The aim of the study is related to obtain real data for the LEDs’ thermal load and characteristics of several LED lamps types H4 and H7 for automotive headlights with different cooling system. Power consumption, temperature regimes of the LEDs’ operation, lamps’ radiation spectral distribution, and luminous flux of lamps for automobile headlights with active and passive cooling system at different ambient temperatures have been investigated. The obtained data under real conditions of operation in several cars have been verified. The results are compared with the data in promotional materials and the requirements of Regulations of the United Nations Economic Commission for Europe. Studies enable to evaluate the feasibility, advantages and disadvantages of LED lamps of this type when replacing standard halogen lamps in headlights.
