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

[0015] For a better understanding of the present invention, as well as other objects, advantages and capabilities thereof, reference is made to the following disclosure and appended claims in conjunction with the above-mentioned accompanying drawings.

[0016] Referring now more specifically to the accompanying drawings, in figure 1 A headlight 10 is shown in , which includes a first light source 12 with a bulb 12 a 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 a substantially white light. A second light source 16 is arranged around the bulb 12a and emits light in a different direction than the first light source, eg along axis 16a.

[0017] The first light source 12 and bulb 12a are part of a headlight assembly 20 which is operatively located within the reflector 18 and which also includes a lamp head 22 having a holde...

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 or an arc discharge source. 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 via an optic 42 for providing a daylight running light. Via the optic 42 light is emitted in a forward direction as well as toward the reflector to increase the lighting area.

Description

technical field [0001] The present invention relates generally to light sources and in particular to headlights. More particularly, it concerns headlights using different light emitters in order to achieve functional lighting and special aesthetic effects. Background technique [0002] It has been proposed to use solid-state light sources such as light emitting diodes as lighting units for vehicle lamps. 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. Therefore, it would be a development of the technology to take advantage of the aesthetics of LEDs combined with the greater lighting capabilities of many conventional light sources. Contents of the invention [0003] It is therefore an object of the invention to avoid the disadvantages of the...
