Sharp Launches High-Color-Rendering LED Range

Sharp is supplementing its LED lighting portfolio with three Doubledome white, high-colour-rendering (HCR), high-performance LEDs. The Doubledome LEDs already provide suitable light for energy efficient lighting without secondary optics. The light conversion layer of the Doubledome LEDs is based on a two-phase development procedure especially developed by Sharp for this purpose. A layer of phosphorous for the conversion of white light is applied in a first step. The installation of the globe top made from transparent silicone in a second step makes light extraction possible without spreading loss.

A high-quality ceramic plate serves as the LED carrier material instead of the plastic materials that are traditionally used. Sharp said this allows efficient heat dissipation and helps to keep the required cooling element small. The HCR LEDs reach the high colour rending index (CRI) value of 85 through the combination of blue LEDs with a blend of green and red phosphorous. The SMD LEDs from the GM2BBxxBM0C series ensure high colour fastness and attention to detail, which are vital everywhere where light must distort the depiction of objects.

Typical applications for HCR LEDs include photography, shop windows, shop lighting and merchandise presentation, as well as in medical technology. As different applications also require different lighting concepts, the Doubledome series is available in three different shades of white: 'Warm White' with 3,000K, 'Natural White' with 4,000K and 'Pure White' with 5,000K. In combination with the high CRI values, the HCR LEDs from Sharp are approximately equivalent to conventional fluorescent tubes with regard to their efficiency, colour temperature and CRI. The HCR LEDs therefore already correspond to the requirements of the Energy Star programme.

Sharp's Doubledome LEDs, which are solderable according to the reflow method, are scarcely bigger than the head of a match. Due to its low space requirements of 2.8 x 2.8 x 1.9mm, the LED series GM2BBxxBM0C is suitable for a range of applications that require a high degree of brightness in combination with compact design. The 'Double Dome' series is already tried and tested and used in large volumes in the LED backlighting of LCD televisions and is particularly predestined for applications in surface lighting such as the ceiling lighting of office rooms and factories. Other typical application areas include sales area lighting, street lighting, architectural lighting and display lighting.

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.
