Abstract

See full text

A lighting device (2) comprises a light source (210) having a main forward emission direction (20), and an envelope (220) in which the light source (210) is arranged. The envelope (220) comprises an upper portion (225) having scattering properties and being arranged to reflect a part of the light from the light source (210) laterally and backwardly relative to the main forward emission direction (20) and transmit a part of the light from the light source (210). The light intensity distribution of the lighting device (2) is more uniform, as backward and lateral light intensity is increased while the light in the main forward emission direction (20) is still admitted.
