Why do LED lights use such little power?
  LED lights (T8 LED tube, T10 LED tubes) donot use a filament where a conductor is heated and light is created. Filament based lighting consumes more power than the light produced. LED lights produce very little amounts of heat and do not use filaments making them far more efficient in consumption and output.


How long do LED tubes last?
  LED tubes are rated by manufacturers to operate under normal conditions for approximately 5 years or 50,000 hours of continuous use. As LEDs get older, they tend to dim and fade but aren't susceptible to blinking like incandescent or fluorescents.


How to avoid the light pollution? Commercial led lighting will be your best partner to solve the lig
 

Many people have come to realize the dangers of outdoors light pollution, but indoor light pollution problems are still not paid  enough attention. In fact, Poorly designed of Indoor Lighting will cause a certain extent of light pollution, affecting the liver’s health.


There are various reasons caused indoor light pollution, but what are the real reasons by the lighting design? At present, many consumers have errors on the interior lighting design, Mainly in the excessive lighting, lighting is too bright or too dark, the color complex, in fact, These problems can be avoided in the lighting design. "


Many consumers use a lot of lighting in pursuit of decorative effect. In fact, General lighting decoration budget should be within 5% of the total project total cost budget, excessive decorative lighting not only occupants eye fatigue, decreased vision, what’s more it also harmful to the human’s eye cornea  and   it may cased iris damage.


As a result ,people who may  suffered from dizziness, fatigue and other physical symptoms like neurasthenia.  In  another way the overly bright or dark lighting, will make the occupants as fatigue or decreased vision, increased incidence of cataract. And there are many consumers like colorful lights. In fact, these colors messy lighting, not only   harmful to vision, but also interfere with the brain central nervous system function.


"light pollution" of Indoor lighting should not be overlooked, so are there any way to avoid its adverse health effects?   Here   are   some  suggestions  from  lighting  design  experts.


Firstly, when choose the lamp including led downlight fixtures, led flat panel light and linear led tube, you should choose those with high color, high-strobe, stable performance characteristics. Such as fluorescent lamps with electronic ballasts, LED lamp and so on. the commercial led lighting in High CRI , moderate, spot no flare, no aperture of, can help you see the authenticity of the object to and comfortable; high strobe LED Lighting can reduce eye fatigue; stable performance and high efficiency lighting can make driver long lifespan, greatly increasing the overall stability.


Secondly, with guarantee the normal lighting you can reduce pollution through the ingenious arrangement of lamp. Such as concealed installation of lighting, avoid exposing the high points of light. In addition, selecting the anti-glare led lighting can significantly reduce the glare caused by light pollution.


Thirdly, using indirect light adequately,for example, use the lights reflected off the ceiling and in this way,light is both uniform and comfortable. it is better to use where indirect lighting in a ceiling or light-colored ceiling and require a relatively high illumination uniformity.


Topvirtue Lighting specializes in researching and manufacturing LED residential and commercial lighting, ranging from LED kitchen lights, LED Panel Light, LED Tube light, who only focuses on American Market! , T8 LED Tube Light and LED Flat Panel enjoy the high CRI, stable performance. Topvirtue Lighting not only manufacture high grade LED Commercial Lighting ,but also help you how to do the interior lighting design and avoid the light pollution.



Benefits of LED Lighting
 

LED Lighting is More Efficient
One of the main benefits to LED lighting is that it is more efficient. You can get more life out of each bulb and it is also energy efficient so it helps the environment, too. When it comes to LED lights, you've probably seen these before even if you did not realize what you were seeing.


Longer Lifetime
Yet another one of the best benefits of LED lighting is that they are built to last. They have a much longer lifetime than your average bulb and you can use this to your advantage in many ways. Not only does it help you save from purchasing and replacing lights but it also means you can put them in places that are more difficult to reach or would be more trouble to replace often. Now that you can see some of the most common benefits of LED lighting, it's a bit easier to see why more and more people are choosing LEDs for their lighting options. It just makes sense when you can get more for your money and get a longer lasting, more efficient light source instead.


Not Restricted by Size
Another great benefit to LED lighting is that there are fewer to no restrictions on size. Unlike other types of lighting, LEDs are not restricted by size. They can be as small as 2mm in size or less which makes it possible to use them in places you could not use an ordinary bulb or lighting source. This opens up many doors of opportunity to how you will use your LEDs.


Variety of Color
Another benefit to LED lighting is that it is easier to get a wide array of color that cannot always be done with regular bulbs. They don't require filters to produce the different colors, due to how the diodes are constructed. This makes it much easier to get them in nearly any color you can think of, even neon shades. This is why you see LEDs in such a wide variety of color options used in so many different places.



Talk about the reason of LED products’ light attenuation.
 

LED products' light attenuation means the light signal is fading during the transmission. Now the light attenuation of the LED products which produced by global LED manufactories is different. High power LED also have light attenuation, that is related directly to temperature and mainly decided by chips, phosphor and encapsulation technique. At present, the light attenuation of white LED in the market maybe one of the primary problems that constraint the LED products march in residential lighting.
 
Now, Topvirtue  Lighting which specializes in researching and manufacturing LED residential and commercial lighting, ranging from LED kitchen lights, LED Panel Light, LED Tube light, who is not only a products factory but also an excellent solution supplier will give an analysis that there's two factors causing LED light attenuation:

First, the reason of LED's quality.
Adopting bad LED chips cause the luminance fading fast.
The production process exist some flaws. The heat of the LED chip can't diffuse well from the PIN feet. That causes the high temperature of the chip and aggravates light attenuation.

Second, the reason of using a condition.
LED always use constant current driver but someone may adopt constant voltage driver that makes the excessive LED light attenuation.
The driver's current is higher than rated requirement.

In fact there are many reasons that cause LED products' light attenuation. The heat is the key problem. Many factories don't care about the heat dissipation but after a long time the shoddy goods they produced will appear a serious light attenuation. The thermal resistant of the chip, the effect of the sliver colloid, the heat dissipation of the aluminum circuit board, colloid and gold thread all can influence on the light attenuation.
