[0048] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0049] like Figures 1-3 As shown, the present application relates to a structure with adjustable beam angle and an LED spotlight. Figure 1 and 3 As shown, the beam angle adjustable structure includes: a moving platform 10; the moving platform 10 refers to a platform that has the function of moving and carrying other components, which can achieve a good moving effect, and at the same time, can also achieve the effect of multiple components cooperating with each other, thereby achieving multiple functional effects.

[0050] Preferably, the mobile platform 10 is disc-shaped, which can ensure good matching and movement effects.

[0051] Furthermore, the mobile platform 10 is provided with a plurality of mounting holes, which can achieve good assembly and fixing effects. Preferably, the plurality of mounting holes are connected to the lens bracket 30 through a plurality of first connecting members 170, which can ensure corresponding fastening connection effects. More preferably, the first connecting member 170 includes but is not limited to: screws or bolts, which can achieve an effect of easy operation and at the same time ensure good fastening force.

[0052] Furthermore, the mobile platform 10 is provided with a plurality of reinforcing ribs, which can achieve the effect of improving the structural strength.

[0053] The adjusting component 20 is meshed with the extension part 101 provided at the bottom of the mobile platform 10 along a preset direction; by providing the adjusting component 20, a good adjustment effect can be achieved; at the same time, the adjusting component 20 is meshed with the extension part 101 of the mobile platform 10 to ensure a precise angle adjustment effect. The preset direction is the horizontal direction; by adopting the horizontal direction setting, a good displacement effect in the vertical direction can be achieved. Preferably, the adjusting component 20 is an adjustment rod.

[0054] The lens bracket 30 is connected to the mobile platform 10 on the side away from the adjustment component 20, which can achieve a good fixing and supporting effect of the lens 40, thereby ensuring that the lens 40 is in a stable state; at the same time, it can also provide a basis and guarantee for driving the directional movement of the lens 40. Preferably, the number of lens brackets 30 is four, and the four lens brackets 30 are evenly arranged along the circumferential direction of the mobile platform 10, which can ensure a stable support effect.

[0055] The lens 40 is disposed in the lens holder 30 , and can achieve a good assembly effect. Meanwhile, the lens 40 can control the direction, shape and intensity of the light beam, thereby achieving more efficient optical performance.

[0056] Specifically, the applications of the lens 40 in an LED spotlight can include but are not limited to the following aspects: Beam control, spotlighting: By using a convex lens or a combination lens, the LED spotlight can concentrate the beam into a smaller angle to achieve a spotlighting effect. This is very important for occasions that require high-brightness concentrated lighting, such as exhibition displays, stage lighting, etc.

[0057] Diffusion: By using a concave lens or a diffusing lens, the beam can be diverged into a larger angle to provide uniform lighting. This is particularly important in occasions that require extensive lighting, such as home lighting, mall lighting, etc.

[0058] Optical design, optical efficiency: The lens 40 can reduce the scattering and loss of light, improve the overall efficiency of the optical system, make more light concentrate on the target area, and improve the brightness and energy-saving effect.

[0059] Uniformity: The design of the lens 40 can optimize the uniformity of the light spot, avoid the phenomenon of the center of the light spot being too bright or the edge being too dark, so as to provide a more uniform lighting effect.

[0060] Preferably, the materials of the lens 40 include but are not limited to the following: Glass lens: It has good optical properties and high-temperature resistance, but is heavier and has a higher cost, and is suitable for high-end or special-requirement lighting applications.

[0061] Plastic lens: Such as PMMA (acrylic) and PC (polycarbonate), which have the characteristics of light weight, low cost, and easy processing, and are widely used in ordinary LED spotlights.

[0062] Among them, the adjusting member 20 is rotated at a preset rotation angle, and drives the moving platform 10, the lens bracket 30 and the lens 40 to move directionally, so that the lens 40 approaches or moves away from the preset light source 70. By adjusting the preset angle of the adjusting member 20, the adjusting member 20 synchronously drives the extension portion 101 to move in the vertical direction due to rotation, and will drive the moving platform 10, the lens bracket 30 and the lens 40 to move directionally, so as to achieve the effect of adjusting the position of the lens 40, and further achieve the effect of adjusting the position of the lens 40 and the preset light source 70, and finally achieve the effect of adjusting the beam angle.

[0063] In this application, the gear on the rotating adjusting member 20 drives the rack 1011 on the moving platform 10 to move, so as to change the distance between the light source 70 and the lens 40, thereby achieving the effect of changing the beam angle and realizing the change of the lighting range. Using the product of this application can meet various lighting needs, and users can adjust the corresponding beam angle according to different usage environments.

[0064] Specifically, the present application provides a structural solution for adjusting the beam angle of a spotlight, enabling the lamp to produce different lighting effects at a fixed position. By rotating the adjusting rod, its gear structure 201 will drive the rack 1011 structure on the moving platform 10, driving the moving platform 10 to move up and down, and then driving the lens bracket 30 and the lens 40 connected to the platform to move up and down. Since the position of the light source 70 is fixed, when the lens 40 moves, the distance between it and the light source 70 changes. When the distance decreases, the beam angle of the spotlight becomes larger; when the distance increases, the beam angle of the spotlight becomes smaller.

[0065] Of course, the gear transmission system consists of two or more gears, and motion and force are transmitted through the meshing between the gears. The following are some key concepts:

[0066] Gear ratio: The gear ratio is the ratio of the number of teeth of the driving gear to the driven gear. Among them, the gear ratio formula is:

[0067]

[0068] For example: If the driving gear has 20 teeth and the driven gear has 40 teeth, the transmission ratio is 40 / 20 = 2. This means that when the driving gear rotates 2 circles, the driven gear rotates 1 circle.

[0069] Rotation direction: Meshing gears usually rotate in opposite directions. If the driving gear rotates clockwise, the driven gear will rotate counterclockwise.

[0070] Angular velocity relationship: The gear ratio not only affects the rotation angle but also the angular velocity. The angular velocity is inversely proportional to the gear ratio. Among them, the formula is:

[0071]

[0072] In the formula, ω1 is the angular velocity of the driving gear, and ω2 is the angular velocity of the driven gear.

[0073] Rotation angle relationship: If the rotation angle of the driving gear is known, the rotation angle of the driven gear can be calculated through the transmission ratio. Among them, the formula is:

[0074]

[0075] In the formula, θ1 is the rotation angle of the driving gear, and θ2 is the rotation angle of the driven gear.

[0076] Example: Assume that the driving gear A has 30 teeth and the driven gear B has 60 teeth. The gear transmission ratio is 60 / 30 = 2. If gear A rotates 360 degrees (one full turn), gear B will rotate 180 degrees (half a turn). If the angular velocity of gear A is 60 RPM (revolutions per minute), the angular velocity of gear B will be 30 RPM.

[0077] From the above description, it can be seen that the present application achieves the following technical effects:

[0078] In the embodiment of the present application, a method of adjustable beam angle is adopted. By rotating the adjusting member 20 at a preset rotation angle, the moving platform 10, the lens holder 30, and the lens 40 are driven to move directionally, so that the lens 40 approaches or moves away from the preset light source 70, achieving the purpose of adjustable position of the lens 40, thereby realizing the technical effects of flexible adjustment of the beam angle and cost reduction. Furthermore, it solves the technical problem that the beam angles of most spotlights on the market are fixed. In actual installation and use scenarios, only a fixed-sized illumination range can be generated. When users need to adjust the illumination range, they can only change the installation height or select other spotlights with different beam angles. However, changing the installation height is often limited by space and cannot be implemented; selecting other spotlights with different beam angles will increase the additional commissioning cost or the cost of replacing the lamps.

[0079] Furthermore, two opposing limiting grooves 102 are formed in the moving platform 10 along its radial direction and near the edge side. It can be understood that by respectively arranging the limiting grooves 102 on the opposite sides of the moving platform 10, a good limiting and fixing effect can be achieved. At the same time, a good limiting and matching effect with other components can also be realized, so as to enable the moving platform 10 to move directionally in the vertical direction. Preferably, the limiting groove 102 is U-shaped, which can achieve good limiting and clamping effects.

[0080] Furthermore, a baffle 50 is provided at the bottom of the moving platform 10 on the side close to the adjusting member 20 and used to limit and block the over-travel of the adjusting member 20. It can be understood that by providing the baffle 50, a good limiting and blocking effect on the adjusting member 20 can be achieved, thereby preventing the situation of over-travel of the adjusting member 20 due to misoperation. Preferably, one end of the baffle 50 is inserted into the moving platform 10, and the other end is connected to the bottom of the extension portion 101 through a second connecting member 180, which can achieve a good assembly effect and at the same time an easy disassembly and assembly effect. Among them, the second connecting member 180 includes but is not limited to screws or bolts, which can achieve an easy operation effect and at the same time ensure a good tightening force. More preferably, the baffle 50 is in an L shape, which can achieve an easy connection effect.

[0081] Furthermore, a plurality of racks 1011 are horizontally arranged on the extension portion 101 and close to the adjusting component 20, and a gear structure 201 meshingly connected with the plurality of racks 1011 is arranged on the adjusting component 20 and along its axial direction;

[0082] The length of the gear structure 201 is not less than the length of the rack 1011. It is understandable that by adopting the meshing mode of the gear and the rack 1011, it is possible to achieve the effect of easy assembly and accurate position adjustment; at the same time, the length of the gear structure 201 is not less than the length of the rack 1011, which can ensure sufficient contact between the gear and the rack 1011, thereby ensuring a good adjustment effect, thereby avoiding the occurrence of gear slippage, and reducing the resistance during adjustment.

[0083] Furthermore, an adjustment hole 202 is provided at one end of the adjustment component 20, and a plurality of marks 203 are preset on one side of the adjustment hole 202. It is understandable that by providing the adjustment hole 202, it is possible to facilitate insertion, thereby achieving the effect of adjusting the position of the adjustment component 20; at the same time, a plurality of marks 203 are provided on one side of the adjustment hole 202, which can achieve a good fixed angle adjustment effect. Among them, the end face of the adjustment rod is marked with a plurality of marks 203, and the marks 203 may include but are not limited to: values ​​40, 60, 80, and when the corresponding values ​​are aligned with the pointer above them, they represent the beam angle at this position. Preferably, the shape of the adjustment hole 202 is a rectangle or a polygon. The effect of easy adjustment can be achieved.

[0084] Furthermore, a plurality of limit buckles 301 are evenly arranged on the top of the lens bracket 30 along its circumference, and the engaging ends of the limit buckles 301 face one side of the lens 40;

[0085] Among them, the diameter formed by the engagement ends of the plurality of limit buckles 301 is smaller than the diameter of the outer edge of the lens 40. It can be understood that by providing a plurality of limit buckles 301 on the top of the lens holder 30, the lens 40 can be limitedly engaged in the lens holder 30, thereby preventing it from being displaced, thereby affecting the accuracy of the light beam adjustment; at the same time, the diameter formed by the engagement ends of the plurality of limit buckles 301 is smaller than the diameter of the outer edge of the lens 40, which can ensure that the lens 40 will not be separated from the fixed state of the lens holder 30 when the limit buckle 301 is not moved, thereby ensuring a stable assembly effect.

It can be understood that by disposing the lamp base 60 inside the lamp body 90, a good assembly effect can be achieved. At the same time, at least one second limiting slideway is disposed on the inner wall of the lamp body 90 in the vertical direction, which can achieve a good limiting effect, so that the degree of freedom of the lamp base 60 is limited to move in the vertical direction.

[0092] Further, a through hole 901 for assembling the adjusting component 20 is formed on one side of the lamp body 90, and a cover body 100 is covered on the through hole 901. The cover body 100 is detachably connected to the lamp body 90. It can be understood that by providing the through hole 901 on the side wall of the lamp body 90, a good assembling and adjusting effect of the adjusting component 20 can be achieved; at the same time, by covering the cover body 100 on the through hole 901, the effect of protecting one end of the adjusting component 20 can be achieved. Moreover, by adopting a detachable connection method between the cover body 100 and the lamp body 90, the effect of easy disassembly and assembly can be achieved, and thus the effect of easy replacement can be achieved. Preferably, the cover body 100 can be a silica gel cover, which can ensure a good covering effect.
