Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to flat lamps, and in particular, to the application of free vacuum, free of filling gas, and free of high-temperature sealed flat lamps. And free of flat lights. [Prior Art] As shown in FIG. 1, the previous cold cathode fluorescent flat lamp 10 was dense, and the gas in the y cavity was discharged through an exhaust pipe 15, and inert gas or mercury vapor 11 was injected. Next, a high voltage is applied to the electrodes 12, 12 to cause electron migration between the electrodes. During the process of electron migration, the electrons 6 collide with the gas molecules, excite the inert gas or mercury vapor 1 in the sealed chamber, and radiate ultraviolet · light 13. Thereby, the ultraviolet light 13 excites the coated phosphor layer 17 coated on the inside of the tube wall of the cold cathode fluorescent flat lamp 10, and emits a visible light source 14. Among them, in addition to the complicated procedure of vacuuming, in the process of coating the fluorescent powder on the inside of the tube wall of the cold cathode fluorescent flat lamp 10, the high temperature range of 400 ° C to 800 ° C must first be applied. The evaporation of the organic solvent in the phosphor layer causes the phosphor to be adsorbed on the inside of the tube wall. If the evaporation of the organic solvent is incomplete, after a long period of irradiation, a scorch will occur at the electrode of the lamp. In addition, when the three-color phosphors such as red, green, and blue are unevenly distributed, the color temperature of visible light may deviate. Therefore, how to avoid complicated manufacturing processes and manufacture visible light sources with excellent temperature uniformity and high brightness is a problem that needs to be solved in the industry. [Summary of the invention] The main object of the present invention is to provide an inertia filling without vacuuming.
