Abstract (en)
[origin: EP2628998A2] The light for rectangular surfaces comprises a plurality of light emitting diodes (1) arranged in a row, including each one of said light emitting diodes (1) its corresponding optics (3, 4) and characterized in that some of said light emitting diodes (1) comprise asymmetric optics (3) and the remaining of said light emitting diodes (1) comprise extensive asymmetric optics (4). It allows for optimising the quantity of light emitting diodes for rectangular spaces, because the majority of light is incident on the shelf or site to be illuminated and has low losses, which is a differences in respect of currently known light using not very asymmetric optics, which causes an intensive illumination or a large loss of light if they are further apart from the surface to be illuminated.
