why the constant current power of led can’t allowed to no-load?
The constant current power to ensure the stable currently , no matter how load .the paper takes the ideal mode as an instant to realize the support the claim. for example we has a constant current power as 1 ampere and 1 Ohm load resistance. the output voltage is 1 voltage. the constant current power gets output resistance and output voltage is infinity when output is open-circuit. at this time the constant current power will produce of high voltage. likely corresponding to increases in the rate of damage.
