LEDs are a proven success in traffic signals and exit signs and they are now competing for market share in automotive and aeronautical applications, signage, “architainment”, architectural, contour and roadway lighting. The list of applications is exploding due to improved brightness and power for both white and colored LEDs. These new uses include backlighting for large and small displays. For example, colored screens in cell phones will increase from the current 10-12% to nearly 100% in 3-4 years. The potential for LEDs in these markets is substantial. LEDs are also advancing into the $15 billion global general illumination market.
Semiconductor manufacturers are introducing powerful green and blue LEDs with lower cost solutions--such as gallium nitride on silicon wafers--to strongly compete with silicon carbide (SiC) and sapphire-based LEDs. The elusive goal of an effective white LED has come closer in the past year with the introduction of UV LEDs which permit a range of opportunities in general lighting, cell phones and PDAs, and larger display applications.
Technical hurdles still need to be overcome before LEDs become a truly viable option for the general illumination market. Although cost has decreased considerably in the last two years, these cost decreases must accelerate before LEDs can replace incandescent lamps in more applications. Other problems include finding the right “white” light with improved color rendering, integrating efficient optics and fixture design, and developing thermal resistant packaging. Industry standardization and universally accepted testing equipment are still years away. Overall though, the future for LEDs is getting brighter in every possible way.
