Abstract

A light-emitting arrangement (100, 600, 700, 800) is provided, comprising an elongated, at least partially transparent housing (101, 601, 701); an array (102, 602, 702, 802) of light emitting diodes (LEDs) (102a, 102b, 602a, 602b, 702a, 702b, 802a, 802b) arranged in a longitudinal direction within said housing; and an anisotropic scattering member (105, 605, 705, 805a, 805b) arranged within said housing, in the path of light from said light emitting diodes to said housing. The light emitting arrangement of the invention is particularly suitable for use in a fluorescent tube replacement lamp, since the anisotropic scattering member may reduce the spotty appearance associated with known LED-based TL replacement lamps, and it may also prevent or reduce problems with glare.
