INFLUENCE OF AMBIENT TEMPERATURE ON COLOUR PROPERTIES OF LOW-PRESSURE FLUORESCENT LAMPS
The article presents results of laboratory measurements of colorimetric parameters of various fluorescent lamps of different powers in ambient temperature ranging from +250 C to –250 C in steps of 50 C. Based on registered spectral distribution of radiation, correlated colour temperature and colour rendering index have been determined. Straight fluorescent lamps of 8 W, 18 W and 36 W powers were measured. In terms of 18 W fluorescent lamps, different lamp colour’s codes (640, 827, 840) were considered. Additionally, one straight frost-proof fluorescent lamp of 840 colour’s code and one 18 W compact fluorescent lamp integrated with a conventional magnetic choke have been measured. All straight fluorescent lamps cooperated with a conventional magnetic choke.
