Title:
SIGNAL LIGHTING FIXTURE FOR VEHICLE
Document Type and Number:
Japanese Patent JPH09259610
Kind Code:
A
Abstract:

To provide a signal lighting fixture for vehicle in such a manner that a specific light intensity distribution is easily realized and its good appearance is not degraded.

An inner lens 4 is divided into several blocks 4A,..., 4K. A Fresnel cut 4a (A,..., K) is formed in a vehicle signal lighting fixture 1 to offset a center C (A,..., K) in a preferable direction for realizing a specific light intensity distribution by directing a convergent light toward the respective blocks 4A,..., 4K. When a light passes through the inner lens 4, the light is controlled to travel in an appropriate direction for realizing the specific light intensity distribution in advance to ensure than an outer lens 5 certainly realizes the specific light intensity distribution.
