Optical device for an optical element and apparatus employing the device

An optical device array comprising a plurality of optical devices in the array,

• wherein each of the plurality of optical devices for an optical element comprise:
• a light reflecting member,
• a resin member covering a light reflection surface of said light reflecting member, and
• a bumper member interposed between said light reflecting member and said resin member,
• said resin member including a boundary surface for reflecting light deviated from a predetermined region in front of said optical element, said boundary surface of the resin member or said light reflecting member being disposed such that light deviating from said predetermined region in front of said optical element and passing between said optical element and an external of said optical device is reflected more than once with each of said boundary surface and said light reflecting member disposed.

An optical apparatus comprising:

• An optical device array comprising a plurality of optical devices, each of the plurality of optical devices for an optical element comprise:
• a light reflecting member,
• a resin member covering a light reflection surface of said light reflecting member, and
• a bumper member interposed between said light reflecting member and said resin member,
• said resin member including a boundary surface for reflecting light deviated from a predetermined region in front of said optical element, said boundary surface of the resin member or said light reflecting member being disposed such that light deviating from said predetermined region in front of said optical element and passing between said optical element and an external of said optical device is reflected more than once with each of said boundary surface and said light reflecting member disposed in which said optical elements are so disposed that light deviating from said predetermined region in front of each of said optical elements and passing between each of said optical element and an external of each of said optical devices is reflected more than once with each of said boundary surface and said light reflecting member.

An optical apparatus comprising an optical element and an optical device for the optical element to control a light path about emission light emitted from the optical element to an external or incident light entered from an external to the optical element, said optical device comprising:

• a light reflecting member,
• a resin member covering a light reflection surface of said light reflecting member, and
• a bumper member interposed between said light reflecting member and said resin member,
• said resin member including a boundary surface for almost totally reflecting light deviated from a predetermined region in front of said optical element, said boundary surface of the resin member or said light reflecting member being so disposed that light deviating from said predetermined region in front of said optical element and passing between said optical element and an external of said optical device is reflected more than once with each of said boundary surface and said light reflecting member.

An optical apparatus including a plurality of light emitting elements composed of light emitting element chips or light emitting element modules in which said light emitting element chips are sealed by mold resins, and a plurality of optical devices controlling light paths about emission light emitted from said light emitting elements to externals, said optical devices each comprising

• a light reflecting member,
• a resin member covering a light reflection surface of said light reflecting member, and
• a bumper member interposed between said light reflecting member and said resin member,
• said resin member including a boundary surface for almost totally reflecting light deviated from a predetermined region in front of said light emitting element, said boundary surface of the resin member or said light reflecting member being so disposed that light deviating from said predetermined region in front of said light emitting element and passing from said light emitting element to an external of said optical device is reflected more than once with each of said boundary surface and said light reflecting member.
