In recent years, LED tube has become one of the first LED lamps to enter the room, because it has many advantages over energy-saving lamps.

The following Ougexing Technology LED fluorescent tube engineering department will tell you about the 10 advantages of energy-saving LED tubes:

1. High luminous efficiency

The luminous efficiency of energy-saving lamps is about 55-80 lm/w (the luminous efficiency of Philips t8 energy-saving lamps is 72 lm/w), and the luminous efficiency of LEDs is above 100 lm/w. Recently, the new products of Curry in the United States are luminous The efficiency has reached 0 lumens/w, and it will continue to improve in the future. The difference between the two has now nearly doubled. In the future, it may reach more than 3 times.

2. High efficiency of lamps and lanterns

The efficiency of the lamp mainly refers to the effective light effect, because the energy-saving lamp emits light in 360 degrees, and the light emitted in the opposite direction is useless. Therefore, energy-saving lamps usually use a white lampshade, which can reflect a considerable part of the reverse light. Generally speaking, the efficiency of energy-saving lamps is only about 70%. The LED tube emits light at 120 degrees, so all light is effective light. Although the 120-degree light-emitting angle is sometimes a bit narrower, it is still sufficient in most cases. And the light-emitting angle can also be adjusted according to needs.

As mentioned earlier, the luminous efficiency of Ougexing's t8 energy-saving lamps is 72lm/w. The 36w energy-saving lamps emit a total of 2592 lumens, but the lamp efficiency is only 70%, so the effective lumens is 1814.4 lumens, and the luminous efficiency of LEDs has exceeded 0lm/w, assuming 100lm/w, then as long as 18w can reach 1800 lumens, that is, as long as half the power of the energy-saving lamp can have the same brightness.

And the luminous efficiency of the led tube is still increasing year by year.

3. High power efficiency

Because all lamps except incandescent lamps need a special power supply, the efficiency of the power supply also affects the efficiency of the entire lamp.

Take the 36wt8 energy-saving lamp as an example. Its rated output power is 36w, but due to the inductive ballast, the measured input power is 42.4w, that is, the iron core inductance loss is 6.4w, and the efficiency is reduced to 85%. Most domestic iron core inductance power consumption Above 10w, the power factor is lower than 0.512. The power efficiency of LEDs is usually as high as 90%, and an 18w LED tube only needs 20w input power. The power factor can also reach above 0.9.

Compared with energy-saving lamps, it can save more than half of the electricity, which means that an 18-watt LED tube can replace a 36-watt energy-saving lamp.

Not only that, but LED tubes have many other advantages:

4. Long life

The life span of a carefully designed LED tube can reach 50,000 hours. The life of an energy-saving lamp is usually only 5,000 hours (some domestic energy-saving lamps have a lifespan of only 300 hours). The difference between the two is nearly 10 times. The best long-life fluorescent lamp is only 10,000 hours, and the difference between the two is 5 times.

5. No mercury, no pollution

We know that all energy-saving lamps contain mercury. 36mm energy-saving lamps contain 25-45mg of mercury, 26mm (t8) contains 20mg of mercury. Energy-saving lamps use fragile glass as the outer shell. Once the glass is broken, the mercury in it will immediately evaporate into the air, instantly making the mercury concentration in the surrounding air reach 10-20 mg/m3, which exceeds the national level. 1000-2000 times the prescribed value. Mercury is a toxic substance that is very harmful to the human body. When mercury vapor reaches 0.04 to 3 mg, it will cause chronic poisoning within 2 to 3 months, and when it reaches 1.2 to 8.5 mg, it will induce acute mercury poisoning. If the amount reaches 20 Milligrams will directly cause animal death. And 1mg of mercury is enough to pollute 5,454.5 kg of drinking water, making it less than drinking standards. The LED tube does not contain any toxic substances and is a completely green and environmentally friendly light source without pollution.

6. The color temperature range is wide, almost any color temperature can be provided, and it can also provide red, green, blue and even any color of light.

7. The color rendering index is high. The color rendering index of incandescent lamps is 95, energy-saving lamps is 65-80, and LED tubes can be >80.

8. No ultraviolet radiation.

9. Non-glass products, not easy to break, impact resistance and vibration resistance.

10. The LED tube with an external isolated power supply can not touch the high voltage of the mains at both ends of the tube, and only has a DC safety voltage lower than 36v. There is no danger of electric shock, and it is a completely safe lamp.

Market disadvantages of LED fluorescent tubes

The only disadvantage of the current LED fluorescent lamp is the high price. However, although the current price of LED fluorescent lamps is about ten times that of fluorescent lamps, it is still cost-effective if it is related to its lifespan, power saving and pollution-free point of view. Because if compared with a fluorescent lamp with a lifespan of 5,000 hours, an led fluorescent lamp with a lifespan of 50,000 hours is already worth buying 10 times the price, and the energy saved in the meantime is a pure benefit. In Japan, because fluorescent lamps contain mercury, a broken fluorescent lamp has to pay the same amount of money as a new fluorescent lamp as a toxic substance disposal fee. Therefore, even if long-life (10,000 hours) fluorescent lamps are used in Japan, the cost is equivalent to 10 times more expensive LED fluorescent lamps.
