Abstract

A LED glass bulb includes a glass shade and an LED chip component. The LED chip component includes an LED chip, a first conductive pin, and a second conductive pin. The first and second conductive pins are spaced apart, the first conductive pin is connected to the LED chip via a first curved conductive strip, and the second conductive pin is connected to the LED chip via a second curved conductive strip. A first end of the glass shade is provided with a sealing connection base, the first and second conductive pins are embedded in and pass through the sealing connection base, and the LED chip, the first and second curved conductive strips are located inside the glass shade. The LED glass bulb can prevent damage to the LED chip during glass sintering sealing processes, thereby ensuring product quality, improving yield, increasing production efficiency, and reducing costs.
