[0002] LED lamps are composed of a housing, a lamp panel and a power supply. At present, with the continued development of the industry, the leap forward in technology and the vigorous promotion of applications, the light efficiency of LED lamps is constantly improving and the price is constantly falling. It has the characteristics of energy saving and environmental protection, long life, low power consumption and easy maintenance, and can be widely used in various indication, display, backlight source, general lighting and other fields. LED lamps are also widely used in outdoor lighting and indication, such as mining lamps and spotlights that can provide powerful lighting effects. The above lamps are used outdoors in a harsh environment. Because they are affected by the external environment, their lifespan is usually difficult to achieve the ideal effect. Frequent repair and replacement of lamps will incur large manpower and material costs.

[0003] However, there are some problems with the prior art: outdoor LED lamps are generally installed at a high height. When inspecting or replacing them, it is necessary to use a ladder or stand at a high place to perform the operation, which poses certain safety risks. Since most LED lamps are fixed with screws, the operation is complicated and the operation time is increased. Therefore, we propose an LED lamp that is easy to replace. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide an LED lamp that is easy to replace. By designing the LED lamp to be plugged into a lamp tube and a lamp holder, and fixing it through a slot and a limit pin, the operation of installing and replacing the LED lamp is simpler and more convenient.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The lamp tube and the lamp holder are plugged in and fixed by the combination of the card slot and the limit pin. An avoidance groove, a slide groove and a card slot are provided in the lamp holder. When the connecting seat on the lamp tube is plugged into the lamp holder, the limit pin needs to be aligned with the avoidance groove. After the limit pin passes through the avoidance groove, the lamp tube is rotated to drive the limit pin to rotate into the slide groove until the limit pin slides into the card slot.

DETAILED DESCRIPTION

[0020] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown, an LED lamp that is easy to replace provided by an embodiment of the utility model includes a lamp holder 1 and a lamp tube 2, the lamp holder 1 is plugged with the lamp tube 2, a mounting groove 11 is provided at the upper end of the lamp holder 1, a fixing plate 12 is provided at the lower end of the lamp holder 1, the fixing plate 12 is used to fix the lamp holder 1, a connecting seat 31 is provided at the lower end of the lamp tube 2, an annular groove 21 is provided on the lamp tube 2, a sealing cover 22 is buckled on the annular groove 21, a lamp board 23 is provided inside the lamp tube 2, a limiting component 3 is provided inside the annular groove 21, and the limiting component 3 is used to fix the lamp tube 2;

[0022] Specifically, the connection seat 31 is disposed corresponding to the mounting groove 11 , and the connection seat 31 is plugged into the mounting groove 11 .

[0023] Furthermore, the lamp holder 1, as the main supporting component of the LED lamp, needs to be installed in a stable position. The lamp tube 2 is used to protect the lamp board 23 and the internal circuit, and at the same time provide a light propagation channel. In this embodiment, an annular groove 21 is provided inside the lamp tube 2, and a boss is provided outside the annular groove 21 to protect the limit assembly 3 inside. The shape of the lamp board 23 is set to be annular, sleeved on the outside of the annular groove 21, and bonded to the lamp tube 2. A lampshade is fixedly connected to the outside of the lamp tube 2 to protect the electronic components inside the lamp tube 2.

[0024] Furthermore, a sealing cover 22 is buckled on the annular groove 21 to prevent the limiting assembly 3 from being affected by the external environment, such as dust, rain, etc., which may cause the spring 34 and the limiting pin 35 to rust and be damaged, making it impossible to disassemble the lamp tube 2 and the lamp holder 1.

[0025] Specifically, the lamp holder 1 is provided with an avoidance groove 4 , the lamp holder 1 is provided with a slide groove 41 , the slide groove 41 is configured as a circular groove, and a clamping groove 42 is configured inside the annular groove 21 .

[0026] The avoidance groove 4 is provided corresponding to the limit pin 35 , the clamping groove 42 is provided corresponding to the limit pin 35 , the limit pin 35 is slidably connected to the avoidance groove 4 , the limit pin 35 contacts the slide groove 41 , and the limit pin 35 is plugged into the clamping groove 42 .

[0027] It should be noted that, due to the elastic force of the spring 34 inside the limiting hole 33, the limiting pin 35 is always in a tightened state, the clamping groove 42 is correspondingly arranged with the limiting pin 35, and the limiting pin 35 is just located inside the clamping groove 42 in the tightened state, and the outer diameter of the slide groove 41 is smaller than the clamping groove 42, so that there is a step at the connection position between the slide groove 41 and the clamping groove 42, so that the limiting pin 35 cannot rotate in a normal state, thereby achieving the fixation between the lamp tube 2 and the lamp holder 1;

[0028] In addition, a rounded corner is provided at the connection between the avoidance groove 4 and the slide groove 41 so that the limit pin 35 can enter the slide groove 41 more smoothly, thereby preventing jamming during installation and reducing the difficulty of operation.

[0029] Specifically, the limit assembly 3 includes a limit pin 35, a finger groove 32 is opened inside the annular groove 21, a limit hole 33 is opened on the connecting seat 31, a spring 34 is arranged inside the limit hole 33, the limit pin 35 is slidably connected with the limit hole 33, a shift block 36 is arranged on the limit pin 35, and an anti-slip pad 37 is arranged on the shift block 36.

[0030] Specifically, one end of the spring 34 is fixedly connected to the limiting pin 35 , and the other end of the spring 34 is fixedly connected to the limiting hole 33 . The shift block 36 is located in the finger groove 32 , and the end of the limiting pin 35 extends out of the limiting hole 33 .

[0031] Furthermore, when installing the lamp tube 2, pull the shift block 36, which will drive the limit pin 35 to slide toward the inside of the limit hole 33 and compress the spring 34. When the limit pin 35 is aligned with the slot 42, release the shift block 36, and the limit pin 35 slides toward the outside of the limit hole 33 under the elastic force of the spring 34, so that the limit pin 35 is always pressed against the slot 42 to prevent the limit pin 35 from falling off, causing the lamp tube 2 to fall off the lamp holder 1.

[0032] Working principle: During installation, first open the sealing cover 22 on the annular groove 21, pull the shift block 36, the shift block 36 drives the limit pin 35 to slide toward the inside of the limit hole 33, and compress the spring 34 to align the limit pin 35 with the avoidance groove 4, insert the connecting seat 31 into the installation groove 11, the limit pin 35 slides inward along the avoidance groove 4 until the connecting seat 31 completely enters the installation groove 11, rotate the connecting seat 31, the connecting seat 31 drives the limit pin 35 to rotate into the slide groove 41 until the limit pin 35 is aligned with the card slot 42, release the shift block 36, the limit pin 35 is subjected to the elastic force of the spring 34, and slides toward the outside of the limit hole 33, so that the limit pin 35 is always pressed against the card slot 42, and the replacement and installation are completed. The operation is simple and practical.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
