Abstract
A concavo-convex light emitting section provided on an under surface of a base material is formed of a synthetic resin with inorganic oxide dispersed therein. A larger amount of light is reflected by inorganic oxide having a large refractive index and dispersed inside the synthetic resin, to cause a plurality of light emitting sections to emit bright light with a small number of light emitting elements. A light guiding sheet capable of making bright and uniform illumination and a movable contact body using the same are realized with a simple configuration.
Claims9
A light guiding sheet comprising:
- a transmissive film-shaped base material;
- and
- a concavo-convex light emitting section formed on at least one side of the base material, wherein
- the light emitting section is formed of a synthetic resin with inorganic oxide particles dispersed therein.
A movable contact body comprising:
- a transmissive film-shaped base material;
- a concavo-convex light emitting section formed on at least one side of the base material;
- and
- a substantially dome-shaped movable contact made of a conductive metal sheet and mounted in correspondence with a position below the light emitting section, wherein
- the light emitting section is formed of a synthetic resin with inorganic oxide particles dispersed therein.
