LED lighting lamp device stable in installation

Abstract

The invention discloses an LED lighting lamp device stable in installation. The LED lighting lamp device comprises an upper lamp body and a lower lamp body. A containing groove is formed in the bottom in the upper lamp body. First sliding grooves are symmetrically formed in the top in the containing groove left and right. A partition plate extending downwards is arranged between the two first sliding grooves. A downward extending section of the partition plate stretches into the containing groove. The parts, on the sides where the first sliding grooves are away from the partition plate, of the upper lamp body are internally provided with first cavities. The first cavities are internally provided with rotating shafts. Each first sliding groove is internally provided with a first screw in threaded connection with a push lock sliding block. The inner sides of the first screws are in power connection with a motor. First bevel gears are fixed to the rotating shafts in the circumferential direction. The upper portions of the first bevel gears are engaged and connected with second bevel gears. The parts, above the first cavities, of the upper lamp body are internally provided with second cavities. Second sliding grooves are formed in the inner sides of the second cavities. Second screws are arranged in the second cavities. The bottoms of the second screws penetrate the upper lamp body and are fixedly connected with the second bevel gears, and the second screws in the second cavities are in threaded connection with movable blocks.

Description

technical field

[0001] The invention relates to the technical field of LED lamps, in particular to a stably installed LED lighting device. Background technique

[0002] As a new type of lighting source, LED has become the development trend of a new generation of light sources due to its long life, high luminous efficiency, multiple light colors, one-time light distribution and directional irradiation functions, and the ability to work under safe voltages. Generally, LED light sources need to be equipped with radiators and power modules, and the power modules on the market are usually fixed on the radiators through screw connections. Although the structure of LED lamps assembled in this way is stable and reliable, the assembly of LED lamps is relatively cumbersome. The assembly efficiency is low. However, when installing and replacing general LED lighting products, it is necessary to cut off the power supply of the original lamps. If you forget to cut off the power supply o...
