To provide a three wavelength lamp with a negative ion generating function and an air cleaning function which does not generate ozone as air pollution substance.
Titanium oxide as a photocatalyst is coated on the outer surface of a negative ion generating part so as to impose an air cleaning function such as sterilizing function or deodorizing function on the central part of the upper part of a trunk, and a metal fiber (MF3) brush having many protrusions with pointed end part is formed on each outer surface so as to generate negative ion at its inside without generating ozone. Accordingly, the three wavelength lamp with above construction, having negative ion generating function and air cleaning function, prevents the generated negative ion from extinction caused by the electromagnetic wave generated from the lamp. The photocatalyst is coated on the outer surface of a negative ion generating part, the air cleaning function is generated by the light having three wavelength generated by the lamp without UV-lamp. The generation of the ozone as the air pollution substance is prevented by the metal fiber (MF3) brush.
