Updated:

Manufacturers can produce lighting fixtures that are more aesthetically beautiful, energy-efficient, and adaptable by drastically shrinking the size of LED components.

 

The ability to incorporate lighting into a wider range of applications, from consumer electronics to architectural designs, has been made possible by this decreasing size.

 

The recent developments in reducing the size of LED lighting components are examined on this page.

6. Sector-Based LED Module Design for Compact and Homogeneous Light Emission

TRIDONIC JENNERSDORF GMBH, 2019

LED module for emitting mixed light, preferably white light, that can be used in lamps with small reflector sizes. The LED module has a circular light-emitting zone divided into flat sectors, like slices of a pie. Each sector can emit a different light spectrum. Phosphor can be added to the potting compound between the sectors to create white light. This allows producing a homogeneous mixed light from individual sector emissions. The circular sector design allows a small light-emitting zone suitable for small reflector lamps.
