|MODELLING THE LUMINOUS INTENSITY DISTRIBUTION CURVE OF FLUORESCENT LAMPS WITH AN INTERNAL REFLECTOR|
Fluorescent lamps with internal reflectors are a modern type of fluorescent light sources, in which the luminous flux is emitted only through a sector of the light emitting tube's surface. The study presents the method for calculating luminous intensity curves for two type of reflector fluorescent lamps, in which the reflecting layer is deposited onto the inner side of the main light emitting tube or onto an additional tube with the diameter of 38 mm, inside of which there is a typical fluorescent lamp with the diameter of 26 mm. The influence of construction parameters on the calculated luminous intensity curves was also studied.
