Abstract

PURPOSE: To obtain satisfying value for spectrum evaluating factor while maintaing high light emission efficiency, by adding fluorescent member for compensating the light emission in blue-green region into three kind of fluorescent members of red, blue and green.
CONSTITUTION: Four kinds of fluorescent materials are coated on the inner wall of fluorescent lamp to form a light emitting layer 2. As the composition material of light emitting layer 2, strontium chloro-apatite activated by bivalent europium is employed for blue component, yttrium oxicide activated by trivalent europium for red component and barium strontium activated by bivalent europium for blue-green component.
