Problems solved by technology

Considering that such luminaires typically include multiple spatially separated SSL elements acting as point sources, which can lead to pixelation and glare in the luminous output of SSL-based luminaires, this is a far from insignificant challenge.

Embodiment Construction

[0035] It should be understood that the drawings are only schematic and not drawn to scale. It should also be understood that the same reference numbers are used throughout the drawings to indicate the same or similar parts.

[0036] figure 1 A cross-sectional view of a luminaire 10 according to an embodiment of the present invention is schematically depicted. The luminaire 10 comprises a carrier 11 such as a substrate, a printed circuit board (PCB) or the like serving as a surface 11 of the luminaire, on which a plurality of SSL elements 13 are mounted. Each SSL element 13 may be a single SSL element or a cluster of SSL elements grouped together such that during operation of the SSL element 13 the cluster gives the appearance of a single light source. The plurality of SSL elements 13 may be the same SSL element such that the luminaire 10 emits light having the same spectral composition from each of the SSL elements 13, however in alternative embodiments the luminaire 10 may...

Abstract

A luminaire (10) is disclosed comprising a plurality of spatially separated solid state lighting elements (13), each solid state lighting element associated with a lens element (17) arranged to shapea luminous distribution (21, 23) around an optical axis (14) of the solid state lighting element and at least one further optical element (19) arranged to redistribute at least part of a peripheral portion (23) of said shaped luminous distribution such as to reduce a perceived brightness of the solid state light element along a viewing angle coinciding with said peripheral portion.

Description

technical field [0001] The invention relates to a luminaire comprising a plurality of spatially separated solid state lighting elements, each solid state lighting element being associated with a lens element arranged to shape a luminous distribution around an optical axis of the solid state lighting element. Background technique [0002] Solid-state lighting (SSL), such as LED lighting, is rapidly gaining popularity due to its energy credentials and superior lifetime compared to traditional lighting (eg, incandescent, fluorescent, and halogen lighting). However, market penetration of such SSL appliances is not without challenges. For example, a serious challenge is to provide luminaires comprising SSL elements that provide the same visual experience as such conventional light sources. This is a far from insignificant challenge considering that such luminaires typically include multiple spatially separated SSL elements acting as point sources, which can lead to pixelation an...
