[1–8]. A perfect uniformity means that the luminous flux is spatially invariant. However, in prac- tice, there is always a degree of nonuniformity in the il- lumination field (Fig. 1). During design, the illumination system is simulated to quantify its lighting uniformity. Also, during ...

The calculation itself is a simple radiation transfer calculation based on the Lambertian emitter geometry, the cosine factor for Lambertian emission and also for incidence of light on a plane, as well as the well-known inverse square law. Using a general optimization algorithm, the spacing to th...

Symmetry arguments are used to reduce the complexity of the analysis in many cases. Of particular interest is how to select a lighting design to optimize the illumination uniformity across regions that can be described by simple geometric models, such as circles, squares, rectangles, regular ...
We explored the uniformity of light mixing, optical component design, and the directional orientation of the LED projection angles in a new LED lighting system design. To validate the design, we simulated the LED array performance using LightTools software with relevant parameters. The si...
Tunnel interior lightingTotal revealing powerEnergy savingOverall uniformityThe lighting requirement for both the visibility of critical object and preceding car to maintain traffic safety in the tunnel interior zone is considered. The visibility of the critical object depends on both road surface ...
A method for improving the uniformity of at least one optical property of a tiled OLED lighting source comprising at least two OLED tiles, the method comprising : applying electrical power to the OLED
In contrast to most of previous works in which the color and illumination uniformity of the pc-LED lighting systems were improved one by one, the developed scheme can improve both indicators simultaneously. To demonstrate the feasibility of the developed design scheme, an initially designed pc-LED...
