What is the energy saving rate of a single lamp?

This is actually a very general question. As far as the energy saving of lamps and lanterns is concerned, the first is the energy saving of the light source, that is, in the case of achieving the same lighting effect, the use of more energy-saving light sources, such as the use of fluorescent lamps instead of incandescent lamps or halogen lamps, of course, there will be some sacrifices in the lighting effect, such as the color rendering is relatively poor, but the system light efficiency may be increased from 20 30lm w to 80 90lm w. Some people will also mention LEDs, in fact, the system light efficiency is currently at most 80 90W lm, which is not advantageous compared to fluorescent lights.

The advantage of LED is that it has a long service life and small light attenuation, but the environmental requirements for its use are also relatively high, and the system stability is not good. At present, the highest light efficiency is the sodium lamp, which is our most commonly used street lamp, which can reach 120 160lm w, but its disadvantage is also very obvious, that is, the color rendering is too poor. In short, the selection of lamps and lanterns needs to be selected according to the specific use requirements.

The second is the problem of control, such as the so-called intelligent control, or sound and light control, touch switch, for some places such as stairwells are very useful, even if some investment is added is very cost-effective. However, for the workplace, the relevant intelligent control may bring some unnecessary trouble, because the user may not have a special understanding of the system, or the designer takes the system for granted and does not really understand the user's needs. In this case, the use of work lights is actually a better way, such as desk design work lamps, only used when someone is working, and for example, in the equipment or area with higher illuminance requirements to set up low-level lighting, instead of the entire workshop space lighting design to a specific area of illumination requirements, so that the energy-saving effect is particularly prominent.

In addition, I personally feel that good energy-saving design is not as good as good energy-saving management or habits, such as turning off the lights when people walk is a good management measure and habit.

In terms of the above, it is actually meaningless to calculate the energy saving rate of a single lamp.

If the use of voice control or touch induction control, the energy saving rate of a single lamp can be greatly greater than 35%, to a 8 watt lighting fixture to calculate, every night is not controlled, has been on, about 8 hours of calculation, power consumption about, if the use of intelligent control, about the duration of each lighting is 1 minute, a night has 10 times to be lit, then the total power consumption only, then the energy saving rate will reach more than 98%. Of course, the use of intelligent control increases the investment, so it is necessary to carefully conduct a technical and economic analysis and comparison to see how much time it takes for the increased investment to be offset by the saved electricity bills, and whether it is cost-effective.

With intelligent control, the energy-saving rate of a single lamp can reach 35%.

Under the premise of the same lighting effect, the power consumption of energy-saving lamps is 1 5 of ordinary incandescent lamps, but the service life is 6 times that of ordinary incandescent lamps, and the service life of qualified energy-saving lamps is generally more than 6000 hours. For example, a 13-watt energy-saving lamp is equivalent to a 60-watt incandescent lamp, so the energy-saving lamp can save 75% of electricity.

The size of the energy-saving lamp is similar to that of the incandescent lamp, and the interface with the lamp holder is also the same as that of the incandescent lamp, so the incandescent lamp can be replaced directly. The official name of the energy-saving lamp is the rare earth trichromatic compact fluorescent lamp, which was born in the 70s of the 20th century in the Netherlands by Philips.

Whether energy-saving lamps or bulbs are burned, energy-saving lamps must be much more energy-saving than ordinary bulbs, if you want to energy-saving lamps have a long life, then you must turn on energy-saving lamps for a long time each time, if you don't turn on enough for a minute or two and turn off, back to the length of the life of energy-saving lamps!

High-quality energy-saving lamps are the same as ordinary incandescent lamps.

Ratio, under the same illumination situation, it is 5 times the efficiency of incandescent lamp, 8 times the life of incandescent lamp, and the power saving rate is as high as 80%.

In other words, 20W of energy-saving lamps is equivalent to 100W of ordinary lamps

LED lights are more energy-efficient, and the specific amount of electricity used depends on the power of the purchased LED lights.

In the sphere of the 3m photometric integrating sphere, the staff connected the incandescent lamp to the lamp holder with a voltage of 220 volts, turned off the sphere, waited for 5 minutes, and measured the current to measure the actual power of the bulb. After testing, it is concluded that the current of the incandescent lamp is ampere, and the measured power is watts.

Similarly, if you connect the energy-saving lamp to a 220-volt lampholder, you need to wait for the energy-saving lamp to stabilize before testing because the energy-saving lamp has a light stabilization time of 10 minutes. After testing, it is concluded that the current of the energy-saving lamp is ampere, and the measured power is watts. Connect the LED lamp to the lamp holder, close the sphere, and measure the LED lamp current to be ampere, and the measured power to be watts.

The energy saving of LED lamps mainly depends on the initial light effect, the larger the initial light effect, the more energy-saving. Judging from the detection situation, the initial light efficiency of LED lamps is significantly higher than that of incandescent lamps and energy-saving lamps, and it is indeed more energy-saving. In addition to being more energy-efficient, LED lamps are also safer than incandescent lamps and energy-saving lamps.

This is because the power consumption of a single LED is very low, the requirements for conductive lines are not high, and there are fewer short-circuit faults caused by line aging.

Not necessarily, different bai model du

The luminaires have different light effects. Energy-saving lamps.

Generally refers to fluorescent lamps and lanterns. LED lamps can use at least half of the electricity compared to energy-saving lamps.

In the case of the same lighting effect, the power consumption of LED lamps is about one-tenth of that of incandescent lamps, one-half of that of fluorescent tubes, and a fluorescent lamp with the same effect is more than 40 watts, while the power of each LED is only 18 watts.

It is inaccurate to say that LED lamps save more electricity than ordinary double-U energy-saving lamps. bai

It is not that the lamp saves power, and the power consumption is the same under the same power. dao

The reason why LED lights are power-saving is because the brightness of 3W LED lamps is equivalent to the brightness of 9W energy-saving lamps, so in places where 9W energy-saving lamps are used, change to 3W LED lights, which is equivalent to power saving.

Under the same brightness conditions, LED lamps save 40% less electricity than energy-saving lamps.

The above is the power level of the bulb light.

If it is a common fluorescent tube, with the same brightness, the LED tube can save 60 70 meters of electricity.

LED bulbs.

Under the same illumination, DU saves about 10 times more power than ordinary bulbs. If DAOLED is used in large quantities for lighting, the energy of the festival is considerable.

Target. The luminous efficiency of LEDs is 150lm w, while the luminous efficiency of ordinary bulbs (incandescent lamps) is 12 24lm w. That is, at the same luminous intensity, the power of LED is 1 10 to 1 8 of ordinary bulbs.

The brightness of an LED bulb equivalent to 10W is comparable to that of a regular 100W bulb.

Here's an example:

The general household fluorescent lamp is meter 40w

And the LED fluorescent lamp meter is 18W

The difference is 22w.

The same illumination energy saving is about 50%.

This depends on the comparison of different manufacturers, Nanning Jisenda Technology **** production of LED lamps under the same brightness energy saving, high power is more advantageous.

Energy-saving lamps save between 20-30% of electricity compared to incandescent lamps.

Around 1970, energy-saving lamps appeared at Philips in the Netherlands. At the time, this was a major breakthrough for Philips. The upper end of the energy-saving lamp is the lamp head, and the bottom end is the lamp structure.

The interface of this lamp is very similar to that of an incandescent lamp, and it can be mounted directly on the lamp holder of an incandescent lamp. In supermarkets, we will find that the tubes of energy-saving lamps are spiral tubes and U-shaped tubes.

Energy-saving lamps save more electricity than incandescent lamps.

Energy-saving lamps have many advantages, they are small in size and the construction of the lamps is very tight; The luminous rate is also high, which is very energy-efficient. Compared with incandescent lamps, its service life is about 7 times higher. The disadvantage of energy-saving lamps is that they start slowly, and when you turn them on, you can't see the light immediately, so you have to wait for a while.

On the other hand, when you look at things under energy-saving lamps, the color of the object will change. The heat radiation of energy-saving lamps is only 20%. The vertical ordinary lamp is the heat generated by the current through the filament, and the tungsten filament continues to gather the heat energy, so that the temperature of the tungsten filament reaches more than 2000, and the higher the temperature of the tungsten filament, the brighter the light will be.

Generally, when the light bulb emits light, a large amount of electrical energy is converted into heat energy, and a small part is converted into valuable light energy.

Summary. Hello, from the perspective of light efficiency, energy-saving lamps can save energy by 3 times compared with incandescent lamps. Because the incandescent light effect is about 20lmw, and the light effect of energy-saving lamps is about 60lmw.

If the power factor of the energy-saving lamp is about about the same power, and the power factor of the incandescent lamp is 1, so that the energy-saving lamp consumes more energy than the incandescent lamp, which is 40% higher. Therefore, energy-saving lamps can save 60%-70% of electricity by replacing ordinary incandescent lamps, and the life span of energy-saving lamps is more than 6 times that of ordinary incandescent lamps.

If the power factor of the energy-saving lamp is about about the same power, and the power factor of the incandescent lamp is 1, so that the energy-saving lamp consumes more energy than the mold-resistant incandescent lamp, which is 40% higher.

Therefore, energy-saving lamps can save 60%-70% of electricity by replacing ordinary incandescent lamps, and the life span of energy-saving lamps is more than 6 times that of ordinary incandescent lamps.

Energy-saving lamps can save up to 80% of energy consumption per year compared to incandescent lamps.

How energy-saving lamps work

Energy-saving lamps use more efficient light production techniques, such as fluorescence and LEDs, which can produce brighter light while consuming less energy than incandescent lamps.

Energy consumption of incandescent lamps

The energy consumption of incandescent lamps is mainly lost in the form of heat, and only about 20% of the energy is converted into visible light. This means that 80% of the energy is wasted.

The energy-saving advantages of energy-saving lamps

CFLs use more efficient light production technology that converts more energy into visible light while reducing energy waste. This makes CFLs better than incandescent lamps in terms of energy savings.

Examples of energy-saving lamps

Environmental benefits of energy-saving lamps

The use of energy-saving lamps can reduce the negative impact on the environment. Since CFLs consume less energy, the demand for fossil fuels is reduced, which in turn reduces greenhouse gas emissions and the negative effects of global climate change.

The principle and working mode of incandescent lamps

Incandescent lamps are a common light source that works by passing an electric current through a filament to produce light. Filaments are usually made of tungsten or tungsten alloy because it has a high melting point and a long lifespan. When an electric current is passed through the filament, the filament is heated and visible light is emitted.

However, incandescent lamps also generate a lot of heat, making them less energy efficient.

Advantages and disadvantages of incandescent lamps

The advantages of incandescent lamps are low cost, adjustable brightness, and warm light. However, incandescent lamps also have some drawbacks. First, they are less energy efficient, with only about 5%-10% of electrical energy converted into visible light and the rest of the energy converted into heat.

Second, incandescent lamps have a relatively short lifespan, typically only a few thousand hours of use. In addition, they cause more pollution to the environment because the bulbs contain mercury.

Applications and alternatives to incandescent lamps

Incandescent lamps are still widely used in homes and commercial settings. In home lighting, incandescent lamps are able to provide a warm light and make the space more comfortable. However, as the importance of energy efficiency has become more and more important, a number of alternatives have emerged.

LED luminaires are considered an alternative to incandescent lamps due to their high energy efficiency, long life and environmental friendliness. Other alternatives include energy-saving and fluorescent lamps.

The development trend of incandescent lamps

As the focus on energy efficiency increases, the use of incandescent lamps is gradually decreasing. Some countries have phased out incandescent lamps and taken steps to encourage the use of more energy-efficient lighting products. For example, the European Union began phasing out traditional incandescent lamps in 2012 to promote sustainable energy development.

LED lighting technology is expected to continue to evolve in the future as a major lighting choice.
