The air purified energy-saving light bulbs are the new developed products which can not only use as energy-saving bulb but also can act as air purifier for generating a million anions per cubic centi-meter. Anion is regarded as the air. The medical experts think that anion can sterilize the pathogen, reduce infection of disease hasten metabolism and improve immunity. Air Purified Energy-Saving Light Bulb is a kind of air purifier with lighting, which combines the functions of lighting, energy saving and air purifying. It belongs to genuine green environment protection products and will be consequentially becoming perfect in 21st century. Air Purified Energy-Saving Light Bulb can be widely used in public places such as home, office, coffebar, marketplace, hotel, hospital as well as school. It can purify the indoor air environment effectively, increase the content of anion and ensure to give out a clean and healthy environment. Negative ion ---- Vitamin in the air :--- Ion is produced when electron collides with molecule in the air. Those with negative charge are called negative ions. They are everywhere in the nature. Thundering, photosynthesis of plants and waterfall all can bring a great amount of negative ions. That抯 why people feel refreshing in thundering weather, the forest or under the waterfall. Functions of negative ion (anion) :--- ** The negative ion can effectively activate the oxygen molecule in the air and prevent air-conditioner related disease. ** It can improve the function of the lung. When people inhale negative ion, their lung can absorb 20% more oxygen and blow off 15% more CO2. ** It can activate many kinds of enzyme and improve metabolism. ** It can improve people抯 immunity. ** It can make people energetic, raise efficiency and improve sleep quality. ** Small amount of ozone will be produced when the anion generator is working. Combined with negative ion, the lamp can sterilize all kinds of virus and germ. **It can clear the dust and smoke by neutralizing their positive electronic charge and making them fall. ** It can reduce television and computer抯 harm to people抯 eyes and keep TV and computer from dust. ** The hair itself has positive ions, which will absorb dusts to its surface. A great amount of static electron is produced when people do up the hair with comb, which makes the hair stand. The negative ion can neutralize the static electron and make hair fall smoothly. The operating principle of the anion generator :--- The anion generator can convert low voltage into negative high voltage by special circuit and release a great amount of electrons. These electrons are captured by oxygen in the air and the negative ion is produced. The principle is like that of thundering in the nature.
