LED light VS incandescent light
LED is a new type of light source, which has significant advantages in comparison with traditional incandescent lamps.
1, LED light source has high luminous efficiency
Comparison of luminous efficiency: incandescent lamp, halogen tungsten light effect is
12-24 lumens / watt, fluorescent lamp 50-70 lumens / watt sodium lamp 90-140 lumens / watt,most of the power consumption becomes heat loss.
LED light effect: can be sent to 50-200 lumens / watt, and the illumination has good monochromaticity, narrow spectrum, no filtering, and can directly emit colored visible light.
2, LED light source consumes less power
LED single tube power 0.03-0.06 watts, using DC drive, single tube drive voltage 1.5-3.5 volts. The current of 15-18 mA reflects the speed and can be operated at high frequency.
In the case of the same lighting effect, the power consumption is one ten thousandth of the incandescent lamp, one-half of the fluorescent tube, Japan estimates, such as It replaces half of Japan's incandescent lamps and fluorescent lamps with LEDs that are twice as bright as fluorescent lamps, saving equivalent to 6 billion liters of crude oil per year. The same effect of a fluorescent lamp is more than 40 watts, and each LED is used. The power is only 8 watts.
3, LED light source has a long service life
Incandescent lamps, fluorescent lamps, and tungsten halogen lamps are characterized by electronic light field radiation, filament light-emitting, heat deposition, light attenuation, etc., and LED lamps are small in size, light in weight, epoxy resin package, and can withstand high-strength machinery.
Shock and vibration, not easy to break, the average life expectancy is 100,000 hours, LED lamp life can reach 5-10 years, can greatly reduce the maintenance cost of the lamp to avoid frequent lamp replacement.
4, LED light source is safe and reliable
Low calorific value, no heat radiation, cold light source, can be safely touched, can accurately control light type and illuminating angle, light color and no glare, no mercury, sodium and other substances that may be harmful to health.
5, LED light source is environmentally friendly
LED is an all-solid-state illuminant, is resistant to impact, is not broken, waste can be recycled, no pollution, and a large amount of harmful gases such as sulfur dioxide and nitrides, and greenhouse gases such as carbon dioxide, which improve the living environment of people, can be called "green lighting source."
There are three kinds of white LED technology in production: one, using the three primary color principle and the three kinds of ultra-high brightness LEDs of red, green and blue that can be produced at present, mixed in light ratio of 1:2:0.38 to form white, two kinds, using Ultra-high InGan blue LED, the tube is always added with a little punctured pomegranate as the main fluorescent powder, which can produce yellow-green light under blue light excitation, and this yellow-green light can be combined with the transmitted blue light to synthesize white light.
The ultraviolet LED is made of ultraviolet light-exciting trichromatic phosphor or other fluorescent powder to produce white light mixed with multiple colors.
Energy conservation is the most important reason for us to consider the use of LED light sources. Perhaps the current LED light source is much more expensive than the traditional light source, but the energy saved in one year can recover the investment when the light source was purchased. In the next 4-9 years, it can save several times every year, so in the long run Look, LED light source is still the best choice
