LED + SSL

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.

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.

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.

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).

The U.S. Department of Energy (DOE) Building Technologies Office (BTO), within the Office of Energy Efficiency and Renewable Energy (EERE), has published two new reports, 2022 DOE SSL Manufacturing Status & Opportunities and  Solid-State Lighting R&D Opportunities.

Researchers have discovered a new method of generating long-wavelength (red, orange, and yellow) light through the use of intrinsic defects in semiconducting materials, with potential applications as direct light emitters in commercial light sources and displays.
