How much energy-saving knowledge do you know about household lighting?

How much energy-saving knowledge do you know about household lighting? The lighting used in daily life is essential. We use daily lighting at home, and the daily lighting also requires a lot of electricity, which is a waste of energy. So how can we achieve both energy saving and lighting? Here are some energy-saving tips for LED lamps, hoping to help you. 1. Energy-saving lamps should not be switched on and off frequently Energy-saving lamps consume the most power when they are started, and each switch will reduce the life of the bulb by about 3 hours, so it is recommended to reduce the switching frequency of energy-saving lamps as much as possible.

2. Reasonably choose the degree of illumination. For incandescent lamps, generally speaking, 2 watts per square meter of bathroom lighting is enough. 4 watts per square meter is enough for restaurants and kitchens. The study and living room should be larger, requiring 8 watts per square meter; the lamps on the desk and bedside table can use 15-60 watt bulbs, preferably no more than 60 watts.

If the incandescent lamp used for indoor lighting is changed to an energy-saving lamp tube, the 18-watt energy-saving lamp tube is equivalent to the brightness of a 40-watt ordinary T8 fluorescent tube. If an electronic ballast is used, the energy-saving lamp can be started when the voltage is 150 volts. At this time, its power consumption is only 0.1 watts per hour, which is low and safe. Gradually accumulate dust, resulting in a decrease in output efficiency, so the lamps should be cleaned regularly at least once every three months to maintain the output efficiency of the lamps. When lamps and fluorescent tubes are used to 80% of their service life, the output light beam is reduced to about 85%, so it is advisable to replace them before the end of their service life. For office buildings with a large amount of lighting, regular replacement of light sources is especially important. In addition to saving labor costs for replacing lamps and improving indoor illuminance, it can also save electricity.

5. Replace low-efficiency light sources or lamps with LED lamps instead of incandescent lamps. The power consumption of incandescent lamps is about three times that of LED lamps. For places with long lighting time or infrequent switching operations, such as living rooms, bedrooms...etc. The incandescent lamp is removed and replaced with an energy-saving lamp series light source, which can immediately achieve the purpose of saving electricity. Power saving, energy saving Starting from you and me, starting from the little things, energy saving and environmental protection - just to continue the wonderfulness of the earth! .
