Several specifications of commonly used LED patch lamp beads

SMDLED LED, also known as SMDLED, is a simple lamp whose luminous principle is to pass an electric current through a compound semiconductor, through the combination of electrons and holes, and excess energy will be released in the form of light to achieve the effect of luminescence.

LED chip lamp beads a total of 6730, 3030, 3014, 2835, 3528, 5050 and other specifications.

1, 5730 (5630) belongs to Samsung's high-power structure, 0.5W per unit, the current is 100-150MA.

2, 3030 is the high power structure of Cree, each 1W, using 300-350MA current, this structure also has 3W bulbs (actually 2W, current 600MA).

3, 3014 is a low power, 0.1W per piece, the current used is 30MA. Due to the use of bottom end heat dissipation, it is larger than traditional low power current.

4, 2835 is low power, each 0.1W and 0.2W. The current is 30MA and 60MA. Because the underside heat dissipation is used, the heat dissipation area is larger than the 3014, so the current can also be larger. Of course, consider the size of the chip. Some people also make it 0.3W and 0.5W.

5, 3528 is a traditional low power, each 0.06W, operating current within 20MA.

6, 5050 is also a traditional low power, each 0.06*3W, the use of 20*3MA below the current, there are three chips inside, so the current is also three times the traditional.
