What are the advantages of LED?
Energy saving:
LED power consumption is very low, generally the operating voltage of the LED is 2-3.6V. The operating current is 0.02-0.03A. This means that it consumes no more than 0.1W. LED luminous efficiency is high. The mainstream white LED launched in 2007 has a lumen value of about 60-90. This efficiency is extremely significant for incandescent lamps with luminous efficiencies of only 14-17.5 lm/w and halogen lamps with efficiencies of 16-21 lm/w.
Luminous efficiency is an important indicator of energy savings, but not all, especially for directional light sources. Due to the natural nature of directivity, LEDs are more energy efficient than other sources in lighting applications. Fluorescent lamps and bulb-shaped incandescent lamps are illuminated in all directions, and most of the light is lost in the luminaire and reabsorbed by the lamp; or from the luminaire to the non-target application area. Many fixtures, including embedded downlights, grille panels and brackets, are not uncommon for light loss of 40-50%. Because LEDs are direct light and do not require reflectors and diffusers, well-designed LED fixtures and systems can deliver light more efficiently to the target area.
long life:
The illuminating mechanism of incandescent lamps is that electric energy heats and emits luminescent tungsten wires. After a long period of heating, the tungsten wires will age or even burn out. At this point, the life of incandescent bulbs ends, and the luminescence mechanism of LEDs ends. It is determined by the special composition of the diode. The diode is mainly composed of a PN junction chip, an electrode and an optical system. When a forward bias is applied to the electrode, electrons and holes are injected into the P region and the N region, respectively. When the balance of minority carriers and majority carriers is balanced, excess energy is converted into light energy in the form of radiated photons. The illuminating process consists of three parts: carrier injection under forward bias, composite radiation, and light energy transmission. It can be seen that the diode is mainly illuminated by the continuous movement of carriers, and there is no aging and burning phenomenon. Its special illumination mechanism determines its luminous lifetime of up to 50,000-100,000 hours.
Environmental protection:
LEDs are made of non-toxic materials. It emits very little heat, does not waste too much heat like incandescent light, does not produce toxic gases like high-energy energy like fluorescent lamps, and does not require high voltage and is easily damaged like neon lights. It has been recognized as a generation of high environmental protection. Technology Products.
strong and sturdy:
The LED is completely encapsulated in epoxy, which is stronger than both the bulb and the fluorescent tube. There are no loose parts in the lamp body. These features make the LEDs hard to damage.
Small size / wide range of applications:
The LED is basically a small chip that is encapsulated in epoxy, so it is very small and very light. Can be used in architectural landscape appearance illuminators; elevated, high-rise, highway, bridge, landmark, landmark building light source; advertising three-dimensional characters, signs, indicating light source; commercial space, airport, construction, subway, hospital, hotel, shopping mall, plaza, PUB design lighting; automotive, transportation, ship, propaganda instructions warning light source; computer, mobile phone, communication, signal transmission and other application light sources.
