Final ReportSummary - ECOSTREETLIGHT (Development of 25% more energy efficient street lights with integrated reflector, elimination of protection glass, optimized arc tube and improved luminaire desig
The ECOSTREETLIGHT project is a Seventh Framework Programme (FP7) project for research for small and medium-sized enterprises (SMEs). It has an official start date of 15 September 2008 and lasted for 30 months. The beneficiaries in the project are as follows: Gavita AS (SME and coordinator), Telux-Spexialglas GmbH (SME), GP Diecasting Limited (SME), Tridonic Atco GmbH &KG (OHT), Teknologisk Institutt as (research and technology development (RTD)), Labor S.R.L (RTD) and Universitat de Girona (RTD).
The ECOSTREETLIGHT project aims to develop a 25 % more energy efficient street light with integrated reflector, elimination of protection glass, optimized arc tube and improved luminaire design.
The increased efficiency is to be accomplished by a new and innovative type of light bulb with an integrated reflector. The advantage with an integrated reflector as opposed to a conventional light bulb is that there is no need for a protection glass. The elimination of the protection glass will alone increase the efficiency of the light bulb with 10 % to 20 %. Typical efficiency of reflectors is 80 % - 90 % today. The aim of the project is to develop a new method for reflector coating which will give our reflector an efficiency of 95 % - 98 %. An arc tube specially adapted to street lights will have an increased efficiency compared to today's street light arc tubes of 5 % to 10 %.
The project was completed on 14 March 2011. During the project, scientific knowledge was established through literature studies, contact with target market representatives, theoretical simulations and most importantly, a lot of design and engineering work. The work can be divided in three main parts:
- reflector design and development; which include all work related to the theoretical design of the reflector shape and the engineering work in converting the reflector shape into a glass bulb;
- coating of the glass bulb; which include both theoretical studies and a lot of experiments;
- mechanical design and construction of each component in the complete luminaire, which has resulted in a new luminaire that is smaller, simpler, cheaper to produce and easier to maintain than current street lights.
Project context and objectives:
The ECOSTREETLIGHT project aims to develop a 25 % more energy efficient street light with integrated reflector, elimination of protection glass, optimized arc tube and improved luminaire design.
The increased efficiency is to be accomplished by a new and innovative type of light bulb with an integrated reflector. The advantage with an integrated reflector as opposed to a conventional light bulb is that there is no need for a protection glass.
- The elimination of the protection glass will alone increase the efficiency of the light bulb with 10 % to 20 %.
- Typical efficiency of reflectors is 80 % - 90 % today. In our proposed project we will develop a new method for reflector coating which will give our reflector an efficiency of 95 % - 98 %.
- An arc tube specially adapted to street lights will have an increased efficiency compared to today's street light arc tubes of 5 % to 10 %.
- The integration of an electronic dimmable ballast.
- Improved design of the lighting fixture.
Project results:
The project has achieved to:
- design, develop and produce a glass bulb with an internal reflector;
- design, develop and produce a new luminaire that is smaller, simpler and cheaper to produce and maintain than current solutions;
- investigate different coating materials and conclude on the best coating alternative;
- established a method for internal coating of the glass bulb.
When evaluating the increase in efficiency for the street light, we have chosen to look at pole distance as the key factor since that is the cost factor that is seen when street lights are being installed or retrofitted. The calculated results show an efficiency improvement ranging from 5 % to 29.7 % depending on which road class:
- road width 10.5 m, 3 lanes, pole height 12 m (S9 road class)-> 5.15 % improvement;
- road width 7 m, 2 lanes, pole height 10 m (S9,S8 and S7 road classes)-> 17.0 %improvement;
- road width 6.5 m, 2 lanes, pole height 10 m (S6 road class)-> 17.0 %improvement;
- road width 3.75 m, 1 lane, pole height 10m (S5 road class) -> 6.5 % improvement;
- road width 3.2 5m, 1 lane, pole height 10m (S1 road class)-> 29.7 % improvement.
It is decided not to publish any details regarding the street light concept as it is going to be patented and any publishing of results prior to patenting will prevent a patent for the concept.
Potential impact:
The main impact is that less energy can be used by installing the street lights. Calculations show that the ECOSTREETLIGHT has an efficiency improvement between 5 % to 29.7% depending on road class. In addition, when the reflector is sealed in vacuum inside the bulb, it will not deteriorate with time as conventional street light reflectors, which is exposed to the surrounding will. The owner of the street lights will be able to save energy and thus cost by installing the ECOSTREETLIGHT luminaire. Less energy used for lightning is a huge benefit for the environment as the production of electricity needed to power street lighting systems adds to carbon dioxide emissions.
Streetlights are important assets in order to create safe roads and public areas. As much as 40 % of a city's electricity consumption is used on streetlights. As the cost of the electricity continues to rise, it will be more and more focus on reducing the consumption. Worldwide, the price of electricity has increased drastically over the last five years. Analysts are forecasting a continuous increase over the next 10 years. Thus, the potential market for the ECOSTREETLIGHT lamp seems very promising.
Dissemination activities
No details about the ECOSTREETLIGHT concept have been presented to the public so far since it is decided to keep it confidential, but both the coordinator and the large enterprise Tridonic have been participating to lightning exhibitions in Scandinavia, Europe and China. They have both a deep understanding of the general lightning sector and they have an extensive contact network within the target sector for the ECOSTREETLIGHT sector. The large enterprise, Tridonic has expressed their commitment to contribute with detecting and opening possible market channels for street light post-project. Tridonic has their main contact network in Europe. In addition, the coordinator has attended several exhibitions in China and he is getting more and more contacts in the world wide market. The team of Tridonic and the coordinator Gavita is believed to be a strong team in finding the most efficient way of entering the market.
