[0002] High-domed lights, widely used in industrial plants, large warehouses, stadiums, exhibition centers, and other large spaces, play a crucial role in providing ample, uniform, and high-quality lighting for these large areas. In these locations, the significant ceiling height places high demands on the lighting effect, ease of installation and maintenance, and flexibility of use of high-domed lights.

[0003] Different locations have different requirements for the lighting angle of dome lights. For example, in sports stadiums, the illumination angle of dome lights needs to be adjusted to provide the best lighting effect depending on the type of event and the layout of the venue; in warehouses, the angle of the lights also needs to be flexibly adjusted according to the storage location and height of the goods. However, existing dome lights have many problems with angle adjustment. Some dome lights use a fixed installation method and cannot be adjusted in angle; once installed, the lighting angle is fixed and cannot meet diverse usage needs. Other dome lights, although they have angle adjustment functions, have complex adjustment structures and are inconvenient to operate. Summary of the Invention

[0020] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but should not be used to limit the scope of this utility model. Example

[0021] Combination Figure 1 , Figure 2 and Figure 3 As shown, the high-ceiling lamp of this embodiment, which is easy to disassemble and adjust, includes a lamp holder 1. A lamp plate 2 is provided on the front of the lamp holder 1. A lamp cover 3 is provided on the outer side of the lamp plate 2. A plurality of LED beads 4 are arranged in a spiral at equal intervals on the lamp plate 2. A spiral lens 5 corresponding to the LED beads 4 is provided on the lamp cover 3. The outer periphery of the lens 5 is provided with a disassembly and assembly mechanism 6 for installing or removing the lens 5 on the lamp holder 1 in a cross shape. Rotating the lens 5 on the lamp holder 1 can adjust the angle of the light of the LED beads 4.

[0022] The lamp holder 1 provides a mounting position for other components. The lamp cover 3 covers the outside of the lamp panel 2, protecting the lamp panel 2 and the LED beads 4. It also works with the lens 5 to adjust the direction and range of light illumination. The LED beads 4 are arranged in a spiral pattern at equal intervals on the lamp panel 2. The spiral lens 5 is mounted on the lamp cover 3, corresponding to the LED beads 4. The disassembly / removal mechanism 6 is arranged in a cross shape around the lens 5, facilitating the installation and removal of the lens 5 from the lamp holder 1.

[0023] When the high-ceiling light is connected to the power supply, the current flows through the lamp panel 2, causing the spirally arranged, equidistant LED beads 4 to emit light, thus producing illumination. By rotating the lens 5 on the lamp holder 1, since the lens 5 corresponds to the LED beads 4 and has specific optical characteristics, rotating the lens 5 changes its refraction and scattering of the light emitted by the LED beads 4, thereby adjusting the angle of the light emitted by the LED beads 4 to meet the needs of light direction and range in different scenarios. Using the cross-shaped disassembly mechanism 6 set on the outer periphery of the lens 5, the operator can easily and quickly install or remove the lens 5 on the lamp holder 1 by applying a specific force to the disassembly mechanism 6, facilitating cleaning, replacement, or maintenance of the lens 5.

[0024] Combination Figure 2 , Figure 4 and Figure 5 As shown, the disassembly and assembly mechanism 6 includes a buckle 61 mounted on the lamp holder 1, and a slot 62 on the lens 5 that matches the buckle 61. The buckle 61 is fixedly mounted on the lamp holder 1. It has a certain degree of elasticity and a locking structure, enabling it to fit tightly with corresponding components to ensure the stability and reliability of the connection. The slot 62 is located on the lens 5, and its shape and size match the buckle 61. The slot 62 is the corresponding mating part of the buckle 61, allowing the buckle 61 to be accurately inserted, thereby achieving a stable connection between the lens 5 and the lamp holder 1. The slot 62 ensures a moderate mating gap with the buckle 61, guaranteeing both the strength of the connection and facilitating disassembly when needed.

[0025] When lens 5 needs to be installed onto lamp holder 1, the operator aligns the slot 62 on lens 5 with the buckle 61 on lamp holder 1, and then applies a certain amount of pressure to cause buckle 61 to elastically deform and smoothly embed into slot 62. After buckle 61 is fully embedded into slot 62, buckle 61 returns to its original shape, and its own locking structure locks tightly against the inner wall of slot 62, thereby firmly fixing lens 5 onto lamp holder 1, ensuring the relative stability of the position of lens 5 and LED beads 4, and guaranteeing normal light refraction and adjustment functions.

[0026] When lens 5 needs to be disassembled, the clip 61, due to its elasticity, will deform elastically again under external force, thus disengaging from the slot 62. Once clip 61 is completely disengaged from slot 62, lens 5 can be removed from lamp holder 1, completing the disassembly operation.

[0027] Specifically, the buckle 61 includes a fixing part 611 that is bolted to the lamp holder 1, a snap-fit ​​wedge 612 connected to the inner side of the fixing part 611, a pressing gap 613 between the snap-fit ​​wedge 612 and the fixing part 611, a bending part 614 connected to the top of the snap-fit ​​wedge 612, and a pressing plate 615 connected to the top of the bending part 614.

[0028] Specifically, the fixing part 611 is fixedly mounted on the lamp holder 1 by bolts, and is the fixed part connecting the buckle 61 and the lamp holder 1. The snap-fit ​​wedge 612 is connected to the inside of the fixing part 611 to realize the snap-fit ​​function of the buckle 61. The pressing gap 613 is set between the snap-fit ​​wedge 612 and the fixing part 611. This gap provides space for the pressing operation, so that the snap-fit ​​wedge 612 can have a certain amount of movement when pressed by external force. The bending part 614 is connected to the top of the snap-fit ​​wedge 612. The pressing plate 615 is connected to the top of the bending part 614, which is the part where the operator directly applies force. By pressing the pressing plate 615, the entire buckle 61 can produce a corresponding action.

[0029] When it is necessary to operate the latch 61, such as unlocking or fastening, the operator presses the pressing plate 615 by hand. Since the pressing plate 615 is connected to the top of the bent portion 614, which in turn is connected to the top of the fastening wedge 612, the pressure on the pressing plate 615 is transmitted to the fastening wedge 612 through the bent portion 614. A pressing gap 613 is provided between the fastening wedge 612 and the fixing portion 611, allowing the fastening wedge 612 to move a certain distance towards the fixing portion 611 when pressure is applied. Through this movement of the fastening wedge 612, the unlocking or fastening action between the latch 61 and the slot 62 of the lens 5 can be achieved. When unlocking, press the pressing plate 615 to move the latching wedge 612, disengaging it from the slot 62 of the lens 5; when latching, bring the buckle 61 close to the slot 62 of the lens 5, press the pressing plate 615 to move the latching wedge 612 to the appropriate position, and then release the pressing plate 615 to return the latching wedge 612 to its original position to achieve latching.

[0030] like Figure 3 As shown, the cross-section of lens 5 is an arc-shaped structure, and the LED bead 4 is disposed inside lens 5. The LED bead 4 serves as the light source and works closely with lens 5. The arc-shaped structure of lens 5 surrounds the LED bead 4, and together they form a complete optical system to achieve a specific lighting effect.

[0031] like Figure 1 , Figure 2 and Figure 3As shown, when the LED bead 4 is close to the inner ring of the lens 5, the light illumination angle is an acute angle. According to the structural settings in this embodiment, the light illumination angle is adjusted to 60 degrees. Specifically, when the high-ceiling light is connected to the power supply, the LED bead 4 starts working and emits light. At this time, the LED bead 4 emits light into the surrounding space. Because the refractive index of the lens 5 is different from that of the surrounding medium, such as air, when the light emitted by the LED bead 4 enters the lens 5 material from the medium where the LED bead 4 is located (usually the encapsulation material) and then exits from the lens 5 material into the air, a double refraction phenomenon occurs. According to Snell's law of refraction, at the interface between two media with different refractive indices, the angle of incidence and the angle of refraction satisfy a specific relationship, namely... n 1sin θ 1= n 2sin θ 2 of which n 1. n 2 represents the refractive index of the two media, θ 1 is the angle of incidence. θ 2 is the angle of refraction.

[0032] When the LED bead 4 approaches the inner side of the cross-section of the lens 5, the light emitted from the LED bead 4 is directed towards the inner surface of the cross-section of the lens 5. After refraction by the lens 5, most of the light propagates in a relatively concentrated direction. Through precise optical design and calculation, in this case, the angle corresponding to the illumination range formed by the refracted light is approximately 60 degrees, resulting in a good light-focusing effect.

[0033] When the cross-section of the lens 5 is centered at the LED bead 4, the light beam is at a 90-degree angle. Specifically, when the LED bead 4 is centered at the cross-section of the lens 5, the light emitted from the LED bead 4 is directed towards various parts of the lens 5. After refraction by the lens 5, the propagation range of the light in the horizontal and vertical directions reaches a specific equilibrium state. Through precise optical design and calculation, under these conditions, the angle corresponding to the maximum illumination range formed by the refracted light is approximately 90 degrees, while also possessing a certain focusing effect and illumination range.

[0034] When the LED bead 4 is close to the outer ring of the lens 5, the light illumination angle is obtuse. Specifically, when the LED bead 4 is close to the outer side of the cross-section of the lens 5, the light emitted from the LED bead 4 is directed towards the edge area of ​​the lens 5. Compared to when the LED bead 4 is in other positions, the angle at which the light enters the surface of the lens 5 is larger. After refraction by the lens 5, the light is scattered more extensively during propagation. In this embodiment, the illumination range formed by the refracted light corresponds to an angle of approximately 110 degrees. Example

[0035] Compared to Example 1, in this example, as Figure 1 and Figure 2 As shown, the lamp panel 2 has graduations for adjusting the angle, and the lens 5 has positioning marks 7 for adjusting the angle. These graduations are distributed on the lamp panel 2 in a specific manner, possibly evenly or non-uniformly arranged along an axis or a specific area, to provide a precise reference for angle adjustment. Positioning marks 7 are also provided on the lens 5. These positioning marks 7 also exist in a specific form on the lens 5, used to coordinate with the graduations on the lamp panel 2 when adjusting the angle to achieve accurate positioning.

[0036] During angle adjustment, the scale on the lamp panel 2 and the positioning mark 7 on the lens 5 work together. The operator determines the current angle of the lens 5 by observing the position of the positioning mark 7 relative to the scale on the lamp panel 2. When the angle of the lens 5 needs adjustment, it is moved according to the target angle until its positioning mark 7 aligns with the corresponding scale position on the lamp panel 2, thus achieving precise angle adjustment. This makes the angle adjustment process more intuitive and accurate, allowing the operator to quickly adjust the lens 5 to the desired angle.

[0037] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
