Description
Technical field
The present invention relates to electric source lighting field and illuminating equipment field, form generator of magnetic energy formation closed magnetic circuit by magnetic core with holes in the middle of being installed in dual U-shaped, ellipse, circle or the rectangle in the pyriform lamp body, resonant circuit by the connection generator of magnetic energy produces electromagnetism alternation formation electromagnetic induction, reaches luminous lighting order ground by fluorescent material in the mercury atom activation lamp body in the magnetic energy replacement filament electrode ionization lamp body of electromagnetic induction acquisition.Solved the technical barrier that the filament electrode energy consumption is big, light decay is big, the life-span is short has been arranged.It is big to have solved the electromagnetic radiation, the radio frequency interference that form in electromagnetic induction lamp, the electrodeless lamp folding magnetic circuit, and weak heat-dissipating, electromagnetic conversion efficient are low, the technical bottleneck of homogeneity of product poor reliability.Overthrown the traditional lighting principle that activates the luminescent substance in the lamp body with filament, electrode emitting electrons, innovation and creation " integrated closed magnetic circuit pyriform magnetic energy lamp " new light sources.
Background technology
Traditional electric light source all has filament and electrode, all has filament electrode as incandescent lamp, fluorescent lamp, electricity-saving lamp, high-pressure mercury lamp, iodine-tungsten lamp, LED, sodium vapor lamp, Metal halogen lamp etc.; They have a common characteristic, and the cavity at the luminous lamp body that seals is built-in with filament or electrode exactly.The design of filament or electrode has increased many uncertain service factors, has increased the package fabrication process difficulty of glass material metal material and the design difficulty and the manufacturing cost of control circuit.These traditional filaments, electrode make the increase in temperature of lamp, and luminous efficiency is hindered, and have aggravated the light decay of luminescent substance.This traditional filament or be seated in electrode in the lamp body has influenced the photoelectric conversion efficiency of lamp and the useful life of lamp, has limited the range of application of lamp and the development of electric light source.
About 10～the 15Lm/W of luminous efficiency of existing incandescent lamp, opto-electronic conversion is lower than 15%, and the lamp life-span is lower than 1500 hours, and meritorious power consumption was about 83% greater than 20% in 200 hours for light decay;
About 35～the 55Lm/W of the luminous efficiency of fluorescent lamp, electricity-saving lamp, high-pressure mercury lamp, photoelectric conversion efficiency is lower than 35%, the lamp life-span is lower than 3000～10000 hours, meritorious power consumption is 26%～35%, idle power consumption is 41%～46%, power factor is lower than 0.55, and stroboscopic, dazzle are unfavorable for environmental protection and energy saving and healthy greatly;
About 8000～15000 hours of the lamp life-span of LED, inductance type sodium vapor lamp, Metal halogen lamp, the about 60～95Lm/W of luminous efficiency, light decay 1000 hours is greater than 25%.Photoelectric conversion efficiency about about 38%, the low voltage starting difficulty, lamp power sharply rose when voltage was higher than specified input voltage, power consumption sharply increases, power factor is lower than 0.5, and meritorious power consumption is higher than 36%～43%, and idle power consumption is greater than 48%, exist serious stroboscopic and dazzle, be unfavorable for environmental protection and energy saving and healthy.
