The methods of calculating average luminance, contained in this Guide, cover various open bottom apertures as well as flat and drop lensed units including units, with multiple openings in the light emitting area. The candela values of interest are obtained by means of IES techniques for...
This Standard covers dimensional, maintenance, and light distribution features that permit the interchange of enclosed side-mounted luminaires for horizontal-burning high-intensity discharge (HID) lamps, solid-state lighting (LED) sources, and other light sources used in roadway and area...
A practical introduction to state-of-the-art freeform optics design for LED packages and applications By affording designers the freedom to create complex, aspherical optical surfaces with minimal or no aberrations, freeform design transcends the constraints imposed by hundreds of years of...
Many lighting design professionals associate environmental impacts only with energy use, primarily because energy considerations are so dominant in lighting. The life cycle of a lighting system is comprised of stages or phases, beginning with the extraction of raw materials and including all stages...
This standard provides physical and electrical characteristics of the group of integrally ballasted solid state lighting (SSL) lamps that have standardized characteristics. Lamps with clear, frosted, opaque, and lens end windows, and with various reflector and/or emitting coatings, are...
This Spotlight describes the process of fundamental absorption in a variety of quantum dot (QD) geometries, such as spherical, cylindrical, ellipsoidal, lens-shaped, conical, and spherical layered, including in the presence of external fields. Other topics include the effect of exciton...
This standard describes a system for the designation of integrally ballasted Solid State Lighting (SSL) lamps that have standardized characteristics. Lamps with clear, frosted, opaque, or prescription lenses, and with various reflector and/or emitting coatings are covered. Lamps covered in...
DR 1.1 This part of IEC 60079 standard specifies the requirements, testing and marking of equipment emitting optical radiation intended for use in explosive atmospheres. It also covers equipment located outside the explosive atmosphere or protected by a Type of Protection listed in IEC UL 60079-0,...
