Abstract

The invention provides a radio-frequency electrodeless ultraviolet light source, which includes a high-frequency generator and a light source. The light source includes a glass bulb, a hollow tubular stem located in the middle of the glass bulb, and a spiral tightly wound on the outer wall of the tubular stem. Transmitting coil; the tubular core column is an inner cavity with two ends through, and one end of the transmitting coil is the coil lead-out line; the high-frequency generator is connected to the coil lead-out line through a coaxial cable; the inner wall of the glass bulb is equipped with a metal shielding grid layer, A phosphor layer is sprayed on the metal shielding grid layer; the high-frequency generator includes a metal casing, a socket, a planar transformer and power devices, and the inner wall of the metal casing is equipped with a wave-absorbing material; the glass bulb is filled with argon. It has the characteristics of high luminous efficiency, low heat generation, good heat dissipation, long life, EMC index in line with national testing standards, low development and production costs, etc. It is a high-power ultraviolet light source with excellent performance.

Description

technical field [0001] The invention relates to a stimulated emission light source, in particular to a radio frequency infinite ultraviolet light source. Background technique [0002] Among various stimulated emission light sources, the price of sodium lamp and metal halide lamp is only about one-third of that of high-frequency electrodeless lamp and one-sixth of that of low-frequency electrodeless lamp, while the luminous efficacy of sodium lamp and metal halide lamp has exceeded 120Lm / W, that is, the luminous efficiency of the straight tube fluorescent lamp can reach 105Lm / W. At present, the price of the electrodeless lamps on the market is high and the quality is low, and the situation is embarrassing. However, there are filament electrodes in other light sources except electrodeless lamps, and the service life is greatly limited. Therefore, the electrodeless lamp is an inevitable trend in the development of light sources in the future. [0003] The existing electrode...
