„Advantages of solar street lights
The use of solar power for illuminating streets and other public places is getting popular day by day. It has become a dependable source of lighting streets around the globe. There are multiple benefits of using solar street lighting fixtures, like conservation of energy, use of a conventional source of energy, and less dependence on the national grid. Tropical countries that receive ample sunlight most time of the year can be highly benefited from this source of light.
These days, outdoor solar lighting solutions are powered by an in-built battery, PV panels, smart sensors, LED lights, everything integrated into one compact unit. This form of lighting option has become an environment-friendly and cost-effective way of lighting streets and public places.
As much as solar energy is a cost-effective option for lighting, using LEDs with solar light becomes a super saver combo. LED lights are long-lasting, maintenance-free, and known for energy conservation. These specifications of solar LED luminaires are perfect for lighting-up roads, streets, parks, etc.
Advantages of solar-powered outdoor lights
As infrastructure facilities around the world are getting stronger, the usage of modern solar street luminaries is increasing rapidly. It is because these lights come with inbuilt lithium-ion batteries, embedded solar panel, night and motion sensors, battery management system and automatic controls.
Some other notable benefits of solar street luminaires are mentioned in the pointers noted below:
● Solar street lights are water-resistance and weatherproof and have a low glare and low insect attrition rate.
● The solar panels in these lights convert solar energy into electrical energy that gets stored in the inbuilt battery and is utilized for dusk-to-dawn lighting operations.
● The main feature of contemporary solar street luminaires is the battery management system which aids the presence of motion and night sensors.
● In the first five hours of the night, the performance of the system is up to medium-level brightness. The intensity of light decreases progressively until dawn or till the time the PIR sensor is activated by the movement of humans.
● With a smart lighting option, it automatically turns on to full brightness when it senses human movement within a specific radius of the luminaire.
● In comparison to conventional street lights, solar outdoor luminaires require almost no maintenance.
These unmatchable and smart features of solar LED street lights allow people to rely on this type of luminaires. Trusting SolarRISE LED by Wipro Lighting can be advantageous due to a number of benefits like high efficacy SMD LED with secondary lens optics for uniform street lighting distribution, constructed with high-efficiency monocrystalline silicon photovoltaic panel, and many more.
Common Myths about LED Street Lighting
The potential effects of LED street lighting on health and the environment have been a hot topic of discussion over the last year. As this conversation has evolved, so too have many misperceptions and mischaracterizations of the facts on LEDs. We’ve assembled an array of helpful resources on the topic to help shed some light and are clarify some of the most common myths on LED streetlights.
LED streetlights are no more harmful to humans and animals than other kinds of streetlights. The concern is not the type of light source, but the amount of emitted light that falls in the short-wavelength, often referred to as the “blue” part of the spectrum. And, unlike other types of streetlights, LED streetlights actually offer the potential to control the amount of short-wavelength light that they emit.
On the contrary, short-wavelength light is a fundamental component of the natural world. It’s present in sunlight and has been shown to play an important role in a number of physiological processes, such as affecting circadian rhythm (our 24-hour “biological clock” that controls sleep/wake cycles). The concern is that too much nighttime exposure to short-wavelength light may disrupt sleep patterns and have other undesirable effects.
It’s true that early LED lighting products tended to have greater levels of short-wavelength content because the technology was still in its initial stages of development. Tremendous advances since then, however, mean that today’s LEDs can be designed to emit as little, or as much, short-wavelength light as desired, without excessive drop-off in efficiency or other aspects of performance. LEDs also offer much greater control over where the light falls. This means they can often meet the same illumination requirements as conventional streetlights while emitting much less light – thus reducing even further any short-wavelength content.
Most street lighting situations benefit from having at least some amount of short-wavelength content. Short wavelengths are a key component of the visible light spectrum, with benefits ranging from aesthetics to safety. White light sources that contain short wavelengths, for example, can show the colors of objects more naturally, aid in identification of people and objects, improve the contrast between an object and its background, and enhance peripheral vision at the low levels of illuminance that typically characterize street lighting.
Can I use Indoor Lighting Fixtures Outdoors?
There are hundreds of fixtures available for indoor and outdoor use. But the two are not interchangeable. It is usually safe to use an outdoor lighting fixture indoors. However, most indoor lighting fixtures are not suitable or safe for outdoor use. The best way to tell if a light fixture or bulb is safe to use outdoors is by checking its UL rating. So proceed with caution if you plan to use indoor lighting fixtures outdoors, as most indoor fixtures are for indoor use only.
When you go looking for lamps (that technical term for bulbs) and lighting fixtures, look for a UL listing or rating. UL (formerly Underwriters Laboratory) is a testing and certification agency that certifies lamps and fixtures among many other industrial and commercially available products. A UL listing or similar certification is required by law for many products.
There are several grades of UL ratings that help indicate the proper setting and use of an electrical component. When used according to the appropriate UL rating, electrical products should be safe to use and operate. However, using an electrical component in a way that is outside of its UL rating can cause the component to fail. It may also create a fire or other safety hazard.
The most basic UL certification is “UL Listed for Dry Locations”. Often this is listed on packaging simply as “UL Listed”. These items are safe to use indoors. However, they should not be exposed to any type of moisture. This is the ideal listing for dry areas of the home such as living rooms, kitchens, bedrooms, and any other area that is not exposed to the elements and is not normally subject to excessive humidity or condensation.
A lamp or fixture that is UL Listed for Dry Locations should never be used in a damp or wet location. Using a lamp or fixture listed for dry locations outdoors could cause a lamp to fail. When exposed to the elements, these lamps and fixtures are not built to be watertight or even water resistant. The introduction of water can cause the lamp to malfunction. The most benign malfunction would be for the lamp to simply stop working. However, there is a greater danger.
A lamp or fixture listed for dry locations that is used outdoors can become a fire hazard. When exposed to the elements, water can get into the fixture and ultimately into the lamp, causing leakage current. Leakage current occurs because water conducts electricity. When water comes in contact with electrical components, the current runs from the exposed electrical components through the water. The current running through the water can create heat or cause arcing, which can ignite combustible materials. This kind of electrical fire is a common cause of house fires.
The light-emitting diode (LED) is today’s most energy-efficient and rapidly-developing lighting technology. Quality LED light bulbs last longer, are more durable, and offer comparable or better light quality than other types of lighting.
LED is a highly energy-efficient lighting technology, and has the potential to fundamentally change the future of lighting in the United States. Residential LEDs — especially ENERGY STAR rated products — use at least 75% less energy, and last up to 25 times longer, than incandescent lighting.
Widespread use of LED lighting has a large potential impact on energy savings in the United States. By 2035, the majority of lighting installations are anticipated to use LED technology, and energy savings from LED lighting could top 569 TWh annually by 2035, equal to the annual energy output of more than 92 1,000 MW power plants.
LED lighting is very different from other lighting types such as incandescent and CFL. Key differences include:
Light Source: LEDs are the size of a fleck of pepper, and can emit light in a range of colors. A mix of red, green, and blue LEDs is sometimes used to make white light.
Direction: LEDs emit light in a specific direction, reducing the need for reflectors and diffusers that can trap light. This feature makes LEDs more efficient for many uses such as recessed downlights and task lighting. With other types of lighting, the light must be reflected to the desired direction and more than half of the light may never leave the fixture.
Heat: LEDs emit very little heat. In comparison, incandescent bulbs release 90% of their energy as heat and CFLs release about 80% of their energy as heat.
Lifetime: LED lighting products typically last much longer than other lighting types. A good quality LED bulb can last 3 to 5 times longer than a CFL and 30 times longer than an incandescent bulb.
LED lighting is available in a wide variety of home and industrial products, and the list is growing every year. The rapid development of LED technology has resulted in increased product availability, improved manufacturing efficiency, and lower prices.
Eco-consciousness is on the rise in Singapore, and the government, businesses and individuals are realising the importance of adopting sustainable practices.For instance, Singapore will very soon become home to the world’s biggest floating solar farm, which is expected to produce enough power for 16,000 4-room HDB flats. What is more, the HDB is greening the public housing sector through the Green Towns Programme, which aims to reduce energy consumption in HDB towns by 15% in 2030.As individuals, one way we can make our homes more eco-friendly is to use green electricity, which is electricity generated from renewable sources. While some are happy to make the switch to green electricity providers, others look to installing solar panels into their homes.For those who are interested in having their own home solar panels, we asked Solar AI Technologies to find out more about this option.
Pros and Cons of Installing Solar Panels In Your Home
Before jumping into the installation process, here’s an overview of the pros and cons of installing solar panels in your home.
When exposed to the sun, solar panels capture light particles in order to generate voltage or electricity. They thus offer a cost-effective way for households to supplement their electrical supply and lower their electric bills. There is, however, a misconception that solar-powered homes experience electrical supply disruptions at night.“In Singapore, all houses with solar panels are still connected to the electricity grid. Homeowners can sell excess electricity generated in the day to the grid and will not experience any electrical outages. There is also no need for battery storage to supply electricity at night,” says Solar AI.So even on rainy or cloudy days, you’re not at the risk of experiencing electrical outages at home.
The short answer is maybe.The long answer is that your home first consumes electricity generated by your solar panel system, for which you will not have to pay electricity bills. After that, if you still require additional power, electricity will be drawn from the electricity grid. You will pay your electricity retailer for this electricity.What if your solar panel system generates more electricity than you use? Any excess electricity is sold back to the electricity grid and can be used to offset your electricity and other utility bills.Still, the end result is you’ll pay less for your electricity since you’ll likely consume less electricity from the grid.
