Energy-saving lamps and led lights can often be heard in life. The use and conversion methods of these two lamps are the same. So what is the difference between them? Below GO Jiaju takes you into the world of energy-saving lamps and LED lights.
What is an energy saving lamp?
The energy-saving lamp is also called compact fluorescent lamp (referred to as CFL lamp in foreign countries), which has high luminous efficiency (5 times that of ordinary light bulb), obvious energy saving effect, long service life (eight times that of ordinary light bulb), small size and convenient use. Its working principle is basically the same as that of fluorescent lamps. When the tungsten wire is energized and heated, it will generate electrons, and use certain technical means to accelerate the electrons. The lamp of the energy-saving lamp is designed as a vacuum filled with mercury, ie mercury. The accelerated electrons interact with the vaporized mercury atoms to produce ultraviolet light. A fluorescent substance is applied to the energy-saving lamp tube, and ultraviolet light is irradiated onto the fluorescent substance to generate light.
What is a led light
Light Emitting Diode, also known as a light-emitting diode, is a solid-state semiconductor device that converts electricity directly into light. The heart of the LED is a semiconductor wafer with one end attached to a holder, one end being the negative pole and the other end connected to the positive pole of the power supply, so that the entire wafer is encapsulated by epoxy. The semiconductor wafer consists of three parts, one part is a P-type semiconductor, in which the hole dominates, and the other end is an N-type semiconductor, where it is mainly electrons, and the middle is usually a quantum well of 1 to 5 cycles. When a current is applied to the wafer through a wire, electrons and holes are pushed into the vector sub-trap. In the quantum well, the electrons recombine with the holes, and then the energy is emitted in the form of photons. This is the principle of LED illumination.
LED lamps have many advantages such as small size, low power consumption, long life, non-toxic and environmental protection, etc. LED lamps are gradually developed from outdoor decoration and engineering lighting to home lighting.
The difference between energy-saving lamps and led lamps
In addition to the principle of illumination, LED lamps and energy-saving lamps have very significant differences in environmental protection, energy saving, service life and stability. Compared with energy-saving lamps, LEDs are more energy efficient.
The energy consumed by LEDs is 25 percent of energy-saving lamps. This is because ordinary energy-saving lamps still consume a portion of the electrical energy and convert it into heat, while LED lamps do not have this problem. LED lamps have a longer service life, and quality LED bulbs can last for 10,000 to 20,000 hours, while the same energy-saving lamps have a service life of between 6,000 and 10,000 hours.
LED lights are more environmentally friendly. Mercury is one of the indispensable luminescent materials for energy-saving lamps. As the use time increases, the sealing performance of energy-saving lamps will be gap, and mercury will be volatilized into the air, causing pollution to the air.
LED lights have no such problems at all, and they are safe and environmentally friendly. LED lights far exceed the energy-saving bulbs in terms of seismic and lightning protection. Continuous switches caused by voltage instability have far less impact on LED lights than energy-saving lamps. If the energy-saving lamps are frequently switched, the service life will be greatly reduced.
A major reason for the current LED blocking is that the price is too expensive. For ordinary users, the performance of the service life, energy saving and environmental protection cannot be visually observed after all. The only thing that can be intuitively perceived is the price. However, considering the advantages of the above LED lamps, the cost of installation is also acceptable. The service life is so long after all, and the stability is not easy to break. In the long run, it is definitely more cost-effective than buying energy-saving lamps.
