PURPOSE:To make the luminous surface of a thinned vehicle lamp brighter and prevent observers from feeling strange by partitioning the luminous surface of the lamp into a plurality of sections, and disposing a parabolic cylindrical reflecting surface and a light source in each section, and covering all of the sections with an inner lens. CONSTITUTION:The luminous surface of a thinned vehicle lamp 1 is divided into a plurality of (at least more than two) sections at predetermined intervals and a parabolic cylindrical reflecting surface 3 and a light source 2 are disposed in each section, the reflecting surface 3 describing a parabola on its cross section perpendicular to a sectional line H; All sections are covered with the whole surface inner lens 4 processed with a linear Fresnel cut 4a along the direction perpendicular to the line H. That is the lamp 1 has its luminous surface partitioned into two approximately equal sections 1A, 1B at the line H in e.g. its horizontal direction and a light source 2 and a surface 3 are disposed in each section 1A, 1B. The surfaces 3 are all covered at their front faces with the lens 4 and an outer lens 5 both of which are formed as one side. Therefore, brightness can be enhanced and it is made possible to prevent observers from feeling strange. |
