How about the current and voltage of the LED light source?
LED voltage, white light, green light and blue light are generally calculated by 3.2V, red light and yellow light are calculated by 2V.If it is small power, such as straw hats, bullet head, the current is calculated by 20MA,If it is a high power 1W, the maximum current is 350MA, and the current of 3W is 700MA.Lamp series voltage phase, constant current, if the voltage is constant, the sum of the current parallel.
No manual, have to connect the power to voltage, current source, from the beginning of the increase, to the brightest light source
It is best to find the instructions of the chip that encapsulates the light source. According to the above introduction, the voltage and current of the power supply can be calculated according to the series parallel mode of the circuit
