Description

Technical Field

[0001] This utility model relates to lighting fixtures, and more particularly to lighting fixtures that can be extended and retracted to change length. Background Technology

[0002] One installation method for LED downlights involves installing a lamp holder on a wall or ceiling. A lamp base is installed at the bottom of the lamp holder to connect to the home's lighting circuit. The LED downlight head is then connected to the lamp base to complete the installation. This method relies on the lamp base and lamp base for both mechanical and electrical connections, eliminating the need for an additional spring arm on the downlight, making installation relatively simple. However, a problem exists: the lamp base's installation position is fixed. Therefore, to ensure a proper connection between the lamp base and the lamp base, the depth of the lamp holder needs precise control. If the depth is too deep, the lamp base cannot connect; if the depth is too shallow, a gap remains between the downlight and the mounting surface, which is unsightly. This places high demands on the depth of the lamp holder; once the depth is incorrect, it is difficult to remedy. Utility Model Content

[0019] To make the technical solution and features of this utility model clearer, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific examples. It should be understood that these examples are only for illustrating this utility model and are not intended to limit the scope of this utility model. After reading this utility model, any modifications of this utility model by those skilled in the art in various equivalent forms fall within the scope defined by the appended claims.

[0020] refer to Figures 1-7This embodiment provides an LED lamp, including a lamp body 1 and a lamp head 2. The lamp body 1 and the lamp head 2 are connected by a telescopic structure, so that the distance between the lamp head 2 and the lamp body 1 can be adjusted to change the installation length of the LED lamp to adapt to lamp tubes 3 of different depths.

[0021] The aforementioned telescopic structure includes: a first component 4 and a second component 5 coaxially arranged; the first component 4 has a first surface 41 extending in an arc shape and a second surface 42 concave relative to the first surface 41, to define a first radius R1 and a second radius R2 in the first component 4, the first radius being the distance between the first surface and the axis, and the second radius being the distance between the second surface and the axis; the second component 5 has a third surface 51 extending in an arc shape and a fourth surface 52 convex relative to the third surface 51, to define a first radius R1 and a third radius R3 in the second component 5, the first radius being the distance between the fourth surface 52 and the axis, and the third radius being the distance between the third surface 51 and the axis, wherein R1>R2>R3; and a guide groove is formed between the third surface 51 and the fourth surface 52, and a protrusion is formed between the first surface 41 and the second surface 42 that is inserted into the guide groove so that the fourth surface 52 is placed outside the second surface 42, the third surface 51 is placed inside the first surface 41, and the first component 4 and the second component 5 are movably connected along the axial direction. In other words, with the above arrangement, the first component 4 and the second component 5 can be nested together, with a portion of the first component 4 located inside the second component 5, and a portion of the second component 5 located inside the first component 4. Furthermore, the maximum outer diameter of both the first component 4 and the second component 5 is R1, and after nesting, the surfaces of the first component 4 and the second component 5 lie on the same arc surface.

[0022] In this embodiment, after the first component 4 and the second component 5 are adjusted to their relative positions, they need to be fixed in the adjusted positions. Therefore, the first component 4 and the second component 5 are fixed to their relative positions by friction, or by a limiting member. The limiting member can be any existing limiting structure, such as an elastic arm. When no external force is applied, the elastic arm opens to allow the second component 5 and the first component 4 to be in a limiting engagement; when an external force is applied, the elastic arm closes to release the limiting engagement between the second component 5 and the first component 4.

[0023] In this embodiment, one end of the first component 4 is connected to the back of the lamp body 1, and the end of the second component 5 away from the first component 4 is connected to the lamp head 2.

[0024] Furthermore, the lamp body 1 has a chamber for mounting the light source assembly 6, and a lampshade 7 is disposed at the opening of the chamber. A skirt 8 extends radially outward from the opening of the chamber.

[0025] During installation, first adjust the first component 4 and the second component 5 to the extended state, then insert the lamp holder 2 into the lamp tube 3 and connect it with the lamp base 9. After the connection is completed, push the telescopic structure to retract until the skirt abuts against the mounting surface, and the installation is complete.

[0026] The above is only one specific embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
