Bright Idea: New LEDs Can Detect Off Food And Lethal Gases
Bright Idea: New LEDs Can Detect Off Food And Lethal Gases
New LED technology has potential to benefit firefighters, miners, the military, plumbers and households.(Source:University of Melbourne) Your smart device could soon be even smarter with a new infrared light emitting diode (LED) that is ‘tuneable’ to different wavelengths of light – it could enable your fridge to tell you when your food is going off and your phone to tell you if that Gucci purse is real. The technology has been developed by the University of Melbourne, the Lawrence Berkeley National Laboratory, the University of California, Berkeley, and the Australian Research Council Centre of Excellence for Transformative Meta-Optical Systems (TMOS). They have come up with a device that could identify a suite of gases, potentially including lethal ones, improving the safety of firefighters, miners, the military, and your local plumber. The work appeared in the journal, Nature. Infrared (IR) spectrometers are common laboratory equipment that can identify different materials by analysing their infrared signatures, which is invisible to the human eye. Just like an AM radio can be tuned to different frequencies of radio wave, IR spectrometers can be tuned to different wavelengths, giving a broad-spectrum analysis of a gas sample. However, these machines are bulky and expensive and not usually practical to take out of the laboratory and into the field. “Our new technology bonds a thin layer of black phosphorus crystals to a flexible, plastic-like substrate, allowing it to be bent in ways that cause the black phosphorus to emit light of different wavelengths essentially creating a tuneable infrared LED that allows for the detection of multiple materials,” University of Melbourne Professor Kenneth Crozier said. “This technology could fit inside smartphones and become part of everyday use.”For example, the bacteria found in meat release various gases as they multiply. The presence of these gases is a good indication that the meat is spoiling and is no longer fit for consumption.“The device placed inside a fridge could send a notification that meat is going off. When pointed at a handbag, it could reveal whether the bag is made of real leather or a cheaper substitute,” said Professor Crozier, who is also the Deputy Director of TMOS.Current materials that are used for IR photodetectors and light emitting devices can be difficult to manufacture, in large part due to the need for multiple layers of perfectly linked crystals. This new black phosphorus technology requires just one layer allowing the device to be flexible, giving it unique properties when bent.“The shift in black phosphorus' emission wavelength with bending is really quite dramatic, enabling the LED to be tuned across the mid-infrared,” said Professor Ali Javey, from the University of California at Berkeley, whose group led the work.Importantly, the device could make the work of firefighters, miners and military safer, allowing them to identify potentially lethal gases from safe distances as the ultra-thin, ultra-light devices can be placed on small drones. Flying such a drone over a building fire could tell firefighters what dangers they face and equipment they’ll need.The low-cost technology could also make its way into devices for use by plumbers and building managers.“Our IR photo detectors could be integrated into a camera so that we could look at our phone screen and ‘see’ gas leaks or emissions and be able to determine what kind of gas it is,” Professor Crozier said.

Almost any eye can see "fill or flash - light" if they know what their looking for. . If you have a killer sunset (like we do here in AZ) and you have your models pose with it behind them, there is no way you will get them unless another light source is used while the camera's settings are set for the sunset. Same with street lights, Vegas, New York and other land marks lit at night. A lil extra piece of the sun is needed in the way of a flash or such. . It is all so totally accepted, IF the exposures are done right and the photo is as you (or your clients) wanted. A Motorcycle or classy car going down the road at or near sunset. Same thing. You will NEVER stop the motion AND get the colors of the moment at the same time with out using a flash in conjunction with settings to get the back ground loght in and a f/stop to handle the flash (the camera's shutter speed is irrelevant here for the flash) if you understand and have done this kind of twilight shooting, mixing natural and flash lighting before. . So, Is using flash/ studio lights outdoors instead of natural light "more professional?"? . Yes. .!.Is it true that 2/3 of our electricity is used for lighting?if you count street lights and other exteriors that may be trueWhat are some recently installed Pink coloured towers in Chandigarh?Thanks for A2A.Yes, they are 4G mobile towers from Reliance Jio. These are camouflaged towers which can be installed in different shapes as one installed in Jamshedpur.nnReliance is changing the mobile tower installation scenario in India as the company is using green technologies to install more efficient towers. Moreover these towers also takes care of city's beauty (Aesthetics) and they can also be used to accommodate street lights, security cameras etc.What are some recently installed Pink coloured towers in Chandigarh?what are some recently installed Pink coloured towers in Chandigarh?My clutch pedal lost it's tension and hit the floor while engaging it to stop at a street light.?Cluth cable has snapped. . Not a difficult job to replace it, or the clutch pedal return spring has come adriftit is bad if I walk by a church and it goes black..?Street lights do thisStates and or cities that are bike friendly in the USA?I live in Indianapolis and we are starting to put in bike paths on the side of the roads but unless theres street lights theres no special lights for night time riding. allso most drivers are ***** and think the bike paths are for them to drive on and just ignore them. its basicaly like this every where in america hardly anybody ride bikes now and 99. 9% of drivers dont care if they nearly hit people. so expect that
LED Street Lamp Manufacturers: What Are the Advantages of LED Street Light Energy-saving Transformat
LED Street Lamp Manufacturers: What Are the Advantages of LED Street Light Energy-saving Transformat
  Author :Green earth– LED Strip Lights manufacturersWith the increase in people's energy-saving environmental awareness, the LED lamps have replaced the prosperity period of traditional light sources with the decline in price. LED is a new generation of light sources for efficient, energy saving and environmental protection. my country's outdoor road lighting accounts for about 30% of the electricity consumption of the entire lighting, which is closely related to people's production and life. Then what are the advantages of our LED street lamp manufacturers?As an important application of outdoor lighting, LED street lamp manufacturers:First, the life of the high-power LED street is 5-100,000 hours, in fact, the life of high-power LED street light depends on the following points:1. LED light source chip quality, light attenuation reduction.2. LED package quality. Consistency and reliability.3. LED is a cold light source, but the LED semiconductor itself produces heat. LED cooling, ensuring good working conditions for LEDs.4. Life quality assurance of power supply and constant current driver.Second, the energy saving efficiency is high, and the application of LED street lamp renovation project can not only save energy, but in fact, due to the durability of the luminaire, the economic efficiency of the application is also highlighted.For example, the total investment of 2 million LED stream renovation project is 4.89 billion yuan. After the transformation, only the electricity bill will be saved once a year to 1.5 billion yuan. Within the entire LED life (about 9 years), it can save power consumption of 10.8 billion kilowatts. It is equivalent to saving standard coal 3.70 million tons, reducing sulfur dioxide emissions, reducing 268 million tons of carbon dioxide emissions, reducing 70,000 tons of dust emissions The benefit is huge.Third, the LED is different from the traditional lighting, which has the characteristics of a point source, high brightness, narrow beam output. The uniformity of the light shot surface is controllable, and the limited light flux is sufficiently utilized to the effective irradiation range, and the street light is required to be the road lighting effect.After the original ordinary street lamp is transformed into a new LED street lamp with low brightness, high brightness and wide exposure, it has fully played the advantages of high-efficiency and energy saving of the LED street light, effectively improved road lighting, improved the public security environment, and travels for the masses. It has been convenient, and the LED street lamp manufacturers have accelerated the implementation of energy conservation and emission reduction, saving a large fees for the country.
