Projection glasses, projection temple structure, and modularize optical engine

A projection temple structure, comprising:

• a temple including:
• a wearing segment;
• an assembling segment arranged away from the wearing segment and configured to be detachably assembled to a frame, and
• a connection segment that connects the assembling segment and the wearing segment;
• and
• a modularized optical engine including:
• a light emitting mechanism embedded in the wearing segment, wherein the light emitting mechanism includes a light source unit configured to emit light and a control unit that is configured to emit an image signal;
• a projection mechanism embedded in the assembling segment and having a light output portion;
• and
• a connection mechanism having an optical fiber and an electrical wire that are embedded in the connection segment, wherein one end of the optical fiber is connected to the light source unit, another end of the optical fiber is connected to the projection mechanism, and the electrical wire electrically couples the control unit and the projection mechanism to each other;
• wherein the connection mechanism is configured to transmit the light and the image signal from the light emitting mechanism to the projection mechanism through the optical fiber and the electrical wire, respectively, so that the projection mechanism is able to project an image light from the light output portion.

A modularized optical engine, comprising:

• a light emitting mechanism including a light source unit configured to emit light and a control unit that is configured to emit an image signal;
• a projection mechanism spaced apart from the light emitting mechanism and having a light output portion;
• and
• a connection mechanism having an optical fiber and an electrical wire, wherein one end of the optical fiber is connected to the light source unit, another end of the optical fiber is connected to the projection mechanism, and the electrical wire electrically couples the control unit and the projection mechanism to each other;
• wherein the connection mechanism is configured to transmit the light and the image signal from the light emitting mechanism to the projection mechanism through the optical fiber and the electrical wire, respectively, so that the projection mechanism is able to project an image light from the light output portion.
