[0002] LED spotlights are lighting fixtures that use light-emitting diodes as light sources. Their characteristic is that the light can be focused into a beam after passing through a reflector or lens and pointed in a specific direction to form a lighting effect with clear boundaries. They are mainly used for accent lighting, emphasizing specific objects or areas, and creating a sense of spatial layering. They are commonly used in home lighting, commercial lighting, and outdoor lighting scenarios and are a relatively common lighting tool. The existing patent announcement number CN219912943U discloses an LED spotlight that is easy to adjust at multiple angles, including a lamp head with connectors on both sides; a support frame located below the lamp head, wherein the support frame includes a horizontally arranged base plate, and a vertically arranged connecting arm on the top of the base plate, the connecting arm being rotatably mounted to the connectors on both sides of the lamp head; a mounting base located below the support frame, the mounting base having a built-in motor, the output end of the motor having a drive shaft, the drive shaft being connected to the support frame; and a positioning component formed between the mounting base and the support frame, used for positioning the mounting base and the support frame, the positioning component including a first positioning hole formed circumferentially on the outer surface of the mounting base, a second positioning hole provided on the side of the base plate facing the positioning hole, the first positioning hole and the second positioning hole being aligned and a positioning pin being inserted; However, it still has the following drawbacks in practical use: 1. The LED spotlights mentioned above use a support frame and a mounting base to install the lamp head. The angle of the lamp head can be adjusted in multiple directions through the movable connection between the support frame and the mounting base, as well as the movable connection between the lamp head and the support frame. However, during use, the mounting base is generally fixed in a designated position with bolts, and the installation position of the lamp head is fixed, which makes it inconvenient to fine-tune the position of the lamp head according to the actual situation after installation. 2. The LED spotlights mentioned above are mounted on the lamp head through a support frame and mounting base, and the angle of the lamp head can be adjusted in multiple directions. However, during use, the shape of the light spot emitted by the lamp head is fixed and unchanging. It is not convenient to select different shapes of light spots according to different needs, and its aesthetics are poor, which is not conducive to distinguishing and highlighting different decorations, commodities or exhibits.

Example

[0032] Please see Figure 1 , Figure 2 , Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, this is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that: the front end of the lamp tube 1 is provided with a light spot assembly 3 for adjusting the shape of the light spot. The light spot assembly 3 includes an adjustment frame 301, a take-up roller 302, a light-shielding cloth 303, a fourth motor 304, and a transmission rod 305. The fourth motor 304 and the transmission rod 305 drive the take-up roller 302 to rotate, and the take-up roller 302 takes up or unrolls the light-shielding cloth 303, so that the light-transmitting holes 303a of different shapes on the light-shielding cloth 303 are aligned with the lamp tube 1, thus solving the problem of the existing inconvenience in adjusting the shape of the light spot.

[0033] Specifically, the adjusting frame 301 is fixedly connected to the front end of the lamp tube 1. The adjusting frame 301 is used to install structures such as the mounting shell 301b. A through groove slightly larger than the outer diameter of the front end of the lamp tube 1 is opened on the end face of the adjusting frame 301 to ensure that the light from the lamp tube 1 can pass through the adjusting frame 301. The top and bottom of the adjusting frame 301 are rotatably connected to the take-up roller 302 via the mounting shell 301b. The mounting shell 301b is used to install the take-up roller 302 and prevent dust from adhering to the take-up roller 302 and other structures. A light-shielding cloth 303 is wound around the take-up roller 302. Multiple light-transmitting holes 303a of different shapes are evenly spaced on the light-shielding cloth 303. The light-shielding cloth 303 and the light-transmitting holes 303a are used to adjust the shape of the light spot of the lamp tube 1. When illumination is not required, the portion of the light-shielding cloth 303 without light-transmitting holes 303a is located within the through groove of the adjusting frame 301. The front end of the lamp tube 1 is sealed to prevent dust from adhering to it. A fourth motor 304 is fixedly connected to one side of the adjusting frame 301 via a fourth mounting bracket 304a. The fourth mounting bracket 304a is used to install the fourth motor 304. The fourth motor 304 is used to drive the transmission rod 305 to rotate. The upper and lower sides of one side of the outer wall of the adjusting frame 301 are rotatably connected to the transmission rod 305. One end of the transmission rod 305 is engaged with the fourth motor 304, and the other end is engaged with the take-up roller 302. The transmission rod 305 is used to drive the fourth motor 304 and the take-up roller 302, so that the transmission rod 305 drives the take-up roller 302 to rotate. The two transmission rods 305 drive the two take-up rollers 302 to rotate in opposite directions, so that the two take-up rollers 302 respectively take up and unwind the light-blocking cloth 303.

[0034] Furthermore, the front end of the lamp tube 1 is threadedly connected to a sleeve 301a, the front end of the sleeve 301a is fixedly connected to the rear end face of the adjustment frame 301, the front end of the outer side wall of the lamp tube 1 is provided with an external thread, and the inner side wall of the sleeve 301a is provided with an internal thread. The take-up rollers 302 are all located inside the mounting housing 301b. A third electromagnetic brake 302b is fixedly connected to one side of the outer wall of the mounting housing 301b. The brake rotor of the third electromagnetic brake 302b is fixedly connected to one end of the take-up roller 302. The third electromagnetic brake 302b is used to limit the rotation of the take-up roller 302. The other end of the take-up roller 302 is fixedly connected to a third bevel gear 302a, which is located on the other side of the outside of the mounting housing 301b. The output shaft of the fourth motor 304 is fixedly connected to a fourth bevel gear 304b, which is located inside the fourth mounting bracket 304a. One end of the transmission rod 305 extends into the interior of the fourth mounting bracket 304a and is fixedly connected to a fifth bevel gear 305a. The two fifth bevel gears 305a mesh above and below the fourth bevel gear 304b, respectively. The fourth bevel gear 304b and the fifth bevel gear... The gear 305a enables the meshing connection between the fourth motor 304 and the transmission rod 305, allowing the fourth motor 304 to drive the two transmission rods 305 to rotate in opposite directions simultaneously. The other end of each transmission rod 305 is fixedly connected to a sixth bevel gear 305b, which meshes with one side of the third bevel gear 302a. The arrangement of the third bevel gear 302a and the sixth bevel gear 305b enables the meshing connection between the take-up roller 302 and the transmission rod 305, allowing the transmission rod 305 to drive the take-up roller 302 to rotate.

[0035] The rest of the structure is the same as in Example 1.

[0036] The operation process of this embodiment is as follows: The fourth motor 304 is started. The output shaft of the fourth motor 304 drives two transmission rods 305 to rotate in opposite directions simultaneously through the meshing connection between the fourth bevel gear 304b and the fifth bevel gear 305a. The transmission rods 305 drive the take-up roller 302 to rotate through the meshing connection between the third bevel gear 302a and the sixth bevel gear 305b. This causes one take-up roller 302 to take up the light-blocking cloth 303 and the other take-up roller 302 to unwind the light-blocking cloth 303. As a result, the light-transmitting holes 303a of different shapes on the light-blocking cloth 303 are located in the through groove of the adjustment frame 301. The shape of the light spot of the lamp tube 1 is adjusted by the different shapes of the light-transmitting holes 303a, thereby realizing the adjustment of the light spot shape of the lamp tube 1.
