Advanced LED technology for automotive applications
Since the introduction of high-power LEDs, there has been considerable innovation in the automotive lighting industry. For example, low-beam headlights have historically been achieved with the use of a single lamp as the light source, and with a set of optics—that imaged the light onto the road—to create the cut-off pattern. With the first generation of LEDs, the lamp light sources were replaced, but similar optics were still used. Some of the recent major advances in LED technology include a reduction in the source size, as well as improvements to the luminance and tolerance (the capacity for precise alignment of the optics components, with regard to the light source).
