[0039] The existing ceiling linear lights have the problem that after installation, the illumination angle cannot be flexibly adjusted according to specific lighting needs, and cannot meet diverse lighting requirements, which affects the overall lighting quality and atmosphere creation.

[0040] In response to the above problems, the present application makes improvements and innovations and proposes the following embodiments.

[0041] In one embodiment, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 , provides a ceiling linear lamp with adjustable illumination angle, comprising at least one lamp body 200 and at least two lamp holders 100 for hanging the lamp body 200 on a mounting base, wherein the installation angle of the lamp body 200 on the lamp holder 100 is adjustable; wherein, the lamp holder 100 comprises a substrate 1, a lamp holder 2, and a hanger 3, the interior of the substrate 1 is hollow and two elastic pressure blocks 11 are symmetrically arranged on the left and right, the lamp holder 2 is a hollow cylindrical structure with openings at both ends and the bottom, the front and rear ends of the lamp holder 2 are respectively suspended below the substrate 1 by a hanger 3, and a plurality of positioning grooves 21 that can match the elastic pressure blocks 11 are constructed on the outer wall of the lamp holder 2 along the extension direction of the lamp holder 2, the installation angle of the lamp holder 2 relative to the substrate 1 can be rotatably adjusted by the cooperation of the positioning grooves 21 and the two elastic pressure blocks 11, and the lamp body 200 can be detachably fixed on the lamp holder 2.

[0042] In this way, by respectively arranging matching elastic pressing blocks 11 and positioning grooves 21 on the substrate 1 of the lamp holder 100 and the lamp frame 2, and clamping the lamp body 200 on the lamp frame 2, the installation angle of the lamp frame 2 relative to the substrate 1 can be rotated and adjusted by the cooperation of the positioning grooves 21 and the two elastic pressing blocks 11, so that the lamp body 200 can be driven to rotate by the lamp frame 2 to realize the adjustment of the installation angle of the lamp body 200 on the lamp holder 100, thereby realizing the flexible adjustment of the illumination angle of the lamp body 200. In actual application, after the ceiling linear lamp is installed on a mounting base such as a ceiling or a wall, the installation angle of the lamp body 200 on the lamp holder 100 can also be adjusted by rotating the lamp frame 2, so that the user can flexibly adjust the illumination angle of the lamp body 200 according to specific lighting needs, which can meet diverse lighting requirements and is conducive to improving the overall lighting quality and improving the atmosphere creation.

[0043] In some embodiments, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The inner walls of the front and rear ends of the lamp holder 2 are radially protruding with reinforcing ribs 22, and the inner side of the lower end of the reinforcing rib 22 is horizontally protruding inward with a first clip 23 for clamping the lamp body 200, so that the lamp body 200 can be detachably fixed on the lamp holder 2 through the cooperation of the first clip 23 and the slot 41 constructed on the aluminum profile shell 4.

[0044] In this embodiment, a hanging portion 24 is extended outward at the front and rear ends of the lamp holder 2 at the outer ends of the reinforcing ribs 22, and two hangers 3 are formed with a supporting portion 31 facing the side of the lamp holder 2. The curvature of the upper side surface of the supporting portion 31 matches the curvature of the inner wall surface of the hanging portion 24, so that the lamp holder 2 can be hung under the substrate 1 by lifting the hanging portion 24 of the lamp holder 2 through the supporting portions 31 of the two hangers 3; specifically, the supporting portion 31 does not press the hanging portion 24 and the substrate 1 tightly. When the lamp holder 2 is rotated to a certain angle, the two elastic pressing blocks 11 on the substrate 1 press the lamp holder 2 down in the positioning groove 21 under the action of elasticity, so that the hanging portion 24 of the lamp holder 2 is pressed toward the supporting portion 31, thereby achieving the fixation of the lamp holder 2 and locking of the installation angle of the lamp holder 2.

[0045] In some embodiments, see Figures 1-8 The lamp body 200 comprises an aluminum profile housing 4, an insulating lamp housing 5, a light source board 6, a power supply assembly 7, a front cover 8, a rear cover 9, and a diffuser 10. The light source board 6 comprises a PCB and a plurality of LED beads arrayed on the PCB. The aluminum profile housing 4 is a hollow tubular structure with openings at both ends and the bottom. The left and right sides of the outer wall of the aluminum profile housing 4 are horizontally recessed and formed with slots 41 extending through the aluminum profile housing 4. The aluminum profile housing 4 is removably fixed to the lamp holder 2 through the engagement of the slots 41 with the first clips 23, thereby achieving removable mounting of the lamp body 200 to the lamp holder 2. The insulating lamp shell 5 is inserted into the aluminum profile shell 4, the light source board 6 is inserted on the insulating lamp shell 5, the diffuser 10 is inserted on the aluminum profile shell 4 on one side of the irradiation direction of the light source board 6, the power supply assembly 7 is arranged above the light source board 6 and is electrically connected to the light source board 6, and the front and rear ends of the aluminum profile shell 4 are inserted with a front end cover 8 and a rear end cover 9 that can be connected end to end, and the front end cover 8 and the rear end cover 9 are electrically connected to the power supply assembly 7, so as to realize power supply to the light source board 6 to realize lighting through the LED lamp beads. Under the action of the diffuser 10, the light emitted by the LED lamp beads is evenly and softly emitted on the luminous surface of the diffuser 10.

[0046] In this embodiment, a shoulder 42 is constructed at the position of the inner wall of the aluminum profile housing 4 corresponding to the slot 41, and the insulating lamp housing 5 is inserted into the aluminum profile housing 4 through the shoulder 42. The inner side of the insulating lamp housing 5 is constructed with a first slot 51 that passes through the insulating lamp housing 5 along the extension direction of the aluminum profile housing 4, and the light source board 6 is inserted into the first slot 51; the inner side of the lower end of the aluminum profile housing 4 is constructed with a second slot 43 that passes through the aluminum profile housing 4 along the extension direction of the aluminum profile housing 4, and the diffuser 10 is inserted into the second slot 43. The lower end of the insulating lamp housing 5 is located on both sides of the lamp beads of the light source board 6 and is constructed with a reflector 52 with an opening facing the diffuser plate 10, and the lower end of the reflector 52 is inserted into the second slot 43 at a position above the diffuser plate 10. In this way, by inserting the insulating lamp shell 5 for inserting the light source board 6 into the aluminum profile shell 4, the aluminum profile shell 4 is an insulating material, so that the aluminum profile shell 4 can ensure that there is no electric shock when touching the lamp body 200; by forming a reflector 52 at the lower end of the insulating lamp shell 5, the light emitted by the LED lamp beads can fully reach the diffuser 10 through the reflector 52, thereby improving the lighting effect, and there is no need to install additional reflective elements, the structure is simple, and assembly is convenient.

[0047] In some embodiments, see Figure 1-Figure 3 、 Figure 5 、 Figure 6 The inner side of the aluminum profile shell 4 is constructed with a mounting groove 44 that passes through the aluminum profile shell 4 along the extension direction of the aluminum profile shell 4. The front end cover 8 and the rear end cover 9 are respectively installed on the front and rear ends of the aluminum profile shell 4 by screws; wherein, the front end cover 8 includes a front end cover body 81 and a female socket 82, the female socket 82 is detachably fixed and inserted on the front end cover body 81, and a card block 821 is constructed on the upper end of the female socket 82, and the rear end cover 9 includes a rear end cover body 91 and a male plug 92, the male plug 92 is detachably fixed and inserted on the rear end cover body 91, and a second card buckle 921 that matches the card block 821 is constructed on the upper end of the male plug 92. In this way, when multiple lamp bodies 200 need to be spliced ​​together for use, the male plug 92 on the rear end cover 9 of the previous lamp body 200 can be plugged into the female socket 82 on the front end cover 8 of the next lamp body 200, so that the two adjacent lamp bodies 200 can be spliced ​​end to end in sequence and electrically connected through the rear end cover 9 of the previous lamp body 200 and the front end cover 8 of the next lamp body 200.

[0048] In some embodiments, see Figure 1-Figure 3 、 Figure 5 、 Figure 6The length of the aluminum profile housing 4 is shorter than the length of the insulating lamp housing 5, and the length of the diffuser plate 10 is longer than the length of the insulating lamp housing 5. Specifically, when the front end cover 8 and the rear end cover 9 are installed on the aluminum profile housing 4, the front and rear end surfaces of the aluminum profile housing 4 respectively abut the end surfaces of the side walls of the front and rear end covers 8 and 9, and the front and rear end surfaces of the insulating lamp housing 5 respectively abut the inner end surfaces of the front and rear end covers 8 and 9. As a result, the front and rear end covers 8 and 9 can effectively block the front and rear ends of the lamp body, achieving dustproof and waterproof effects.

[0049] In this embodiment, when two adjacent lamp bodies 200 are spliced ​​end to end through the front end cover 8 and the rear end cover 9, the outer end face of the rear end cover 9 of the previous lamp body 200 contacts the outer end face of the front end cover 8 of the rear lamp body 200, and the rear end face of the diffuser plate 10 of the previous lamp body 200 is in close contact with the front end face of the diffuser plate 10 of the rear lamp body 200. Therefore, by virtue of the length of the diffuser plate 10 being longer than the length of the insulating lamp shell 5, when the two adjacent lamp bodies 200 are spliced ​​end to end through the front end cover 8 and the rear end cover 9, the diffuser plates 10 of the two adjacent lamp bodies 200 are seamlessly spliced, which can effectively avoid the formation of dark areas at the front and rear end covers of the lamp body 200, and further effectively ensure the continuity and integrity of the light emitted by the lamp body 200, so as to ensure the luminous quality and luminous effect of the lamp body 200.

[0050] In some embodiments, see Figure 1-Figure 3 、 Figure 7 、 Figure 8 The power supply assembly 7 includes a driving power supply 71, a dip switch 72, a first bracket 73, a second bracket 74, and a mounting plate 75. The first bracket 73 and the second bracket 74 are detachably fixed to the back of the light source board 6 by screws. A mounting plate 75 is installed between the first bracket 73 and the second bracket 74 by screws. The driving power supply 71 is fixedly mounted on the mounting plate 75. The second bracket 74 is a frame structure with an open bottom. The dip switch 72 is detachably fixed to the second bracket 74 by screws, and the driving power supply 71 and the dip switch 72 are spaced apart from the light source board 6. The dip switch 72 includes a switch body 721, a lever 722, a paddle 723, and a slide 724. The switch body 721 is mounted on the second bracket 74 by screws. A lever 722 is provided on the switch body 721. The paddle 723 is engaged with the lever 722. The slide 724 is slidably set on the outer wall of the aluminum profile housing 4 and is mounted on the paddle 723 by screws. Therefore, the mains power can be converted through the driving power supply 71 and stable voltage and current can be provided to the light source board 6 to ensure that the brightness of the LED lamp beads of the light source board 6 is uniform and stable, which is also beneficial to extending the service life of the LED lamp beads. The color temperature of the light emitted by the LED lamp beads of the light source board 6 can be adjusted through the dip switch 72 to facilitate adaptive adjustment according to lighting needs.

[0051] Compared with the method of directly installing the driving power supply 71 and the dial switch 72 on the back of the light source board 6 in the prior art, in this embodiment, the driving power supply 71, the dial switch 72 and the light source board 6 are spaced apart by setting a first bracket 73, a second bracket 74 and a mounting plate 75, so that the driving power supply 71 and the dial switch 72 are not in contact with the light source board 6. In this way, there is a certain space between the driving power supply 71, the dial switch 72 and the light source board 6, which can effectively avoid the heat generated when the light source board 6 emits light, causing the working performance of the driving power supply 71 and the dial switch 72 to deteriorate or shorten the life; at the same time, a detachable installation method is adopted between the driving power supply 71, the dial switch 72 and the light source board 6, which is convenient for maintenance and replacement of various components.

[0052] Finally, it should be noted that although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can make changes, modifications, replacements and variations to the above embodiments within the scope of the present invention, which should all be included in the scope of protection of this application.
