CHOICE OF THE RIGHT LED LIGHTING MODULE TECHNOLOGY/TYPE DEPENDS ON REQUIREMENTS AT APPLICATION LEVEL!
Growth of the LED industry initially came from small display applications and was driven forward by larger LCDs. Since 2012, most companies have been participating in the ultimate application for the LED business, general lighting. Now, for Solid State Lighting (SSL) to grow, the industry expects strong price decreases through development of new LED platforms.
Standard LED lighting modules represent the main answer to SSL industry needs. Such modules are a basic ‘plug and play’ component of the lighting system that allow new luminaires to be easily and rapidly introduced to the market. These modules significantly contribute to system performance, quality and safety.
Many LED lighting modules are currently available, including mid-power and high-power modules. Mid-power LED modules offer low power consumption and high flux whereas high-power LED modules deliver more flux and offer a larger Light Emitting Surface (LES). Chip-on-board (COB) LED modules provide a compromise between size of light, LES, flux power and power consumption. However they need additional components to give the light effect desired, such as clamp holders and reflectors. The choice of the LED module technology will depend on an application’s system requirements with regards to power consumption, LES and light flux...

• The Zhaga Consortium is an organization enabling the
interchangeability of LED light sources made by different
manufacturers.
• Zhaga establishes interface specifications for different form factors.
For each form factor, Zhaga’s specifications enable interchange of
components from different suppliers.
• Zhaga define following interfaces:
• Mechanical interface.
• Photometric interface.
• Thermal interface.
• Electrical interface.

• Strategy of middle power
LED module manufacturers
is driven by cost aspect and
based on mass production
of middle power LEDs (i.e.,
economy of scale), resulting
in a standard offer with
limited diversity and flux
range.
• High power modules
address applications having
different needs (or
combinations of needs):
• Need XX.
• Need XX.
• Need XX.
• The market is characterized
by less volumes, but higher
value and selling price.
