Assessment of Solid State Lighting, Phase 2 -

Completed

Topics

The National Research Council (NRC) appoints a committee and conducts a study of the status of advanced solid state lighting (SSL). The report considered the basic science and engineering needed to improve the quality of light and the durability of the solid-state devices and phosphors that emit the light.

About Past Events

Description

The National Research Council (NRC) will appoint a committee to carry out this study and provide a report on the status of advanced solid state lighting (SSL). The report will update the findings of the 2013 NRC study. Specifically, the committee will focus on the following overarching tasks.
1) Commercialization of Solid-State Lighting. The committee will assess the market trends for LEDs and OLEDs including sales volume of different applications and the cost and performance of the luminaire and its components. The committee will evaluate to what extent problems are being encountered with lighting quality (color shift, lumen depreciation, etc.); durability; power factor and generation of harmonics; and integration with controls (e.g., dimmer switches) and will recommend improvements.
2) Improvements to Current Technology. The committee will consider advancements that could occur in LEDs, especially in OLEDs, as an increasing number of applications are being pursued and larger volumes are being deployed. The committee will assess how the R&D and other activities supported by DOE’s Solid State Lighting Program can contribute to improvements such as greater efficacies of up to 250 lpw.
3) Manufacturing. The committee willcomment on the challenges related to high-volume, low cost manufacturing of SSLs. The committee will evaluate the domestic and foreign manufacturing supply chains (raw materials, epitaxy, wafer and chip manufacture, packaging, device assembly, etc.) for LEDs and for OLEDs, as well as the supporting research and investment infrastructure. Looking at the supply chain in particular, the committee will consider which countries dominate particular aspects of the chain (e.g., China and epitaxy) and will identify opportunities for the U.S. industry and possible leveraging investments by the DOE Solid State Lighting Program.

The committee will provide a report to the U.S. Department of Energy, the Committee on Energy and Commerce of the House of Representatives, and the Committee on Energy and Natural Resources of the Senate.

Conflict of Interest Disclosure

Disclosure of Conflict of Interest: Iain Black

In accordance with Section 15 of the Federal Advisory Committee Act, the "Academy shall make its best efforts to ensure that no individual appointed to serve on [a] committee has a conflict of interest that is relevant to the functions to be performed, unless such conflict is promptly and publicly disclosed and the Academy determines that the conflict is unavoidable." A conflict of interest refers to an interest, ordinarily financial, of an individual that could be directly affected by the work of the committee. As specified in the Academy's policy and procedures (http://www.nationalacademies.org/coi/index.html), an objective determination is made for each provisionally appointed committee member whether or not a conflict of interest exists given the facts of the individual's financial and other interests and the task being undertaken by the committee. A determination of a conflict of interest for an individual is not an assessment of that individual's actual behavior or character or ability to act objectively despite the conflicting interest.

We have concluded that for this committee to accomplish the tasks for which it was established its membership must include among others, at least one person who is currently engaged in the manufacture of solid-state lighting devices.

To meet the need for this expertise and experience, Mr. Iain Black is proposed for appointment to the committee even though we have concluded that he has a conflict of interest because he is employed by Lumileds, a leading developer and large-scale manufacturer of solid-state lighting.

Mr. Black has extensive and recent experience with manufacturing operations and with developing solutions that integrate the basic LED emitter into systems that include optics and electronics. In addition to his expertise in overseeing technical advances, Mr. Black has had the practical experience of being general manager of a manufacturing plant operating at large-scale. This familiarity with current industry approaches to manufacturing is critical for the committee in meeting its task. We believe that Mr. Black can serve effectively as a member of the committee and that the committee can produce an objective report, taking into account the composition of the committee, the work to be performed, and the procedures to be followed in completing the work.

After an extensive search, we have been unable to find another individual with the equivalent combination of current practical experience and expertise as Mr. Black who does not have a similar conflict of interest. Therefore, we have concluded that this potential conflict is unavoidable.
