Abstract:
A plurality of LED circuits are each configured having white LEDs serially connected therein, and the white LEDs are arranged in alternate main scanning direction positions for each of the LED circuits. When any of these LED circuits has failed, an output light power of white LEDs of LED circuits that have not failed is increased by a light power control section, thereby compensating an extinguished amount of the failed LED circuit.
