new led lighting technology Lighting technology leading the way in energy conservation
Imagine replacing your life.Room lights with walls will light gently, or your regular glass windows will dim with the push of the button.One day, such a dayWizards could save a lot of energy for California and the United States.-In addition to bringing the aesthetic taste of Jetsons into tomorrow's family (good or bad ).At the same time, researchers are designing less energy for the future --Save gadgets that may be ready in time to help ease the energy problems California is facing right now.Technologies under development include: testing unusual ceiling lights at the Bay Area Post Office;Better luminous performance than a monotonous, low-brightness micro-fluorescent lampglow ancestors;A flexible plastic tube that glows, sending out neat small beams of light;And the indoor version of the bright sulfur light, which currently lights up the huge parking lot at night.If the history of the past thirty years can be used as a guide,Saving technology is not just an odd plan like flying cars and atomic technology --In the 1950 s version of popular science and similar magazines, power blimps was hyped.Rather, energy-Saving technology is already an obscure hero of technology at the end of the 20 th century, and since the last "our energy runs out", it has saved the country energy equivalent to many nuclear power plants!"The amazing thing about 1970.The next time your smug friends and relatives treat California as an "energy pig", you can tell them that in fact, we use only half of the electricity per capita in other parts of the United States.The main reason: there are prescient sources of energyProtection rules at that timeGov.According to senior Energy, Jerry Brown 20 years agoThe art of conservation scientists Rosenfeld.Brown and the California Energy Council have been widely ridiculed as "governor moon Bohm" and they think it would be wiser to develop tough energy --Protection standards for construction and electrical appliances, rather than building new nuclear power plants-"It turned out to be the case," said Rosenfeld, a current member of the Energy Council and former czar of energy-saving science at Lawrence Berkeley National Laboratory, which is primarily funded by the United States.S.Department of Energy.With the changing political winds of the past 30 years, laboratory scientists continue to design energy --Although at first glance the new technology does not look exciting, it saves technology.For example, the witness is testing the lights at the Post Office in rodieu.The light is a long and thin tube that directly targets the light on the Mail of each operatorThe sorting station, instead of wasting it all over the place.Lawrence Berkeley's researchers calculated that it was a simple innovation, but it reduced the energy cost of lighting by 70%.Similarly, they recently invented a new type of highPerformance, energyMichael Siminovitch, a researcher at the Berkeley Lab, said the efficient desk lamp "can greatly reduce our current power problems in California while improving the quality of lighting ".The lamp consists of compact fluorescent lamps that can be manipulated to guide light in different directions--Toward the ceiling, for example.This allows usersAdjust lighting conditions according to their precise needs to overcome widespread complaints about first-'s dimness and poor designPower generation-saving lights.Only one new light is used-The fourth is 150 energy.Incandescent lamp or 300-Watt halogen lamp.They were on the battlefield.The laboratory was tested in collaboration with the Sacramento Municipal Utilities area (SMUD), Southern California Edison and Pacific Gas and power companies.Looking to the future, the old people --Older incandescent lamps may be challenged by electronic LEDs or lampsLEDs for video recorders and alarm clocks.These dim little lights may eventually become bright enough and white enough to start replacing traditional lighting sources.One problem: refraction or bending of light.Everyone sees what happens when a person inserts a straw into a glass of water-The submerged part of the straw seems bent.In the semiconductor material used in the LED, most of the light generated inside is so bent that it reflects back into the LED-That is, it can't escape.Therefore, the current light-emitting diode is not enough to attract a huge commercial market.However, engineers at Lawrence Berkeley and elsewhere are designing new LEDs to send out more light.One of them is Steve Johnson, a physicist who believes the led will eventually be brighter than a normal bulb.He noted that color LEDs have been used in some traffic lights.By mixing LEDs that emit different wavelengths of light together, white light can be producedLED lights, Johnson said.(White light is a mixture of all other light wavelengths.According to Johnson, led may have an impact on energy bills."One-The third energy we use in commercial buildings is lighting.So anything we do to reduce lighting costs will help with the energy crisis."Laboratories across the country are trying out a variety of strategies.Forgot to turn off the iron before you drove out of town?MIT's Media Lab is developing appliances that can be turned off remotely via a computer modem as part of its "Kitchen Sync" program.The same project is working on how to create an electronically connected home in which the appliance will open itself for non-essential work ---Say, wash the clothes--Only if there is no risk of circuit overload.Super-Efficient refrigerators using "magnetic" refrigerants are being tested at Ames Labs, a federal-funded laboratory in Ames, Iowa.Scientists there are using the "magnetic cooling" method to replace the compressed gas emitted by a typical refrigerator.Physicists have long known that some materials become hot when they are magnetized and cool when they are demagnetized.Even today, the energy consumption efficiency of refrigerators is much higher than before.The federal energy standard for refrigerators, which came into effect on July 2000, requires them to burn only one-25 years ago, Rosenfeld pointed out that their predecessors were equally energetic.Better yet, modern refrigerators are larger and do not use fluorine-containing carbon, which is believed to destroy the ozone layer that protects the planet from cancer, he added --Causing ultraviolet radiation"It's just a matter of designing them correctly," Rosenfeld said .".
