Embodiment Construction
[0060] Hereinafter, embodiments of the light irradiation device of the present invention will be described.
[0061] figure 1 It is an explanatory sectional view showing the structure of an example of the light irradiation device of the present invention. The light irradiation device pairs along the horizontal direction ( figure 1 One side of the substrate W conveyed by the substrate conveying path L extending in the left and right direction ( figure 1 (middle is the upper surface) is irradiated with ultraviolet rays with a wavelength of 200 nm or less, has an opening for light emission formed on the lower surface, and has a substantially rectangular parallelepiped shape. The lamp housing 10 is provided with a partition wall 11 that partitions the interior of the lamp housing 10 up and down, thereby forming a lamp housing room R1 below the housing wall 11 and forming an electrical component housing room R2 above the housing wall 11 .
[0062] In the lamp housing room R1 ...
