Characteristics of light.com/" target="_blank">LED lamp:

1. Energy saving: The energy consumption of white LED is only 1/10 of incandescent lamp and 1/4 of energy saving lamp.

2. Longevity: Lifetime can reach more than 100,000 hours. Lighting for ordinary families can be described as "once and for all".

3. It can work at high speed: if the energy-saving lamp is frequently turned on or off, the filament will turn black and quickly break down, so it is safer.

4. Solid-state packaging, which belongs to the type of cold light source. So it's good for transportation and installation. It can be installed in any miniature and enclosed equipment without fear of vibration.

5. The LED technology is progressing rapidly. Its luminous efficiency is making an amazing breakthrough, and its price is also decreasing. The era of a white LED entering the family is rapidly approaching.

6. Environmental protection, no harmful substances of mercury. The assembly parts of the LED bulb can be easily disassembled and assembled, and can be recovered by others without the need for manufacturer's recycling.

7. Light distribution technology makes LED point light source expand to surface light source, enlarge luminous surface, eliminate glare, sublimate visual effect and eliminate visual fatigue.

8. Integrated design of lens and lampshade. The lens has the functions of focusing and protecting, avoiding the repeated waste of light, and making the product more concise and beautiful.

9. High-power led planar cluster packaging and integrated design of radiator and lamp holder. It fully guarantees the heat dissipation requirement and service life of led, fundamentally meets the arbitrary design of the structure and shape of LED lamps, and has the distinct characteristics of LED lamps.

10. Significant energy saving. With ultra-high brightness and high power LED light source and high efficiency power supply, it can save more than 80% electricity than traditional incandescent lamp, and its brightness is 10 times of that of incandescent lamp at the same power.

11. The super-long life is more than 50,000 hours, which is more than 50 times of the traditional tungsten filament lamp. The high reliable advanced packaging technology - eutectic welding is adopted for LED, which fully guarantees the long life of LED.

12. No stroboscopic. Pure DC operation eliminates the visual fatigue caused by stroboscopic light source.

13. Green environmental protection. It does not contain lead, mercury and other polluting elements, and does not pollute the environment.

14. Shock resistance, strong lightning resistance, no ultraviolet (UV) and infrared (IR) radiation. No filament and glass shell, no traditional lamp tube fragmentation problem, no harm to human body, no radiation.

15. Working under low thermal voltage, safe and reliable. Surface temperature is less than 60 C (ambient temperature Ta = 25 C).

16. Wide voltage range, universal LED lamp. 85V-264VAC full voltage range constant current ensures that life and brightness are not affected by voltage fluctuation.

17. Adopting PWM constant current technology, it has high efficiency, low heat and high constant current precision.

18. Reduce line losses and make the power grid pollution-free. Power factor (> 0.9), harmonic distortion (< 20%) and EMI meet the global target, which reduces the power loss of power supply lines and avoids high frequency interference pollution to power grid.

19. General standard lamp head can directly replace existing halogen lamp, incandescent lamp and fluorescent lamp.

20. The luminous visual efficiency can be as high as 80 lm/w. The color temperature of various LED lamps is optional, the color rendering index is high and the color rendering performance is good.

Obviously, as long as the cost of LED lamp decreases with the development of LED technology. Energy-saving lamps and incandescent lamps will inevitably be replaced by LED lamps.

More and more attention has been paid to energy saving and environmental protection of lighting, and the use of LED lamps has been vigorously promoted.

Advantages and disadvantages

* If the heat dissipation is not good, the service life will be greatly shortened.

* Low-end LED lamps are still less energy-saving than energy-saving lamps (cold cathode tube, CCFL).

* The initial purchase cost is higher.

* Because of the strong directionality of LED light source, special optical characteristics of LED should be considered in lamp design.

Below for neon and LED lights related comparison, add the latest LED technology to compare, not before you see in the network that information.

1. Does the LED light source have a life of 100,000 hours?

According to the light attenuation rate of 7%, the actual time is only about 50,000 hours. According to the light attenuation of 3%, the actual application can reach 80,000 hours.

2. Does LED not heat?

Yes, heat dissipation is required.

3. Can LED replace incandescent lamp?

Luminous flux, light efficiency and color rendering are acceptable, but they are too expensive and will not decrease in recent years. But the cost of replacing incandescent lamps can be reduced by increasing the luminous flux of the product.

4. Can LED be simply used as a common light source?

No, power supply, optical LED lamp and heat conduction are needed.

5. Performance and advantages comparison of two light sources

The advantages of neon light have been covered by LED, but the price of LED light is too high.

6. Power Supply Comparison of Two Light Sources

The low voltage of LED is good, but the load current is too large. The input current of large particle 1W single LED lamp is 350mA.

7. Controlling Technology Comparison of Two Light Sources

LED is easy to implement, but neon lamp is mature.

8. Stability comparison of two light sources

LED is inconsistent, neon lamp is quite stable. A few manufacturers can achieve relative stability, such as using CREE and AOD chips to combine the advantages of their respective chips.

9. Price comparison of two light sources

LED is more expensive, but yellow and red are comparable. The main price is white LED.

10. Comparison of Outdoor Use of Two Light Sources

LED lights can be completely waterproof and dustproof.

11. Comparison of Two Light Source Markets

The annual output value of global lighting products is US$42 billion (US$15 billion in China). The proportion of LED light sources is less than 1%.
