Embodiment Construction
[0031] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings. Such as figure 2 , image 3 shown. The invention is a radio frequency electrodeless ultraviolet light source. It includes high frequency generator 1 and bulb 2. The light bulb 2 includes a glass bulb 3 , a tubular stem 4 located in the middle of the glass bulb 3 , and a transmitting coil 5 spirally wound on the outer wall of the tubular stem 4 . Inside the tubular stem 4 is an inner cavity through which both ends pass through. The transmitting coil 5 is wound by an ultra-high temperature enameled wire with a diameter of 0.7 mm, and its two ends are coil lead wires 6 , and the high frequency generator 1 is connected to the coil lead wire 6 through a coaxial cable 7 . The inner wall of the glass bulb 3 is provided with a metal shielding grid layer 8, which is a #-shaped metal sash with a thickness of 10 μm, a frame body of 1 mm, and a frame ...
