As dimmable LED tubes become more and more popular, we would like to share some information about dimmable led tube. In fact, dimmable LED lights are often a better alternative than fluorescent lights, because they produce a large amount of light and are usually less expensive than a dimmable fluorescent light. Dimmable LED lights can range in size from dimmable LED Christmas light bulbs to dimmable recessed lights. As popularity of these LED lights grows, the number of available shapes grows along with the demand. LED lighting can be for indoor or outdoor fixtures and, in most cases, requires no more tools to install than other types of light fixtures. All home improvement and lighting stores carry LED lights with dimmable features, as do both large and small retailers.

It was dark and cold outside. A man walked around this neighborhood alone wanting to find a house where could offer him some food and a bed as he had been walking for a long time to get here. Five hours ago, he was driving his brand new car on the expressway for a prom and suddenly his car broke down and he had to walk to somewhere to ask for help. There were no hotels or telephone booths nearby and when he saw this neighborhood, he knew it was a poor residential area. No bright lights on the street, but only few broken dim lamps. The houses were even more frightening because the man barely could see the light in these dilapidated houses.

He looked around the area and surprisingly found a house which turned the light on. He ran toward that house and knocked on the door. After he talked about what he had been through, the owner invited him into the house and agreed to let the man stay one night. The lucky man came into the house and somehow he felt relief and everything in the house made him feel at home. He noticed that even though the whole living room merely had one light tube, the house was still bright enough at night. It was an led tube lamp but why this poor family would be willing to buy an LED tube when others even refused to turn on the light at night let alone buying an LED light. 
The house owner gave a glass of water and pieces of bread to the man and talked to him with shame "I'm sorry that we don't have too much food at home. We only have some bread."
"No, no, you are very kind of me. I very appreciated that you take me in. Could I ask a question if that won't offend you? Why you would rather use a t8 led tube light than buy an inexpensive lamp to save some money?" said, the man. 
"Actually, we did need saving money, but we think light is more important for our life. Bright light brings hope to people. We are poor and we may not have many things but hope is the only thing we should have. The LED reminds our family that we should not lose hope anytime. Besides, the led tube light saves much energy than traditional incandescent lamps."

Sometimes, you will be surprised that a simple LED tube light bears such profound meaning for people. There is no doubt that darkness expands evil and fear when brightness stimulates hope and courage.

What is a LED?

LED stands for “Light Emitting Diode”. An LED is a semiconductor lighting source and as the name states, a t10 led light is a diode. A diode is a semi-conductor device that permits current flow in one direction. Semiconductor diodes are a junction of two materials. One material has a surplus of positive charge (holes), and the other a surplus of negative charge (electrons). When one applies a forward voltage, the electrons and holes are brought together. They combine and release light energy (photons), thus becoming a Light emitting diode.

Efficacy of LED devices continues to improve, with some chips able to emit more than 100 lumens per watt. LEDs do not emit light in all directions, and their directional characteristics affect the design of lamps. The efficacy of conversion from electric power to light is generally higher than for incandescent lamps. Since the light output of many types of light-emitting diodes is small compared to incandescent and compact fluorescent lamps, in most applications multiple diodes are assembled.

Do LEDs Emit IR Or UV Radiation?

In contrast to most light sources,led tube lamps radiate almost no heat in the form of IR (Infrareds) that can cause damage to sensitive objects or fabrics. Wasted energy is dispersed as heat through the base of the LED. 

Also, LEDs (unless designed otherwise) emit minimum UV radiation, which has led to a widespread claim that LED lights do not attract insects. The fact is LED lights attract less insects due to emitting almost no radiation on the ultraviolet range, which specially attracts insects, but on an area with no alternatives source of light, and a population of insects, the LED light will still attract them, so don’t expect miracles.

Why LEDs Use Little Power?

General-purpose lighting needs white light. LEDs emit light in a very small band of wavelengths, emitting light of a color characteristic of the energy bandgap of the semiconductor material used to make the LED. To emit white light from LEDs requires either mixing light from red, green, and blue LEDs, or using a phosphor to convert some of the light to other colors.LEDs generate light very efficiently, with minimum losses in heat. Filament based lighting consumes more power than the light produced because a great part of the power is emitted as heat. Moreover, LEDs are directional, which means they can focus the light in any pattern wished, thus delivering the entire light output to the desired area, with no loss of light, and therefore, does not need to generate as much light output to illuminate the same area with the same results.

LED technology is high efficiency, cost effective, energy efficient and environmental friendly. Our goal is to keep on researching and developing super LED light, to offer a bright world. We will let the world know that "Green starts ERVAN ". 

First, high reliability especially as the drive power LED lights which installed at high altitude, convenient maintenance, maintenance cost is also large.
Second, high-efficiency LED energy-saving products, and drive power efficiency is higher. For power installed in the fixture structure is particularly important. Because the LED luminous efficiency increases as temperature decreases LED, led tube lamp of the cooling is very important. Power, high efficiency, its power consumption is small, the heat in the fixture is small, it reduces the temperature rise of the lamp. On delaying the LED light decline favorable.

Third, high power factor of the load power factor is the power requirement. Generally less than 70 watts of electrical appliances, there are no mandatory targets. Although power is not a single low point with the electrical power factor has little effect on the grid, but at night we light a lamp and similar load are too concentrated, the grid will produce more pollution. From 30 watts to 40 watts of LED drive power, it is said in the near future, perhaps would have some power factor of the indicator.

Fourth, drive traffic there are two: one is a constant source for multiple constant current source, constant current source for each channel individually to each LED power supply. In this way, the combination of flexible, all the way LED failure does not affect other LED's work, but the cost will be slightly higher. The other is a direct constant current power supply, LED in series or parallel. It has the advantage of low cost, but that flexibility is poor, but also to solve an LED failure does not affect other LED running issue. These two forms coexist for some time. Multi-channel constant current output power supply, in terms of cost and performance will be better. Perhaps the future direction of the mainstream.

Fifth, surge protection. LED Surge capacity is relatively poor, especially anti-reverse voltage capability. Enhance this protection is very important. Some LED lights installed in the outdoors, such as led tube bulbs. Since the start grid load rejection and lightning induction, from the grid system will invade a variety of surge, surge can cause some damage to the LED. LED drive power supply should therefore invasion of surge suppression to protect the LED's ability to not be damaged.

Sixth, protection functions in addition to conventional power protection features, the best increase in the constant current output LED temperature negative feedback to prevent LED temperature is too high.
Seventh, protection aspects of lighting and outdoor installation type, the power structure to be waterproof, moisture, shells and Fast.
Eighth, drive power of life and the life of the LED to be adapted.
Ninth, to meet safety and electromagnetic compatibility requirements.

We have a strong engineer team which composed of 16 individuals with perfect designers. Our management system is strictly conducted according to ISO9001-2008 standard. We always stay ahead of this field because of our talented creativeness, like Unique designed structure and attractive appearance, stable quality proved by TUV/CE/RoHS/FCC and UL certificate.

First, T8LED fluorescent lamps do not use mercury, and they do not contain lead. The traditional fluorescent lamps contain a lot of mercury vapor. Once they were broken, the mercury vapor will evaporate into the atmosphere, which will pollute the environment. On the contrary, the led tube lamp which can well protecte the environment, is recognized as one of the green lights.

Secondly, T8LED fluorescent lamp is a cold light source, unlike traditional lamps that emit a lot of heat. It is basically able to convert all electrical energy into light energy, will cause waste of energy, very economical.

Again, T8LED fluorescent lamp is a very quiet, energy-saving lamps, does not like the noise, like the traditional fluorescent lamp, ideal for applications requiring a quiet environment, such as libraries, places like the office. Also an excellent way to protect the eyes, start very fast, no flickering, very beneficial for our health.

Additonally, because 
T8 led lights are green fluorescent lamps which do not produce ultraviolet light, infrared light and other radiation. Besides, they have no mercury and other harmful substances, which can avoid the mosquitoes around the lamps so as to create a relatively clean room environment.

Finally, T8LED fluorescence lifetime is very long, its power consumption is less than one-third of the traditional fluorescent lamp, but the brightness but with the traditional fluorescent lamp is the same. In general, the normal use of more than thirty thousand hours of life, long-term use without replacement, invisible to reduce labor costs, it is suitable for the occasion some inconvenience to replace the lamp. Of course, LED fluorescent tube color is very rich; you can produce a variety of luminous colored lights to meet the needs of different occasions.

T8LED up to 80% energy saving lamps, lamp life of more than 10 times, almost maintenance free, there should always replace the lamp, ballast, starter problems, about six months down the cost savings can exchange costs. Environment-friendly semiconductor light source, light and soft, pure spectrum in favor of workers eyesight and physical health, 6000K cool white light gives a cool visual experience and helps to focus and improve efficiency.

Because the upsurge of global energy’s price, LED has become a popular industry which is energy-saving. More and more intra-manufacturers pay attention to the market of LED.

Prospects for the future development of LED
First, market showed negative growth
By influence of the global financial tsunami, power of consumption fell substantially. The consumers delay or reduce to buy related electronic products. Enterprises also reduced advertising expenditures and capital expenditures, which will make the LED market demand slipping. With Christmas lights. For example, in the markets in Europe past, consumers always purchase a new string of lights every year, which create billions of dollars per year. But by the financial turmoil, consumers reuse previously purchased products or reduce the purchase quantity, making Christmas lights market shrinking dramatically. Although there is a big negative impact, the function of LED still attacks consumers. And the LED energy-saving, multi-color, long life and other characteristics create consumers, which will make more active use of LED system vendors.

Second, government investment drives market demand
In order to save the global economic boom, governments continue to expand public construction investment. They expected to drive economic growth. In various public construction investment, including street lighting, urban landscape lighting, indoor and outdoor lighting in public buildings are the focus of national government investment. This is the point whether LED can pass "economic winter" or not.

Third, unit price continues to decline
Analyze the external environment, LED need to narrow the price gap to expand the application markets and market penetration.

Fourth, lighting market will continue to grow
For the LED industry, the lighting market is the largest potential market. And with increase of LED luminous efficiency and government’s subsidies or incentives, there are more and more applications field use LED instead of the traditional light.

Fifth, accelerate market applications
LED applications continue to expand, as well as the structure of the LED light, emitting principle and luminescence characteristics, which are different from traditional light. The standard of LED gradually valued by the market, governments and industry associations actively involved in the development of this field.
