[0002] In the field of household lamps, the bulb is one of the common lighting fixtures, which can be used for both household lighting and outdoor quick installation lighting. It is accepted by consumers for its simple overall structure, convenient installation, low replacement cost, low energy consumption and long life, especially for foreign users, small vendors and other groups, and is more widely used, and is also one of the mainstream export bulbs. As a kind of bulb, the T bulb is generally composed of a lamp holder, a lamp body, a lampshade and an internal lighting component. However, in the existing T bulb, the lampshade is generally directly installed on the lamp body, and a fixed connection is adopted between the two, resulting in a fixed overall height of the T bulb. When packaging and transporting it, the required packaging box height is large, the total transportation volume is small, and the production cost and transportation cost are high. Especially for import and export transportation, the number of items that can be transported at one time cannot be increased. Therefore, a T bulb shell that can reduce the overall height without much change in the basic appearance structure of the existing T bulb is needed. Summary of the invention

It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0022] like Figure 1 and Figure 2 As shown, a height-adjustable LED T-bulb lamp housing comprises a shell 7, a lamp holder 6 arranged at the top of the shell 7, and a lampshade 1 arranged at the bottom of the shell 7. The bottom of the shell 7 is provided with a circle of convex rings 2 protruding outwards, and the outer side of the shell 7 is provided with a telescopic ring 10. The open end of the lampshade 1 is provided on the telescopic ring 10. The diameter of the open end of the lampshade 1 is ≥ the diameter of the convex ring 2. The lampshade 1 can slide up and down along the outer wall of the shell 7 through the telescopic ring 10, and the telescopic ring 10 sliding downward is stopped by the convex ring 2.

[0023] The present application adds a convex ring 2 protruding outward on the outside of the bottom opening of the original shell 7. The convex ring 2 can not only improve the rigidity of the bottom opening end of the shell 7, making it less likely to deform during use and assembly, but also play a limiting role. When matched with the telescopic ring 10, the telescopic ring 10 sleeved on the outside of the shell 7 can be stopped by the convex ring 2 when sliding downward. At the same time, the diameter of the open end of the lampshade 1 is ≥ the diameter of the convex ring 2, and the open end of the lampshade 1 is installed on the telescopic ring 10. When the telescopic ring 10 moves up and down, it can drive the lampshade 1 to move up and down, thereby realizing the adjustment of the height of the entire lamp shell. When the lamp shell is contracted by the telescopic ring 10, the telescopic ring 10 can be stopped by contacting the convex ring 2 through the bottom of the lampshade 1 during the upward contraction process, thereby effectively solving the problem that the overall height of the existing LED T-bulb lamp cannot be adjusted, so that the box height required for the lamp is lower when packaging, and the total amount of lamps that can be transported at one time is larger during transportation and export trade. In the actual installation process, the diameter of the existing T-bulb lampshade 1 is increased, or the main body diameter of the shell 7 is reduced, so that the convex ring 2 at the open end of the shell 7 can be located in the lampshade 1, and the lampshade 1 is installed outside the shell 7 through the telescopic ring 10. When the T-bulb lamp needs to be used, the telescopic ring 10 slides down along the outer wall of the shell 7 to the convex ring 2 for limiting, so that the normal lamp shell state is realized for lighting use. When packaging is required, the telescopic ring 10 and the lampshade 1 slide upward along the outer wall of the shell 7, so that a part of the shell 7 is retracted into the lampshade 1, and the height of the entire lamp shell is easily reduced, so as to achieve the purpose of reducing the assembly height of the entire lamp. When the lamp is in use, the lampshade 1 can generally be extended by its own weight, thereby expanding the lighting area. When it needs to be reduced, it only needs to be placed on a plane, and the shrinkage can be basically achieved by the own weight of the shell 7, which makes it more convenient to shrink the lamp shell during packaging.

[0024] A further improvement is that at least two inwardly recessed limiting grooves 8 are provided on the outer wall of the shell 7, and a first positioning hole 11 is provided at the bottom of the limiting groove 8. The first positioning hole 11 is penetrated and arranged on the convex ring 2, and an L-shaped slider 9 is provided on the inner side of the telescopic ring 10. The shell 7 and the telescopic ring 10 slide up and down along the limiting groove 8 through the L-shaped slider 9. After being unfolded, the shell 7 and the telescopic ring 10 can be relatively locked and fixed by inserting one end of the L-shaped slider 9 into the first positioning hole 11.

[0025] During the assembly process, the cooperation of the limiting groove 8 and the L-shaped slider 9 can form a mutual limit between the housing 7 and the telescopic ring 10, avoiding the problem of mutual rotation between the two. At the same time, the trajectory is more accurate when sliding. During the unfolding and use of the lamp, after a certain force is applied to the telescopic ring 10 toward the convex ring 2, one end of the L-shaped slider 9 can be inserted into the bottom positioning hole, so that a mutual locking and fixing effect is formed between the two, avoiding the problem of easy up and down movement after unfolding, so that the lampshade 1 and the housing 7 have a certain relative fixing ability, and will not affect the packaging efficiency during packaging. Generally, the limiting groove 8 and the L-shaped slider 9 are used in two groups and are symmetrically arranged, the structure is simpler, and the performance can also be guaranteed.

[0026] A further improvement is that a plurality of reinforcing ribs 5 are formed on the outer wall of the shell 7 protruding outward along the height direction, an inwardly recessed slide groove 4 is formed between two adjacent reinforcing ribs 5, and a plurality of inwardly protruding guide sliders 3 are provided on the inner side of the telescopic ring 10. The guide slider 3 is arranged in the slide groove 4, and the telescopic ring 10 slides up and down along the slide groove 4 through the guide slider 3.

[0027] During the production process, a serrated structure is formed on the outer wall of the shell 7 along the height direction, so that a reinforcing rib 5 is formed in the outwardly protruding area, which can not only improve the strength and deformation resistance of the shell 7, but also naturally form a plurality of slide grooves 4. The guide slider 3 is located in the slide groove 4, so that when the telescopic ring 10 slides up and down along the outer wall of the shell 7, the guide slider 3 can form a mutual radial limit and sliding guide between the telescopic ring 10 and the shell 7, so as to avoid the situation that the telescopic ring 10 rotates with the lampshade 1, and can also better avoid the jamming phenomenon during telescopic extension. At the same time, the guide slider 3 can also play a role of cooperating with the convex ring 2 to limit the structure of the telescopic ring 10, so that the structure of the telescopic ring 10 can be simpler.

[0028] Further improvement is as follows: Figure 3 As shown, a downwardly protruding clamping column 12 is provided at the bottom of the guide slider 3 , and a second positioning hole 13 cooperating with the clamping column 12 is provided at the bottom of the limiting groove 8 .

[0029] When the guide slider 3 moves downward along the slide groove 4, the clamping column 12 can be inserted into the second positioning hole 13, thereby playing a role of mutual fixation, avoiding the problem of up and down movement after unfolding, and ensuring a certain relative fixation ability between the lampshade 1 and the shell 7.

[0030] As a further improvement, the bottom of the lampshade 1 is provided with an arc-shaped limiting chamfer, and the radius of the limiting chamfer is 8-15 mm.

[0031] Since a mainboard with an LED light-emitting patch will be installed at the bottom of the shell 7, in order to prevent the bottom surface of the existing lampshade 1 from sticking to the LED light-emitting patch when in the retracted state, an arc-shaped limit chamfer with a radius of 8~15mm is added to the bottom corner of the lampshade 1. The limit chamfer can form a sufficient spacing space between the bottom of the lampshade 1 and the lower end of the shell 7 in the retracted state, thereby making the lamp safer during transportation.

[0032] On the basis of any of the above technical solutions, it is further improved as follows: Figure 4 As shown, the shell 7 includes an upper base 15 and a lower base 18, the lamp head 6 is arranged on the upper base 15, the convex ring 2 is arranged on the lower base 18, the convex ring 2 is telescopically adjusted along the lower base 18, the upper base 15 and one side of the lower base 18 are connected by rotation, the other side of the upper base 15 is provided with a buckle 16, the lower base 18 is provided with a clamping hole 19 that cooperates with the buckle 16, and the lower base 18 is also provided with a wire hole 14, and the power line between the lamp head 6 and the lamp board is connected through the wire hole 14.

[0033] In the actual production process, the housing 7 is divided into an upper base 15 and a lower base 18 that are rotatably connected, and the two are connected by a buckle 16 and a clamp hole 19, which can make the assembly of the power cord between the lamp head 6 and the lamp board easier and more convenient, and the installation of the lamp board is more convenient, and when it needs to be opened and closed, it can be opened by pressing the buckle 16, and the operation mode is simpler. Among them, the limit groove 8 and the reinforcing rib 5 are both located on the lower base 18, which can make the structure of the upper base 15 simpler and make the demoulding of the upper base 15 and the lower base 18 more convenient.

[0034] As a further improvement, the lower base 18 is further provided with a battery installation slot 17 , and the battery installation slot 17 is located on the upper end surface of the lower base 18 , and the battery in the battery installation slot 17 can be replaced by opening the upper base 15 .

[0035] The current LED T-bulb lamp shell is generally powered by a power supply, which is relatively single. When there is a power outage or it is inconvenient to connect to the national power grid, the bulb cannot be used for lighting. For some countries and regions or outdoor users, it is easy to cause lighting difficulties. Therefore, a battery mounting slot 17 is set in the lower base 18. Through the design of the circuit board, when the lamp is connected to the power grid, the battery in the battery mounting slot 17 is in a charging or standby state. When the power of the national power grid is not connected, the battery in the battery mounting slot 17 can be used for power supply, thereby meeting the lighting needs. It is more flexible in use and effectively solves the problem of being unable to light due to lack of power when temporary power supply is needed.

[0036] The above-mentioned implementation modes are only preferred implementation modes of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present application shall fall within the scope of protection required by the present application.
