Combined LED lamp capable of avoiding short circuit

Abstract

The combined LED lamp capable of avoiding the short circuit comprises an arranged lamp holder, mounting grooves are symmetrically formed in the top of the lamp holder, lamp bodies are mounted in the mounting grooves, and glass covers are mounted on the outer sides of the lamp bodies; a micro motor is installed in the middle of the inner side of the lamp holder, the output end of the micro motor is connected with a shaft rod, the middle of the shaft rod is sleeved with a first reciprocating lead screw, and a first ratchet wheel assembly is connected between the first reciprocating lead screw and the shaft rod; a movable cavity is formed in the lower portion of the inner side of the lamp holder, sleeve rods are connected to the two sides of the movable cavity, and pressing plates are fixed to the sleeve rods; moving grooves are formed in the front side and the rear side of the top of the lamp holder, second reciprocating lead screws are connected into the moving grooves through bearings, and the second reciprocating lead screws are sleeved with cleaning frames. The combined LED lamp capable of avoiding the short circuit is good in sealing performance, avoids the short circuit caused by damp, can be conveniently and rapidly installed and fixed, and meanwhile can perform external dust cleaning and internal heat dissipation treatment in long-term use.

Description

technical field [0001] The invention relates to the technical field of LED lamps, in particular to a combined LED lamp that avoids short circuits. Background technique [0002] LED is a solid-state semiconductor device that converts electrical energy into visible light. It has many advantages such as high brightness, environmental protection and energy saving, long service life, stable performance, low energy consumption, and rich colors. It has gradually replaced traditional lamps such as tungsten lamps. The field has a wide range of applications, and most of them use combined connection methods. However, the existing combined LED lamps still have the following problems in the process of use: [0003] The joint between the existing combined LED lamp and the lamp holder is poorly sealed. When the LED lamp works in the open air for a long time, the humid air is easy to contact the circuit between the LED lamp and the lamp holder, which may easily lead to a short circuit of th...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a combined LED lamp that avoids short circuit, to solve the problem that the existing combined LED lamps on the market have poor sealing performance and are prone to short circuit due to moisture, and are not convenient for convenient installation and fixing. It is inconvenient to clean the external dust and internal heat dissipation during long-term use
