摘要： The invention relates to a masked beam motor vehicle headlamp of the type comprising, in succession: a reflector (1); a light source (3); a masking screen (E) having a cutoff edge (A); and a converging lens (4). The headlamp is characterized in that the screen is fitted, beneath its cutoff edge (A) and at least in its central portion, with an opening suitable for allowing a portion of the light flux directed towards the screen to pass therethrough. Means are provided to direct said light flux passing through said opening so that it is combined with the light flux which is not intercepted by the screen, thereby improving the light characteristics of the masked beam as finally projected by the headlamp.

摘要： The low-beam headlight has a reflector, in which a light source is mounted and a light-permeable disk which has optical elements. Light from the light source is reflected as a light beam by the reflector which would illuminate a region (62) of a measuring screen (60) placed in front of the headlight so that the region (62) has a horizontal light-dark boundary without being effected by or without action of the light-permeable disk. A first part of the light beam reflected by the reflector illuminates a first part (64a,64b) of the screen under boundary lines (65a,65b) inclined relative to the light-dark boundary (63). A second part of the light beam reflected by the reflector illuminates a second part (66) of the measuring screen between the light-dark boundary (63) and the boundary lines (65a,65b). A portion of the first part of the light beam is at least partially deflected by the optical elements of the light-permeable disk so that it produces the higher lying section of the light-dark boundary associated with the vehicle's own traffic side of the light beam from the low-beam headlight after passing through the disk.

摘要： A vehicular lamp having an improved external appearance, wherein a proximate part of a corner part of the reflective surface and a part (approximately the upper half) of the adjacent non-reflective surface are segmented in the diagonal direction in the prescribed width, and a plurality of small reflective surfaces are formed in a step-like manner in the diagonal direction in this segmental part. The front-view appearance of the lamp when the bulb is illuminated is improved thus through illumination of the reflector to the most exterior point at the corner part with the reflected light provided from the small reflective surfaces. The available solid angles on both sides of the segmental part are wider than in the case where the entire areas of the reflector are formed as a multiple reflection surface so as to eliminate every non-reflective surface at the corner part, and thus the influence on the light distributing performance is minimized.

摘要： A headlamp for an automobile vehicle comprises a luminous filament, a reflector, and a closing glass. According to the invention, the reflector comprises a parabolic base part and side pieces in the form of parabolic cylinders focussed on the filament, and in addition there are deflecting means, for example toroidal lenses, which re-direct the inclined rays of light received from the filament into the horizontal direction, towards the side pieces. A greater proportion of the luminous flux is thus recovered, which enables production of lamps with a small height and with a high efficiency.

摘要： An improved vehicle lamp for forward illumination, such as a headlamp or fog lamp is provided which is substantially devoid of upward directed glare light and which is formed with a synthetic organic polymer material. Heat shield means are disclosed for said vehicle lamp to prevent heat distortion otherwise occurring at the lamp roof by reason of its proximity to the light source used. Said heat shield means can be provided as an integral portion of the lamp roof when molded and further include heat transfer means to dissipate heat from the internal lamp envelope.

摘要： A vehicle lamp, such as a headlamp or fog lamp, having a concave reflector truncated at its top and bottom, one of the truncated surfaces being closer to the optical axis than the other truncated surface, and both truncated surfaces being substantially non-reflective. This achieves significant glare control without requiring a separate shield between the light source and the reflector.

摘要： The present invention relates to a headlight for automobile, with rectangular front opening, of the type comprising a reflector in the axis of which are disposed a light source for dipped-beam illumination cooperating with cut-off means, and a light source for far-beam illumination, a horizontal upper side and a horizontal lower side intersecting the reflector to delimit the rectangular opening of the headlight, wherein the upper side is substantially closer to the optical axis than the lower side, with the result that, for a total, unchanged height of the headlight, the zone of the mirror furnishing the dipped-beam illumination is reduced, this allowing an optimum compromise for far-beam and dipped-beam illumination.
