PROBLEM TO BE SOLVED: To provide a light radiation device having a structure where a light source component is less likely to contact with a work main body when a protection component is replaced.SOLUTION: A light radiation device 100 includes: a body component 110; a light source component 161; a protection component 170; an internal space 101; a first support part 140; a second support part 150; a first replacement hole 121; and a second replacement hole 131. The body component 110 includes: body side walls 111, 112 and a body opening part 116. The body side walls 111, 112 form the internal space 101. The body opening part 116 forms parts of the body side walls 111, 112 and allows the internal space 101 to open to the exterior. The protection component 170 closes the body opening part 116 and may be coupled to or separated from the body component 110. The replacement holes 121, 131 respectively penetrate through the body side walls 111, 112, are formed at positions adjacent to the protection component 170, and have sizes such that the protection component 170 may pass therethrough. |
