1. High luminous efficiency
After decades of technological improvement, the luminous efficiency of LED has been greatly improved. The efficiency of incandescent lamp and halogen tungsten lamp is 12-24 lumens/watt, fluorescent lamp is 50-70 lumens/watt and sodium lamp is 90-140 lumens/watt. Most of the power consumption becomes heat loss. After improvement, the light efficiency of LED will reach 50-200 lumens/watt, and its light has good monochromaticity and narrow spectrum. It can directly emit colored visible light without filtering.
2. Low Power Consumption
The power of single LED transistor is 0.03-0.06 W. It is driven by DC. The driving voltage of single LED transistor is 1.5-3.5 volt. The current is 15-18 mA. The reaction speed is fast and it can be operated at high frequency. Under the same lighting effect, the power consumption is one-tenth of an incandescent bulb, one-half of a fluorescent tube, Japan estimates, such as replacing half of the Japanese incandescent lamp and fluorescent lamp with LED, which is twice as efficient as fluorescent lamp. It can save 6 billion litres of crude oil every year. For example, a fluorescent lamp with the same effect is more than 40 watts, while the power of each LED lamp is only 8 watts, and it can be varied in different colors.

3. Long service life
Under normal conditions, the light attenuation of LED can be reduced to 70% of the nominal life of 100,000 hours, which reduces the replacement frequency and other maintenance work. The service life of LED lamps can reach 5 to 10 years, which can greatly reduce the maintenance cost of lamps and avoid the trouble of changing lamps frequently.
4. Purity of light and color
LED can be used in a variety of combinations, especially in decoration. Bright saturation, pure, no need for filters, can be used red, green and blue tricolor elements into a variety of different colors, can achieve changeable, gradual change, mixing effect, color rendering effect is excellent. It can realize continuous adjustable brightness, high color purity, dynamic color transformation and digital control.
5. Safety and reliability
Low calorific value, no thermal radiation, cold light source, can be safe to touch: can accurately control the light type and luminous angle, light color is soft, no glare; does not contain mercury, sodium and other substances that may endanger health. The built-in micro-processing system can control the luminous intensity, adjust the luminous mode, and realize the combination of light and art.

6. Benefiting the Environment
LED is all solid-state light-emitting body, shock-resistant, impact-resistant and not easy to break, waste can be recycled, no pollution. The light source is small in size and can be assembled at will. It is easy to develop into light, thin and short small lighting products, and easy to install and maintain. Of course, energy saving is the main reason why we consider using LED light source. Perhaps LED light source is more expensive than traditional light source, but it takes one year to save energy to recover the investment of light source, so as to obtain a net income period of energy saving several times per year in 4 to 9 years.
7. Moisture-proof and anti-vibration
Because the exterior of LED is mostly protected by epoxy resin, the sealing performance and impact resistance of LED are very good, and it is not easy to damage. It can be applied to underwater lighting.
8. Flexible shape and size:
It can realize the organic integration with the building and achieve the effect of seeing light but not light.
9. Advanced Technology
Compared with the monotonous luminous effect of traditional light source, LED light source is a low-voltage microelectronic product. It successfully integrates computer technology, network communication technology, image processing technology, embedded control technology and so on, so it is also a digital information product, a semiconductor optoelectronic device "high-tech cutting-edge" technology, with online programming, unlimited upgrade, flexible and changeable characteristics.
10. Other advantages:
Low calorific value, miniaturization and short response time make LED light source have great advantages and create favorable conditions for practical production and life.
