摘要： A projector headlight for a low beam can include a light source, an ellipsoidal reflector, a projector lens and a shade. Light emitted from the light source can form a fundamental light distribution pattern from the projector lens via the ellipsoidal reflector by shielding an upward portion of the light with the shade. The shade can form a blurred part on a horizontal cut-off line using a radiused R surface between a top and front edge lines of the shade. Therefore, a contrasting difference between the upper and lower sides of the horizontal cut-off line can be reduced so as to be able to conform to a light distribution standard for a headlight. The R surface can be configured with a reflex surface or a non-reflex surface to match the light source. Thus, the projector headlight can perform a favorable light distribution pattern utilizing a simple structure.

摘要： A lighting fixture for a vehicle where a fit part of a waterproof cover and the mounting part of a reflector are covered with a removal preventing piece in the waterproof construction of the reflector so mounted as to be tilt freely in the lamp housing. The removal preventing piece is provided around the peripheral part of a socket cover for a lamp socket of the used lamp and the number of parts is all the smaller or the use of the flange part on the lamp socket as a removal preventing piece makes it possible to provide a simpler and smaller lighting fixture for a vehicle.
