A total of 10,000 bulbs, with a duration of six months, be exchanged for new, lasting up to 10 years
A total of 165 intersections with traffic lights will light LED lamps, which consume 80% less energy and last up to 10 years, compared with six months of traditional light bulbs.
To start this work, the Department of Traffic, directed by Nuria Fuentes, to provide greater safety for pedestrians and drivers, has devised a series of crosses in which it becomes more necessary to install new lights, offer better visibility.
Installation will begin for the urban and extended to 11 districts whose property crosses on municipal roads require this change.
This initiative is also part of the measures contained in the Local Strategy to combat climate change has prompted the Mayor of Murcia, Miguel Angel House, through the Local Energy Agency (ALEM).
Nearly 10,000 older bulbs will be replaced.
The old traffic lights, consisting of a bulb behind a colored glass (green, amber or red), a new model that includes a multitude of tiny colored lights, which together, and as a pixel, create an effect similar to that previously had, with the advantage that they offer greater visibility from almost any angle, while traditional lights require a frontal view.
The number of LEDs currently available is 2,000, installed since 2005.
During the next two months will be installed exactly 9981, which is a performance of 165 crosses.
Thus, once this phase, technology will have led 58.7% of the traffic lights of the city.
The change will start in the next few days in central Murcia, Calle Correos, Lieutenant Flomesta, Juan de la Cierva, García Alix, San Anton, and gradually extended to other points farther from the center.
The City Council approved the specifications for this service and has been provisionally awarded the work to Traffic Murcia, SA The Consistory will invest 200,000 euros in this improvement.
The technology they use these signals is called LED (Light Emitting Diodes or LEDs), which consists of an electronic device that emits light of one color when electricity passes through it.
Thus, the sufficient grouped in a matrix leds, light emitting amount needed to replace a halogen in applications such as traffic signals, signs or decorative lighting.
The application of LED technology in traffic signal provides greater security, since the high brightness light emitted allows perfect perception of signals even in the most adverse conditions.
Besides the disappearance of the reflector that have conventional traffic lights, avoid the viewer dazzled by the sun when the rays of it entering the reflector.
These lamps, which can save 80% power, provide more safety to traffic because they are more durable (lasting 10 years compared to 6 months of a conventional lamp) and are more reliable because when you merge gradually fade away.
Likewise, this technology allows that where before there was only one focus now has over one hundred, which ensures that no traffic lights to stop working if one of them melts.
Remember that traffic lights at intersections are being made in new areas and these bulbs are installed.
LED technology is already built in streets such as Gran Via, Lieutenant Flomesta and Juan de la Cierva among others.
As a curiosity, we may add that the number of LEDs per bulb is:
Semaphore 300 mm.
red, amber and green LEDs 204.
Semaphore 200 mm.
red, amber and green LEDs 120.
Pedestrian traffic light 81 red LEDs.
Pedestrian traffic light 66 green LEDs.
Semaphore 100 mm.
red, amber and green LEDs 30.
