Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and in particular to a lighting fixture with interchangeable component positions. Background Technology

[0002] Currently, lighting fixtures such as downlights and ceiling lights are equipped with panels such as atomizing panels, focusing panels, diffused panels, and color rendering panels, depending on actual needs, or they may not be equipped with panels at all. In order to facilitate the configuration of functional panels, corresponding installation structures such as slots are usually pre-set on the lighting fixtures. However, if the corresponding functional panels are not installed, the installation structures such as slots will be exposed, which is more likely to cause problems such as light leakage and dust intrusion. Therefore, lighting fixtures with and without panels need to be designed and manufactured independently, which has poor versatility and high production costs.

[0003] To address this, the applicant previously filed a Chinese utility model patent with patent number "CN202322944940.3" entitled "Lighting Fixture with Changeable Usage Form". This patent changes the position of the inner ring by altering the position of the hook structure to meet the requirements of form change. However, in practical applications, the change operation is rather cumbersome and inconvenient to use. Utility Model Content

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0029] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They 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. Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] like Figures 1 to 7 As shown, the lamp with a changeable component position according to an embodiment of the present invention includes a lamp housing 100, an inner ring 200, and a position adjustment mechanism. The lamp housing 100 is provided with a light source cavity 101 for mounting a light source assembly 900. The inner wall of the light source cavity 101 is provided with at least one mounting structure for mounting external components. The inner ring 200 is rotatably disposed within the light source cavity 101. The inner ring 200 is configured to rotate along a first rotation direction and a second rotation direction, wherein the first rotation direction is opposite to the second rotation direction. The position adjustment mechanism includes a limiting block 110 disposed on the inner wall of the light source cavity 101 and a limiting block 110 disposed on the outer wall of the inner ring 200 and capable of supporting the limiting block 110. 10. A sliding position adjustment groove 210 is provided, which includes a first track 211 extending along a second rotation direction and a second track 212 extending along a first rotation direction. The light source cavity 101 is set to open upward, and upward is set as the height direction. The first track 211 is higher than the second track 212. When the inner ring 200 is rotated along the first rotation direction, the limiting block 110 slides into the first track 211, and the inner ring 200 is in the first position, with the mounting structure exposed. When the inner ring 200 is rotated along the second rotation direction, the limiting block 110 slides into the second track 212, and the inner ring 200 is in the second position, with the mounting structure blocked by the inner ring 200.

[0033] The position of the inner ring 200 can be changed by rotating the inner ring 200, so as to expose or cover the installation structure and meet the different usage requirements of the lamp.

[0034] Specifically, such as Figures 5 to 7As shown, since the first track 211 on the outer wall of the inner ring 200 is higher than the second track 212, that is, the first track 211 is closer to the upper end of the inner ring 200, when the limiting block 110 slides into the first track 211 (that is, when the inner ring 200 is in the first position), the position of the inner ring 200 inside the lamp housing 100 is lower, that is, the inner ring 200 in the first position is lower than the inner ring 200 in the second position.

[0035] The inner ring 200 in the second position (high position) can completely shield the installation structure to reduce problems such as light leakage and dust intrusion.

[0036] The inner ring 200 in the first position (low position) allows the mounting structure to be exposed for mounting external components such as atomizing panels, focusing panels, diffused panels, color rendering panels, etc., to meet different usage requirements of the luminaire.

[0037] like Figure 4 As shown, in some embodiments of this utility model, the first rotation direction is counterclockwise and the second rotation direction is clockwise.

[0038] Of course, in the specific implementation process, the positions of the first track 211 and the second track 212 can also be reversed, that is, the first track 211 is set to be lower than the second track 212. In actual adjustment, the rotation direction of the inner ring 200 is opposite to that of the above, so that the same adjustment of the height of the inner ring 200 can be achieved.

[0039] It should be noted that, in this utility model, for ease of description, a first rotation direction, a second rotation direction, and an orientation are defined, rather than indicating or implying that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0040] like Figure 4 , Figure 7 As shown, in some embodiments of this utility model, the position adjustment groove 210 further includes an inlet cavity 213. The two sides of the inlet cavity 213 are respectively connected to the first track 211 and the second track 212. The lower end of the inlet cavity 213 is an open structure, and the limiting block 110 can enter the inlet cavity 213 from bottom to top through the open structure, which facilitates the insertion and adjustment of the inner ring 200.

[0041] Specifically, the inner ring 200 is inserted into the light source cavity 101 from top to bottom. When the limiting block 110 is aligned with the opening structure at the lower end of the inlet cavity 213, the limiting block 110 enters the inlet cavity 213 (e.g., Figure 4 (As shown); when the inner ring 200 rotates in the first rotation direction, the limiting block 110 enters the first track 211, the inner ring 200 is in the first position, and the mounting structure (mounting hole 102) is exposed (as shown). Figure 5(As shown); when the inner ring 200 rotates in the second rotation direction, the limiting block 110 enters the second track 212, the inner ring 200 is in the second position, and the mounting structure (mounting hole 102) is blocked (as shown). Figure 6 (As shown).

[0042] like Figure 7 As shown, in some embodiments of this utility model, the inlet cavity 213 is connected to the first track 211 via the first lifting track 214.

[0043] like Figure 7 As shown, in some embodiments of this utility model, the inlet cavity 213 is connected to the second track 212 via the second lifting track 215.

[0044] like Figure 5 , Figure 7 As shown, in some embodiments of this utility model, a first protrusion 211a is provided in the first track 211, and the limiting block 110 can pass over the first protrusion 211a in the second rotation direction. The first protrusion 211a can restrict the limiting block 110 from moving in the first rotation direction, that is, the limiting block 110 is limited in the first track 211, so that the inner ring 200 can be maintained in the first position when it is not subjected to external force.

[0045] like Figure 6 , Figure 7 As shown, in some embodiments of this utility model, a second protrusion 212a is provided in the second track 212, and the limiting block 110 can pass over the second protrusion 212a in the first rotation direction. The second protrusion 212a can restrict the limiting block 110 from moving in the second rotation direction, that is, the limiting block 110 is limited in the second track 212, so that the inner ring 200 can be maintained in the second position when it is not subjected to external force.

[0046] Specifically, the inner ring 200 is generally a plastic part or a thin shell with a certain elastic deformation performance. Under a certain external force, the limiting block 110 can pass over the first protrusion 211a or the second protrusion 212a, thereby realizing the reverse limiting of the limiting block 110 and preventing the limiting block 110 from sliding out automatically.

[0047] In some embodiments of this utility model, the first protrusion 211a and / or the second protrusion 212a have a semi-circular cross-section to guide the limiting block 110 to pass over.

[0048] like Figure 2 As shown, in some embodiments of this utility model, the mounting structure is a mounting hole 102 provided on the inner wall of the light source cavity 101, which can cooperate with the snap-fit ​​structure of the external component to snap the external component.

[0049] Specifically, when the inner ring 200 is in the first position, the upper end of the mounting hole 102 is exposed so that the snap-fit ​​structure of the external component can be inserted; when the inner ring 200 is in the second position, the mounting hole 102 is completely covered.

[0050] It is understood that in some embodiments of this utility model, the mounting structure may also be a snap-fit ​​or similar mechanism.

[0051] like Figure 6 As shown, in some embodiments of this utility model, when the inner ring 200 is in the second position, the upper end of the inner ring 200 is approximately level with the upper end of the lamp housing 100.

[0052] In some embodiments of this utility model, the inner ring 200 is a reflector cup to control the light from the light source assembly 900, and the light effect can also be adjusted by adjusting the position of the inner ring 200.

[0053] Specifically, the inner ring 200 has a flared structure to facilitate the diffusion of light.

[0054] like Figure 2 , Figure 3 , Figure 7 As shown, in some embodiments of this utility model, an installation part 220 is provided extending downward from the upper edge of the inner ring 200, a position adjustment groove 210 is provided on the outer wall of the installation part 220, and a stepped structure 103 is provided on the inner wall of the light source cavity 101, which allows the installation part 220 to be inserted from top to bottom. A limiting block 110 is provided on the side wall of the stepped structure 103 to improve the fit between the position adjustment groove 210 and the limiting block 110.

[0055] Specifically, the inner ring 200 and the light source cavity 101 are generally non-cylindrical structures such as bowl-shaped or trumpet-shaped. The position adjustment groove 210 extends along the arc on the outer wall of the inner ring 200, which is relatively troublesome to set up and has poor matching accuracy with the limiting block 110. A mounting part 220 is provided extending downward at the upper edge of the inner ring 200. The mounting part 220 is a cylindrical ring structure or a slightly tapered cylindrical structure. The side wall of the stepped structure 103 corresponds to it, which facilitates the setting of the position adjustment groove 210 and the limiting block 110 and can obtain higher matching accuracy.

[0056] In some embodiments of this utility model, the position adjustment groove 210 is configured as three, and the limiting block 110 is configured in a one-to-one correspondence with the position adjustment groove 210, so that the inner ring 200 can be stably installed on the lamp housing 100.

[0057] It is understood that, in some embodiments of this utility model, the position adjustment slot 210 may also be configured as two, four or more as needed.

[0058] Of course, this invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
