*ROAD MAP HOW TO SELECT THE BEST PERFORMING AND RELIABLE LUMINAIRES:


Lumen Output at an identifed current value (lm)

Led Efficacy (lm/W)

Colour temperature or CCT (correlated color temperature)and CRI

• Bin Selection and color shifting

Reliability (LM80 Reports & performed life tests)

Cost (lm/$ or lm/€)

 

 

**MULTI  DISCIPLINARY EFFORT


 


 

ELECTRICAL / DRIVER LOSSES (RUALIGHT LOOKS FOR AT LEAST 90% EFFICIENCY)

 

LED Driver : It is important to select right power supply based on current and voltage needed. We prefer to use a constant current power supply or voltage one + current regulator. We also check Ripple current effects. Switching on and off current peak effects also measured. To avoid hot plug (keep in mind that it damages your LED), should never disconnect the cable between leds and driver output when the luminaire is powered on.

 

As RUALIGHT, we always provide you at least 90% efficiency for high electrical efficiency. Also we care about output load of the led driver. Please notice that if it is less, you will have less efficiency. Cost matters.


 

THERMAL LOSSES

 

 

Heat Sink is the linchpin of the entire system. If this is poorly designed, all the other components can be compromised.

  


 

 

We use Aluminium injection body as heat sink material to offer you the best performance.

 


 

 

We apply air ventilation channels whenever size mattersWe offer smaller in size but bigger in performance.

 


 

 

We also follow up cold forging technology to offer you premium quality with reasonable price.

 


 

We do all the necessary thermal measurements & believe in the quality of our products. All our heatsinks are designed for best cooling performance and highest efficiency.

 

 

 

 


 

OPTICAL LOSSES

 

Optical Components: Standart components (lens & diffuser) can yellow over time and lose light; but RUALIGHT choice the best and reliable optic components that never become yellow and never loose light. We also use extra clear glass which iron particules are totaly removed. 

 

 

 

We do all the necessary optical measurements and always offer to you best market solutions.

 

 

 

All optical losses are not a matter of material selection. The application and engineering is extremely important. Gaps between COB and led holder causes dramatic optical losses. As RUALIGHT, we fasten the reflector to the holder and secure the light not to escape out and offer you higher optical effiency.

 

 

 


Looking to the future, we will continue on to research and explore in order to offer our customers the high performing products.
