LED LIGHT IRRADIATION DEVICE AND PRINTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an LED light irradiation device capable of efficiently cooling an inside of the device, and a printing device equipped with the same.

SOLUTION: The LED light irradiation device is provided with: a casing 3 having an inner space 2; a partitioning member 4 forming a first space 21 made and a second space 22 communicated with that 21 by partitioning the inner space 2; a control substrate 5 arranged in the first space 21; an LED substrate 6 arranged in the second space 22 with higher temperature than the control substrate 5; and an air flow generation device 31 for generating air flow in the inner space 2. The LED light irradiation device continuously flows air into the first space 21 and the second space 22 by operation of the air flow generation device 31.
