Description

Technical Field

[0001] This utility model relates to the field of LED wall washer technology, and in particular to an LED illumination lamp with a flexible adjustable projection angle. Background Technology

[0002] In existing LED wall washer spotlight designs, adjusting the beam angle mostly relies on adjusting the oscillation of the LED light source itself. While this method can adjust the beam angle to some extent, it often suffers from limited adjustment range and inconvenient operation.

[0003] For example, Chinese patent CN202022276469.1 discloses an integrated swinging LED wall washer light, including an LED light source, a heat sink module for dissipating heat from the LED light source, a middle ring installed in conjunction with the heat sink module, an outer ring fixed to the ceiling or other location, and an anti-glare cover for preventing glare from the LED light source. The mounting end of the LED light source 1 is equipped with a light source bracket, and a lens is provided at the light output end of the LED light source corresponding to the light source bracket. The mounting end of the middle ring is fitted onto the outside of the heat sink module and is rotatably installed with the heat sink module via pins. Screws are installed on opposite sides of the outer ring to fix it to the ceiling. The outer ring is fixed to the ceiling or other installation location via the springs. The end of the middle ring is installed with the outer ring via a positioning bead. After the middle ring is fitted onto the outside of the heat sink module, it is rotatably installed with the heat sink module via pins, facilitating the swinging adjustment of the LED light source within the middle ring to adjust the angle of the projected light according to usage, thus achieving angle adjustment for the wall washer light. However, the projection angle adjustment of such integrated swing LED wall washer lights is not flexible and convenient enough. After the original fixed projection angle is changed again, it may be necessary to disassemble the lights on the ceiling or other installation locations before adjustment can be made, which is not convenient to operate.

[0012] Furthermore, several of the aforementioned tightening elastic barbs are arranged around the lens body on the inner wall of the light-concentrating cover.

[0013] Furthermore, the inner wall of the focusing cover is provided with a mounting groove corresponding to the position of the tightening elastic barb, which is used to install the tightening elastic barb and allows the tightening elastic barb to undergo elastic deformation and swing.

[0016] Furthermore, the outer wall of the spherical cover is connected to the inner wall of the inner lampshade by means of a hook limiting member for omnidirectional rotation and swing; a plurality of hook limiting members are evenly distributed on the inner wall of the inner lampshade.

[0017] Furthermore, the outer wall of the inner lamp cover is provided with an elastic inverted hook; the lower inner wall of the radiator housing is provided with a hook groove that matches the elastic inverted hook; the elastic inverted hook has a push-pressing opening on the side opposite to the lower inner wall of the radiator housing.

[0032] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0033] like Figures 1 to 7 As shown, an LED illumination lamp with a flexible adjustable projection angle includes a heat sink housing 1 and an LED light source 2, an inner lampshade 3, and a lens assembly 4 disposed within the heat sink housing 1. The inner lampshade 3 houses the LED light source 2 and is connected within the heat sink housing 1; the lens assembly 4 is pivotally connected within the inner lampshade 3, corresponding to the position of the LED light source 2, and its position can be adjusted relative to the inner lampshade 3 to regulate the light projection angle of the LED light source 2.

[0034] This LED illumination lamp with flexible adjustable projection angle combines a heat sink housing 1, an LED light source 2, an inner lampshade 3, and a lens assembly 4. The lens assembly 4 is oscillatingly connected inside the inner lampshade 3, allowing the projection direction of the LED light source 2 to be changed simply by oscillating the position of the lens assembly 4. This design not only achieves flexible adjustment of the light projection angle, but also offers a wider range of adjustment compared to the oscillating adjustment method of the LED light source 2 in existing technologies. Moreover, the adjustment process is easier and more intuitive, allowing users to achieve precise adjustment of the light projection angle through simple operation, greatly improving user experience and satisfaction. It can achieve the desired light angle effect and is suitable for various lighting scenarios that require flexible adjustment of the light projection angle, such as exhibition halls, galleries, and home decoration, providing designers and users with more creative space and possibilities.

[0035] Preferably, the lens assembly 4 includes a lens body 41 and a condenser 42; the lens body 41 is fitted and secured within the condenser 42; the condenser 42 is pivotally connected within the inner lampshade 3. The lens assembly 4 is formed by designing the lens body 41 and the condenser 42. The lens body 41 is the core component of the lens assembly 4, responsible for the refraction and focusing of light. It is typically made of transparent material and has a specific radius of curvature and shape to achieve the desired optical effect. The fitted lens body 41 within the condenser 42 means that there is a precise dimensional match and positioning between the lens body 41 and the condenser 42, ensuring that light can propagate along the designed path to better project light at the designed light projection angle. This not only improves light utilization efficiency but also enhances the controllability and flexibility of the beam, meeting various complex application requirements.

[0036] To ensure stable installation of the lens body 41 within the condenser 42, and for ease of disassembly, assembly, replacement, and maintenance, the lower end of the lens body 41 has a protruding edge 411. The condenser 42 has an edge-fitting groove 423 that fits and engages with the protruding edge 411. Specifically, the edge-fitting groove 423 is located within the lower end of the condenser 42. The edge-fitting groove 423 is a slot structure for accommodating the protruding edge 411, effectively positioning it in the correct position. Furthermore, the lower end of the condenser 42 has a tightening elastic barb 424 located above the edge-fitting groove 423. The tightening elastic barb 424 has good elastic deformation and recovery capabilities, achieving reliable fixation of the protruding edge 411. When the protruding edge 411 slides past the tightening elastic barb 424 and engages with the edge engaging groove 423, the tightening elastic barb 424 presses against the upper end face of the protruding edge 411 to fix the protruding edge 411 in the edge engaging groove 423. By combining the protruding edge 411, the edge engaging groove 423, and the tightening elastic barb 424, when the protruding edge 411 is engaged with the edge engaging groove 423, the tightening elastic barb 424 is elastic and can deform to allow the protruding edge 411 to pass through. After the protruding edge 411 is in place, it returns to its original shape and presses against the protruding edge 411, thus achieving stable installation of the lens body 41 inside the condenser 42. Compared with screws and other installation methods, it is easier to install and disassemble.

[0037] To further enhance the stability of the lens body 41 within the condenser cover 42 and prevent it from easily loosening, several of the aforementioned tightening elastic barbs 424 are arranged around the lens body on the inner wall of the condenser cover 42. Depending on the requirements, the number of tightening elastic barbs 424 is preferably 3, 4, 5, 6, 7, or 8, resulting in better connection stability. Of course, in another embodiment, with a reasonable structural design, the number of tightening elastic barbs 424 can also be 1 or 2.

[0038] Preferably, to ensure the elastic buckle 424 has good elastic deformation space and facilitates the assembly and disassembly of the lens body 41, the inner wall of the condenser cover 42 is provided with a mounting groove 425 corresponding to the position of the elastic buckle 424 for mounting the elastic buckle 424 and allowing the elastic buckle 424 to elastically deform and swing. By designing the mounting groove 425, when it is necessary to disassemble the lens body 41, pressing the elastic buckle 424 allows it to deform and swing elastically within the mounting groove 425 due to its good elastic deformation and recovery ability, thus facilitating the disassembly of the lens body 41.

[0039] In this embodiment, the condenser 42 is omnidirectionally rotatable and swings within the inner lampshade 3. The connection between the condenser 42 and the inner lampshade 3 allows the condenser 42 to rotate freely within the inner lampshade 3, similar to a sphere that can roll and rotate within it. The lens 41 can rotate and swing omnidirectionally with the condenser 42 within the space of the inner lampshade 3 to adjust the angle of light projection from the LED light source 2, significantly improving the flexibility and functionality of the LED spotlight and enabling it to better adapt to lighting needs with different projection angles. In another embodiment, for the swingable connection between the condenser 42 and the inner lampshade 3, a pivot can be provided on the outer wall of the condenser 42, and a corresponding locking hole or groove can be provided on the inner wall of the inner lampshade 3 to achieve the swingable connection between the condenser 42 and the inner lampshade 3.

[0040] In this embodiment, the light-concentrating cover 42 includes a spherical cover 421 and a cylindrical cover 422; the lower end of the spherical cover 421 is connected to the upper end of the cylindrical cover 422, and their inner cavities are connected; the lens body 41 is fitted and mounted inside the spherical cover 421; the outer wall of the spherical cover 421 is omnidirectionally rotatable and swing-connected to the inner wall of the inner lamp cover 3. By setting the spherical cover 421 and the cylindrical cover 422 to form the light-concentrating cover 42, the spherical cover 421 is used to achieve stable installation of the lens body 41 and adjustment of the projection angle in multiple directions, while the cylindrical cover 422 can better guide and project light to achieve the required light projection angle.

[0041] The outer wall of the spherical cover 421 is connected to the inner wall of the inner lampshade 3 via hook-and-lock device 6 for omnidirectional rotation. Several hook-and-lock devices 6 are evenly distributed on the inner wall of the inner lampshade 3. By restricting the spherical cover 421 within the inner lampshade 3 using these hook-and-lock devices 6, the spherical cover 421 can rotate omnidirectionally within the inner lampshade 3, allowing for adjustment of the lens body 41's position at multiple angles to adjust the light projection direction and achieve the desired light projection angle.

[0042] Specifically, the hook limiting member 6 includes an upper hook portion 61 and a spherical fitting portion connected to the upper hook portion 61. The upper hook portion 61 is used to restrict the spherical cover body 421 from detaching from the inner lamp cover 3, and the spherical fitting portion 62 can better achieve omnidirectional rotation within the inner lamp cover 3.

[0043] In this embodiment, the outer wall of the inner lampshade 3 is provided with an elastic inverted hook 5, which has good elastic deformation and recovery ability; the lower inner wall of the radiator housing 1 is provided with a hook groove 11 that is adapted to the elastic inverted hook 5. By setting the elastic inverted hook 5 and the hook groove 11 to cooperate, the inner lampshade 3 is stably installed in the lower end of the radiator housing 1, and the outer wall of the inner lampshade 3 is detachably connected to the lower inner wall of the radiator housing 1. The structure is simple and easy to assemble and disassemble.

[0044] To facilitate the removal of the inner lamp cover 3, the elastic hook 5 has a pressing slot 51 on one side of the inner wall of the lower end of the radiator housing 1. With the pressing slot 51 on the elastic hook 5, when it is necessary to remove the inner lamp cover 3, a finger or tool is inserted into the pressing slot to press the elastic hook 5. The elastic hook 5 deforms, making it easy to remove the inner lamp cover 3 from the lower end of the radiator housing 1.

[0045] In this embodiment, an outer lamp cover 7 is fitted and fastened to the lower end of the heat sink housing 1. The outer lamp cover 7 can further enhance the focusing effect of the LED illumination lamp, achieving a better lighting effect. The outer lamp cover 7 and the lower end of the heat sink housing 1 can be detachably connected by a snap-fit ​​or threaded connection.

[0046] In summary, this utility model embodiment provides an LED illumination lamp with a flexible adjustable projection angle, which has the following advantages:

[0047] This LED illumination lamp with flexible adjustable projection angle combines a heat sink housing 1, an LED light source 2, an inner lampshade 3, and a lens assembly 4. The lens assembly 4 is oscillatingly connected within the inner lampshade 3, allowing the projection direction of the LED light source 2 to be changed simply by oscillating the lens assembly 4. This design not only achieves flexible adjustment of the light projection angle, but also offers a wider range of adjustment compared to existing oscillating methods of adjusting the LED light source 2. Furthermore, the adjustment process is easier and more intuitive, allowing users to precisely adjust the light projection angle with simple operations, greatly enhancing user experience and satisfaction. It can achieve the desired light angle effect and is suitable for various lighting scenarios requiring flexible light projection angle adjustment, such as exhibition halls, galleries, and home decoration, providing designers and users with more creative space and possibilities.

[0048] Second, by connecting the inner lampshade 3 and the lens assembly 4, the projection angle of the light can be changed. Compared with the existing design, it uses fewer parts and has a relatively lower cost.

[0049] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of this application, and these improvements and substitutions should also be considered within the scope of protection of this application.
