Abstract: A new type of electrodeless straight fluorescent lamp belongs to the field of electric light source. The utility model comprises an electrodeless straight fluorescent tube and an electronic ballast, characterized in that the electrodeless straight fluorescent lamp adopts a high borosilicate glass tube, and the inner wall of the tube is deposited with a rare earth red, green and blue phosphor of 0.1 mm thick. Powder, the discharge gas filled in the tube is a specific ratio of Ne, Ar, Xe (mercury-free) or a mixture of Ne, Ar, Kr, Xe, and mercury. The ends of the straight tube are covered with a 0.1 mm thick aluminum metal cap of 5 mm length. A 0.5 mm thick anaerobic resin adhesive is applied to the bottom of the inner layer of the metal cap, and a sheathed metal shielded wire is respectively disposed on the outer side of the both ends. The electronic ballast uses an AC220V/DC12V input method with a bipolar output and a phase difference of 180° between the two poles. Electrodeless straight fluorescent lamps are used with electronic ballasts in groups of 1-40 parallel groups. The utility model has uniform illumination and a service life of up to 50,000 hours. The preferred mercury-free lamp tube solves the pollution problem of mercury in the fluorescent lamp from the source, and has important significance for environmental protection.
