The automotive optical engineer has an entirely new set of rules to follow for a "smooth lighted appearance" with the introduction of LEDs into the automotive signal lighting market. To move away from the "polka-dot" appearance long associated with the usage of LEDs as the light source for automotive lighting, and give the consumer a smooth lighted appearance to his lamp, there are several optical parameters that must be observed. The number and type of LEDs used, the size of the optical elements used, the spacing of the optical elements, plus many other factors all play a critical role and must be considered in the solution to the "smooth lighted appearance" in an automotive signal lamp. The "smooth lighted appearance" in an automotive signal lamp has long been a difficult problem to which there is more than one solution. The most visually pleasing and effective solution is not always the most easily obtainable solution since photometry requirements and smooth lighted appearance can be diametric goals. Subsequently the most cost effective and the easily "doable" solution may not give the ultimate in esthetically pleasing results for the consumer. Therefore, we outline the parameters that need to be considered to obtain a "smooth lighted appearance" for an automotive signal lamp, and to clarify the methods and "tools" that are required to meet this goal.
