How Much Do You Know About Waterproof Performance of Outdoor Solar Lights?
Solar-powered lights that installed outdoors usually need to withstand the test of various bad weathers such as heavy rain, snow, frost, which is possible from time to time. If the waterproofing measures of solar lights are not in place, the water will penetrate the interior of the lights and corrode the internal circuit, resulting in a lighting failure, and the service life of solar lights will also be shortened. Therefore, taking the waterproof performance into full consideration is quite necessary before choosing solar powered lights outdoor. Today, we will share some knowledge about the waterproof performance of solar powered landscape lights outdoor.At present, the waterproof technology of outdoor led lights is mainly divided into two directions: structural waterproof and material waterproof. Structural waterproof means that it forms a waterproof structure after all parts of the item fitting together. And material waterproof is to reserve the position of sealing glue to seal electrical components during product design, and use glue material to make the electrical components completely airtight and thus realize waterproof function during assembly.With the development of waterproof material technology, the special potting glue for various types of LED lights from various brands continue to appear, for example, modified epoxy resin, modified polyurethane resin, modified organic silicone, etc. Different chemical formulas have different physical and chemical performance indexes on elasticity, molecular structure stability, adhesion, UV resistance, heat resistance, low-temperature resistance, water repellency, and insulation performance of the potting compound. The waterproof performance of the solar landscape spotlight is finally judged by its IP rating.The IP (Ingress Protection) rating of LED lights is the protection level of the light against solid (dirt, dust, etc.) objects and liquid (water). There are two numbers on the IP protection level. The first number (0 to 6) is fixed in the IP protection level. It shows resistance to solid objects. The second number (0 to 8) means a waterproof level. The larger number, the more waterproof.The most common wireless solar powered landscaping lights on the market are IP65 waterproof LED lights. They provide maximum protection for solid particles and have a certain resistance to liquid particles due to the silicone sealing washer. However, if you want to fight more extreme weather outdoor, you need an outdoor light with a higher waterproof level, that is IP67 waterproof outdoor light. They add a gluing sealing treatment based on IP65 to make the light completely sealed. Even if immersed 1M deep underwater, the lights are still able to work normally.LITOM outdoor solar landscape spotlight is exactly the representative of IP67 waterproof technology, having super-priority in waterproof function during outdoor use.Extreme weather is the main reason that your solar lighting needs to be IP67 waterproof. The surface temperature of the outdoor solar lights in summer can rise to 60℃, ultraviolet rays have a destructive effect on the protective coating of the shell, plastic parts, potting glue, sealing rubber ring adhesive strip, adhesive, etc. After a long time, there will be aging cracks, which will damage the waterproof performance of the solar lights; The temperature in winter can be reduced to minus zero, the plastic parts become brittle, and they are easy to crack under the pressure of ice and snow, which seriously affects the airtightness of the lights.Solar lights exposed to the outdoor environment need to withstand the various extreme weather above, which is why you need to choose the outdoor solar lights with a higher waterproof level reaching to IP67, just to keep the outdoor lights running in good performance even in high heat, storm, and snow days. The more waterproof, the longer service life.Summer camping is always pleasant, giving people a wonderful chance to close to nature. But do you know what is the essential equipment that you must take out for summer outdoor camping? It is solar lighting. As lights can help boost the ambiance as well as providing illumination. Life is no more wonderful than all family members sitting in front of the tent at night, talking and laughing, with lighting surrounded, very romantic.However, summer is always rainy, your solar lights for outdoor camping need to be waterproof enough. Nobody wants the wonderful atmosphere to be interrupted by a sudden power-off due to water flowing into the interior of the light and causing a shortcut. So, choose a solar spotlight with higher IP rating.

When the base voltage is greater than the emitter voltage, the current (Ic) flows into the base. Assuming the current gain to be B, the current flowing into the collector is B(Ib).Mathematically, Ic=B*Ib.Ohm's law says V=IR. So the resistor must drop the voltage. How much voltage does it drop? Here, the transistor is supposed to work on saturation region. Meaning the collector-emitter voltage (Vce) is lowest possible. So almost all (but not all) voltage is dropped across the resistor. What you are left with is very little voltage at collector. And this is where the output is taken from. Lets look at next scenario. If there was no resistor between the collector and the Vcc, the voltage drop must be provided by the transistor. You have Vcc at the collector and 0V at emitter. The transistor must drop all the voltage. Your output would always be high no matter what you provide at the input.simulate this circuit - Schematic created using CircuitLabDo we need CFD for GATE exams?No, CFD is not in the syllabus for GATE Aerospace-2017.GATE is mainly for assessing your basic engineering knowledge.

Solar String Light for Quality Solar Lights
The introduction of solar string lightWe have seen string lights in a variety of different forms, but solar string lights are pushing the boundaries in terms of size and power.Tips for solar string lightThe sun and the solar string light are the two most common avenues for solar energy. Unfortunately, there are few ways to attract some of their beams to your house and thus have them multiply in your room or living space.There are several ways to do it. One is to put some solar lights on a tripod or wall mount, hang them from the ceiling, let them shine on your wall and let any other light rays bounce off of that surface for a while. The other option is to make it look as if you've just got a new light bulb but with much better efficiency. It's similar to putting a blacklight in front of your window blinds so that they can create shadows in front of them.How to use solar string light?Solar string lights are a new trend in the realm of lighting. They can be found in many different shapes, sizes and colors. The newest ones are solar powered too, so they don't require batteries anymore. You can create different kinds of light with them and see it as your own cosmic creation.The specifications of solar string lightThe solar string light was invented in the year 2001 by an American, Gary Fadness. It is a small lamp that looks like a string of beads.The product instructions of solar string lightIn the past, solar string light was commonly used in homes. It was a new technology that could be easily integrated into a home. The main advantage of it was that they were affordable and easy to install.The product instructions of solar string lights are simple and straight forward and can be easily understood by everyone. The manual makes it clear on what to do, how to do it and why you should do it. As a result, they could help keep people away from committing technical errors when they are installing the lights in their homes.The application of solar string lightIt is a light source that uses solar energy to generate electricity. It is used in various applications, such as security monitors, portable devices and lighting.
Leapfrogging to a Renewable Future.
The devastating typhoon that hit Mozambique in March 2019 gave terrible support to the widespread expectation that poorer nations will suffer from the impacts of climate change most. The reasons include poor infrastructure, the absence of social safety nets, limited financial resources, and often tenuous public order. Poor rural dwellers depending on subsistence agriculture can not count on crop insurance or government bailouts. Floods and storms add to the pain from water and insect-borne diseases, which are likely to increase and spread to new areas.As the challenges from climate change mount, building resilience to its negative impacts may be more important than trying to get the world's poorest nations to cut back their emissions. The nations of Africa, in particular, have contributed little to anthropogenic climate change, and it's quite possible that Africa will move forward with continued low emissions, especially in the realm of electrification. Climate Change and Renewable ElectrificationAfrica has the opportunity to leapfrog the carbon-intensive centralized development process and move straight into distributed electrification — especially through on and off-grid solar and wind power. The International Renewable Energy Association (IRENA) estimates that 60% of Africa's electricity needs could be met through renewable off-grid solutions.Indeed, the majority of renewables development is now taking place in non-OECD countries. In 2017 this amounted to 94 GW of installed wind and solar globally — twice what was built in new coal plants that year.As electricity continues to spread, Africa would surely benefit from its own green new deal. But there's a real need to develop a trained workforce to fill the gap in skilled labour in the clean energy sector, to take on the skilled work of developing, building, and maintaining solar and wind projects, microgrids, and storage and local distribution systems, for the hundreds of millions of Africans who still lack access to electricity. Of course, as electrification penetrates further, it opens up many more new opportunities in a wide range of businesses, including IT, communications, and remote work.To now, most renewables development has taken place in wealthier African nations like South Africa, Kenya, and Uganda, and most commerce is happening in the cities, again among wealthier Africans. Not surprisingly, business is going where the money is. According to Gogla — the global association for the off-grid solar energy industry — most sales of off-grid lighting are similarly concentrated in Kenya, Uganda, Ethiopia and Rwanda.That means that for now the poor rural populations are largely left out, even while they could benefit most from even the most basic of off-grid technologies like lighting. Gogla notes that families with solar systems very often see an increase in income, while small businesses find new opportunities for efficiency and customer service. In addition, solar powered lighting expands opportunities for income generating work and education at home.Local clean energy systems can also help build individual and community resilience, particularly by providing water for drinking and irrigation. And they have a positive impact on health and cleanliness, by reducing indoor air pollution from kerosene lamps and improving access to clean water, communications, and health care. Putting the Leap in Leap-FrogSo the question is, how are poor communities going to gain access to these beneficial technologies? How are they going to be financed and built? And how can this be done without imposing the trappings of multilateral debt and the spectre of privatization, austerity, and neocolonial exploitation? How, that is, can the world's poor reap the benefits of an autonomous energy modernization leap-frog?Well, businesses are not entirely asleep at the wheel, and the growth of pay-as-you-go has gone a long way to proving the benefits of clean, modern energy. Gogla represents 130 firms, most of which it seems are using a PAYG model. PAYG grew at an average annual rate of 140% between 2013 and 2016, and was the model used with 80% of solar home systems sold in 2016, according to the World Bank statistics. But the very poor are still generally seen as too high-risk, and high cost (i.e. in reaching scattered rural villages) to be attractive for traditional entrepreneurs. These markets are often left to charities like Solar Aid, founded in 2006 to provide access to solar lights in Uganda, Malawi and Zambia, and to help catalyse solar markets and eradicate the kerosene lamp. SolarAid's charity work is largely educational, and the corresponding high cost of sales is what turns for-profit companies' attention elsewhere. SolarAid's "teams travel thousands of miles — spending days with local community members — sometimes only selling a handful of lights. Because that's what it takes to help people leave the darkness behind. "Another novel approach is SolShare, a Bangladeshi start-up that is developing local micro-grids "from the bottom up," to enable the 3-5 million solar-powered homes there to trade electricity, even with neighbours who do not have their own solar panels. This a truly localized peer-to-peer trading within the "last mile" of power distribution infrastructure. The SolShare network also generates a potentially valuable set of data on production and consumption patterns, and on how such a trading system functions. AfricaGreenTec (see images) is another group that provides electricity — and with it, clean water and internet connectivity — to whole villages. The key is their portable Solartainer — a solar power plant that unpacks like a high-tech butterfly from its shipping container cocoon.While bringing all the benefits of distributed solar to some of the poorest and most remote communities on the planet, AfricaGreenTech, SolShare and others also hold the seed of a much bigger shift. The next leap: Data-Driven TokenizationFor some months I've been working with innovators at Freeelio, especially around TheSunProtocol and the Electraseed Fund. These projects are creating ways to expand rural renewable electricity, and make it self-sustaining, through the application of blockchain technology and the drive of data valuation.While SolShare and Africa GreenTec have shown how power can be provided, Freeelio sees an opportunity to use blockchain and the token model to build incentive structures that enable autonomous social development through a meritocratic token distribution. TheSunProtocol, for instance, not only sees tokens being used to purchase electricity, but also aims to reward consumers for their productive electricity uses — amplifying, if you will, the economic returns on their activity.TheSunProtocol token provides a redeemable means of exchange, as its value (in kWh) remains constant. The token can be separated from the electrical supply; users could use the tokens to pay for a haircut or groceries, while their merchants could then exchange the tokens for electricity. The token could even be used in exchanges between users in separate villages, thus building an economy of value harnessed from the sun itself. This would be a leap far beyond what typical development experts typically prescribe, and reflects a far more sustainable economic vision for the future — one in which environmental and social values are reflected in something like a Quality-Adjusted GDP.Such a leap requires a takeoff point, and for now, that means the hardware, the education, and the technology development, needs to be financed, and that demand falls on donors or investors from wealthier nations. How can it be made easier for such investors and donors to be part of these initiatives? One of the big and quite reasonable concerns of financiers is in ensuring that the money they invest is achieving the returns they set out to achieve, whether these be monetary, or in the social and environmental sphere (ESG). Smaller or distributed projects are less "bankable" in part because the money can be hard to track, and the returns difficult to measure and capture. They also carry some risk (not absent from larger projects) of money being misdirected or connected with criminal activities, especially if KYC regulations have not been followed through the entire flow of funds. It's here that the ElectraSeed Fund can allow blockchain and especially smart contracts to shine. As an energy data-driven investment platform, the ESF invests in a pool of solar energy assets worldwide. It too uses smart contracts to improve data integrity and transparency, and to thus open up the scope of positive impacts for donors and investors. ElectraSeed Fund smart contracts can track investment funds down to the individual user and kWh. They may even be able to characterize the use of the kWh — in other words, the specific sorts of activities the electrical gifts support.The Electraseed Fund is thus designed to enable investors to see precisely how their investment is performing, especially in the ESG calculus, even while the Fund pools investments across a range of projects to reduce risk. Companies that seek to offset carbon emissions, or that want to verifiably achieve targets within their own ESG commitments, can access secure data on the results on the ground, half a world away, in real time.The Electraseed Fund is building relationships with host-country entrepreneurs like SolShare, to help ensure local uptake and reliability. Meanwhile it's engaging with western firms looking to build their ESG returns, and that want to find ways to better validate their investments. Another interesting model, called Energy Solidarity Token, entails the western company donating cost savings achieved through energy efficiency measures to purchase electricity to give away through the SolShare model. This allows the firm to leverage its investment to achieve environmental and social goals where they are most needed.Blockchain and decentralized renewable energy constitute a major leap for electrification among the world's poor, but the path ahead is promising. While the footprint is still small, it suggests huge potential to improve lives in Africa and South Asia, where hundreds of millions still lack electricity.A leap like this might not ultimately do a lot to reduce emissions or slow climate change, but these initiatives can make a big improvement in the lives of the world's poor, who in any case need to figure out how to live under changing climate conditions. Electricity, clean water, and communications connectivity are key elements of a resilient local infrastructure, and a radical localization - not just of energy but also food, water, and economic and commercial infrastructure - may well be what it takes to ensure rural Africans and others can continue to create and produce, to thrive in the pursuit of their goals, and to grow with their families and their communities.

Leave a note in the forms for the research venture TheSunProtocol, pilot of Electraseed Fund, and Energy Solidarity TokenThe Advantages of Solar LightingLarge companies and homeowners alike enjoy the many benefits that only solar lighting can provide. Solar lights are ideal for areas that are off-the-grid, where energy is costly or if the company is looking to showcase their eco-friendly approach to energy. Installing solar lighting is considered one of the most cost effective projects to date as they do not require trenched grid power and the actual costs of installation are minimal. There are many ways to take advantage of solar lighting solutions. Some are as small or simple as a singular LED bulb or a solar lantern, while others are more advanced needing a battery and integrated panel. These lights are generally employed to light driveways or even 150′ spaces with floodlights. Solar is the best option when power is not available in a location or too costly to install. Using solar lights also eliminates concerns around a power surge. Of course, there are numerous advantages for choosing solar lighting over traditional methods. Great Way To Go Green! Solar power is the number one source of renewable energy; therefore, solar lighting is a great way to transition to going green. It takes absolutely nothing from grid power and is naturally produced. The LED lighting uses a battery that charges up on solar power during the day, and at night it dips into the power supply to illuminate the desired area. This is a process that repeats daily without using any other form of energy. Installation is considered low cost, in any case, lower than trenching grid power. There is no underground running conduit to the light poles like you would see with traditional power, however, poles, albeit much taller, are still employed in a safe manner. Installation is safe and not as difficult as it is considered low voltage power and the only wiring is located at the top of the poles. In some instances, it may carry across to nearby poles. Standard electric trenching is rife with difficulties, but that is not something experienced with solar power installation. The greatest thing about solar lighting is that it's virtually maintenance free. This is especially the case as LED bulbs last for 20 years or more. If properly installed, the system's batteries will need some maintenance only every 5-7 years. Visually checking and cleaning the glass grid is also recommended to prolong its lifespan along with checking the light fixtures themselves. Most other components can last 30 years or more without any maintenance whatsoever. The most convincing aspect of solar power is the ability to reduce energy bills to zero. Though a commercial system can cost a lot of money upfront, the savings by utilizing solar power will pay back dividends on this investment. In addition, commercial systems also receive significant monetary incentives to make the switch to solar energy. If you care about the environment and wish to reduce your footprint, solar lighting is a great option! It works just as well as traditional power while cutting your energy bills down to zero and providing a constant stream of LED lighting. Whether you have an expansive backyard or a large area in need of illumination, solar energy is here to help. Do you have other alternatives you like for your lighting needs?
