LIGHTING SYSTEM WITH IMPROVED ILLUMINATION DISTRIBUTION AND OUTPUT LUMINANCE VARIATION

摘要

Waveguides having improved illumination distribution and output luminance variation and lighting systems utilizing such waveguides are disclosed. The lighting systems generally include a light source which is optically coupled to a waveguide to distribute the light. The waveguides include one or more headlighting reduction regions and one or more output intensity shaping regions that work together to improve the distribution of light and reduce the effects of headlighting. The headlighting reduction regions may be integrated with the output intensity shaping region or may be an independent section.

1. A waveguide comprising:
at least one headlighting reduction region configured to reduce the magnitude of luminance modulation from the waveguide; and at least one output intensity shaping region configured to increase the uniformity of light distribution from the waveguide.
