Problems solved by technology

These light sources are superior to many conventional light sources due to their small size and long life; however, the amount of light available from any single unit is small, so many units are required to provide an adequate source of illumination, with consequent cost increase

Embodiment Construction

[0012] In order to better understand the present invention and its other objectives, advantages and capabilities, refer to the following disclosure and appended claims in conjunction with the above-mentioned drawings.

[0013] Now referring more specifically to the attached drawings, in figure 1 A headlight 10 of a vehicle is shown in, which includes a first light source 12 with a bulb 12a to illuminate the area in front of the light source 12. The first light source 12 is preferably a tungsten halogen bulb with a filament. The bulb 12a is arranged along the longitudinal axis 14 and emits substantially white light. The second light source 16 is arranged around the bulb 12a, and the second light source 16 emits light in a direction different from the first light source, for example, along the axis 16a.

[0014] The first light source 12 and the bulb 12a are part of a headlight assembly 20 that is operatively located within the reflector 18 and also includes a lamp cap 22 having a ...

Abstract

A vehicle headlamp ( 10 ) has a first light source ( 12 ) for illuminating an area forward of the light source ( 12 ). The first light source ( 12 ) is preferably a filamented tungsten halogen capsule. The first light source ( 12 ) is arrayed along a longitudinal axis ( 14 ) and emits substantially white light. A second light source ( 16 ) in the form of a plurality of light emitting diodes is arrayed about the first light source ( 12 ), and the second light source ( 16 ) emits light in directions substantially normal to the longitudinal axis ( 14 ), for example, along an axis ( 16 a) for providing essentially aesthetic illumination. The aesthetic illumination can be used with or without the first light source being illuminated.

Description

Technical field [0001] The present invention relates generally to light sources, and particularly to vehicle headlights. More specifically, it involves headlights using different light emitters in order to achieve functional lighting and special aesthetic effects. Background technique [0002] It has been proposed to use a solid-state light source such as a light emitting diode as a lighting unit of a vehicle lamp. These light sources are superior to many traditional light sources due to their small size and long life; however, the amount of usable light emitted from any single unit is small, so many units are needed to provide sufficient illumination sources, and the cost is consequently Increase. Therefore, the use of the aesthetic effect of light-emitting diodes and the strong illuminating ability of many traditional light sources will be a development of this technology. Summary of the invention [0003] Therefore, an object of the present invention is to avoid the disadvant...
