Question:

LED to shoot the light is good

Friends have told me that the Hong Kong star can lighting production of LED lamp, LED bulb light. LED daylight tube is very save electricity, I find for a long time to find, now share with you what? Who can tell me what is he power-saving principle?

Answer:

Save electricity, and so you explain: for example, if you use 400 w street light before now open for eight hours a day, a month's worth of electricity is: 30 = 96 * 400 * 8 * 1 1 yuan (electricity) = 96 pieces and LED120W lamps can reach 400 w the same brightness, a month's worth of electricity is: 28.8 degrees 30 = 120 * 8 * * 1 1 yuan (electricity) = 28.8-28.8 = 67.2 96 blocks of a lamp can you make a month to save 67.2 piece of this is to save electricity! More than just... probably not very accurate
The lamp is incandescent lamp, principle of the first generation is heating filament under inert gas protection. Filament to a certain temperature when the potential energy of the electrons of the atoms of the outer is elevated to the unstable state, outer electrons when atoms never returned to steady state stability of high energy status will emit light. The working principle of this makes the most of the electrical energy into heat energy, can light energy is less than a few percent, efficiency is very low. The second generation of the electric light is a gas discharge lamp, including fluorescent lamp, fluorescent tubes, energy-saving lamps. Most of these lamps using high voltage ion release ultraviolet phosphors into visible light. So you need not too much heat loss, greatly increase the use of electric power, its luminous efficiency can reach twenty percent. The third generation of the light is LED (light emitting diode) lights, main points, high power and small power and different colors. The LED is the only principle of solid state light emitting light. Using cavity semiconductor PN junction and electronic to move atoms bond change rates can be released in the form of light. Because of the different semiconductor materials can be directly send red, yellow, green, blue and ultraviolet light. Blue light and ultraviolet light and fluorescent powder into white light. Do not need temperature and high pressure due to the working principle of the LED, so in theory to waste the least amount of electricity. Practice on the white LED is also continuing to improve photosynthetic efficiency. At present the highest photosynthetic efficiency can reach above thirty percent.
Leds into visible spectrum efficiency is high, with the same voltage, electric current produced by the visible light, electric touch less radiation and heat, power saving a lot of the same brightness LED.
The LED is solid cold light source the light shine. Using cavity semiconductor PN junction and electronic to move atoms bond change rates can be released in the form of light. Because of the different semiconductor materials can be directly send red, yellow, green, blue and ultraviolet light. Blue light and ultraviolet light and fluorescent powder into white light. Due to the LED work does not need to is thermal energy and power in a large number of photoelectric conversion rate is as high as 98%, so she is.
Don't watch brand! What to see whether the use of chip, chip technology in abroad several factory hands, such as the United States kerui, Taiwan wafer and on electricity, Germany's lang. LED light source is a big trend, no stroboscopic high advantage is energy-saving life! Ordinary incandescent lamp with 80% energy into heat energy, LED light-emitting diode technology with 90% of the electric energy into light energy, energy saving, of course!
