FIELD: lighting.
SUBSTANCE: device (2) comprises a light source (210) having a main direct radiation direction (20) and a bulb (220) in which a light source (210) is located. Bulb (220) contains the upper land (225) scattering properties, and is placed to reflect light from a source (210) light and the main direct (20) radiation and to miss part of the light from a source (210) light.
EFFECT: distribution of the light intensity of the lighting device is more uniform, since the intensity of light in the opposite and lateral directions increases, while the light in the main forward direction of the radiation also passes.
