摘要:
Articles and methods of making light redirecting film constructions including a microstructured optical film bonded in selected areas to another film, and including a diffuser are described. The diffuser has an optical haze in the range of (20) to (85) percent and an optical clarity of no greater than (50) percent. The diffuser may be a surface diffuser and may be an asymmetric surface diffuser.

Transfer tapes and methods of making transfer tapes are described. In one aspect, the transfer tape comprises a template layer having a structured surface; a backfill layer disposed on at least a portion of the template layer, the backfill layer having a microstructured surface opposite the structured surface; and a layer disposed adjacent the microstructured surface, wherein the layer disposed adjacent the microstructured surface has a refractive index that differs from the backfill layer. The microstructured surface together with the adjacent layer functions as a diffusive layer, or in other words a diffusive interface. Also described are microoptical glazing and methods of making microoptical glazing as well as insulated glazing units and methods of making insulated glazing units.

The invention relates to a light diffusion plate. The light diffusion plate according to one embodiment of the invention comprises a core layer formed with a thermoplastic resin containing diffusion agents and having an optical transmission property, and arranged in front of a light source; and a pattern layer configured with patterns formed on the surface of the core layer wherein the core layer is formed with a thickness of 0.5-4.0 mm, and the patterns are formed with a pitch of 0.5-3.0 mm, and a height of 0.1-2.0 mm. Accordingly, it not only obtains the optical feature with the same or more as that of the light diffusion plate according to the prior art, but also reduces the usage of the raw materials by the empty spaces occurring due to the curvature of the patterns constituting the pattern layer, thereby contributing to the weight reduction of the optical apparatuses and drastically reducing the usage of materials.

본 발명의 반사형 편광자는 종래의 분산형 반사 편광자에 비하여 휘선보임 현상이 개선되면서도 광시야각이 넓고 광손실을 최소화하면서도 휘도향상을 극대화광시야각이 넓고 광손실을 최소화하면서도 휘도향상을 극대화할 수 있다. 또한, 반사편광자 구현에 있어 단순 제어를 통해 그룹 분산체를 형성할 수 있어 공정간소화를 통한 생산성 향상을 극대화할 수 있다.
摘要:
A light redirecting member including a base layer (12), a reference plane (20) generally perpendicular to a first side of the base layer; and a plurality of optical elements (18) extending from the first side of the base layer, wherein at least one of the optical elements has a first surface (22) comprising a top inclusion angle between 18 degrees and 20 degrees relative to the reference plane and a second surface (24) comprising a bottom inclusion angle between 18 degrees and 20 degrees relative to the reference plane, wherein the top and bottom inclusion angles are selected to redirect incoming sunlight (50) upwardly (54) from a range of angular orientations during movement of the sun along a solar movement path.
