Candidates For Next-gen LED-based Datacoms
Candidates For Next-gen LED-based Datacoms
UK researchers show how organic semiconductors, CQDs and perovskites can be used in LED-based optical communications systems A new paper from the University of Surrey and the University of Cambridge has detailed how two relatively unexplored semiconducting materials can satisfy the telecommunication industry's hunger for enormous amounts of data at ever-greater speeds.LED-based communications techniques allow computing devices, including mobile phones, to communicate with one another by using infrared light. However, LED techniques are underused because in its current state LED transmits data at far slower speeds than other wireless technologies such as light-fidelity (Li-Fi).In a paper published by Nature Electronics, the researchers from Surrey and Cambridge, along with partners from the University of Electronic Science and Technology of China, examine how organic semiconductors, colloidal quantum dots (CQDs) and metal halide perovskites (perovskites), can be used in LED-based optical communications systems.The research team explored efforts to improve the performance and efficiency of these LEDs, and they considered their potential applications in on-chip interconnects and Li-Fi.Aobo Ren, the co-first author and visiting postdoctoral researcher at the University of Surrey, said:“There's excitement surrounding CQDs and perovskites because they offer great promise for low-power, cost-effective and scalable communications modules.“Although the conventional inorganic thin-film technologies are likely to continue to play a dominant role in optical communications, we believe that LEDs based on these materials can play a complementary role that could have a sizeable impact on the industry.”Hao Wang, the co-first author and PhD student at the University of Cambridge, said: “Future applications of LEDs will not be limited to the fields of lighting and displays. The development of LEDs based on these solution-processable materials for optical communication purposes has only begun, and their performance is still far from what's required. It is necessary and timely to discuss the potential strategies and present technical challenges for the deployment of real-world communication links using these LEDs from the material, device and system aspects.”Jiang Wu, the corresponding author from the University of Electronic Science and Technology of China, said: “Photonic devices for the Internet of Things (IoT) and 6G communication systems need to be high-speed, low-cost and easy to integrate. Organic semiconductors, CQDs and perovskites are promising materials that could be used to complement and/or compete with conventional inorganic counterparts in particular optoelectronic applications.”Wei Zhang, the corresponding author and Senior Lecturer from the University of Surrey, said: “IoT and 6G communication systems represent a trillion-dollar market in the next few years. We are proud to collaborate with the top research teams in this field and accelerate the development of emerging data communication technology for rapid entry to the market in the next decade.”'Emerging light-emitting diodes for next-generation data communications' by Aobo Ren et al; Nature Electronics 2021

This spray type soft ceramic heat dissipation paint can be directly sprayed on the outside of LED lamps and lanterns, which is easy to operate and can be adapted to various shapes of heat dissipation structures, and can also be adjusted to different colors to meet the needs of landscape design. The soft ceramic particles in the spray type heat dissipation paint are treated by nano technology. The fine particles are not only easy to be operated by the spray gun, but also make the heat conduction particles on the same coating area more and denser, make the area of temperature volatilization and dissipation larger, and make the heat energy of LED lamps quickly transmit out. Soft ceramic heat dissipation paint is a thermosetting material, which conforms to ROHS environmental protection and Safety specifications. The construction procedure is simple and does not need any special machines and tools. After baking, it can withstand the high temperature of LED for a long time without quality change. LED street lights, LED landscape lights, or LED billboards that are used outdoors will also face acid and alkali damage from wind and rain, acid rain, bird droppings, air dust, black smoke emissions, etc. Therefore, the spray type soft ceramic heat dissipation paint must have the characteristics of acid and alkali resistance, and the range of acid and alkali resistance is PH3 11, which can effectively protect the appearance of LED outdoor lamps from erosion. 100 watt led street light SL03 specification Model No.: SL03–100W Power(W): 100W Light Efficiency: 100–150Lm/W Voltage(V): AC100–277V CRI(Ra): >70 Power Factor: >0.95 CCT(K): 30006000 Environment Temperature :-4050℃ Life Time(H) : ≥50000 Ctn/Pcs: 1 LED: Epistar/CREE Model No.: SL02–180W Power(W): 180W Light Efficiency: 100–150Lm/W Voltage(V): AC100–277V CRI(Ra): >70 Power Factor: >0.95 CCT(K): 30006000 Environment Temperature :-4050℃ Life Time(H) : ≥50000 Ctn/Pcs: 1 LED: Epistar/CREE 100 watt led street light for sale 100 watt led street light for sale,Shanghai JingRui lighting is a professional enterprise integrating research and design, production, sales and service.Our main products include 100 watt led street light, LED Grow Light, HID Flood Light, Ballast and Bulb, etc. which are widely used for mobile light tower, construction sites, stadium, parking lot, road, ports and docks, etc. Free Quotes.

Why?I'll tell you, my choice is LED headlights.The following is my understanding of HID and LED.Advantages of Xenon Lamp1. The color temperature of xenon lamp ranges from 3000K to 12000K, of which 3000K is pure yellow, with the strongest penetrability in rainy and foggy days.4300K white to yellow, is the most comprehensive color temperature in rain, fog, sunny days and many road conditions (this is the standard for the original high-grade cars).5500K is the most natural color that is slightly white and close to sunlight.The 6000K color temperature contains more blue components, thus presenting blue and white light.Simply put, the higher the color temperature, the whiter the color, and the poorer the relative penetration, the shorter the illumination distance.2. HID is three times higher than halogen lamps in brightness efficiency, which has an obvious effect on improving the visibility of driving at night and in fog.3. Xenon lamps emit more than 2 times the luminous flux of halogen lamps. At the same time, the efficiency of converting electric energy into light energy is also increased by more than 70% compared with halogen lamps. Therefore, Xenon lamps have a relatively high energy density and illumination intensity.4. Save 1/2 of electricity. Halogen lamps consume more than 60W of electricity while xenon lamps only need 35W of electricity.5. Since xenon lamps have no filament, the problem of scrapping due to filament breakage will not occur. The service life of xenon lamps is much longer than that of halogen lamps. The service life of xenon lamps is equivalent to the whole operation time in the average service life of automobiles.6. Xenon lamp will not go out instantly in case of failure but will go out (or light up quickly) by gradually darkening, so that drivers can gain time in driving at night and pull over in an emergency.Disadvantages1. The requirement of a light-gathering is high. Special xenon lamps must be used. There are two factors for not gathering light.(1) The mismatch between bulb and lamp leads to, for example, installation of xenon lamp light source for lamps using halogen lamp light source; (This is also why it is not effective for car owners to change xenon bulbs directly. )(2) Bulbs and lamps are not properly installed, and the focus is not properly adjusted, which requires professional and experienced light distributor.2. Some models with the self-checking function will have fault lights on when they are installed because the bulb power of the original car is high (55W) and the power of the xenon lamp is low (35W), so the modified car will give an alarm when its power is not enough. As a xenon lamp, its starting instantaneous current is 8A, while the original car was started at 6.2A, so the circuit settings of the original car do not match. Professional installers are required for decoding and matching.3. The quality of the product is not up to standard. Incorrect installation may cause electromagnetic interference. This requires a professional installation technician to install.Advantages of LED Lamps1. Long service life, generally up to tens of thousands or even hundreds of thousands of hours. In the future, LED will be used for automobile lighting lamps, and lamps will not need to be replaced throughout the service life of the automobile.2. High efficiency and low energy consumption. The LED light source can directly produce red, amber and other colors required by automobile lamps without color filtering, without loss, and the utilization rate of electric energy is as high as over 80%.3. The light quality is high and belongs to environmental protection products. Basically, there is no radiation and "green" light source.4. LED has a simple structure, internal support structure, and is sealed with transparent epoxy resin around, with good seismic performance. 5. No delay in lighting, fast lighting response speed (nanosecond), suitable for objects with fast-moving speed.6. It is suitable for low voltage operation and can be completely applied to automobiles.7. LED occupies a small volume. Designers can change the lamp mode at will, thus diversifying the car shape. Automobile manufacturers favor LED, which is completely determined by the advantages of LED itself.Of course, compared with xenon lamps, LED lamps also have the following disadvantages1. The requirements of lamps are extremely high-since the requirements of lamps are more stringent at the single point of the light-emitting focal plane, this problem is also the reason why the lighting effect of LED lamps is most affected.2. High cost-Take LED reversing lamps as an example. One LED reversing lamp is close to 30 yuan, while the price of one bulb is only 5 yuan, most of which is the cost of LED lamps. High prices cause ordinary cars to be unable to install LED lights and the market cannot be popularized.3. The difficulty in popularizing LED car headlights is due to the fact that the LED light source is installed in a relatively sealed headlamp assembly, which has poor heat dissipation and easy light attenuation due to poor heat dissipation treatment, thus affecting the service life of the headlamp.4. There is no unified industry standard and the quality of products is uneven.5. It is difficult to design a light type. Because the vehicle lighting is different from the domestic lighting, the width, range and range requirements of the vehicle lighting are much higher than those of the domestic lighting.In general, xenon lamps and LED lamps have their own advantages and disadvantages. Judging from the matching of current light sources and lamps, if the lighting effect is the final judgment standard, the effect of HID xenon lamps is obviously higher than that of LED lamps which are not perfect enough, but judging from the overall development trend of science and technology, LED lamps will definitely be the mainstream in the future.Maybe you want to know more about LEDs in cars, you can visit myblog(vantenled.blogspot.com) or mywebsite(www.vanten.co.uk).

What Are the Benefits of a Chandelier Light ?
What Are the Benefits of a Chandelier Light ?
There are many reasons to purchase chandeliers for the home. This article provides a list of reasons why they should be chosen above all else. If you have not considered using chandeliers before then this article is for you. Here you will find all the reasons why it is the perfect type of lighting for the home regardless of taste and budget.1. Guys! Is it true that when a girl wears chandelier earrings they attract attention?that is so not true!!2. How low to the table does your chandelier hang?make sure it is not where you;ll be bumpin your head, my mother in laws is too low, i am always smackin my head on it, i hate it3. What kind of lightbulb(?) is in this chandelier?There is also something called El-Wire. It is a flexible cable that is fluorescent. It can be powered of batteries and is popular on clothes, like dancers - But the applications are endless for this glow wire.I bought 10 metres of this and it is really funky stuff. I bought really thin el wire for christmas decorations but you get various thickness.ExplanationEl wire is quite different from standard lighting. What makes it work is high frequency alternating currents and not really the input voltage. I have read that powering it up directly from 110vac or 220vac will light them up but it will be dimm because its on 50/60hz.The general standard indicates that the transformer box you get with it steps up (or down) to somewhere between 90120vac at 1000 Hertz - You can get transformers that can even power a few hundred feet by a AA battery up to several days. This high frequency is what excites the phosphor coating and causes it emits light. Regulating the frequency makes it brighter or dimmer. The input voltage also makes it brighter or dimmer but too much or too little voltage will deplete the phosphorus layer quicker. Unlike LED's el wire will eventually burn out and become really dimm.4. what should I pay for a used chandelier off new price?It depends on the quality and the maker. If it's a work of art, it can appreciate in value, and be worth many times it's original prices. If it's great craftsmanship, it can still appreciate somewhat. If it's well made, it can resist depreciation. If it's a "common" value, you can bet 50% off original price or better.5. What is the meaning of "chandelier"?"Chandelier" is a large round frame with branches that hold lights or candles. They are decorated with many small pieces of glass and hang from the ceiling6. I have a beautiful but HEAVY chandelier. Any creative ideas for its display (not hanging freely)?well instead of putting a chandelier you should put some spot lights or you could get help put the chandelier and when you are about to move just put some gypsum board on the hole and paint over it7. I have a chandelier bought from Czechoslovakia and wanted to change the bulbs to LED.?Measure the sockets. You know that it needs bigger bulbs than the ones you bought, so that's a start. It's possible the bulbs for that chandelier might not be available in the USA8. how high do I hang a chandelier over a dining table?up to you no standard height9. Where can I find a chandelier like this one?Go to Walmart or Home Depot, but that's the average price10. Are these chandelier earrings too big?depends where yur going, if its not too fancy place, yea they might be to big, but if yur going out to dinner or w/e there a good size :)11. Where to rent a chandelier and have it shipped?Have you thought of getting one at a consignment shop and then consigning it again when you are finished with it? We were just at a consignment shop yesterday and some people were buying furniture to stage their house with that intention. The woman there said that people do it all the time12. Where can I get a rattan or wicker chandelier or lighting fixture?This Site Might Help You. RE: Where can I get a rattan or wicker chandelier or lighting fixture?

How to Solve the "inferior" of the LED Factory Lamp
  Author :Green earth– LED Strip Lights manufacturersThe LED factory lamp product type is now a dazzling, of course, in this competition, the number of manufacturers of LED factory lamps has a stable trend, and now it is, the straight line of our products rises, and let users The head is faint, and I don't know where to choose. When we choose LED lamps, we need to observe the performance of LED luminaires from multiple aspects.From the general perspective. And the inferior LED factory lamp is very different. Inferior LED factory lamp products“inferior”Refers to the inferiority, performance of the work, and the virtual standard parameters, exaggerated promotion. In its appearance, its appearance is its appearance, work rough. Of course, the LED factory lamp is more fear is charged. So in the choice, we need to pay attention to the following aspects:If the LED factory lamp is long, you can look at it doesn't have a hot, if you are hot, then the heat dissipation of the LED factory lamp is not good, like this LED factory lamp will damage his service life. There is also the processing of the LED factory lamp light. This is also important. If the light is poor, then it will cause visual conditions that do not reduce the visibility of objects. If you have used it for a long time, it will easily reduce the vision of consumers. Therefore, we need to avoid LED factory lamps.“inferior”.Keywords: LED factory lamp
