We have been using electric lights for lighting in all kinds of occasions, day and night. Some are for effect and some are for lighting. How can we save so many lights? Here are a variety of tricks on this website. Let's have a look.
Daily lighting power saving tips
Try to choose energy-saving lamps
Energy saving lamps save more than 80% of electricity and save energy. The service life is long, which is 6 ~ 10 times that of incandescent lamp. The service life is up to 8000 hours, and the light efficiency is six times that of an ordinary bulb. Comfortable light, no stroboscopic, protect eyesight.
Do not switch energy-saving lamps frequently
For energy-saving lamps, frequent switching not only does not save power, but also damages the service life of energy-saving lamps. The power consumption of energy-saving lamps when they are turned on is three times that of normal use. Switching on and off energy-saving lamps once is equivalent to energy-saving lamps that last for 10 hours. Therefore, switching on and off energy-saving lamps frequently consumes more electricity. Moreover, the instantaneous high voltage when the energy-saving lamp is turned on is twice the normal voltage, and the light will be stable after turning on the lamp for 5 minutes. Therefore, frequent switching is very easy to damage the energy-saving lamp.
The light should be turned off when leaving the room for more than 10 minutes, rather than switching on and off as frequently as incandescent lamps.
Select watts according to area
Considering the room space and lighting brightness, the bulb power is too large, wasting electric energy and easy to heat, which may lead to various accidents; Optional power is too small and can not achieve the ideal lighting effect. The following standards can be referred to: the lighting light for 15 ~ 18 square meters is 60 ~ 80 W; 30 ~ 40 m2 at 100 ~ 150 W; 220 ~ 280 w for 40 ~ 50 square meters; 300 ~ 350 W for 60 ~ 70 square meters; 75 ~ 80 square meters, 400 ~ 450 W.
Usually, 2 W per square meter is enough for the lighting of the bathroom, 4 W per square meter for the restaurant and kitchen, and 8 W per square meter for the study and living room.
The desk lamp on the desk and bedside table can use 15 ~ 60 W bulb, preferably no more than 60 W.
Try to choose natural light
The sunlight outside during the day can be used for indoor office and study without turning on the lights. If the effect is not good enough, you can hang more mirrors on the wall.
Many people like to install many gorgeous lights on the ceiling when decorating. In fact, this is not desirable. On the one hand, it costs electricity and on the other hand, it is also a waste of money.
Proper installation height
If the indoor height is relatively low (about 2.6m), it is recommended to choose ceiling lamps. If the height of the living room is high, it is best to choose chandeliers.
Multiple lighting fixtures
Several kinds of lamps with different power can be installed, which can achieve the effect of warmth, tranquility and power saving. There is no need to turn on the ceiling lamp that consumes the most electricity all day.
Reflective electricity saving method of aluminum foil paper
The smooth surface of aluminum foil paper has reflective function, which can improve the brightness. If aluminum foil paper is pasted on the lamp, it can indirectly achieve the effect of power saving, but it should not be used on halogen lamp and incandescent bulb lamp with high temperature, so as to avoid danger.
Replace the new lamp in time
If you want to save electricity, you should replace all the bulbs at home with energy-saving lamps as soon as possible.
Power saving tips for other household appliances
1、 Air conditioning power saving tips
1. Air withering is the "King" of power consumption in summer. When using air conditioning for refrigeration, install thickened curtains and open fewer doors and windows to reduce the impact of sunlight and heat. In addition, keep the air outlet pipe of the air conditioner unblocked, and clean the air conditioning filter screen once a half month to ensure that the air supply outlet is unobstructed and reduce the loss caused by blockage.
2. If the indoor temperature is set between 25 ℃ - 28 ℃, the power consumption will be reduced by 6% compared with the state below 25 ℃, and the power saving effect is very obvious.
3. Dust and other pollutants in the ventilation duct on the air conditioner block the vent, which will reduce the refrigeration efficiency. After cleaning, the air volume can be increased by 10% to achieve energy-saving effect. Therefore, when using air conditioning in summer, special attention should be paid to cleaning.
4. The compressor cannot be started frequently. It must be started every 2-3 minutes after shutdown, otherwise it is easy to burn the compressor due to overload and consume electricity.
2、 Refrigerator power saving tips
1. The refrigerator should be placed in a cool and ventilated place as far as possible, and the distance from the wall should be more than 10cm, which is conducive to heat dissipation. Fruits and vegetables and other foods with more water should be wrapped in fresh-keeping bags and then put into the refrigerator to avoid water evaporation and increase defrosting energy consumption.
2. In midsummer, it is most suitable to adjust the refrigerator to 5 ℃ and the freezer to minus 14 ℃. Due to the low temperature at night, which is conducive to the heat dissipation of the condenser, making ice cubes or cold drinks in summer should be arranged at night.
3. Refrigerated goods should not be placed too tightly, leaving gaps to facilitate the circulation of cold air. In this way, the cooling speed of food is relatively fast, reducing the operation times of compressor and saving electric energy.
4. When putting fresh fruits and vegetables in the refrigerator, be sure to spread them out. If fruits and vegetables are piled together, it will cause external cooling and internal heating, which will consume more power.
3、 Power saving tips for washing machine
1. Dip first and then wash. Before washing, soak the clothes in fluid soap or detergent solution for 10-14 minutes to make the detergent work with the dirt on the clothes, and then wash them. In this way, the running time of the washing machine can be shortened by about half, and the power consumption can be reduced by half.
2. Color separation washing, light first and then deep. Washing clothes of different colors separately can not only wash them clean, but also wash them quickly. It can shorten 1 / 3 of the time than washing them together.
3. Rated capacity. If the amount of washing is too small, the electric energy will be consumed in vain; On the contrary, washing too much at one time will not only increase the washing time, but also cause the motor to turn over negative, which will not only increase the power consumption, but also easily damage the motor.
4、 TV power saving tips
1. Today's TVs are basically liquid crystal TVs. Most of them have no mechanical switch but only remote control switch. Generally, the standby power is from 0.3w to 5W. Therefore, it is generally best to unplug the power plug and outdoor antenna after shutdown, which is energy-saving and safe to avoid accidents (such as lightning strike) when there is no one at home.
2. The contrast and brightness of TV should be well controlled for energy saving. The power of liquid TV is mainly in the backlight. Most LCD TVs have automatic brightness control, which will automatically adjust the brightness of the backlight according to the external links. It is recommended to turn on this function when watching TV, which will generally save 20% - 30% of power and save about 40% of power at most.
