AUTOMOTIVE HEAD LAMP WITH STEPPED CIRCULATOR Russian patent published in 2016 - IPC B60Q1/04 F21S8/10 F21V31/04 

FIELD: transport.

SUBSTANCE: claimed set of inventions relates to head lamp body designs meant for passive increase in air circulation. The vehicle illumination system comprises the body, translucent diffuser and stepped circulator. The latter comprises the combination of steps and slopes extending from the rear blind toward the diffuser along the path extending, in fact, along the flow of natural air convection inside the chamber. Amplification of said natural air convection inside the illumination system involves the steps that follow. The lamp body and translucent diffuser are made. Convective airflow motion path inside the chamber developed due to the light source operation is simulated. The zones of decelerated airflow are defined within said airflow motion path. The stepped circulator trajectory and profile are shaped to interact with convective airflow the decrease in the decelerated flow zone.

EFFECT: control over air temperature inside the lamp body, decreased hot and cold zones without application of blowers.
