A Rutland village has cut its energy bills by almost 80% by switching to more efficient lighting.

Market Overton's street lighting bill fell from about £80 in October 2010 to about £15 in November.

The savings are as a result of replacing the village's old sodium street lights with modern light emitting diode (LED) lamps.

The parish council also turns off some of the village lights between midnight and 0500 GMT to further reduce bills.

Parish councillor Andrew Stewart said: "We still have the lights on at important junctions and places you would need to see.

"Turning 80% of them off at midnight has really helped to save money and to cut our carbon footprint."

The parish council updated its 39 street lamps at a cost of £20,215 with about a quarter of the cost being met by a Rural Community Council grant.

Councillors said the village would no longer receive a quarterly £600 bill for maintenance and the lamps were guaranteed for 12 years and expected to last for 20 years.

LED Bulbs - The Light Of The Future

As we become more conscious about the effect that the use of electricity is having on our planet. So the more aware we are becoming of looking for ways to reduce our use. As a result of this the sale of LED bulbs has increased substantially in the last few years.

Today it isn't just companies who are choosing to install such lighting but many homeowners as well.

So what are the reasons for so many us choosing to spend money on installing LED light bulbs rather than sticking with the incandescent and fluorescent ones?

In this article we look more closely at the features of LED bulbs and which will explain to you why such lights are proving so popular today.

Feature 1 - Luminous Flux

At the present time LED lights have the ability to produce a luminous flux of between 1 and 120 lumens. In turn they need only to use power of between 50-100mW (MiliWatts) and 5W (Watts) to create the light they produce.

Feature 2 - Color and Color Temperature

Most of the LED bulbs you see today emit a very neutral white light which many of us see as being cold. However research is being carried out and in the future the lights will be able to produce a much warmer light that looks very similar to that which a traditional tungsten or halogen bulb produces.

Feature 3 - Life Span

As these lights use less energy to create the light they don't get as hot as conventional light bulbs do and this in turn means that they last considerably longer. If you are willing to purchase good quality LED bulbs you will find that they will provide light for between 30 and 50,000 hours. Whereas you will often expect a conventional light bulb needing to be replaced between 5 and 10,000 hours.

Feature 4 - Light Distribution

How intense the light distributed by such bulbs is will depend on the housing used and what sort of carrier or reflector has been used to place the semiconductor on. Certainly the better quality these components then the more intense the light distributed will be. On average the amount of light emitted can vary dramatically and the angle at which it is emitted varies also. In some bulbs the angle is just 15 degrees whilst in others it can be as much as 160 degrees.

Feature 5 - Energy Efficiency

These are considered to be among the most efficient form of lighting you can get today. At present most of these bulbs are able to emit around 30 lm/w of white light. However there are a few now that have the capability of emitting 50 lm/w and hopefully at some point in the future some will be able to emit 100 lm/w. So it won't be very long before these types of bulbs have the ability to emit the quality of light that traditional light sources currently provide.

As a result of all these features it will not be very long before you seen LED bulbs replacing the much more inefficient forms of lighting we use currently.

Meerut to have LED street lights by

April

All the 37,000 street light points in Meerut municipal area are going to be replaced with Light Emitting Diodes (LEDs). Meerut Municipal Corporation officials said the LEDs would reduce the electricity consumed by street lights by almost 60 per cent and so will save on monthly electricity bill.

LED lights are going to be installed in Meerut on a pilot basis in Uttar Pradesh and for that the Meerut Municipal Corporation (MMC) has tied up with Energy Efficiency Services Limited (EESL) to conduct a survey to find out the conditions, power consumption and output of street light points in the city. EESL is a joint venture of PSUs of the Ministry of Power, the Government of India.

Sources said the MMC has received a letter this week from EESL stating that its officials would soon visit Meerut to start the survey. Officials said that after the survey, bids would be invited to install LED lights on Public-Private Partnership model and installation of LED lights would begin by April.

alking to The Sunday Express, Meerut Municipal Commissioner D K Singh said, “All the street lights in Meerut are going to be replaced with LED lights. It will save energy and prove cost-effective.” The assistant engineer, Meerut Municipal Corporation, SS Chauhan, said, “Meerut corporation pays around Rs 65 lakh every month as electricity bill of 37,000 street lights. Once the LED lights are installed, power consumption would reduce by almost 60 per cent.

An LED street light is an integrated LED light fixture that is more efficient compared to bulbs and tube lights of the same luminance currently in use.

Uniform illumination from Osrams

LEDs helps light up Guangzhou for

Asian Games

LED lighting brings uniform illumination to the Zhujiang New City Central Business District (CBD) in the city of Guangzhou in time for the Asian Games in China. On centre stage are OSRAM Opto Semiconductors’ Golden DRAGON Plus LEDs, installed in the street & parking lamps of the Haixinsha People square in Lin Jiang Road where the Asian Games will be unveiled. These LED lamps will provide an evenly illuminated environment for pedestrians and for drivers in the parking lot. 

Haixinsha is the largest public plaza in Guangzhou, measuring 170,000 square metres. OSRAM’s Golden Dragon Plus LEDs were chosen for their good viewing angle and high lighting performance. With a viewing angle of 170∘and luminous flux of 116 lm at 6000K at an operating current of 350 mA and up to 273 lm at 1000 mA, these LEDs enable uniform and high efficiency lighting in such an expansive area. 

These LED lamps were installed by Guangdong Zhonglong Communications Technology. Last year, Zhonglong has already installed LED street lamps using OSRAM’s Golden DRAGON Oval Plus LEDs in the Zhujiang New City CBD. Following the success of the previous project, the company started several others, including the one in Haixinsha Plaza. 

“LED is once again proven to be the new generation of light source,” said Mr Chen Ben, General Manager of Guangdong Zhonglong Communications Technology Ltd.. “As the Opening and the Closing Ceremonies will take place in Haixinsha Square area and thousands of visitors will witness the benefits of LEDs in general illumination, we hope this will drive the adoption of LEDs in other applications.” 

The Golden DRAGON Plus series are specifically designed for general illumination applications. The long lifetime in the range of 50,000 hours make them ideal for outdoor lighting, as they require very low maintenance and thus cause minimal disruption to traffic. 

“OSRAM is extremely proud to help light up the roads leading to this major event,” said Kai-Chong Cheng, Marketing Director of OSRAM Opto Semiconductors Asia Ltd.. “We understand the importance of uniform lighting in street lamps and therefore have developed products which can meet this requirement. Our ThinGaN chip technology not only enables products with long lifetime but also small form factor and low energy consumption, making LED becomes a viable and cost effective light source for outdoor applications.” 

Since the launch of “10 Cities, 10,000 LED Lamps” in China, local governments are using LEDs in new roads. Among them, the Guangdong provincial government has also started its “10,000 LED lamps in 1,000km” project. It proves that the country is leading the momentum of LED street lighting applications.
