PROBLEM TO BE SOLVED: To provide a method for lighting control of an LED lighting apparatus, which enables stable LED long-distance light control.SOLUTION: A method for lighting control of an LED lighting apparatus comprises: the step of performing LED lighting control with 0-100% of a rating capacity, in which a current signal of 0-20 mA is adopted for light-control signals of LED converters 9. The method further comprises the step of performing stepless control of LED lighting control with 0-100% of the rating capacity, in which a two-step push button switch 6 is adopted for an operation part. The method can be preferably used in application to lighting control of an LED lighting apparatus provided in a crane. The method further comprises the step of inputting light-control signals of 0-20 mA to the LED converters 9 connected in series to perform more than one kind of LED lighting control, whereby LEDs are collectively controlled in lighting with their wiring saved. |
