Summer is approaching, it means that another peak of the season, you want low-carbon energy over the summer, how do you make the meter slow you down a little? Below the power sector in various positions of staff to answer your questions about LED lights power situation.

The problem one, LED lights to open all night long in the end spend much money?

Mr. Li of the house Taoxing is relatively small, nighttime on the toilet must go through hall, therefore, in the hall Ceiling Tops a probably 4 m of the LED lights with, are the 1 meters 60 beads, convenient nighttime to walk. Because applied for a peak and valley electricity, Mr. Li intend to all night driving a LED lighting. But his wife very much opposed to, think that the LED lamp beads multi-, power consumption is not small, to open a the evening is not worthwhile.

Power Supply Bureau transport inspection overhaul squad leader replied:

Available in the market common LED lights band for the 5050 SMD encapsulation format, this kind LED lamp beads Working voltage is generally In the 3.2-3.4 volts between, the power is 0.18W-0.2W or so. One meters LED lights with a 60 lamp beads, low power consumption usually in the 9W to the 12W between.

Mr. Li of the house li there are 4 m LED lights belt, if Du driving a, the hourly the energy consumption of maximum for the 48W, than the an ordinary fluorescent slightly larger some. If from 22:00 to next day 8:00, open 10 hours, Lee home LED lights with power consumption 0.48 degrees. According to the first step of the Valley Electric 0.288 yuan / kWh of electricity to count, which is about 0.14 yuan.

The problem two, Readily Guan fluorescent tube and save do?

Miss Chen home the hall to use 40W's ordinary fluorescent, the old house daylighting is not good, the evening habit put lamp has been open. Tariff January copy after, her mother felt turning off lights energy-saving, from the lobby to the kitchen for a few minutes, should the hall lights are switched off.

But I heard fluorescent lamp at startup when the current particularly large, frequent switching the contrary does not power-saving, the fact truly sullied by money? Readily off lights in the end be able to Province, how much electricity?

Electricity Generating Authority of electricity inspection Ban squad leader replied:

Fluorescent lamp turned on the moment will indeed appear an instantaneous's large current, is approximately normal working circumstances of the 5 to 7 fold. But This current Change Time extremely short, this the instantaneous large flow energy consumption probably the equivalent to the normal Working Power the lower 1 millisecond energy consumption, can be ignored do not count.

Conclusion is that fluorescent lamp although not power-hungry, but the turn off the lights still than the turn on the lights want to power-saving.
