a led light bulb

Abstract

The invention relates to an LED bulb. The LED bulb comprises a lamp holder, a bulb shell, a core column, an LED light source, a power source and protective gas, wherein the bulb shell is connected with the lamp holder; the core column extends into the bulb shell; the LED light source is located inside the bulb shell; and the power source is connected with the LED light source. The LED light sourceis mounted on the core column. The power source is mounted on the core column and located inside the bulb shell. A closed cavity is formed by the bulb shell and the core column. The protective gas islocated inside the closed cavity and comprises oxygen gas and helium gas, wherein the volume of the oxygen gas accounts for 1-50% of the total volume of the protective gas. According to the LED bulb,the connected LED light source, the power source and the core column are extended into the cavity of the bulb shell, and then the bulb shell is sealed; the LED bulb is convenient and fast to mount, high in mechanized production efficiency and low in production cost; and by means of the protective gas, the service life of the LED bulb is prolonged.

Description

technical field [0001] The present invention relates to the technical field of lighting, in particular to an LED light bulb. Background technique [0002] LED filament bulbs are widely used in the market due to their energy saving, environmental protection, long life and other characteristics. At present, the power supply of commonly used LED filament bulbs is installed inside the lamp holder to ensure that the LED bulbs can work normally. During the assembly process, the light source needs to be installed first Extend into the inside of the bulb, and then seal the bulb so that the sealed bulb matches the lamp cap, which facilitates the connection between the bulb and the lamp cap, then puts the power supply in the inner cavity of the lamp cap, and finally connects the cap with the cap. The process of this assembly method is loaded down with trivial details, and production efficiency is low, and production cost is high. On the other hand, the cost of the LED filament itself...

[0002] LED filament bulbs are widely used in the market due to their energy saving, environmental protection, long life and other characteristics. At present, the power supply of commonly used LED filament bulbs is installed inside the lamp holder to ensure that the LED bulbs can work normally. During the assembly process, the light source needs to be installed first. Extend into the inside of the bulb, and then seal the bulb so that the sealed bulb matches the lamp cap, which facilitates the connection between the bulb and the lamp cap, then puts the power supply in the inner cavity of the lamp cap, and finally connects the cap with the cap. The process of this assembly method is cumbersome, the production efficiency is low, and the production cost is high

On the other hand, the cost of the LED filament itself is relatively high. SMD lamp beads are used and sealed in the bulb. Both contain solder and PCB boards. Solder and PCB boards contain organic volatile substances, which are easy to accumulate inside the closed bulb. Organic volatile substances, organic volatile substances will pollute the LED lamp bead when the lamp is turned on at high temperature, causing the LED lamp bead to turn black, resulting in relatively large light decay and reducing the service life of the LED bulb. Therefore, it is necessary to propose a A new type of LED light bulb solves the above problems
