LED Lighting: Dialight Extended Power Supply, Philips Grocery Spotlight, Noribachi Stadium Light

February 26, 2013 By Linda Hardesty

Dialight developed a solid state power supply with an expected life of 20 years. The new power supply technology will debut on the company’s LED High Bay products for industrial and hazardous locations in Q2-2013 and will be integrated into additional Dialight fixture families this year. With a power supply efficiency increase of 7 percent from previous designs, Dialight’s new 20-year power supply will initially improve fixture lumen-per-Watt efficiency to over 110 lm/W. Compared to conventional HID lighting fixtures with bulbs that last 2 years between changes and which may fail unexpectedly due to extreme temperatures and shock or vibration, the new Dialight 20-year power supply will offer maintenance savings in environments where bulb changes require permitting, scaffolding to be erected, processes to be shut down and multiple personnel for safety supervision.

Philips Lighting launched Exact Effect, its new LED spotlight fitting for the grocery category with up to 30 percent energy savings compared to traditional spotlight applications, according to LED Inside.  Exact Effect delivers light that helps improve the look of fresh food. It is available across a range of product specifications including track and surface-mounted options. Exact Effect requires 25 percent less fixtures due to optimized light distribution that allows fixtures to be spaced wider apart from each other. It also features a choice of light levels, different Exact Beams (narrow, medium, wide and oval),different tones of white light and a rose filter to enhance the appearance of meat.

Noribachi unveiled its brightest LED light engine for outdoor stadium and intensive flood light solutions. The new light engine builds on Noribachi’s proprietary hexagonal light boards, using their modular design to create an array of 378 individual diodes that can deliver up to 66,000 lumens of light. The new product is available both as a custom LED light engine, the 378.HEX, and integrated into the Floodlight.xxl fixture, ideal for stadium illumination. Noribachi was able to create this light through thermal optimization of the LEDs, requiring a unique drive current to maximize light output while minimizing heat conduction. The ultra bright light also employs Noribachi’s method of thermal transfer including industrial gauge planar heat sinks. The 378.HEX is already in use in installations ranging from football fields to international port cargo disembarkation areas.
