PROBLEM TO BE SOLVED: To enable an LED lighting circuit for continuous lighting and an LED lighting control circuit for intermittent lighting to be configured as one circuit having a simple configuration, and enable simplification of wiring, miniaturization and reduction of the cost in an LED lighting circuit, an LED lamp, an LED lighting device and an energization control circuit for the same.SOLUTION: An energization control circuit (7A) is connected to an LED array series circuit including a first LED array (61) of first light emission color and a second LED array (62) of second light emission color different from the first light emission color which are connected in series between first and second input terminals (T5, T6) supplied with DC constant current. The energization control circuit (7A) includes, between the first and second input terminals, a switching element (70) connected to the second LED array in parallel, and a PWM control circuit (71) for turning on/off the switching element based on a predetermined frequency and a duty ratio.SELECTED DRAWING: Figure 1 |
