LED which is running at a temperature

The RCD series have two independent dimming inputs: a PWM control that allows simple interfacing with microprocessors and digital controllers and an analogue voltage input that is suitable for lighting controllers or rheostat dimmers. Both dimming inputs are linear and the dimming range covers 0%-100%. The PWM input can also be used to shut down the converter to draw only 200μA from the supply.Incorporated in 1975 led high bay light Electronic GmbH originally was a supplier for high precision metal- film- resistors and- networks, becoming a pioneer for miniature DC/DC-converters in the mid 1980’s. Today RECOM is a leading supplier of converters in the power range from 0.25 Watt to 60 Watt and above. Their core focus- development & design, production and marketing span three continents - America, Europe and Asia, thereby ensuring close proximity to the customer base worldwide.

The Energy Star guideline for lumen maintenance requires that after actually running for 6,000 hours, an LED which is running at a temperature that is equivalent to what it would be in a luminaire, must maintains 91.8% of its brightness, or 94.1% of its brightness for outdoor commercial or residential settings. However, after an actual test of 6,000 hours for Luxeon Rebel LEDs running at 350 mA at 55 degrees Celsius, the LEDs maintained 99% of their lumen output.

The results reinforce the superior lumen maintenance performance that has been a hallmark of Luxeon LEDs since they were introduced in 2000, They reflect the ability of the materials used to build Luxeon LEDs — including those used in the Epitaxial process, the phosphors, and the lens and packaging materials — to withstand the rigors of use and the elements to which they might be exposed under a variety of conditions without degrading the led high bay light output too rapidly.Neo Neon’s LED Streetlights in Sweden were firstly installed in Kjellbergsgatan, J?nk?ping Municipality, and have now been in use for two years. The reaction of the public and the Municipality has been very positive. Because of many successful projects completed by RBIecolight, Neo-Neon now has many projects which they are evaluating with clients in a number of different countries.
