One. Advantages
Compared with fluorescent lamp, fluorescent lamp has LED 10 advantages:
High luminous efficiency: 1.
The luminous efficiency fluorescent light is about 55-80 lm/W (Philips company for the luminous efficiency fluorescent light T8 72lm/W), and LED the luminous efficiency in 100 lm/W above, the company XLampXP Cree lately G - has to 130 luminous efficiency, and later lumens/W will continuously improve. The difference between now has nearly doubled. But after three times more likely to achieve more.


High efficiency: 2 lamps and lanterns mainly refers to the efficiency of lamps and lanterns is effective, because the efficiency of fluorescent light, and 360 degrees in the direction of the light is no use. So the fluorescent usually adopt a white chimney, can put the reverse of reflected light, generally speaking, fluorescent lamps and lanterns efficiency is only about 70%. And LED fluorescent lamp is 120 luminescence, so all light is effective. Although sometimes also can feel 120 luminous Angle, but the most cases or enough. But this glowing terms can be adjusted according to the need of.
The Philips mentioned for the luminous efficiency fluorescent light T8 72lm/W, a total of fluorescent 36W 2592 lumens, but only 70 percent, and the number of the lumen is so effective 1814.4 lumens, and LED the luminous efficiency has more than 130lm/W, assume for 100lm/W, so long as can be reached 1,800 lumens 18W, as long as the power of fluorescent half can have the same brightness.
And LED the luminous efficiency in increasing.
3 power with high efficiency
Because all except incandescent lamps and lanterns is needed beyond the special power supply, power efficiency will affect the efficiency of lamps and lanterns.
The company 36WT8 by Philips under fluorescent light, for example. It's the rated output power, but due to 36W access inductance ballasts, measured input power came in at 4.24 W, also is the core inductance loss, low efficiency 6.4 W 85%, most domestic core inductance power, power factor 10W in more than 0.512. And LED the power efficiency usually 90%, a 20W 18W LED as the input power leds. Power factor can reach more than 0.9.
Compared with fluorescent lamp can save more than half of the roughly, i.e. the LED by a fluorescent lamp can replace a 36 watts of fluorescent lamp.
Not only such, LED fluorescent lamp and many other advantages:
4 long life: a carefully designed LED the life can reach fluorescent five thousand hours. But a fluorescent lamp life usually only 5,000 hours (some domestic fluorescent life only 300 hours). Both are nearly 10 times. The best long life fluorescent lamp also only 10,000 hours, both are also five times.
5 don't contain mercury, no pollution. We know, fluorescent contain mercury. 36mm fluorescent lamp contains 25-45mg mercury, 26mm (T8) contains 20mg mercury. But are using fluorescent fragile glass as shell, once broken glass, mercury will soon evaporated into the air, can make the surrounding air mercury concentrations reach 10-20 milligrams/cubic meters, more than 1,000-2,000 stipulated by the state. While mercury is a kind of very harmful to human body of toxic substances, mercury vapor da 0.04-3 mg will make people in 2-3 months, chronic poisoning twleve - 8.5 mg will induce acute mercury poisoning, if the quantity achieves 20 milligrams, will directly cause death. And 1mg mercury is enough to 5454.5 kilograms of water pollution, to reach the standard of drinking. And LED fluorescent lamp in does not contain any toxic substances, is a kind of completely green non-pollution illuminant.
6 colour temperature range, almost can provide any color, but also can provide red, green, blue and any color, lamplight.
7. Color, high index of incandescent lamp, fluorescent lamp to 95 index of 65-80, and LED fluorescent lamp can > 80.
8 no uv radiation.
9 the glass is broken, impact resistance, resistance and vibration.
The external isolation power LED lamp, fluorescent lamp at both ends, only not exposed to high 36V below the line of dc voltage, electric safety risk, completely is a security lamps and lanterns.


Ii. The price
At present, the LED fluorescent lamp only drawback is that the price is high.
But although the price is about LED fluorescent lamp, fluorescent light around ten times, if it relates to life, saving and pollution-free, still is economical. Because if life and 5,000 hours of fluorescent lamp, then life compared to 5 million hours of LED fluorescent lamp has been worth 10 times more expensive to buy, but in the meantime save electricity is entirely pure income. In Japan, because the fluorescent contain mercury, so the broken fluorescent lamp will pay and buy a new fluorescent lamp also money as toxic substances processing. Therefore, in Japan with long life (10,000 hours) of fluorescent lamp, money is your 10 times the LED fluorescent lamp.

In some 24 hours of continuous working site, such as underground parking, 24 hours of overtime production factory etc. Saving is also very important. As mentioned above, a root of T8 LED fluorescent about 20 watts can save electricity, year can save 20x365x24/1000 = 175.2 KWH. If each degree to $0.7, so one year, can save electricity 122.64 yuan, two years, can save the cost of the LED fluorescent lamp. After save electricity will become pure income.

So now abroad have a call EMC (Energy Management Contract Management attitude make). By a consortium is funded or bank. For an underground parking lot or stores, but free installation LED fluorescent lamp to collect all the owners of electricity saving, agreement may for 5 years. Just two years later, he can recycle all investment, the third year, all the electricity saving becomes is pure income. This is a very favorable investment projects. China also began to someone to do so. In accordance with the law, rather Haitz LED price every ten years will reduce ten times!
