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.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise expressly specified. "Several" means one or more, unless otherwise expressly specified.

[0038] In the description of this application, it should be noted that, unless otherwise expressly 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0039] Please see Figure 1 and Figure 2 The zoom mechanism of this embodiment includes: a support module 1, an LED module 2, and a drive module 3. The LED structure 2 is mounted on the support module 1, and the drive module 3 is mounted on the support module 1 and drives the LED structure 2 to zoom according to the received instructions.

[0040] In a preferred embodiment, the support module 1 includes: a first mounting plate 11, and a second mounting plate 13 with a spacing between it and the first mounting plate 11 and supported by a plurality of fixing rods 12, wherein a limiting groove 111 is formed on the first mounting plate 11.

[0041] In a preferred embodiment, the LED module 2 includes: a plurality of lens structures 21 fixed by the support rod 12 and disposed on one side of the second mounting plate 13, and an LED structure 22 mounted on the second mounting plate 13 and corresponding to each lens structure 21. Specifically, each LED structure 21 includes: an LED housing a1 connected to the fixing rod 12, and a lens a2 mounted on the LED housing a1 and protruding from one side of the LED housing a1, wherein each LED housing a1 is fixed by at least two fixing rods 12.

[0042] The drive module 3 includes: a stepper motor 31 that passes through the first mounting plate 11 and the second mounting plate 13, drives the displacement between the lens structure 21 and the lamp bead structure 22, and realizes the focal length adjustment; and a limiting plate structure 33 that is linked with the stepper motor 31 and moves within the limiting groove 111. The limiting plate structure 33 includes: a fixed support plate b1 that is fixed by a lead screw connected to the stepper motor 31; and a limiting plate b2 that is fixed on one side of the fixed support plate b1 and extends into the limiting groove 111 at the other end. When the stepper motor 31 rotates, it drives the limiting plate b2 to move within the limiting groove 111, and drives the lamp bead structure 21 mounted on the second mounting plate 13 to move, adjusting the distance between the lamp bead structure 22 and the lens a2, thereby realizing the focusing function.

[0043] It should be noted that this product is used in lighting fixtures. The lamp module 2 also has a circuit board for receiving control signals. Specifically, the circuit board receives signals such as those from a mobile terminal to instruct the stepper motor 31 to move. This technique is an application of existing technology, so it is not described in detail here.

[0044] In this embodiment, the zoom mechanism, when the circuit board receives a zoom command, instructs the stepper motor 31 to move. The lead screw connected to the stepper motor 31 drives the second mounting plate 13 to move, thereby driving the lamp bead structure 22 to move. Since the lens a2 and the lamp bead shell a1 are fixed by the fixing rod 12, the distance between the lamp bead structure 22 and the lens a2 can be adjusted by the stepper motor 31, thus realizing the focusing function of this product. In addition, this product assembles the drive module 3 and the lamp bead module 2 into an integrated structure through the support module 1, making the product more convenient and simple to use and install. At the same time, the reasonable structural design helps to improve the versatility of the product, thereby reducing production costs.

[0045] Please combine Figure 3The difference between the zoom mechanism in this embodiment and the above embodiment is that the zoom mechanism in this embodiment further includes: a plurality of reflector structures 41 corresponding to each of the lamp bead structures 22 integrally formed, the reflector structures 4 being cylindrical, the reflectors 41 being regularly formed on the reflector structures 4, and the inner sidewall of each of the reflectors 41 being formed with serrated patterns.

[0046] The zoom mechanism 4 in this embodiment, through the use of the reflector structure 4, enables the product to have better light spot optimization function.

[0047] Please combine again Figure 4 and Figure 5 The application in this embodiment includes a projection lamp with a zoom mechanism, such as: Figure 1 and Figure 2 The zoom mechanism described in this embodiment includes a lamp body 01 sleeved on the outer periphery of the zoom mechanism, a second reflector structure 04 mounted on one side of the zoom mechanism, and a glass structure 02 mounted on the other side of the second reflector structure 04. The structure of the second reflector structure 04 is consistent with the structure of the reflector structure 4 in the above embodiment; please refer to the description of the above embodiment for details.

[0048] This product is used in projection lamps with zoom mechanisms. By using the zoom mechanism, this product has the advantages of reasonable structural design and low production cost. In addition, this product also has the advantage of good light spot optimization effect.

[0049] Please combine again Figure 6 and Figure 7 The projection lamp with a zoom mechanism in this embodiment also includes a bracket 5, which includes: a base 51, a rotating handle 52 installed in the base 51, a support 53 installed on the base 51 and supported by the rotating handle 52, and a waterproof pad 54 installed between the support 53 and the lamp body 01. In some other preferred embodiments, the bracket 5 can also be replaced with a clamp, which is fixed to the support rod to meet the usage requirements of the product in different occasions.

[0050] The projector in this embodiment, through the use of the bracket 5, makes the product easy to adjust in angle.

[0051] Please combine Figure 8 The application of this embodiment includes in-ground lights with zoom mechanisms, such as: Figure 3 The zoom mechanism of the embodiment includes a lamp body 2 6 sleeved on the outer periphery of the zoom mechanism and a bracket 2 7 rotatably connected to the lamp body 2 6.
