Description

Technical Field

[0001] This utility model belongs to the field of lighting fixture technology, and in particular relates to a detachable LED bulb. Background Technology

[0002] Existing screw-type LED bulbs are mostly designed and molded in a teardrop or cylindrical shape, and the bulb base assembly and bulb body are already connected and fixed at the factory during production. Figure 5 As shown, this results in a large space occupied by a single package during transportation, and secondly, it makes it impossible for users to disassemble and maintain the package during subsequent use to reduce usage costs.

[0003] Therefore, it is necessary to design a detachable LED bulb that is flat and easy to install and remove, so as to save packaging space during transportation and reduce the difficulty of installation and removal, allowing users to disassemble and replace it according to their needs, thereby reducing the cost of use. Utility Model Content

[0004] This invention provides a detachable LED bulb to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A detachable LED bulb includes a lamp holder assembly and a lamp body. The lamp body comprises a lampshade, an LED light source board, and a heat sink. The LED light source board is located on one side of the heat sink, while the heat sink with the LED light source board serves as a cover plate for the lampshade, embedded on its back. After the lampshade and heat sink are assembled, the LED light source board is located within the cavity formed by the lampshade and heat sink. The heat sink also has wiring holes and snap fasteners. A power wire is led out from the wiring holes of the LED light source board to connect to the lamp holder assembly. The bottom of the lamp holder assembly is designed and formed with an inverted buckle. The lamp holder assembly and the lamp body are movably assembled by screwing and / or snapping through the engagement of the snap fasteners and the inverted buckle.

[0007] Preferably, the inner side of the lamp head assembly can be designed and formed with a wire channel, and the wire channel is connected to the inverted buckle, which has a through hole for the power wire to be led out.

[0008] Preferably, the inverted through hole is provided with a conductive sheet, which is electrically connected to the power supply wire.

[0009] Preferably, the LED light source board can be provided with contact points to make electrical contact connection with the inverted conductive sheet.

[0010] Preferably, the lamp head assembly can be integrally molded to form a locking slot for mounting a spring locking plate.

[0011] Compared with existing technologies, the advantages of this utility model are:

[0012] This invention optimizes the lamp body structure in traditional light bulbs, simplifying and flattening it while ensuring stable operation. This saves on production materials and significantly reduces the space required for subsequent packaging and transportation. The easy-to-assemble and disassemble structure of the lamp head assembly also allows users to replace parts as needed, reducing operating costs. In addition, this invention can be fitted with a spring clip, allowing it to be used as a hanging light or an embedded ceiling light. Based on the snap-fit ​​assembly, it can be set up separately during packaging to reduce the space required for packaging.

[0013] Furthermore, this invention is small in size, thus requiring a small distance for light to escape. This reduces light loss during transmission and increases light energy to some extent. Furthermore, the structure itself reduces light loss. Experimental verification shows that, at the same power consumption, this invention achieves higher luminous efficiency compared to other larger bulbs, specifically approximately 5% higher luminous flux.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 6 As shown, this utility model is a detachable LED bulb, mainly comprising a lamp head assembly (1) and a lamp body (2). The lamp body (2) is characterized by comprising a lampshade (21), an LED light source board, and a heat sink (22). The LED light source board is disposed on one side of the heat sink (22), while the heat sink (22) with the LED light source board serves as a cover plate for the lampshade (21) and is embedded in the back of the lampshade (21). After the lampshade (21) and the heat sink (22) are assembled, the LED light source board is located on the lamp... The inner cavity is formed by the cover (21) and the heat sink (22); the heat sink (22) is also provided with a wire hole (220) and a fastener (221); the LED light source board has a power wire led out from the wire hole (220) to be connected to the lamp head assembly (1) in the circuit; the bottom of the lamp head assembly (1) is designed and formed with an inverted buckle (10); the lamp head assembly (1) and the lamp body (2) are assembled in a rotating manner by the cooperation of the fastener (221) and the inverted buckle (10).

[0026] This invention optimizes the lamp body structure in traditional light bulbs, simplifying and flattening it while ensuring stable operation. Figure 4 and Figure 5 With the same diameter, this invention can reduce the overall height, which is different from the traditional teardrop shape or similar design of light bulbs. Figure 5 With a similar cylindrical shape design, this utility model has flattened the lamp body (2) and the lamp head assembly (1) is detachable based on the screw-on movable assembly. In this way, it is no longer assembled and fixed when it leaves the factory, which can greatly reduce the space occupied for subsequent packaging and transportation. Since the lamp head assembly (1) is no longer fixed on the lamp body (2), its overall height can be reduced. When packaging, it can be laid flat with the lamp body (2) for packaging, which can save space. In addition, the easy-to-install and disassemble structure of the lamp head assembly (1) also allows users to disassemble and replace it according to their needs, thereby reducing the cost of use.

[0027] Check Figure 7It is understood that this utility model can be equipped with a spring clip, so it can be used as a hanging lamp or an embedded ceiling lamp. Based on the snap-fit ​​assembly, it can be set up separately during packaging to compress the space required for packaging.

[0028] See also Figure 8 This utility model provides another way for routing the power cord. Specifically, a wire-passing groove can be designed and formed on the inner side of the lamp head assembly (1). The wire-passing groove is connected to the buckle (10). The buckle (10) has a through hole for the power cord to be led out. The through hole of the buckle (10) needs to be equipped with a conductive sheet, and the conductive sheet is electrically connected to the power cord. Based on this setting, the LED light source board also needs to be equipped with a contact point to make an electrical contact connection with the conductive sheet of the buckle (10). In this way, when the lamp head assembly (1) is inserted into the lamp body (2), while rotating to lock it in place, the conductive sheet of the buckle (10) will also contact the contact point of the LED light source board, thereby realizing power supply and light emission.

[0029] Furthermore, this invention is small in size, resulting in a smaller distance for light to escape. This reduces light loss during transmission, increasing light energy to some extent. Furthermore, the structure itself reduces light loss. Experimental verification shows that, at the same power consumption, this invention achieves higher luminous efficiency compared to other larger bulbs, specifically approximately 5% higher luminous flux.
