摘要： A light diffuser, consisting of a holding mechanism and, releasably connected thereto, an inflatable sack that is at least partially translucent. The holding mechanism comprises an adapter ring that at one end serves for attachment to a spotlight and at the other end as a receptable of the sack. The adapter ring is closed off at the attachment end so as to be translucent and pressure sealed. At the holding mechanism means are provided for supply of a gaseous filling medium. Arranged at the adapter ring are a compressed-gas connection and an electronically actuatable valve for the gas supply, such that a first pressure sensor determines the increasing of pressure within the sack fixed to the ring and sends a switch-off signal to the valve when a preset maximal pressure value has been reached, in order to terminate or interrupt filling automatically.

摘要： A diffuser master is provided which is manufactured mechanically instead of holographically. The master can be made from a suitable substrate including relatively hard materials such as plastic, glass or metal. A substrate having a first side is worked to form a diffuser surface relief structure thereon. The substrate can be buffed using a buffing agent of a selected grit in order to form surface scratches in the first side of the substrate. The substrate can also be blasted with shot particles in order to form indentations and depressions in the first side. The substrate can alternatively be acid or alkali etched in order to form surface irregularities in the first side. The scratches, depressions or irregularities can be formed in order to create a desired surface relief and hence desired diffuser output characteristics.

摘要： An automatic testing illumination system has advantages of speed, quick calibration ability and therefore high accuracy over conventional illuminators. An spherical light source/concentrator exit port is rapidly and sequentially covered by at least one automated device for affecting the light leaving the exit port. Automation enables a very rapid sequencing of light onto a two or three dimensional array to cut the time for test and evaluation, and to permit very accurate calibration of the illuminator system.

摘要： A light diffusing film is produced by preparing a paint by adding a light transmissive diffusing material comprising resin beads to a light transmissive resin, and coating the paint on one or both of the surfaces of transparent film substrate made of TAC, to produce a light diffusing layer. In the light diffusing film, the haze value on the surface of light diffusing layer is three or more, the difference between the haze value along the normal and that along the lines ±60° apart from the normal is four or less, and the surface is practically smooth whose roughness is so adjusted as to give a surface roughness Ra of Ra≦0.2 &mgr;m. Application of such a light diffusing film onto a display panel inhibits scattering reflection which would otherwise cause the display to be whitish, reduces the variation of haze values which vary depending on the viewed angle, and thus improves display quality.

摘要： Light-reflective concave portions are disposed on the surface of a substrate. The concave portions have a first and second vertical section perpendicular to each other. The first vertical section has an internal shape defined by a first curve and a second curve, the first curve extending from one point on the peripheral edge of the concave portion to the deepest point of the concave portion, and the second curve extending continuously from the first curve and from the deepest point of the concave portion to another point on the peripheral edge of the concave portion. The average of the absolute value of an inclination angle of the first curve is larger than that of the second curve relative to the substrate surface. The second vertical section has an internal shape defined by a shallow curve and deep curves formed at both sides of the shallow curve.
