Novel LED lamp

Abstract

The invention discloses a novel LED lamp which comprises a lamp holder structure with a lamp head base inside, a lamp cup with a mounting hole and a light emitting body structure, wherein the light emitting body structure is screwed into the mounting hole and is connected with the lamp head base in a screwed mode to be electrified. The lamp holder structure comprises an insulating lamp holder with the lamp head base inside and a connecting base. The light emitting body structure comprises a lamp head nut, an insulating hollow column, a driving device, a radiator, a ceramic isolation structure and an LED light source structure, wherein the lamp head nut can be screwed into the lamp head base to be electrified, the insulating hollow column is connected with the lamp head nut, the ceramic isolation structure is arranged on the radiator and made of ceramic materials, and the LED light source structure is fixedly mounted on the upper end face of the ceramic isolation structure. The ceramic isolation structure is arranged between the radiator and the LED light source structure so as to achieve the effects of heat conduction and dissipation and insulation. Internal threads are arranged on the inner side wall of the mounting hole of the lamp cup, external threads correspondingly adaptive to the internal threads are arranged on the outer side wall of the radiator, and the radiator can be fixedly arranged in the mounting hole through meshing and screwing of the internal threads and the external threads; meanwhile, the lamp head nut is synchronously screwed into and fixed in the lamp head base for electric connection.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a novel LED lamp.

The thermal conductivity and heat dissipation performance of the LED is poor, and the heat dissipation efficiency is low, which is not conducive to the co...

AI Technical Summary

Problems solved by technology

[0002] LED lamps are widely used due to their advantages of high lighting brightness, safety, energy saving and environmental protection. The lamp cups, radiators and other components of LED lamps on the market are generally made of heat-conducting and conductive metals. Leakage accidents in the structure of the LED light source will easily cause the lamp cups, radiators and other components that the human body can touch to be charged, and electric shock accidents will easily occur, and the safety performance is low.

In addition, parts that are accessible to the human body such as lamp cups and radiators of some existing LED lamps are made of insulating materials such as plastics. The thermal conductivity and heat dissipation performance are poor, and the heat dissipation efficiency is low, which is not conducive to the conduction and distribution of heat. After long-term work, it is easy to cause heat accumulation at the LED light source. If the temperature is too high, it will easily affect the working effect and service life of the LED light source.

In addition, the connection structure and connection method between the various components of the existing LED lamps are cumbersome and complicated, resulting in low assembly and disassembly efficiency, which affects the convenience of later inspection, maintenance and replacement work
