Description

Technical Field

[0001] This utility model relates to the technical field of lighting fixtures, and in particular to the technical field of an LED light with a replaceable frame. Background Technology

[0002] LED lights, due to their energy-saving, environmentally friendly, and long lifespan advantages, are widely used in various lighting applications. Existing LED light fixtures typically use screws or adhesive to fix the lampshade or frame to the main body. While this method provides a secure connection, it also has significant drawbacks: when users need to replace the lampshade to adapt to changes in the scene (such as altering the lighting effect, style, or due to lampshade damage), the process is very cumbersome, requiring tools to remove the screws or damaging the adhesive layer, making replacement inconvenient and easily damaging the main body of the light fixture. Furthermore, the single, fixed lampshade design cannot meet users' needs for diverse lighting effects and personalized decoration.

[0003] Therefore, there is an urgent need for an LED light that allows for easy and quick replacement of the lampshade or frame, in order to improve the product's practicality and user experience. Utility Model Content

[0004] The purpose of this invention is to solve the problems of cumbersome lampshade replacement, the need for tools, and the inability to meet the diverse needs of users in the existing technology. It proposes an LED lamp with replaceable frame, which has a simple structure, is easy to operate, can quickly replace the lampshade, has a reliable connection, and can provide a variety of light options.

[0005] To achieve the above objectives, this utility model proposes an LED light with a replaceable frame, comprising an LED light body and a lampshade. The outer wall of the LED light body's outer shell is provided with at least two outwardly protruding inverted L-shaped fasteners. Each inverted L-shaped fastener includes a vertical portion connected to the outer wall of the outer shell and a horizontal portion extending counterclockwise from the upper end of the vertical portion, thereby forming a groove below the horizontal portion. The inner wall of the lampshade is provided with snap-fit ​​protrusions that match the number and position of the inverted L-shaped fasteners. The cross-section of the snap-fit ​​protrusions is a right-angled trapezoid with its inclined surface facing downwards. The upper part of the inner wall of the lampshade also extends inwards with a ring-shaped or partially ring-shaped limiting platform. The lampshade is guided and engaged with the slot of the inverted L-shaped fastener through the inclined surface of its snap-fit ​​protrusions, and the snap-fit ​​protrusions and slots are engaged by rotation. At this time, the limiting platform is engaged with the top surface of the LED lamp body to achieve axial limiting. When disassembling, the lampshade is rotated in the opposite direction to disengage the snap-fit ​​protrusions from the slots, and then the lampshade is moved upwards to achieve separation.

[0006] Furthermore, the rotation is clockwise, and the reverse rotation is counterclockwise.

[0007] Furthermore, the lampshade is a conventional annular frame or a grille lampshade, with several elongated through holes on its circumferential sidewalls and / or top surface. The limiting platform of the grille lampshade can be a complete ring or a partial ring (e.g., a semi-circle). Users can choose to install a conventional annular frame with a simple structure and low cost, or a grille lampshade with special lighting effects and aesthetic functions, as needed, to achieve different optical effects and appearances.

[0008] Furthermore, the LED lamp body is equipped with components such as an LED lamp board, a power module, and a control module. Its outer shell is equipped with a hemispherical infrared sensor head, which enables the LED lamp to have a human body sensing function, so that the lamp automatically turns on when a person comes and automatically turns off when a person leaves, making it more intelligent and energy-saving.

[0009] Furthermore, the inverted L-shaped buckle is integrally formed with the outer shell of the LED lamp body, and the snap-fit ​​protrusion and limiting platform are integrally formed with the lampshade, ensuring the strength of the structure and the convenience of production.

[0010] Furthermore, there are four inverted L-shaped fasteners, evenly distributed along the circumference; the distance between two adjacent inverted L-shaped fasteners is slightly greater than the lateral dimension of the latching protrusion. This design ensures that the latching protrusion has sufficient space to rotate into and out of the slot when the lampshade rotates, enabling smooth installation and removal.

[0011] The beneficial effects of this utility model are: 1. Quick Replacement and Precise Positioning: Utilizing a unique inverted L-shaped latch and a rotating latch structure with right-angled trapezoidal protrusions, users can install the lampshade without any tools by simply pressing down and rotating, and remove it by rotating in the opposite direction and lifting it up. Replacement is extremely simple and quick. The limiting platform structure ensures that the lampshade fits tightly against the top surface of the LED light body after installation, preventing axial movement, resulting in more precise positioning and greatly improved stability.

[0012] 2. Reliable connection: After engagement, the vertical surface of the right trapezoid and the horizontal part of the inverted L-shaped fastener form a radial limit, and the limiting platform forms an axial limit, ensuring the firmness and stability of the lampshade connection and preventing it from loosening or falling off.

[0013] 3. Versatile Functionality: Users can easily change the lampshade style (such as regular ring frame, full grille, half grille, or other irregular designs) according to personal preferences or different usage environments, thereby achieving flexible changes in lighting effects and decorative style, greatly enhancing the added value of the product and the user experience. The regular ring frame structure is simple and low-cost, while the grille lampshade has special optical effects.

[0014] 4. Simple structure and low cost: The buckle and limiting structure can be easily integrated into production through molds without the need for additional connecting parts. The structure is simple and reliable, and the production cost is low.

[0015] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

[0018] See Figures 1-8This utility model includes an LED lamp body 1 and a lampshade 2. Its features include: at least two outwardly protruding inverted L-shaped fasteners 11 on the outer wall of the LED lamp body 1; each inverted L-shaped fastener 11 includes a vertical portion connected to the outer wall and a horizontal portion extending counterclockwise from the upper end of the vertical portion, thus forming a groove 111 below the horizontal portion; the inner wall of the lampshade 2 is provided with engaging protrusions 21 matching the number and position of the inverted L-shaped fasteners 11, and the cross-section of each engaging protrusion 21 is a right-angled trapezoid. Its inclined surface 211 faces downward; the upper part of the inner wall of the lampshade 2 also has a ring or partially ring-shaped limiting platform 23 extending inward; the lampshade 2 is guided and engaged with the slot 111 of the inverted L-shaped buckle 11 through the inclined surface 211 of its snap-fit ​​protrusion 21, and the snap-fit ​​protrusion 21 and the slot 111 are engaged by rotation. At this time, the limiting platform 23 is fastened to the top surface of the LED lamp body 1 to achieve axial limiting; when disassembling, the snap-fit ​​protrusion 21 is disengaged from the slot 111 by rotating the lampshade 2 in the opposite direction, and the lampshade 2 is moved upward to achieve separation.

[0019] The working process of this utility model: The working process of this utility model of an LED light with a replaceable frame is described in conjunction with the accompanying drawings.

[0020] The LED lamp body 1 contains conventional components such as an LED lamp board, a power module, and a control module. Four evenly distributed inverted L-shaped fasteners 11 are integrally formed on the bottom outer wall of its outer casing. Each inverted L-shaped fastener 11 includes a vertical portion connected to the outer wall of the outer casing and a horizontal portion extending counterclockwise from the upper end of the vertical portion, thus forming a slot 111 below the horizontal portion. A hemispherical infrared sensor 12 is also provided on the outer casing of the LED lamp body 1 for sensing human activity. The distance between two adjacent inverted L-shaped fasteners 11 is slightly larger than the lateral dimension of the latching protrusion 21.

[0021] There are two preferred embodiments of the lampshade 2: one is a semi-grille lampshade (such as...) Figure 1 , Figure 2 , Figure 3 As shown), another type is the conventional ring-shaped frame (such as...). Figure 5 , Figure 6 (As shown). Both types of lampshades 2 have four integrally formed snap-fit ​​protrusions 21 corresponding to the positions of the inverted L-shaped fasteners 11 on their inner walls. The cross-section of each snap-fit ​​protrusion 21 is a right-angled trapezoid, and the structure of its inclined surface 211 is as follows... Figure 4 As shown in the enlarged view, the inclined surface 211 faces downwards. A limiting stage 23 extends inwards from the upper part of the inner wall of the lampshade 2. For a conventional annular frame ( Figure 6 This limiting platform 23 is a complete ring; for the half-grille lampshade ( Figure 3The limiting platform 23 is partially annular (e.g., semi-circular), with the remaining part being open or having grille through holes 22. The circumferential sidewalls and / or top surface of the semi-grille lampshade have multiple elongated through holes 22, forming a grille structure.

[0022] During installation, align the snap-fit ​​protrusion 21 on the lampshade 2 with the top surface of the inverted L-shaped latch 11 on the LED lamp body 1 and push it downwards. The inclined surface 211 of the snap-fit ​​protrusion 21 will first contact the upper end of the horizontal portion of the inverted L-shaped latch 11. As you continue to push downwards, the inclined surface 211 will provide guidance and compression. After the upper surface of the snap-fit ​​protrusion 21 passes the horizontal portion of the inverted L-shaped latch 11, the snap-fit ​​protrusion 21 slides into the slot 111 of the inverted L-shaped latch 11, and at the same time, the limiting platform 23 contacts the top surface of the LED lamp body 1. At this point, you can continue to rotate the lampshade 2 clockwise by a certain angle so that the snap-fit ​​protrusion 21 abuts against the inner wall of the slot 111. At this time, the lampshade 2 is limited in both the radial and axial directions, completing a secure connection.

[0023] When replacement is needed, simply hold the lampshade 2 and rotate it counterclockwise by an angle to allow the locking protrusion 21 to rotate out of the slot 111, freeing it from the restriction of the horizontal part of the inverted L-shaped fastener 11. The lampshade 2 can then be easily removed upwards. It can then be replaced with another conventional ring-shaped frame or half-grille lampshade, etc., to achieve different optical effects and appearances.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. For example, the number of inverted L-shaped fasteners 11 and snap-fit ​​protrusions 21 may be three or five, etc.; the specific shape and extent of the limiting platform 23 may be adapted to the overall shape of the lampshade. The scope of the present invention is defined by the appended claims and their equivalents.

[0025] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
