Low Efficiency of Existing Lighting Technologies Fosters the Development of Innovative Lighting Solutions

Confronted with the low efficiency of existing lighting systems, the lighting industry is seeing rapid innovations in the development of advanced, energy-efficient, and environment-friendly solutions. In line with these developments, solid-state lighting offers the promise of high energy savings. The traditional lighting systems, however efficient, cannot match the performance levels of these lighting sources. Nevertheless, while the technology slowly emerges as a viable option for the lighting industry, there is a need for further improvement in terms of light output levels and color quality as well as a reduction in initial costs in order to make a greater impact on the vast lighting market.

This Technical Insights research service reviews advancements in the field of lighting systems and details the emergence of solid-state lighting using light emitting diodes (LEDs) and organic light emitting diodes (OLEDs). It also covers ongoing R&D in promising areas of light sources and provides information on organizations, companies, universities, research institutions, and government labs involved in these efforts.

LED and OLED Technologies see Massive Advances

LEDs are developing along different paths depending on their applications. The LED industry is focused on the development of more compact LEDS; on the other hand, the industry is also focusing on the development of high-power LEDs with large dimensions. Recent advances have led to LEDs that offer customer-specific colors. By using a converter material in the plastic molding, every conceivable hue can be achieved: be it ice blue, magenta, blue-white, or even warmer tones. However, the most interesting advancement is the development of white-lighting LED, which could have a direct impact on the massive lighting industry, conquering the area of general illumination and posing a threat to traditional light sources such as the incandescent and the fluorescent ones.

"On the other hand, customer requirements for innovative lighting that gives better control over the color, shape, and intensity of light continues to drive the demand for OLEDs as light sources," explains the analyst of this research service. "OLEDs are widely believed to be key to the next generation of solid-state white lighting, promising substantial advantages over incandescent, fluorescent, and inorganic LED devices."

Value-added Applications Drive the Market for Solid-state Lighting

The high reliability and durability provided by solid-state light sources have opened up key application areas such as decorative, signage and signaling, entertainment, display, as well as automotive lighting. LEDs, being high-brightness point sources, are most likely to dominate in the areas of signage and signaling as well as backlighting for liquid crystal displays (LCDs). OLED devices, due to their numerous benefits including self luminosity and flexibility are being used across a wide range of applications including flat panel display (FPD), cell phones, as well as other electronic applications such as personal digital assistants (PDAs) and digital cameras.

"Increasing R&D in the lighting industry is expected to make next-generation lighting sources more efficient and reliable, along with enabling them to provide increased design flexibility over conventional light sources," says the analyst. "Also, as solid-state lighting sources need to be equipped with luminaries specific to them, this is likely to lead to the formation of a whole new industry for LED luminaries."
