摘要:
A light guide unit provided in this disclosure is used for performing a reversible optical conversion process on a light source. In an embodiment, the light guide unit is used for converting a planar light source into at least a linear light source, and then further to be converted into one point light source, while allowing beams emitted from the point light source to be guided and shot to a specific position by the use of a light-guiding element. Moreover, in another embodiment, the light guide unit is used for converting at least one point light source into at least a linear light source, and then further to be converted into a planar light source for emitting light. The light guide unit can be adapted for various applications, such as optical devices for illumination, entertainment, decoration or ornaments.
摘要:
An optical device includes: a lock having a locking unit and an actuation unit having at least one sensor and a reflective plate; and a key for the lock, configured with an unlocking unit having at least a light-guiding element for transmitting optical signals between the actuation unit and the unlocking unit. The actuation unit is activated to unlock the locking unit after the sensor detects and recognizes the optical signals. As the optical signals that are to be transmitted between the actuation unit and the unlocking unit can not be intercepted easily and also can be encoded, not only it is difficult to forge the key for the optical device of the present invention, but also the structural integrity of the optical device will not deteriorate easily after being used for a period of time. Therefore, the present invention is low in cost and has an excellent anti-theft effect.
