DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1-3, the present utility model discloses an LED T-bulb lamp housing with adjustable height, including a base 1. The top of the base 1 is fixedly connected with a lamp head 2, and the bottom of the base 1 is threadedly connected with a radiator 3. The bottom of the radiator 3 is provided with an annular slot 4, and a light source bracket 5 is tightly inserted into the annular slot 4. The bottom of the radiator 3 is installed with an inner cover cylinder 6 by screws, and the inner cover cylinder 6 covers the periphery of the light source bracket 5. The bottom of the radiator 3 is snap-connected with an outer lampshade 7. The outer lampshade 7 covers the outside of the inner cover cylinder 6 and is tightly sleeved with the inner cover cylinder 6. The bottom of the outer lampshade 7 is snap-connected with a cover 8. The main structural parts are connected by snap connection. The advantages of snap connection are easy installation, disassembly and maintenance, while maintaining high connection strength and having a certain degree of adjustability. The designed light source bracket 5, inner cover cylinder 6 and outer lampshade 7 structures have a certain telescopic adjustment function, which is beneficial to changing the height and shape of the bulb lamp according to the use needs or the number of LED lamp beads, thereby improving the aesthetics and adjustment performance of the lamp.

[0019] Specifically, the bottom end of the base 1 is provided with an external thread 9, and the top of the radiator 3 is provided with a threaded interface 10, and is connected with the base 1 through the threaded interface 10 and the external thread 9.

[0020] In this embodiment, through the cooperation of the threaded interface 10 and the external thread 9, the disassembly and assembly between the base 1 and the radiator 3 are convenient.

[0021] Specifically, a fan installation groove 11 is provided in the middle of the radiator 3, and a wire outlet hole 12 is provided at the bottom of the fan installation groove 11.

[0022] In this embodiment, the working principle of the radiator 3 is based on heat conduction and convection. By contacting with the electronic device, the heat generated by the device is quickly transferred to the surface of the radiator 3, and then the heat on the surface is transferred to the surrounding environment through natural convection or forced convection to achieve the purpose of heat dissipation. When high-power lighting is required, a cooling fan can be installed in the fan installation groove 11, so that the heat dissipation performance is doubled. The main function of the wire outlet hole 12 is to allow wires or cables to pass through for connection or extension in the device or system.

[0023] Specifically, the light source bracket 5 is of a cylindrical structure and is provided with reserved holes 13 thereon.

[0024] In this embodiment, the main function of the light source bracket 5 is to provide conduction and support. The light source bracket 5 is usually made of a material with good electrical conductivity, such as copper, for connecting the electrodes inside the LED lamp beads to ensure that the current can pass smoothly. In addition, the bracket also plays a role in supporting the LED chip, enabling it to be stably fixed on the bracket for subsequent encapsulation process.

[0025] Specifically, an annular clamping groove 14 is provided at the bottom of the radiator 3, and the outer lamp cover 7 is clamped on the annular clamping groove 14.

[0026] In this embodiment, the annular clamping groove 14 is an assembly structure for the installation between the outer lamp cover 7 and the radiator 3.

[0027] Specifically, the inner cylinder 6, the outer lamp cover 7 and the cover 8 are all made of transparent plastic, and the cross-section of the outer lamp cover 7 and the cover 8 after being joined is in a T shape.

[0028] In this embodiment, the functions of the inner cylinder 6, the outer lamp cover 7 and the cover 8 are to effectively protect the internal LED lamp from the external environment and maintain its performance and lifespan.

[0029] During use, the main structural components are connected by a clamping method. The advantages of clamping are easy installation, disassembly and maintenance, while maintaining a relatively high connection strength and having a certain degree of adjustability. The designed light source bracket 5, inner cylinder 6 and outer lamp cover 7 structures have a certain telescopic adjustment function (since the light source bracket 5 is inserted into the annular slot 4, by pulling the light source bracket 5, its size in the annular slot 4 continuously changes to achieve telescopic adjustment. Since the inner cylinder 6 and the outer lamp cover 7 are sleeved with each other, by pulling the outer lamp cover 7, it moves up and down along the track of the inner cylinder 6 to achieve telescopic adjustment), which is beneficial to changing the height and shape of the bulb lamp according to the usage needs or the number of LED lamp beads, thereby improving the aesthetics and adjustment performance of the lamp.

[0030] In summary, for this height-adjustable LED T-bulb lamp housing, the main structural components are connected by a clamping method. The advantages of clamping are easy installation, disassembly and maintenance, while maintaining a relatively high connection strength and having a certain degree of adjustability. The designed light source bracket 5, inner cylinder 6 and outer lamp cover 7 structures have a certain telescopic adjustment function, which is beneficial to changing the height and shape of the bulb lamp according to the usage needs or the number of LED lamp beads, thereby improving the aesthetics and adjustment performance of the lamp.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
