摘要： An illumination system comprises a light source optically coupled with an optical fiber (20). The optical fiber (20) includes a light emitting region extending along a portion of its length. The light emitting region includes a plurality of optical elements (30) disposed about a first longitudinal axis (38) extending along the surface of the optical fiber (20) and a plurality of optical elements (40) disposed about a second longitudinal axis (48) extending along the surface of the fiber (20). The second longitudinal axis (48) is displaced from the first longitudinal axis (38). In use, light from the light source is injected into the optical fiber (20) and propagates along the fiber according to Snell's law. A portion of the light propagating through the fiber (20) is reflected from the optical elements (30, 40) and is extracted from the fiber (20).

摘要： An optical fiber having a core is disclosed. A notch having first and second sides is formed in the fiber and extends into the core. At least the portion of the interior of the notch adjacent the first side has an index of refraction less than that of the core. Light travelling at a first angle to the fiber axis and striking the first side will be totally internally reflected if the first angle is greater than a predetermined angle. If the first angle is less than the predetermined angle, a portion of the light will enter the notch and emerge through the second surface making a second angle to the first surface, the second angle being greater than the first.
摘要翻译：公开了一种具有芯的光纤。在纤维中形成具有第一和第二侧面的凹口并延伸到芯中。与第一侧相邻的凹口的内部的至少部分的折射率小于芯的折射率。如果第一角度大于预定角度，则以纤维轴线第一角度行进并撞击第一侧的光将被全内反射。如果第一角度小于预定角度，则光的一部分将进入凹口，并通过第二表面出现与第一表面成第二角度，第二角度大于第一角度。
