What are the specifications of SMD LED lamp beads?
5730 (5630) SMD LED lamp beads belong to Samsung's high-power structure, each 0.5W, the current is 100-150MA
3030 SMD LED lamp beads belong to Cree's high-power structure, each 1W, the current is 300-350MA, this structure also has 3W lamp beads (actually 2W, current 600MA)
The 3014 SMD LED lamp bead is of low power, each 0.1W, the current is 30MA, because the bottom heat is used, it is bigger than the conventional low power current.
2835 SMD LED lamp beads are low-power, each with 0.1W and 0.2W, and the current is 30MA and 60MA. Because of the bottom heat dissipation, it is larger than the heat dissipation area of 3014, so the current can be larger. Of course, we must also consider the chip size, and some people make 0.3W and 0.5W.
3528 SMD LED lamp beads are conventional low power, each 0.06W, the current is less than 20MA
5050 SMD LED lamp beads are conventional low power, each 0.06*3W, the current is less than 20*3MA, there are three chips inside, so the current is three times the conventional.
