Comprehensive Study

The article describes the results of comprehensive study aiming at increase of quality of LED luminaires and definition of the nature of changes in their correlated colour temperature (CCT) in the course of operation. Dependences of CCT of LED luminaires with remote and close location of phosphor for 10 thousand hours of operation in different electric modes were obtained; the results of comparison between the initial and final radiation spectra of the luminaires are presented; using mathematical statistics methods, variation of luminaire CCT over the service period claimed by the manufacturer is forecast; the least favourable electric operation modes with the highest CCT variation observed are defined. The obtained results have confirmed availability of the problem of variation of CCT of LED luminaires during their operation. Possible way of its resolution is application of more qualitative and therefore expensive LEDs with close proximity of phosphor or LEDs with remote phosphor. The article may be interesting both for manufacturers and consumers of LED light sources and lighting devices using them.

Institutional Researchers

While mainstream research has treated entrepreneurship as a highly individualised and agentic process, institutional researchers contend that entrepreneurship operates within a greater embedded setting. Various researchers have appealed to Giddens’ dual structure to explain an entrepreneur’s embedded-agency. According to Giddens’ dual structure, this embedded-agency consists of the rules or norms of a social group in which these rules constrain and enable an entrepreneur’s resources. Yet, despite Giddens’ contributions, Giddens is criticised for conflating the rules of this embedded setting with an entrepreneur’s resources in which neither affects the other in any significant way. By drawing on concepts of the Austrian entrepreneur and embeddedness, a theory of institutional entrepreneurship is developed to address this conflation problem. This institutional entrepreneurship offers an embedded-agency to explain how an entrepreneur can create, maintain and disrupt their embedded social settings. This embedded-agency addresses Giddens’ conflation problem and broadens the agent-centric focus of institutional entrepreneurship research.
