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.
