LED lighting outstanding advantages and disadvantages

The outstanding advantages of LED lamps are:

1, energy saving, LED's luminous efficiency is high, the general incandescent lighting effect is 15-20LM / W, LED lamps with high luminous efficiency can reach 60-100LM / W; that is, the traditional 60W incandescent lamp with 10W or so LED lamps can be replaced; LED lamps also save about 20% more than fluorescent lamps.

2, environmental protection, LED is a semiconductor device, does not contain mercury and other heavy metal element materials; traditional energy-saving lamps in the manufacturing process and after the use of mercury pollution, energy-saving lamps LED lighting manufacturing process and during use will not produce mercury pollution.

3, long life, LED theoretical life of 100,000 hours, the current quality of good LED lamps warranty life of 25,000 hours, incandescent lamp life is only 1000 hours, the life of fluorescent lamps is more than 7000 hours.

4, high color rendering index, which is the high degree of color reproduction.

5, LED is a DC drive, more suitable for solar lamps, solar panels life of 10-15 years, plus the LED's long life will be a lot of maintenance costs will decrease the overall lamp; to avoid frequent replacement of light source maintenance costs.

The disadvantages of LED lamps

1. The cost is relatively high. At present, LED lighting fixtures gradually enter the field of commercial lighting, and it will take time for LED lamps to be used in large-scale applications in the general lighting field because of manufacturing costs.

2. The LED needs constant current driving power. The service life of the power supply also affects the service life of the whole lamp. If the LED power supply is installed and replaced more conveniently, the impact of the power supply on the life of the entire lamp can be overcome.
