Smart Solar Street Light Applications for Cities and Municipalities

Over the last decade or so, you may have heard a lot about the many different applications of solar street lights.When you think about it, the locations fit for solar street lights are not as limited as many would suggest. People perceive limitations in solar street light applications caused by weather conditions (lack of sun) and shading.

However, the introduction of smart technology and the sheer amount of under performing outdoor lighting units together with remote areas without lights increase the potential for installation of new solar street lights or solar retrofitting.With the ongoing smartification of cities by applying new energy efficient technologies, implementation of green urban design projects and increasing demand for energy savings you can always find a diverse range of potential applications for solar powered street lights (such as public parking lots, parks, sidewalks, squares, city districts, roads, bicycle lanes and many other).As with any renewable energy product that comes onto the scene, customers are chiming in with, "Will it function longer and better than other street lights? How to achieve ROI and energy savings in the shortest period possible?"The short answer is: "Absolutely".

The longer answer? Read on to find out what are some of the main urban applications of smart solar street lights (and be sure to follow Lightinus on Facebook and Twitter for more info on this topic!).SMART SOLAR STREET LIGHTS: LONG-TERM COST SOLUTION FOR CITIESCities, Municipalities and Urban Planning Departments dwell on energy efficiency, effective transportation and communication, waste management, security and high quality of public services for citizens. In this regard, the implementation of Smart City Initiatives is perfectly aligned with the benefits that smart solar street lights bring to the table.

Introduction of intelligent technology in combination with clean energy sources results in long-term sustainability and improved public services. Modernizing street lighting infrastructures is part of many successful Smart City Projects: read the following article on 6 cities that achieved significant improvements through smart technology and green energy practices.Today, we still have over 300 million traditional street light installations which generate high energy cost and are highly inefficient, do not deliver reliable illumination, require high maintenance and high installation cost and produce CO2 emissions.

The opportunity cost of not improving public street lighting infrastructures is rising exponentially. To illustrate, 33% of all European street lights still use standards developed in the 1930s, which require costly on-site maintenance and allocation of lots of resources. According to a pilot research at city level in North America taking into account 190,000 traditional street lights, given that sodium bulbs have a life span of 5 years, the replacement and maintenance cost for each bulb is 330 USD, which means that on average the city replaces 38,000 lamps per year.

The total maintenance cost for this activity amounts to 12.5 million USD per annum.Can you imagine the savings that could be accomplished by solar retrofitting or installing smart solar street lights (either completely off-grid or solar/on-grid) in urban areas? Actually, we can calculate energy savings from using solar street lights based on the following information about your existing street light network:Purchase Price per poleInstallations Cost per poleAverage Electricity Cost per yearAverage Maintenance Cost per yearSMART SOLAR STREET LIGHTS: LED AND CLEAN ENERGY FOR BOOSTING SAVINGSTraditional street lights are expensive, typically consuming about 40% of a city's total electricity costs. Switching to LED street lights with remote control systems can provide the same amount of lighting ( even better) at just a fraction of the energy used, while decreasing significantly the maintenance costs.

Solar LED street lights on the other hand, facilitate even more the energy efficiency case for cities. They can provide the same features as grid tied LED street lights plus limitless clean energy power that will further reduce the energy costs at city level. To read more on the differences between traditional and solar street lights read this blog.

The City of Barcelona achieved 30 percent energy savings by implementing smart technology across their urban lighting system. Light on demand is the key concept in generating energy savings and increasing the optimization of your solar system. Dimming the light from 100% to 50% in late hours during the night, can make a huge difference in millions of euros from increased energy efficiency.

Motion sensors make sure that when someone walks by the street light, the LED light is again at 100% for couple of minutes. Reduction in wasting energy for light is as important as preserving other precious resources.Just as with any economies of scale scenario, it is a game of numbers - as the number of smart solar street light installations increases over the city area, the percentages of energy savings will increase and the maintenance costs will decrease.

Also, in areas without access to electric grid networks, the installation cost of new solar street light is much lower than the cost of extending the grid access for conventional street lights.REMOTE MONITORING AND CONTROL: MAKING LIFE EASIER FOR URBAN OPERATORSRemote management system is the key to always knowing what is going on with each component of your off-the-grid solar lighting system. With no remote monitoring tools in place, you would always have to send a technician to check each unit on-site and you will never have in-depth information in real-time on your system status.

The better monitoring and control you have of your solar lighting system, the more savings you will have from free clean energy.With optimized solar LED street lighting system you will experience economies of scale of light performance and higher reliability than traditional street lights, better illumination, decreased maintenance costs (no need to replace bulbs and allocate resources for expensive on-site system checks) no CO2 emissions, free energy, remote control and monitoring functions that will boost your ROI. Over a 15 year period, smart solar street lights can generate combined savings (including free energy generation, energy savings through optimization and increased light performance as well as reduced maintenance costs) between 1500-2000 USD per street light unit.

These economic benefits are followed by modernizing your public lighting infrastructure, streamlining the work of urban operators and decreasing the city's CO2 emissions. Everything you need to know about how to increase solar street light performance and reliability is available here.REDUCED CO2 EMISSIONSTake the following fact into consideration as well.

The use of electricity to drive conventional outdoor lighting leads to production of carbon dioxide. If global traditional street lights were converted to solar street lights, this would reduce global electricity consumption for lighting by more than 52%, avoiding 735 million tons of CO2 each year. The Paris Climate Agreement is seriously tackling such issues and cities are the biggest greenhouse gas emitters.

·RELATED QUESTION

Why don't hotel rooms have ceiling lights?

My hotel building is over 100 years old, so we have ceiling lights. We also need a ladder to change a bulb 11' from the floor. It can take 20 minutes for 1 bulb! This is one reason that we have changed to the longer lasting (and more economical) low-energy bulbs.

I would be delighted to have wall lights instead. Retro-fitting them would however be even less economically sound.

Higher than average ceilings mean ladders to change the bulbs in ceiling fittings, and this extends the maintenance time and convenience for staff enormously. Even normal height ceilings mean that a chair is needed to swap a bulb out. Wall fittings are so much more convenient for both staff and customers, reducing the time taken to get light again!

As Michael Forrest Jones says - anything other than a simple bulb swap requires the power to be cut to the whole circuit (which may be more than just a few rooms). This makes it very awkward to do emergency repairs after dark! -- Been there done that... Go with wall fittings that can be isolated in-room!

In short:

I have ceiling lights.

I don't like them, as they are awkward for maintenance.

Replacing them would be expensive and extremely difficult - basically a total rewire of the hotel lighting system.

Design engineers are not stupid. they note the first 2 points!

Development Direction of Solar Street Lamp Manufacturers
Development Direction of Solar Street Lamp Manufacturers
There are many solar street lamp manufacturers. In the face of fierce competition in the industry, solar street lamp manufacturers have to face some problems if they want to develop. If they want customers to find you or patronize you again, the premise is that you are a good manufacturer in all aspects, What kind of development direction should solar street lamp manufacturers have now?If the solar street lamp price has an impact on customers, it can only be that the solar street lamp manufacturer has not really succeeded. Because the price war is never an inevitable factor for the development of manufacturers. Today, you can give customers a very low price and reduce the street lamp price by reducing the Watts actually needed by customers. It may not be guaranteed that another manufacturer will use the same method to reduce the price and attract customers. You are lowering the price, and your opponent is also lowering the price. In this way, long-term development will only hurt both sides.Therefore, the price war is not the correct development direction of solar street lamp manufacturers. The correct direction should be to focus on product production, improve product quality and cost performance, and do a good job in after-sales service at the same time. It's like a 99 yuan smartphone and a Samsung phone with hundreds or even 3000 yuan. There is a big difference in price, but we still choose Samsung phone because of its high brand, good performance and cost performance in all aspects. Therefore, the development direction of solar street lamp manufacturers should not tangle in price, but do a good job in their products and improve their brand.
Industry: LED Industry Reshuffle Through Three Forces
Industry: LED Industry Reshuffle Through Three Forces
The collapse of small and micro led enterprises last year has opened the curtain of the reshuffle of China's LED industry. Since the beginning of this year, three major factors, such as the rising threshold of government procurement, the continuous tide of IPO listing and the introduction of industry standards, will accelerate the process of reshuffle in the LED industry.On March 20 this year, the "2012 financial subsidy promotion project for semiconductor lighting products" organized by the Ministry of finance, the national development and Reform Commission and the Ministry of science and technology held a domestic public bidding in Beijing, involving led downlights and reflective self ballasting LED lights for indoor lighting, LED street lights and led tunnel lights for outdoor lighting, Nearly 300 bidding representatives from 110 enterprises across the country participated in the bidding activities.The national development and Reform Commission made it clear that in 2012, the Chinese government will spend 40 billion yuan on the procurement of LED street lamps and provide 30% financial subsidies to LED street lamp users. Since March this year, all lighting projects and new planning areas invested by the provincial government have used LED electrodeless lamps in the field of public lighting, which is estimated to bring a market of hundreds of billions of yuan.Don't think that the government will "sprinkle pepper" again. An entrepreneur who participated in the bidding on March 20 revealed that the national bidding raised the threshold. For example, products should have energy-saving certification. The province also invited tenders for LED products entering the indoor lighting of public works this year. So far, downlights of 3 enterprises, spotlights of 3 enterprises, bulb lamps of 6 enterprises and fluorescent lamps of 22 enterprises have won the bid.Facing the industry pattern of "small and scattered", the government began to realize that it is necessary to support powerful enterprises to become bigger and stronger.More and more led enterprises are listed, which will become another important force for industry integration. After development in recent years, the total number of Listed Companies in the LED industry has been close to 40, and not a few are lining up for listing. It is expected to produce some industry leaders who can compete with international giants.According to the data of provincial Lighting Appliance Association, from 2010 to now, more than 100 LED projection lamp enterprises have completed the share reform, and the Pearl River delta accounts for 51.5%; The listed led enterprises account for about 61.5%, including Hongli optoelectronics, Zhouming technology, etc; There are also some ready to be listed, such as Shenzhen Jiawei Co., Ltd., which exports solar LED outdoor lights for 1 billion yuan a year, and will be listed soon.After the listing of led enterprises, it is not only conducive to establish their own good brand image in the chaotic market, but also can use capital means to acquire and merge, expand themselves and purify the market. Zhouming technology said that if it encounters a good project, it does not rule out the possibility of acquisition.The third force of integration comes from the continuous improvement of industry standards. The national standardization management committee recently held the first working meeting of the semiconductor lighting standard leading group, involving the national development and Reform Commission, the Ministry of science and technology, the Ministry of industry and information technology, the Ministry of housing and urban rural development, the Ministry of Finance and other departments. This is the first time that the industry has uniformly planned and deployed the semiconductor lighting standardization work at the national level Light source and lamps, lighting application and energy efficiency.The Provincial Department of science and technology will also announce the progress in the formulation of semiconductor lighting standards this week. At present, 130 standard items have been listed, and led enterprises can participate in the revision of industry standards through bidding.It can be predicted that with the gradual improvement of industry standards, the LED metal halide lamp industry will bid farewell to the mixed situation. In the upcoming 12th Five Year Plan for semiconductor lighting, the state pointed out that by 2015, the scale of semiconductor lighting industry will reach 500 billion yuan, and cultivate 20 30 leading enterprises with independent brands and independent intellectual property rights, and 40 50 innovative high-tech enterprises

I Would Like to Ask What Are the Ways to Improve the Brightness of Solar Street Lamps?
I would like to ask what are the ways to improve the brightness of solar street lamps?1. Determine the brightness of LED solar street lamp before purchaseBefore purchasing solar street lamps, if it is a large number of recycling, the best thing is to choose manufacturers with industrial plants and drive to the processing plant to have a look. If you decide where to buy, you must talk to the other party about the regulations on chromaticity. If you don't have much definition of this chromaticity, you can let the other party make a sample to have a look.If the requirements for chromaticity are very high, the size of LED light source should be larger. Some manufacturers will choose the most suitable scheme for you out of your own consideration. If it is not particularly bright according to your specific situation, you can also listen to the manufacturer's suggestions.2. Lower the LED solar street lamp equipmentIf solar street lamps are to be installed on both sides of the road, we should fully consider whether there are green plants on both sides of the road. Because the solar street lamp is converted into electromagnetic energy by digesting and absorbing solar energy, if something blocks it, the actual effect is undoubtedly impossible to be very good. When such a situation does occur, why not reduce the height of the solar street lamp and not completely cover the solar panel.3. Query LED solar street lamps on timeMany solar street lamp projects are not easy to hold meetings after the equipment is good, which is naturally not very good. Although solar energy does not need maintenance or cleaning by full-time personnel, it must be queried on time. The damaged position should be repaired immediately. If the solar panel has not been removed for a long time, it also needs to be inadvertently scrubbed.

This Can Be Done When the Solar Street Lamp Cannot Work (I)
This Can Be Done When the Solar Street Lamp Cannot Work (I)
1 Power loss of solar street lamp: the power loss of solar battery is due to the quality problem of the battery itself. The cheapest one is 2-3 yuan 1Ah. Generally, this is not very reliable. Problems continue to occur after using it for about a year. Therefore, to solve this problem, replace the solar battery and replace it with a better manufacturer, If it is a northern city, it should also be noted that the battery must be buried below the frozen soil layer, especially in cold places. Thermal insulation cotton should be added to the battery, because the capacity of solar energy storage battery has a great relationship with the external ambient temperature.2 The LED light source of solar street lamp is not on: it may be the most direct way for the performance of solar street lamp. The solar street lamp system is abnormal, that is, it is not on. One of the reasons why the solar street lamp is not on may also be the problem of LED light source. As a general purchaser, it is difficult to distinguish high-power LED light source. If the solar street lamp is not on, You can simply check the light source by yourself. If the system is small and the system voltage of the light source is 12V or 24V, the conventional configuration is used. The best way to detect the light source is to connect the battery directly to the light source. If the light is on, it proves to be normal.For more questions, please click the right figure to consult online customer service.
