DIPPED BEAM HEADLIGHT Russian patent published in 2017 - IPC F21S8/10 

FIELD: lighting.

SUBSTANCE: dipped beam headlight includes a housing (1) with an internal cavity, an LED light source, a flat-convex lens (2), a thin plate (3) with a through slot (4) and a light reflecting ring (10). The LED light source is made in the form of a single powerful LED (8), the board (9) of which is fixed in the inner cavity of the housing (1) perpendicular to the optical axis O of the headlamp. The lower edge of the through-hole (4) of the thin plate (3) is made in the form of a broken line consisting of two rectilinear segments, one of which is horizontal and the other is tilted down at an angle of 15° to the horizon. In order to create an additional beam of light illuminating the road near the vehicle, the headlight is provided with a second thin plate (5), an insert (6) and additional LEDs (7). The second thin plate (5) is made in the form of a flat ring with a transverse horizontal baffle (11). The lower edge H of the partition (11) forms a slot (13) with the walls of the housing (1). The insert (6) is fixed in the inner cavity of the housing (1) in its lower part between the thin plate (3) with the through slot and the second thin plate (5). The additional LEDs (7) are fixed to the flat surface A of the insert (6) under the peak (14) and above the plane K passing through the focus of the lens (2) and the lower edge H of the transverse partition (11).

EFFECT: increased efficiency.
