IRRADIATION BODY AND IRRADIATION DEVICE

摘要

PROBLEM TO BE SOLVED: To secure the maintainability of light emitting elements, and enhance the heat dissipation performance of the light emitting elements.SOLUTION: An irradiation body comprises: a board that is provided with light emitting elements; a first heat dissipating member that is provided in contact with the board, and that dissipates heat transmitted from the board; and a second heat dissipating member that includes a supporting part for supporting the first heat dissipating member, that is provided with an air suction passage for sucking the first heat dissipating member with negative pressure so that the supporting part comes into contact with the first heat dissipating member, and that dissipates heat transmitted from the first heat dissipating member.SELECTED DRAWING: Figure 5
