The reflective coating layer that the described second tubular cell-shell outer wall described in the utility model has is metal reflective coatings such as aluminium coated or silver coating, the light that can effectively fluorescent coating be sent reflexes to the one side that needs illumination in the shortest distance, reduced the light reflex time and increased the optical loss that produces, made whole fluorescent lamp more energy-saving and cost-reducing with distance.The screen that the second tubular inner wall described in the utility model has also is existing commercially available prod, and effectively shield electromagnetic interference guarantees that fluorescent lamp also reduces electromagnetic radiation greatly in the optimum state operate as normal.

Say that from technical standpoint the utility model has been done labor to the essential condition of fluorescent lamp after the existing technical problem of fluorescent lamp of two types of analyses, by a large amount of experiment contrasts.Release and have effective area, the control light loss of fluorescent lamp now, improve efficiency, control electromagnetic radiation and aspect such as increase the service life, more superior no filament ion fluorescence lamp at this at bulb structure, luminous element form, active mode, increase luminous element.The utility model is in view of there being the existing problem of the electrodeless lamp prior art of a fluorescent lamp and electromagnetism to put forward, and promptly increases effective luminous quantity and propose at the energy loss that do not increase that existing non-filament florescent lamp is not had.Its purpose is to provide a kind of efficient, energy-saving and environmental protection, long-life, have more decorative effect convenient substituting existing incandescent lamp bulb, wide accommodation, be convenient to large-scale industrial production and be fit to the fluorescent lamp of most of places illumination.Shell described in the utility model can be the water proof lamp shell.

No filament ion fluorescence lamp operation principle of the present utility model is as follows:

Is direct current 300V through the drive circuit device with the 220V AC rectification, again through vibration, excitation, power amplification converts medium-frequency pulse to and exchanges about 2800V, through first electrode output of drive circuit device and second electrode output medium-frequency pulse electric current is added to ring-type first emission electrode (the A utmost point) that the dielectric cavity inwall fixedly installs and second emission electrode (the B utmost point) of dielectric cavity inwall respectively again, thereby the ion chamber that is commonly referred on the formation electricity, be subjected to electric field action, electronics high-speed impact in ion chamber produces heat energy (warm), dielectric gas in the dielectric cavity is ionized and transfers plasma to simultaneously, excite generation luminous energy and fluorescent material is subjected to ion bombardment, transfer the luminous energy process to thereby finished electric energy.

The utility model control light loss principle: various lamps such as the existing straight lamp of contrast, U type lamp, spiral spot, non-filament florescent lamp or the electrodeless lamp of electromagnetism all adopt indirect reflective form, promptly with the reflective loss of controlling effective light of lampshade.Because lampshade is located in the air for a long time, the very easily oxidized and dustiness of electrostatic interaction lampshade has just lost or has partly lost the function that reflects light simultaneously in addition.No filament ion fluorescence lamp of the present utility model has been owing to adopted the luminous form of single face, and the reflective coating layer is located at foam inside, makes the luminous energy of foam inside fully be reflected utilization.Because of the reflective coating layer is in vacuum state, the reflective coating layer can oxidized and dustiness, reaches control to light loss with this.

The effective light of the utility model utilizes principle: because of technical reason, the structure of existing fluorescent lamp or non-filament florescent lamp is the distortion of straight tube-like or straight tube, and is as U-shaped, spirality or with the multitube combining structure, quite serious to the loss of effective light.Except reflective loss, light is offset between fluorescent tube and the fluorescent tube besides.For example the cylinder lamp and the bank lights of the combination of many U-shaped pipes, to the loss of effective light up to 20-35%.And luminous and pure the luminescence technology of vertical plane 360 degree of horizontal plane 180 degree adopted in no filament ion fluorescence of the present utility model, do not have stealthy light-emitting area, overcome the light loss that the multitube combination causes, and improved making full use of effective light.

The utility model Acceptable life principle: from the Acceptable life of fluorescent lamp, General Definition is exactly when filament in case damage, and just means the termination in useful life.Quicken the key factor that fluorescent tube damages and be in the hot operation district for a long time.As the ablation to fluorescent coating, shorten the useful life that the unbalance grade that pipe is pressed all can be directed at lamp.No filament ion fluorescence lamp cancellation filament pre-heating active mode adopts electronics to quicken preheating technology, and anti-lonely cover can be set, and makes fluorescent coating obtain effective protection.And each parts of lamp all are in the warm scope of safety for a long time, therefore, the life-span of no filament ion fluorescence be silk arranged 6-10 doubly, the 3-5 of electromagnetism lamp times.The radiation proof principle: compare with the high-frequency electromagnetic electrodeless florescent lamp, no filament ion fluorescence lamp of the present utility model is not established flux path because of adopting inner chamber direct ionization technology, so there is not leakage field full-shield setting in addition, has good radiation proof and anti-tampering performance.

The maximized light-emitting area principle of the utility model: people adopt multitube to make up the illumination that increases lamp, and the many more just wastes of combination are big more and power consumption is many more in order to increase the lighting power of lamp.No filament ion fluorescence lamp of the present utility model need not make up, and single lamp light-emitting area maximum can be accomplished a square meter level, and single lamp power can be accomplished multikilowatt, can fully satisfy various different lighting demands.

The utility model energy-conservation with the resource principle: since no filament ion fluorescence lamp of the present utility model to have used inner chamber vacuum light reflective, technology such as dual activation, low power consuming medium are applied to not have filament ion fluorescence lamp, have improved Energy Efficiency Ratio.

Compared with the aforementioned existing similar products, no filament ion fluorescence lamp efficiency height of the present utility model, energy savings, environmental protection is radiationless, longer service life, have more decorative effect convenient substituting existing incandescent lamp bulb, wide accommodation, be convenient to large-scale industrial production and be fit to the illumination of most of places.
