Solar panels for Solar led street light(Classic) generate electricity during the day. The control electronics know when the solar panel is generating electricity and feeding it to the battery assembly. When the sun goes down, the panel produces less and less power, and once the specified threshold is reached, the manufacturer will pre-determine that the controller will switch and the light will turn on.

At dawn, as the sun rises, the group begins to generate electricity again. This triggers the control electronics to make another switch to turn off the light and again begin feeding the generated power into the battery assembly. Repeat the process daily.

If adaptive lighting control or time-sharing operation is being used, the system is set to dusk at the factory after dusk and x hours before the dawn operation, with operations between them being reduced or turned off. Once the system is installed, it knows when the twilight will occur and then guesses at dawn. However, quickly learn the actual dawn time. For the system to run flawlessly, it only takes one or two nights or two controllers to know the exact time of the dawn to see when the system should work.

Commercial solar lighting and solar systems have a long life if they are properly sized. Each component has a different life span, but as a whole system, Solar led street light(Classic) should last for 30 years or more and be properly maintained. Let's review each component and analyze how the system should run for more than 30 years.

Solar battery

Solar lighting and off-grid power systems use two types of batteries, GEL cells, and lithium ions. GEL batteries are the most common lithium-ion battery that is on the market. Each battery has its pros and cons; however, we will introduce the life of the GEL battery here, as this type of battery is proven in the field of lithium-ion batteries that are still new to gaming.

If the size is right, the GEL battery should be available for 5 to 7 years on site. The depth of discharge in cold weather must be considered so that the number of cycles is kept within this range. Since cooling can degrade battery performance, additional autonomy should be included so that the system does not use more than 20% of battery capacity per night and has the solar capacity to fully charge the battery.

LEDs and lamps

LEDs are growing as fast as any other electronic device. A few years ago, you could expect an LED light to run for 50,000 hours, but today you can get 100,000 hours or more. This is more than 20 years of application from dusk to dawn.

Over the years, the fixture housing has also been improved. As powder coatings and painting methods and materials improve, the fixture itself should be as long as the LEDs inside it.

Solar panels

Solar energy is still the longest life of any component. Solar panels are typically guaranteed for 20 to 25 years and have a life span of more than 30 years. Since there are no moving parts or anything that can be replaced, you can install solar panels and forget about them, but be sure not to block them.

Installation and hardware

Most companies today use aluminum as a stand and stainless steel as hardware. This allows the system to stay in coastal and other harsh areas without rusting or worsening. If standard steel is used, the mount and hardware cannot withstand the weather even if it is coated with powder. If aluminum and stainless steel are used, they should last for 30 years or more.

As you can see, commercial-grade solar lighting and power systems should last for quite some time and require little maintenance. Taking these factors into consideration when making your initial purchase will ensure that you get a system that will stand the test of time and provide a good return on your investment.

The excellence of LEDs makes LED street light an ideal choice. Adding solar energy technology and becoming a Solar led street light(Classic), the carbon footprint is further reduced after the street light is completely out of the grid. The efficiency is increased by a factor of two, and even electric power is not required to generate light, and AC power loss does not occur.

Converting a standard street light into a more efficient solar led street light can have a major impact. Removing a large number of street lights from the grid and powering them through solar power will save money and time. Our city will change when local streets and highways adapt to LED lighting technology.

LEDs can use valuable resources wisely. Energy consumption is very low, using only a small fraction of the traditional street lighting. The LED uses only half the power of a fluorescent lamp, one-fifth of an incandescent lamp and one-third of an HID lamp. LED lights provide about 100 lumens per watt and distribute light even where needed, rather than unnecessarily scattering light in different areas.

LED street light emit whiter light. The LED light source has a high CRI or color rendering index that provides the illumination closest to natural light. Streets become safer, and for drivers, pedestrians and cyclists, the road can be seen more clearly because black spots or shadows are eliminated.

What prevents the city from implementing a new outdoor lighting system? Guess it. My answer is first of all budget constraints.

However, if Solar led street light(Classic) are part of a smart city development plan, this should not be a problem. Since solar led street lights are powered by off-grid solar power, the city's electricity costs will eventually decrease. The energy savings from installing a solar streetlight system will enable new funds to implement many other applications that complement the smart city concept.

Does the modern feature of solar led street lights cause more harm than good?

Although this is true for some technological innovations, solar led street lights have a little negative impact on the environment:

Since the sun's energy is used to power the system, there is no natural resource exhaustion.

LED lamps emit less carbon dioxide than conventional globes.

The entire solar off-grid lighting system will reduce emissions and thus reduce pollution.

Solar street light poles do not require a grid connection. This, in turn, reduces construction and installation procedures, thereby reducing the risk of affecting flora and fauna in the area.

If you're like most people, don't think too much about Led Public lighting(Classic), but these public lighting designs make roads safer, and the streets have been safer over the past decade. During this time, efficiency improvements were slow and steady, and contrast and visual acuity related issues were repeatedly considered and addressed in research and improvements in LED technology.

Over-illumination is related to luminaire design and requires ideal positioning, location, and a number of fixtures for a given project. Many organizations have developed new test methods and developed more stringent performance standards, leading industry experts to observe that LED public lighting is expected to be more than expected for high-intensity discharge lighting.

One thing that makes LED public lighting very flexible and capable is that it can be controlled to such a high degree. LED public lighting can be managed not only by simple dimming control but also by complex controls such as motion sensors, photoelectric sensors, and timers. In addition, it integrates with network interfaces, complete software programmability, and wireless communication back to centralized systems.

This is the main reason why municipalities, federal regulators, energy service companies and utility companies have reached the same conclusion. Control is one of the most important aspects of modern LED development and design.

However, implementing these controls in a cost-effective manner is not without challenges. The LED market is booming and new opportunities are open, such as the Internet of Things (IoT), artificial intelligence (AI), smart city and machine-to-machine communication. For all involved in the LED industry, an important directive is to maintain an open communication line and properly disseminate information about emerging technologies that may be relevant to current and future LED public lighting.

When you think of outdoor Led Public lighting(Classic) projects, you may not realize that municipalities should implement such concepts at least as much as residents and businesses do. LED public lighting have much to offer cities across the country and around the world. In fact, various places are leading the way at making use of this modern type of lighting, and we can expect other areas to follow suit.

LED public lighting: Helping Cities to Curb Expenses

Cities are making the switch to LED public lighting for a variety of reasons. One of the top motivating factors is cost. LED public lighting options yield increased cost savings over their lifetime of use. In addition, network-controlled lighting offers municipalities the capacity to remotely adjust streetlights, providing another way to cut energy costs overall.

Increasing Energy Savings

While slashing energy bills is certainly reason enough to install LED public lighting, the reduction in energy output is also critical. To minimize environmental impact, cities across the globe must do everything within their power to expend as little energy as possible. Los Angeles, for example, has undertaken a project to replace the old, incandescent bulbs of the past with energy-efficient LED public lighting. Since starting this endeavor, the city is now consuming well over 50 percent less energy than it previously did. This has also yielded Los Angeles a savings of more than $50 million.

Making the World Safer

Another top advantage of employing smart technology is the potential for creating safer spaces. In Chattanooga, Tennessee, smart streetlights have been used to combat the prevalence of gang violence. How does this work? Because street gangs (and criminals, in general) have a tendency to gravitate toward unlit areas to perpetrate crimes, LED public lighting serve as an invaluable resource. By brightening locations (such as city parks) known for sustaining criminal activity after dark, local police departments can offer a notable deterrence to those who might otherwise engage in breaking the law.

The following is an example of a simple financial return formula for Led Public lighting(Classic) (for reference only):

Replace 1000 100 W HPS Cobra Street Light with R0,60 energy per kWh.

Initial investment cost:

The cost of LED public lighting = R 2300 x 1000 = R 2 300 000.

Installation cost = four lamps per person per hour R400, two people per person for two hours: R400 x 250 hours = R 100 000.

Bid, management and miscellaneous expenses: R60 000.

Total initial cost: R 2 460 000.

Annual savings:

Energy savings per year: 1000 street lights x 4000 hours per year x 100 W x kWh per kWh R0, 60 = R 240 000.

Annual maintenance savings: 1000 street lights per year to save R400 per lamp (assuming HID field replacement, cleaning, replacement of igniters, ballasts, photocells and other lamps for four years with LED 10-year cleaning cycle and occasional photocells And drive replacement) = R 400 000.

Total annual savings: R240 000 + R400 000 = R640 000.

Simple return on investment: R2460 000 / R640 000 = ±3,84 years.

Often, plans with a payback period of no more than five years should of course be completed and will typically be delayed for more than a decade. However, due to the urgency of global climate change, many communities, especially those based on fossil fuels, are even implementing energy-saving plans with long payback periods. If the return on investment seems to be favorable, a more rigorous financial analysis may be needed to determine the return on investment and the net present value (NPV) of the project.

Today, while more and more cities recognize the value of Led Public lighting(Classic), there are still financial and organizational barriers to be addressed, including:

Finance: Although the energy savings from LED public lighting upgrades have been well documented, for many cities, it is still a challenge to approve financial plans to make the necessary up-front investments. The practical advantages and long-term cost savings of deploying intelligent controls while upgrading to LEDs are not always easy to adapt to existing procurement and financing methods.

Customer understanding: A lack of understanding of new lighting technologies can also be a barrier to adopting LED and network solutions. Although the LED lighting market is overcoming this obstacle, its control is lagging behind because customers are not familiar with these technologies. The problem is not quality, but the lack of understanding of the business case of the additional benefits of LED public lighting, especially for secondary applications.

LED public lighting owned by utilities: In the case of public utilities providing public lighting, a business case for establishing energy efficiency may depend on incentives set by the regulator. This means that some utility companies are reluctant to invest in lighting network upgrades. However, attitudes are changing due to the pressure to reduce carbon emissions and the use of street lights as a source of assets and potential revenue. In fact, many utility companies now view public lighting as a pathway to a range of new service offerings, while they are also looking for opportunities in the energy cloud.

In many cases, Led street lights Manufacturers(Classic) can block or reflect glare by integrating the lampshade into the luminaire. Allows non-cut-off luminaires to produce an unlimited amount of light pollution and glare, but they are used primarily in urban areas such as shopping streets and parks. Even if the glare is well controlled in the lamp, it should be noted that if the lamp head is tilted to direct more light to the street side, glare and light pollution are increased. This can be prevented by using asymmetric beam optics designed for the lamp and mounted in parallel with the street.

Glare is regulated by cut-off classification and glare index level, and in many highways, it is adjusted by threshold increment (TI percentage), which calculates how the driver experiences glare while taking into account the adapted level of illumination.

The glare that exceeds 90 degrees upward is considered to be light pollution. Wasted light can lead directly to the road, not the sky or the bedroom window nearby. The North American Institute of Lighting Engineering (IESNA) divides luminaires into four different cut-off categories, from non-cut to full cut. The category is defined by the relative maximum peak intensity in the glare range, the vertical angle from 80 degrees to 90 degrees, and the relative peaks in the skylight range of 90 degrees and above. Due to the many lens optics and luminaires with spherical protective covers, some stray light may appear, making it difficult to achieve the most desirable full cutoff classification, which is becoming an increasingly common requirement today.

Before the Led street lights Manufacturers(Classic) begin to discuss, first check to see what happens on top of the head. In this nationwide street overhaul, softer high-pressure sodium lamps are being phased out to facilitate brighter light-emitting diode (LED) lights.

The price of LED street lights has dropped enough to make them an economical upgrade that is more efficient and lasts far longer than traditional street light bulbs. They can be used for 15 to 20 years - in some cases 4 times longer than older bulbs - and durability also reduces the need for manual maintenance. They also consume less power. Small towns “saving more than $57,000 in annual energy costs,” while big cities like New York can save $14 million a year – “an energy cost of $6 million and a maintenance cost of $8 million.”

But AMA believes that the lights may be too bright, "causing night glare is worse than traditional lighting," the doctors said in a statement issued in June that AMA uses community guidance to reduce the harmful effects of high-intensity streets on humans and the environment.
