DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the schemes in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. In addition, the descriptions of "first", "second", etc. in the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

[0032] In view of the technical defects in the related art, this utility model provides a lamp with adjustable light output angle. Figures 1 to 5 The lamp with adjustable light output angle includes: a shell 100, a lamp board 200 and a lens 300; wherein, the shell 100 serves as a load-bearing structural member for various components of the lamp, and can be made of plastic or metal. In this embodiment, in order to ensure the heat dissipation effect of the lamp board 200 installed in the shell 100, the shell 100 is made of a metal material with good thermal conductivity, such as aluminum alloy.

[0033] Furthermore, the shell 100 has a mounting groove 110 with an open end; the mounting groove 110 can be set as a square groove or a circular groove. The mounting groove 110 can be set according to the outer contour shape of the shell 100, so that the overall appearance of the shell 100 is relatively simple.

[0034] The lamp board 200 is installed in the installation groove 110. There are multiple lamp beads 210 on the lamp board 200. It should be noted that the lamp board 200 is installed in the installation groove 110 using a detachable installation method, such as screw locking, snap connection, etc., to facilitate subsequent disassembly and replacement.

[0035] In addition, the lens 300 can be rotatably installed in the mounting groove 110 and cover the light board 200. There are many ways to rotatably install the lens 300 in the mounting groove 110. For example, a rotating boss is provided at the rotation center of the lens 300, and a rotating groove is provided on the shell 100 corresponding to the rotating boss, and the rotating boss is rotatably connected to the rotating groove; for another example, the lens 300 is provided with a circular shape, and the mounting groove 110 is also circular in shape. The lens 300 and the mounting groove 110 are clearance-matched so that the lens 300 can rotate in the mounting groove 110; how the lens 300 is specifically rotatably installed in the mounting groove 110 is not specifically limited here.

[0036] Furthermore, the lens 300 has a first light-transmitting area 310 and a second light-transmitting area 320 with different light-emitting angles. The first light-transmitting area 310 and the second light-transmitting area 320 are adjacent to each other along the rotational direction of the lens 300, and the lens 300 has a first rotation position and a second rotation position due to the rotation; in this way, when the lens 300 rotates, when the lens 300 is in the first rotation position, the first light-transmitting area 310 covers multiple lamp beads 210; and when the lens 300 is in the second rotation position, the second light-transmitting area 320 covers multiple lamp beads 210.

[0037] In addition, the first light-transmitting area 310 and the second light-transmitting area 320 can be set to different light-emitting angles according to user needs. For example, the first light-transmitting area 310 can be set to a larger light-emitting angle, such as 110°, 120°, etc. The large light-emitting angle is suitable for scenes that need to illuminate a large area, such as a living room, corridor, etc., while the second light-transmitting area 320 can be set to a smaller light-emitting angle, such as 60°, 50°, etc. The small light-emitting angle is suitable for scenes that need to emphasize the shape and texture of objects, as well as occasions that require strong light and dark contrast, such as exhibits, counter products, etc. With this setting, the lamp with adjustable light-emitting angle can be suitable for use scenarios with different light-emitting angle requirements. Without replacing the lens 300, different light-transmitting areas can be adjusted by rotating the lens 300 to obtain different light-emitting angles, which is convenient to use.

[0038] Through the above technical solution, the lens 300 of the lamp with adjustable light output angle is rotatably mounted on the shell 100, and the lens 300 is provided with a first light-transmitting area 310 and a second light-transmitting area 320 with different light-output angles, so that after rotation, the first light-transmitting area 310 of the lens 300 covers the first rotation position of the lamp bead 210 and the second light-transmitting area 320 covers the second rotation position of the lamp bead 210; with such a setting, the user can rotate the lens 300 according to needs to adjust the corresponding light-transmitting areas on different lenses 300 to obtain different light-output angles, thereby enabling the lamp to adapt to different lighting usage scenarios and improving the versatility of the lamp.

[0039] In order to make the light of the lamp with adjustable light output angle brighter and more uniform, in some embodiments, the lamp beads 210 of the lamp board 200 are arranged in a circular shape, and each lamp bead (210) is arranged at intervals along the center of the lamp board 200 toward the outside of the lamp board 200, and a plurality of first light-transmitting areas 310 and second light-transmitting areas 320 are provided. Each first light-transmitting area 310 and each second light-transmitting area 320 are arc-shaped and connected end to end to form a plurality of annular light-transmitting bodies of different diameters, and each annular light-transmitting body is coaxially arranged with the rotation center of the lens 300.

[0040] Furthermore, the first light-transmitting areas 310 and the second light-transmitting areas 320 on two adjacent annular light-transmitting bodies are staggered.

[0041] With such a configuration, the lamp beads 210 on the lamp board 200 can be designed to be more numerous and evenly distributed. When the lens 300 is rotated to the first rotation position, each first light-transmitting area 310 can respectively cover each lamp bead 210 on the lamp board 200, while each second light-transmitting area 320 is located in a blank area of ​​the lamp board where no lamp bead 210 is provided, so that in the first rotation position, only the first light-transmitting area 310 covers the lamp bead 210, while the second light-transmitting area 320 between two adjacent first light-transmitting areas 310 does not cover the lamp bead 210; Similarly, when the lens 300 is rotated to the second rotation position, each second light-transmitting area 320 can respectively cover each lamp bead 210 on the lamp board 200, while each first light-transmitting area 310 is located in the blank area of ​​the lamp board where no lamp bead 210 is provided, so that in the second rotation position, only the second light-transmitting area 320 covers the lamp bead 210, and the first light-transmitting area 310 between two adjacent second light-transmitting areas 320 does not cover the lamp bead 210; in this way, the lens 300 can adjust the overall light output angle of the lamp by rotating.

[0042] In order to ensure that the lens 300 can be positioned when it is rotated to the first rotation position or the second rotation position, in this embodiment, the lamp with adjustable light output angle further includes a limiter 400, which is connected to the housing 100 to limit the rotation of the lens 300. The limiter 400 can limit the lens 300 in a variety of ways. For example, the limiter 400 is set on the groove wall of the installation groove 110, and the limiter 400 is provided with an elastic protrusion. The side wall of the lens 300 is provided with two spaced apart limit grooves. The two limit grooves are respectively engaged with the elastic protrusion when the lens 300 is in the first rotation position and the second rotation position.

[0043] For example, in this embodiment, an arcuate guide groove 330 is provided through the surface of the lens 300. The axis of the arcuate guide groove 330 is coaxial with the rotation center of the lens 300. The stopper 400 is connected to the housing 100 through the arcuate guide groove 330. When the lens 300 is in a first rotational position, the stopper 400 abuts against one groove wall in the direction in which the arcuate guide groove 330 extends. When the lens 300 is in a second rotational position, the stopper 400 abuts against another groove wall in the direction in which the arcuate guide groove 330 extends. In this way, the stopper 400 can also limit the position of the lens 300. It should be noted that the connection method of the stopper 400 through the arcuate guide groove 330 to the housing 100 can be a detachable connection method such as plug-in connection, screw locking, or snap connection, or a non-detachable connection method such as bonding or riveting, which is not specifically limited here.

[0044] Taking into account that the limit member 400 only limits the rotation of the lens 300 from the first rotation position to the second rotation position, in actual use, the lens 300 may rotate after being touched, so that the corresponding light output angle is inadvertently adjusted. In view of this, in order to prevent the lens 300 from rotating after being located in the first rotation position or the second rotation position, in this embodiment, the lens 300 is also provided with two locking grooves 340, and the two locking grooves 340 are connected to the arc guide groove 330 and are located at both ends of the extension direction of the arc guide groove 330. The limit member 400 is rotatably connected to the shell 100, and a positioning boss 410 is further provided on the outer peripheral wall of the limit member 400. The positioning boss 410 extends into the locking groove 340 under the rotation of the limit member 400 to fix the lens 300. With such arrangement, when the lens 300 is in the first rotation position or the second rotation position, the limit member 400 can be manually rotated. The rotation of the limit member 400 drives the positioning boss 410 to rotate into the locking groove 340 set in the lens 300, thereby limiting the lens 300 so that the lens 300 can no longer rotate, thereby causing the lens 300 to rotate during actual use of the lamp and affecting the light output.

[0045] Considering that the lamp may be used in environments with high humidity or high dust content, and to ensure the service life of the lamp board 200, in this embodiment, the lamp with adjustable light output angle also includes a sealing ring 500. The lens 300 is connected to the housing 100 and clamps the sealing ring 500, and the lamp board 200 is located inside the sealing ring 500. This sealing ring 500 ensures that the lamp board 200 is sealed after being installed in the mounting groove 110, preventing water seepage and causing short circuits, thereby extending the service life of the lamp.

[0046] In addition, a rotating handle 350 is provided on the side of the lens 300 facing away from the housing 100. This makes it convenient for the user to manually rotate the lens 300. In this embodiment, a plurality of rotating handles 350 can be provided, and each rotating handle 350 is arranged at intervals along the rotation direction of the lens 300.

[0047] In this example, see Figures 6 and 7 The lens 300 can be rotated to a third rotational position, which is located between the first and second rotational positions. When the lens 300 is in the third rotational position, the number of lamp beads 210 covered by the first light-transmitting area 310 is greater than the number of lamp beads 210 covered by the second light-transmitting area 320. As a result, the light output angle in the third rotational position is the sum of the light output angle of the first light-transmitting area 310 and the light output angle of the second light-transmitting area 320.

[0048] For example, in this embodiment, the light emission angle of the first light-transmitting area 310 is 110°, and the light emission angle of the second light-transmitting area 320 is 60°. When the lens 300 is located at the third rotation position, the light emission angle is between 110° and 60°.

[0049] Taking into account that the user needs to use the light output angle of the third rotation position, and in order to facilitate the user to stop rotating and position the lens 300 after rotating the lens 300 to the third rotation position, in this embodiment, a positioning bead 360 is provided at the position of the lens 300 at the third rotation position, and a positioning groove 420 is provided on the outside of the corresponding limiting member 400 at the position corresponding to the positioning bead 360. When the lens 300 is rotated to the third rotation position, the positioning column on the lens 300 and the positioning groove 420 on the limiting member 400 are engaged and positioned, and cooperate with each other to give the user a sense of resistance when rotating the lens 300, thereby positioning. In addition, another locking groove 340 is provided on the lens 300 at the position corresponding to the limiting member 400 at the third rotation position. At this time, rotating the limiting member 400 can also make the positioning boss 410 of the limiting member 400 extend into the locking groove 340, thereby limiting the rotation of the lens 300.

[0050] The above description is only part or preferred embodiments of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
