COB lamp bead is a kind of integrated circuit module (Chip On Board) lamp bead. Compared with the traditional single LED lamp bead, it integrates multiple chips in the same packaging area, which makes the light more concentrated and the light efficiency is higher. COB lamp beads can also better solve the problems of uniformity, color temperature consistency, and light spot brightness of traditional LED lamp beads.
Ordinary lamp bead refers to a single LED lamp bead, which has an independent package and structure. Compared with COB lamp beads, ordinary lamp beads can only accommodate one LED chip in the same packaging area, so the light efficiency is slightly lower than that of COB lamp beads.
In general, the main advantages of COB lamp beads are high brightness, high color temperature, high color purity, and good uniformity. They have been widely used in some high-quality lighting systems, smart home and automotive lighting. Ordinary lamp beads can be used in general lighting, signal lights, decorative lighting, signal lights and other fields.
