Brief description of the advantages of LED light source

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, 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, 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. 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, 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, impact-resistant and non-breakable, waste-recyclable, non-polluting, reducing the generation of harmful gases such as sulfur dioxide and nitride, and the generation of greenhouse gases such as carbon dioxide. It 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 with a small amount of pomegranate-based phosphor added to the tube, which can produce yellow-green light under blue light excitation, and this yellow-green light can be combined with blue light to form white light. Ultraviolet LEDs use ultraviolet light-activated trichromatic phosphors or other phosphors to produce a multi-color mixture of white light.

6. 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 we can recover the investment of light sources with energy saving for one year, thus obtaining several times of energy saving every year for 4-9 years.
