VEHICLE LIGHT

Japanese Patent JP3839235

B2

PROBLEM TO BE SOLVED: To provide a vehicle light having a light source formed of plural LEDs in which is lighting, the light source looks like be a single light source and required luminous intensity distribution of the light can be easily obtained.
SOLUTION: Plural Fresnel lenses for making light beams from the respective LEDs 28 into parallel beams are provided in front of the light source formed by plural LEDs 28, a diffusion lens 24 formed by plural diffusion lens element 24s is provided in front of the Fresnel lenses, and a condensing lens 26 is provided in front of the diffusion lens. The light beams from the respective LEDs are once made parallel beams, then diffused by the diffusion lens 24, and then once converged by the condensing lens 26 to be diffused and applied to the front of the light. The shapes of the respective diffusion lens elements 24s and the condensing lens 26 are suitably adjusted to easily set the maximum diffusion angle of the light in front of the light and the distribution of light intensity to aimed values. By the diffusion action of the diffusion lens 24, the whole of the light source can be made to emit light substantially uniformly over a wide area.
