Abstract

An LED lamp comprises an LED lamp bead. The LED lamp bead comprises an LED chip and an LED electrode connected with the LED chip, and the LED chip is installed to an electrode support in a packaging mode. A sealing structure is utilized to seal the partial LED electrode exposed outside the electrode support to guarantee watertightness and insulation of the whole LED lamp bead. An independent airtight container is no longer needed for sealing the LED lamp, and therefore the structure of the LED lamp is simpler than that of an LED lamp in the prior art. In addition, according to the sealing method, the LED lamp bead is directly exposed outside, in an open ventilation state, luminescence with zero light loss can be achieved under the circumstance that auxiliary equipment is not needed, and meanwhile ventilation and heat dissipation of the LED lamp can be achieved in a maximized mode because of the open structure. Besides, each LED lamp bead where the sealing structure is adopted is independently provided with an independent radiator, and the radiators with the structures facilitate vertical convection of air. Therefore, the LED lamp is not only simple and practical in structure, but also better in heat dissipation effect and higher in light-emitting efficiency.

Description

【Technical field】 [0001] The invention relates to an LED lamp, in particular to a method for manufacturing an LED lamp using a novel sealing method and the LED lamp. 【Background technique】 [0002] In the traditional lighting technology, tungsten filament bulbs are mostly used. Due to the large power consumption and volume, low luminous efficiency and short life, they are increasingly unable to meet the needs of modern society. With the development of semiconductor technology, the application of LEDs with small power consumption and volume, high luminous efficiency and long life in electric light source technology has attracted more and more attention. [0003] With the advancement of technology, the application of light-emitting diodes (LIGHT EMITING DIODE, referred to as LED) is becoming more and more extensive, especially the power of LEDs is continuously improved, and LEDs are gradually extending from signal display to the field of lighting sources. In order to increase...
