What is the difference between led bulbs and energy-saving lamps?

The main difference between led bulbs and energy-saving lamps is that they are different in nature, principle, and feature. The details are as follows:

First,Different in nature

1. LED bulb

LED bulb refers to a new type of light-emitting diode bulb, which is a solid-state semiconductor device that can convert electrical energy into visible light. It can directly convert electricity into light.

2. Energy-saving lamps

Energy-saving lamps, also known as energy-saving bulbs, electronic bulbs, compact fluorescent lamps and integrated fluorescent lamps, refer to lighting equipment that combines fluorescent lamps and ballasts (ballasts) into a whole.

Two, the principle is different

1. LED bulb

Light-emitting diodes are usually made of semiconductor materials such as gallium arsenide and gallium phosphide. They emit light when passing a forward current. The color 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 the long pin being the positive electrode, and the short pin being the negative electrode. Some light-emitting diodes have three lead-out pins, which can emit two colors of light according to the pin voltage.

2. Energy-saving lamps

The energy-saving lamp is actually a compact fluorescent lamp with its own ballast. When the energy-saving lamp is ignited, the lamp filament is heated by the electronic ballast, and the filament starts to emit electrons (because some electronic powder is coated on the filament). The electrons collide with the argon atoms filled in the lamp tube. After the argon atoms collide, they obtain energy and then hit the mercury atoms inside. The mercury atoms undergo ionization after absorbing the energy, forming a plasma state in the lamp tube. Because it uses high-efficiency electronic ballasts, and there is no current heating effect like incandescent lamps, the energy conversion efficiency of phosphors is high, reaching more than 50 lumens per watt, so energy is saved.

Three, the characteristics are different

1. LED bulb

① Energy saving. Research data shows that because LED is a cold light source, semiconductor lighting itself does not pollute the environment. Compared with incandescent lamps and fluorescent lamps, the power saving efficiency can reach more than 90%. Under the same brightness, the power consumption is only 1/10 of that of ordinary incandescent lamps and 1/2 of that of fluorescent tubes.

②, health. LED lights are driven by DC, no stroboscopic; no infrared and ultraviolet components, no radiation pollution, high color rendering and strong luminous directionality, good dimming performance, no visual error when the color temperature changes; cold light source The heat is low and it is safe to touch; these are beyond the reach of incandescent and fluorescent lamps. It can not only provide a comfortable light space, but also meet people's physiological health needs. It is a healthy light source that protects eyesight and is environmentally friendly.

③. Artistic. The selection of the light source directly affects the artistic effect of the light, and the monochromaticity is good, and the color purity is high. The combination of red, green, and yellow LEDs enables greater flexibility in the selection of colors and grayscale (16.7 million colors).

2. Energy-saving lamps


①. Compact structure and small size.

② High luminous efficiency 60Lm/w, power saving over 80%, saving energy.

③Longer life, 6-10 times that of incandescent lamps.

④. It can reduce heat release and save electricity.


① The energy-saving lamp starts slowly.

② Energy-saving lamps have an open-line spectrum (discontinuous), so the usual energy-saving lamps are biased towards purple light, and things will be severely discolored when viewed under the energy-saving lamps. Blue will turn purple, red and yellow will look more vivid. Therefore, energy-saving lamps should not be used in color matching workplaces. The ballast used in energy-saving lamps generates a certain amount of electromagnetic radiation when it generates instantaneous high voltage. The electromagnetic radiation of energy-saving lamps also comes from the ionization reaction between electrons and mercury gas. At the same time, energy-saving lamps need to add rare-earth phosphors. Because rare-earth phosphors themselves are radioactive, energy-saving lamps also generate ionizing radiation (ie, radioactive nuclear radiation).
