Energy saving characteristics of LED lights

- Jun 19, 2019-

1. LED light source has high luminous efficiency

Comparison of luminous efficiency: incandescent lighting effect is 10-15lm, halogen tungsten light effect is 12-24 lumens/ watt, fluorescent lamp 50-90 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 18 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. The 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 3-5 million hours, LED lamp life can reach 3-5 years, can greatly reduce the maintenance cost of lamps to avoid frequent lamp replacement.

4. Strong safety and reliability

Low calorific value, no heat radiation, cold light source, safe to resist, 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

The LED is an all-solid-state illuminant, is resistant to impact and is not easily broken, waste can be recycled, no pollution, and a large amount of harmful gases such as sulfur dioxide and nitride, and greenhouse gases such as carbon dioxide are generated to improve the living environment of people, and can be called "green illumination source".

6. LED light source is more energy efficient

Of course, energy saving is the most important reason for us to consider the use of LED. Maybe LED is more expensive than traditional light source, but it takes one year's energy saving to recover the investment of light source, thus obtaining several times of energy saving net closing period in 4-9 years.
