Abstract

PURPOSE: A fluroescent lamp, having high color rendering properties and high luminous efficiency with a slight color irregularity even on lightening for a long time, and prepared by coating the inner wall of a tube with a fluorescent substance mixture containing a specific green emission fluorescent substance.
CONSTITUTION: A fluorescent lamp containing (A) 25W55wt% green emission fluorescent substance of a borate fluorescent substance expressed by the formula (0.05≤a≤0.4; 0.05≤b≤0.6; 0.05≤c≤0.5; a+b+c<1), (B) 15W65wt% red emission fluorescent substance having a main emission wavelength of 600W640nm, e.g. yttrium oxide fluorescent substance activated with Eu3+, and (C) 5W45wt% a blue emission fluorescent substance having a main emission wavelength of 420W 470nm, e.g. a halophosphate fluorescent substance activated with Eu2+. Addition of 1W100wt% a halophosphate fluoroscent substance activated with Sb to the resultant substance provides a four color mixture composition, and other green emission fluorescent substances e.g. a silicate fluorescent substance activated with Mn having a main emission wavelength of 500W560nm, in an amount of 0.1W 30wt% based on the component (A) may be used.
