Title:
Light equipment
Document Type and Number:
Japanese Patent JP5947329
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a light source device in which enough longer life is achieved by suppressing the sputtering in a housing.SOLUTION: In a light source device 1, a control section sets the energy density of continuous laser light L on the surface of a metal structure 13 (electron radiation structure) while maintaining the laser support light lower than the energy density of the continuous laser light L on the surface of the metal structure 13 (electron radiation structure) while lighting the laser support light. Consequently, the metal structure 13 (electron radiation structure) is irradiated with energy density not causing any spattering of the metal structure 13 while maintaining the laser support light. Since sputtering can be suppressed in a light-emitting bulb 11 in the light source device 1, enough longer life is achieved.
