WAC Lighting showcased two innovative OLED fixture prototypes at Lightfair last month, including an OLED mini chandelier and an OLED wall sconce.
The OLED Wall Sconce features six color changeable three-inch OLEDs. The mini chandelier uses eight colorful, transparent, one-inch OLEDs, including a panel depicting the WAC Lighting logo. Each OLED draws only 0.18W; each panel is only 2 mm thick.
An OLED features a thin film display technology that began to appear in cell phones and other small-screen applications in early 2000. OLED screens consist of a series of organic layers between two electrical contacts (electrodes). OLEDs are monolithic, with each layer deposited on the other, creating a single unit. Commonly constructed on glass, OLEDs can also be fabricated on plastic and
other flexible films. OLEDs offer bright, colorful images with a wide viewing angle, low power, and high contrast ratio. They can also be made transparent, enabling them to function in heads-up displays and
even as window shades that react to sunlight. OLEDs do not need backlights, and screens can be made ultra thin. OLED’s color, speed, thinness, transparency and flexibility make it a very versatile display technology.
“Many designers and specifiers wanted to know how long it would take for WAC to integrate OLED technology into viable lighting products,” said Shelley Wang, President of WAC Lighting. “They loved the transparency of the panels, the unique quality, the dimmability, the sustainability, and operation without a heat sink. Specifiers touched the panels and were impressed to learn that the fixtures were operating at room temperature. OLED is a flat light source and heat dissipation is more efficient, in contrast to heat accumulation of LED (point-source). The panels are energy efficient, thus they turn energy to light instead of heat.”
