Abstract
Disclosed are optical composites with a first portion lens of light transmissive material and a second portion backing material which in various embodiments can be reflective, transflective, black, or patterned for visual effect. Non-transmissive backing materials used in optical arrangement embodiments can be utilized to confine and redirect light propagation and also to form mounting features such as flanges and tabs. Energy savings are achieved in optical arrangements with high optical efficiency utilizing compact, durable, and aesthetically appealing optical composites and lighting arrangements capable of providing an assortment of configurable angular light distributions.
Claims27
An optical composite comprising:
- A) a first portion comprising a volume of light transmissive material further comprising;
- 1) an output face having at least one lens curvature;
- 2) an internal cavity within the first portion with an input face formed by the boundary of the internal cavity;
- B) a second portion comprising a volume of backing material;
- C) at least one optically coupled interface between the first portion and the second portion.
The optical composite of P wherein the transflective material is comprised of dispersed regions of refractive index higher than the bulk material.
An optical arrangement comprising:
- A) an optical composite comprising;
- 1) a first portion comprising a volume of light transmissive material further comprising;
- a. an output face having at least one lens curvature;
- b. an internal cavity within the first portion with an input face formed by the boundary of the internal cavity;
- 2) a second portion comprising a volume of light backing material;
- B) at least one optically coupled interface between the first portion and the second portion;
- C) an LED board comprising at least one LED light source and a printed circuit board wherein the LED board is arranged to input light into the internal cavity such that light emitted from at least one LED light source enters the input face of the optical element.
