NOTE:
As for all electrical devices, LEDs will degrade through time with a consequent reduction in their luminosity.
This explains why it is almost impossible to obtain identical photometric performances between two different
LED devices with different operating lifetime. LEDs lifespan varies greatly and is the result of a complex
formula which considers multiple factors such as operating efficiency, continuous operating time, and
environment conditions (e.g., ambient temperature).
All semi-conductor devices, such as LEDs, are subject to inherent variables related to their technical features.
In order to improve output and performance uniformity, D.T.S. Illuminazione Srl uses selected LEDs
considering the aforementioned factors, reducing to the minimum variations in output luminosity, color
temperature and tone shift in color between devices.
4.1 Protection against over-temperature
The DOCTUS.D incorporate a system for measuring and controlling the temperature of the LED circuit.
If the internal temperature exceeds 70 °C, the intensity of the LED driving current will be reduced until the
temperature is restored and then maintained below the indicated value.
If the internal temperature exceeds 87 °C, the light will be completely turned off and will automatically return to
operate when the temperature drops below 80 °C.
5 Installation
5.1 Things to Consider
Plan the setup before mounting the product. This will guarantee a successful and durable installation. It is
recommended to carefully consider the following:
•
Atmospheric conditions and ambient temperature of the installation site.
• Installation distances, adequate cable length and section.
•
The quantity and model of the devices, and their power supply units.
• A correct protection from overvoltage.
•
A correct orientation of the light beam.
