Description

Technical Field

[0001] The present application relates to the field of lighting technology, and in particular to a high-voltage cabinet lamp. Background Art

[0002] High-voltage cabinet lights usually refer to cabinet lights that work with 220V voltage. Compared with low-voltage cabinet lights, they are well adapted to the existing circuit system and do not require additional transformers or power adapters. This not only makes their own manufacturing costs usually lower, but also eliminates the step of placing transformers during installation. The installation process is relatively simple and the accessories are highly versatile. Not only that, in terms of brightness and light efficiency, high-voltage power supplies can provide higher power for lamps, so that the lamps can achieve higher brightness. For some large cabinet spaces that require strong lighting (such as wall cabinets or floor cabinets in large open kitchens), high-voltage cabinet lights can better meet the lighting needs. Therefore, buyers usually prefer high-voltage cabinet lights when facing these needs.

[0003] There are also some problems in the application of high-voltage cabinet lights. The working voltage of high-voltage cabinet lights is relatively high, which puts higher requirements on their electrical safety. A more common way is to add an insulating protective cover inside the lamp housing, and install the PCB board inside the protective cover. In this way, the live components and circuits of the PCB board can be isolated from the outside world, thereby preventing the human body from accidentally contacting the live parts and ensuring the safety of the user.

[0004] In actual use, in order to facilitate the control of the lamps in the cabinet space, such as switching, brightness adjustment, color temperature adjustment, etc., a dial button is generally provided on the surface of the lamp body shell for user operation. For example, in the LED lamp disclosed in the Chinese patent with announcement number CN218582925U, two dial blocks and two inverted buckles are provided at the inner end of the dial switch, and the two dial blocks are connected to the dial head of the PCB coder through the opening on the lamp shell, and the two inverted buckles are buckled on the inner walls on both sides of the opening on the shell, thereby completing the installation of the dial button, and the dial head of the coder is dialed by toggling the dial button left and right to achieve lamp control.

[0005] The insulating protective cover inside the high-voltage cabinet light is generally made of hard plastic, which can provide reliable insulation protection and support for the lamp. At present, in the market, facing the demand for miniaturization and compactness of lamps, the overall size of lamps is shrinking, but in order to adapt to and stabilize the high-voltage power supply, the size of the PCB board and the wires usually cannot be reduced, which leads to a small space inside the lamp. This will easily lead to the pre-tightening force of the fasteners after the lamp is assembled and locked. The outer shell and the larger wires inside will squeeze the insulating protective cover, and then deform, directly causing the opening of the dial button on the insulating protective cover to be unable to align with the opening on the outer shell. In this case, the position of the dial button during assembly will not accurately correspond to the dial head of the encoder, and the dial button after installation will be blocked or not fixed firmly due to position error.

[0042] The specific implementation methods of the present application are further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application, but are not intended to limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application rather than all embodiments, and all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of this application.

[0043] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0044] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0045] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or communication with each other; it can be a direct connection, or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0046] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0048] In this application, the concept of "roughly" describes the main features of an overall structure or shape. When describing the shape of an object, it means that the object mainly presents a certain shape, but may differ in non-functional details. These detailed differences do not affect the overall characteristics, so they can be classified as "roughly" a certain shape. For example, when describing a round object, the expression "roughly round" means that the overall shape of the object is round, but there are differences in certain non-functional details. Similarly, when describing a cube, the expression "roughly cubic" means that the overall shape of the object is a cube, but there are differences in certain non-functional details.

[0049] In order to solve the problems existing in the existing high-voltage cabinet lamps mentioned in the background technology, the present application makes improvements and innovations and proposes the following embodiments.

[0050] In some embodiments, see Figure 1 , Figure 2 , Figure 3 and Figure 5 , provides a high-voltage cabinet light, comprising:

[0051] A housing 1, wherein a first through hole 101 is formed on the housing 1;

[0052] An insulating protective cover 2, wherein a second through hole 201 corresponding to the first through hole 101 is formed on the insulating protective cover 2;

[0053] A PCB board 3, on which a code dial 301 is provided;

[0054] A dial button 5, wherein a protruding first connecting portion 501 is configured on the inner side of the dial button 5; and

[0055] The connecting member 4 comprises a substantially sheet-shaped base 401, substantially symmetrical supporting wings 403 are respectively configured on both sides of the base 401, and a second connecting portion 402 and a third through hole 404 are respectively configured in the middle of the base 401;

[0056] Among them, the insulating protection cover 2 is nested in the outer shell 1, the PCB board 3 is fixedly arranged on one side of the insulating protection cover 2, the connecting member 4 is embedded in the insulating protection cover 2 on the other side relative to the PCB board 3, and the supporting wings 403 on both sides of the connecting member 4 are respectively abutted against the inner wall of the insulating protection cover 2, the dial button 5 can be relatively slidably arranged on the outer shell 1, the dial button 5 and the second connecting part 402 are relatively fixedly arranged, and the first connecting part 501 passes through the first through hole 101, the second through hole 201 and the third through hole 404 in sequence and then is connected to the dial head of the encoder 301.

[0057] In this example, the insulating protective cover 2 is nested in the housing 1, and the PCB board 3 is fixed in the insulating protective cover 2, thereby isolating the PCB board 3 from the housing 1 to ensure the electrical safety of the lamp body. On this basis, the connector 4 is embedded in the insulating protective cover 2 on the other side of the PCB board 3, thereby forming a double-sided support for the inner side of the insulating protective cover 2 by the PCB board 3 and the connector 4. Specifically, it can be as follows Figure 3 As shown, the PCB board 3 can be installed on the lower side of the insulating protective cover 2 to form a support, and the connector 4 is embedded in the upper side of the insulating protective cover 2 to form a support. In this way, after the lamp is assembled and tightened, the extrusion force applied to the insulating protective cover 2 by the pre-tightening force of the fastener can be shared by the PCB board 3 and the connector 4 respectively, which on the one hand reduces the pressure on the PCB board 3, and on the other hand, under the supporting and positioning effect of the PCB board 3 and the connector 4, the problem of misalignment of the first through hole 101 and the second through hole 101 can be effectively avoided, ensuring that the positions of the two are accurately aligned, and ensuring the accuracy and firmness of the mating structure of the dial button 5.

[0058] In addition, the connecting member 4 can also be the installation position of the dial button 5. The dial button 5 is fixedly connected to the connecting member 4. When the dial button 5 is turned, the connecting member 4 can slide with the dial button 5 relative to the insulating protective cover 2. In this way, a certain degree of positioning and guiding effect is also provided for the sliding operation of the dial button 5, further improving the structural stability and operability.

[0059] In some embodiments, see Figure 5 , Figure 6 , Figure 7 and Figure 8 The support wing 403 includes an integrally formed support end 4031, an extension section 4032 and a connection end 4033. The connection end 4033 is fixed to a substantially middle position of the side surface of the base 401. The support end 4031 is constructed on the other end of the extension section 4032 relative to the connection end 4033. The support end 4031 protrudes relative to the extension section 4032 along the width direction of the base 401, and the support end 4031 abuts against the inner wall of the insulating protective cover 2.

[0060] The support wing 403 contacts and abuts against the inner wall of the insulating protective cover 2 through the support end 4031, and the contact position between the support end 4031 and the insulating protective cover 2 can be regarded as a point or a line. In this way, the insulating protective cover 2 can be supported during assembly to prevent excessive deformation, and the contact surface between the connecting member 4 and the insulating protective cover 2 can be minimized, that is, the friction force when the connecting member 4 slides relative to the insulating protective cover 2 is reduced, thereby reducing the force required to apply when operating the dial button 5, and improving its operability and applicability.

[0061] In some embodiments, see Figures 4 to 8 , there is a gap between the extension section 4032 and the side of the base 401, the extension section 4032 extends toward both sides roughly along the length direction of the base 401, and the extension section 4032 is roughly parallel to the side of the base 401, so that the support wing 403 has a deformation space along the width direction of the connecting member 4 with the connecting end 4033 as the fulcrum, and its deformation amount can be controlled by setting the gap between the extension section 4032 and the base 401, the length and angle of the extension section 4032, etc. In this way, the extrusion force generated during assembly acts on the support wing 403, and the support wing 403 will play a certain degree of buffering role with its own deformation, avoiding damage caused by rigid impact. At the same time, due to the existence of this deformation space, when the support member slides with the dial button 5, it is not easy to cause the problem of blocking failure due to local deformation of the insulating protective cover 2.

[0062] In some embodiments, see Figure 3 , Figure 5 and Figure 6 , the high-voltage cabinet light also includes: a first fastener 6;

[0063] One end of the second connection part 402 extends roughly along the normal direction of the base 401, the third through hole 404 is arranged near the second connection part 402, and the dial button 5 and the second connection part 402 are respectively provided with connection holes; wherein, after the first connection part 501 passes through the third through hole 404, the adjacent side surfaces of the first connection part 501 of the dial button 5 abut against each other, and the first fastener 6 passes through the dial button 5 and the first connection part 501 in turn and is locked. The dial button 5 and the connection member 4 are connected and locked from the outside to the inside by the fastener, which facilitates the disassembly and assembly of the dial button 5.

[0064] In some embodiments, see Figures 5 to 9 A substantially semi-cylindrical positioning protrusion 4021 is configured on one side of the second connecting portion 402 adjacent to the third through hole 404, a first limiting protrusion 4022 is configured on the other side of the second connecting portion 402 away from the positioning protrusion 4021, a positioning groove 5011 corresponding to the positioning protrusion 4021 is configured on the second connecting portion 402, and two second limiting protrusions 502 are arranged on the dial button 5;

[0065] During assembly, the positioning protrusion 4021 is first embedded in the positioning groove 5011 and abutted against each other, and the first limiting protrusion 4022 is embedded between the two second limiting protrusions 502. Thus, after the dial button 5 and the second connecting portion 402 are fastened and fixed, a double-sided positioning is formed between the two in the sliding direction of the dial button 5, ensuring that the structure of the connection is stable and reliable and not easy to loosen.

[0066] In some embodiments, see Figure 6 and Fig. 9 The first connecting portion 501 is constructed with two spaced connecting posts 5012. During assembly, the two connecting posts 5012 are aligned so that the dial head of the code dial 301 is embedded between the two connecting posts 5012. No other matching positioning structure is required, which is conducive to improving the convenience of the assembly process of the dial button 5.

[0067] In some embodiments, see Figures 1 to 3 The high-voltage cabinet lamp further includes: a lampshade 7; the upper portion of the lampshade 7 is embedded in a position between the housing 1 and the insulating protective cover 2, and the upper portion of the lampshade 7 abuts against the inner wall of the housing 1 and the outer wall of the insulating protective cover 2 respectively.

[0068] In some embodiments, see Figures 1 to 3 , high voltage cabinet lights also include:

[0069] End cover 8 and second fastener 9;

[0070] The end cover 8 is configured with an insertion end 801 protruding toward one side, and connection holes are configured on the housing 1 , the insulating protective cover 2 and the insertion end 801 , respectively.

[0071] During assembly, the connector 4 is first embedded in one side of the insulating protective cover 2, and the second connecting portion 402 extends out of the second through hole 201, and then the PCB board 3 is embedded in the other side of the insulating protective cover 2 to complete the partial assembly of the insulating protective cover 2. Secondly, the completed part is embedded in the housing 1, and the second through hole 201 is aligned with the first through hole 101. Then, the upper part of the lampshade 7 is first embedded in the position between the housing 1 and the insulating protective cover 2, and then the two side end covers 8 are closed at both ends of the housing 1, and the insertion end 801 is embedded under the insulating protective cover 2 to ensure that the wire 10 is completely placed in the insulating protective cover 2. The second fastener 9 is used to pass through the connection holes on the housing 1, the insulating protective cover 2 and the insertion end 801 in turn, and then the three are locked. Finally, the first fastener 6 passes through the dial button 5 and the first connecting portion 501 in turn and is locked, and the installation of the dial button 5 is completed, and the assembly of the entire lamp body is completed. The whole process is convenient and fast, and the reliability and convenience of the installation structure of the dial button 5 are taken into account.
