[0004] Regarding the above-mentioned related technologies, when the installation location of the lamp is difficult to reach, it is difficult for users to adjust the focusing degree of the lamp. Summary of the Invention

[0005] In order to facilitate users to adjust the focus of the lamp, the present application provides a lamp with adjustable focus.

[0006] The present application provides a light-adjustable lamp that adopts the following technical solution:

[0007] A light fixture with adjustable concentration, comprising a lamp housing, a light source assembly, and an adjustment assembly, wherein the light source assembly is used for emitting light and is arranged in the lamp housing;

[0009] By adopting the above technical solution, when the focus of the lamp needs to be adjusted, the adjustment motor drives the driving gear to rotate, which in turn drives the driven gear to rotate, thereby rotating the adjustment cylinder. As the adjustment cylinder rotates, the thread between the adjustment cylinder and the adjustment base extends or retracts, thereby adjusting the distance between the focusing lens and the light source assembly, thereby adjusting the focus of the lamp. This is convenient and quick, reducing the need for manual adjustment.

[0010] Optionally, the adjustment seat is provided with a seat cavity, the adjustment cylinder is engaged with the adjustment seat through the seat cavity thread, the adjustment cylinder is provided with a cylinder cavity, the cylinder cavity is connected to the seat cavity, the focusing lens cover is arranged in the cylinder cavity, and the driven gear, driving gear and adjustment motor are all located outside the cylinder cavity.

[0011] By adopting the above technical solution, the light emitted by the illumination component passes through the seat cavity, the cylindrical cavity and the focusing lens in sequence, which is beneficial to reduce the situation where the driven gear, the driving gear and the adjustment motor affect the light path.

[0012] Optionally, the diameter of the driven gear is larger than the diameter of the driving gear.

[0013] By adopting the above technical solution, it is convenient to drive the adjusting cylinder to extend or retract by overcoming the friction force of the thread through the adjusting motor with relatively small size and power.

[0014] Optionally, the light source assembly includes a circuit board and an LED lamp, the circuit board is mounted on the lamp housing, and the LED lamp is electrically connected to the circuit board.

[0015] By adopting the above technical solution, the LED lamp has a smaller volume and lower energy consumption, which is beneficial to reducing the volume and energy consumption of the adjustable concentration lamp.

[0016] Optionally, the lamp housing is installed with a decorative cover plate, the decorative cover plate is arranged to cover the light source assembly and the adjustment assembly, and a light-transmitting hole is opened through the decorative cover plate.

[0019] By adopting the above technical solution, it is easy to prevent external dust from entering the interior of the lamp housing.

[0020] Optionally, the adjustable-concentration lamp further includes a limit assembly, which is used to limit the maximum amount of movement of the adjustment tube when it extends forward.

[0021] By adopting the above technical solution, it is helpful to reduce the occurrence of the driven gear slipping off the driving gear, thereby improving the reliability of the adjustable light concentration lamp.

[0022] Optionally, the limit assembly includes a limit seat and a limit ring, the limit seat is installed on the lamp housing, the limit seat is provided with a limit protrusion, the limit protrusion is located on the outer circumference of the limit seat, the limit ring is slidably sleeved on the outer circumference of the limit seat, and the adjustment cylinder is installed on the limit ring.

[0023] By adopting the above technical solution, when the driven gear is about to slip off the driving gear, the limiting ring is tightly fitted with the limiting protrusion, so that the adjusting cylinder is not likely to extend too far.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. To adjust the light's focus, the motor drives the active gear, which in turn drives the driven gear, causing the adjustment cylinder to rotate. As the adjustment cylinder rotates, the thread between the adjustment cylinder and the adjustment base extends or retracts, adjusting the distance between the focusing lens and the light source assembly. This allows for quick and easy adjustment, reducing the need for manual adjustments.

[0026] 2. The light emitted by the illumination component passes through the base chamber, the cylinder chamber and the focusing lens in sequence, which helps to reduce the influence of the driven gear, the driving gear and the regulating motor on the light path;

[0027] 3. Before the driven gear is about to slip off the driving gear, the limiting ring is tightly fitted with the limiting protrusion, so that the adjusting cylinder is not likely to extend too far. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following is combined with Figure 1-7 This application is described in further detail.

[0037] Example 1:

[0038] The embodiment of the present application discloses a light fixture with adjustable concentration. Figure 1 The concentration adjustable lamp includes a lamp housing 1, a light source component and an adjustment component 4.

[0039] Reference Figure 1 The lamp housing 1 is arranged in a cubic shape, and one side of the lamp housing 1 is rotatably matched with a rotating seat, which is used to be fixedly installed on the surface of other objects, so that the lamp with adjustable focusing can illuminate different positions by rotating the lamp housing 1.

[0040] Reference Figure 2 The interior of the lamp housing 1 defines a housing chamber, within which the light source assembly and adjustment assembly 4 are located. The light source assembly includes a circuit board 2 and an LED lamp 3. The circuit board 2 is fixedly mounted to the bottom of the housing chamber. The LED lamp 3 is electrically connected to one side of the circuit board 2, thereby facilitating illumination through the LED lamp 3 and reducing energy consumption and volume of the light source assembly.

[0041] Reference Figure 3 and Figure 4The adjustment assembly 4 includes an adjustment seat 41, an adjustment cylinder 42, an adjustment motor 43 and a focusing lens 44. The adjustment seat 41 is fixedly mounted on the bottom of the groove of the lamp housing 1, and the adjustment seat 41 and the LED lamp 3 are located on the same side of the circuit board 2. The adjustment seat 41 is provided with a seat cavity 411, and the adjustment seat 41 is sleeved on the LED lamp 3. The adjustment cylinder 42 is threadedly engaged with the adjustment seat 41 through the seat cavity 411, so that by rotating the adjustment cylinder 42, the adjustment cylinder 42 can be extended or retracted relative to the adjustment seat 41. The adjustment cylinder 42 is provided with a cylinder cavity 421, and the cylinder cavity 421 is connected to the seat cavity 411. The focusing lens 44 is fixedly mounted on the adjustment cylinder 42, and the focusing lens 44 is covered in the cylinder cavity 421, so that the light from the LED lamp 3 passes through the seat cavity 411, the cylinder cavity 421 and the focusing lens 44 in sequence.

[0042] The adjustment motor 43 is fixedly mounted on the adjustment base 41. A driving gear 431, also known as a spur gear, is coaxially mounted on the output shaft of the adjustment motor 43. Both the driving gear 431, the adjustment motor 43, and the driving gear 431 are located outside the barrel chamber 421. A driven gear 422, also known as a spur gear, is fixedly mounted on the outer circumference of the adjustment barrel 42. The driven gear 422 meshes with the driving gear 431. The diameter of the driven gear 422 is larger than that of the driving gear 431, and the length of the driving gear 431 is greater than that of the driven gear, allowing the adjustment motor 43 to drive the adjustment barrel 42 forward or backward relative to the adjustment base 41.

[0043] Reference Figure 1 and Figure 2 The lamp housing 1 is fixedly mounted with a decorative cover plate 11, which covers the light source assembly and the adjustment assembly 4. The decorative cover plate 11 is located in front of the focusing lens 44, so that the style of the decorative cover plate 11 can be adjusted according to the user's needs, thereby improving the user's satisfaction. The decorative cover plate 11 is penetrated by a light-transmitting hole 111, which is arranged opposite the focusing lens 44, so that light can pass through the light-transmitting hole 111 and penetrate the decorative cover plate 11 after passing through the focusing lens 44. The lamp housing 1 is fixedly mounted with an outer lens 12, which is covered by the decorative cover plate 11 to prevent external dust from entering the interior of the lamp housing 1.

[0044] The first embodiment of the present application is a light fixture with adjustable focus. The principle of implementation is as follows: when the focus of the lamp needs to be adjusted, the driving gear 431 is driven to rotate by the adjustment motor 43, which in turn drives the driven gear 422 to rotate, thereby rotating the adjustment cylinder 42. When the adjustment cylinder 42 rotates, the thread between the adjustment cylinder 42 and the adjustment seat 41 is extended or retracted, thereby adjusting the distance between the focusing lens 44 and the LED lamp 3, thereby adjusting the focus of the lamp. This is convenient and quick, and reduces the need for manual adjustment.

[0045] Example 2:

[0046] The present application discloses a lamp with adjustable concentration, which includes all the technical features of Example 1 and also includes the following technical features:

[0047] Reference Figure 5 and Figure 6 The adjustable-focus lamp also includes a limit assembly, which includes a limit seat 6 and a limit ring 7. The limit seat 6 is fixedly mounted on the bottom of the groove of the lamp housing 1. The limit seat 6 is hollow and located inside the seat cavity 411. The limit seat 6 and the seat cavity 411 are coaxially arranged. A limit protrusion 61 is provided on the outer circumference of the limit seat 6. The limit protrusion 61 is closed end to end and arranged in an annular shape. The limit protrusion 61 is integrally connected to the limit seat 6. The limit ring 7 is slidably sleeved on the limit seat 6 and is located between the limit protrusion 61 and the circuit board 2 so that the maximum forward movement of the limit ring 7 is limited by the limit protrusion 61. Four snap-fit ​​grooves 412 are provided on the inner wall of the barrel chamber 421, and the limiting ring 7 is provided with four elastic snap-fit ​​protrusions 71. The four snap-fit ​​protrusions 71 are respectively snap-fitted into the four snap-fit ​​grooves 412, so as to facilitate the installation of the limiting ring 7 on the adjustment barrel 42, thereby limiting the maximum movement of the adjustment barrel 42 when it extends forward through the limiting component, reducing the occurrence of the driven gear 422 slipping off the driving gear 431, and ensuring the reliability of the light-adjustable lamp.

[0048] Reference Figure 7 The limiting protrusion 61 is fixedly mounted with a forward extension buffer pad 611, which is closed at both ends and arranged in an annular shape. The forward extension buffer pad 611 is located between the limiting protrusion 61 and the limiting ring 7, so that the limiting ring 7 and the limiting protrusion 61 are not easily in direct contact when extending, thereby reducing the wear between the limiting ring 7 and the limiting protrusion 61, thereby improving the service life of the limiting seat 6 and the limiting ring 7. In addition, the adjustment seat 41 is fixedly mounted with a retraction buffer pad 413, which is closed at both ends and arranged in an annular shape. The retraction buffer pad 413 is located between the driven gear 422 and the adjustment seat 41, so that the adjustment cylinder 42 and the adjustment seat 41 are not easily in direct contact when retracting, thereby reducing wear.

[0049] The implementation principle of the adjustable-focus lamp in Example 2 of the present application is as follows: the limiting protrusion 61 provided on the adjustment seat 41 limits the limiting ring 7 provided on the adjustment tube 42, so that the adjustment tube 42 is not prone to excessive extension when extending forward, thereby improving the reliability of the adjustable-focus lamp.

[0050] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
