[0002] LED lights are a widely used lighting device with advantages such as environmental friendliness, energy saving, and high efficiency. In some scenarios, such as long advertising light boxes, shopping mall display cases, and factories, long tube lights are generally chosen to achieve a wider and more uniform lighting effect.
[0003] Existing long fluorescent tubes are difficult to transport and store due to their length. Therefore, splicable lamps have been introduced to the market, which are generally connected by male and female plugs. Due to the characteristics of their structure, the conductive part of the male plug is relatively exposed and easily touched. When a lamp tube with a male plug is powered on alone, there is a certain safety hazard. Utility Model Content

[0034] See Figures 1-4 One embodiment of this application provides a splicable lamp fixture, which has a split state and a spliced state, including a first lamp body 100 and a second lamp body 200 that can be connected to each other.
[0035] The first lamp body 100 includes a first lamp tube 110, a first lamp head 120 disposed at one end of the first lamp tube 110, and a first connecting element 130 disposed at the other end of the first lamp tube 110. The second lamp body 200 includes a second lamp tube 210, a second lamp head 220 disposed at one end of the second lamp tube 210, and a second connecting element 230 disposed at the other end of the second lamp tube 210. The first lamp tube 110 and the second lamp tube 210 respectively house a first light-emitting component 111 and a second light-emitting component 211. The first light-emitting component 111 includes a first substrate 112 and a first light-emitting element 113 disposed on the first substrate 112. The second light-emitting component 211 includes a second substrate 212 and a second light-emitting element 213 disposed on the second substrate 212. Considering the uniformity of illumination during light emission, there are multiple first light-emitting elements 113 and second light-emitting elements 213, which are uniformly arranged along the axial direction of their respective substrates.
[0036] Furthermore, the first connecting element 130 is provided with a female plug 131 electrically connected to the first light-emitting component 111, and the second connecting element 230 is provided with a male plug 231 electrically connected to the second light-emitting component 211 (electrical connection is achieved through a wire). The female plug 131 and the male plug 231 are respectively provided with a first conductive part and a second conductive part 232. In the spliced state, the first lamp tube 110 and the second lamp tube 210 are on the same straight line, the first connecting element 130 and the second connecting element 230 are close to each other, and the female plug 131 and the male plug 231 cooperate with each other (the first conductive part and the second conductive part 232 are connected) to achieve electrical connection.
[0037] See Figures 3-4 The second conductive part 232 of the male plug 231 is relatively exposed and easily touched. If the second lamp body 200 is powered on alone, there is a risk of accidental contact and leakage of electricity to the male plug 231. In order to avoid this problem, the splicable lamps of this application also include a removable protective element 250 that is set on the second lamp body 200 to shield the second conductive part 232.
[0038] In the separate state, the protective element 250 is disposed on the second lamp body 200 to shield the second conductive part 232, avoiding leakage when the male plug 231 is accidentally touched, thus making it safer; when the lamp needs to be spliced into a whole lamp, the protective element 250 is removed, and the male plug 231 is connected to the female plug 131 to achieve electrical connection, so as to realize the electrical connection between the first light-emitting component 111 and the second light-emitting component 211.
[0039] In one embodiment, the second connecting element 230 has a cylindrical structure, and the male plug 231 and the protective element 250 are disposed inside the second connecting element 230. In order to shield the second conductive part 232, the male plug 231 is disposed closer to the second lamp tube 210 relative to the protective element 250.
[0040] See Figures 4-6 The protective element 250 is positioned and engaged with the second connecting element 230. Specifically, the protective element 250 includes a main body 251 that is adapted to the inner peripheral surface of the second connecting element 230 and an operating part 256 that protrudes outward from the front of the main body 251. The main body 251 is interference-fitted with the inner peripheral surface of the second connecting element 230, and the operating part 256 is designed to facilitate the operator to pinch and push the protective element 250 into or pull it out of the second connecting element 230.
[0041] Of course, in order to ensure a smooth fit between the protective element 250 and the inner circumferential surface, the main body 251 is provided with a positioning groove 252, and the second connecting element 230 is provided with a positioning protrusion 233. Furthermore, the positioning protrusion 233 extends axially, that is, when the protective element 250 needs to be installed, the positioning groove 252 can be aligned with the positioning protrusion 233 and gradually extended into the second connecting element 230 along the direction of the positioning protrusion 233.
[0042] In one embodiment, see Figure 6 and 9~ Figure 10 The second connecting element 230 has a second positioning plate 234 for fixing the male plug 231 inside, and a positioning protrusion 233 extends axially from the second positioning plate 234. The middle area of the second positioning plate 234 has a second positioning hole 235 that is adapted to the male plug 231 and a plurality of second anti-disengagement hooks 236 that cooperate with the male plug 231.
[0043] To avoid affecting the male plug 231 when the protective element 250 extends into the second connecting element 230 at its extreme position (i.e., when the back of the main body 251 abuts against the second positioning plate 234), a clearance groove 253 for accommodating the male plug 231 is also provided on the back of the main body 251.
[0044] See Figures 7-8 The first connecting element 130 has a cylindrical structure. The female plug 131 is arranged inside the first connecting element 130. The first connecting element 130 is provided with a first positioning plate 133 for fixing the female plug 131. The middle area of the first positioning plate 133 has a first positioning hole 134 adapted to the female plug 131 and a plurality of first anti-disengagement hooks 135 arranged around the first positioning hole 134.
[0045] To ensure the positioning and installation of the second lamp tube 210 and the second connecting element 230, the second lamp tube 210 abuts against the second positioning plate 234. To ensure the positioning and installation of the first lamp tube 110 and the first connecting element 130, the first lamp tube 110 abuts against the first positioning plate 133.
[0046] In addition, during assembly, one end of the second connecting element 230 abuts against the first positioning plate 133, making the overall structure compact and stable.
[0047] In the spliced state, the first connecting element 130 and the second connecting element 230 are nested together, and a snap-fit structure is provided between them to restrict their separation.
[0048] See Figures 8-10To facilitate connection, the inner wall of the first connecting element 130 is provided with an axially extending guide groove 140, and correspondingly, the outer wall of the second connecting element 230 is provided with a guide block 240 corresponding to the guide groove 140. There are three guide grooves 140 and three corresponding guide blocks 240. This structure serves two purposes: firstly, it provides positioning and installation for accurate assembly; secondly, it restricts the circumferential rotation of the first connecting element 130 and the second connecting element 230.
[0049] See Figures 2-3 The snap-fit structure includes a first spring piece 237 with a snap protrusion 238 on the second connecting element 230 and a second spring piece 136 on the first connecting element 130. When splicing is required, the snap protrusion 238 is pressed and rubbed against the inner wall of the first connecting element 130, while the first spring piece 237 moves inward until the snap protrusion 238 is located at the second spring piece 136. At this time, the spring piece moves outward to reset until it abuts against the second spring piece 136, and the two are in an axially limited state. When separation is required, the second spring piece 136 is pressed down. At this time, the snap protrusion 238 is squeezed, and the corresponding first spring piece 237 moves inward until the limited state is released. At this time, applying forces in opposite directions on the two lamp tubes can separate them.
[0050] During assembly, the second connecting element 230 is fully inserted into the interior of the first connecting element 130, which is beneficial to the safety of the connection between the first lamp body 100 and the second lamp body 200 and improves the overall aesthetics of the lamp.
[0051] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.
[0052] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
