A power drive system is adapted for a sliding door mounted on at least one side of a vehicle for sliding movement forwardly and rearwardly of the vehicle. A semiconductor die is attached to one side of a substrate having discrete conductive elements such as a ball grid array on the opposing side thereof. The LED chip has a side-surface portion, a top-surface portion, a bottom-surface portion, and a light-emitting layer sandwiched between the top-surface portion and the bottom-surface portion, and the fluorescent material in the translucent resin is provided in a layer form on a bottom surface of the package to entirely or partially cover the side-surface portion of the LED chip. The advantage of the concept presented allows the choice of a suitable filter pertaining to a particular traffic configuration, meaning a particular choice of individually filtered frequency bands set at different gain and intended to support a diversity of traffic formats.
