The light bar has a turning efficiency that determines the amount of light turned out of the light bar compared to the amount of light that continues to be guided within the light bar. The turning efficiency increases with distance from the first end of the light bar. The light guide panel is configured to receive light turned by the turning microstructure and directed out of the second opposite side of the light bar.
