摘要： A light shielding plate for shielding part of light from a light emitting element to a projection lens is arranged between the light emitting element and the projection lens, and an opening penetrating the light shielding plate is formed in a required region of the light shielding plate. With this configuration, the drawing light distribution pattern can be formed as a light distribution pattern corresponding to the opening shape of the opening. In this configuration, the inner peripheral surface of the opening has such a surface shape that light emitted from the light emitting center of the light emitting element does not enter the projection lens. Thus, even if the plate thickness of the light shielding plate is increased, occurrence of color unevenness in an outline portion of the drawing light distribution pattern due to light reflection on the inner peripheral surface of the opening is effectively reduced.

摘要： Disclosed are a headlamp light-sensing detection device and a headlamp. The headlamp light-sensing detection device includes a condensing lens, a lens hood and a light-sensing element. The condensing lens is arranged in front of the light-sensing element, to converge external light to the light-sensing element. The lens hood is arranged between the light-sensing element and the condensing lens, and may be configured to shield the light which is projected to the light-sensing element by a high beam light source and a low beam light source, so as to reduce optical crosstalk, such that external ambient light is received accurately, thereby achieving a desirable light-sensing detection effect. The light-sensing element may provide photoelectric parameters according to the brightness of sensed light, and then an MCU chip collects the photoelectric parameters and provides a corresponding control signal.

摘要： A vehicle lamp is configured in such a manner as to project light from light-emitting elements (22 and 42) of a first and a second lamp unit (20 and 40) forward through lenses (30 and 50) in the lamp and accordingly form a low-beam light distribution pattern having a Z-shaped cut-off line. In addition, a part of a plurality of lens elements formed on a front surface (30a, 50a) of each of the lenses (30 and 50) is formed as a specific lens element (30aA3, 50sB3) having a freeform surface shape. It is configured in such a manner as to form an inclined portion of the Z-shaped cut-off line with light emitted from the specific lens elements (30sA3 and 50sB3). Consequently, the degree of flexibility in forming the Z-shaped cut-off line is increased.

摘要： Vehicle headlights are equipped with a right-side lamp, a left-side lamp, and a control unit. A right-side light distribution pattern and a left-side light distribution pattern include an overlapping area and a non-overlapping area. In a case where the steering angle is greater than the prescribed angle, the control unit controls power supplied to light-emitting parts of the right-side lamp and power supplied to light-emitting parts of the left-side lamp such that: a first area of a first light distribution pattern is located in the non-overlapping area; a second area of a second light distribution pattern is located in the overlapping area; and a first intensity of the light in the first area becomes greater than the sum of a second intensity of the light in the second area and a third intensity of the light in the area overlapping the second area within the first light distribution pattern.

摘要： An appearance light module for motor vehicle headlamp comprises at least one light source and one secondary optical element. The secondary optical element has an intake geometry with an entry surface for the light generated by the at least one light source, and an emission geometry with an exit surface for the light passing through the entry surface of the intake geometry. The exit surface of the emission geometry can be seen from outside the motor vehicle when the headlamp is installed in the motor vehicle. The appearance light module is not suitable for generating a low beam light distribution or a high beam light distribution. The appearance light module has no primary optical element, and the light from the at least one light source reaches the entry surface of the secondary optical element without being reflected and without passing through a refractive or diffractive optical element.

摘要： A heat sink for an electronic component and its manufacturing method by applying a nanopulsed laser. The heat sink includes a body provided with an outer layer, including a surface layer having a radiative exposed surface and a layer immediately underlying the surface layer. The underlying layer is made of a material based on a metal and the surface layer is made of an oxide of said material. The outer layer includes juxtaposed nodules. The heat sink originally combines a surface chemical state promoting heat emission and a structure geometrically promoting heat exchange, in order to synergistically improve its heat dissipation capability.
