US Department of Energy 2015 SSL research and development program exposure

         According to reports, the US Department of Energy (DOE) recently released the 2015 solid-state lighting (SSL) R & D program, the merger of the multi-year program plan and SSL manufacturing blueprints previously announced.
The new SSL research planning documents emphasize manufacturing LED and OLED roadmap, color uniformity problems and manufacturing advances to solve the problem and so on. The new report also noted that the current global illumination device SSL accounted for less than 10%, for many years, SSL technology to reduce energy consumption will continue to strive to make a huge impact in the field, the United States Department of Energy predicts that by 2030, LED technology will help Provincial 26.1 billion kWh, SSL accounting for an increase of 40%.
DOE has also developed a 2020 target efficacy or system-level lighting 200 lm / W, the report noted that greater efficiency LED package increasingly difficult to achieve, it is recommended to focus on R & D focus on efficiency recession and narrow linewidth the down-converter materials can provide additional benefits.
This new research report focusing SSL LED and OLED, etc. in addition to the phosphor, LED focus of packaging materials, the new transmitter architecture, integrated transmitter, the new method include system-level elements and lighting design. OLED, although the efficiency and light output significantly lags behind the LED, but the US Department of Energy is still optimistic about its inherent qualities diffuse light source, continue to tap the potential of technology. OLED R & D focus include materials research, the light extraction efficiency, lighting development, increase production and adopt a flexible substrate manufacturing.
In the new report, the US Department of Energy also urges the symbiotic technology industry research and development work to LED and OLED based. In addition, the DOE also urged the people-centered illumination and overall lighting quality.
Brief summary of the top level of SSL research goal, the Department of Energy forecast, LED will be close to warm cool white element 250 lumens / watt level in 2025, a new hybrid approach may be used as mixed monochrome emission and the phosphor conversion device. Effectiveness of aid projects the agency may allow OLED achieve 160 lm / W in 2020, and eventually reach 190 lumens / watt.
