Practical LED lamp

Abstract

The invention discloses a practical LED lamp, which comprises a lamp holder and a lamp holder arranged at the bottom of the lamp holder. The inner bottom of the lamp holder is provided with a cavity; The top of the screw rod is connected with the driver, and there is a sliding plate in the cavity. The two sides of the sliding plate extend into the sliding groove and are connected with the spiral pattern of the screw rod. The bottom of the sliding plate is provided with a connecting block, and the bottom of the connecting block runs through the bottom of the lamp holder. The walls are slidingly matched and connected. The interior of the connecting block is provided with a first groove body symmetrically on the left and right sides. The top of the first groove body is provided with a countersunk hole. There are through grooves in the blocks, the outer side wall of each through groove is matched with a second groove body, a first sliding block is arranged in the first groove body, and a first tension spring is arranged between the top of the first sliding block and the counterbore, The bottom of the first sliding block is provided with a sliding rod extending into the through groove; the invention has simple structure, convenient operation, stable insertion and high safety.

Description

technical field [0001] The invention relates to the technical field of lighting, in particular to a practical LED lamp. Background technique [0002] LED lights can be widely used in various indications, displays, decorations, backlights, general lighting and urban night scenes.

[0002] LED lights can be widely used in various indications, displays, decorations, backlights, general lighting and urban night scenes. LED lights play a very important role in people's daily life. With the development of science and technology, LED lights It has the characteristics of long life, energy saving and high efficiency, and is more and more popular among people. However, most of the LED lighting fixtures in the prior art do not have an electric shock protection structure. Users can easily touch the lamp holder when replacing the lamp holder or maintaining the lamp. Contacts in the seat, thus causing electric shock, causing accidents, resulting in personal and property losses. At the same time, the existing LED lights are generally connected by screwing power supply. The screwing process is cumbersome and laborious, and the power supply connection is relatively unstable. , It is very easy to have poor contact and lead to blind lights. Since LED lights are fragile items, they are easily damaged once the voltage is unstable, and the risk factor is high after damage. Emergency treatment devices should be installed to increase the safety during use.
