Technical Field

[0001] This utility model belongs to the field of lighting technology, and in particular relates to a book lamp that is easy to replace with a built-in light source. Background Technology

[0002] As a portable lighting device, the book lamp is widely used in reading, studying, and nighttime lighting scenarios due to its lightweight, convenient, and flexible features.

[0003] However, most reading lamps on the market currently adopt a one-piece molding design, where the light source (usually an LED strip) is fixedly connected to the lamp housing body by welding or gluing, forming a non-removable integral structure. This design means that when the light source needs to be upgraded due to natural aging, accidental damage, or technological iteration, users cannot replace it individually and must discard the entire product. Even a minor light source malfunction can render the entire lamp unusable, significantly increasing user costs and wasting resources. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a book lamp that allows for easy replacement of the built-in light source, solving the problem of resource waste caused by the inability to replace the light source in existing devices.

[0005] This utility model is implemented as follows: a book lamp that facilitates the replacement of its built-in light source, including a lamp housing, and further comprising:

[0006] An active light strip is installed on the underside of the lamp housing for illumination. Both the light strip and the inner side of the lamp housing are provided with electrode plates, and the two electrode plates are electrically connected.

[0007] The lamp housing has two holes on its lower side for inserting the lamp strip into the lamp housing, and the top of the lamp strip is provided with a plug rod. When the plug rod is inserted into the hole, the two electrode plates form a circuit path.

[0008] As a preferred embodiment of this utility model, the lamp housing is provided with a connecting component for connecting the lamp housing and the lamp strip. The connecting component includes a magnetic block movably disposed in the socket and a magnetic block fixedly disposed on the top of the lamp strip. When the plug is inserted into the socket, the two magnetic blocks magnetically attract each other.

[0009] As a preferred embodiment of this utility model, a first spring is fixedly installed inside the socket, and a disc is fixedly installed at the bottom of the first spring, with the diameter of the disc being larger than the diameter of the bottom of the socket, and the magnetic block is fixedly installed on the disc.

[0010] As a preferred embodiment of this utility model, a push plate is inclinedly arranged on the disc, and a scraper is symmetrically slidably arranged inside the lamp housing. When the push plate moves down, the end of the scraper cleans the surface of the electrode sheet inside the lamp housing. The scraper is made of insulating material.

[0011] As a preferred embodiment of this utility model, a second spring for resetting is provided on both sides of the scraper, a sliding groove is provided on the inner side of the lamp housing, the scraper is slidably disposed in the sliding groove, and the second spring is fixedly disposed on both sides of the sliding groove.

[0012] As a preferred embodiment of this invention, the bottom of the lamp housing is provided with a storage groove for placing the lamp strip.

[0024] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0025] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 5 As shown in the figure, the present invention provides a book lamp that is easy to replace with a built-in light source, including a lamp housing 1 and a light strip 2 movably disposed on the lower side of the lamp housing 1 for illumination. Both the light strip 2 and the inner side of the lamp housing 1 are provided with electrode plates 5, and the two electrode plates 5 are electrically connected. The lower side of the lamp housing 1 has two insertion holes 3 for inserting the light strip 2 into the lamp housing 1, and the top of the light strip 2 is provided with a plug. When the plug is inserted into the insertion hole 3, the two electrode plates 5 form a circuit path.

[0027] As a preferred embodiment of this invention, the lamp housing 1 is provided with a connecting component 4 for connecting the lamp housing 1 and the lamp strip 2. The connecting component 4 includes a magnetic block 42 movably disposed within the socket 3 and a magnetic block 42 fixedly disposed on the top of the lamp strip 2. When the insert is inserted into the socket 3, the two magnetic blocks 42 magnetically attract each other. Through the mutual attraction of the two magnetic blocks 42, the lamp strip 2 can be effectively fixed to the bottom of the lamp housing 1, while ensuring that the electrode plate 5 on the lamp strip 2 and the electrode plate 5 inside the lamp housing 1 are electrically connected, so that the lamp strip 2 remains energized, thereby achieving the lighting effect of the device. When replacing, simply separate the two magnetic blocks 42 to disassemble the lamp strip 2 and complete the replacement of the lamp strip 2.

[0028] In a preferred embodiment of this invention, a first spring 41 is fixedly installed inside the socket 3. A disc is fixedly installed at the bottom of the first spring 41, and the diameter of the disc is larger than the diameter of the bottom of the socket 3. A magnetic block 42 is fixedly installed on the disc. When the two magnetic blocks 42 attract each other, the installation stability of the light strip 2 can be effectively guaranteed. During disassembly, the light strip 2 is pulled down, and the first spring 41 is gradually stretched. When the disc at the bottom of the first spring 41 contacts the bottom of the socket 3, the disc is blocked because its diameter is larger than the diameter of the bottom of the socket 3. If the light strip 2 is pulled down further, the two magnetic blocks 42 can be separated, thereby completing the disassembly of the light strip 2 and facilitating its replacement.

[0029] In a preferred embodiment of this invention, a push plate 43 is inclinedly arranged on the disc, and a scraper 44 is symmetrically slidably arranged inside the lamp housing 1. When the push plate 43 moves downward, the end of the scraper 44 cleans the surface of the electrode sheet 5 inside the lamp housing 1. The scraper 44 is made of insulating material. When the lamp strip 2 is pulled down for disassembly, the disc descends, and the first spring 41 is stretched. As the disc descends, the push plate 43 gradually squeezes the scraper 44, causing the scraper 44 to move closer to one side of the electrode sheet 5. In other words, when the lamp strip 2 descends, the two electrode sheets 5 separate, and the scraper 44 moves closer to the electrode sheet 5 inside the lamp housing 1, which can effectively clean the surface of the electrode sheet 5, preventing dirt and foreign matter from appearing on the surface of the device when it is used in a humid environment, which could lead to poor contact after the lamp strip 2 is replaced.

[0030] In a preferred embodiment of this invention, a second spring 45 for resetting is provided on both sides of the scraper 44. A groove is provided on the inner side of the lamp housing 1, and the scraper 44 is slidably disposed in the groove, with the second spring 45 fixedly disposed on both sides of the groove. When the scraper 44 moves within the groove, the groove effectively guides the scraper 44. Simultaneously, as the scraper 44 approaches the electrode plate 5, the second spring 45 is gradually stretched. When the first spring 41 resets, the second spring 45 also resets simultaneously, ensuring that the scraper 44 is far from the electrode plate 5, thus avoiding poor contact between the two electrode plates 5 during subsequent replacements.

[0031] As a preferred embodiment of this invention, the bottom of the lamp housing 1 is provided with a storage groove 6 for placing the light strip 2. When the light strip 2 is installed in place, the light strip 2 can be located in the storage groove 6, so that the light strip 2 and the lamp housing 1 form a whole, avoiding the light strip 2 protruding and affecting the lighting effect.

[0032] As a preferred embodiment of this invention, the storage slot 6 has a slot on its side, and the light strip 2 has a protrusion on its side corresponding to the slot. When the light strip 2 needs to be replaced, the protrusion can be disengaged from the slot by prying it, making it easier and faster for the operator to replace the light strip 2 and improving the replacement efficiency of the equipment.

[0033] As a preferred embodiment of this invention, a sealing strip is provided at the connection between the light strip 2 and the storage groove 6. The sealing strip can effectively seal the connection between the light strip 2 and the lamp housing 1, preventing moisture and humidity from entering the lamp housing 1 and causing corrosion of the electrode sheet 5, further ensuring the electrical connection quality of the device, and ensuring the device's performance.

[0034] The working principle of this utility model:

[0035] When the light strip 2 is inside the lamp housing 1, the electrode plates 5 on the light strip 2 and the electrode plates 5 inside the lamp housing 1 are in contact with each other, keeping the light strip 2 energized. At this time, the light strip 2 can be used for illumination. When the light strip 2 is damaged and needs replacement, it is pulled out of the storage slot 6 by the protrusion. Since the magnetic block 42 on the light strip 2 and the magnetic block 42 at the bottom of the first spring 41 are magnetically attracted at this time, the first spring 41 is gradually stretched as the light strip 2 descends. When the light strip 2 descends, the electrode plates 5 on the light strip 2 and the electrode plates 5 inside the lamp housing 1 will separate. As the light strip 2 continues to descend, the push plate 43 on the bottom disc of the first spring 41 gradually descends. Since the push plate 43 is inclined, when the push plate 43 descends, it will push the two scrapers 44 closer together. When the scrapers 44 approach each other, their ends will adhere to the surface of the electrode sheet 5 inside the lamp housing 1. As the scrapers 44 move, they can scrape the surface of the electrode sheet 5, thereby removing foreign objects from the surface of the electrode sheet 5, preventing corrosion of the electrode sheet 5 surface when the equipment is used in a humid environment, and ensuring the stability of the connection in the later stage.

[0036] When the disc at the bottom of the first spring 41 contacts the bottom of the socket 3, the disc is blocked. At this point, continue pulling down the light strip 2. The magnetic block 42 on the light strip 2 separates from the magnetic block 42 on the disc, allowing the light strip 2 to be removed. When the two magnetic blocks 42 separate, the first spring 41 loses its tension and resets. Simultaneously, the second spring 45 on the side of the scraper 44 resets, causing the scraper 44 to move again to the side away from the electrode plate 5. Then, place the new light strip 2 at the bottom of the lamp housing 1, ensuring the magnetic block 42 on the light strip 2 aligns with the magnetic block 42 at the bottom of the first spring 41, thus completing the replacement of the light strip 2.

[0037] This invention allows for quick replacement of the light strip 2 by attaching it to the bottom of the lamp housing 1 and engaging with the insert rod on the light strip 2 through the insertion hole 3. Simultaneously, the two magnetic blocks 42 located inside the lamp housing 1 and the light strip 2 effectively ensure stability after replacement, preventing poor contact due to the light strip 2 not being properly secured. Furthermore, each time the light strip 2 is replaced, the downward movement of the push plate 43 effectively moves the scraper 44, cleaning the electrode plates 5 inside the lamp housing 1. This prevents corrosion of the electrode plates 5 in humid environments, avoiding subsequent contact issues and further improving the practicality and ease of use of the equipment. It also avoids the problem of the equipment becoming unusable due to the inability to replace the light strip 2.
