Proposal of basic electrical driving circuitries

There are many different LED systems and setups and each might need a different wayto drive the LED regarding the size of the LED, the space and the cost of the solution.We can make a proposal for the basic electrical driving circuitries tailored to the need ofthe application.

Verif ication of Electrical Designs by Simulation

If there are doubts in the electrical design especially if a resistive driving solution hasbeen chosen, we have the capability to verify by electrical simulation that the currentsdo not exceed the specification of the LED component.

LED Outdoor lighting

Technology status

LED Feature Impact for LED outdoor lighting

High luminaire efficacy- reduced power consumption

- faster return of invest

High l ifet ime / robustness - longer maintenance intervals and faster ROI

Directional light- reduced power consumption

- less light pollution ( light where its needed )

Choice of light quality- improved visual comfort and safety

- application specific light quality

Compact and dimmable

- new luminaire designs and implementations

- reduced power consumption possible by

dimming, sensors, etc.

Mesopic vision

Mesopic factor:

During nighttime the human eye percepts neitherphotopic nor scotopic brightness. The area inbetween is called mesopic. The mesopic factordescribes the percepted brightness at a givensurrounding luminance. For street lighting conditionswe assume 0,3cd/m.

S/P-Ratio:

Scotopic weighted radiation spectrum V() divided byphotopic weighted radiation spectrum V().
