摘要： A luminaire and method are provided comprising a light source, a plurality of prisms, such as linear prisms, for redirecting light from the light source in a predetermined direction, and a reflector for redirecting light from the light source toward the plurality of prisms. Each of the linear prisms has a longitudinal axis and the light source has a longitudinal axis, wherein the longitudinal axes of the linear prisms are substantially parallel to the longitudinal axis of the light source. Each of the plurality of prisms has an included angle, which can vary as a function of the distance from the light source. The angle can vary stepwise or continuously. In one embodiment, each of the plurality of prisms adjacent the light guide has an included angle in the range of between about 35 and 45 degrees. In another embodiment, the included angle is substantially uniform among the prisms. The luminaire optical sheet can be made out of continuous sheet with built in hinge points to provide a complete light redirecting structure.

摘要： Retroreflective sheeting for forming orientation free cones of reflected light encompassing a 0.5 degree angle of observation is formed of small metal backed cube corner prisms in an array in which the size of the prisms are in a range between 0.0005 inch to 0.003 inches on center. The array is formed by casting transparent plastic prisms in a mold formed by ruling three sets of grooves which intersect at an angle. The grooves are spaced apart in the range of 0.0005 inch to 0.003 inches on center. Before or after formation, the prisms are coated with a reflective material such as a metal.

摘要： A retroreflective material providing a visual coloration includes a body member with microprisms on its rear surface. Some of the microprisms have a retroreflective interface and the remainder have a colored non-reflective coating thereon. As a result, light rays entering the front face which impinge upon the prisms with the retroreflective interface are redirected so that they exit the material in a parallel path. Light rays which travel to the color coated prisms are refracted from those prisms and impart a visual coloration to the material in daylight and ambient light.

摘要： A retroreflective laminar sheet assembly comprises base and cover sheets made from flexible synthetic plastic materials, and an array of interposed retroreflective film pieces seated within discrete cells formed therebetween. The sheets and film pieces of different compositions are used to afford a preselected balance of mechanical and optical properties, and the construction is such that distortion is minimized and flexibility of the assembly is maintained. The invention also provides novel methods by which such an assembly can be produced, which may take advantage of inherent or induced cohesive characteristics of the components employed.

摘要： There are disclosed an apparatus and a method for continuously embossing synthetic plastic sheet material with precisely formed embossments in patterns repeating along the length thereof. The apparatus includes a movable polished belt upon which the sheet material is carried, and a series of molds are placed on the sheet material. As the sheet material and molds are advanced in steps through the apparatus, presses clamp the molds and belt against opposite surfaces of the sheet material and raise the temperature of the assembly to embossing temperature for the resin to cause the resin to flow into the mold cavities, and volatiles at the interface are dissolved in the resin. After the embossing step, the clamping pressure is released and this permits limited shrinkage of the mold and sheet material. At subsequent stations, controlled temperature reduction is effected, and limited shrinkage is permitted after the clamping pressure is released at each station and as the material and molds move to the next station. Mold distortion is thus avoided and the embossments remain precisely formed.
摘要翻译：公开了一种用于连续地压印合成塑料片材的装置和方法，该塑料片材具有精确成形的压花，其图案沿其长度重复。该装置包括可移动的抛光带，载带有片材，并且一系列模具放置在片材上。当片材和模具通过装置逐步推进时，将模具和带压紧到片材的相对表面上，并将组件的温度提高到树脂的压纹温度，使树脂流入模腔，界面处的挥发物溶解在树脂中。在压花步骤之后，夹紧压力被释放，这允许模具和片材的收缩受到限制。在随后的站点，控制温度降低，并且在每个站点释放夹紧压力之后以及当材料和模具移动到下一个工位时允许有限的收缩。因此避免了模具变形，并且压花保持精确地形成。

摘要： A retroreflective structure is described in which an array of transparent prisms is formed on a release coating of a sheet. The facet side of the prisms is made reflective and the prisms are either released to form a plurality of individual retroreflective structures or the array is adhered to a supporting substrate and then released from the base sheet. In the latter case, the array can be applied to a pre-existing structure formed of compatible fabrics, such as tarpaulins.

摘要： A durable reusable polymeric mold for casting a microstructure sheet having an array of prism elements and a method for forming the microstructure sheet are disclosed. A polymeric mold has a facet side and a base side including an array of prism elements upon which an radiation cured sheet can be formed. A protective surface layer can be formed on the facet side of the polymeric mold. The protective surface layer is sufficiently opaque to radiation to protect the polymeric mold from damage when the curable sheet is formed and is sufficiently bonded to the polymeric mold to allow the cured sheet to be removed from the protective surface layer while not substantially removing the protective surface layer from the polymeric mold. The microstructure sheet can be used as a retroreflective structure.

摘要： A retroreflective assembly includes a transparent polycarbonate housing of generally trapezoidal cross section. A channel extends upwardly from the base of the trapezoid, and the channel receives a vertically oriented strip of retroreflective sheet material. Planar side surfaces are provided at an angle with the vertical so that light from oncoming cars impinging on it will be directed downward to the retroreflective strip, whose top is spaced downward from the top of the housing to permit a thickness of material between the top of the channel on the top of the housing that is sufficient to afford structural strength to the housing. As a result, the image of the retroreflective strip is higher than its actual position, permitting relatively high visibility in a small structure of rugged construction.
