If a LED light bulb and an incandescent bulb have the same voltage, emit same amount of light, how much longer would LED last? Please help me explain. Thank you so much! =D
long lifespan depends on the high tech of the chip, not the voltage and luminance. LED light is more energy-efficient than incandescent lights, because it can produce the same amount of light with less power consumption. i.e. power saving. I suggest you can try BYB LED lights, they are more attractive in price and quality.
It is a good idea to perform the experiment with LED lights at home, take LED light, now other incandescent light. In separate room apply them for one month, now observe which is better, and which last long time. What I researched this from the Autopal which gives this idea to know what is the LED and How it is important.
Incandescent bulbs: Create light by passing electricity through a metal filament until it becomes so hot it glows. Incandescent bulbs release 90% of their energy as heat. LED lighting products use light emitting diodes to produce light very efficiently. The movement of electrons through a semiconductor material illuminates the tiny light sources we call LEDs. A small amount of heat is released backwards,into a heat sink, in a well-designed product; LEDs are basically cool to the touch. Visit us in:ledlighting.efftronics.in/ledlights/
LED lights last around 50000 hours, whereas CFLs are about 10000 hours and incandescent last around 1000 hours. LED lights are also much more efficient than other light sources. An incandescent bulb emits energy at all different wavelengths, only about 10% of which is actual light. This means a 100 watt incandescent bulb will produce only about 10 watts of actual light. Most of the energy is infrared or heat. An LED bulb emits around 80% light, so a 100 watt LED bulb will emit 80 watts of light. That's why you can replace a 100 watt incandescent bulb with a 12 watt LED bulb 100 watt incandescent = 10 watts of light 12 watt LED = 9.6 watts of light The reason LED's last so much longer is that they have no filament to burn out. Since they run on DC, they have an electronic driver to convert the AC to DC. The electronic driver is usually what fails, due to its own overheating or normal life expectancy.
