Edison invented the light bulb to make people say goodbye to the darkness and walked into the light. The original light bulb is what we call incandescent lamps today. The effective utilization of electric energy by incandescent lamps is very low. About 10% of the electric energy is converted into light energy, and the rest of the electric energy is converted into heat energy and disappears into the air. With the advancement of the times, energy-saving lamps have been invented by people, energy-saving lamps. Energy-saving lamps are easy to manufacture and cheaper. They are more energy-efficient and brighter than incandescent lamps. Therefore, they have gradually replaced incandescent lamps and become the mainstream choice for indoor lighting. LED lights are an emerging lighting method in recent years. LED lights are a technological advancement compared with energy-saving lamps. It can be said that LED is the development direction of future lighting lamps.
The main luminescent material for energy-saving lamps is still tungsten wire. The principle is that the tungsten wire generates electricity after being energized and heated, and uses certain technical means to accelerate the electron. 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.
LED is the abbreviation of the LED. The main component of the LED lamp is a semiconductor that converts electrical energy into light energy. It is connected to the circuit board with silver wire or gold wire, and the surrounding user is sealed with epoxy resin to protect the whole body in the protective case.
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 a 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.
