摘要： Disclosed herein is a lighting apparatus (100) for a vehicle front headlight (900) and vehicle front headlight (900) equipped therewith. The lighting apparatus comprises at least one first projection light unit (700) for providing a low-beam function and a second projection light unit (500, 600) for providing a high-beam function, as well as a light shield (4) arranged in a central plane (40) extending between the first and second projection light units (700, 500, 600). Each projection light unit (700, 500, 600) has at least one LED (7, 5, 6) as the light source. The lighting apparatus (100) is provided with a common lens (1), for the first and second projection light units (700, 500, 600), positioned in front in the main irradiation direction. The light shield (4) extends outwards from the focal point (10) of the lens (1) disposed at the side thereof facing the projection light unit (700, 500, 600) in parallel to the optical axis (101) of the lens (1). The first projection light unit (700) is arranged at a side along the central plane (40). The LED (7) thereof reflects its light outwards from the central plane (40), upwards along the first axis (70). The first projection light unit (700) comprises a first optical element (800), said element orienting the light distributed by the LED (7) thereof towards the focal point (10) of the lens (1). The second projection light unit (500, 600) is arranged under the light shield (4). The LED (5, 6) thereof is oriented towards the focal point (10) of the lens (1) and it reflects its light over a second axis (50, 60) intersecting a focal point (10) of the lens (1). The second projection light unit (500, 600) comprises a second optical element (200, 300) which is designed as a collimation unit, said element aligning the light emitted by its LED (5, 6) in the focal point (10) direction of the lens (1). A light conducting element (2, 3) is present which is designed as a refractor or a light refracting body to serve as the second optical element (200, 300), the light coupling area (21, 31) of which faces towards the LED (5, 6) of the second projection light unit (500, 600) and the light output area (25, 35) of which is oriented to the focal point (10) of the lens (1). Each light emitted by an LED (5, 6) within the light conducting element (2, 3) is subject to one light deflection at most via total internal reflection (TIR). The light conducting element (2, 3) comprises a surface (20, 24, 30, 34) having a continuous, parabolic geometry

摘要： The invention provides a lighting module (1) for an automotive headlamp, the lighting module comprising a first-type primary optical element (2) projecting a primary low beam from a low beam light source (21), a second-type primary optical element (3), projecting a primary side beam from a side beam light source (31), a diaphragm element (4) and a main optical element (5). The main optical element (5) is suitable for receiving the primary side beam and projecting a side beam pattern, and suitable for receiving a part of the primary low beam which has not been reflected by the diaphragm element (4) and projecting a low beam pattern, wherein primary low beam rays corresponding to the front edge (41) are projected as a cut-off line of the low beam pattern. The first-type primary optical element (2), the second-type primary optical element (3), the diaphragm element (4) and the main optical element (5) are integral to each other, thereby forming the lighting module (1).

摘要： The present invention is provided with a semiconductor-type light source (2) and a reflector (3). The reflector (3) has reflection surfaces (31U) to (31D). The semiconductor-type light source (2) is disposed at or near a reference focal point F of the reflection surfaces (31 U to 31D). The reflection surfaces (31 U to 31D) are divided into upper and lower sides in a direction in which light is to be radiated from the semiconductor-type light source (2), with respect to an X axis passing through a center O of the semiconductor light source (2) or its proximity. Among the upper and lower reflection surfaces, on the upper side, convergent scattering reflection surfaces (31U to 34U) are disposed, and on the lower side, divergent scattering reflection surfaces (31D to 34D) are disposed. As a result, the present invention is capable of forming an approximately ideal light distribution pattern HPA for high beam.

摘要： This invention provides a cooling device (1) for cooling a light source comprised in an automotive lighting device. The cooling device (1) comprises a heat sink (2) and a flow guide (3). The heat sink (2) has a source point (21) intended to receive a light source, the source point (21) being in thermal contact with the rest of the heat sink (2), the heat sink (2) further comprising a heater (22) where heat from the heat sink (2) is communicated from the source point to ambient air, thus generating heated ambient air. The flow guide (3) comprises an input (31) and an output (32), in such a way that heated ambient air is intended to flow from the input (31) to the output (32), the input (31) being in fluid contact with the heated ambient air and the output (32) being in fluid contact with the source point (21) so that when the heated ambient air flows from the input (31) to the output (32), further heat may be evacuated from the source point (21).

摘要： A lens body includes a first lens portion and a second lens portion and is configured such that light from a light source exits through a first exit surface of the first lens portion after being partially blocked by a shade of the first lens portion, further exits through a second exit surface of the second lens portion, thereby forming a predetermined light distribution pattern by the shade, wherein the first exit surface is a surface for condensing the light from the light source that exits through the first exit surface with respect to a first direction and is configured as a semicircular cylinder surface, and the second exit surface is a surface for condensing the light from the light source that exits through the second exit surface with respect to a second direction orthogonal to the first direction and is also configured as a semicircular cylinder surface.
