Why choose Solar Powered LED Lighting System?
Click Volume:0

Solar powered LED lighting systems is a system which is made of a photovoltaic panel to collect sunlight and transform it into electrical current. The current goes through a controller that charges a storage battery. it is free and no electricity bills through whole year. It is a 100% green energy saving system. The solar powered LED lighting system offers a solution for areas where grid availability is weak and roads are poorly lit. In some remote regions, especially in the mountains, have roads that need lights and roads are mostly not equipped with electricity poles.

 

Solar Powered LED Lighting Systems are an efficient means to provide lighting without the need for standard utility power. Every system provides cost savings by eliminating the need to trench standard electric wires for installation or in areas where existing utility lines do not exist. These commercial outdoor solar LED lighting systems feature a long life, fully rechargeable unit that allows for complete OFF GRID operation. The exceptional storage system allows for up to 3 days continuous illumination without a single recharge!

 

Compared to traditional on grid LED street light system, it needs labors to dig and install the necessary wiring, re-asphalt and install the light poles and this requires considerable investment and time for execution. It is too complex, and for solar led street light system, it is easy to install it pole or anywhere which needs to be lighted. More easy and flexible.

Solar Lighting For Safety
Click Volume:0

When most people think of solar lighting for safety, they think of solar flood lights or solar security lights with motion detectors.  While its common knowledge that good outside lighting is a crime deterrent, criminal activity is not the only safety hazard that exists in dark places.  Unlit stairs and edges can be even more of a safety hazard than a potential burglar.

Solar lighting can be the perfect solution to illuminate steps or ramp edges that are not visible in the dark, or pathways that cover uneven terrain.  While the cost to install electrical wiring along a winding pathway could be prohibitive, solar path lighting could be easily and inexpensively installed.  The same holds true for installing solar step lights, or solar lighting along a ramp or dock.

A multitude of solar lights are available that are mounted on stakes for anchoring into the ground, or on clamps that can be attached to the side of a step or ramp.  For best illumination, choose a product with a super bright LED light.  You won’t have to worry about bulbs burning out, since LEDs are built to last for about 20 years.  And the illumination level is comparable to halogen bulbs.

Most outdoor solar path lights have built in solar panels and photo cells.  This allows them to recharge on a continuous basis, and they will automatically turn on at dusk.  If you buy lights that use rechargeable Ni-Cad batteries, the lights will work even if they don’t receive enough direct sunlight for the solar panels to fully recharge during a stretch of cloudy days.

Many of the decorative pathway lights come in a variety of colors (red, blue, green and amber are the most typical).  But for safety purposes and the best lighting, white light is the brightest.  However, light that is too far at the cool (blue) end of the spectrum can be glaring, and some people have a sensitivity to it.  So check with the manufacturer to ensure that the “white” light you buy is at the warm (yellow) end. of the spectrum for maximum safety and comfort.

Solar Lights in Developing Countries
Click Volume:0

Billions of people around the world are still living without electricity. Till recently, the only solution for those people to get lighting was to use kerosene lamps or candles with all the risks involved. Thanks to solar lights technology things are improving.

 

Efficient and affordable LED solar lights are now available for the developing world.

 

Fortunately, several companies are working on portable solar solutions to help those people improve their lives and prospects with efficient and clean lighting. One of them is Nokero, short for “no kerosene” and which offers a range of solar light bulbs and solar phone battery chargers.

There is a real need for clean and safe solar lighting in developing countries

 

Although solar lighting seems like an obvious solution, people without electricity are not able to make the transition from kerosene due to high up-front costs. Peole living on less than a dollar a day simply cannot afford a light for $20-$50. One Million Lights help families shift wasteful kerosene cost to productive investments in education, nutrition, and healthcare.


One Million Lights distribute solar lanterns in Bangladesh, Cambodia, Ghana, Haiti and many other countries around the globe.

 

Lighting Africa, a World Bank project has certified a list of solar lights that meet minimum standards for reliability, brightness and run time.

The Technology Behind Commercial Solar Lights
Click Volume:0

Thanks to the advent of bright LEDs, lithium batteries, charge controllers and highly efficient solar cells, modern commercial solar lights are extremely reliable and compare to their electric counterparts. 

Solar lights weren't always capable of such remarkable performance. Since solar powered lighting need to give off light when the sun is down, they are always limited by the amount of energy they can store. The more efficient the light source they use, the smaller the batteries and solar panels can be. The invention of extremely bright, efficient LEDs made solar lamps widely usable... and very popular.

Why are LEDs Key to Commercial Solar Lights

LEDs have been around for decades, often as the little indicator lamps on home electronics. Manufacturers love them for this purpose because they're extremely efficient: putting out quite a bit of light while drawing very little power. This makes it possible for electronic gadgets to last longer on one set of batteries.
Only recently, however, did it become possible to produce white light from these LEDs, or make them bright enough for use as lighting instruments. When the power flows through an LED, particles of light are released from a junction between two specialized materials. The wavelength, or color, of light released from this junction depends on the materials used, and it is always just a single color.

A few years ago, scientists realized it wasn't just possible to make LEDs that were as bright as or brighter than regular bulbs. It turns out that by applying a phosphor coating to an LED chip would turn one color into white light. 

Like the original LEDs, these white models offer extremely high efficiency on a lumens-per-watt basis, but they also offer brightness almost comparable to regular lighting fixtures.

Improving the efficiency of LEDs is one more key factor that makes them much brighter than similar lamps of other types.

LEDs generally only emit light in one direction. Whereas fluorescent and incandescent bulbs require a light-gobbling reflector in order to focus the light, LEDs are directional by default. Reflectors, if needed, can be much smaller, and integrated into the solid-plastic packages that make LEDs so weather resistant.

The Efficient of Solar Street Lights
Click Volume:0

Solar street lights can be deployed in no time. They will provide years of operation and require minimum maintenance.  Thanks to the use of LEDs, efficient solar panels and reliable batteries solar street lights can back up for several day of bad weather.

 

Solar street lights give you a very clear idea about what can be achieved with solar energy. They consist of a solar panel, rechargeable battery, solar charge controller and LED lamp. Solar powered street lights can be equipped with photocells for dusk to dawn operation or timers to control the lighting duration.

The solar-powered LED Street light is competitive with grid-based street lights and delivers 98% power-conversion efficiency from the photovoltaic cells to battery.

CRESOLAR has developed an innovative, sustainable and highly efficient all in one solar powered street lighting solution.

Solar street lighting can be an economically viable option in many applications. Not only in the areas where the cost of providing electricity is too expensive, but also in situations where reducing running costs is a priority.

Solar street lights are a judicious choice for parking lots, parks, highways, roads airports, area lighting and many other public, private and military sites. Some solar street lamps can run at low power when no activity is detected underneath. They will switch back to full illumination as soon as movement is detected.

Smart Use of solar lighting to highlight specific items
Click Volume:0

The first thing to keep in mind when placing solar street lights and other decorative solar lamps in multiple areas of your garden is that you should make sure enough illumination is present to highlight items of choice in your garden. This could be anything ranging from a tree, a statue or pond.

Another enhancement you can make with solar lighting is to accentuate shadows. This is easily done by positioning the lights at ground level and in relevant areas which will effectively highlight the objects of your desire.

Solar lights can also be used to project light down on the garden; this method is very useful in a situation where light must shine directly up a tree must and enable a very nice dappled effect. It can also enhance the angles present in your garden as well as giving a softer appearance.

Another great effect would be placing a solar powered light directly underneath the object to be illuminated, this gives a great highlight for the item you have chosen and will make them very noticeable at night.

These small tips highlight how solar lighting can easily be installed anywhere and are not constrained as to their location. Indeed the only issue with placement is that the solar panel should be able to get enough sunlight for a full charge of the batteries.

Solar lights are used in homes all around the world; this is due to the great availability of such great technology. This however means that there is a large range of products that differ in quality and price. This is a very strong contrast to the first solar light models which had very low illumination, of course the technology keeps changing and we are finding that better and more efficient solar powered lights are coming into the market every year.

Solar Street Light Played an important role in New Countryside Construction
Click Volume:0

In 2015 - 2016, CRESOLAR increased the pace of the solar street light construction in new rural countryside. With the advance of new rural construction, rural road lighting project has become a big part of the plan in official’s new rural construction plan. However, in the past, because of the complex phenomenon of rural areas, rural lighting project existed a lot of difficulties, such as:

1, Investment issues for road lighting construction project;

2, The installation process is complex, it has to occupy agricultural land, digging, layout the cable etc.

3, It has to pay the electricity charge, because the cost can’t be solved, so it resulted in the issue that after the installation of the lam, most the lamp almost are not bright, it didn’t play a real role of lighting efficiency to peoples.

4, The maintenance work is cost too, as replacement parts, the original device and so on.

5, Energy consumption is too big, no energy saving but cause environment pollution problem.

But by the using of the solar road light, all the problems have been solved directly. Solar lighting system has properly solved all the existence problems in rural lighting construction; it becomes a new "star" role in rural country construction.

And the biggest advantages of solar lamps are as below:

 

1, Energy saving, environmental protection and it is the green lighting which our country vigorously promote.

2, Investment funds is easier to be solved, because it is energy-saving environmental protection products, in all places esp. for new rural countryside construction project, our state of government will give special founds support.

3, Less investment, comprehensive economic benefits is basically the same as conventional street.

4, The installation of solar street light is quite simple, no need digging ditch, and the construction duration is also short.

5, No electricity charges, 100% by sun power.

6, Almost maintenance free, because the LED light source life of more than 10 years.

7, Smart all in one design, more attractive than the traditional street light, forming a beautiful landscape in countryside area.

8, Solar Street light brings the concept of energy conservation and environmental protection to people in rural areas, and guide the rural people awareness of energy conservation.

In the past few years, CRESOLAR has built dozens of solar street light in new rural construction in Hunan, Hubei, Inner Mongolia and other large, it has bought bright and convenient to local villagers life, making their night warm and beautiful in everyday.

To 2017, CRESOLAR believe that they will bright more bright and convenient to more rural villages. Let us work together!

Solar street lamps VS Electricity Street lights
Click Volume:0

Nowadays Solar LED street lamps are gradually taking replace of the electricity street lights by its own advantages. By the mentioned solar lamps, most of us are no strangers, in villages many rural roads have installed solar street lamps, it was energy saving, environmental protection and easy installation. Therefore, what are the advantages of solar street lamps compared to city powered lights? Today, CRESOLAR will talk about their difference from the three aspects. First of all from the security which is the most important part, then compared the cost between them, and finally through the installation to contrast:

 

1, Safety contrast:

Due to the reform of construction quality and landscape engineering, the city electric lighting road lamp brings many hidden dangers, such as aging of material, abnormal power supply, conflict of water, electric and pipeline. Because the solar street lamp is 100% power by sunshine, it doesn’t have any cable, and adopts 12 - 24V low voltage, the voltage is stable, the operation is reliable, and there is no hidden danger of safety.  It is the ideal product of the ecological district and the highway department.

 

2, Cost comparison:

City circuit lamp costs electricity, except it has an expensive electricity bill, but also has complex lines, during the using, it needs labors to do uninterrupted line maintenance in a long-term. Especially, in same voltage instability situation, the sodium lamp is easy to break inevitably. Also with the extension of number of years, the aging of the line and the cost of maintenance are increasing year by year. However, Solar Street light is a one time investment but long-term benefit. Because no cable needed, so there is no maintenance cost, do not have any electricity bill. It can recover the costs by 6 - 7 years, and can save about RMB1, 000,000 of the electricity and maintenance costs in the next 3 - 4 years.

 

3, Installation comparison

There are complicated operating procedures in the construction of city circuit lights. First of all, the cable should be set up, trenching, cloth pipes, pipes, threading, backfill and other large civil construction, consuming a lot of manpower, material and financial resources. Finally, debugging, once there is a problem, it will cause great consumption. When the solar street lamp is installed, the complicated circuit is not needed, only a cement base is made for the pole, and fix the solar lamp on the pole is OK, too simple and easy. Saving a lot labor cost!

24 Solar Terms: Grain Buds in May
Click Volume:0

The traditional Chinese lunar calendar divides the year into 24 solar terms. Grain Buds, (Chinese: 小满), the 8th solar term of a year, begins on May 21 this year, and ends on June 4. It means that the seeds from the grain are becoming full but are not ripe.

In China, the 24 solar terms were created thousands of years ago to guide agricultural production. But the solar term culture is still useful today to guide people's lives through special foods, cultural ceremonies, gardening and even healthy living tips that correspond with each solar term. Let's see what we can do during the "Grain Buds" period.

What’s inside a solar-powered LED light
Click Volume:0

In developing countries, where kerosene is an expensive and potentially hazardous energy source, solar-charged battery-powered LED lighting can be a money-saving, safer alternative. Nokero (“kero” being the shortened name for kerosene) was one of the first companies to venture into the emerging market. Here’s a look inside to see what design decisions were made (see Figs. 1 and 2).

Fig. 1. The light side of Nokero’s Shavano N220 solar light.
Fig. 1.

Nokero’s Shavano N220 outputs 29 lm on its high setting, 14 lm on low, and when fully charged, it will run for 3.5 hours on high, 6 hours on low. You choose between high, low, and off with a 3-way switch. The light also has a photosensor that automatically turns it off when there’s enough light to charge the battery and presumably the LED doesn’t need to be on.

Fig. 2. The solar side of Nokero’s Shavano N220 solar light
Fig. 2.

The light is housed in a package reminiscent of an oversized incandescent light bulb. You can hang it outside in the sun on a line or a hook while charging from a clip that’s attached to the base of the light, which looks like the screw end of a light bulb. The light’s solar cell is the SunPower Maxeon.

The N220 has a single 1/3W LED that might be a Seoul Semiconductor Top View 5630. (For a slightly more detailed look at the LED and battery placement, you can go to the Designing with LEDswebsite.) The prominent ICs on the board are a 6-pin IC that looks like a switching boost regulator, and an 8-pin chip, most likely a microcontroller. Neither of the ICs have any markings (see Fig. 3).

Fig. 3. The PCB of Nokero’s Shavano N220 solar light.
Fig. 3.

The two 1.2V 1200 mAhr NiMH batteries are in series and provide 2.4V to the 6-pin IC – the one that I’m assuming is a constant-current boost regulator, which operates at about 1.1MHz and boosts the voltage up to 3.2V. When switched to high, the LED is powered at 3.2V and 110 mA. The specs for the N220 say it will put out 29 lm at this power, which matches with the specs in general for a 1/3W LED such as the 5630.

When switched to low, the voltage across the LED changes to a 50-50 duty cycle at about 640Hz: During the “on” portion of the cycle, the voltage is 3.2V and the LED turns on, while during the “off” portion of the cycle, the voltage falls to 2.6V, which is below the LED's Vf and the LED turns off. The overall current drops to an average of about 50mA or half-power. It looks like the 640Hz signal is generated by the 8-pin IC, which I’m assuming is a microcontroller.

This is a neat way of dimming the LED, much better than simply dropping the analog current through the LED which is a less efficient use of power and can result in a change in the LED's color temperature.

The microcontroller itself didn’t match up with any of the 8-pin versions of the usual suspect microcontrollers. It’s likely that it is one of the special-purpose uCs made in China just for controlling LEDs. The huge size of the large garden solar light industry enables a lot of ASICs for LED control that couldn’t otherwise justify a custom IC.

Philips acquires French Li-Fi company
Click Volume:0

Holland’s Philips Lighting has quietly acquired a small French company specializing in visible light communications (VLC) in a move believed to be aimed at boosting Philips’ capabilities in Li-Fi, the light-based technology expected to provide Wi-Fi-like two-way Internet communications.

Interested in articles & announcements on Li-Fi & smart lighting technologies?

The company, Luciom, has relocated from Colombelles near Caen in northern France, to Philips Lighting headquarters in Eindhoven.

“Philips Lighting acquired Luciom at the end of 2016,” a Philips spokesperson confirmed for LEDs Magazine, noting that all eight of Luciom’s employees now work for Philips.

The spokesperson would not say whether the eight will continue to operate under the Luciom banner.

“Together the companies study a number of technologies that could enable existing and new lighting technologies,” the Philips spokesperson told LEDs Magazine. He declined to say what the Luciom team will now focus on. Luciom chief executive Michel Germe did not reply to LEDs for a comment by press time.

Before relocating to Eindhoven, Luciom worked out of facilities in a French office plaza called Esplanade Anton Philips (pictured), named for an early Philips boss from nearly a century ago and which houses the former Philips semiconductor group now called NXP. (Source: entrevoirart.blogspot.)

Luciom is developing several technologies related to VLC, including Li-Fi. Philips appears to be particularly interested in Luciom’s potential to improve Li-Fi in several ways, including speed, coding/decoding, and reliability.

Li-Fi in general has remained stuck in a nascent stage, limited to pilot implementations and demos from vendors such as Scotland’s pureLiFi and others. Philips is expected to invest in the Luciom technology in a push toward commercializing it. Once Li-Fi takes hold, the idea is that it can become another means of wireless Internet transmission. It would complement Wi-Fi in large part by opening much more frequency to Internet use; Wi-Fi with its radio frequencies is more limited than the considerably wider spectrum of LED lightwaves on which Li-Fi data rides.

Luciom is best known for a “tagging” scheme, which individual LED lights use to uniquely identify themselves in one-way indoor-positioning systems. Compared to two-way Li-Fi, indoor-positioning is a more basic form of VLC that sends small amounts for information from a light to a phone or other gadget. A number of retailers are experimenting with one-way VLC to try to engage shoppers in stores with information and direct them to promotions. Philips has had a trial with a Carrefour store in France and with the Dubai-based retail chain aswaaq. In the US, Target is trialing the technology, although it has never revealed its supplier, as our sister publication Lux Review has reported.

Philips is believed to have acquired Luciom for less than €10 million. LEDs understands that at one point Philips might have raised patent infringement queries related to Luciom, which could have factored into the price of the purchase.

“The terms of the acquisition were not disclosed,” the Philips spokesperson said via email, in response to questions about any patent implications.

For Germe and Luciom, the acquisition is a sort of corporate back-to-the-future, as Luciom evolved from NXP Semiconductors, the Eindhoven-based semiconductor company which was until 2006 Philips’ semiconductor division.

Germe himself was an LED lighting architect at NXP, and worked as a radio frequency specialist at Philips Semiconductors in Caen from 2000 to 2006, according to his LinkedIn profile. Luciom’s offices near Caen were in a plaza called Esplanade Anton Philips, presumably named for the son and brother of Frederik and Gerard who co-founded Philips Electronics in 1891. Anton and Gerard are credited as co-founders of the 1912 incarnation Royal Philips Electronics N.V., and Anton was CEO from 1922 to 1939.
