Description

Economize electric lighting device

Technical field

The utility model relates to a kind of lighting apparatus, refers to a kind of low power consumption power that has especially, province's electric lighting device that maintenance cost is low.

Background technology

Lighting device generally is used in the various now buildings and the vehicles.Existing common lighting device includes incandescent lamp, fluorescent lamp and electricity-saving lamp or the like.

Traditional incandescent lamp throws light in the high thermoluminescent mode of tungsten filament, its power consumption is big, be its shortcoming of using, so almost replaced by fluorescent lamp than power saving, the power consumption of fluorescent lamp is lower than incandescent lamp, under equal-wattage, the illuminance that fluorescent lamp provided is good than osram lamp and incandescent lamp, the principle of fluorescent lamp is to utilize to fill argon and a little mercury in a hollow fluorescent tube, the conducting electric current excites mercury atom in fluorescent tube, produce the fluorescent material that is coated with on the ultraviolet ray bump tube wall behind the mercury atom gas discharge and produce visible light, yet, though the power consumption of traditional fluorescent lamp is low than incandescent lamp, but it economizes electrically still not enough, and only approximately thousands of hours life-span, desirable not to the utmost, and have the problem of environmental protection such as mercury pollution after discarded.

Please refer to Fig. 3, present electricity-saving lamp 90 on the market, one stabilizer 92 mainly is set in a lamp socket 91, on lamp socket 91, be arranged to rare one fluorescent tube 93 that is connected with stabilizer 92, fluorescent tube 93 inner chambers are filled inferior argon and mercury, and coating one fluorescent material 931 on the inwall, lamp socket is provided with a circular-arc lampshade 94, so that see through even soft the shedding of light energy of lampshade 94, when illumination, utilize stabilizer 92 to activate fluorescent tubes 93, gas discharge by mercury causes ultraviolet ray to shine fluorescent material 931, and produce visible light thus, the about 17-32W of the power consumption of this kind electricity-saving lamp 90, than conventional incandescent than power saving, yet, its fluorescent tube 93 is same as the lighting theory of general fluorescent lamp in essence, on source efficiency, be still not satisfactory because the high relation of its power consumption, its stabilizer 92 volumes are very huge and heavy, added a tool lampshade 94 many, made the jumbo increase of electricity-saving lamp 90 costs, far above the fluorescent lamp of equal illumination effect.

Other lighting device has cold-cathode tube in addition, but its illumination mode is subject in the small cavity, for reaching the large tracts of land range of exposures, must increase the cold-cathode tube number, or with backlight module, have cost to increase problem equally, and briliancy is with a toll of 40%.

So the design people, improves its not enough and disappearance because present various lighting devices are economized electrical deficiency and the too high various shortcoming of cost, and then creates a kind of province electric lighting device.

Summary of the invention

The purpose of this utility model provides a kind of province electric lighting device, by directly exciting the fluorescent material that is coated with on the lampshade to produce light illumination ultraviolet ray, thus, can reach high efficiency light-emitting usefulness, and improves the lighting device life-span.

For reaching above-mentioned purpose, the utility model proposes a kind of province electric lighting device, include:

One base;

One power rectifier variable frequency inverter is arranged in the base, and this power rectifier variable frequency inverter is provided with an active circuit;

One ultraviolet generator is arranged on the base, and is electrically connected with this power rectifier variable frequency inverter;

One fluorescent material is arranged on outside the ultraviolet generator, and in order to the ultraviolet ray that ultraviolet generator produced is converted to visible light; And

One lampshade is with the light transmissive material manufacturing, and is arranged on the base, is formed with the inner chamber that holds ultraviolet generator in the lampshade, is coated with one deck fluorescent material on lampshade.

By above-mentioned technological means, ultraviolet generator with low power consumption produces ultraviolet ray, and the fluorescent material that excites on the lampshade to be coated with produces light illumination, by this, the ultraviolet generator of low power consumption has replaced the ultraviolet function of old fluorescent tube internal gas discharge generation, and the lampshade that is coated with fluorescent material has replaced the fluorescent tube of old fluorescent lamp, and the lampshade overall dimensions are unrestricted and can change arbitrarily, fluorescent material surface area on the lampshade on the more old fluorescent tube of the surface area of fluorescent material enlarges more, thereby a splendid illumination can be provided.

Aforesaid ultraviolet generator is a cold cathode UV lamp.

Aforesaid fluorescent material is to be coated on the inner surface of lampshade.

Aforesaid fluorescent material is to be coated on the outer surface of lampshade.

Aforesaid fluorescent material is to be coated on the ultraviolet generator.

Aforesaid power rectifier variable frequency inverter is provided with an active circuit.
