Filed:

Jun 28, 2018

Appl. No.:

16/021942

Inventors:

- Reading MA, US
Robert A. Gobron - Southborough MA, US
Anthony L. Bolzan - Boxford MA, US

International Classification:

G02B 27/09
G02B 15/16
G02B 6/122

Abstract:

In one aspect, a light-mixing system is disclosed, which includes a light pipe having an input surface configured for receiving light from a light source, a light-mixing segment optically coupled to the input surface, and an output surface optically coupled to said light-mixing segment through which light exits the light pipe. A putative vector normal to at least one of the input or the output surface forms a non-zero angle relative to a longitudinal axis of the light-mixing segment. In some embodiments, the non-zero angle can be, for example, about 90 degrees.

G02B 6/26

Abstract:

An optical system is disclosed, which comprises a glass light pipe having an input surface for receiving light from a light source and an output surface through which light exits the light pipe, and a polymeric light pipe optically coupled at its input surface to the output surface of the glass light pipe to receive at least a portion of the light exiting the glass light pipe, said polymeric light pipe having a textured output surface. A plurality of microlenses is optically coupled to said textured surface of the polymeric light pipe, and a projection lens is optically coupled to the output surface of the polymeric light pipe to receive light therefrom.

Abstract:

In one aspect, a lighting system is disclosed that includes a light pipe having an input surface for receiving light from at least one light source and an output surface through which light exits the light pipe. A lens doublet comprising two lenses is optically coupled to the output surface of the light pipe for receiving at least a portion of the light exiting the light pipe and projecting the light, e.g., onto a target surface. The lens doublet exhibits a chromatic aberration that is less than the chromatic aberration exhibited by the individual lenses of the doublet. In some embodiments, the lens doublet exhibits a chromatic aberration that is less than about 0.22 diopters for wavelengths over a range of about 450 nm to about 650 nm.
