In fact, LED in the laboratory is a DC-driven, DC drive no problem!
And in practical applications, the drive power can not do the desired effect!

The main problem is the constant current power supply, divided into two kinds of situation analysis:
1, with the external electrical match.
Mainly in: a, with the use of electronic transformers supporting the use of constant current chip peripheral circuit characteristics, resulting in unstable work. B, with a switch panel with indicator light when used.

2, LED lights themselves.
Main performance: a, constant current circuit peripheral circuit design is unreasonable, making the chip does not work properly lead to strobe. B, the lamp in the higher temperature environment, making the constant current chip lead to short-term protection caused by strobe.
