Abstract: Systems, methods, and software to acquire light measurements in a targeted space using an autonomous vehicle, such as an aerial drone, are provided. Examples of targeted spaces include, but are not limited to, stadiums, arenas, racetracks, fields, parking lots, etc. Uses of such systems, software, and/or methods include, but are not limited to, verifying that required light intensity, distribution, camera image quality, and/or other performance metrics are met when commissioning, changing, checking, and approving lighting systems, among other things.

Abstract: A luminaire comprising: a light source in the form of at least one LED and a reflector, wherein a peripheral edge of the reflector defines a light exit opening on a side opposite the light source, wherein arranged in the light exit opening is a planar translucent cover wherein microstructures configured to direct and/or scatter light are distributed over the planar translucent cover. The planar translucent cover extends inwards in the direction of the light source, relative to an imaginary plane defined by the peripheral edge of the reflector.

Abstract: A reflector element and a method for manufacturing a reflector element are disclosed. In an embodiment the reflector element includes a plastic substrate and a silver layer arranged on the plastic substrate. The reflector element further includes a first barrier layer arranged on the silver layer, wherein the barrier layer has an at least 15 nm-thick oxide layer and a second barrier layer arranged on the first barrier layer, wherein the barrier layer includes siloxane, and wherein a thickness of the second barrier layer is at least 250 nm and at most 450 nm.
