The invention provides a luminaire (100) comprising an array (102) of light exit windows (104, 104′, 104″, 204, 304′, 304″, 404′, 404″, 604, 804′, 804″, 804′″, 904′, 904″, 1004, 1004′, 1004″), wherein each light exit window comprises a material adjustable between at least a first state having a first translucence and a second state having a second translucence and an electrode arrangement (112) for adjusting said translucence of the material. Such a luminaire (100) can provide differing lighting effects whilst providing illumination and, additionally, differing aesthetic effects when viewed under ambient lighting. There is also provided a method of configuring the luminaire (1100), a computer program product for implementing the method (1200), a computing device including the computer program product (1300) and a lighting system comprising the luminaire (100).

A mount for a light assembly in a luminaire has a base section and mounting arms upstanding from the base section. Each mounting arm has an upward length and a width and has a lower portion and an upper portion. Mounting pads for light sources are unitary with or attached to the mounting arm upper portions and have an upward length and a width. The width of the mounting pads extends in a direction oblique to the width of the mounting arm lower portions. Preferably, the length of the mounting pads extends in a direction oblique to the length of the mounting arm lower portions. Light sources mounted on the mounting pads may emit beams of light directed obliquely away from each other and obliquely towards the base.

A HubblePerkinElmer correcting mirror for luminaries intended to illuminate a room, where the luminaries may send direct bright light towards directions that are inconvenient. Similarly to its space telescope device, the HubblePerkinElmer correcting mirror redirects the emitted light to other directions that are more advantageous for illumination, particularly to avoid direct bright light onto the eyes of humans in the space.

An omnidirectional LED filament holder and lighting device comprising the same comprises a filament tree supporting a plurality of linear LED filaments having a twisted orientation relative to a central support stalk of the filament tree. When arranged within a globe of a lighting device, the omnidirectional LED filament holder provides a lighting device providing omnidirectional light emission usable for general lighting applications while providing a desirable aesthetic for the lighting device.

The back plate has four lateral walls and a bottom plate. A back side of the bottom plate includes multiple sets of folding hooks. Each set corresponds a different installation platform. One of the multiple sets of folding hooks is folded to be used for hooking to a corresponding installation platform. The light source module has multiple LED modules disposed on the bottom plate. Each LED module has a LED device and a lens. The lens diffuses a light of the LED device to be evenly emitted from the lens and broadening an output angle of the light via the lens. The diffusion plate with a peripheral edge is fixed to the four lateral walls of the back plate. The driver cover is attached to an external side of one of the four walls of the back plate. The driver cover defines a container cavity for concealing the driver module.

A plurality of LEDs (104) is mounted only onto said first main surface (105) and configured to emit LED light (107). An encapsulant (108, 114) covers the plurality of LEDs (104) and at least part of said first main surface (105).
