The solar street lights are designed to function fully throughout the night without any failure. Many integrated solar street light can stay on for more than one night even if the sun is not available for a couple of days.The solar lights that are installed in specific windy areas have been equipped with flat panels to better survive the strong winds.
The updated models of solar street lights use wireless technology and fizzy control theory for better battery management. These street lights mainly use the technology of a network operation where one light can perform perfectly while the other would stay off.Parts of a Solar Street Light:The main part of a solar street light is the solar panel that converts solar energy to electricity with the help of photo voltaic cells.
Two types of solar panels are available:Â· Mono crystalline: The conversion rate is much faster and they are quite expensive.Â· Poly-crystalline: The conversion rate is slower and produces less power.LED is the next component and is the lighting source of most of the street lights.
It provides much more lumen while consuming less power. The energy consumed by LED is 50% lesser then the standard HPS which is used in traditional street lights and lamp poles.Rechargeable Battery: Most of the Solar Street Light in China has a strong battery than can store electric charge converted from solar charge consumed during the day light and provide power at night.
Advantages of Solar Street Light:Â· They are self-governing that is they don't need a utility grid so the operation cost is quite less.Â· They require less maintenance so less maintenance cost.Â· The risks of shocks are limited as there are no external wires or connections.
Â· It is the best form of Eco-friendly technology.Â· It allows the saving of energy and cost too. Follow us on Our Social Profiles Links: com/dihongzm/.
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!
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!
