A modular approach to LED-based luminaire design offers a number of benefits to product manufacturers including fast time to market, lower upfront engineering costs, and the ability to offer luminaires that can be serviced or upgraded in the field. Modular solid-state lighting (SSL) components enable custom luminaire design based on combinations of off-the-shelf LED light engines, module holders/brackets, drivers, optics, and other elements. The downside of modules can be less flexibility in absolutely matching a luminaire design to an application and slightly higher bill-of-materials cost relative to full custom designs. Still, modules offer benefits that will clearly make the technology a lasting part of the ongoing transition of the lighting market to SSL technology. The benefits of modular luminaire design (www.ledsmagazine.com/features/8/11/11) apply in the product development process whether the components at hand are proprietary designs or based on an evolving industry standard such as one of the Zhaga Books (www.ledsmagazine.com/features/9/7/15). This compilation includes both proprietary modular products and ones built to the new Zhaga standards that allow for interoperability of light engines, drivers, optics, and other components from multiple vendors.

Fortimo LED TDLM family by Philips

The Fortimo LED Twistable downlight module (TDLM) is a simple to install and easy to maintain modular LED light. This module is available in two color temperatures, 3000K and 4000K, includes a choice of two holders, and has a CRI of 80.The family also includes a number of different lumen-output options, such as a 1100-lm product that’s compliant with Zhaga Book 2: Socketable downlight engine. The term socketable, or twistable in the Philips product name, implies that you can mount the light engine into a bracket without the use of tools. Philips also offers a 2000-lm version that at present isn’t Zhaga compliant.

LMH2 LED modules by Cree

The proprietary Cree LMH2 LED module family delivers 95 lm/W, has a CRI of 90, and comes in color temperatures of 2700K, 3000K, 3500K, and 4000K. The module comes in either a flat lens or dome lens. Since the light source and power supply are separate, the LMH2 can be mounted and wired in a variety of different configurations. Cree recently established a Driver Compatibility Program that established approved drivers for CREE SSL modules and the LMH2 module family is initially the basis for the program (p. 21).

PrevaLED Core family by Osram

The PrevaLED Core family of light engines are compliant with Zhaga Book 3: Round light emitting surface 9mm – 23mm that is targeted at spot light applications and requires separate control gear.

The series includes six modules, and uses a twist-fit installation/replacement method, allowing the entire module to be removed in seconds. The series includes color temperature options of 2700K, 3000K, and 4000K, with a CRI of 90.

XSM 80 series LED modules by Xicato

The proprietary XSM 80 series of LED modules by Xicato rely on remote- or cold-phosphor technology to provide white light. The round modules combine blue LEDs with secondary optics coated in phosphor and Xicato says that technology delivers superior color quality. The spot-light series features LED lighting with a color temperature range of 2700K, 3000K, 3500K, and 4000K, and a CRI of 80. The efficacy for each module is above 67 lm/W, with the highest being 96 lm/W.

TECOH CFx by Megaman

The TECOH CFx twist-lock LED modules are designed in compliance with the Zhaga Book 2 specification. These modules use a multi-chip white LED array and feature a lambertian output. Because of the twist-lock design, the light engines enable luminaires that can be retained and upgraded as opposed to being replaced in the field. The modules feature a CRI of 80, and come in color temperatures of 2800K or 4000K.

7100/d1/d2-GR light engine holders by A.A.G. Stucchi
