ABSTRACT:
An LED head includes a circuit board and a plurality of LED arrays aligned on the circuit board in a longitudinal direction of the circuit board. Each of the plurality of LED arrays includes a row of a plurality of first LEDs aligned in the longitudinal direction between a second LED and a third LED. The second and third LEDs are at the end of the row. The first LEDs have a width W1 in the longitudinal direction and the second LED and the third LED have a width W2 in the longitudinal direction. The width W2 is smaller than a width W1. The first, second, and third LEDs have the same dimension D in a direction perpendicular to the longitudinal direction. The first, second, and, third LEDs are aligned at predetermined intervals P1 and the plurality of LED arrays are aligned such that the first, second, and third LEDs are aligned in the predetermined intervals P1.
