LED Tube Light And The Difference Between Ordinary Incandescent

Edit:Alite Co.,Ltd  Date:Sep 11, 2017

Said LED energy saving, are relatively traditional incandescent. Because the LED is the principle of diode light, the energy conversion into light energy efficiency is much higher than incandescent. Specifically, the former is about 65%, the latter may be as low as only 5%! The rest are used to heat up. This is the reason why energy-saving led lights, and then led lights and ordinary incandescent and what is the difference? May be a lot of people know that there are several kinds of lights, but also know the effect of energy saving are LED energy-saving lamps, energy-saving lamps, incandescent. But the principle of one must not everyone understand.

Ordinary incandescent light effect is about 10 lumens per watt, life expectancy of about 1000 hours or so, it works: When the light access circuit, the current flows through the filament, the thermal effect of current, so that incandescent light issued a continuous visible light and Infrared, this phenomenon in the filament temperature rose to 700K can be aware of the work of the filament temperature is very high, most of the energy in the form of infrared radiation wasted, because the filament temperature is high, evaporation is also fast, so life also Large and shortened, about 1000 hours or so; on the perspective of energy saving, the traditional incandescent lamp due to a large number of infrared energy loss and high temperature heat, short life, advanced energy-saving environmental protection lamp is an inevitable energy-saving revolution The

In contrast, energy-saving green light is mainly through the ballast to the lamp filament heating, about 1160K temperature, the filament began to launch electrons (because the filament coated with some electronic powder), the electronic collision of argon atoms produce inelastic Collision, argon atoms collide with the energy and then hit the mercury atoms, mercury atoms in the absorption of energy after the transition to produce ionization, issued 253.7nm UV, UV excitation phosphor luminescence, because the fluorescent lamp temperature of the filament in the 1160K or so, than incandescent The work of the temperature 2200K-2700K much lower, so its life is also greatly improved, and the degree of energy saving, life expectancy of up to 5000 hours or more, because it does not exist incandescent current heat effect, the energy efficiency of the phosphor is also very High, reaching 50 lumens per watt above.

LED (Light-Emitting-Diode means a light-emitting diode) is a kind of energy can be converted into visible light semiconductor, it changed the incandescent tungsten light and energy-saving lamps three primary colors of light principle, and the use of electric field light. As the led is the use of solid-state semiconductor chip as a luminescent material, and we used in the daily life of the bulb is made of metal luminescent materials, so the energy issued by the different, according to statistics, a red LED light to a certain brightness When the energy required is 15 watts, while the traditional light bulb to achieve the same measure will consume up to 150 watts of energy; the other according to scientists, LED power to light, 10% of the energy can be converted into light energy, and Incandescent bulb conversion efficiency is only 7-8%, it can be seen, to achieve the same lighting effects, LED lights than incandescent energy is obvious.

According to the analysis, LED features are very obvious, long life, high luminous efficiency, no radiation and low power consumption. LED spectrum almost all concentrated in the visible light band, the luminous efficiency of more than 150lm / W (2010). The results show that the luminous efficiency of ordinary incandescent lamp is 12lm / W, the life is less than 2000 hours, the luminous efficiency of spiral energy-saving lamp is 60lm / W, the life is less than that of ordinary incandescent lamp, spiral energy saving lamp and T5 trichromatic fluorescent lamp. 8000 hours, T5 fluorescent lamp was 96lm / W, life of about 10,000 hours, while the diameter of 5 mm white LED light effect can be more than 150lm / W, life can be greater than 100000 hours. It is also predicted that the future of LED life limit will be infinite, will also dominate the market.
