Description

Technical Field

[0001] This utility model relates to the technical field of downlights, and more particularly to a downlight with a replaceable faceplate. Background Technology

[0002] A downlight is a recessed lighting fixture, typically installed within a ceiling or wall, providing uniform, glare-free ambient light. The reflector is a component of the downlight and prevents dust, insects, and other contaminants from entering, thus extending the fixture's lifespan.

[0003] During the use of downlights, the lampshade will gradually oxidize and yellow over time. At this point, the bulb may not have reached the point where it needs to be replaced, but the yellowing of the lampshade will still make the light from the downlight dimmer, especially in places like kitchens where the lampshade is more prone to oxidation, the material becomes brittle and cracks, and there is a risk of fragments falling off. In this case, the lampshade of the downlight needs to be replaced. However, most existing downlights have the lampshade and the outer shell as a single unit, which means that the entire downlight needs to be replaced, which increases the cost of using the downlight. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the above-mentioned technologies.

[0005] Therefore, one objective of this utility model is to provide a downlight with a replaceable mask. When the downlight mask becomes brittle due to oxidation and yellowing, the mask can be replaced separately instead of replacing the entire downlight, thus reducing the cost of use.

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0023] The following description, with reference to the accompanying drawings, describes an embodiment of the present invention: a downlight with a replaceable face mask.

[0024] like Figures 1-5 As shown in the figure, a downlight with a replaceable mask according to an embodiment of the present invention includes: a body 1, a mask 2 and a replacement mechanism 3.

[0025] The mask 2 is installed on the inner wall of the body 1. The replacement mechanism 3 includes a movable ring 31, two sets of locking components 32 and multiple sets of reset components 33. The movable ring 31 is installed on the inner wall of the body 1, the two sets of locking components 32 are respectively installed on the inner wall of the body 1, and the multiple sets of reset components 33 are respectively installed at the bottom of the movable ring 31.

[0026] The main body 1 includes a downlight housing 11 and a lamp tube 12.

[0027] The lamp tube 12 is installed on the inner wall of the downlight housing 11.

[0028] The card slot component 32 includes a card block 321.

[0029] The card block 321 is set on the outer wall of the mask 2, the upper wall of the downlight housing 11 is provided with an installation groove 322, the inner wall of the downlight housing 11 is provided with a sliding groove 323, and the inner wall of the downlight housing 11 is provided with a fixing groove 324.

[0030] It should be noted that the width of the mounting groove 322 matches the width of the locking block 321, the height of the sliding groove 323 matches the height of the locking block 321, and the width of the fixing groove 324 matches the width of the locking block 321. This ensures that the locking block 321 can enter the mounting groove 322, the sliding groove 323, and the fixing groove 324.

[0031] The reset assembly 33 includes a telescopic post 331, a limiting strip 332, a limiting groove 335, and a spring 336.

[0032] The telescopic column 331 is located at the bottom of the movable ring 31. The side wall of the limiting strip 332 is connected to the outer wall of the telescopic column 331. The storage column 333 is sleeved on the outer wall of the telescopic column 331. The upper end of the storage column 333 is provided with a storage groove 334 and a limiting groove 335. One end of the spring 336 is connected to the bottom wall of the telescopic column 331, and the other end of the spring 336 is connected to the inner wall of the storage groove 334.

[0033] It should be noted that the outer wall dimensions of the telescopic column 331 match the inner wall dimensions of the storage groove 334, which allows the telescopic column 331 to enter the storage groove 334. The outer wall dimensions of the limiting strip 332 match the inner wall dimensions of the limiting groove 335, which allows the limiting strip 332 to enter the limiting groove 335 and ensures that the telescopic column 331 will not rotate inside the storage groove 334.

[0034] Specifically, when it is necessary to replace the face mask 2, the operator presses the face mask 2 with their hand. The face mask 2 compresses the telescopic column 331, thereby compressing the spring 336 inside the storage groove 334. The spring 336 retracts, and then the locking block 321 moves from the upper part to the bottom of the fixing groove 324. Then, the face mask 2 is rotated so that the locking block 321 slides along the sliding groove 323 until it contacts the inner wall of the mounting groove 322. Then, the operator releases their hand from pressing the face mask 2 and removes the face mask 2 along the mounting groove 322. Then, a new face mask 2 is replaced. The installation is then completed by repeating the above operation in reverse.

[0035] A heat dissipation component 4 is provided at the bottom of the main body 1.

[0036] In one embodiment of this application, such as Figure 4 As shown, the heat dissipation component 4 includes a heat-conducting plate 41, a heat dissipation ring 42, and multiple heat dissipation pillars 43.

[0037] Understandably, multiple heat dissipation pillars 43 can increase the contact area between the heat dissipation ring 42 and the air.

[0038] Specifically, when the downlight is turned on, the lamp tube 12 generates heat, which is transferred to the heat dissipation ring 42 through the heat conduction plate 41, and then dissipated to the outside of the downlight through multiple heat dissipation columns 43.

[0039] In summary, when using downlights, if the downlight cover becomes yellowed and brittle due to oxidation, the cover can be replaced individually instead of replacing the entire downlight, thus reducing usage costs.
