Description

A kind of electricity-saving lamp note of switching regulator remote meter reading is taken device

Technical field

The utility model relates to a kind of electricity-saving lamp, and particularly a kind of electricity-saving lamp note of switching regulator remote meter reading is taken device, is applied to the universal use of energy-conservation lamp.

Background technology

At popular low-carbon (LC), further popularize today of electricity-saving lamp, more energy-conservation as LED (semiconductor lighting) light fixture of home lighting than general electricity-saving lamp, but fancy price has stopped that it enters the paces of family.Talk about LED, what people at first expected is the electronic display that large-scale public place uses, or the large-scale light fixture of each scenic spot use.The LED lighting of in fact all kinds of family expenses is developed.These light fixtures have been included each kind of household light fixtures, not only power saving, and also very attractive in appearance, decorative effect is fine.Compare with conventional light source, the power consumption of household LED lamp has only about 6% of conventional bulb, also wants power saving 50% than energy-saving fluorescent lamp.And the led light source life-span is long, can use 25000 hours, and the brightness behind the light decay still can reach the light efficiency of the brand-new fluorescent tube of tradition.In addition, because the household LED light fixture does not have stroboscopic, radiationless, unleaded, no mercury, not only favourable health, and have good environmental-protection function.The LED lamp of 8 5W has only been installed in more than 40 square metre stateroom, just makes whole room penetrating bright.We can say that under the background that current energy-saving and emission-reduction pressure continue to strengthen, selecting for use energy-saving efficiency to surpass 90% LED lamp is selecting greatly of cutting down the consumption of energy.The high temporary difficulty of price is popularized, and in the market, no matter be large-scale house ornamentation sales field or building materials market, does not all have businessman to sell the household LED light fixture in batches.Citizen will buy, and can only arrive in the minority light fixture brand shop and buy, and the choice is little.High-quality LED home lighting and decorative lamp, price are about 10 times of ordinary lamp and lantern, allow a lot of citizen be difficult to accept.The most cheap LED lamp on sale on the market, nominal power 0.9W (being equivalent to the 25W incandescent lamp), price is also wanted 30 yuan, and price is 6 times of equal brightness incandescent lamp, 2 times of common energy-saving lamp.And the price of LED desk lamp is often up to eight or nine hundred yuan, and the import brand price is then wanted thousands of units, is 10 times of general desk lamp price.

The LED lamp of height, thing U.S. of how agreeing to reduce the price asked enters the problem that family is not only country, also is the problem of manufacturer.Have only the family of allowing to feel and select the LED lamp for use, do not need to consider price problem, finally just can enter most of families.

Nowadays, global warming, weather begins to worsen; Chinese Government actively pushes forward energy-saving and emission-reduction for responsible to global warming; In energy-conservation project, green illumination becomes the first-selected factor that country advances reducing energy consumption, and green lighting technique is very ripe, and the energy saving space is big; Simultaneously, green illumination also is related to problems such as health, and not only energy-conservation as electricity-saving lamp, its three primary light source can also be protected people's eyesight; Electricity-saving lamp is directed to factory, does not influence the running of equipment, and the investment payback time is less than half a year.

State Council has set up energy-saving and emission-reduction group specially, and in China from 2008,1.5 hundred million electricity-saving lamps were promoted in the inherent whole nation in 3 years, and annual 50000000; Finish the work in 2008 wherein, the resident buys the electricity-saving lamp of state subsidies, state subsidies 50%, large client buys, state subsidies 30%.In any case but country's subsidy electricity-saving lamp, the price of electricity-saving lamp all can be higher than ordinary incandescent lamp.

Summary of the invention
