The Difference Between Energy-saving Lamps&LED Bulbs

LED bulbs refer to the new light-emitting diode bulb, a solid-state semiconductor device capable of converting electrical energy into visible light directly. Energy-saving lamps, also known as energy-saving bulbs, electronic bulbs, compact fluorescent lamps, and integral fluorescent lamps, are lighting devices that combine fluorescent lamps and ballasts (ballasts) into a single unit. 

Light-emitting diodes are usually made of gallium arsenide, gallium phosphide, and other semiconductor materials, which will emit light when passing a positive current, the colour of the light depends on the material used and can emit red, yellow, green and infrared light. Light-emitting diodes are generally packaged in transparent plastic, with a long pin for the positive terminal and a short pin for the negative terminal. Some light-emitting diodes have three lead pins and can emit two colors of light according to the voltage of the pins.

The energy-saving lamp is actually a compact fluorescent lamp with its own ballast. When the energy-saving lamp is lit, it is first heated by the electronic ballast to the lamp filament, which starts to emit electrons (due to the coating of some electron powder on the filament), the electrons collide with the argon atoms filled in the lamp, the argon atoms obtain energy after the collision and hit the mercury atoms inside, the mercury atoms leap after absorbing the energy and produce ionization, which constitutes the plasma state in the lamp. Plasma state. Because it uses a high-efficiency electronic ballast, while there is no incandescent lamp like the current heat effect, the phosphor energy conversion efficiency is high, reaching more than 50 lumens per watt, so save electricity.
