Description

The high-frequency pole-free Projecting Lamp

One, technical field

The utility model relates to a kind of electric source lighting lamp, specifically a kind of high-frequency pole-free Projecting Lamp.

Two, background technology

Current; Illuminating light fixture has multiplely on the middle and high lamp stand in the urban district, and incandescent lamp, the halogen tungsten lamp of heat radiation light source class, the fluorescent lamp of gas discharge class, high-pressure sodium lamp, high-pressure mercury lamp etc. are arranged; Every kind of lamp all has its distinct advantages and defective separately, all uses filament or electrode.The advantage that incandescent lamp and halogen tungsten lamp have high-color rendering, high power factor, start immediately, but light efficiency is low, service life short; The light efficiency height of gas discharge class, life-span prolong relatively, but can not start immediately, have also used expendable mercurial, are unfavorable for environmental protection.

Three, summary of the invention

In order to solve the deficiency of prior art, the purpose of the utility model provide a kind of high light efficiency, high-color rendering, life-span long, do not have the frequency of sudden strain of a muscle, energy-saving and environmental protection, promptly open high-frequency pole-free Projecting Lamp promptly bright, elegant in appearance.

The technical scheme that realizes the purpose employing of the utility model is: this high-frequency pole-free Projecting Lamp mainly is made up of electric appliance box, lamp body, lampshade, electromagnetic coupler, foam seat and fluorescence glass bulb; The high frequency generator of magnetic energy is housed in the electric appliance box, and electric appliance box is equipped with connection box that is connected with lamp stand and the connecting plate that is connected with lamp body outward; The aluminum lamp socket is housed in the lamp body, and there is lampshade the outer end, studs with reflection shield in the lampshade, and the end of lampshade is fixed with transparent weather shield, on the lamp socket in the lamp body electromagnetic coupler is housed, and fluorescence glass bulb and foam seat are fixed together and are screwed on the lamp socket; Electromagnetic coupler places in the reentrant cylindrical cavity of fluorescence glass bulb, and electromagnetic coupler is made up of passive heat-conducting metal rod, insulating sleeve, magnetic induction coil; Be fixed with insulating sleeve on the metal bar, be wound with magnetic induction coil on the sleeve, its magnetic induction coil is connected with the high frequency generator of magnetic energy through lead; Described fluorescence glass bulb seals the discharge cavity that an inwall scribbles three primary colors fluorescent powder with air tight manner, is filled with mercurial low pressure mist in the discharge cavity, and main mercurial and auxiliary mercurial are housed; The high frequency generator of magnetic energy that joins with power supply passes through to export a stable voltage signal after its inner processing of circuit; This signal is transferred to electromagnetic coupler through lead; Lean on magnetic induction coil to be coupled in the glass bulb, make the gas avalanche ionization in the glass bulb form plasma, when the plasma excited atom is returned ground state with induction mode; Spontaneous radiation goes out ultraviolet light, and the fluorescent material of glass bulb inwall receives uv light induction and sends visible light.

The advantage that the utility model is compared with prior art had is: electrodeless in the glass bulb, no filament, long service life, high light efficiency; High energy-conservation, high-color rendering, high reliability; Promptly open promptly bright, anti-vibration, few maintenance, light is extremely stablized flicker free; High bright free from glare, photochromic comfortable, soft, environmental protection.Be applicable to that fully being installed in the urban district middle and high lamp stand is used for illumination.
