Abstract
A light-uniforming anti-glaring structure includes a light-polarizing reflection unit and a light-polarizing position adjusting unit. The light-polarizing reflection unit includes a multilayer reflector composed of a plurality of inter-stacked polymer films. One of the inter-stacked polymer films is a birefringence material layer that conforms to the condition of NX≠NY≠NZ, wherein NX is the index of refraction of light at X direction, NY is the index of refraction of light at Y direction, and NZ is the index of refraction of light at Z direction. The light-polarizing position adjusting unit is coupled with the light-polarizing reflection unit for adjusting the position of the light-polarizing reflection unit.
Claims21
A light-uniforming anti-glaring structure, comprising:
- a light-polarizing reflection unit including at least one multilayer reflector composed of a plurality of inter-stacked polymer films, wherein at least one layer of the inter-stacked polymer films is a birefringence material layer that conforms to the condition of NX≠NY≠NZ, wherein NX is the index of refraction of light at X direction, NY is the index of refraction of light at Y direction, and NZ is the index of refraction of light at Z direction;
- and
- a light-polarizing position adjusting unit coupled to the light-polarizing reflection unit for adjusting the position of the light-polarizing reflection unit;
- wherein the light-polarizing position adjusting unit includes a position adjusting ring surrounding the multilayer reflector for driving the multilayer reflector to rotate in 360 degrees, or for driving the multilayer reflector to flip-flop clock-wise or counter-clock-wise.
A light emitting device, comprising:
- a light emitting unit;
- a reflection unit located at one side of the light emitting unit, so as to reflect light beams produced by the light emitting unit;
- a light-polarizing reflection unit located at the other side of the light emitting unit, so as to receive or reflect the light beams from the light emitting unit, wherein the light-polarizing reflection unit comprises at least one multilayer reflector composed of a plurality of inter-stacked polymer films, wherein at least one layer of the inter-stacked polymer films is a birefringence material layer that conforms to the condition of NX≠NY ≠NZ, wherein NX is the index of refraction of light at X direction, NY is the index of refraction of light at Y direction, and NZ is the index of refraction of light at Z direction;
- and
- a light-polarizing position adjusting unit, coupled to the light-polarizing reflection unit for adjusting the position of the light-polarizing reflection unit;
- wherein the light-polarizing position adjusting unit includes a position adjusting ring surrounding the multilayer reflector for driving the multilayer reflector to rotate in 360 degrees, or for driving the multilayer reflector to flip-flop clock-wise or counter-clock-wise.
A light-uniforming anti-glaring structure, comprising:
- a multilayer reflector composed of a plurality of inter-stacked polymer films, wherein at least one of the inter-stacked polymer films is a birefringence material layer that conforms to the condition of NX≠Ny≠NZ, wherein NX is the index of refraction of light at X direction, NY is the index of refraction of light at Y direction, and NZ is the index of refraction of light at Z direction;
- and
- a position adjusting ring coupled to the multilayer reflector for driving the multilayer reflector to rotate in 360 degrees, wherein the multilayer reflector is divided into a plurality of reflector strips surrounded by the position adjusting ring, and each of the reflector strips is flip-flopped relative to the position adjusting ring.
