Lighting Systems

Lighting systems are divided into four main categories based on their purpose of use:

General Lighting: Aims to distribute light evenly across the entire space (e.g., office ceiling lights).
Task Lighting: Illuminates a specific area for tasks requiring focus such as reading, assembly, or surgical procedures.
Accent Lighting: Used to highlight architectural details or artworks.
Emergency Lighting: Systems with their own battery that indicate evacuation routes during power outages or fire situations.

Lighting plays a different critical role in every aspect of modern life:

Safety and Security

Roads and Tunnels: It is vital for drivers to overcome the “black hole” effect and detect obstacles.
Crime Prevention: Well-lit streets and parks significantly reduce crime rates.
Workplace Safety: Insufficient lighting in factories is one of the leading causes of occupational accidents.

Health and Circadian Rhythm

The human body secretes hormones according to the color (Kelvin value) of light.

Blue Light (Cool White): Increases focus and reduces sleepiness (ideal for offices).
Yellow Light (Warm White): Supports melatonin production and relaxes the body.
Circadian Lighting: Smart systems that change color according to the time of day help maintain our biological clock.

Energy Efficiency and Sustainability

Approximately 15–20% of global electricity consumption is related to lighting.

LED Conversion: Provides up to 80% energy savings compared to traditional bulbs.
Sensor-Based Control: Light is used only when needed thanks to motion and daylight sensors.

In modern buildings, traditional “on-off” switches have been replaced by automation systems.

DALI (Digital Addressable Lighting Interface): A professional communication protocol where each lighting fixture can be individually controlled and fault information is transmitted to a central system.
Dimming: Saves energy by reducing artificial light intensity as daylight increases.
