Zusammenfassung:PURPOSE:To obviate the recondensation of a light emitting material by overcooling of a lamp and to stabilize the lighting state by providing a wind control means and preventing the direct collision of the wind from light shielding plates against the lamp. CONSTITUTION:A through-shaped mirror constituting a mirror structural body covering the bar-shaped lamp 1 consists of two sheets of long plate-shaped mirrors 3 disposed to leave a slit 31 on the side opposite to an irradiating port 22. The mirrors 3 are provided with a rotational driving mechanism for rotating the lamp 1 around the longitudinal direction thereof. The light shielding plates 20a, 20b constituted in such a manner that the wind from the port 22 of the lamp body 21 flows zigzag and arrives at the lamp 1 at the time when two sheets of the mirrors 3 rotated by this rotational driving mechanism shut off the emission of the light from the lamp 1 through the aperture of the lamp body 21 and the wind control means 29 which prevents the contact of the wind from the light shielding plates with the lamp 1 and pass the wind along the reflecting surfaces of the mirrors 3 ar installed to the mirror structural body. As a result, the recondensation of the light emitting material by the overcooling of the lamp is obviated and the lighting state is stabilized.
