Edison invented the electric light bulb mankind farewell to the darkness and into the light. The original light bulb is what we now call the incandescent lamp. Incandescent effective utilization of energy is very low, only about ten percent of the electrical energy is converted into light, the rest of the electrical energy is converted into heat and disappeared in the air. With the progress of time, energy-saving lamp invented by people, energy-saving lamps. CFLs produce convenient, cost cheaper, more energy-efficient compared to incandescent lamps, more light, thus gradually replace the incandescent lamp, become the mainstream choice for indoor lighting. LED lights in recent years, is emerging as a means of illumination. LED lights than energy-saving lamps is a technical advance, it can be said LED is the future direction of lighting the lamp.
The main light-emitting material energy-saving lamps is still a tungsten filament. The principle is that heat will produce tungsten powered electronics, the use of certain techniques, accelerating electrons. CFL lamps are designed to vacuum, which is filled with mercury, which mercury. Electronic and atomic force mercury evaporated by accelerated, resulting in ultraviolet light. In the energy-saving lamp coated with a fluorescent material, an ultraviolet light is irradiated on the fluorescent substance is produced light.
LED is the abbreviation of light emitting diode. The main component is an LED lamp can convert electrical energy into light energy into a semiconductor, with silver or gold wire and cable to connect it to the circuit board, epoxy sealed to protect user around the same time, the protective casing being placed above the overall .
LED lights and energy saving lamps in addition to the light-emitting principle different in environment protection and energy, life, stability aspect also has a very significant difference. Compared with energy-saving lamps, LED more energy efficient. LED energy consumption is twenty-five percent of energy-saving lamps, this is because the average consumption of energy-saving lamps are still a part of the electrical energy into heat, while LED lights do not have this problem. LED lamp life longer acceptable quality LED lamp life can reach 10000-20000 hours, while the same energy-saving lamps, its life between 6000-10000 hours. LED lights more environmentally friendly. Mercury is one of the energy-saving lamps is essential for light-emitting materials, as time goes on, there will be energy-saving lamps sealing cracks in which mercury will evaporate to the air, pollute the air. LED light is no problem in this regard, the use of safety and environmental protection. LED lights on the seismic performance of the mine far more than energy-saving bulbs. Effect of continuous switching voltage instability caused by the LED light is much less than the energy-saving lamps. The energy-saving lamps if frequent switching, life will be greatly reduced.
A major reason for the current caused by the promotion of LED obstruction is too expensive for the average user, life, energy saving and environmental protection, after all these properties can not be observed visually, intuitively be felt only prices. However, considering the above-mentioned advantages of LED lights, its installation cost is acceptable, there is life after so long, stable and easy to bad, in the long run, the absolute cost-effective than buying energy-saving lamps.
