Halogen Lamps

This work contains analysis of characteristics of automobile lamps by Philips, KOITO, ETI flip chip LEDs, Osram, General Electric (GE), Gtinthebox, OSLAMPledbulbs with H1, H4, H7, H11 caps: luminous flux, luminous efficacy, correlated colour temperature. Characteristics of the studied samples are analysed before the operation of the lamps. The analysis of the calculation results allows us to make a conclusion that the values of correlated colour temperature of halogen lamps are close to the parameters declared by manufacturers. The analysis of the study results has shown that, based on actual values of correlated colour temperature, it is not advisable to use LED lamps in unfavourable weather conditions (such as rain, fog, snow). The results of the study demonstrate that there is a slight dispersion of actual values of luminous flux of halogen lamps by different manufacturers. Maximum variation between values of luminous flux of different lamps does not exceed 14 %. The analysis of the measurement results has shown that actual values of luminous flux of all halogen lamps comply with the mandatory rules specified in the UN/ECE Regulation No. 37 and luminous flux of LED lamps exceeds maximum allowable value by more than 8 %. Luminous efficacy of LED lamps is higher than that of halogen lamps: more than 82 lm/W and lower power consumption. The results of the measurements have shown that power consumption of a LED automobile lamp is lower than that of similar halogen lamps by 3 times and their luminous efficacy is higher by 5 times.

The Relationship

This chapter discusses the nature and operation of mandatory and default rules in fiduciary law, arguing that loyalty is a core element of every fiduciary legal institution. Loyalty is the hallmark of fiduciary law, as it requires persons in other-regarding positions of power to perform functions selflessly, rather than selfishly. However, there are many circumstances in which a person undertakes and exercises other-regarding powers, underscoring the fact that a broad range of persons may be the subject of fiduciary law. This chapter first provides an overview of key concepts and context, focusing on the distinction between mandatory rules and default rules as well as sources of such rules in fiduciary law. It then considers fiduciary loyalty, citing examples that illustrate how a baseline of fiduciary accountability is implied by the essential nature of fiduciary legal institutions, along with the mandatory or default quality of the duties of care and good faith. The main thesis of this chapter is that loyalty is a basic constituent element of all fiduciary legal institutions. Whether fiduciary principles are mandatory involves a consideration and determination of whether the relationship or institution is inherently fiduciary as matter of law and legal classification. It also highlights the modern trend toward codification and clear legislative demarcation of mandatory and default rules in fiduciary law.
