<p>PURPOSE: To satisfy the light distribution standard even by the tilt angle or even if the transmittance of a covering member is changed by the angle of incidence. CONSTITUTION: In respective lens cuts 6 to be applied to a lens 5, the quantity of light in relation to the dispersing direction is controlled so that the transmission factor depending on the angle of incidence when the light to be dispersed by the lens cuts 6 is transmitted to a rear window glass 30 as a covering member may be corrected. The large quantities of light are arranged to a part in which the transmittance are largely decreased, and the small quantities of light is arranged to a part in which the transmission factor is not largely decreased, and the illuminance after the transmission to the rear window glass 30 is matched to the light distribution standard.</p> |
