1. LED lamp beads use low-voltage power supply, the supply voltage is between 2-4V, depending on the product, so drive it is a safer power supply than high-voltage power supply; especially suitable for public places;

2. Current: The working current is 0-15mA, the brightness brightens with the increase of current LED light beads have different brightness and different power. Light beads: general brightness of 60-70lm; bulb lamp: general brightness of 80-90lm. 1W red light, brightness is generally 30-40lm; 1W green light, brightness is generally 60-80lm; 1W yellow light, brightness is generally 30-50lm; 1W blue light, brightness is generally 20-30lm. Note: 1W brightness of 60-110lm; 3W brightness of up to 240lm; 5W-300W is an integrated chip, with series/parallel package, mainly depends on how much current, voltage, a few strings and a few.

LED lamp beads operating current as follows.

1, small straw hat-shaped, SMD 3528 and other 0.06W small power about 20mA, SMD 3014 small power 0.1W about 30mA;

2, SMD 2835, 5050 and other 0.2W in the power of about 60mA;

3, chip 2835, 5630, 5730, large core 5050 and other 0.5W medium power about 150mA;

4, a single 1W, 5050 lens package, mold top package, etc. about 350mA;

5, a single 3W about 1000mA;

6, a single 5W about 1500mA;

7, integrated LED module, it depends on the number of wafers and their combination mode (several strings and several parallel). power limit of LED beads 1. indicator LED beads are tested at 5mA, to green light working voltage voltage 3V, is 0.015 watts 2. small power lighting LED beads test current is 20mA, to white light 3.2V working voltage, is 0.064 watts 3. medium power Lighting LED beads more testing is 150mA, to 3.3V working voltage, is 0.495 watts 4. high-power lighting LED beads more testing is 350mA, to 3.3V working voltage, is 1.155 watts 5. More than this number is the LED integrated module or beads, at least by more than two LED chip assembly. LED chip maximum operating current and the use of power is dependent on the size of the chip cutting, luminous efficiency, support thermal conductivity and the overall condition of the lamp cooling environment to decide, only customary no strict absolutes.
