LED LAMP DRIVING METHOD AND LED LAMP UNIT

摘要

PROBLEM TO BE SOLVED: To provide a method for driving an LED lamp that can obtain a greater luminescent color shift than that of a LED device by a current value change.

SOLUTION: The LED lamp comprises: the LED device of which a luminescent color is shifted to the blue end by a driving current value; and a fluorescent material that is excited by light emitted from the LED device and emits light by itself. In a method for driving the LED lamp, a color difference shift on a chromaticity diagram of the LED lamp is greater than a color difference shift on a chromaticity diagram of the LED device by changing the driving current value.
