The principle of barium tungsten cathode beauty lamp mainly combines the emission characteristics of barium tungsten cathode and the principle of specific spectral light therapy.
Firstly, a barium tungsten cathode is a thermal cathode composed of a porous tungsten sponge substrate and barium compounds filled within it. When heated, the barium tungsten cathode can emit electrons, which are then accelerated and focused under the action of an electric field, forming an electron beam.
In beauty lamps, the electron beam generated by the barium tungsten cathode is used to excite the gas inside gas discharge tubes (such as xenon lamps), thereby producing specific spectral light. These rays typically include light of different wavelengths such as ultraviolet, visible, and infrared.
Next, these specific spectra of light are used for therapeutic or cosmetic purposes. Different wavelengths of light have different effects on the skin. For example, certain wavelengths of light can stimulate collagen regeneration in the skin, promoting skin firmness and elasticity; Other wavelengths of light can destroy melanin in hair follicles, achieving hair removal effects.
In addition, the barium tungsten cathode beauty lamp can also be pulse modulated as needed to generate pulsed light (IPL) or intense pulsed light. Pulse light can more accurately control the energy and duration of light, thereby acting more precisely on skin tissue and achieving better therapeutic effects.
Overall, the barium tungsten cathode beauty lamp generates an electron beam through the barium tungsten cathode, which excites the gas inside the gas discharge tube to produce a specific spectrum of light, and uses this light for skin treatment and beauty. The principle is based on the different effects of different wavelengths of light on the skin, as well as pulse modulation technology to achieve more precise treatment.
