What is the difference between fluorescent and incandescent lamps? Difference Between Incandescent a

No one got it right!

Incandescent lamp. Also known as the light bulb, it works by passing an electric current through a filament (tungsten filament, with a melting point of more than 3,000 degrees Celsius.

When heat is generated, the spiral filament continuously gathers heat, so that the temperature of the filament reaches more than 2000 degrees Celsius, and when the filament is in an incandescent state, it emits light like red-hot iron can shine. The higher the temperature of the filament, the brighter the light emitted. Therefore, it is called incandescent lamp.

When an incandescent lamp emits light, a large amount of electrical energy is converted into heat, and only a very small fraction (probably less than 1%, not calculated) can be converted into useful light energy.

Fluorescent lamps are also known as fluorescent lamps.

How it works: The fluorescent tube is simply a closed gas discharge tube. The main gas in the tube is argon (argon) gas (including neon neon or krypton), and the pressure is about the atmosphere. Also contains a few drops of mercury.

Formation of trace amounts of mercury vapor. The mercury atom is about one thousandth of the atom of all gases.

The fluorescent lamp, commonly known as the "electric rod", is a slender cylindrical white opaque glass tube, (the white substance in the lamp tube is the phosphor that causes light, so it is also called a fluorescent lamp), and there are two thin legs at each end, because the light illuminated by the sun will not cause the object to change color, so it is called a fluorescent lamp.

Incandescent lamp, commonly known as "bulb", is generally pear-shaped transparent glass, and the light is the filament (tungsten filament) inside, and the color of the light irradiated is similar to white but yellowish, and the brightness is not good, and the heat is hot, and the power consumption is also great. It has been gradually replaced by fluorescent energy-saving lamps.

Fluorescent energy-saving lamps, like fluorescent lamps, the same principle and effect of luminous lamps, the luminous tube is generally a "U" or spiral shape of white opaque glass. But it is not as troublesome as the installation of fluorescent lamps, which can directly replace ordinary light bulbs (incandescent lamps), although the ** is a little higher, but the light effect is very good, and it is also energy-saving, and the brightness of a 16-watt energy-saving lamp is equivalent to a 60-watt bulb.

The landlord still doesn't understand the hardware and electrical material store, what you say, others will give you something, don't you understand?

Difference Between Incandescent and LED Lights

1. The principle of luminescence is different.

The working principle of incandescent lamp is that when the current passes through the filament, it generates heat, and the spiral filament continuously gathers the heat, so that the temperature of the filament reaches more than 2000 degrees Celsius.

LED lamp, also known as light-emitting diode, is a solid-state semiconductor device that can directly convert electricity into light. The heart of an LED is a semiconductor wafer with one end attached to a bracket, one end is the negative electrode, and the other end is connected to the positive electrode of the power supply, so that the entire wafer is encapsulated by epoxy resin.

2. The life span is different.

Incandescent lamps, fluorescent lamps, and tungsten halogen lamps use electronic light field to emit light, and the filament is easy to burn, with thermal deposition, light attenuation, and short life; The LED lamp is small in size, light in weight, and encapsulated in epoxy resin, which can withstand high-strength mechanical impact and vibration, is not easy to break, and has an average life of 100,000 hours.

3. The luminous efficiency is not the same.

Incandescent lamps use heat as a prerequisite for emitting light, and most of the energy is wasted in the form of heat, so the efficiency is very low, generally below 15 lm w, and has not changed much in a hundred years. LEDs, on the other hand, were only available when they were first born, and now they have reached 200 LM W, an increase of more than 2,000 times over the decades. Ichigoshi has become the most efficient light source to date.

The principle of luminescence is different, the heat radiation produced is different, and the light emitted is different.

1.The principle of luminescence is different.

Incandescent lamp. Also known as a light bulb, it works by generating heat when an electric current is passed through the filament. LED lights.

Also known as light-emitting diodes.

It is a solid-state semiconductor device that can directly convert electricity into light.

2.The heat radiation produced is different.

The heat of an incandescent lamp can be felt in a short period of time, and the more power there is, the more heat there is, and the electrical energy is converted partly into light and partly heat. LED electrical energy converts light energy, produces very little heat radiation, most of the ability is directly converted into light energy, and the general lamp power is low, coupled with the heat dissipation structure, compared with incandescent lamps, the thermal radiation of LED cold light source is better.

3.The lights emitted are different.

The light emitted by an incandescent lamp is panchromatic staring light, but the composition ratio of each color is determined by the luminescent substance and temperature.

Fluorescent lamp = fluorescent lamp.

Differences: 1. Different properties: incandescent lamps are electric light sources that heat the filament to an incandescent state and use thermal radiation to emit visible light.

Energy-saving lamps are lighting devices that combine fluorescent lamps and ballasts (ballasts) into a single unit. Fluorescent lamps use low-pressure mercury vapor to release ultraviolet light after being energized, so that phosphors emit visible light.

2. The service life is different: the service life of incandescent lamps is much shorter than that of energy-saving lamps, usually the service life of incandescent lamps is 1000 hours, while the service life of energy-saving lamps is more than 6000 hours.

3. Different light efficiency: in the case of the same illumination, the energy consumption of energy-saving lamps is smaller, and the light efficiency of three-color energy-saving lamps is generally 40-80lm w, while the light efficiency of incandescent lamps is 10lm w. Fluorescent lamps commonly have a nominal power of 4W and 6W.

Incandescent lamps are heated to a certain temperature (about 2600 degrees) by tungsten filament (energized) before emitting light.

Fluorescent lamps emit ultraviolet light by bombarding mercury atoms with electrons, and ultraviolet light excites phosphors.

Energy-saving lamps and fluorescent lamps are all fluorescent lamps. Among them, the phosphor used in energy-saving lamps is "rare earth tricolor", and the phosphor used in ordinary fluorescent lamps is "halogen powder".

Incandescent lamps are filaments for luminescent materials, energy-saving lamps, fluorescent lamps, fluorescent lamps, and their collective names are fluorescent lamps, which are activated by electron emission to emit mercury light

1. The color path of light is different. Incandescent lamps emit light through tungsten filaments, and the color is mainly warm yellow, which is mostly the color of traditional lamps and lanterns, while fluorescent lamps are emitted through phosphors, and the color is mainly cold white.

2. The eye protection effect is different. The incandescent lamp has a soft color and low brightness, which does not pierce the eyes and has a certain protective effect on eyesight, while the fluorescent lamp is more dazzling, and the bias is blue and white, which is not good for the eyes.

3. The life span is different. The incandescent lamp has a limit on the number of switches, and the life span is only about 1000 hours, the production process is simple, and the fluorescent lamp will not be affected by repeated switching, and the life is longer.

1. The difference between incandescent lamps and fluorescent lamps.

Difference Between Incandescent and Fluorescent Lamps1. Different lighting methods and colors.

Incandescent lamps mainly emit light through tungsten filaments, and like ordinary bulbs, spotlights and iodine-tungsten lamps are emitted through tungsten filaments, which belong to traditional lamps and lanterns with warm yellow light. Fluorescent lamps emit light by emitting light, so they are also called fluorescent lamps. Different phosphors will result in different light colors, mainly cold light and warm light.

Difference Between Incandescent and Fluorescent Lamps2. Different eye protection effects.

The light of incandescent lamps is yellow, which is a soft and stable light, with low brightness, red and yellow hues, which will be closer to the effect of sunlight, so it is also good for vision health. The light of the fluorescent lamp is mainly white and blue, which is not only dazzling and flickering, but also different from natural light, which is not good for the eyes, and it is easy to cause eye fatigue and soreness when reading and using.

Difference Between Incandescent and Fluorescent Lamps.

Different value for money.

Incandescent lamps belong to thermal radiation, so they produce a lot of heat and consume a lot of energy, and their service life is generally only about 1000 hours. However, it is cheap and does not contain mercury pollution. Not only is the manufacturing process simple, but also the raw materials are relatively ordinary.

When in use, it can emit light immediately after opening, and repeated opening and closing will not have much effect, and it is cost-effective.

Although fluorescent lamps produce less heat and consume less energy, and their service life is four or five times that of incandescent lamps, they are expensive and have mercury pollution. Not only is the manufacturing process relatively complex and materials scarce, but the design brightness will also be delayed for a period of time when it is turned on. If it is switched on and off repeatedly, it is easy to damage the service life, and it is not cost-effective.

2. What are their advantages and disadvantages?

1.Advantages and disadvantages of incandescent lamps.

The incandescent lamp has good color rendering and small color distortion, which is suitable for lighting in occasions with good color discrimination conditions. Extremely low color temperature, comfortable lighting, suitable for bedroom, living room and other lighting. It has good start-up performance, can quickly reach the rated value, is very helpful for emergency lighting, and has a beautiful appearance, which can be used for decorative and artistic lighting.

The key is small size and low cost. However, its luminous efficiency is low, the life is short, the power consumption is high, and the electricity cost is relatively high.

2.Advantages and disadvantages of fluorescent lights.

Fluorescent lamps mainly have the advantages of energy saving, long life, good applicability, changeable appearance, and bright colors. It is expensive, and there is a big gap between the actual light effect and the harmony theory.
