How long can traditional fluorescent lamps be used when they are lit for 24 hours

Generally around 2500-3500 hours.

Attention to the use of fluorescent lamps.

Pay attention to the following points when using fluorescent lamps:

1) When using fluorescent lamps, pay attention to avoid frequent starting. The life span of the gaze lamp is generally not less than 3000 hours, and the condition is that it is continuously ignited for 3 hours each time it is activated. With the length of continuous ignition time for each start-up, the life of the lamp is also relatively longer or shorter.

Because every time it is started, the filament of the lamp is hit by high voltage, and the current at the start is 2 3 times that of the normal ignition. Initiation accelerates the consumption of electron-emitting substances on the filament, and when the electron-emitting substances on the filament are exhausted, the life of the lamp is over. If the lamp is lit for only 1 hour after starting it once, the life of the lamp is shortened to less than 70 meters.

Therefore, when using fluorescent lamps, try to avoid unreasonable frequent start-ups.

2) High and low power supply voltage will also shorten the service life of fluorescent lamps. When the voltage is higher than the normal working voltage of the fluorescent lamp, the current flowing through the lamp will undoubtedly increase, the loss of the filament will be accelerated, and the life of the lamp will be shortened. In addition, this can cause the ballast to overheat, resulting in a short circuit due to spillage of insulation or damage to the insulation.

However, the voltage is lower than the normal working voltage of the fluorescent lamp, which will also shorten the life of the lamp. Because the preheating temperature of the filament is low at this time, it is difficult to start, and the frequent flashing makes the loss of the filament too large. Therefore, appropriate step-down measures should be taken in places with high voltage, if the choke is connected or the supporting relationship of the ballast is temporarily changed (40 watt lamps temporarily use 30 watt ballasts, etc.); Also take care to reduce the number of starts during peak power hours.

In the place where the voltage is low, the high inductance reactance coil can be connected to both ends of the ballast to solve the problem of difficult start-up, or the supporting relationship with the lamp can be temporarily changed by the method of increasing the ballast.

3) Under normal voltage, the lamp and the ballast should be used together. Otherwise, the current flowing through the lamp will be abnormal, causing unnecessary losses, or causing difficulties in starting, and the opening reservoir can only be ignited by repeated beating, which increases the chance of the filament being bombarded by ions and accelerates the aging of the lamp.

It's hard to say, fluorescent lamps are also good and bad, as well as ballasts and many other reasons. If 24-hour illumination is a must, light-emitting diodes are recommended. Hope it works for you.

Ordinary lightingFluorescent lamp stoolGenerally, it is 40W, which means that it consumes kilowatt-hours of electricity per hour. According to the calculation of 24 hours a day, it is the kilowatt-hour of electricity, and after removing some losses, it is almost one kilowatt-hour of electricity per day. The kilowatt-hour is 1000 watt-hours (kWh denier reed

It's about a dollar.

The calculation method of the electricity consumed by the 5 watt (W) lamp when it is turned on for 1 hour: the power model rate (100 watts) and the electricity consumption time (1 hour) should be multiplied by the electricity consumption (kWh) and then multiplied by one day, 24 hours, and then multiplied by 365 days to get the kWh. Power consumption in one year (5*1 1000)*24*365= kWh.

Use incandescent lamps.

Things to look out for:

The rated voltage of the bulb at the time of use.

It should be consistent with the power supply voltage. In order to distribute the light emitted by the bulb well and avoid glare, it is best to install a moderate lampshade according to the requirements of the degree.

High-power incandescent bulbs should be installed with good ventilation in mind, so as to avoid overheating of the bulb and causing the glass shell and the lamp mouth to loosen, causing accidents. When the bulb is used in the open air, there should be rainproof facilities to prevent the bulb from breaking and being damaged in the rain.

At present, most of the fluorescent lamps are LED light sources. 20W is equivalent to the brightness of the original 40W lamp. Of course, there are other tung Qing lamps of different powers.

If calculated according to 20W, the actual local land power is about 21W, and the electricity consumption in one day (24 hours) is about: 21*24*. That is, half a kilowatt-hour of electricity.

The 10-watt lamp is turned on 24 hours a day, and the power consumption is calculated as 30 days a day.

The calculation formula is as follows: kWh x 30 = kWh (10 watts per hour of electricity).

1kw 1 hour ruler Zheng is 1 kilowatt-hour electricity, then 10w1 hour is the kilowatt-hour electricity.

1 kW * 1 hour = 1 kWh of electricity. The amount of electricity that an ordinary fluorescent lamp can use in a day should be calculated according to the power and time of use marked on the fluorescent lamp. For example, the power marked by the fluorescent lamp is 40W, and the night lighting is generally calculated for about 6 hours, and your electricity consumption in a day is about:

6 hours * 40 watts 1000 = degrees.

After dividing the wattage of a fluorescent lamp by 220. Multiply by 24 to get the number of electricity used in one day and one night.

It can be calculated that a thousand lights are one kilowatt-hour of electricity.

It takes about 1 kilowatt-hour of electricity to turn on 24 hours a day. Ordinary lighting fluorescent lamps are generally 40W, which means that they consume kilowatt-hours of electricity per hour. According to the calculation of 24 hours a day, it is a kilowatt-hour of electricity, and after removing some losses, it is almost one kilowatt-hour of electricity per day, and it takes about one kilowatt-hour of electricity for the light to be turned on for one day.

Generally, the electricity consumption of electric lights is related to the power of the electric lamp, if it is a 10W electric light, it needs to consume electricity in one day. If it is a 40-watt electric light, it needs to consume kilowatt-hours of electricity per day. The formula is calculated as power 24 1000.

Common electrical safety hazards in life

The power system is not up to standard: it is necessary to pay attention to the layout of the circuit must be responsible for professionals, which is very important. There are too many line joints, improper joint treatment, concealed lines, different lines follow the same line pipe, etc., and if there is a problem, it will take a lot of effort to renovate.

Excessive circuit load: It should be noted that with the increasing number of electronic products and electrical appliances, the load of the circuit is also increasing, and the use of a variety of high-power electrical appliances at the same time can easily cause short circuits.

The above content refers to Encyclopedia - Electricity.

It will not waste electricity, about the switch, it is generally believed that every time the switch is switched, the life is reduced by 4 hours.

Personally, I think:

1.When the fluorescent lamp is glowing, the capacitor parts in the circuit need energy to be charged;

2.The lamp should be preheated during the start-up process, during which the peak power is large, and the luminous efficiency of the lamp is low;

3.Take a 40-watt fluorescent lamp as an example, the power at start-up can reach about 42 watts, and the overall power consumption of the lamp is basically stable in the range of 40 watts after the preheating mold is started and works normally;

4.There is no theoretical basis for the claim that there are fluorescent lamps: once you switch them on, your life will be reduced by a few hours;

5.There are also some theories: the number of times the fluorescent lamp is switched on and off, which affects the service life of the fluorescent lamp, that is, the phenomenon of premature blackening.

Here I can say for sure that after nearly ten years of experiments, the number of lights will not affect the life of the fluorescent lamp (including blackening), a lamp tube is continuously switched on and off 100,000 times, which will lead to the luminous efficiency This is true and reliable, and a lamp tube is continuously switched on and off 15-200,000 times.

6.What we are talking about here, of course, does not include the phenomena that occur with ordinary electronic ballasts!
