Description

Technical Field

[0001] The utility model belongs to the technical field of lighting fixtures, and in particular relates to a high-voltage cabinet lamp. Background Art

[0002] Cabinet lights refer to special lamps for cabinets, which are mainly used for local lighting and decoration of kitchen cabinets, wardrobes, display cabinets, etc. High-voltage cabinet lights usually refer to cabinet lights with an input voltage of generally 220V AC. The built-in driver power supply converts the input AC power into a DC voltage and current suitable for the operation of LED chips, so that they can be directly connected to the AC power supply for practical use.

[0003] Existing cabinet lights typically mount the PCB light board directly onto the aluminum profile lamp tube slot and then secure the PC lampshade to the lamp tube, or use a two-color extruded one-piece lamp tube to mount the PCB light board and diffuse the light. This results in the cabinet light's internal driving power supply, PCB light board and other live components being too close to the cabinet light housing, resulting in insufficient creepage distance and easily causing creepage. This can easily cause a sensation of electric shock when touching the lamp tube, and may even lead to local overheating and damage to the insulation material, causing short circuit failures and posing a safety hazard. Utility Model Content

[0008] A connecting plug is installed at both ends of the aluminum profile shell. Both connecting plugs can be connected to an external power supply. The length of the aluminum profile shell is shorter than the insulating lamp tube and the PCB light board. The side walls of the two connecting plugs respectively cover the parts of the insulating lamp tube at both ends that extend beyond the aluminum profile shell and abut against the two end surfaces of the aluminum profile shell.

[0009] In an optional solution, the lower ends of the front and rear side walls of the aluminum profile shell are bent inward to form a support portion, and the top of the aluminum profile shell is recessed downward to form a positioning portion.

[0012] In one optional solution, the connecting plug includes a cover portion, a connecting portion, and an insulating shell formed in an integral structure. The connecting portions of the two connecting plugs are each provided with a male plug that passes through the cover portion. The male plugs on the two connecting plugs are electrically connected to the driving power supply, and the driving power supply is electrically connected to the PCB light board.

[0013] The connecting portion is arranged inside the insulating lamp tube, and locking screws are provided at the corresponding connecting portions at both ends of the aluminum profile housing. The locking screws penetrate the aluminum profile housing and connect the insulating lamp tube to the connecting portion. The insulating shell is constructed on the inner end of the cover along the extension direction of the aluminum profile housing, and the cross-section of the insulating shell matches the aluminum profile housing.

[0014] When the locking screw is connected to the connecting part, the insulating shells of the two connecting plugs respectively cover the parts of the insulating lamp tube that extend beyond the aluminum profile shell at both ends, and the inner end faces of the insulating shells of the two connecting plugs respectively abut against the head and tail end faces of the aluminum profile shell.

[0015] In an optional solution, a first positioning block and a second positioning block are constructed on the inner side of the insulating shell and extend beyond the inner end surface of the insulating shell. A first embedding groove is formed in the gap between the front and rear side walls of the aluminum profile shell and the front and rear side walls of the insulating lamp tube, respectively.

When the locking screws are connected to the connecting parts, the extensions are arranged in the avoidance grooves, and the spacing between the end faces of the extensions at the both ends of the PC lampshade is consistent with the spacing between the outer end faces of the cover parts of the two connecting plugs.

[0019] In an optional solution, the PC lampshade is located below the front and rear side walls of the aluminum profile housing and is downwardly extended to form an extension portion, which coincides with the projection of the front and rear side walls of the aluminum profile housing in the horizontal plane.

[0020] In an optional scheme, it also includes at least two fixing frames, which are frame structures with openings at both ends and the bottom. The top of the fixing frame is constructed with through holes for facilitating the insertion of threaded fasteners. The front and rear side walls of the fixing frame are bent inward to form a clamping portion.

[0046] Existing cabinet lights have a problem in which the physical distance between the internal driving power supply, light board and other live components and the cabinet light housing is too close, resulting in insufficient creepage distance and easily causing creepage.

[0047] In response to the above problems, the present application makes improvements and innovations and proposes the following embodiments.

[0048] In one embodiment, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 , provides a high-voltage cabinet lamp, including an aluminum profile shell 1, a PC lampshade 2, an insulating lamp tube 3, a PCB lamp board 4, a connecting plug 5, and a driving power supply 6; wherein, the aluminum profile shell 1 is a hollow tubular structure with openings at both ends and the bottom, the PC lampshade 2 is hung on the lower end of the aluminum profile shell 1, the insulating lamp tube 3 is inserted into the aluminum profile shell 1, the PCB lamp board 4 is inserted into the insulating lamp tube 3, and the driving power supply 6 is installed on the PCB lamp board 4; the upper and lower sides of the insulating lamp tube 3 are respectively in contact with the aluminum profile shell 1 and the PC lampshade 2, and the front and rear outer walls of the insulating lamp tube 3 do not contact the front and rear inner walls of the aluminum profile shell 1.

[0049] Specifically, the lower ends of the front and rear side walls of the aluminum profile shell 1 are bent inward to form a supporting portion 11, and the top of the aluminum profile shell 1 is recessed downward to form a positioning portion 12. The supporting portion 11 and the positioning portion 12 are arranged through the aluminum profile shell 1 along the extension direction of the aluminum profile shell 1; the upper ends of the front and rear side walls of the PC lamp cover 2 are bent inward to form a hanging portion 21 that matches the supporting portion 11, and the hanging portion 21 is arranged through the PC lamp cover 2 along the extension direction of the PC lamp cover 2. The top of the insulating lamp tube 3 is recessed downward to form a positioning groove 31 that matches the positioning portion 12. The lower end of the insulating lamp tube 3 is bent inward to form a mounting portion 32 that matches the hanging portion 21. The positioning groove 31 and the mounting portion 32 are arranged through the insulating lamp tube 3 along the extension direction of the insulating lamp tube 3.

[0050] In this way, by arranging the insulating lamp tube 3 in the aluminum profile housing 1, the PCB lamp board 4, the driving power supply 6 and other live components are installed in the insulating lamp tube 3, the upper end of the insulating lamp tube 3 is in contact with the aluminum profile housing 1 through the cooperation of the positioning groove 31 and the positioning portion 12, and the lower end of the insulating lamp tube 3 is in contact with the PC lamp cover 2 through the cooperation of the mounting portion 32 and the hanging portion 21, so as to ensure that the insulating lamp tube 3 can be stably installed in the aluminum profile housing 1, while the front and rear outer side walls of the insulating lamp tube 3 do not contact the front and rear inner side walls of the aluminum profile housing 1, that is, the front and rear outer sides of the insulating lamp tube 3 The wall is spaced apart from the front and rear inner walls of the aluminum profile housing 1, thereby increasing the creepage distance between the aluminum profile housing 1 and the live parts of the PCB lamp board 4 inserted in the insulating lamp tube 3, and increasing the creepage distance between the aluminum profile housing 1 and the driving power supply 6 and other live components installed on the PCB lamp board 4, which can effectively avoid the creepage phenomenon caused by insufficient creepage distance between the aluminum profile housing and the internal live components. There will be no electric shock when touching the aluminum profile housing 1, eliminating the safety hazard of short circuit failure caused by creepage phenomenon, which is conducive to extending the service life of the cabinet lamp.

[0051] In this embodiment, please refer to Figures 1-6 、 Figure 7 、 Figure 8 A connecting plug 5 is installed at both ends of the aluminum profile shell 1. Both connecting plugs 5 can be connected to an external power supply. The length of the aluminum profile shell 1 is shorter than the insulating lamp tube 3 and the PCB lamp board 4. The side walls of the two connecting plugs 5 respectively cover the parts of the two ends of the insulating lamp tube 3 that extend beyond the aluminum profile shell 1 and abut against the two end surfaces of the aluminum profile shell 1.

[0052] Specifically, the connecting plug 5 includes a cover portion 51, a connecting portion 52, and an insulating shell 53 of an integrally formed structure. A male plug 54 that passes through the cover portion 51 is provided on the connecting portion 52 of the two connecting plugs 5. The male plugs 54 on the two connecting plugs 5 are electrically connected to the driving power supply 6, and the driving power supply 6 is electrically connected to the PCB light board 4, so that the PCB light board 4 can be powered by an external power supply through the male plug 54 of the connecting plug 5.

[0053] Among them, the connecting part 52 is arranged inside the insulating lamp tube 3, and locking screws 55 are provided at both ends of the aluminum profile shell 1 corresponding to the connecting part 52. The locking screws 55 pass through the aluminum profile shell 1 and are connected to the insulating lamp tube 3 and the connecting part 52. The insulating shell 53 is constructed on the inner end of the cover 51 along the extension direction of the aluminum profile shell 1, and the cross-section of the insulating shell 53 matches the aluminum profile shell 1; the length of the aluminum profile shell 1 is shorter than the insulating lamp tube 3 and the PCB lamp board 4. When the locking screw 55 is connected to the connecting part 52, the insulating shells 53 of the two connecting plugs 5 respectively cover the parts of the insulating lamp tube 3 that extend beyond the aluminum profile shell 1 at the head and tail ends, and the inner end faces of the insulating shells 53 of the two connecting plugs 5 respectively abut against the head and tail end faces of the aluminum profile shell 1.

[0054] In this way, by making the length of the aluminum profile shell 1 shorter than the insulating lamp tube 3 and the PCB lamp board 4, and partially replacing the aluminum profile shell 1 with the insulating shell 53 of the connecting plug 5, a cover is formed for the parts of the insulating lamp tube 3 and the PCB lamp board 4 that extend beyond the aluminum profile shell 1. This ensures that the aluminum profile shell 1 can stably install the PC lamp cover 2 and the insulating lamp tube 3, while also increasing the creepage distance between the two end parts of the aluminum profile shell 1 and the inside of the connecting plug 5 and the live components connected to the connecting plug 5, which can effectively avoid creepage caused by insufficient creepage distance.

[0055] In some embodiments, see Figure 5 、 Figure 6 The inner side of the insulating shell 53 is constructed with a first positioning block 531 and a second positioning block 532 that extend beyond the inner end surface of the insulating shell 53. A first embedding groove 101 is formed in the gap between the front and rear side walls of the aluminum profile shell 1 and the front and rear side walls of the insulating lamp tube 3. The first positioning block 531 is embedded in the first embedding groove 101. A second embedding groove 102 is formed between the supporting portion 11 of the aluminum profile shell 1 and the hanging portion 21 of the PC lamp cover 2. The second positioning block 532 is embedded in the second embedding groove 102.

[0056] In this way, on the one hand, the first positioning block 531 and the second positioning block 532 can be used to improve the installation accuracy and stability of the connecting plug 5 on the aluminum profile shell 1. On the other hand, the first positioning block 531 and the second positioning block 532 can form a support between the head and tail ends of the aluminum profile shell 1 and the insulating lamp tube 3, thereby effectively preventing the aluminum profile shell 1 and the insulating lamp tube 3 from being deformed and causing the creepage distance to be shortened.

[0057] In some embodiments, see Figure 5The top of the insulating shell 53 corresponds to the support part 11 of the aluminum profile shell 1 and is configured with a sealing part 533 that protrudes downward. The shape of the sealing part 533 matches the support part 11 of the aluminum profile shell 1 and the groove formed by the downward depression of the support part 11. When the locking screw 55 is connected to the connecting part 52, the sealing parts 533 of the two connecting plugs 5 respectively abut against the corresponding positions of the head and tail end surfaces of the aluminum profile shell 1, so that the sealing part 533 can be used to seal the groove at the top of the aluminum profile shell 1, which can effectively prevent dust from entering the interior of the aluminum profile shell 1 from the gap between the groove and the connecting plug 5.

[0058] In some embodiments, see Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 8 , further comprising an end plug 7, which comprises an integrally formed cover plate 71 and a blocking block 72. The cover plate 71 overlaps with the projections of the aluminum profile housing 1 and the connecting plug 5 on the end plane of the aluminum profile housing 1, and the blocking block 72 mates with the male plug 54. Thus, by mating the blocking block 72 with the male plug 54, the end plug 7 can be installed on the connecting plug 5, thereby sealing the connecting plug 5 with the cover plate 71 and blocking block 72. Specifically, when the cabinet light is used alone, the end plug 7 is installed at the rear end of the cabinet light. When multiple cabinet lights are connected in series, the end plug 7 is installed at the rear end of the cabinet light.

[0059] In some embodiments, see Figure 1 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 The PC lampshade 2 has extensions 22 at both ends that extend beyond the insulating lamp tube 3. The covers 51 of the two connecting plugs 5 have corresponding relief grooves 511 formed on the extensions 22. When the locking screws 55 are connected to the connecting parts 52, the extensions 22 are positioned within the relief grooves 511. Furthermore, the spacing between the end faces of the extensions 22 at both ends of the PC lampshade 2 matches the spacing between the outer end faces of the covers 51 of the two connecting plugs 5. This ensures that the PC lampshade 2 covers the entire underside of the cabinet light, ensuring that the luminous surface covers the entire underside of the cabinet light. This eliminates dark areas on the luminous surface of the cabinet light, resulting in a good lighting effect and a beautiful luminous effect.

[0060] In this embodiment, Figure 7 、 Figure 8As shown, the connecting parts 52 of the two connecting plugs 5 are both provided with male plugs 54 that pass through the cover part 51. In this way, the cabinet light can be connected to an external power supply by adopting a power cord with a female socket that matches the male plug 54. By adopting a double-female adapter 9 that matches the male plug 54, multiple cabinet lights can be spliced ​​end to end in sequence. By adopting a male-female connecting wire 10 that matches the male plug 54 and a double-female adapter 9, multiple cabinet lights can be connected end to end in sequence.

[0061] Among them, Figure 8 As shown, by making the spacing between the end faces of the extension parts 22 at the head and tail ends of the PC lampshade 2 consistent with the spacing between the outer end faces of the cover parts 51 of the two connecting plugs 5, the luminous surface of the cabinet lamp covers the entire lower side surface of the cabinet lamp. When two or more cabinet lamps of the present invention are spliced ​​end to end in sequence through the double female adapter 9, the outer end face of the connecting plug 5 at the tail end of the previous cabinet lamp abuts against the outer end face of the connecting plug 5 at the head end of the next cabinet lamp. At this time, the end face of the tail end of the PC lampshade 2 of the previous cabinet lamp is in close contact with the end face of the head end of the PC lampshade 2 of the next cabinet lamp. In this way, seamless splicing of the PC lampshades 2 of the two adjacent cabinet lamps spliced ​​end to end can be achieved, so that the luminous surfaces of the cabinet lamps spliced ​​end to end can be continuously connected, which can effectively avoid the dark area formed due to the existence of the end plugs when traditional cabinet lamps are spliced ​​end to end. The cabinet lamp has good continuity and integrity of light emission and good lighting effect.

[0062] In some embodiments, see Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 The PC lampshade 2 is located below the front and rear sidewalls of the aluminum profile housing 1 and extends downward to form an extension 23. The extension 23 coincides with the horizontal projection of the front and rear sidewalls of the aluminum profile housing 1. This allows the cabinet light's light-emitting surface to extend below the front and rear sidewalls of the aluminum profile housing 1 through the extension 23. This allows the extension 23 to provide lateral fill light to the front and rear sides of the cabinet light, thereby improving the cabinet light's lighting effect.

[0063] In some embodiments, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 9, also includes at least two fixing brackets 8, the fixing bracket 8 is a frame structure with openings at both ends and the bottom, and the top of the fixing bracket 8 is constructed with a through hole 81 for passing a threaded fastener, so that the threaded fastener can pass through the through hole 81 to fix the fixing bracket 8 on an installation foundation such as a wall or a cabinet; the front and rear side walls of the fixing bracket 8 are bent inward to form a clamping portion 82, and the insulating shells 53 of the two connecting plugs 5 and the aluminum profile shell 1 are constructed with a card slot 13 that matches the clamping portion 82. The card slot 13 passes through the aluminum profile shell 1 and the insulating shell 53 along the extension direction of the aluminum profile shell 1, so that the cabinet lamp can be installed on the fixing bracket 8 through the cooperation of the card slot 13 and the clamping portion 82.

[0064] In this embodiment, the top of the fixing frame 8 is constructed with an elastic clip 83 arranged obliquely downward. When the aluminum profile shell 1 is clamped on the fixing frame 8, the top of the aluminum profile shell 1 is pressed against the elastic clip 83. In this way, the downward pressure of the elastic clip 83 can make the card slot 13 on the aluminum profile shell 1 fully cooperate with the clamping part 82, thereby effectively preventing the cabinet light from shaking on the fixing frame 8 and effectively improving the installation stability of the cabinet light.

[0065] Finally, it should be noted that although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present invention. Ordinary technicians in this field can make changes, modifications, replacements and variations to the above embodiments within the scope of the present invention, which should all be included in the scope of protection of this application.
