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.

Infusion LED modules by GE Lighting
GE Lighting’s Infusion LED modules offer a large range of lumen packages, which range from 850 lm to 4,500 lm. The modules are designed for compatibility with Zhaga Book 5: Socketable engine with separate gear, although the modules aren’t yet on Zhaga’s list of certified products. 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.

S-Class street lighting module by Carclo
Modular light engines comes in many form factors – driven in part by application – and this new S-Class module from Carclo is designed specifically for street-lighting applications. Carclo is an optics specialists and this is the company's first complete light-engine offering. The S-Class is a proprietary design but still includes the thermal, optical, and electronic elements that can accelerate the luminaire development cycle. Carclo views the entry into the light-engine business in part as a way to provide customers easier access to its optics.
