Modernity and trends of development of automobile engineering

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