LED fluorescent lamp 10 merits

Is relative to the fluorescent , LED fluorescent light with 10 advantages:

1 . High efficiency :

Fluorescent light-emitting efficiency is about 55-80 lm / W (Philips company T8 fluorescent light-emitting efficiency of 72lm / W), while the LED luminous efficiency of 100 lm / W or more , the recent Cree 's XLampXP-G in the luminescent efficiency has to 130 lumens / W, and rise. Difference between the two has now almost doubled . The future may reach more than 3 times .

2 . Lighting efficiency :

The efficiency of lighting is efficient light efficiency, because fluorescent light is 360 degrees , and in the opposite direction of light on the issue of no use . Therefore, usually a white fluorescent lamp , can be a considerable portion of the reverse light reflected back , in general ,Fluorescent lamps are only about 70% efficiency。The LED fluorescent light is 120 degrees , so all light is an effective light .Although sometimes feel light-emitting angle of 120 degrees a bit narrower , but still enough for most cases . Moreover, this perspective is also light can be adjusted as needed .Mentioned earlier, the T8 fluorescent light Philips efficiency of 72lm / W, 36W fluorescent issued a total of 2,592 lumens , but the lighting efficiency of only 70 %, so the number of effective lumens lumens to 1814.4 , while the LED luminous efficiency of more than 130lm / W, Assumed to100lm / W, 18W can be achieved as long as 1,800 lumens , which is only half the power of fluorescent lamps can have the same brightness .And the LED luminous efficiency is also increased year by year .

3 . Power efficiency

Other than incandescent lamps because all are need for a dedicated power supply , power supply also affected the efficiency of the efficiency of the lamp .Below fluorescent lamps with Philips 's 36W T8 example . It 's rated output power of 36W, but because access to the magnetic ballast , the measured input power of 42.4W, which is loss of iron-core inductor has 6.4W, reduced to 85% efficiency , most made of iron-core inductor power In more than 10W , the power factor less than 0.512 . The LED 's are usually up to 90% power efficiency , a 18W to 20W LED fluorescent light

4 . Long life :

LED fluorescent light of a carefully designed life span of up to 50,000 hours . The life of a fluorescent lamp usually only 5,000 hours ( some made of fluorescent lamp life of 300 hours). Difference between the two nearly 10 -fold . The best long-life fluorescent lamps only 10,000 hours , the two also has a difference of 5 times.

5 . No mercury and no pollution.

We know that fluorescent lamps contain mercury . 36mm fluorescent lamps contain 25-45mg of mercury , 26mm (T8) contains 20mg of mercury. The fluorescent lamps are based on fragile glass as the shell , once broken glass , mercury will soon evaporate into the air , and instantly make the ambient air mercury concentration of 10-20 mg / cubic meter , exceeding the national The 1000-2000 times . The mercury is very harmful to the human body of toxic substances , mercury vapor up from 0.04 to 3 mg when will people in 2 to 3 months of chronic poisoning, up from 1.2 to 8.5 mg will induce acute mercury poisoning , should the amount of its 20 Mg , will directly lead to animal death . And 1mg of mercury is enough to 5454.5 kg of drinking water contamination , so it's not drinkable . The LED fluorescent lamp does not contain any toxic substances , is a completely pollution-free green light .

6 . Wide range of color temperature , color temperature of almost any can provide , but can also provide red, green and blue light as well as any color .

7 . Color index is high , the incandescent lamp color rendering index of 95 , fluorescent lamps for the 65-80 , while the LED fluorescent lamp can > 80 .

8 . There is no ultraviolet radiation .

9 . Non- glass, unbreakable , impact resistance, resistance to vibration .

10 . External isolated power supply of LED fluorescent lamps , the lamp can not reach both ends of high voltage electricity , only less than 36V DC safe voltage , there is no risk of electric shock , is a completely safe lamps .
