Energy-saving lamp is a popular version, also known as saving lamps, electronic bulbs. Strictly speaking, the energy-saving lamp refers to the rare earth Tri-phosphor compact fluorescent lamps, and ballasts for fluorescent lamps (stabilizer) into an overall lighting. Originally, this compact fluorescent light bulbs simply consuming incandescent power of 1/5 to 1/4, you can achieve the same light output as incandescent and compact fluorescent lighting can save a lot of electricity and costs, therefore known as "energy-saving lamps".

Fluorescent lamps, also known as fluorescent lamps. Thin, long. Fluorescent lamp at each end there is a filament lamp tube has a thin trace amounts of argon and mercury vapor, on the inner wall of the tube is coated with a fluorescent powder, conductive filament between two gases when UV rays, makes the phosphor gives a soft light.

Traditional fluorescent lamps and electrodeless fluorescent lamps fluorescent lamps, traditional fluorescent low pressure mercury lamps are used in low pressure mercury vapor discharge ultraviolet radiation, so that the principle of light phosphor emits visible light, so it belongs to the low pressure arc discharge.
