Description

Technical Field

[0001] This application relates to the field of lighting technology, and in particular to an integrated quick-connect downlight. Background Technology

[0002] LED (Light Emitting Diode) downlights, as a new type of LED lighting source, offer advantages such as energy saving, low carbon footprint, long lifespan, and fast response, making them widely applicable in various scenarios. However, current LED downlight wiring and installation methods still rely on external terminals or junction boxes. During installation, screwdrivers and other tools are required to connect the external power supply line to the internal wiring of the downlight using bolts. This method of connecting the power cord requires external tools, is cumbersome, inefficient, and poses a safety hazard due to loose bolts. Therefore, there is an urgent need for an LED downlight structure that simplifies the wiring process and improves installation efficiency.

[0003] CN206369129U discloses a quick-connect LED downlight, which includes a downlight body and a cover plate. The cover plate is a hollow cylinder and covers the upper end of the downlight body. A groove is provided around the outer wall of the downlight body, and the outer wall of the cover plate is engaged in the groove and slides up and down within the groove. The upper side wall of the cover plate has two wire inlet holes, and a pressure block is provided on each of the left and right sides of the lower end of the wire inlet holes. The lower end of the bottom conductive plate is connected to the downlight body, and the upper end of the bottom conductive plate is connected to the upper conductive plate.

[0004] The quick-wiring LED downlight provided by the above-mentioned utility model requires a rubber gasket ring to limit and fix the cover plate in addition to the sliding cover plate during the wiring operation. This technical solution has limited improvement on the convenience of the wiring operation and still requires the assistance of an external rubber gasket. Utility Model Content

[0006] This application provides an integrated quick-connect downlight, which includes a housing and a circuit board. The housing is cylindrical, and the circuit board is disposed inside the housing. The integrated quick-connect downlight also includes a quick-connect section for connecting an external power cord.

[0007] The quick-connection section includes a connection button, two flow-guiding pressure plates, and two elastic pressure plates. The elastic pressure plates have a deformation portion capable of elastic deformation.

[0008] The two flow guide plates are separated from each other;

[0011] The deformable portions of the two elastic pressure plates abut against the bottom surface of the wiring button.

[0012] When the connection button is pressed, the deformable part moves away from the flow guiding pressure plate. After the pressure on the connection button is released, the deformable part presses against the flow guiding pressure plate.

[0013] The flow guide pressure plate is electrically connected to the circuit board.

[0014] In at least one possible implementation, the quick-connect portion further includes a retaining cap, which is connected to the housing by a snap-fit ​​structure or bolts and forms a limit on the wiring button to prevent the wiring button from disengaging from the quick-connect portion.

[0015] The cover has a button through hole, one end of the wiring button is exposed through the button through hole and can be pressed, and the other end of the wiring button is forked and abuts against the deformed parts of the two elastic pressure plates respectively.

[0021] In at least one possible implementation, the receiving cavity further forms two spaced-apart elastic sheet receiving grooves, the elastic sheet receiving grooves being recessed toward the top surface of the housing, and the elastic pressure strips being able to be inserted into the elastic sheet receiving grooves through the opening of the receiving cavity.

[0022] In at least one possible implementation, a button receiving groove is formed between the two elastic sheet receiving grooves for accommodating a portion of the wiring button, the button receiving groove being recessed towards the top surface of the housing.

[0023] The end of the deformable part overlaps with the projection portion of the button receiving groove in the direction of movement of the wiring button, so that the button receiving groove can limit the deformable part in the direction of movement of the wiring button.

[0024] In at least one possible implementation, button receiving grooves are also formed on both sides of the receiving cavity for accommodating a portion of the wiring button, and the button receiving grooves are recessed towards the top surface of the housing.

[0025] The bottom of the button receiving slot is parallel to the bottom of the button receiving slot.

[0060] Exemplary embodiments of this application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are for teaching those skilled in the art how to implement this application only, and are not intended to exhaustively describe all possible methods of this application, nor to limit the scope of this application.

[0061] This application provides an integrated quick-connect downlight (hereinafter, sometimes simply referred to as a "downlight") to improve the ease of connecting the downlight to an external power cord. For example... Figure 1 and Figure 4 As shown, the integrated quick-connect downlight 100 may include a quick-connect part 110, a housing 120, and a circuit board 130.

[0062] like Figure 1 , Figure 2 and Figure 3 As shown, the quick-connect section 110 is used to connect to the external power cord 200 to supply power to the downlight. The housing 120 can be cylindrical; the term "cylindrical" here is broadly interpreted and can include cylindrical, frustum-shaped, prism-shaped, and truncated pyramidal shapes, etc. The circuit board 130 can be disposed inside the downlight, and a light-emitting element can be disposed on the circuit board 130. The circuit board 130 can be electrically connected to the quick-connect section 110 (including connection via wires, metal plates, plug ports, etc.). Multiple spring clips 140 can be arranged circumferentially around the downlight to limit the downlight at the mounting hole (e.g., downlight mounting hole in a suspended ceiling, ceiling structure, etc.).

[0063] like Figure 2 , Figure 3 As shown, the quick-connect section 110 may include a cover 111, a connection button 112, two flow-guiding pressure plates 113, and two elastic pressure plates 114. The cover 111 can be connected to the housing 120 via a snap-fit ​​structure or bolts and form a limit on the connection button 112 to prevent the connection button 112 from disengaging from the quick-connect section 110. For example, as... Figure 2As shown, the cover 111 can be connected to the housing 120 by two cover screws 1111. A button through hole 1112 can be formed in the middle of the cover 111 for passing through a portion of the wiring button 112.

[0064] The current-guiding pressure plate 113 can be electrically connected to the circuit board 130. For example, in this embodiment, the two current-guiding pressure plates 113 can be connected to the circuit board 130 respectively via wires. The elastic pressure plate 114 can have a deformation portion 1141 capable of elastic deformation; that is, the deformation portion 1141 is the main structure for compression deformation. The current-guiding pressure plate 113 and the elastic pressure plate 114 are used to contact the external power line 200. The two current-guiding pressure plates 113 and the two elastic pressure plates 114 can be separated from each other to avoid short circuits between the live wire and the neutral wire.

[0065] Preferably, an insulating structure may be provided between the two flow guiding pressure plates 113 and between the two elastic pressure plates 114 to enhance the safety of the downlight.

[0066] Furthermore, the flow guide pressure plate 113 and the elastic pressure plate 114 can be arranged one-to-one in the pressing direction of the wiring button 112. The projections of the corresponding flow guide pressure plate 113 and elastic pressure plate 114 in the pressing direction of the wiring button 112 at least partially overlap. The deformable portions 1141 of the two elastic pressure plates 114 can both abut against the bottom surface of the wiring button 112. When the wiring button 112 is pressed, the deformable portions 1141 can move and move away from the flow guide pressure plate 113. After releasing the pressure on the wiring button 112, the deformable portions 1141 can press against the flow guide pressure plate 113.

[0067] One end of the wiring button 112 can be exposed through the button through hole 1112, so that the wiring button 112 can be pressed. The other end of the wiring button 112 can form a forked structure, which can abut against the deformable parts 1141 of the two elastic pressure plates 114 respectively.

[0068] like Figure 2 and Figure 3 As shown, when the connection button 112 is pressed, a gap can be formed between the deformable portion 1141 of the elastic clamping plate 114 and the current-guiding clamping plate 113, allowing the external power cable 200 to extend into this gap. When the connection button 112 is released, the deformable portion 1141 will spring back and clamp the external power cable 200 with the current-guiding clamping plate 113. Pressing the connection button 112 again creates a gap between the deformable portion 1141 and the current-guiding clamping plate 113, allowing the external power cable 200 to be separated from the quick-connect part 110. It can be understood that the deformable portion 1141 continuously presses the external power cable against the current-guiding clamping plate 113, which avoids the risk of poor contact due to loose bolts compared to the traditional bolt-connected power cable method.

[0069] Preferred, such as Figure 3 As shown, the deformable part 1141 can contact the flow guiding pressure plate 113 when the wiring button 112 is not pressed. That is, when the wiring button 112 is not pressed, the bottom surface of the wiring button 112 is flush with one side of the deformable part 1141 that contacts the flow guiding pressure plate 113. This structural feature can maximize the deformation movement of the deformable part 1141, thereby increasing the clamping force of the elastic pressure plate 114 on the external power line 200.

[0070] Preferably, the deformable part 1141 and the bottom surface of the wiring button 112 can form an angle of 30 to 60 degrees, so that the deformation of the deformable part 1141 is smoother when the wiring button 112 is pressed.

[0071] Preferably, the flow guiding pressure plate 113 and the elastic pressure plate 114 can be made of metal. The flow guiding pressure plate 113 can be made of a material with good conductivity, such as copper; the elastic pressure plate 114 can be made of a material with good resilience, such as spring steel.

[0072] Preferably, the wiring button 112 can be made of insulating material. The surface of the wiring button 112 can also be formed with anti-slip texture.

[0073] Preferably, the quick-connect section 110 can be located at the bottom periphery of the housing 120 (in this application, the side facing away from the light-emitting direction of the downlight is considered the bottom of the downlight, and the side emitting light is considered the top of the downlight; in this application, the orientation of the housing and the downlight are described in the same way), and the pressing direction of the connection button 112 can be aligned with the axial direction of the housing 120, while the external power cord 200 can be connected to the quick-connect section 110 approximately radially along the downlight. This structure allows the external power cord 200 to extend approximately radially along the downlight after being connected to it without forming a bend near the connection point. It is understood that in another embodiment, the pressing direction of the connection button 112 can also be aligned with one radial direction of the housing 120, and the external power cord 200 can be connected from the bottom of the downlight.

[0074] Furthermore, such as Figure 6 and Figure 7As shown, the housing 120 may include a wiring mounting portion protruding from its bottom surface to its top surface. The wiring mounting portion may form a receiving cavity 122 for housing at least a portion of the structure of the quick-connect portion 110. The receiving cavity 122 may be open on the bottom surface of the housing 120 and recessed towards the top surface of the housing. The portion of the receiving cavity 122 located radially inward of the housing 120 may form two guide vane through holes 1221. The portion of the guide vane 113 used for contacting the external power line 200 can be inserted into the receiving cavity 122 through the guide vane through holes 1221 to achieve convenient assembly. The guide vane 113 is at least partially disposed outside the receiving cavity 122 for connecting the circuit board 130 via wires.

[0075] Preferably, the circuit board 130 may have notches formed at its edges to allow for the receiving cavity 122.

[0076] Preferred, such as Figure 3 As shown, the portion of the flow guide pressure plate 113 located outside the receiving cavity 122 can be connected to the outer wall of the receiving cavity 122 by bolts.

[0077] The receiving cavity 122 may also form two spaced-apart elastic sheet receiving grooves 1222 for accommodating the elastic pressure piece 114. The elastic sheet receiving grooves 1222 may be recessed into the top surface of the housing 120. The elastic pressure piece 114 can be installed into the elastic sheet receiving groove 1222 through the opening of the receiving cavity 122, thereby making it easier to assemble the quick connector 110.

[0078] A button receiving groove 1223 may also be formed between the two elastic sheet receiving grooves 1222 for accommodating a portion of the wiring button 112 (the middle part of the wiring button). The button receiving groove 1223 may be recessed into the top surface of the housing 120.

[0079] Preferably, the end of the deformable portion 1141 and the projection of the button receiving groove 1223 in the direction of movement of the wiring button 112 can partially overlap, so that the button receiving groove 1223 can limit the deformable portion 1141 in the direction of movement of the wiring button 112. For example, Figure 2 and Figure 8 As shown, the ends of the deformable part 1141 can extend a certain distance to both sides.

[0080] The receiving cavity 122 may also have button receiving sub-grooves 1224 formed on both sides for accommodating a portion of the wiring button 112 (the two sides of the wiring button). The button receiving sub-grooves 1224 are recessed towards the top surface of the housing 120. The bottom of the button receiving sub-grooves 1224 may be parallel to the bottom of the button receiving groove 1223. The end of the deformable portion 1141 and the projection of the button receiving sub-grooves 1224 in the movement direction of the wiring button 112 may partially overlap, so that the button receiving sub-grooves 1224 can limit the deformation portion 1141 in the movement direction of the wiring button 112. For example, as shown... Figure 2 and Figure 8 As shown, the ends of the deformable part 1141 can extend a certain distance to both sides.

[0081] like Figure 7 and Figure 8 As shown, two protruding structures 1225, separated by a button receiving groove 1223, can be formed between the two elastic sheet receiving grooves. The two protruding structures 1225 can isolate the live wire and the neutral wire in the external power cord 200. Screw holes can also be formed on the two protruding structures 1225 to allow the receiving cavity 122 to be screwed into the cover 111.

[0082] Preferably, the downlight can be an LED downlight, that is, one or more light-emitting diodes (LEDs) can be set on the circuit board 130.

[0083] Preferred, such as Figure 4 and Figure 5 As shown, the integrated quick-connect downlight 100 may also include a light diffuser 150, which is disposed inside the housing 120 or at an opening, with the light diffuser 150 positioned relative to the circuit board 130 near the opening of the housing 120. The light diffuser 150 can make the light emitted by the downlight softer and more uniform.

[0084] Preferred, such as Figure 4 and Figure 5 As shown, multiple spring clips 140 are connected to the bottom of the housing 120, and the multiple spring clips 140 can be evenly distributed along the circumference of the integrated quick-connect downlight. For example, in this embodiment, two spring clips 140 are provided.

[0085] Preferred, such as Figure 1 and Figure 3 As shown, the housing 120 can have two through holes 121 at the position corresponding to the guide wire plate 113 for the passage of the external power cord 200. For example, as... Figure 1 As shown, the periphery of the housing 120 has two wire holes 121, and “N” and “L” markings are respectively provided near the two wire holes 121 to allow the neutral wire and live wire of the external power cord 200 to be inserted.

[0086] The following is a brief description of some of the beneficial effects of the above-described embodiments of this application.

[0087] The integrated quick-connection downlight provided by this application allows the downlight to be connected or disconnected from an external power cord simply by pressing a connection button without the need for external tools. This integrated quick-connection downlight is convenient to install and maintain, simple to operate, and has a wide range of applications. It improves installation and maintenance efficiency while also avoiding safety hazards such as loose bolts.
