The LED Light source

- Jun 26, 2019-

The LED Light source (LED refers to the Light Emitting Diode) is the Emitting Diode Light source. This kind of light source has the advantages of small size, long life and high efficiency, and can be used continuously for up to 100,000 hours. In the future, LED light source will also become the mainstream in the lighting field.

The basic characteristics of

1. High luminous efficiency

LED after decades of technical improvement, its luminous efficiency has been greatly improved. The lighting efficiency of incandescent lamp and halogen tungsten lamp is 12-24 lumens per watt, fluorescent lamp is 50-70 lumens per watt, sodium lamp is 90-140 lumens per watt, most of the power consumption becomes heat loss. LED light efficiency after improvement will reach 50 ~ 200 lumens/watt, and its light monochromatic, narrow spectrum, no filtering can directly emit colored visible light. All countries in the world are stepping up to improve the LED light efficiency research, in the near future its luminous efficiency will have a greater improvement.

2. Low power consumption

LED single tube power 0.03 ~ 0.06 watts, dc drive, single tube drive voltage 1.5 ~ 3.5 v, current 15~18 ma, response speed is fast, can be operated at high frequency. Under the same lighting effect, the power consumption is one-tenth of that of incandescent bulbs and one-half of that of fluorescent lamps. Japan estimates that half of its incandescent and fluorescent lamps are replaced by leds, which are twice as efficient as fluorescent bulbs. Saving the equivalent of 6 billion litres of crude oil a year. Bridge guardrail lights for example, the same effect of a fluorescent lamp 40 watts, and the use of LED each power is only 8 watts, and can be colorful changes.

3. Long service life

Using the electron light field radiation luminescence, filament luminescence easy to burn, thermal deposition, light attenuation and other shortcomings. LED lamp is small in size, light in weight, epoxy resin package, can withstand high strength mechanical impact and vibration, not easy to break. The average life span is 100,000 hours. The service life of LED lamps can reach 5 ~ 10 years, which can greatly reduce the maintenance cost of lamps and avoid the pain of changing lamps frequently.

4. Strong safety and reliability

Low heat, no thermal radiation, cold light source, safe touch: precise control of light type and luminous Angle, soft light color, no glare; Contains no mercury, sodium and other substances that may be harmful to health. The built-in micro-processing system can control the luminous intensity, adjust the luminous mode and realize the combination of light and art.

5, conducive to environmental protection

LED is all solid luminous body, shock resistant, impact resistant, not easy to break, waste can be recycled, no pollution. Light source volume is small, can be combined at will, easy to develop into light, thin, short and small lighting products, also easy to install and maintain. Of course, energy saving is the main reason for us to consider using LED light source. Maybe LED light source is more expensive than traditional light source, but the investment of light source is recouped by one year's energy saving, so that the annual net income period of energy saving is several times of 4 ~ 9 years.

advantages:

Energy conservation and environmental protection;

Life is long;

Moisture proof and shock resistance;

Flexible dimension;

Environmental protection;

Many changes;

Advanced technology;

Other advantages;

Low heat, miniaturization, short response time, etc., all of these make LED light source has great advantages, creating favorable conditions for application in practical production and life.
