Abstract

PURPOSE:To prevent impurity gases from being generated from a reflector substrate after a lamp is completed by baking at least either a reflective film or a phosphor on a reflective surface side of a glass surface of the reflector substrate. CONSTITUTION:When an electrode 4 is always electrified and the while a voltage is applied selectively to a space between either one of a plurality of electrodes 13 and the electrode 4, discharge is generated in a discharge space 7 of a reflector substrate 5 formed between the electrode 13 and the electrode 4 of voltage application thereto. Lights of luminous colors in accordance with phosphors 11a to 11c on a reflective surface which faces this discharge space 7 are emitted from a display window 2 so that dissimilar luminous colors are obtained depending on the electrode 13 of voltage application thereto. Since the reflector substrate 5 is covered with a glass film 9, the phosphors 11 and the reflective film 10 are baked thereon without being oxidized. Therefore, impurity gases are prevented from being generated inside the lamp from the reflector substrate 5.

However, if a metal plate inside the envelope is generally used as a reflector and a phosphor is baked onto this reflective surface, the nickel will oxidize, and when the lamp is turned on, the oxidized nickel will be contaminated by electrons generated by discharge. Oxygen, which becomes a gas, is ejected, which impedes discharge and increases the lamp voltage.As a result, there is a problem in that the lamp malfunctions and the lamp life is shortened.

At least one of a phosphor and a reflective film may be baked on the reflective surface side of the glass film,
For example, if only the reflective film is baked, the phosphor may be glued onto the necessary location for emitting light, such as the inner surface of the display window, or the phosphor may be printed on top of the reflective film. It may also be printed on the image. That is, in a fluorescent lamp, it is possible for those skilled in the art to provide fluorescent bodies at required locations as described above, as necessary. The above-mentioned electrodes only need to have one anode and one cathode at a moment; for example, there may be a large number of only anodes. Therefore, the above-mentioned display fluorescent lamp has at least one of a reflective film and a phosphor on the reflective surface side of the glass film of the metal reflector base material, which is coated with a film that can be used for either AC lighting or DC lighting. Since one side is baked, no impurity gas is generated from the reflector base material after the lamp is completed.
