Advantages of energy-saving lamps:
1. LED energy-saving lamps are highly efficient and energy-saving: lighting in modern society is an indispensable tool in people's lives, so energy consumption is also very.
Large, heavy use of LED lights, will save a lot of energy. Comparison of several lamps that consume the same 1 kilowatt-hour of electricity while emitting the same brightness.
A. The LED light only needs 3W and can be used for 333 hours.
b. Ordinary incandescent lamps need 60W to work, but they can only be used for 17 hours.
c. Ordinary energy-saving lamps need 10W to achieve the same brightness, and 1 kWh of electricity can be used for 100 hours.
As can be seen from this, LED lamps can save at least 3 times more energy than ordinary energy-saving lamps.
2. LED energy-saving lamps have a long service life: LED lamps emit light through semiconductor chips, without glass bubbles, not afraid of vibration, and not easy to break.
The service life can reach 50,000 hours. Compared with the production of ordinary light bulbs (1000 hours of use), it is 50 times longer than its use time; With the general energy energy-saving lamp (make.
8,000 hours) is more than 6 times longer. It's the obvious super boss.
3. LED energy-saving lamps are green and environmentally friendly, and they are healthy to use: LED lamps do not contain harmful elements such as mercury and xenon, and will not produce electromagnetic radiation and harmful emissions.
Line. a. Ordinary lamps contain elements such as mercury and lead, and harmful radiation such as external and infrared rays are generated when the power supply passes;
b. The electronic ballasts in energy-saving lamps will produce electromagnetic interference, which is also not conducive to health.
4. High light conversion rate: 90% of the electrical energy of LED lamps is converted into light energy, while only 20% of ordinary bulbs are converted into light energy.
5. LED energy-saving lamps are safe and more widely used. LED lamps require less voltage, less current, and less heat, and can be directly used for sunlight supply.
Electricity, field lighting and other remote places, no geographical restrictions.
6. Protect eyesight, no jitter of the light source.
LED energy-saving lamps have been applied very early, such as the indicator lights on the computer and the indicator lights on the TV, all of which belong to the LED lights, but they should be.
It is still a matter of the last few years to use it for lighting. With the development of science and technology, the cost of making LED lights has been greatly reduced, when it is low enough to accept the capacity.
, began to be applied on a large scale, so there are many advantages of LED energy-saving lamps, but there is only one disadvantage, that is, the cost is relatively high, but with.
With the advancement of science and technology and a large number of applications, cost is not a problem. Flashlights, electric lights, and car lights are also being used in large quantities.
LED lights up. Ningbo decoration network to give you an analysis of the advantages and disadvantages of LED, I hope you have something to gain after reading.
The working principle of LED energy-saving lamps is: using high-brightness white light-emitting diodes as the light source, the cold light source used, does not produce heat, and is more economical.
Electricity. The light source can realize seven color changes of LED through the built-in controller of the microcomputer, and the light color is soft, bright and colorful.
———1. The energy-saving lamp comes with an electronic ballast, which is the circuit board, after starting, the filament at the two poles in the lamp emits electrons to quickly hit the argon atom to produce an inelastic collision, and the argon atom obtains energy after the collision and hits the mercury atom, and the mercury atom jumps to produce ionization after absorbing energy, emitting ultraviolet rays, and ultraviolet rays excite rare earth trichromatic phosphors to shine. No need for ballast jumping. >>>More
There is a detailed explanation in the physics book for the third year of junior high school.
LED fluorescent lamps and street lamps are common lighting equipment in the field of modern lighting, and their quality and safety are crucial for the user's experience and life safety. In order to ensure the quality and safety of products, many countries and regions have certification requirements for LED fluorescent lamps and street lights. >>>More
Professional photographic lights and ordinary energy-saving lamps can not be compared, professional photographic lights are much better than ordinary energy-saving lamps in terms of strobe, color rendering, etc. >>>More
