Abstract: Disclosed is a fluorescent glue for an LED lighting bar, and an LED bulb lamp, the fluorescent glue comprises a phosphor, a heat radiation material having a refractive index larger than 1.4 and a heat emissivity larger than 0.8, and a colloid, the heat radiation material accounts for 0.5% to 10% by weight of the fluorescent glue, the phosphor accounts for 25% to 45% by weight of the fluorescent glue, and the colloid accounts for 45% to 74.5% by weight of the fluorescent glue. The fluorescent glue combined with the heat radiation material can directly convert heat generated by an LED chip and the fluorescent glue into infrared waves that are radiated into the surrounding environment, without additionally providing a heat dissipating device or spraying a heat dissipating coating.

Abstract: Disclosed is an LED filament lamp using infrared radiation heat dissipation and an LED lighting bar thereof. The LED filament lamp includes a bulb shell, a core base with an exhaust pipe, a driver, a lamp cap, and at least one LED lighting bar with 2? light-emitting LED chip. The bulb shell and the core base are in vacuum sealing to form a vacuum sealed cavity filled with high heat conductivity gas; the LED lighting bar is located in the vacuum sealed cavity; one side of which is provided with a light-emitting layer of the LED chip, and the other side is provided with an infrared radiation converting layer; both ends of the LED lighting bar are fixed to the core base through a metal wire and connected to the driver; and the driver and the lamp cap are connected in series through an outer electrode leading-out wire.
