September 2, 2015: Applications of organic LED (OLED) are still limited to niche areas, despite its acceptance throughout the lighting industry. OLED luminaires are a source of good quality light which are efficient, versatile and stylish. Lighting designers due to its flexibility feature also prefer it as OLED panels are thin, flat, cool, and almost glare-free. Yet, OLED is taking time to be accepted widely due to its heavy upfront costs.
According to IHS Technology estimation, only 5,500 OLED luminaires were shipped in 2014, and about two-thirds of these were categorized as ?decorative and architectural lighting.? This category includes OLED applications like lighting at events, lighting for sculptural pieces in commercial spaces like museums, etc, which usually take full advantage of OLED?s aesthetic qualities.
By 2020, about 100,000 OLED luminaires will be shipped, of which 48% will be for decorative purposes. By 2020, task light shipments will increase to about 20%, estimates IHS.
Companies worldwide are also slow in adding OLED products in their portfolio or start mass production, as they are uncertain about the penetration of OLED technology, worldwide. Manufacturers are also uncertain about the development of the technology. Recently,
Philips, the largest manufacturer of OLED panels, decided to leave the OLED market, which raises doubts if this development will slow down the growth of the OLED industry.
OLED luminaire makers are, however, making efforts to add a variety of products, offering a number of products to the customers. Let?s see what are the OLED lighting products available in the market.
OLED lighting products
OLED task lights are used for a specific task, such as a desk or floor lamp. These require just two to three OLED panels, and provide a small amount of light. OLED task lights are currently used more as a decorative piece rather than for mainstream illumination. Usually, these task lights are designed to be super-thin and lightweight, which cast even glow without glare, flickering or excessive heat. Due to OLED lighting technology, these lamps do not cast multiple shadows, and emit a soothing lighting temperature, so no headaches or tired eyes.
OLED linear ceiling lights and OLED troffers are strip lights that are attached or recessed onto the ceiling and are usually used in offices particularly in meeting rooms. These are used for illumination.
OLED linear ceiling lights and OLED troffers use about eight and 10 OLED panels to emit the required illumination.
OLED decorative and architectural lights include a number of innovative products. These lights are used to highlight objects rather than used to illuminate a space. These lights include up to 1000 OLED panels per luminaire, depending on the size of the luminaire.
As the price of OLED panels will declined, the applications of OLED luminaires will change. Currently, they are being used in high-end commercial and residential properties. As a result, the future of OLED technology is totally dependent on how much the prices of OLED panels fall. According to US Department of Energy, OLED panels cost an average of $500 per thousand lumens, or kilolumen (klm). This figure needs to decrease to $20 per klm by 2020 for it to be commercially viable.
