Dec 23, 2015: Several LED lighting modules are available in the market, including mid-power and high-power modules. Mid-power LED modules offer low power consumption, high flux in association to large led count and lighting surfaces while high-power LED modules provide more flux and in smaller light emitting surface (LES). COB LED modules offer something which is in between size of light, LES, flux power and power consumption, says Joel Thomé, PISEO?s General Manager.
But all these need supplementary components to provide the light effect desired, like clamp holders and optics. The choice of the LED module technology depends on system requirements of an application with regards to power consumption, LES and light flux.
According to Pars Mukish, Business Unit Manager, LED, OLED and Sapphire at Yole: ?The key benefits to lighting integrators of using LED modules cover faster product development cycles, less complexity for integration as well as the management of high level parameters that is directly done by the LED module supplier.? But the choice of the module needs a thorough knowledge and understanding of the three key areas: application, technology and system architecture. These factors are related to each other. As a result, provisions of the key functions of the module, including thermal management, optical design and power supply, should be studied carefully to make sure the right components and materials are used.
Initially, growth of the LED industry came from small display applications and was taken forward by larger LCDs. Most of the companies have been participating in the ultimate application for the LED business and general lighting since 2012. To solid-state lighting to grow, the industry hopes fair price decreases through development of new LED platforms.
Total standardization of these sub-systems is still not easy because integration of LED modules must follow certain rules in areas like design and electrical insulation. So, the Zhaga consortium has been created to provide guidelines for interchangeability of LED light sources produced by manufacturers. Though standardization will further reduce development and maintenance, it will also lessen the possibility of differentiation between suppliers.
A good number of LED lighting module suppliers are packaged LED manufacturers, who have used vertical integration to grab more value within the supply chain. They have a better competitive advantage as far as mastering the LED binning strategy is concerned. Some other types of players are also in this business. They want to diversify their activities and/or define new strategies to support their primary business. These are: LED luminaire, LED driver, optic, connector, heatsink ? manufacturers.
PISEO and Yole highlight the emergence of flexible LED strips under this new report. Flexible LED strips correspond to a new form of LED lighting module, which can also be used as LED lighting systems. Initially, Asian manufacturers developed it for the Asian market. But now they are spreading globally.
Pierrick Boulay, Technology & Market Analyst, LED, OLED and Lighting Systems at Yole, says, ?These modules allow new applications as they have design flexibility and are mostly driven by indirect lighting applications and high-end applications. In future, we expect these modules to continue penetrating indoor lighting applications like residential lighting and commercial lighting.? Yole?s report consists of a comprehensive survey of flexible LED strips, describing technology, market and industry trends.
