ABSTRACT:
A fluorescent lamp of the type comprising a U-shaped glass tube whose inside surface is coated with fluorescent materials and which is filled with mercury vapor and rare gas, two electrodes at the ends of the glass tube, and a cap or base which bridges between the ends of the glass tube. As compared with the incandescent lamps with the same wattages the luminous efficiency and lamp life are remarkably improved, and the fluorescent lamps may be made considerably compact in size.
