend along the same straight line where the first and second positioning members meet, thereby achieving the purpose of setting the LED lights along a straight line.

[0038] After the LED lights achieve mutual locking with adjacent LED lights through the first and second positioning members, a fixed connection is further formed with the adjacent LED lights through the first connecting part 25 and the second connecting part 26. The first connecting part 25 and the second connecting part 26 can be integrally formed with the housing assembly 1, or detachably connected to the housing assembly 1. Their function is to solidify the positions of adjacent LED lights, preventing subsequent separation of their positions. While the relative positions of the LED lights are fixed, the connection can be released by disassembling the connection between the first connecting part 25 and the second connecting part 26. In this embodiment, the first connecting part 25 and the second connecting part 26 can be directly connected, or a fixed connection can be formed indirectly through other components.

[0039] In some optional embodiments, to facilitate fixing the position between adjacent LED lights, the first positioning member and the second positioning member may each include at least one pair of protrusions 27 and grooves 28. The protrusions 27 extend outward along the length direction, and the grooves 28 are recessed inward along the length direction, with the protrusions 27 and grooves 28 arranged collinearly along the length direction. The protrusions 27 and grooves 28 are arranged opposite to each other, and the protrusions 27 can lock the relative position between adjacent LED lights by being inserted into the grooves 28. The opening of the groove 28 faces the extending direction of the protrusions 27 on the adjacent LED lights, and the shapes of the protrusions 27 and grooves 28 match each other. Provided that the protrusions 27 are inserted into the grooves 28, the protrusions 27 and grooves 28 can be set to different shapes.

[0040] The first positioning element and the second positioning element each include at least one set of paired protrusions 27 and grooves 28. This means that the first positioning element can have one set of protrusions 27 and the second positioning element can have a corresponding set of grooves 28, or the first positioning element can have two or more sets of protrusions 27 and the corresponding second positioning element can have two or more sets of grooves 28. Alternatively, the first positioning element can have at least one set of protrusions 27 and at least one set of grooves 28, meaning the protrusions 27 and grooves 28 are arranged in parallel, and the corresponding second positioning element can also have at least one set of grooves 28 and at least one set of protrusions 27. In other words, the number and position of the grooves 28 and protrusions 27 in the embodiments of this application can be arbitrary, as long as the grooves 28 and protrusions 27 are paired on the first and second positioning elements.

[0041] In some optional embodiments, to improve the positioning effect and prevent adjacent LED lights from misaligning, the first positioning element may specifically include at least two adjacent protrusions 27, and the second positioning element may include at least two adjacent grooves 28. When the first positioning element is provided with at least two protrusions 27 and the second positioning element is provided with at least two corresponding grooves 28, the cooperation between the grooves 28 and the protrusions 27 can not only lock the position of adjacent LED lights in the length direction, but also prevent adjacent LED lights from shifting in the direction perpendicular to the length direction; the more combinations of protrusions 27 and grooves 28 are provided, the higher the requirement for processing precision, and the better the effect of preventing shifting.

[0042] In some optional embodiments, the first positioning member may further include at least one protrusion 27 and at least one groove 28 arranged adjacently, and the second positioning member includes at least one groove 28 and at least one protrusion 27 arranged adjacently. In other words, the first positioning member can arrange the groove 28 and the protrusion 27 in parallel, and the second positioning member correspondingly arranges the protrusion 27 and the groove 28 in parallel. With this structure, the LED lamp can still be assembled with adjacent LED lamps even when rotated 180°. In addition, to prevent assembly misalignment, each protrusion 27 and each groove 28 is centrally symmetrically distributed about the geometric center of the LED lamp. Since the protrusion 27 and the groove 28 are centrally symmetrically distributed, after the LED lamp is rotated 180°, each protrusion 27 and groove 28 is still in its corresponding position, which facilitates the assembly of the LED lamp and allows positioning to be completed without confirming the specific direction.

[0043] In some alternative embodiments, please refer to Figure 4 and Figure 5 To connect the first connecting portion 25 and the second connecting portion 26, a connecting plate 5 may be included. The connecting plate 5 spans across adjacent LED light fixtures and is connected to both the first connecting portion 25 and the second connecting portion 26. The connecting plate 5 is detachably connected to both the first connecting portion 25 and the second connecting portion 26. To ensure the stability of the structure after connection, the connecting plate 5 is typically made of a rigid material.

[0044] In some optional embodiments, to achieve the connection between the connecting plate 5 and the first connecting portion 25 and the second connecting portion 26, the first connecting portion 25 and the second connecting portion 26 may be provided with a plurality of first mounting holes 29, and the connecting plate 5 may be provided with a plurality of second mounting holes 51, the second mounting holes 51 being arranged opposite to the first mounting holes 29; it also includes a plurality of connectors 52, the connectors 52 being sequentially inserted into the second mounting holes 51 and the first mounting holes 29, so that the connecting plate 5 is fixedly connected to the first connecting portion 25 and the second connecting portion 26 respectively. By inserting the connectors 52 into the first mounting holes 29 and the second mounting holes 51, the relative positions between the first connecting portion 25, the second connecting portion 26 and the connecting plate 5 can be locked. When the relative positions are locked, the connecting plate 5 and the first connecting portion 25 and the second connecting portion 26 are equivalent to forming a fixed connection. Specifically, the first mounting hole 29 and the second mounting hole 51 can be threaded holes with internal threads, and the connecting piece 52 can be a threaded fastener with corresponding external threads. The threaded fastener can be a stud, screw, etc., and can also be used with a washer or nut to form a fixed connection.

[0045] In some optional embodiments, in order to further fix the relative positions between adjacent LED lamps while connecting them, the first connecting portion 25 may further include at least one first mounting groove 251, which extends along the length direction and whose opening communicates with the surface of the first end 21; the second connecting portion 26 includes at least one second mounting groove 261, which extends along the length direction and whose opening communicates with the surface of the second end 22, and is collinear with the first mounting groove 251; the first mounting groove 251 and the second mounting groove 261 of the adjacent LED lamps together form an assembly space, and the connecting plate 5 is disposed in the assembly space. In other words, in the embodiments of this application, the first connecting portion 25 and the second connecting portion 26 are each an open receiving groove that can be used to receive the connecting plate 5. Therefore, the two sides of the connecting plate 5 are limited by the side walls of the receiving groove, which further restricts the connecting plate 5 from shifting in a direction perpendicular to the length direction, thereby further ensuring the assembly state when the LED lamps are connected to each other.

[0046] In some alternative embodiments, to maximize the limitation of mutual offset between LED lamps, the widths of the first mounting slot 251 and the second mounting slot 261 can be configured to match the dimensions of the connecting plate 5 in the corresponding direction. Here, "matching dimensions" means that the dimensions of the first mounting slot 251 and the second mounting slot 261 in the corresponding direction are similar to those of the connecting plate 5. For ease of assembly, the dimensions of the connecting plate 5 can be set to be slightly smaller than the corresponding dimensions of the first mounting slot 251 and the second mounting slot 261. Furthermore, the shapes of the first mounting slot 251 and the second mounting slot 261 can also be adapted to the connecting plate 5.

[0047] In some optional embodiments, the first connecting portion 25 may specifically include two or more first mounting slots 251, each first mounting slot 251 being arranged side by side along the length direction; the second connecting portion 26 includes two or more second mounting slots 261, each second mounting slot 261 being arranged side by side along the length direction. The multiple mounting slots can accommodate multiple connecting plates 5, or the multiple connecting plates 5 can be arranged across multiple mounting slots.

[0048] According to the LED lamp provided in the embodiments of this application, since the first positioning member and the second positioning member are respectively provided at both ends of the lamp housing 2 in the length direction, the relative positions between adjacent LED lamps are locked, so that the LED lamps can be arranged collinearly along the length direction, avoiding the LED lamp installation position from deviating and improving the lighting effect.

[0049] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the concept of this invention.
