Description
Technical Field
[0001] The utility model relates to an office lamp, in particular to an LED spliced frame lamp. Background Art
[0002] This technical background specifically mentions the publicly authorized ZL2022232797296 patent, the main technical points of which are: welding conductive springs on the lamp board, using metal sheets as the splicing parts, and the welded conductive springs at both ends of the lamp board and the metal splicing sheets are in elastic contact to transmit electricity. The technology looks simple and reliable, but there are many problems: First, the temperature of the LED lamp board is very high during operation. When used in summer, the temperature of the lamp board can reach over 80°C. More importantly, the contact resistance between the conductive springs and the metal splicing sheets is very large. The lamp has high power. For safety reasons, the input voltage on the lamp board is small, the current flowing through the lamp board is large, and the heat generated by the contact resistance is large. The temperature of the conductive springs on the lamp board is very high. The conductive springs work at high temperatures for a long time, and their elastic pressure will decrease quickly. There is no backrest design on the back of the conductive springs on the lamp board, and due to several splicing There are many contact points and welding points. The soldering surface of the conductive springs at the contact points is not well connected at high temperatures, which will cause many problems and many dead lights. Second, the large number of conductive springs will greatly increase the labor cost. Third, some people say that the problem of the technical structure can be solved by increasing the width and thickness of the conductive springs, but the joint here is a right angle, and the space is very limited. In addition, increasing the width and thickness of the conductive springs will occupy a large amount of space on the lamp board, which will block the light output angle of the lamp beads and cause dark areas. Fourth, the conductive springs on the lamp board of this technical structure pass through the lamp board substrate, causing damage to the lamp board, which also causes poor heat dissipation of the lamp beads on the lamp board near the perforation. Fifth, the conductive splicing metal sheet of this technical solution will have exposed gaps at the splicing of the LED lamp tubes, and it will not be able to be spliced so tightly. Electricians are likely to touch the conductive splicing metal sheet during operation, which will cause the risk of electric shock. Therefore, this technical solution is not good and unreliable, and both enterprises and users will suffer serious losses. Utility Model Content

[0033] As those skilled in the art can fully understand, the features of the different embodiments of the present disclosure can be coupled or combined with each other in part or in whole, and can cooperate with each other in various ways and be driven technically. The embodiments of the present disclosure can be performed independently of each other, or can be performed together in a mutually dependent relationship.
[0034] Reference Figure 1 , Figure 2 and Figure 8 The utility model discloses an LED splicing frame lamp, comprising a lamp body 1, a plurality of lamp bodies 2 and a plurality of splicing pieces 3. The lamp body 1 and the plurality of lamp bodies 2 are connected by the splicing pieces 3 to form a lamp.
[0035] The lamp body in the present application is a square closed frame, the lamp body 1 includes a lamp tube 103, a lamp board 102 and an input line 101, the input line 101 is connected to an external power supply to supply power to the lamp body, the lamp body 2 includes a lamp tube 202 and a lamp board 201, both ends of the lamp board 102 and the lamp board 201 are provided with conductive contacts 1021, the lamp board 102 and the lamp board 201 can be conventional copper-clad aluminum substrates, on which a number of LED chips are welded, the lamp tube 103 and the lamp tube 202 are both provided with a slot 2 1032, the lamp board 102 and the light board 201 are arranged in the slot 2 1032. The splicing piece 3 includes a splicing body 302 and a conductive sheet 301 fixed in the splicing body 302. When the lamp body 1 and the lamp body 2 are spliced with the corresponding splicing piece 3, the conductive sheet 301 can contact with the corresponding conductive contact 1021 and be electrically connected. The lamp board 1 102, a plurality of conductive sheets 301, a plurality of lamp boards 201 and the input line 101 constitute a reliable electrical path, realizing a welding-free conductive sheet process, thereby realizing the electrical connection series of the lamp body 1 and all the lamp bodies 2. The conductive sheet 301 is preferably a copper sheet, and the conductive contact 1021 is a copper foil.
[0036] like Figures 3 to 7As shown, the splicing body 302 includes a neutral plate 3022 , a first splicing portion 3021 and a second splicing portion 3023 that are oppositely disposed. The neutral plate 3022 is disposed between the first splicing portion 3021 and the second splicing portion 3023 , and the conductive sheet 301 is disposed on the second splicing portion 3023 . The neutral plate 3022, the relatively arranged first splicing part 3021 and the second splicing part 3023 are integrally injection-molded as a splicing piece 3 using fully transparent plastic. A card slot 1031 is provided at the bottom of the lamp tube 1 103 and the lamp tube 2 202. The card slot 1031 is located below the card slot 1032 and closer to the bottom surface of the lamp tube 1 103 or the lamp tube 2 202. The two side edges of the first splicing part 3021 can be inserted into the corresponding card slot 1031, and the lamp tube 1 103 and the lamp tube 2 202 can be plugged with the corresponding second splicing part 3023. Therefore, the above structure is easy to plug in, and the conductive sheet 301 will not be exposed to the outside. The neutral plate 3022 can play a role in strengthening the overall strength of the splicing body 302. After being spliced into a lamp through the splicing piece 3, the overall rigidity is good.
[0037] A gap 3024 is provided between the first splicing part 3021 and the second splicing part 3023, and the lamp board 1 102 and the lamp board 2 201 can be inserted into the corresponding gap 3024, so that when the splicing piece 3 connects the lamp body 1 and the lamp body 2 2, the lamp board can also be reversely embedded in the splicing piece 3 through the gap 3024 to contact with the conductive sheet 301. Specifically, the second splicing part 3023 is an arc cylinder, and the shape corresponds to the internal shape of the lamp body. The gap 3024 is connected with the side opening of the arc cylinder, so that the conductive sheet 301 can contact with the conductive contact 1021 on the lamp board through the side opening. The specific structure is: the second splicing part 3023 is provided with The support plate 3025 is "L"-shaped and one side of the support plate 3025 is connected to the edge of the side opening. The two ends of the conductive sheet 301 are bent into hooks and hook the corresponding ends of the support plate 3025. In order to facilitate installation, an "L"-shaped hole is provided on the first splicing portion 3021. The support plate 3025 is located at the edge of the side opening and is parallel to the first splicing portion 3021. Therefore, after the lamp board is embedded in the gap 3024, the conductive sheet 301 can contact the conductive contact 1021. The conductive sheet 301 works at high temperature for a long time, and its elastic pressure will decrease quickly. However, the conductive sheet 301 of the present application can maintain a certain elastic pressure through the support of the support plate 3025, thereby ensuring the electrical connection effect at high temperature.
[0038] As a further preferred structure, the conductive sheet 301 is bent to form a raised elastic contact portion 3011, and the elastic contact portion 3011 is in a "V" shape. The conductive contact 1021 is in contact with the elastic contact portion 3011. The bending not only makes the elastic contact portion 3011 more elastic, but also improves the contact pressure between the elastic contact portion 3011 and the conductive contact 1021. In addition, the contact between the elastic contact portion 3011 and the conductive contact 1021 is line contact, which has low friction and is easy to assemble.
[0039] As a further preferred structure, the second splicing portion 3023 has a taper, so that after the second splicing portion 3023 is inserted into the lamp tube, it can fit more and more tightly with the inner wall. After the second splicing portion 3023 is squeezed, the gap width of the gap 3024 becomes smaller, and the contact pressure between the conductive sheet 301 fixed on the second splicing portion 3023 and the conductive contact 1021 on the lamp board 201 becomes greater and greater. When the plug-in splicing is completed, the conductive sheet 301 and the conductive contact 1021 on the LED lamp board 201 will continue to be in close and reliable contact to transmit electricity, and the place where the second splicing portion 3023 and the lamp tube are inserted is also firm and not easy to loosen.
[0040] The LED splicing border light provided by the embodiment of the utility model is introduced in detail above. The principle and implementation mode of the utility model are explained in detail by using specific examples in this article. The description of the above embodiments is only used to help understand the method and core idea of the utility model. At the same time, for the general technical personnel in this field, according to the idea of the utility model, there will be changes in the specific implementation mode and the scope of application. In summary, the content of this specification should not be understood as a limitation on the utility model.
