Abstract
A light source device (10) according to the present invention includes a first light source (1) and a first condensing member (2) that has a first opening (24) and that outputs output light from the first light source (1) through the first opening (24). The first condensing member (2) is constituted of a front condensing member (2a) that includes the first opening (24) and a rear condensing member (2b) that does not include the first opening (24). The rear condensing member (2b) is detachable from the first condensing member (2).
Claims10
1:
- light source device comprising:
- a light source;
- and
- an optical member that has an opening, has the light source disposed therein, and outputs output light from the light source through the opening,
- wherein the optical member includes an output member that includes the opening and a non-output member that does not include the opening, and
- wherein at least one component of the non-output member is detachable from the optical member.
3 more elements
2:
- The light source device according to claim 1, wherein the optical member has therein a reflective surface that is elliptical in cross section.
3:
- The light source device according to claim 1, wherein the at least one component has a contact surface and is attached to the optical member via the contact surface.
4:
- The light source device according to claim 3, wherein a center of the light source is disposed in a plane that includes the contact surface of the at least one component.
5:
- The light source device according to claim 1, wherein the non-output member is constituted of a single component.
6:
- The light source device according to claim 1, further comprising a cover that protects the light source.
7:
- The light source device according to claim 6, wherein the cover has a hole used for observing a light-emitting state of the light source.
8:
- An artificial sunlight radiation apparatus comprising:
- a light source device;
- a light guide member that receives light output from the light source device;
- a spectral adjustment member that adjusts a spectrum of light output from the light guide member and outputs artificial sunlight;
- and
- a light guide plate that radiates the artificial sunlight output from the spectral adjustment member onto a measured object,
- wherein the light source device is the light source device according to claim 1.
4 more elements
9:
- The artificial sunlight radiation apparatus according to claim 8, wherein the light source device further includes attaching means for attaching the light source device to the artificial sunlight radiation apparatus.
10:
- A method for maintaining a light source device, the light source device including
- a light source, and
- an optical member that has an opening, has the light source disposed therein, and outputs output light from the light source through the opening,
- wherein the optical member includes an output member that includes the opening and a non-output member that does not include the opening, and
- wherein at least one component of the non-output member is detachable from the optical member, the method comprising:
- a first removal step for removing the at least one component of the non-output member from the optical member;
- and
- a second removal step for removing the light source through an area of the optical member from which the at least one component is removed.
