AI Technical Summary

⚠Technical Problem

Existing vehicle lighting fixtures for work vehicles, such as tractors, face challenges in illuminating the immediate vicinity while maintaining design aesthetics, as positioning side lights higher leads to dirt accumulation and design constraints.

⚗Method used

A vehicle lighting fixture with a horizontally oriented illumination lens and a light source positioned above the lens at a displacement angle, emitting light at a required inclination to ensure optimal illumination and uniform brightness, using a plano-convex lens with an aspherical surface to manage light distribution.

🎯Benefits of technology

The solution allows for effective illumination of the immediate area around the vehicle with uniform brightness, enhancing design freedom and reducing dirt accumulation, while maintaining a unified and aesthetically appealing appearance.

Abstract

The present invention provides a vehicle lighting fixture that, even when installed on the upper part of the vehicle body, effectively illuminates the area immediately in front of the vehicle, while also increasing the design freedom of the lighting fixture and the vehicle, thereby enhancing its aesthetic appeal. [Solution] The lamp unit 4 is equipped on a vehicle to illuminate the road surface immediately in front of the vehicle, and includes a light source (LED) 44 and an illumination lens 45 that projects the light emitted from the light source 44 to provide illumination in a required light distribution pattern. The illumination lens 44 has its lens optical axis Lx oriented horizontally, and the light source 44 is positioned above the lens optical axis Lx with respect to the illumination lens 45 at a required displacement angle. In addition, the light-emitting surface of the light source 44 is tilted forward at a required inclination angle with respect to the lens optical axis Lx and directed toward the illumination lens 44.
