High-efficiency, low-cost LEDs that may revolutionize lighting technology are available; is the active LED O LED the mainstream of future flat-panel TVs? The LED is built into the vodka bottle to realize the information interaction between the bottle and the mobile phone. It sounds interesting but who actually sells it? There is such a led light , it does not rely on electricity, relying on physical strength; bicycles driving at night, led lights will project a square grid, and also won the German "red dot design award" ... abandon the geographical time limit This issue of Xiaobian brings five new and meaningful LED technology research and development and innovative application sharing on a global scale. Please see below:
1, more efficient LED technology, stronger smart lights
Recently, scientists have developed a new high-efficiency, low-cost LED, or help promote the further popularization of LED technology. Florida State University assistant professor of industrial and manufacturing engineering Zhibin Yu said, "The newly developed light-emitting diodes potential to revolutionize lighting technology. In general, the cost has led lighting is a major problem, not enough to offset higher energy savings of LED Cost. New technologies may change this situation.†Zhibin Yu co-developed the technology with a team including postdoctoral researcher Junqiang Li and doctoral students Sri Ganesh Bade and Xin Shan.
According to the report, Zhibin Yu used a combination of organic and inorganic materials in the development of new LED technology. This material emits blue, green or red light and can be used to produce light bulbs. What is really special is that its manufacture is much simpler than the existing products on the market. In order to produce the desired product or achieve the desired results, most LED materials require engineers to "stack together" 4 or 5 layers of material. The material invented by Zhibin Yu requires only one layer. “In the future manufacturing process, handling multi-layer materials is a big challenge,†he said.
2. The "O" and "U" disputes in the future of flat-panel TVs
There is an industry paradox that OLED TV is a revolutionary product that represents the mainstream direction of flat-panel TVs in the future. Skyworth Group is the first enterprise in China to realize mass production and sales of OLED TV, and is also the first company in China to introduce Dolby Vision technology in 4KO led products . A few days ago, at Skyworth’s Beijing New Product Launch Conference, Deng Qingyun, a Chinese-American professor with the reputation of “the father of OLEDâ€, sent a congratulatory letter from the United States, indicating that OLED is very suitable for display devices and praised it as the history of OLED. Once again, development is strongly promoted. According to reports, "the ultimate high contrast brought by the perfect blackness, but also has a precise and balanced color", compared with the traditional LCD TV, OLED TV's image performance is remarkable, shocking. Under the premise that the production cost of OLED TV panels is significantly reduced and the yield rate is greatly improved, China and the global market will usher in a period of rapid growth. However, at the same time, there are also “unmatched†industries that “do not agreeâ€.
Before the new OLED TV launch conference of Skyworth, the Hisense Group, which took 7 years to tackle U led display technology, pointed out that there are still some defects in OLED TV at the Shanghai media communication meeting. They believe that in the face of various technical problems at this stage, there is still no conditions for large-scale promotion. In the end, they are not worried about it. "OLED is a self-illuminating device. It does not require a backlight module. Once it becomes the mainstream of the market, When Chinese companies can only become distributors and porters of foreign brands, OLED TV 'screens' account for nearly 90% of the cost of the entire TV set, so the OLED machine made by Chinese brands can only do the remaining 10%. The work, ie the motherboard and the base".
3, wine bottle packaging linkage LED function
Bottle packaging has become so "new", consumers are turning their attention to the bottle, isn't it too overwhelming? Brandea Laidlaw, founder and CEO of Medea Vodka, does not think so. He said: Drinkers are eager to personalize new experiences. For example, the two-dimensional code technology on the label of the bottle and the music of the bottle cap, etc., the application of these new technologies makes the information interaction between the bottle and the person become more and more dynamic and dynamic, but this is obviously not enough, it is reported that recently Some manufacturers have built the LED into the vodka bottle to realize the information interaction between the bottle and the mobile phone. They add functionality to LED-enabled vodka bottles, using Bluetooth technology and proprietary applications to connect, allowing users to remotely set and display scrolling information.
It is said that the popularity of mobile phones has made it a daily information processing center for people to connect and interact with wine bottles. This technology will make various possibilities for future bottle packaging. Expandability. Laidlaw said: "Medea's patented LED technology provides consumers with a platform for social interaction. This is very new and interesting! In the future, there will be more companies from nightclubs to companies using large and small companies to use Medea technology to connect with them. Customer communication.†He always believes that consumers who are looking for the latest creative gifts will be willing to pay extra for the quality and unique experience of the bottle.
4, LED lights that can be lit by gravity
This is a headache for many developing countries that still do not have access to electricity. In response to this situation, the non-profit organization GravityLight introduced a "gravity lamp" that relies on the weight of a bag of sand to generate electricity and provide illumination. It is reported that as early as 2013, the first generation of GravityLight GL01 successfully completed crowdfunding in Indiegogo. At that time, it received support from more than 6,000 people and raised nearly 400,000 US dollars in one month. The popularity is evident. Today, the development team has developed a second-generation product, GL02, based on user feedback from the first generation of products, after extensive testing and improvement.
The principle of gravity LED lights is to obtain electrical energy by converting energy into each other. It takes a few seconds to pull the 12 kg sandbag to a certain height by pulling the bead chain. Once it is let go, the sandbag slowly descends at a speed of 1 mm per second under the action of gravity. During the descent, the transmission drives the generator to generate electricity, and the gravity lamp begins to emit light. When the sandbag drops to the lowest point, the gravity light stops working. The lighting time depends on the installation height. Under normal circumstances, it can be installed at a height of 1.8 meters, which can maintain more than 20 minutes of illumination, and the longer the maintenance time. What is rare is that it does not release any substances and is very clean and environmentally friendly. In addition, its use is still known as "zero cost", in addition to the cost of buying products, perhaps the need to lose is the "rice money", because 30 minutes to raise a heavy weight, you may have to eat more food and long effort.
5, the gospel of the night bike rider
Because of the unfavorable observation of road conditions, cycling at night is dangerous. To cope with this problem, an LED projection lamp called "Lumigrids" will project a square grid on the ground in front of the bicycle. Through this twisting of the grid, it is easy for the rider to find pavement grooves or obstacles. The developer of Lumigrids, an engineering technician at Sichuan University, said the design was a retrofit of traditional bicycle lights. Traditional bicycle lights can create shadows when they hit a depression or a protruding obstacle. Sometimes it is difficult to judge the condition of the road. In contrast, Lumigrids' grid changes are much more intuitive.
Currently, this projection device supports 3 modes to adjust the grid size with different usage scenarios. Among them, the grid size of the normal mode is 140 x 180mm; the high speed mode is 140 x 260 mm; and the team mode expands the grid to 300 x 200 mm. Like ordinary bicycle lights, Lumigrids' lighting itself is also very easy to attract the attention of pedestrians and cars, which can greatly improve the safety factor of night riding. The entire device has only one button for switching and mode switching, and can also be driven by the power generated by the wheels or by the battery. It is reported that Lumigrids grid LED lights have won the first place in the "Best Design" unit of the 2012 Red Dot Design Award competition.
