As in any rapidly evolving industry, the “language” for certain concepts, components, systems, applications, etc. is not well established and consistent throughout the industry. This fact has created confusion between vendors, engineers, consumers, manufacturers, and others. LumaStream believes it is important to define the language we use within our company and throughout our website. As naming conventions become standardized we will update these definitions.
- Binning and labeling is the process of separating LEDs based on their various characteristics and assigning them with a specific bin code. LEDs with the same characteristics are placed on a reel. White LEDs are sorted by color and brightness. Color LEDs are sorted by dominant wavelength and brightness. LumaStream relies on Phillips, an industry partner, for precise binning spec’s of the Phillips Rebel chip.
- CALiPER is Department of Energy’s (DOE) SSL Commercially Available LED Product Evaluation and Reporting (CALiPER) program independently tests and provides unbiased information on the performance of commercially available SSL products. Working the public interest the DOE publishes test reports, technical information, and summaries of manufacturer’s products and is intended solely for the benefit of the public, in order to help buyers, specifiers, testing laboratories, energy experts and others make informed decisions about SSL products and related technologies.
- Correlated Color Temperature (CCT) is the measure used to describe the relative color appearance of a white light source. CCT indicates whether a light source appears more yellow/gold/orange or more blue, in terms of the range of available shades of “white.” CCT is given in kelvins (unit of absolute temperature). Note! Cool White targets a typical CCT between 10,000k and 45ook; Neutral White targets a typical CCT between 4,500K and 3,500K; Warm White targets a typical CCT between 3,500K to 2,540K.
- Color Rendering Index (CRI) indicates how well a light source renders colors of people and objects, compared to a reference source of like color temperature.
- Integration is the ‘marrying’ of lighting and lighting control components. Integration can set proper light levels and atmosphere for office video-conferencing or create comfortable dynamic scenes within a residential setting. A design-build LumaStream SSL system and can enhance both modern lifestyles and businesses at the simple touch of a button offering convenience, energy-savings and reduced operating costs.
- Interface is the human mechanism for interacting with the lighting system, typically, a computer or an in-the-wall control panel.
- LED Light Engine is a subsystem of an LED luminaire that includes one or more LED packages, or an LED array, or an LED module; an LED driver; electrical and mechanical interfaces; and an integral heat sink to provide thermal dissipation. An LED light engine may be designed to accept additional components that provide aesthetic, optical, and environmental control (other than thermal dissipation). An LED light engine is designed to connect to the branch circuit. [from IESNA RP- 16-05 revision draft, March 2008].”
- Lumen depreciation is the decrease in lumen output that occurs as a lamp is operated. For most light sources, the lamp fails before significant lumen depreciation occurs (an outdated exception is mercury vapor lamps). Because LEDs can continue to operate at very low light levels, LED life is usually defined as lumen depreciation to a particular point, such as 70% of initial lumens.
- Luminous efficacy is the most commonly used measure of the energy efficiency of a light source. It is stated in lumens per watt (lm/w), indicating the amount of light a light source produces for each watt of electricity consumed.
- Retrofit as pertaining to lighting means to substitute new or modernized systems for older lighting equipment. LumaStream design-build systems can incorporate partial or complete retrofit and upgrade solutions for hospitality, retail, museums & art galleries and landscape lighting applications.
- Scalability is a desirable property and benefit of a solid-state lighting system whereby capabilities can be put in place to successfully accommodate future lighting needs. LumaStream systems provide for smooth transition in solving the complexities of expanding lighting needs and system control.
- Scalable System means being absolute about critical factors and asking the right questions should scalability become evident. Confronting scalability issues such as increased demand for lighting and changing control needs is LumaStream’s forte. Helping lighting clients with identifying the specifics of ‘buying scalability‘ is what we do.
- White Light comprises light from all the frequency bands in the visible spectral range from 380nm to 780nm. Hence, it is a combination of red, orange, yellow, green, blue, indigo, and violet.
