The filament of the light source is designed to be at the focus of the paraboloid of the mirror, and is reflected by the mirror to form a beam parallel to the optical axis. The light beam diffuses and refracts the beam to form a wide horizontal beam, and the light shape and illumination are in compliance with regulatory requirements. The hood in the front fog lamp is used to cover the light of the filament to the upper half of the mirror, so that the light distribution has a clear cut-off line, that is, the upper and lower sides are clear. It should be as dark as possible in the visible area above the light-gloss edge, and the horizontal spread angle should be 50° on both sides of the lower bright area to form a bright area of left and right lateral to meet the dazzling and safe driving. Provide good lighting conditions.
