Modernity and trends of development of automobile engineering

Abstract

Advantages of light-optical devices (LEDs) were investigated in the article. Based on the research, special attention is paid to the prospects of development of led headlights. Complicacy of car electrical equipment leads to increase of indicated efficiency and energy storage capacity and electric generators, yield increase, decrease of labor intensity maintenance operation and reconstruction. On the other hand, innovations in scientific-technological progress in electronic engineering sphere lead to rise in reluctances, so more than 30% of these reluctances account for electrical equipment. Analysis of current requirements to automobile components of lighting devices has been carried out. LEDs as automobile light sources are gaining rapid popularity. Currently, LEDs are widely used as internal light sources (instrument illumination, indicator lamps) and external ones (tail lights, additional brake lights, daytime running lights). Since 2007, white LEDs have been used as dipped- and main-beam sources. Light sources are characterized by such parameters as voltage, light power and luminous power. Derivative of these parameters is the luminous efficiency (luminous power per unit of light power), that acts as a kind of lamp’s performance and economy indicator. This article has been made in relation to the study of auto technical expertise in Moscow and Moscow Region.
