<p>Anode ends of LED arrays (1011, 1012) are shared. A constant-current circuit (1003) drives the LED array (1011) with a constant current, whereas a constant-current control circuit (3) drives the LED array (1012) by a method in which a pulse-based drive is applied to the drive based on the constant current.</p> |
