LED filament lamp using infrared radiation heat dissipation and LED lighting bar thereof

An LED filament lamp using infrared radiation heat dissipation, comprising:

• a bulb shell with an infrared transmittance larger than 0.8;
• a core base with an exhaust pipe;
• a driver;
• a lamp cap;
• at least one LED lighting bar with 2π light-emitting LED chip;
• the bulb shell and the core base are in vacuum sealing to form a vacuum sealed cavity and the vacuum sealed cavity is filled with high heat conductivity gas;
• the LED lighting bar is located in the vacuum sealed cavity, one side of the LED lighting bar being provided with a light-emitting layer of the LED chip, and the other side being provided with an infrared radiation converting layer;
• both ends of the LED lighting bar are fixed to the core base through a metal wire respectively, and are connected to the driver which is fixed below the core base;
• and the driver and the lamp cap are connected in series through an outer electrode leading-out wire.
