Understanding Photometric Reports for SSL Products
ثبت نشده
چکیده
IES LM-79-08: IES Approved Method for the Electrical and Photometric Measurements of Solid-State Lighting Products. Describes the method of absolute photometry for LED luminaires and integral replacement lamps, and associated electrical measurements. Provides performance data (i.e., light output and efficacy, light distribution, and color characteristics) for the entire, integrated product—versus separate results for the light source (“lamp”) and luminaire provided by traditional relative photometry.

Comparing photometric distributions
The distribution of light from architectural luminaires and other light sources is characterized by photometric distribution reports. These reports enumerate the measured luminous intensities for a sparse set of vertical and horizontal angles about the luminaire (which is modeled as a point light source). Illumination engineers and lighting specifiers often need to compare hundreds of similar p...

Effect of semihydrogenated vegetable oil (shortening) and sodium stearoyl lactylate (SSL) on retarding Barbari bread staling was investigated in this study. Three levels of 2, 3 and 4 percent shortening and SSL in two levels of 0.5 and 1 percent of flour were used in this research. Treatments included control sample (without shortening and SSL), bread with only shortening, bread with only SSL, ...
متن کاملSSL Technology Fact Sheet: Flicker
The advancement of commercially available LED products is reopening discussions on how the performance of light sources should be evaluated. This includes questions about the necessity of characterizing light sources for fl icker, the (potentially visible) temporal variation of emitted light. While conventional light sources operating on alternating current (AC) modulate light output, the varie...

متن کاملNew Framework of Sustainable Indicators for Outdoor LED (Light Emitting Diodes) Lighting and SSL (Solid State Lighting)
Light emitting diodes (LEDs) and SSL (solid state lighting) are relatively new light sources, but are already widely applied for outdoor lighting. Despite this, there is little available information allowing planners and designers to evaluate and weigh different sustainability aspects of LED/SSL lighting when making decisions. Based on a literature review, this paper proposes a framework of sus...
