Zusammenfassung:The utility model relates to the technical field of LED packaging, and discloses a ceramic lamp bead with uniform light emission, which comprises a ceramic substrate and a using device, and the using device comprises a positive electrode bonding pad, a negative electrode bonding pad, a point die bonding silver adhesive, an LED chip, a gold wire rod, an LED light source metal conductive gasket, an electrode welding point and an LED lens. Through two surface electrodes, a fluorescent glue layer, a gold wire rod, an LED light source metal conductive gasket, an electrode welding spot and an LED lens, through coating the fluorescent glue layer on an LED chip, improving the light color, using the gold wire rod, connecting the two surface electrodes and the electrode welding spot, and under the cooperation of the light source metal conductive gasket, a power supply is provided for light emitting of the LED chip. Due to the fact that the distance between the first wafer die bonding area Mark and the second wafer die
