Developed jointly by the American National Standards Institute (ANSI) and the Lighting Engineering Society (IES), the ANSI/IES LM-79-19 standard provides repeatable accurate measurements of total light, radiant, or photon flux, while performing electrical power, system efficiency, luminous, luminous or photon flux. Intensity distribution and the procedures to be followed and precautions to be followed to determine the color amounts and spectrum of solid-state lighting products for lighting purposes under standard conditions are explained. This approved method covers LED luminaires, OLED luminaires, integrated LED lamps, integrated OLED lamps, non-integrated LED lamps and LED light engines powered by a manufacturer's identification number or an identified driver. These are referred to as solid state lighting products or tested devices within the framework of the standard. Except for non-integrated LED lamps solid state lighting products are designed to be connected directly to alternating current mains power or to a direct current voltage power source for operation.
Solid-state lighting uses electrical filaments, plasma (used in arc lamps such as fluorescent lamps) or gas as the lighting source, or semiconductor light-emitting diodes (LEDs), organic light-emitting diodes (OLEDs), or polymer light-emitting diodes (PLED') It is a type of lighting that uses
The main advantages of solid state lighting are: small size, ease of control, unidirectional distribution, very high and comparable color rendering compared to high fluorescent lamps with cold beam and high color rendering index, lower energy usage compared to incandescent lamps, high performance in cold environments.
Solid state lighting is a new technology. New materials and technologies offer significant improvements in efficiency compared to traditional incandescent lighting. On the other hand, it brings some difficulties for end users, designers, lighting industry and regulatory authorities. Because using solid state lighting products, it's always just unplugging one lamp and plugging in the other. It's not an issue.
Optical and electrical measurement services for solid state lighting products within the scope of ANSI/IES LM-79-19 standard, with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it has given for businesses in various sectors. also gives.
