Abstract
The paper analyzes the characteristics of the establishment of technical requirements for LED lamps. Folding design for LED lighting, in addition to traditional requirements that apply to luminaires with discharge lamps and incandescent lamps, further standardized: light output, primary and recovered during the life of the luminous flux, color coordinates, the general color rendering index. Resource performance and reliability was evaluated by the results of the luminous flux decline, the number of switching cycles and cyclic temperature tests. Requirements to limit glare and protecting the value of the angles of LED lighting fixtures are different from other light sources. LED fixtures must be classified into risk groups photobiological safety and energoefektivnosti classes. The aim is to analyze the characteristics of LED lamps and their conformity assessment methods, and developing proposals to establish requirements for lamps in the project standard. «Luminaires with led light source. General specifications». Item – lamp with LED light sources. The applied standard research methods of light and color characteristics LED products. On the basis of research formulated requirements for LED luminaires and measurement techniques and included in the draft standard. The analysis features that distinguish LED lighting fixtures from other light sources.
