LEDs lights

Today we will discuss and understand some of the words used in an LED lighting systems, which will help you choose the best solutions for your applications or upcoming projects and understand why LEDs continue to outperform incandescent and fluorescent models. Early on, LED lighting was mostly utilised in business settings, but because to technological advancements, it is now mostly employed in home settings as well. growing numbers of consumers

 

LED

LED (Light Emitting Diode) is a semiconductor source of light which produces light when a DC electric current is run through it. The energy particles, photons, are released during this process. What you need to know, without getting too scientific, is that compared to fluorescent and incandescent models, LEDs are more effective at energy conversion into light. LEDs are more durable and produce less heat than conventional picture lights while using less energy.

 

 

 

Nowadays, You can have a small design with a thickness of few centimetres thanks to the built-in technology of LED. LEDs are being incorporated into a growing number of lighting fixtures today. Built-in LEDs have the benefit of enabling lighting producers to produce thinner and more streamlined fixtures. These cutting-edge LED models can be fitted in locations where no other embedded technology can due to their thickness. For instance, many LED users enjoy installing them in different arts.

 

Now that you are aware of the many LED lighting options, will discuss some types of LEDs.

 

Conventional light bulbs

 

Most homes have these kinds of LED lights. They are perfect for lighting up various places throughout the house, such as hallways and bathrooms etc.

 

Candelabra lights:

 

These LED bulbs have a reflector to increase their degree of brightness. For instance, they function best in your home as recessed lights. Additionally, they provide you with significant savings due to their low energy usage and availability in a variety of colours to match your design.

 

 

 

LED floodlights

 

These kinds of lighting are used in outdoor locations like sports stadiums or security lights. Floodlight bulbs generate a focused beam of light to a specific region or area in contrast to standard lights.

 

 

LED candlelight

 

Candlelight bulbs are more ornamental lighting for the home, as the name implies. They make excellent chandelier lights or restaurant tabletops because of their steady light. In addition, compared to conventional candles, they provide a cleaner and greener option.

 

 

Globe lights

 

These LED bulbs provide light in a variety of directions. Therefore, these bulbs are perfect for locations that demand the most illumination. For your home's lighting, you may, install globe lights.

 

 

 

Light  Tubes:

 

These are intended to replace standard fluorescent bulbs. They are a typical element in plenty of workplaces and classrooms. Numerous small LEDs are lined up along the tube length to produce the optimised light.

 

Life Of LEDs:

So how long does the LEDs last? The normal lifespan of an LED bulb is about 30,000 and 50,000 hours. A common incandescent light has a lifespan of roughly  some 1,000 hours. Unlike conventional light sources, LED ages very slowly over time rather than burning out. The LED technology no doubt a miracle, because of its long bulb life and low power consumption.

 

The ability to customise your own unique lighting scheme using various colour temperatures, intensity, warmness, and efficiency is one of the best things about LED technology.

 

 

 

Color Temperature Correlation (CCT)

 

The majority of LED lighting fixtures give users a choice of white colour temperatures. Scaling from 1,000 to 10,000, this temp, or CCT, is expressed in degrees Kelvin (K). The colour representation of these LEDs is the same as natural sunshine as Kelvin increases. While neutral whites usually have a temperature of 4000K, warmer whites often have a temp of 3000K or below. The White light that has a temp 5000K or above is described as cold. The typical temperature of LEDs for home and office lighting fixtures is in the range of 2500K to 5000K. Selecting LEDs for your projects, it is of great importance that you should take colour temp in mind.

 

Voltage and Wattage:

Before buying LED lights you must know the power consumption (Watt) and Voltage on which they work. Most the Led work on 12 V or 48 V. There are smaller LEDs which also work on 3 to 5 Volts. So, Before selecting your LED light you should Properly check the voltage and wattage.

These were some important points which we discussed. If you know better options please tells us in the Comments section. Thanks

Artificial rain

Northern hemisphere countries continue to experience heat waves, wildfires, and catastrophic drought, spurring climate scientists and technologists to experiment with the weather. Now, most interesting question comes to someone's mind is, can humans control weather? The answer is Yes, to some extent, humans can control the weather.

Cloud seeding, often known as artificial rain, is commonly employed nowadays to supply water to drought-stricken areas. However, it has been abused in the past.

 

China is currently experiencing its longest heat wave on record, with temperatures in the Sichuan province consistently reaching 40 degrees Celsius. The heat is driving the Yangtze, Asia's longest river, to reach the record lowest level, triggering a drought that, according to China's Ministry of Water Resources, is adversely affecting the drinking water of rural people in the country, its livestock, as well as agricultural growth.

In response to the dire situation, the Chinese government undertook an effort to induce rainfall through a process known as "cloud seeding."

 

What is the process of cloud seeding?

 

Clouds arise as water vapor-containing air rises into the atmosphere. It cools, and condenses into ice particles. A cloud arises when enough of the particles clump together. The frozen particles mix inside the cloud. When the combined droplets become large and heavy enough, they fall to the ground as rain, snow, or hail, depending on the temperature and other weather conditions.

 

Cloud seeding involves the addition of microscopic particles of silver iodide, a salt with a crystalline structure similar to that of ice, to clouds. This operation can be carried out using a plane or a drone, or the particles can be blasted up from the ground.

 

According to scientists, the technology allows water vapour inside clouds to be "tricked" into producing droplets surrounding the silver iodide particles. When these droplets get some weight, a process with the addition of silver iodide, they fall down from the clouds in form of precipitation.

 

 

Practical examples of cloud seeding:

In the 1940s, scientists at the General Electric Research Laboratory in the United States undertook the first experiments at cloud seeding. The approach is now employed in many countries throughout the world. China is the most recent example, and the method was previously used to make it rain before of the 2008 Summer Olympics.

 

Russia also used cloud seeding before of major holidays to prevent rain from ruining public celebrations. In order to assure a dry May Day celebration, Russia reportedly spent 86 million rubles (1.44 million euros or 1.43 million USD) in 2016. The weather in Moscow was sunny on the day of the event.

 

Today, the method is largely utilised to make it rain in drought-stricken areas. Aside from China, the United Regions has been practising cloud seeding, most notably in drought-stricken western states like as Idaho and Wyoming.

 

In the Vietnam War, the US used cloud seeding as a weapon to extend the monsoon season, interrupting the Viet Cong's supply chain and impeding their movement by making the land muddy with more rain.

 

In April 1986, Soviet air force aircraft seeded clouds travelling toward Russian communities near Chornobyl, where a nuclear power facility had just detonated. Moscow deemed the operation a success because the radioactive clouds did not reach Russian cities. Instead, they showered radioactive waste on rural Belarusian districts and the hundreds of thousands of people who lived there.

 

Why is cloud seeding contentious?

These latter two examples demonstrate how technology intended for the greater good may always be abused by those in positions of authority. Other variables, though, have some experts questioning whether cloud seeding is a wise idea.

 

One argument is that if you seed clouds over your region to prevent dryness, those clouds will not convey rain to the next region, where it would have delivered much-needed rain.

 

"If you make it rain in one spot, you minimise rain downstream," said David Keith, a Harvard University professor of applied physics.

 

Keith compared the process to "robbing Peter to pay Paul," referring to his studies on the nexus of climate science, technology, and policy.

 

"It simultaneously produces winner and loser," he explained.

 

Experts also warn that regulating the weather may be too difficult to accomplish and that it may divert attention away from traditional ways to combat climate change.

 

"Geoengineering, especially large-scale cloud seeding, is a risky experiment that can go away and have unanticipated repercussions," Vinas added.

 

"We should invest in adaptation and mitigation strategies if we wish to lessen the impacts of droughts or storms, which are especially severe in the context of present global warming."

Explaining Virtual Reality (VR)

Virtual reality technology is critical to the realization of Tele sensation. It creates a virtual world for viewers to explore and walk through, as well as interact with virtual things. The virtual world, like the actual world, provides us with a stereoscopic picture from the front or side, depending on our vantage point. One of the most essential elements of VR is the ability to enter and walk through the virtual world and handle virtual things via hand gestures.

 

What Exactly Is Virtual Reality?

The use of computer technology to create simulated settings is known as VR virtual reality. Virtual reality immerses the user in a three-dimensional environment. Instead of looking at a screen, users are immersed in and interact with the 3D world.

The simulation of human senses—all five of them—converts a computer into a vehicle for exploring new worlds. The only constraints to a fantastic VR experience are computational power and content availability.

 

The difference between VR (Virtual Reality) and AR (Augmented Reality):

VR uses sensory stimuli to generate synthetic environments. The behaviours of users influence, at least partially, what happens in the computer-generated world. Digital environments are representations of genuine places that exist apart from current physical reality.

In augmented reality, the real world is viewed directly or through a device such as a camera to create a visual, which is then supplemented by computer-generated inputs such as still images, audio, or video. AR differs from VR in that it augments the real-world experience rather than building a new one from scratch.

 

 

Working principle of Virtual Reality (VR) Technology?

Virtual reality's primary goal is to excite vision. Every VR gadget places one or two screens in front of the user's eyes, effectively eliminating any real-world interaction. Two auto-focused lenses are placed between the eyes and the screen. These adjust based on the user's posture and eye movement. HDMI connections or mobile phones are used to render on-screen graphics. A minimum frame rate of 60fps, a reasonable refresh rate, and a 100-degree view of the field are required for a truly immersive experience. Any disparity in these elements may result in lag for the user. To mislead our brain into believing the VR, a response time of 20 milliseconds or fewer is required.

Another source of concern with VR technology is cybersickness or ripping. It is caused by a discrepancy between the refresh rate and the frame rate, and it results in distorted visuals. This can be mitigated by restricting the frame rate to the monitor's refresh rate. Vertical Sync is the technology employed in this case.

 

 

 

Virtual Reality Applications

Virtual reality is now applied in a variety of sectors. We will look at several examples to see how it is assisting in specific industries.

• Automotive

• Healthcare

• Gaming

• Training

• Tourism

• Education

Today many well-known companies like Facebook, Vivo, HTC, Apple and Samsung are investing in VR technology. It is said to be the future trillion-dollar business.

WORLD'S MOST ADVANCED BROADBAND INTERNET SYSTEM

 Starlink internet works by delivering data across space, where it travels considerably quicker than fiber-optic cable and can reach far more people and places.

 RELATED ARTICLE

In today world, most of satellite internet services are provided by single geostationary satellites that orbit the earth at approximately 35,000 kilometres. However, Starlink is a satellite that orbits the planet at approximately 550 kilometres and covers the whole globe.

 

What exactly is Starlink?

In basic terms, Starlink is Elon Musk's Space X's satellite internet service. The goal of Starlink is to deliver global broadband internet access without the use of fibre or optical wires. Millions of people around the world lack access to high-quality internet, owing to the physical limitations of wires. Starlink intends to address this issue by delivering internet access via satellite.

 

What is NFT? Is It worth investing?

How does Elon Musk's Starlink function?

Starlink, as previously stated, is a satellite internet provider. This operates similarly to your present DTH connections in that a satellite sends signals to the dish on your roof, and then a device (in the case of DTH, a set-top box) transforms those signals. Similarly, in Starlink, satellites beam internet to a dish on your roof called a dishy (included in the Starlink kit), which then transmits the signal to the Starlink Wi-Fi router. The Wi-Fi router then translates the incoming signal and connects to the internet.

 

However, a strong signal between the dish and the satellite is required to give high-quality internet. To assure robust transmissions, SpaceX is using low-Earth orbiting satellites, which are around 550 km above the planet. As we stated before, these satellites have a limited area range and so it is necessary to use more satellites to provide internet access everywhere — in order to construct a satellite web. Consider it a network of satellites that are linked to one another and work in unison to give internet to every corner of the globe. SpaceX intends to launch thousands (perhaps 40,000) Starlink satellites to assure global coverage without service interruptions.

 

Where can I find Starlink?

Before you hurry to your computer and get Starlink, you should be aware that satellite internet is not available everywhere. Despite the fact that the internet is being transmitted from space, Starlink must obtain permission and licences from the government before beginning operations in a country.

 

Starlink is currently available in beta in the following countries:

 

• United States of America

• The United Kingdom (UK)

• Canada

• Australia

• Germany

• Portugal

• Denmark

• Chile

• Ireland

• Austria

• France

• Belgium

• Switzerland

 

It is important to note that even though these nations are supported, the service may not be available in all regions. We still recommend that you check Starlink's website to see if the service is accessible in your area. Enter your address in the "Service Address" section of the main page to check availability. If Starlink is not available in your area, the website will display a banner with the text. Hope this article helps you to understand what actually starlink is.

Feel free to contact us for any suggestion. Kindly, share with your friends.

Vivo 6G white paper Technology.

"Building a Freely Connected Physical and Digital Integrated World: 6G Services, Capabilities, and Enabling Technologies," the third 6G white paper from the Communications Research Institute, has been issued. The paper delves into the 6G architecture and supporting technologies that experts anticipate will change people's lives beyond 2030.

 

"As a prominent smartphone manufacturer, we are committed to empowering customers by making cutting-edge 5G devices cheap and accessible." Simultaneously, we have placed our eyes on the future, namely 6G," stated Qin Fei, President of vivo Communications Research Institute. "At the vanguard of research and development, we continue to investigate what a 6G future may look like and what technologies we will need to build to get there."

Over the last two years, the industry has progressively reached an agreement on the services that 6G might deliver and the key capability indicators that must be met. The development of associated critical enabling technologies is also gaining traction. With in-depth study and assessment of 6G business models and drivers, application scenarios, system design, and supporting technologies, the vivo Communications Research Institute has actively contributed to creating the future of 6G. vivo's latest white paper on 6G builds on two previous works published in 2020: 'Digital Life 2030+,' which provides insights into some of the many potential 6G digital scenarios for the next decade, and '6G Vision, Requirements, and Challenges,' which outlines vivo's vision for 6G, namely that 6G will enable convergence of the digital and physical worlds.

Capabilities and Services

According to the white paper, 6G will enable extraordinary communication, information, and convergent computing capabilities, serving as the foundation for an interconnected and integrated physical and digital world. According to the research, 6G will integrate communication, processing, and sensing into a single system. An integrated 6G network will not only link people to humans, but also humans to machines and machines to machines, enabling the creation of an entirely new digital universe. By 2030, it is projected that hundreds of billions of gadgets will be linked.

"We'll be able to deliver the next level of connection into every part of people's life with 6G." It will incorporate more access technologies, cover a bigger physical region, and give superior core capabilities, allowing it to enable more services," said Rakesh Tamrakar, Vivo's 5G Standard Expert. "By seamlessly integrating industry, transit, office, and households, 6G will significantly benefit society, from democratizing professional skills to improving emergency and catastrophe response."”

6G will broaden fundamental telecommunications services to offer wholly novel experiences such as immersive mixed reality and holographic and multi-sensory communication. Capacity, data rate, latency, reliability, and other characteristics of 6G mobile data communication services will continue to increase. This will boost the value of services by broadening the client base and increasing end-to-end flexibility and adaptability to satisfy the demands of people and industries.

This implies that, in comparison to 5G, every performance parameter, such as data rate, including peak data rate and user experienced data rate, communication latency, and area traffic capacity, would need to be enhanced several times or more.

The definition of 6G service capabilities requires careful evaluation of demand, technology, and cost, while balancing performance measures and efficiency indicators.

Technologies that enable

To enable the new 6G services and accomplish integration of sensing and communication, new network functions must be created. 6G will bring together mobile networks and computers, as well as cross-domain data exchange and a native AI network. As a result, a completely new system architectural design is required.

Integrating sensing and communication opens up a new avenue of possibility in cellular wireless networks: 6G native AI would improve network and air interface efficiency, increase system flexibility, and lower costs. The implementation of an end-to-end cross-layer data plane is required to provide intelligent and fundamental information services. Communication at very low power levels lowers the barrier to terminal access, allowing truly pervasive connection. Currently, some of the most exciting research areas are the evolution of Multiple-Input Multiple-Output (MIMO), Reconfigurable Intelligent Surface (RIS) technology, and new waveforms, which are paving the way towards a more efficient and flexible network that can support more application scenarios and offer more advanced sensing functions.

6G technology standards are currently in the early stages of research and development. The vivo Communications Research Institute is committed to further refining 6G scenario use cases and technical indicators, conducting extensive research and experimental verification of prospective 6G technologies, and contributing to the establishment of a worldwide uniform 6G technology standard.

New technology with live soccer game listening at Stadium

During LAFC's next home game at Bank of California Stadium, fans will be able to hear commentary from comic Will Ferrell and tennis star John McEnroe, in what is likely to be a unique experience for Gold and Black supporters. , On Saturday, August 13, LAFC will face Charlotte FC (7:30 pm). The MixHalo programme, a new technology that gives great audio in real time to the audience that attends sporting or entertainment events, may hear the comments. The programme is free to download on a mobile phone, and all that is required are headphones. Audio signals from the official LAFC narrator, Max Bretos in English and Armando Aguayo in Spanish, will also be accessible via the application for the aforementioned meeting.

"At our heart, I believe we can give a fan experience, whether it's narration at a football stadium or music coming from an audio board at a concert or a conference." "There is no latency since the audio is loud enough," said MixHalo CEO John Wars. "Around the same period, people are listening to Armando[Aguayo]audio. There is just a millisecond delay. That is really what distinguishes us. There was no way we could have done this previously. This technology has to be developed via the Internet network." Had to do it."

MixHallow, invented by Incubus guitarist Mike Einsiger and violinist Ann Marie Simpson-Einsiger, is an entertainment-related device that has previously been utilised in performances, where the audience may hear better using headphones.

"Being able to add better audio to a live event is a terrific thing, and there's some significant technology behind it," Wars added, adding that Sapphire Sport, a business that helped bring the product to the sport, was one of his major investments in this technology. for parks and stadiums

The technology first appeared at LAFC home games in May of last year. The free audio offer is valid for all remaining LAFC home games in 2022.

"LAFC is one of the most technically advanced clubs in the league, and they understand and verify our technology because they have extremely high standards and know what they're doing," the executive said.

This new technology, which is only accessible to game attendees, is already available at Sacramento Kings and Buffalo Sabres games.
