Title:
LIGHT IRRADIATION DEVICE FOR INSPECTION
Document Type and Number:
Japanese Patent JP2023018777
Kind Code:
A
Abstract:
To provide a light irradiation device 100 for inspection capable of realizing both drastic reduction in thickness and improvement in heat radiation.SOLUTION: A light irradiation device for inspection comprises: a housing 1 having an observation hole 1a for inspection that penetrates in a thickness direction; a first substrate 2 arranged around the observation hole 1a; and a plurality of LEDs 3 mounted on the first substrate 2, where the first substrate 2 is inclined so that a light emission direction of the LED 3 is different from an axial line C direction of the first observation hole 1a. The light irradiation device for inspection further comprises a second substrate 4 on which a resistance element 5 for limiting a current flowing through the LEDs 3 is mounted, where all or part of the second substrate 4 is separately arranged outside the first substrate 2 when viewed from the observation axial line C direction.SELECTED DRAWING: Figure 4
