Description

Technical Field

[0001] This utility model relates to a light-changing structure and a lamp, and more particularly to a focusing structure and a surface-mounted lamp. Background Technology

[0002] Existing surface-mounted lighting fixtures on the market generally adopt a fixed structure, and different lighting needs usually require the purchase of different models. The core of the lighting effect lies in the different focal lengths of the lenses. Subsequently, some lighting fixtures with adjustable focal lengths appeared, such as CN120777505A and CN119778684A. These two disclose two different focusing structures and lighting fixtures, but their structures are complex and have many parts, making them unsuitable for surface-mounted lighting fixtures. Therefore, a simpler and more stable structure is needed. Utility Model Content

[0003] In view of the above situation, it is necessary to provide a focusing structure and surface-mounted lamp that solve at least one of the above problems.

[0004] This utility model provides a focusing structure, including a lens mount, and further comprising:

[0005] First focusing section, second focusing section;

[0006] The first focusing section is provided with a first guide section;

[0007] The second focusing part is disposed outside the first focusing part, and the two can move relative to each other. The second focusing part is provided with a second guide part.

[0008] The lens mount is disposed within the first focusing section, and the lens mount is provided with a guide pin, which passes through the first guide section and cooperates with the second guide section.

[0009] When the first focusing section and the second focusing section move relative to each other, the lens mount moves within the first focusing section, moving away from or closer to the light source.

[0010] As a further embodiment of this utility model: the first focusing part and the second focusing part are in a ring structure, the second focusing part is sleeved on the outside of the first focusing part, and the two can rotate relative to each other.

[0011] As a further embodiment of this utility model: the first guide portion is an obliquely arranged elongated hole, and is located on the side wall of the first focusing portion;

[0012] The second guide portion is an axially arranged groove;

[0013] The axial height h1 of the first guide part is less than or equal to the axial height h2 of the second guide part.

[0014] This utility model also provides a surface-mounted lamp, including a lamp housing and a focusing structure as described in any of the above.

[0015] The aforementioned focusing structure employs a dual-focusing mechanism for rapid focusing, which remains stable once focused. Furthermore, it features few parts, a simple structure, and ease of use and maintenance. When installing this focusing structure on surface-mounted lighting fixtures, it offers the advantage of installation before adjustment, resolving the pain point of repeated adjustments required before installation in traditional lighting fixtures.

[0023] To make the objectives, technical solutions, and advantages of this 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 this utility model and are not intended to limit this utility model.

[0024] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "center," "longitudinal," "lateral," "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] like Figure 1-4 As shown, this embodiment provides a focusing structure, including a cylindrical first focusing part 400 and a second focusing part 500. The second focusing part 500 is sleeved on the outside of the first focusing part 400, and the second focusing part 500 can rotate freely on the first focusing part 400.

[0027] A lens mount 200, on which a lens 600 is mounted, is disposed inside the first focusing section 400, and a guide pin 210 is provided on the lens mount 200. Corresponding to the position of the guide pin 210, a first guide portion 410 and a second guide portion 510 are respectively provided on the first focusing section 400 and the second focusing section 500.

[0028] The first guide portion 410 is an obliquely elongated hole, and the second guide portion 510 is an axially elongated notch. It is readily apparent that the shape of the second guide portion 510 is not limited to a notch shape; it depends on the axial length of the second focusing portion 500. When the length of the second focusing portion 500 is sufficient, it can also be an elongated hole. Furthermore, the first guide portion 410 and the second guide portion 510 intersect each other, and their intersections are connected.

[0029] After the guide pin 210 passes through the first guide portion 410 from the inside to the outside, it cooperates with the second guide portion 510. The guide pin 210 is located at the intersection of the two guide portions mentioned above.

[0030] When the first focusing section 400 and the second focusing section 500 rotate relative to each other, their intersection point changes, causing the guide pin 210 to move along with the intersection point, thereby changing the position of the lens mount 200. Specifically, when the second focusing section 500 rotates, the side wall 511 of the second guide section 510 presses against the guide pin 210, providing a lateral force that forces it to move along the direction of the first guide section 410. Since the first guide section 410 is an inclined hole, the guide pin 210 moves axially while moving in the circumferential direction, meaning the lens mount extends and retracts within the first focusing section 400, achieving the focusing function. After adjustment, since the first focusing section 400 and the second focusing section 500 are in direct contact, there is a certain friction between them. As long as the second focusing section 500 is not manually touched, the optical focus will not change due to external factors such as gravity or vibration, resulting in good stability.

[0031] Furthermore, the axial height h1 of the first guide portion 410, that is, the projected height of the lowest point to the highest point of the first guide portion 410 on the axis, needs to be less than or equal to the axial height h2 of the second guide portion 510 to prevent the guide pin 210 from disengaging from the second guide portion 510 during focusing. Based on the foregoing, it is easy to understand that h1 is the maximum adjustable range of this focusing structure.

[0032] As shown in Figure 5- Figure 7 As shown, this embodiment also provides a surface-mounted lighting fixture, including the aforementioned focusing structure. Specifically, it includes a lighting fixture housing 100, and the focusing structure is disposed on the lighting fixture housing 100.

[0033] Furthermore, the lamp housing 100 includes a housing 110 and an LED mounting plate 120, which are fixedly connected. The LED mounting plate 120 is provided with LED beads 121 as a light source. The LED mounting plate 120 is assembled with the first focusing part 400 via threads 122.

[0034] After the lamp housing 100 is assembled with the focusing structure, the housing 110 and the first focusing part 400 sandwich the extension 520 of the second focusing part 500 in between. Specifically, as shown... Figure 7 As shown, the extension 520 is the portion where the second guide portion 510 is provided. Simultaneously, the housing 110 restricts the axial freedom of the second focusing portion 500, allowing it to only rotate. This structure further increases the frictional force during the rotation of the second focusing portion 500, improving stability after focusing. Using this focusing structure in surface-mounted lighting fixtures enables the fixture to be adjusted after installation, solving the problem that traditional lighting fixtures must be adjusted before installation.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
