Problems solved by technology

However, this method of controlling the light emitted by the lamp leads to inefficiencies in the headlight assembly, especially for the low beam function, since they prevent the headlight assembly from using the light emitted by the lamp, for example through absorption by raised shuttles A large percentage of light in

Embodiment Construction

[0015] Embodiments of the present invention will be described more fully hereinafter with reference to the accompanying drawings. However, this invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth below.

[0016] figure 1 is a cross-sectional side view of a vehicle headlight assembly 100 according to the prior art.

[0017] Such as figure 1 As shown, lamp 10 is mounted within cavity 12 of reflector 14 . The cavity 12 is closed by a transparent lens 16 which may have a light directing element. Reflector 14 has a shaped light directing interior surface 18, which is generally polyellipsoidal in shape, but may be parabolic, or may have other shapes. The reflector 14 is configured to, in combination with or without a lens 16, shape the light emitted by the light source of the lamp 10 into high and low beams. The polyellipsoid reflective surface 18 has a central axis 20 and a focal point 22 . The reflector 14 may...

Abstract

The present invention provides a lamp (310) for a horizontal operating position within a vehicle headlight assembly (200). The lamp (310), as seen with respect to the vehicle, comprises a LED light source (311) for emitting light mainly to one side, and a reflective member (312) for shielding front and lower parts (L1, L2) of the light emitted by the LED light source (311) and reflecting them to desired directions. The present invention also provides a vehicle headlight assembly (200) comprising such a lamp (310), and, further, a reflector (14) for shaping the light emitted by the LED light source (311) into a beam, and a shuttle (26), adjustable between positions to shape the beam into a high beam or a low beam.

Description

technical field [0001] The invention relates to a headlight assembly and a corresponding lamp for a vehicle, or in particular the invention relates to a vehicle headlight assembly and a corresponding lamp and reflector design. Background technique [0002] A typical vehicle headlight assembly includes a reflector and a lamp positioned with its light source at or near the reflector's focal point. Currently, the majority of such lamps are of the halogen type, while some high-end cars use high-intensity discharge (HID) lamps, and in recent years, not only HID lamps, but also light-emitting diode (LED) retrofit bulbs have been introduced into this assembly. The reflector generally comprises a polyellipsoidal rear portion and a flat wall section between the rear portion and the front of the assembly. The front is usually covered with a clear lens. Typically, lenses, reflectors, or a combination of both are designed to direct light from a light source into a specified pattern. ...
