[0035] The lamp housing 1 is provided with a mounting plate 11, and the light source 7 is an LED light source plate. The light source 7 is fixedly mounted on a front face of the mounting plate 11 through screws.

[0036] Two opposite inner side faces of the light outlet opening are inwardly provided with receiving edges 13, and side portions of the light outlet 8 facing the receiving edges 13 are provided with side portion light outlet edges 81, and the side portion light outlet edges 81 are received on the receiving edges 13.

[0037] The light outlet 8 can be connected and fixed with the mounting plate 11 through screws, or connected with the lamp housing 1 through a buckle connection structure. The light outlet 8 is a light-transmitting plate or a grid lens.Figure 1 , 3 As shown, the light-emitting element 8 is a grid lens.

[0038] In another preferred embodiment, such as Figure 4 , 5 As shown in Figure 6, the light-emitting component 8 is a light-transmitting plate. Hooks 801 are provided on both sides of the light-transmitting plate along its length. The receiving edge is located above the hooks 801. Grooves 12 that are adapted to the hooks 801 are provided on both sides of the lamp housing 1 along its length.

[0041] The track connection structure 30 includes a base portion 4, cantilever hooks 41 located on both sides of the base portion 4 for snap-fit ​​connection with the track 20, a bottom cover 3 covering the base portion 4, a push-button latch 6 located below the bottom cover 3, a latch head 52, and a movably mounted latch control button 5. The bottom cover 3 and the base portion 4 are connected by a snap-fit ​​structure to form a mounting shell, and are connected to the back of the mounting plate 11 by screws. Mounting openings 15 for mounting the bottom cover 3 are provided at both ends of the back of the lamp housing 1. The bottom cover 3 is located in the mounting openings 15 and is integrated with the lamp housing 1.

[0042] The bottom cover 3 and the base part 4 are spaced apart to form an installation cavity with an outer opening. The snap-on control button 5 is inserted into the installation cavity through the opening, and the pressing end of the snap-on control button 5 is exposed from the opening.

[0043] The two sides of the pressing part of the snap-on control button 5 are arc-shaped, and the two inner sides of the outer opening of the mounting cavity are arc-shaped to match the arc surface, facilitating the sliding of the snap-on control button 5. A guide block 53 is also provided on the outer side of the arc surface, and a guide groove is provided on the side of the mounting cavity, with the guide block 53 located in the guide groove. When the snap-on control button 5 is pressed inward or popped outward, the guide block 53 moves within the guide groove, limiting the movement path of the snap-on control button 5 and preventing it from detaching from the mounting cavity.

[0044] The latch head 52 and the push-type latch 6 are matched to form a push-type elastic self-locking mechanism. That is, when the latch head 52 is pressed into the push-type latch 6 once, the push-type latch 6 and the latch head 52 are locked together. When the latch head 52 is pressed again, the push-type latch 6 pops the latch head 52 out and the latch head 52 is disengaged from the push-type latch 6. The push-type elastic self-locking mechanism is existing technology, and its specific structure will not be described in detail.

[0046] The bottom cover 3 has a latching through hole 31 and a limiting hole 32 including a latching locking position and a latching unlocking position. The limiting hole 32 is located behind the latching through hole 31, and the latching locking position communicates with the latching through hole 31. The hook part of the cantilever hook 41 extends from the latching through hole 31, and the limiting part 51 extends from the limiting hole 32, moving within the limiting hole 32. Pressing the latching control button 5 once pushes the latching head 52 into the push-button latch 6, and the limiting part 51 moves to the latching locking position (e.g., ...). Figure 7 (As shown) – that is, the back of the cantilever hook 41, which abuts against the cantilever hook 41, and the locking head 52 and the push-type locking buckle 6 cooperate to position the buckle control button 5, thereby positioning the limiting part 51 in the locking position on the buckle. The limiting part 51 abuts against the cantilever hook 41, preventing the cantilever hook 41 from being pressed inward, keeping it in the position connected to the rail buckle, and the engagement is secure. Pressing the buckle control button 5 again, the push-type locking buckle 6 pops out the locking head 52, causing the buckle control button 5 to pop out and reset, and the limiting part 51 moves to the buckle unlock position (as shown). Figure 8 (As shown) - that is, the position behind the cantilever hook 41, which provides space for the cantilever hook 41 to spring inward so as to remove the lamp structure from the track.

[0047] When the limiting part 51 is positioned in the locking position on the buckle, the buckle control button 5 does not protrude from the end faces of both ends of the lamp structure.

[0048] Two locking heads 52 are provided, with one-to-one correspondence between the push-button locking heads 6 and the locking heads 52. Both locking heads 52 are integrally formed on the snap-on control button 5. The snap-on control button 5 includes extensions extending rearward from both sides of the push-button portion, with a limiting portion 51 located on the extensions. The locking heads 52 are located within the space between the two extensions. For a snap-on control button 5 with a certain width, providing two locking heads to cooperate with two push-button locking heads increases the self-locking force and makes the force on the snap-on control button 5 more balanced.

[0049] The second cantilever hook 33 is arranged on the bottom cover 3, and the second clamping groove 44 is arranged on the base portion 4, the second cantilever hook 33 is buckled into the second clamping groove 44, and the second cantilever hook 33 is clamped with the clamping plate in the second clamping groove 44, so that the bottom cover 3 is connected with the base portion 4. The second clamping groove 44 and the cantilever hook 41 are left with a space for the limiting portion 51 to pass through.

[0050] The bottom cover 3 is further provided with a supporting wall on both sides, and the supporting wall is supported on the back of the mounting plate 11.

[0051] The bottom cover 3 is further provided with a conducting sheet insertion hole, the conducting sheet 14 is fixed in the mounting shell and extends out of the conducting sheet insertion hole. The bottom cover 3 is further provided with a magnet 9 for adsorbing the iron strip on the track.

[0052] The base portion 4 is perpendicular to the end cover portion 41, and the base portion 4 is integrally formed with the end cover portion 41, so that the fixation of the end cover portion 41 is completed when the base portion 4 is connected and fixed.
