LED Linear Ambient Market Share Projected At 83-94% In 4 Northeast States

Utility programs in four Northeast states have evaluated LED linear ambient market share. The utility consulting firm, DNV, performed all four rebate program evaluation reports for Rhode Island, Massachusetts, Connecticut, and New Jersey. Projected LED linear ambient market share for 2023 ranges from 83% to 94%. Market shares this high may eventually make it difficult [...]

Running IR LEDs In Reverse For Active Cooling

The December issue of designing lighting (dl) magazine has an interesting story about recent research into running infrared (IR) LEDs in reverse polarity to create active cooling. One caveat for this approach to work is that the object to be cooled has to be incredibly close to the IR LED — less than 1 wavelength’s [...]

The Status Of Quantum-Dot LEDs

Quantum-dot LEDs (QD-LEDs) are based on quantum dots (QDs), semiconductor particles just a few nanometers in size. Because of their extremely small size, their behaviour is governed by quantum mechanics. By ‘exciting’ quantum dots with electricity or driving radiation, they can be induced to emit light, the color of which is determined by the size [...]

A Look At The Color-Mixed White LED Future

In February 2022, the US DOE released its 2022 SSL Research & Development Opportunities report. While the report covers many promising directions for SSL R&D, one of the most significant evolutions predicted for LED light sources is the shift from phosphor-converted white LEDs (PC-LED) to color-mixed white LEDs (CM-LED).

Product Monday: LumenPulse Launches Mix-At-Source Color-Changing Technology

Lumenpulse has introduced a new proprietary technology, Opticolor, to its color-changing projector products portfolio. The patent-pending Opticolor technology mixes color at the source, at the LED package level, within the LED optic, allowing for ultra near-field color blending, exceptional quality of light, as well as unrivaled color consistency and uniformity.

Product Monday: New Category Of LED Filament Lamps For HID Replacement

A new category of HID replacement lamps has arrived that are definitely not “corn cobs.” Their high lumen output LED filament lamps in traditional HID lamp form factors. I’ve found wattages as high as 42W (LED) that claim to replace up to 175W Metal Halide or HPS system watts (HID lamp + ballast), providing up to 75% energy savings.

Massachusetts LED Study Projects High C&I LED Adoption Rates

Last year, an evaluation report by DNV was published about Massachusetts’ commercial & industrial lighting rebate programs. The report projected some LED adoption rates significantly higher than DOE’s predictions for the US, as a whole.

LRC Proposes Two Metrics To Predict LED Product Life

Arguably, the biggest gap in LED metrics is a product lifetime metric and test procedure. Currently, the industry is rife with fraudulent emitter life claims used as LED system product life claims (lamps, luminaires, and engines).
