WAYS TO SAVE IN PUBLIC LIGHTING
Often times the fact that lighting represents 10% of the total energy consumed in the world goes unnoticed. Changing this situation is easy by adopting a series of measures that can easily be implemented. Of these measures it is worth mentioning that by simple replacing obsolete equipment, the savings that can be achieved in the case of public lighting may reach over 50%.
From Cadielsa we propose different solutions that we make available for you to achieve a more efficient lighting.
The purpose of the proposed solution is to achieve several objectives: on the one hand to reduce the electrical consumption and to achieve an energy savings that also results in a cost savings. On the other hand, to use more efficient technology to improve the performance of the installation and decrease pollution as much as possible.
The first thing we must do when we wish to improve public lighting at a location is to analyse the current situation; checking if the luminaires as well as the lamps are the most appropriate.
Analysing the current situation in Spain we find that many towns use mercury vapour as the main technology for public lighting. Mercury vapour is not a very efficient technology and this is why the manufacturing of this technology was discontinued by directive 2005/32/EC. The reason was because its lm/W performance is lower than what we would achieve using other more modern technologies.

ADVANTAGES OF USING ELECTRONIC EQUIPMENT
1- Electronic equipment consumes less energy than electromagnetic equipment and therefore achieve a higher energy savings.
2- Since this equipment ensures a constant power reaches the lamp, it causes the lamp to always supply the same light flow, which will be optimum for the lamp because the light that is emitted will be free of any bothersome blinking.
3- It ensures a longer service life for the lamp.
4- If the service life of the lamp runs out, the lamp is defective or no lamp is installed, the equipment will automatically turn it off.
ADVANTAGES OF USING FLOW REDUCERS
1- Energy savings; reduced energy consumption. Flow regulators stabilise the voltage and softly reduce the luminous flow. Also the cost of installing and maintaining these installations is low, they achieve a luminous uniformity and an important energy savings.
2- Economic savings: reduction of the electrical consumption, maintenance and replacement bill.
3- The equipment can be easily installed at the heads of each line and not at each point of light, they can be adapted to all types of installations, new or existing and to the types of lamps that are available on the market.
4- Quick amortisation; between 6 and 24 months.
5- Lower CO2 emissions, environmental protection while maintaining the natural daylight conditions as much as possible.
ADVANTAGES OF LED TECHNOLOGY
1- LED lamps provide a great energy savings and are adjustable.
2- They have a long service life and therefore the maintenance costs are lower.
3- The quality and intensity of the white light that is generated by LED sources has improved in recent years, which has made them a magnificent alternative to using conventional light sources.
4- LEDs offer an infinite palette of colours or white light tones.
5- Since this is digital technology, the LEDs may be programmed, which allows to efficiently manage the lighting.
