Abstract

PURPOSE:To improve the color rendering of a lamp by the synergism with a material sealed in the luminous tube, in such means as to specifically determine the shape of the luminous tube. CONSTITUTION:On the inner wall of an outer tube 1 is coated a luminous film 3 that produces a maximum luminous emission in the range of wave length 610- 630nm. In the outer tube 1 a luminous tube 4 is supported and fixed by a support wire 5. The construction of a lamp is made in such a manner that relations of 0.65<=D<=0.95, 7<=80/piDla<=14, 2<=mHg<=13, 0.002<=mCd+mZn <=10, (0<=mCd, 0 <=mZn), 0.4<=le<=0.8 are established among the inside diameter of luminous tube Dcm, length lacm between electrodes 6, 7, length lecm from an end of the electrode 6 or 7 to the sealed part, and the amounts of mercury, cadmiun and zinc sealed in the luminous tube 4mHg, mCd and mZnmg/cc. repectively.
