The special-purpose device, the external electrode type fluorescent device for light intensity suppresses the formation of the water-alloy and achieves high incidence [Prior Art] Excellent properties of μ ΪΪΪ ' such as high luminous intensity, high color rendering , 曰 display - power miscellaneous, etc., has been widely used in such as reading light source such as TV, computer, etc., the image source of the photocopier, and the image light source of the photocopying machine. In the cold cathode fluorescent lamp, the neon is applied to an electrode near the Wei of the light transmission tube made of ◎ glass ϊ, and the light transmission tube is mixed. The method saves the dilute body and mercury, so that the rare gas is swept by the photoelectron S, and only a very small amount of photoelectrons appear as a sub-electron in the light transmission tube, and the rare gas ions of the chemical force hit the electrode and emit two Sub-electricity W: This produces a grading electric power' and the mercury swell is excited by the post-myelin ultraviolet light. When the t-light is on the ultraviolet side, (4) the fluorescent material on the inner wall of the light-transmitting tube emits light. In such a cold cathode lamp, since the electrode is subjected to a rare gas=special scale, the electrode-type fluorescent lamp is placed, and the electrode is disposed on the peripheral surface of the light transmission to reduce the splashing. damage. /Cold cathode fluorescent lamp is placed in a space (dark area) that blocks external light from entering for a long time.
