No pole lamp overcome the key technology of optical attenuation of the lamp, electrodeless lamp lights are prone to degradation of several main reasons for, except by perfect crystals, crystal integrity, clear and smooth surface, no miscellaneous phase, particle size uniform ball milling free rare-earth fluorescent powder, the following work art technology, decrease the lamp lumen:

    1, the new formulation of the nano technology: for rare earth trichromatic fluorescent powder using nonionic polymer - poly (ethylene oxide) as nano technology of temporary binder. The binder decomposition temperature is low, at 2000c begins to decompose, and reach the decomposition temperature, it from the polymer decomposed into monomers, and these monomers to gaseous run away. Therefore, the poly (ethylene oxide as a temporary binder can guarantee has been shaped glass tube in tube baking stage bond all the baked as, and the glass tube is not deformed. This prevents the fluorescent powder layer on the black ceiling light film formation.

    2, the protective film technology: in order to prevent sodium ions in the glass tube of the blackening and glass heat dissipation to the fluorescent powder layer, for executives wall load no pole lamp (tube diameter 10mm, currents greater than 0.2A), adopts the technology of protective film, namely before powdering, first coated with a layer of protective film. There are two kinds of protective film, one is a transparent oxide protective film; the other is a transparent protective film. Production practice has proved that the two protective films have protective effect. Adopts the technology of protective film, glass tube no longer because of mercury infiltration and melanization, fluorescent powder is no longer due to the sodium amalgam in the generation of the surface and coloring, lamp 2000h and 5000h lumen maintenance rate are greatly enhanced.

    After 3, drying tube, cathode coatings and exhaust process optimization: using poly (ethylene oxide) as binder, powder tube tube baking process specification should according to the characteristics on thermal degradation of poly (ethylene oxide to formulate, in order to get the best without binder powder layer. The exhaust gas should be matched with the pumping rate of the vacuum system in order to be beneficial to the formation of the intermediate layer of the barium. Exhaust baking temperature is higher, the time to fully, the purity of the inert gas, so as to ensure that the lamp of impurity gas in pressure minimum, access to good attenuation characteristics.
