Whatever the application, your project’s success depends on striking the best balance between economical design, cost of ownership, safety and EMC compliance, energy efficiency, ruggedness, reliability and performance. This applies to your LED power supply and other components as much as to the LEDS themselves.

These LED Lighting Scenarios Guidelines advise you on which parameters to consider, and how to specify them to ensure the best fit for your particular application. Broadly, you will see that the power supply’s packaging, operating temperature specification, shock and vibration rating and IP rating make up its ability to withstand a demanding physical environment; how its MTBF indicates its reliability in terms of the average time interval between failures; how its efficiency and power factor correction contribute to its economy of operation; and how its Constant Current or Constant Voltage configuration sets the standard of the whole LED display performance.

Overload, overvoltage and over temperature protection features, as well as safety certification, provide assurance for the safety of the power supply, its related equipment, the lighting operators and others near to the LED lighting installation.

Whatever the application, your project’s success depends on striking the best balance between a number of factors.

Why should I consider LED lighting

Why use LED lighting?

Retail lighting covers a very wide diversity of applications. And this diversity calls on different features of LED lighting technology. Great retail experiences can be created in many environments and on any scale.

A showcase cabinet displaying jewellery benefits from the LED’s single light source, which imparts sparkle to the exhibits. This also translates into a high-tech look for designer watches and similar items. A cosmetics gondola designer will appreciate the LEDs’ lack of radiated heat, while a refrigerated display cabinet benefits from uncompromised LED performance and switching in freezing conditions. On a larger scale, LED lighting schemes across entire shopping areas can closely tune the retail experience to the merchandise on show, weather conditions and other factors

Why use LED lighting?

High brightness output, high energy efficiency, low maintenance operation, controllability, ruggedness, reliability

Which LED power supply?

Consider the encapsulated, high IP rated products for outdoor environments where water, dust and shock can all become issues. Alternatively, open frame versions are available for cost- and space-effective integration into OEM luminaire products. In either case, extended temperature specifications are also important.

A Dimming function allows remote controllability of large scale lighting schemes.

Constant Current/Constant Voltage choice is important to ensure most suitable control of LED brightness distribution

Power supplies with Active Power Factor Correction will boost energy efficiency of the whole LED installation.


Why use LED lighting?

High brightness even at low temperatures, long maintenance intervals, high reliability, high energy efficiency, rugged, compact, controllable light footprint, remote controlled dimming and switching

Which LED power supply?

Packaging, encapsulation and IP ingress protection ratings are critical considerations whenever a power supply is directly mounted into street lighting equipment. Alternatively, open frame products can be used for design into OEM lighting solutions providing their own level of environmental protection. Extended temperature operation is always of importance.

Active power factor correction allows major savings in energy use.

Why use LED lighting?

High power, high controllability/dimming, high colour saturation, compact, rugged, reliable

Which LED power supply?

Packaging, encapsulation and IP ingress protection ratings are critical considerations for mobile and transportable equipment. IP67 would be preferred over IP64 in many situations. Vibration specifications are important, and extended temperature operation is often important as well.

A Constant Voltage power supply used with an external driver circuit provides the accurate control needed for these applications.
