UNIFORM LIGHT EXTRACTION FROM LIGHT GUIDE, INDEPENDENTLY OF LIGHT GUIDE LENGTH |
摘要 |
A light guide light extraction mechanism can be formed in a predetermined maximum length to yield a predetermined light emission characteristic. Any shorter length segment removed from a predetermined end of the extraction mechanism and installed in a light guide of that shorter length causes the shorter length light guide to exhibit substantially uniform surface brightness. This obviates the need for cumbersome trial and error development of a different light extraction mechanism for each such shorter light guide.
