Abstract:
[PROBLEMS] To provide a light emitting unit which can efficiently emit light irrespective of opening window shape of a light emitting element substrate frame material, and a lighting apparatus, an image sensor and an image scanner using such light emitting unit. [MEANS FOR SOLVING PROBLEMS] The light emitting unit is provided with a light emitting element; a light emitting element substrate whereupon the light emitting element is mounted; and the light emitting element substrate frame material having an opening window for exposing the light emitting element. The inside of the opening window is sealed with a first resin and a second resin, and a ratio of the first resin to the second resin becomes smaller as it goes to a light emitting window external from the light emitting window inside. The first resin is a transparent resin and the second resin is a colored resin having a high luminosity or a resin including a light reflecting and/or scattering material. Since a cross section boundary between the first resin and the second resin is a curved line, among the light emitted from the light emitting element, the light reflected on an opening window bottom plane can be also efficiently projected to the external.
Abstract:
Disclosed is a light-emitting unit for illuminating devices which is excellent in heat dissipation performance. Specifically disclosed is a light-emitting unit comprising a light-emitting element, a light-emitting element substrate for mounting the light-emitting element, a light-emitting element substrate frame having an open window for exposing the light-emitting element, and an electrode for feeding electricity to the light-emitting element. This light-emitting unit is characterized in that the light-emitting element substrate is made of a metal and the light-emitting element is directly mounted on the light-emitting element substrate. The light-emitting unit is alternatively characterized in that the light-emitting element substrate is made of a metal, a metal oxide film is formed on the light-emitting element substrate, and the light-emitting element is mounted on an electrode formed on the metal oxide film.

Abstract:
[PROBLEMS] To provide a light guide in which unevenness in color does not take place even at a part close to the incident face. [MEANS FOR SOLVING PROBLEMS] A rod-like light guide (3) is produced by injection molding transparent resin such as acryl, and its surface comprises an exit face (3a), a bottom face (3b), right and left side faces (3d, 3c) and end faces (3e, 3f). One end face (3e) opposes a light emitting unit (10), and a light scattering pattern for scattering incident light from the end face (3e) is formed on the bottom face (3b). The light scattering pattern provides pattern shapes different between a portion close to the end face (3e) as the incident face and a portion separated from the end face (3e). The light scattering pattern (11) formed at the portion close to the incident face consists of a large number of fine hemispherical recesses whereas the light scattering pattern (12) separated from the incident face consists of triangular grooves or half-cut tubular grooves, and the axial direction of these triangular grooves or half-cut tubular grooves is the width direction (sub-scanning direction) of the pattern-forming bottom face (3b).
