1, 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, low power consumption
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, if adopted LEDs that are twice as efficient as fluorescent lamps replace half of Japan's incandescent and fluorescent lamps, saving up to 6 billion liters of crude oil per year. The same effect of a fluorescent lamp is more than 40 watts, while the power of each LED is only 8 watts. .
3, 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. LED lamps are small in size, light in weight, and encapsulated in epoxy resin, which can withstand high mechanical shock and Vibration, not easy to break, the average life expectancy is up to 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, strong security and reliability
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, environmentally friendly
LED is an all-solid-state illuminant, impact-resistant and non-breakable, waste-recyclable, non-polluting, reducing a large amount of harmful gases such as sulfur dioxide and nitride, and the generation of greenhouse gases such as carbon dioxide. It can improve the living environment of people. It can be called “green lighting source.” Production There are three kinds of white LED technology: one, using the three primary color principle and the currently available red, green and blue three kinds of ultra-high brightness LEDs according to the light intensity 1:2:0.38 mixed into white, two kinds, using super Highly InGan blue LED, the tube is always added with a little pomegranate-based phosphor, which can produce yellow-green light under blue light excitation, and this yellow-green light can synthesize white light with the exposed blue light. The light LED uses ultraviolet light-excited trichromatic phosphor or other phosphor to produce white light mixed with multiple colors.
Of course, energy saving is the most important reason for us to consider the use of LED light sources. Maybe LED light sources are more expensive than traditional light sources, but with one year of energy-saving recovery of light source investment, we can obtain several times of energy-saving net cover every year for 4-9 years. period.
