Outdoor Lighting

  • Introduction

 According to the definition of International Commission of Illumination, lighting means “Application of light in order to ensure that the environment and objects are seen as necessary.”

Unlike indoor lighting, the important point in outdoor lighting is to determine the lightness level and calculate environmental conditions in line with the data established and to ensure energy efficiency and saving.

In the areas where we render service, our primary objective is provision of required lighting as well as efficient use of energy and ensuring saving. It is possible to provide high quality lighting with little energy consumption.

*If high pressure sodium vapor lamps are used in road lighting instead of high pressure mercury vapor lamps, energy is saved by approximately 60% on the same lightness level.

If low pressure sodium vapor lamps are preferred instead of high pressure mercury vapor lamps in garden and environmental lighting, energy saving of approximately 70% can be achieved on the same lightness level. Outer door lamps can be replaced by halogen lamps.

Light outputs of all lamps decrease in time. The lamps with decreased light output, in other words, with decreased efficiency should be replaced.


LEDs, which are used at every stage of our lives, are preferred frequently in lighting systems thanks to their high performance. They have started to replace classical bulbs as they last long and are applied easily. They last 100.000 hours on average. They consume energy by 1/10 compared to conventional florescent lamps. They have a broad area of use including architectural areas thanks to their different color choices.

Properties of LEDs

  • They operate on direct current.
  • They have low energy consumption.
  • They are easy to use.
  • They are long-lasting.
  • They have short response time.
  • They have high light efficiency.
  • They have long heating time and the heat amount produced is low.
  • They can be used in any color and intensity desired.
  • They are resistant to shakes and impacts.
  • They are environmental-friendly as they do not include such gases as mercury or halogen.


  1. Red LED operates on 2,20 Volt
  2. Green LED operates on 3,30 Volt
  3. Blue and white LED operate on 3,40 Volt voltage.


Solar lighting system operates independently from electric networks. It has low cost. It has no cost except for lighting fittings and assembly. It can easily be used in anywhere without energy constraint.

It has been preferred frequently in recent years as it is clean and environment-friendly energy.

We usually use this system, which has a wide area of use, in the below-mentioned cases:

Outdoor lighting,

  • Places away from settlements,
  • Telecommunication stations,
  • Protection of metal structures against corrosion,
  • Meteorology and observation stations,
  • First aid, alarm and security systems, earthquake and meteorology stations,
  • Pharmaceutics and vaccine cooling,
  • The opportunity of application and operation in any region desired independently from electric network,
  • Environment-friendly and long-lasting system,
  • It is not affected by energy restriction and it offers the opportunity of use everywhere.


Security lighting is the type of lighting materialized for the purpose of being protected from dangers which can arise and ensuring safety. People generally define light places as secure and associate them with a secure environment.

For this reason, places such as streets, squares, tunnels and crossroads where people are often available, should be lightened correctly in terms of security.
