The difference between fluorescent lamps and energy-saving lamps

Lamps are indispensable in today's life. In the past, they used to be sunsets and sunsets. After the light, they can work at night. Nowadays, there are many kinds of lamps, fluorescent lamps, energy-saving lamps, incandescent lamps. Wait, let's talk about the first two, then what is the difference between fluorescent lamps and energy-saving lamps? What are the characteristics of fluorescent lamps and energy-saving lamps?

The difference between fluorescent lamps and energy-saving lamps:

1, the ratio of life

The average life of the fluorescent lamp is 1000 hours. When the fluorescent lamp is used for a long time, the glass bulb will turn black, and after a while, it will be blown because the filament used in the fluorescent lamp is made of tungsten wire. After the power is turned on, the temperature inside the bulb is as high as 2000 degrees. The long-term high temperature causes the tungsten atoms on the surface of the tungsten wire to continuously evaporate and diffuse like water vapor, and then deposit layer by layer on the inner surface of the glass bulb to make the glass bulb. Slowly blackened and increasingly opaque. The evaporation of tungsten also makes the tungsten wire thinner and finer, and finally blows. The higher the operating temperature of the filament, the faster the evaporation of tungsten and the shorter the service life of the fluorescent lamp. The life of energy-saving lamps is as long as 8,000 hours, and the luminous efficiency is 6 to 8 times that of ordinary light bulbs.

2, the ratio of prices

The market price of fluorescent lamps is 25W to 100W, the price is 2 yuan to 3 yuan, and the price of energy-saving lamps is from 8 yuan to tens of yuan. The price is several times that of fluorescent lamps, which means that 15 bulbs are installed according to one family. To calculate, the fluorescent lamp is 3 × 15 = 45 yuan, and the energy-saving lamp is 15 × 15 = 225 yuan, but from the practical point of view, a household energy-saving lamp is 864 yuan - 225 yuan = 639 yuan a year, so It is more economical to save energy.

3, the ratio of advantages and disadvantages

Although the luminous efficacy of the fluorescent lamp is low, the light color and light collecting performance are good, the installation and use are easy, the device can be started immediately, and the cost is low. It is the largest and most widely used electric light source, and for more than 100 years, people have kept on The research, the continuous improvement of filament materials, filament structure, filling gas, the luminous efficiency of fluorescent lamps is also improving with the times.

Energy-saving lamps, which can consume 1/5 to 1/4 of the electricity consumption of ordinary incandescent lamps on the premise of achieving the same light energy output, thereby saving a large amount of lighting power and cost. Compared with ordinary fluorescent lamps, 70-80% energy saving, low-voltage fast start, no stroboscopic flash; using pure three-primary fluorescent lamp to make the lighting objects bright and fresh; novel design, with a number of patented technologies, the bracket is made of aluminum alloy, small and beautiful, never rust, environmental protection, flame retardant.

Fluorescent lamp and energy saving lamp features:

Fluorescent lamp features

The fluorescent lamp is also called a fluorescent lamp. Its working principle: the fluorescent tube is simply a closed gas discharge tube. The main gas in the tube is argon gas (including 氖neon or 氪krypton) and the gas pressure is about 0.3% of the atmosphere. Also contains a few drops of mercury - forming a trace of mercury vapor. Mercury atoms account for about a thousandth of all gas atoms.

The fluorescent lamp emits visible light by absorbing ultraviolet light from the fluorescent material on the inner surface of the tube. Different phosphors emit different visible light. Generally, the efficiency of converting ultraviolet light into visible light is about 40%. Therefore, the efficiency of the fluorescent lamp is about 60% x 40% = 24% - about twice that of the same power tungsten wire.

The disadvantage of fluorescent lamps is that they are polluted by the production process and after being scrapped, mainly mercury pollution, and not environmentally friendly. As the process improves, the conversion to amalgam mercury is gradually reduced.

Energy-saving lamp features

The energy-saving lamp is also called a compact fluorescent lamp (referred to as CFL lamp in foreign countries). It has high luminous efficiency (5 times that of an ordinary light bulb), obvious energy-saving effect, long life (eight times that of an ordinary light bulb), small size and convenient use.

In addition to white (cold light), energy-saving lamps now have yellow (warm light). Generally, under the same wattage, an energy-saving lamp is 80% more energy efficient than an incandescent lamp, with an average life expectancy of 8 times and a thermal radiation of only 20%. In a non-strict case, a 5-watt energy-saving lamp can be considered as an incandescent lamp equal to 25 watts, a 7-watt energy-saving lamp is about 40 watts, and a 9-watt is about 60 watts.

The electromagnetic radiation of energy-saving lamps also comes from the ionization reaction between electrons and mercury gas. At the same time, energy-saving lamps need to add rare earth phosphors. Since the rare earth phosphors themselves are radioactive, energy-saving lamps also generate ionizing radiation (ie, radiation nuclear radiation). The uncertainty of electromagnetic radiation on human body damage, and the excessive radiation radiation to the human body is more worthy of attention. In addition, due to the limitation of the working principle of energy-saving lamps, mercury in the lamps is inevitably a major source of pollution. An ordinary energy-saving lamp contains about 5 mg of mercury, which is only enough to be covered with a ballpoint pen tip, but it may cause 1800 tons of water to be contaminated after it penetrates into the ground.

The difference between the fluorescent lamp and the energy-saving lamp and the knowledge of the characteristics of the fluorescent lamp and the energy-saving lamp are mentioned here first. I believe that everyone should have more knowledge after reading it. The content is for your reference only. I hope I can have something for everyone. help.
