发明名称 LIGHTING DEVICE COMPRISING A ROLL
摘要 A lighting device (30) and a method of manufacturing such a lighting device are provided. The lighting device comprises a sheet assembly (7), which comprises a substrate (1) being at least partly light transmissive, a plurality of light sources (5) coupled to the substrate. At least a portion of the sheet assembly (7) is fixed in a rolled-up arrangement so as to form a roll (12), whereby the light sources (5) in the portion of the sheet assembly (7) are arranged to emit light at least partly inwards in the roll and/or at least partly towards at least one end (31) of the roll. The present invention is advantageous in that it provides enhanced lumen density output, which makes the lighting device useful for high brightness applications, such as head lights and fluid purification.
