What’s the features of the LED tube by comparison of the traditional fluorescent

In recent years, with energy saving receiving increasing attention and the substantial increase in electricity consumption , coupled with LED technology matures , more and more people pro-gaze LED energy-saving lamps, it will replace the traditional fluorescent lamps sooner or later. So what is exactly advantage of the LED tube light opposed to  the traditional fluorescent ?

LED tube

1, LED tube , energy saving

Traditional fluorescent lamps contain a lot of mercury vapor, if broken,the mercury vapor will evaporate into the atmosphere. But then there is nothing mercury in the LED tube and LED products do not contain lead, which play a protective effect on the environment . LED fluorescent is recognized as the green lighting in the 21st century.

2 , efficient conversion, reduce heat

Traditional lamps produce a lot of heat , and LED lighting of which the Semiconductor light-emitting diodes is adopted as the lighting principal contributes to the energy conversion , which cause less energy waste. But also there is no fading phenomenon on documents, clothing.

3 , quiet and comfortable, no noise

LED tubes do not produce noise, which is a good choice everywhere the sophisticated electronic equipment is used,which is particularly suitable for libraries , offices and the other indoor occasion.

4 , soft light, protect your eyes

Traditional fluorescent lamp using AC produce 100-120 times strobe per second . LED lighting directly converse the AC into DC, no flicker , protect the eyes.

5 , no UV, no mosquitoes

LED lamps do not produce ultraviolet light, so it is not the same as the traditional lamp that there are a lot of mosquitoes around the light source side. Interior will become more clean and sanitary and clean .

6, the voltage adjustable 80V-245V

Traditional fluorescent lamps is lightened up by the high-voltage rectifier released, and when the voltage is lowered, it is hard to light up the lamp. The LED lamps can be lit in a certain range of voltage, but also adjust the brightness.

7 , energy saving , longer life

The power consumption of LED tube is one-tenth less of the traditional , life expectancy is 3 times that of traditional fluorescent lamp,it can be used for long time without frequently replacing  so that reduce labor costs. It is the perfect lighting for the occasion where it is difficult to replace the lamp.

8 , rugged solid , long-term use .

The light body of LED light is made of epoxy rather than using a traditional glass, which is more robust, secure , even hit on the floor,the LED light will not be easily damaged, it can be safely use .

9 Compared with ordinary fluorescent lamps , LED tube light without ballast, no starter , no flicker .

10 maintenance-free, frequent switching does not cause any damage.

11 safe and stable quality can withstand 4kv high voltage, low heat dissipation can work between  the low temperature -30 ℃ and temperature 55 ℃.

12 the surrounding environment will not be affected . No ultraviolet and infrared, no hazardous materials such as mercury , eye protection , and no noise.

13 Vibration resistance is good, easy to transport .

Definitely, the current worldwide advocates the energy conservation , LED tube light as a new energy saving, environmentally friendly and green lighting products, will completely replace the traditional lamps in the future.

But there is disadvantages that LED tubes compare with the ordinary fluorescent lamp with as follows: expensive,there is a great gap between the theoretical optical efficiency and the light efficiency that can presently generally be done, the practical life is unable to reach the current theory life,strengthened Cooling function is a puzzle that urgently need to be resolved , the light fade also yet to be significantly reduced.

But relatively speaking, the LED tube light has the unparalleled advantages over the traditional fluorescent lamp, it is not only energy efficient , “longevity lights “, but the applicability is good , small size , suitable for decoration . Low carbon and environmental protection , less harmful qualities , waste can be recycled , colorful , pure light color, a narrow spectral range and use of RGB color theory that are the red , green and blue , under the control of computer technology , it can mix and match any different color,the light color is changeable.

Nowadays,the LED flood lights and LED tube light are the most widely used as the representatives of the decorative lighting and the home lighting in daily life,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood lights are mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness is needed to illuminate,meanwhile,there a large number of factory engaging in developing and producing the LED light,Lead Lighting is just one of them,which adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood lights so that fully guaranteed stable and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood lights, while low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of the LED tube light and LED flood lights and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is Known as energy-saving and environmental protection. Login http://www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com  to know more awesome LED flood lights and other LED lighting.

What are the three Myths of the LED tube light we must pay attention to

LED tube, LED ceiling light , LED downlight , LED bulbs , LED candle lights , the brightness is measured with the luminous intensity, the luminous intensity refers to the he luminous intensity in the direction of normals(cylindrical axis for the column tube) ,which is  the emitted luminous at flux unit solid angle, the unit is Candela .

Myth one : the greater the power, the higher the brightness

What measure the brightness of LED tube is the luminous intensity,which refers to the luminous intensity fingering line in the direction of normals (cylindrical axis for the column tube ),which is the luminous flux emitted at the per unit solid angle,the unit is Candela . Because the emission intensity of LED tube light is generally small, so milli- Candela is used for the luminous intensity unit . Typically , the light source emit the luminous flux with the different intensities in different directions,the visible radiation intensity emitted in a particular direction at per unit solid angle is called light intensity, referred axial brightness. The greater the power of LED tube light ,it is not the higher the brightness is, so we should concern about its axial brightness rather than power when we buy LED fluorescent.

LED tube

Myth: The actual light angle is regarded as the effective angle

The emitting angle of the LED ceiling light is divided into effective and practical light angle . Luminous intensity is the effective angle between the half of the value of the direction of the axial strength and the light emitting axis ( normal ). the angle that is 2 times more than the Half-value angle ( or called half-power angle ) is the actual light angle . because the light that is too weak in the other half of the angle of the axial strength is not included in the effective angle in practice . So we should be concerned about the actual emitting angle when purchasing products. The quantities of the Products Computational Engineering Use subject to actual light angle , the effective light angle can be used as reference values.

Myth: high expectations for real life

LED manufacturers predict the theoretical life of the LED light is up to 50,000 hours MTBF (mean time between failures , the standard the manufacturers measure the life of conventional lamp source ) , but which is the same as all of the basic light sources , LED’s lumen depreciation decay over time. Therefore, although lighting time of the LED ceiling can be very long , MTBF is not the only consideration in determining useful life. The lumen depreciation of the LED ceiling is affected by numerous environmental conditions such as ambient temperature, humidity , and ventilation , Lumen depreciation is also under control , thermal management , current levels, and many other electrical design considerations. When promoting the LED, many sales for some reason may be provide customers with some vague information , misleading , such as the life of the LED tube light is 50,000 hours or so, the 50000 hours is the theoretical life of the LED lamp manufacturers expect, as a lighting source, lamp brightness is always gradually decaying and darkening, which refer to the light fades . In application-level LED tube , the light fades is more than 50 %, the human eye can clearly feel the change in brightness , we believe the brightness at this time does not apply to lighting. Having used the low-cost LED tube about three to six months , many producers and engineering companies often find the brightness of LED tubes is significantly less bright than just installed , and even almost non-existent , it is because the light fades of LED tube is not taken into account. In summary , we have to pay attention to its light decay rate rather than the use of time when buying LED tube light.

Nowadays,the LED flood lights and LED tube light are the most widely used as the representatives of the decorative lighting and the home lighting in daily life,the LED tube light enjoys a great popularity in our corridor, restaurants, shopping, leisure and entertainment, galleries, exhibition halls and other indoor environments everywhere, the LED flood lights are mainly used in city squares, parks, stadiums, the facades of large commercial buildings and hotel, stage, waiting rooms, airports etc. where the higher brightness is needed to illuminate,meanwhile,there a large number of factory engaging in developing and producing the LED light,Lead Lighting is just one of them,which adopts high brightness SMD as the light source of the LED tube and highly integrated and high brightness COB as the light source of the LED flood lights so that fully guaranteed stable and soft light of the LED tube light and octahedron breadth and brightness irradiation range of the LED flood lights, while low voltage constant current driver ensure the AC can be converted into the DC to improve energy efficiency of the LED tube light and LED flood lights and reduce the waste heat energy and stroboscopic effect exciting the human eye, the most important is that the LED lighting without adding mercury and other heavy metals harmful to our body and pollution the environment, that’s why the LED light is Known as energy-saving and environmental protection. Login http://www.ledclan.com to learn more features and uses of the LED tube light and surf www.lead-lighting.com  to know more awesome LED flood lights and other LED lighting.
