Do you know the difference between LED and incandescent lamps?
1.the luminescence principle is different
Incandescent LAMP WORKING PRINCIPLE IS ELECTRIC CURRENT THROUGH THE filament to produce heat, spiral filament will constantly gather heat, make the temperature of the filament amounts to 2000 degrees Celsius above, filament in incandescent state, like burning red iron can light up and give out light.
LED lights, also known as light-emitting diodes, are solid-state semiconductor devices that convert electricity directly into light. The heart of the LED is a semiconductor wafer, one end of which is attached to a holder with a negative terminal and the other end connected to the positive terminal of the power supply, so that the entire wafer is encapsulated in epoxy resin.
2.The thermal radiation produced is different.
The heat of an incandescent bulb is felt in a short period of time, and the higher the power, the more heat. The electricity is converted into part light and part heat. LED electrical energy into light energy, heat radiation is very little, most of the ability to directly convert into light energy, and the general lamp power is low, coupled with the heat dissipation structure, compared with incandescent lamp, LED cold light source heat radiation is better.
3.The lights are different.
Incandescent lamps emit light of all colors, but the ratio of colors is determined by the luminescent substance and temperature. LED is a kind of green light source, LED lamp DC drive, no strobe, but also no infrared and ultraviolet components, no radiation pollution, relatively high color and has a strong light direction
Not only that, LED light dimming performance is good, color temperature changes will not produce visual errors, coupled with the cold light source of low heat, can be safe to touch, it can not only provide a comfortable light space, but also can well meet the physical health needs of people, is to protect eyesight and environmental protection of health light source.
