Description of the Related Art A fluorescent lamp is a glass tube in which a phosphor film (layer) is formed, in which mercury and argon gas are enclosed, and is characterized by a simple structure and efficient and bright fluorescent light emission. have. Generally, fluorescent lamps include a low-pressure mercury discharge lamp using low-pressure mercury vapor and a high-pressure mercury discharge lamp using high-pressure mercury vapor. A high-pressure mercury discharge lamp has a high temperature in the glass tube (inner tube) that emits visible light to ultraviolet rays, so a double tube with an additional glass tube (outer tube) outside this glass tube (inner tube) There is also a structure in which a phosphor film is formed on a part of the inner wall of the outer tube.

れるという差異がある。In the low-pressure mercury discharge lamp, most of the ultraviolet rays from the mercury vapor are converted into visible light by the phosphor layer, whereas in the high-pressure mercury discharge lamp, the visible light emitted from the mercury vapor directly serves as the light source and is changed by the phosphor layer. The difference is that fluorescence (visible light obtained by being converted by the phosphor layer) is used as an auxiliary.
