| 摘要 |
A light conducting member transmits optical energy which is incident on one end thereof. The member is made up of a number of integrated light conducting cables which define the light incidence end of the member at one ends thereof. Each light conducting cable is formed in a truncated hexagonal pyramid or formed to define at least three surfaces thereof. The light incidence end of the light conductor is formed flat or to constitute part of a spherical surface or part of a conical surface.
