what are main advantages of LED lamps

1. High luminous efficiency

After decades of technological improvement, LEDs have greatly improved their luminous efficiency. Incandescent lamps and tungsten halogen lamps have an effect of 12-24 lumens/watt, fluorescent lamps 50-70 lumens/watt, and sodium lamps 90-140 lumens/watt. Most of the power consumption becomes heat loss. The improved LED light efficiency will reach 50-200 lumens/watt, and its light has good monochromaticity and narrow spectrum, and can directly emit colored visible light without filtering.

2. Low power consumption

LED single-tube power is 0.03-0.06 watts. It is driven by DC. The single-tube driving voltage is 1.5-3.5 volts, and the current is 15-18 mA. The response speed is fast, and it can be operated at high frequency. Under the same lighting effect, the power consumption is 1/10,000 that of incandescent bulbs, and 1/2 that of fluorescent tubes. Japan estimates that if LEDs with twice the light efficiency are used to replace half of incandescent bulbs and fluorescent bulbs in Japan. fluorescent lamps. The equivalent of 6 billion liters of crude oil can be saved every year. In the case of bridge guardrail lights, a fluorescent lamp with the same effect is more than 40 watts, while the power of each LED is only 8 watts, and it can be colorful.

3. Long service life

Under normal circumstances, the use of LED, its light decay can be reduced to 70% of the nominal life is 100,000 hours, reducing the frequency of replacement 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 pain of changing lamps frequently.

4. Pure light color

LEDs can be freely combined with a variety of combinations, especially suitable for decoration and other aspects. Bright, saturated, pure, no filter is needed, red, green, and blue elements can be used to adjust to various colors, which can achieve variable, gradual, and mixed light effects, and the color rendering effect is excellent. The brightness can be continuously adjusted, the color purity is high, and the color dynamic transformation and digital control can be realized.

5. Strong safety and reliability

Low calorific value, no thermal radiation, cold light source, can be safely touched: can accurately control the light type and luminous angle, soft light color, no glare; 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.

6. Conducive to environmental protection

The LED is a solid-state light-emitting body, which is shock-resistant, impact-resistant and not easily broken. The waste can be recycled without pollution. The light source is small in size and can be combined at will. It is easy to develop into a light, thin, short and small lighting product, and it is also easy to install and maintain. Of course, energy saving is the main reason for us to consider using LED light sources. Maybe LED light sources are more expensive than traditional light sources, but the investment in light sources can be recovered with one year of energy saving, thereby obtaining several times the net energy saving period of each year in 4 to 9 years. .

7. Moisture-proof and anti-vibration

Since the exterior of the LED is mostly protected by epoxy resin, the sealing performance and impact resistance are very good, and it is not easy to be damaged. It can be applied to underwater lighting.

8. Flexible dimensions:

It can realize the organic integration with the building, and achieve the effect of only seeing the light but not the light.

9. Advanced technology

Compared with the monotonous luminous effect of traditional light sources, LED light sources are low-voltage microelectronic products. It successfully integrates computer technology, network communication technology, image processing technology, embedded control technology, etc., so it is also a digital information product, a "high-tech" technology for semiconductor optoelectronic devices, with online programming, unlimited upgrades, flexible and changeable. Features.

10. Other advantages:

Low heat, miniaturization, short response time, etc., all make LED light sources have great advantages, creating favorable conditions for application in actual production and life.
