Different from ordinary fluorescent lamps, LED fluorescent lamps are the same as traditional fluorescent lamps in appearance size and caliber, with lengths of 60cm, 120cm and 150cm respectively.
Its power is 10W, 16W and 20W respectively, while the actual power consumption of 20W traditional fluorescent lamp (inductive ballast) is about 53W, and that of 40W traditional fluorescent lamp (inductive ballast) is about 68W. In other words, their seats are the same, which makes it easier to change the program.
So what are the specific advantages of LED fluorescent lamps? There are mainly the following points
Noisy and warm, no noise.
LED lights will not produce noise, and the place where fine electronic instruments are used is the best choice. Suitable for libraries, offices and other places.
Mild light, eye care.
Traditional fluorescent lamps use alternating current, so they generate 100- 120 strobes per second. LED lights directly convert alternating current into direct current, which will not flicker and protect eyes.
No ultraviolet rays, no mosquitoes.
LED lamps do not generate ultraviolet rays, so there are not many mosquitoes coiled around the lamp source like traditional lamps. The room will become cleaner and cleaner.
Environmental protection lamps and lanterns, protect the earth
Traditional fluorescent lamps contain a lot of mercury vapor, which will evaporate into the atmosphere if it breaks down. The LED fluorescent lamp basically does not use mercury, and LED products do not contain lead, which plays a role in maintaining the environment. LED fluorescent lamps are recognized as green lighting in 2 1 century.
Efficient conversion, fever reduction
Traditional lamps will generate a lot of heat energy, while LED lamps will convert all electric energy into light energy without wasting energy. And there will be no fading of documents and clothes.
What's the difference between incandescent lamp and LED lamp?
LED lamp is an energy-saving lamp and an advanced product of incandescent lamp.
Compared with incandescent lamps, LED lamps have the characteristics of energy saving, long life and double eye protection. Now the country has been vigorously promoting the use of LED lamps, especially the * * * street lamp reconstruction project is the first LED street lamp.
If you want to buy LED lights, I suggest you have a look at the LED lights of Ramon Ramon series. First of all, this series of LED lamps has a long service life. Assuming that it is used for 6 hours every day, it can be used for about 20 years without damage, far exceeding the service life of most incandescent lamps.
Ramon Ramon's LED has passed the test of the world's top eye hospitals, which not only does not contain ultraviolet rays, infrared rays and electromagnetic waves, but also does not generate heat when used in summer, which doubles the protection of eyes and makes the body feel comfortable. Now it is also exhibited as a treasure in Munich, Germany, the largest museum of modern art in the world. It is indeed a big brand of LED lamps, which is better than incandescent lamps in any aspect.
What's the difference between led lights and energy-saving lamps?
People use led and other energy-saving lamps to drink more, because these lamps are beautiful in appearance and not bad in performance at all, and can also play the role of lighting to drive away darkness. The essential difference between LED and other energy-saving lamps is an armchair strategist. Then I'll pick up Hu Search. What's the difference between led lights and energy-saving lamps? Advantages and disadvantages of energy-saving lamps?
What's the difference between led lights and energy-saving lamps?
A: The characteristics of led.
1. voltage: LED uses low-voltage power supply, and the power supply voltage is between 6-24V, which varies according to different products, so it is safer than using high-voltage power supply and is suitable for public places.
2. Efficiency: Compared with incandescent lamps with the same light efficiency, the energy consumption is reduced by 80%.
3. Applicability: Very small, each unit LED chip is 3-5mm square, so it can be made into devices with various shapes and is suitable for changing environments.
4. Stability: 654.38+100000 hours, and light attenuation is 50% of the initial value.
5. Response time: The response time of incandescent lamp is millisecond, and that of LED lamp is nanosecond.
6. Environmental pollution: no harmful metal mercury.
B,: brightness
Candlelight = 1 lumen/root
Incandescent lamp = 1 1- 15 lumens/watt
Energy-saving lamp =40-60 lumens/watt
Led lamp =80- 120 lumens/watt
1W LED=3W CFL (energy saving lamp) = 15W incandescent lamp.
3W LED=8W CFL (energy saving lamp) =25W incandescent lamp
4wled = 1 1CFL (energy-saving lamp) =40W incandescent lamp.
8W LED= 15W CFL (energy saving lamp) =75W incandescent lamp.
12W LED=20W CFL (energy saving lamp) = 100W incandescent lamp.
15WLED=25W CFL (energy saving lamp) = 125W incandescent lamp
Advantages and disadvantages of energy-saving lamps?
Advantages of energy-saving lamps:
1, energy saving and pollution-free means environmental protection. Driven by DC, the ultra-low power electro-optical power conversion is close to 100%, and the equivalent light efficiency is more than 80% less than that of the traditional light source.
2. Generally speaking, under the same wattage, energy-saving lamps save 80% more energy than incandescent lamps, prolong their average life by 8 times, and radiate only 20%.
3. Under the premise of achieving the same light output, it only needs to consume the power consumption of ordinary incandescent lamps 1/5 to 1/4, which saves a lot of lighting energy and expenses, so it is called energy-saving lamp.
Disadvantages of energy-saving lamps:
1, energy-saving lamps are bright line spectrum, so the usual energy-saving lamps are purple light, and things will seriously change color under energy-saving lamps. Blue will turn purple, and red and yellow will look brighter. Therefore, energy-saving lamps should not be used in color matching workplaces.
2. Scientists have come to a preliminary conclusion after long-term investigation and study: the radiation of energy-saving lamps may cause danger to personal health and even cause cancer.
3. Mercury pollution exists in energy-saving lamps during production and after abandonment. At present, western countries attach great importance to mercury pollution. People in China are increasingly aware of the dangers of mercury pollution.
4. Because energy-saving lamps are glass products, they are easy to be broken, difficult to transport and difficult to install.
What's the difference between led lights and energy-saving lamps? Advantages and disadvantages of energy-saving lamps? The length of time that lamps want to be used mainly depends on the maintenance during use, that is, people frequently press the switching power supply of lamps, which will affect the service life of lamps. Especially for the wick, it is a great harm. It may even lead to the result that the wick is not bright.
The difference between incandescent lamp, energy-saving lamp and LED lamp
Hello! First of all, incandescent lamps are also called light bulbs. Its working principle is that when current passes through the filament (tungsten filament, melting point is more than 3000 degrees Celsius), it generates heat. The spiral filament continuously accumulates heat, making the temperature of the filament reach more than 2000 degrees Celsius. When the filament is incandescent, it will glow, just as red-hot iron can glow.
Then energy-saving lamps are also called energy-saving bulbs, electronic bulbs, compact fluorescent lamps and integrated fluorescent lamps, which refer to lighting equipment that combines fluorescent lamps and ballasts.
Finally, LED lamp, also called light emitting diode, is a solid semiconductor device, which can directly convert electricity into light. The heart of LED is a semiconductor chip, one end of which is attached to the bracket, one end is the negative electrode, and the other end is connected to the positive electrode of power supply, so that the whole chip is encapsulated by epoxy resin.
Generally speaking, there are advances in lighting products, incandescent lamps.
Hope to adopt.
The difference between halogen lamp and incandescent lamp, energy-saving lamp and LED lamp is 50W, 100W,
From the light-emitting principle, the difference between the above lamps and LED lamps lies in incandescent lamps, energy-saving lamps and so on. They all convert electric energy into heat energy and then excite it into light energy, which wastes most of the energy. LED directly converts electric energy into light energy, saving most of the energy. In addition, the effect can be distinguished from two aspects: 1. The luminous flux (lumen) of halogen lamps is generally 20LM/W, that of energy-saving lamps is generally 50-60lm/w, and that of LEDs is generally 80- 1 10LM/W, that is, the total amount of light generated by each W light source is quite different, so it can reflect the energy-saving effect. 2. Luminous efficiency (luminous efficiency) The luminous efficiency of halogen lamps is generally around 30%, energy-saving lamps are generally around 60%, and LED luminous efficiency can reach 90%. This is also a major factor in energy conservation. It can be seen from the above points that the luminous flux of LED is more than 2 times that of energy-saving lamps, more than 5 times that of incandescent lamps, and 50WLED is equivalent to more than 250W lamps/halogen lamps of 1 10W energy-saving lamps, and so on. I hope to discuss with friends from all walks of life.
What are the advantages, disadvantages and differences of incandescent lamp, fluorescent lamp, energy-saving lamp and LED lamp?
Incandescent lamp, a lamp that uses resistance to heat filaments (usually tungsten filaments in modern times) into incandescent light. Although incandescent lamp has low light efficiency, it has good light color and light collection performance, and it is the largest output and the most widely used electric light source. Among all the lighting lamps that use electricity, incandescent lamps have the lowest efficiency. Only about 2% of the electricity it consumes can be converted into light energy, and the rest is lost in the form of heat energy.
Fluorescent lamps are divided into traditional fluorescent lamps and electrodeless fluorescent lamps. The traditional fluorescent lamp, that is, low-pressure mercury lamp, uses low-pressure mercury vapor to radiate ultraviolet rays in the discharge process, so that the phosphor emits visible light, so it belongs to low-pressure arc discharge light source. An electrodeless fluorescent lamp is an electrodeless lamp, which cancels the filament and electrode of the traditional fluorescent lamp and excites mercury atoms from the original state to the excited state by using the principle of electromagnetic coupling. Its luminous principle is similar to that of traditional fluorescent lamps, and it has the advantages of long life, high luminous efficiency and good color rendering. Because most of the electric energy consumed by fluorescent lamps is used to generate ultraviolet rays, the luminous efficiency of fluorescent lamps is much higher than that of incandescent lamps and tungsten halogen lamps, and they belong to energy-saving electric light sources.
Energy-saving lamps, also known as energy-saving bulbs, electronic bulbs, compact fluorescent lamps and integrated fluorescent lamps, refer to lighting equipment that combines fluorescent lamps and ballasts. On the premise of achieving the same light output, this light source only needs to consume the power consumption of ordinary incandescent lamps 1/5 to 1/4, which can save a lot of lighting electricity and expenses, so it is called energy-saving lamp. Each waste energy-saving lamp can pollute 180 tons of water and five or six acres of land.
LED lamp, light emitting diode, is a solid semiconductor device that can convert electric energy into visible light, and it can directly convert electricity into light. Advantages: high quality, durability, energy saving, wide adjustment range of projection angle, and the brightness of 15W is equivalent to that of ordinary 40W fluorescent lamp. Resistant to high temperature, moisture, water and leakage. But the price is more expensive, and poor heat dissipation will greatly shorten the life.
What are the advantages, disadvantages and differences of incandescent lamp, fluorescent lamp, energy-saving lamp and LED lamp?
In daily life, we often come into contact with the concepts of incandescent lamp, fluorescent lamp, energy-saving lamp and LED lamp. But do you really know the difference between these lights? Do you know how they work? Do you know their advantages and disadvantages? Let's popularize the knowledge of these lamps.
filament lamp
Incandescent lamps are also called light bulbs. Its working principle is that when current passes through the filament (tungsten filament with melting point over 3000 degrees Celsius), heat is generated. The spiral filament continuously accumulates heat, making the filament temperature reach more than 2000 degrees Celsius. When the filament is incandescent, it will glow, just as red-hot iron can glow. The higher the temperature of the filament, the brighter the light it emits. So it's called incandescent lamp. When incandescent lamps emit light, a lot of electric energy will be converted into heat energy, and only a very small part (maybe less than 1%, not counted) can be converted into useful light energy.
The light emitted by incandescent lamps is full color light, but the proportion of each color light is determined by the luminescent substance (tungsten) and temperature. The imbalance of proportion leads to the color deviation of light, so the color of the object is not true enough under incandescent lamp.
The life of an incandescent lamp is related to the temperature of the filament, because the higher the temperature, the easier it is for the filament to sublimate. The process of blackening at both ends of fluorescent lamp is that the tungsten wire sublimates directly into tungsten wire gas, which condenses on the lamp wall at a lower temperature to blacken. When the tungsten wire sublimes to be thinner, it is easy to burn out after being electrified, thus ending the life of the lamp. So the greater the power of incandescent lamps.
fluorescent lamp
Fluorescent lamp is also called fluorescent lamp, and its working principle: fluorescent tube is simply a closed gas discharge tube. The main gas in the tube is argon (including neon or krypton), and the pressure is about 0.3% of atmospheric pressure. In addition, it also contains a few drops of trace mercury vapor that forms silver. Mercury atoms account for about one thousandth of all gas atoms.
Fluorescent tubes are mercury atoms leaning against the tubes, which release ultraviolet light (the main wavelength is 2537 A =2537* 10- 10m) when gas is discharged. About 60% of the consumed electric energy can be converted into ultraviolet light. Other energy is converted into heat energy.
Fluorescent lamps absorb ultraviolet light from fluorescent substances on the inner surface of the lamp tube and release visible light. Different fluorescent substances will emit different visible light. Generally, the efficiency of converting ultraviolet light into visible light is about 40%. Therefore, the efficiency of fluorescent lamps is about 60% * 40% = 24%-about twice that of tungsten lamp with the same power.
Energy-saving lamp
Energy-saving lamps, also known as compact fluorescent lamps (CFL lamps for short in foreign countries), have the advantages of high luminous efficiency (5 times that of ordinary light bulbs), obvious energy-saving effect, long service life (8 times that of ordinary light bulbs), small size and convenient use. Its working principle is basically the same as that of fluorescent lamp.
In addition to white light (cold light), there are * * * (warm light) energy-saving lamps. Generally speaking, under the same wattage, energy-saving lamps save 80% more energy than incandescent lamps, prolong their average life by 8 times, and radiate only 20%. Under non-strict conditions, a 5-watt energy-saving lamp can be regarded as a 25-watt incandescent lamp, a 40-watt 7-watt energy-saving lamp and a 60-watt 9-watt energy-saving lamp.
Led light
LED (Light Emitting Diode), also known as light emitting diode, is a solid-state semiconductor device, which can directly convert electricity into light. The heart of LED is a semiconductor chip, one end of which is attached to the bracket, one end is the negative electrode, and the other end is connected to the positive electrode of power supply, so that the whole chip is encapsulated by epoxy resin. The semiconductor wafer consists of three parts, one is a P-type semiconductor, in which holes are dominant, and the other is an N-type semiconductor, which is mainly electrons, with a quantum well of 1 to 5 cycles in the middle. When the current acts on this chip through the wire, electrons and holes will be pushed into the quantum well, where they will recombine with the holes and then emit energy in the form of photons, which is the principle of LED light emission.

What's the difference between LED lights and energy-saving lamps?
LED lamp, light emitting diode is called led for short.
Diodes made of compounds containing gallium (Ga), arsenic (As), phosphorus (P) and nitrogen (N) can emit visible light when electrons and holes recombine, so they can be used to make light-emitting diodes. Used as an indicator light in circuits and instruments, or as a text or digital display.
Gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light and gallium nitride diodes emit blue light. Because of its chemical properties, it can be divided into organic light-emitting diode and inorganic light-emitting diode LED.
Energy-saving lamps, also known as energy-saving bulbs, electronic bulbs, compact fluorescent lamps and integrated fluorescent lamps, refer to lighting equipment that combines fluorescent lamps and ballasts. In 2008, the state started the "green lighting" project, and urban and rural residents and enterprises enjoyed a certain percentage of subsidies for using the energy-saving lamps of the winning enterprises.
The promotion of energy-saving lamps is of great significance, however, the harm of waste energy-saving lamps to the environment has also attracted people's attention. By the end of 20 12 and 10, hundreds of millions of energy-saving lamps have been scrapped in the energy-saving promotion project, each of which can pollute 180 tons of water and soil. The treatment and recycling of waste energy-saving lamps have attracted people's attention.
Nevertheless, people's demand for energy-saving lamps is still growing, especially in the coming 20 14 years. .
