A photochemical catalysis air cleaning and sterilizing lamp belongs to domestic appliance for daily use, especially to an improved lamp. The utility model provides a photochemical catalysis air cleaning and sterilizing lamp that integrates the photochemical catalysis technology and lamp. The utility model consists of a lamp base and a lamp tube; wherein, an electric ballast integrates with a plasma high frequency generator; the lamp hood is provided with a filter screen; the lamp hood connects to the lamp base by means of a suspending shaft; the lower part of the lamp tube is provided with an electric motor to drive a fan. The utility model can clean and sterilize the indoor air in a circulating manner to get rid of foul smell, which is suitable for rooms decorated, hospitals, nursing homes, bathrooms, workshops and toilets.

Description

Photocatalysis air-cleaning sterilization light fixture

Technical field:

This utility model belongs to the improvement in daily living article field, particularly a kind of light fixture.

Background technology:

Progress along with human science and technology, the living standard of urban and rural population quality improves, all kinds of polluter are also in continuous expansion, for example: " dioxin ", vehicle exhaust or the like, especially all kinds of harmful gass that employed various finishing material is produced during the daily finishing of people are constantly volatilized, and human body is caused very major injury.It has been recognized that the importance of environmental protection and the harm that ecological deterioration brings, so photocatalysis technology just becomes the development focus of countries in the world, occurred various light-catalysed instruments and equipment simultaneously.Yet these equipment all are that cost is higher, need purchase separately when needs, have taken the useful space, and need parking space or the like shortcoming again after use.

Technology contents:

In order to solve above-mentioned shortcoming, this utility model provides a kind of photocatalysis air-cleaning sterilization light fixture that photocatalysis technology and light fixture are combined as a whole.

This utility model is made up of lamp socket, fluorescent tube etc., and electric ballast and plasma high frequency generator are combined into electric part, and drainage screen is installed on the lampshade, and lampshade is to be connected by suspension rod with lamp socket, in the fluorescent tube lower end fan driven by motor is installed.

The utility model has the advantages that:

1, compound external coatings such as low-power UV-B excitation nano rank titanium oxide, ferrum in the employing produce excited oxygen and OH base, overflow through the activated carbon dish, and room air is carried out the circularly purifying sterilization, eliminates abnormal flavour.Be applicable to new clothes repair the house between, hospital, sanatorium, bathing pool, dining room, workplace, toilet etc.

2, adopt high power electrodeless quasi-molecule UV light source to produce high energy particle (excited oxygen and OH yl), the air pollution (as hydrogen sulfide, carbon monoxide etc.) in bustling highway section, city is carried out the nonhazardous processing, air quality is further improved.External form can be made into advertising lamp box and is installed in bustling block, integrates environmental protection and medium, is the necessary facility of urban development.

Description of drawings:

Fig. 1 is this utility model structural representation;

Fig. 2 is this utility model circuit working schematic diagram.

The specific embodiment:

This utility model is made up of lamp socket 1, fluorescent tube 5 etc., electric ballast 3 is combined into electric part with the plasma high frequency generator, and drainage screen 7 is installed on the lampshade 6, and lampshade 6 can stop next to the shin shielding action of surplus UV, drainage screen 7 is a material with the activated carbon, the white steel mesh face of built-in blower fan.The fan 4 that motor 2 drives is installed in fluorescent tube 5 lower ends.Lampshade 6 is to be connected by suspension rod 8 with lamp socket 1, and between the outer of lampshade 6 and the lamp socket 1 space is arranged.And by regulating the rotating of fan, regulating wind is to advance from drainage screen 7, goes out from the outer of lampshade 6 and the space between the lamp socket 1, still goes out from drainage screen 7, advances from the outer of lampshade 6 and the space between the lamp socket 1.Fluorescent tube 5 adopting quartz glass tube walls, and internal layer adopts rare earth five primary colours fluorescent material to send out visible light to be used for illumination and nano-catalytic oxygen compound coating.

This utility model circuit theory and work process:

High power electronic ballast provides operating current, voltage for the UV light source generator, make it stimulate and to be coated on the outer field nano composite oxide coating of the quartzy tube wall of UV light source at the luminous UV (253.7nm) that launches simultaneously, contact the generation light-catalyzed reaction with air at external coating, inspire reducible attitude oxygen and OH base airborne toxic gas is decomposed eliminating, this coating possesses the effect that stops UV to overflow simultaneously.

Be high-frequency pump type PPFC circuit, diode VD ₁, VD ₂With the capacitor C in the high-frequency energy feedback control loop ₁, C ₂And high capacity filter capacitor C ₃Deng the passive harmonic filter circuit of composition.The positive half cycle of high frequency electric is by diode VD ₂To electrochemical capacitor C ₃Charging.Then pass through VD at the high frequency electric negative half period ₁Return.High-frequency pump type PPFC circuit VD reaches more than the 300V, about the high 30V of output voltage than single electrochemical capacitor filter circuit of common bridge rectifier.Effective minimizing of mains ripple coefficient can be reduced to below 1.7 meters lamp current crest ratio.This PPFC circuit input current triple-frequency harmonics is lower than 10%, THD≤10%, line power factor λ 〉=0.99.Can make lumen coefficient＞95% of UV light source generator, the UV width of cloth is penetrated coefficient＞80%.

Fan is the quiet fan of whirlpool formula, makes the contaminated air forced action type suck the active carbon filtration system, and toxic gas is adsorbed decomposition.And the high energy particle OH base and the excited oxygen that excite for negative oxygen ion and photocatalysis provide the circulation working environment.

Anion generator can tentatively decompose toxic gas, and absorption flue dust and decomposition-reduction make airborne oxonium ion be in relative balance state, and concentration is 1,500,000/cm ³Anion pure and fresh as making behind cleaned air passes such as the forest cun rain.

The EMI power-supply filter can reduce voltage significantly, electric current pollutes, and civil power and household electrical appliance is not caused interference.
