Published: 7/14/2008
Authors: Yuqin Zong, Yoshihiro Ohno, Pei-ting Chou
Abstract: Alternating-current (AC) driven high-power LEDs are available and used in SSL products. AC LEDs operate directly from a mains supply and thus have advantages in simplifying product design, increasing product reliability, and extending product lifetim ...

32. Color Quality and Spectra
Published: 7/1/2008
Authors: Yoshihiro Ohno, Wendy L Davis
Abstract: Color quality, including white light chromaticity and color rendering performance, as well as luminous efficacy of radiation, for illumination sources are introduced. Spectral design considerations for white LED and solid-state lighting products to ...

33. Spectral Colour Measurement, ed. by J. Schanda
Published: 1/1/2008
Author: Yoshihiro Ohno

34. Correction of Stray Light In Spectroradiometers and Imaging Instruments
Published: 7/4/2007
Authors: Yuqin Zong, Steven W Brown, Keith R. Lykke, Yoshihiro Ohno
Abstract: Measurement errors from stray light, spectral or spatial, are inevitable and are often the dominant source of error in spectroradiometers and imaging radiometers/photometers. We have developed a simple matrix method for correcting spatial stray light ...

35. Realization of total spectral radiant flux scale and calibration service at NIST
Published: 7/4/2007
Authors: Yuqin Zong, Yoshihiro Ohno

36. -Measurement of Solid-State Lighting Products,-
Published: 1/1/2007
Authors: Yoshihiro Ohno, Carl C Miller

37. -Measuring Color Quality of Light Sources,-
Published: 1/1/2007
Authors: Wendy L Davis, Yoshihiro Ohno

38. New photometer standards for low uncertainty illuminance scale realization
Published: 1/1/2007
Authors: George P Eppeldauer, Carl C Miller, Yoshihiro Ohno

39. Simple Spectral Stray Light Correction Method for Array Spectroradiometers
Published: 2/20/2006
Authors: Yuqin Zong, Steven W Brown, Bettye C Johnson, Keith R. Lykke, Yoshihiro Ohno
Abstract: In many applications, the measurement accuracy of spectroradiometers, particularly instruments with a single dispersive element, is limited by the presence of stray radiation within the instrument. A simple, practical method has been developed to co ...

40. Optical Metrology for LEDs and Solid State Lighting
Published: 2/10/2006
Author: Yoshihiro Ohno
Abstract: The performance of Light Emitting Diodes (LEDs), including efficiency, flux level, lifetime, and the variation of color, is advancing at a remarkable pace. LEDs are increasingly used for many applications including automotive, aviation, display, tran ...
