Brilliant Colors for Brilliant Products - OSLON SSL 80° and 150° with CRI 95

Light and color have a profound effect on our well-being and on the atmosphere of a room.  Correct color rendering is an important aspect of good lighting. A high color rendering index (CRI) means that objects appear in their “true” colors to the human eye. With its high-CRI OSLON 80° and 150° OSRAM Opto Semiconductors is closing in on perfection. As in natural daylight (CRI 100) all objects illuminated with these OSLON versions appear in their natural colors. This is thanks to the excellent color rendering index, typically 95. Realistic color rendering is important particularly in shops so that the goods purchased inside the shop look as good as they do outside in daylight. Items in exhibitions and pictures in museums should be presented in light that allows their true colors to shine out. Natural color rendering is also in demand in other general illumination applications, for example in the home. Despite this high CRI, every version of OSLON offers efficiency that stands comparison.

The high quality of light remains stable for a long period of time. The LED achieve a CRI value greater than 90 under all application conditions. The R values for color rendering are greater than 90 for R9 (red) as well as for R13 (skin tones). The two high-CRI LEDs are available in color temperatures of 2700 K, 3000 K (residential, museums), 3500 K and 4000 K (shop lighting).

The different OSLON SSL products precisely match the various requirements posed by different applications:
  • For premium applications indoors where natural color rendering is required LED with a very high CRI (CRI 95) are recommended even  though the efficiency may be slightly lower (typically 65 lm/W at 3000 K/350 mA).
  • Standard lighting systems, such as those installed in offices, are often best served by LEDs that strike a balance between CRI (CRI 82) and efficiency (typically 81 lm/W at 3000 K/350 mA).
  • In the outdoor and industrial sectors CRI often plays a minor role (CRI 70), but here there are benefits to be had from much higher efficiency (typically 100 lm/W at 5000 K/350 mA).

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa...

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin...

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
