OLED vs LED Lighting

2. května 2013 v 5:10 |  solar photovoltaic system
The lighting industry is a large, global and yet fragmented market place. The fragmentation is driven both by technology differentiation and customer need diversity. The technologies vying for market share include incandescent lamp, compact fluorescent lamp (CFL), halogen lamp, light-emitting diodes (LEDs) and, most recently, organic light emitting diodes (OLED). The target markets are also very diverse, each service different needs and demanding different price points. These markets include residential, architectural, hospitality, shop, industrial, office, and outdoor.

OLED and LED lighting are both solid-state technologies and offer overlapping value propositions per market segment. They will therefore compete directly in many instances. LED lighting has come a long way and offers a better performance than OLEDs, and that at a lower cost. OLED lighting will therefore only gain market success if it clearly defines its unique selling points and carves out initial market niches.

This report is divided into two part: (a) technology and (b) market assessment. The first offers a comprehensive yet detailed overview of both LED and OLED lighting, going through fabrication processes, material compositions, technology roadmaps, and key players. The device attributes of each technology are also critically assessed, examining parameters such as colour warmth and controllability, flexibility, efficiency, surface emission, lifetime, wafer size, and luminaire design.

The second section offers a blunt market assessment. Detailed cost projection roadmaps are developed, factoring in estimated cost evolution of the integrated substrates, encapsulation layers and materials. Changes in system configuration and material composition required to enable the cost roadmaps are outlined. We also factor in production costs including capital and labour.

The value proposition of OLEDs for all market segments is critically analysed. For each assessment, IDTechEx Research examines parameters such as light quality, form factor, technology mix diversity, price sensitivity, light controllability, lifetime and light intensity. The report also rigorously compares the performance of OLED and LED devices using the above parameters.

IDTechEx Research also develops detailed market forecasts. Here, we estimate the market share of OLEDs per lighting market segment, calculate the total lighting area per sector, estimate the lumen output per segment, and forecast the equivalent number of units sold per sector. Combining all our analysis, we forecast the monetary value of the market at module level per market segment.

A technology solutions company, announced it has expanded its light-emitting diode (LED) bulb product portfolio to include both PAR30 and BR30 bulbs. Like the previously introduced Rambus A19 bulb, the two new products are built on the company's MicroLens optical technology, provide energy efficiency and broad dimmer compatibility and are designed to provide effective thermal management.

The new Rambus PAR30 (65-watt equivalent) and BR30 (75-watt equivalent) LED bulbs are designed to address the energy efficiency, reduced glare and lighting experience needs of consumers, property managers, retailers, lighting designers and specifiers across a wide range of indoor and outdoor lighting applications. Both the Rambus PAR30 and BR30 LED bulbs exceed the lumen output specified by Energy Star. In addition, the micro-electronics improve dimmability. The full portfolio of Rambus LED bulbs are currently available for commercial orders, with shipments expected to start by the third quarter of this year.
