Abstract
An illuminator includes a strip-shaped light guide and a plurality of light sources. The light sources are disposed along one end surface in the width direction of the light guide to allow light to be incident on the one end surface. The light guide guides the light of the light sources from the one end surface to the other end surface in the width direction of the light guide. The one end surface and the other end surface of the light guide are light-diffusing surfaces. The width of the light guide is larger than the thickness of the light guide.
Claims4
An illuminator comprising:
- a strip-shaped light guide;
- and
- a plurality of light sources disposed along one end surface in a width direction of the light guide, the light sources allowing light to be incident on the one end surface,
- wherein
- the light guide guides the light of the light sources from the one end surface to the other end surface in the width direction of the light guide;
- the one end surface and the other end surface of the light guide are light-diffusing surfaces;
- and
- a width of the light guide is larger than a thickness of the light guide,
- the light guide part includes a horizontal strip-shaped light guide part, a vertical strip-shaped light guide part and a twisted strip-shaped light guide part which is continuous with one end in a longitudinal direction of the horizontal strip-shaped light guide part and connects the horizontal strip-shaped light guide part with the vertical strip-shaped light guide part,
- the twisted strip-shaped light guide part is twisted with respect to an axis extending in a longitudinal direction of the horizontal strip-shaped light guide part in such a way that directions of main surfaces of the horizontal strip-shaped light guide part and the vertical strip-shaped light guide part are different from each other with respect to the longitudinal direction of the horizontal strip-shaped light guide part, and
- the plurality of light sources is disposed over the horizontal strip-shaped light guide part, the vertical strip-shaped light guide part and the twisted strip-shaped light guide part in the light guide.
