A smooth, repeating rise and fall in light intensity over time.

A pulse lighting event is modeled as a sine wave because a sine function produces a smooth, continuous rise and fall over time, which matches how a pulse is intended to behave visually.

In this context, light intensity is mapped to the value of a sine wave as time progresses:

* The crest of the sine wave represents peak intensity.
* The trough represents minimum intensity.
* The zero crossings define the midpoint or base intensity.

As time advances, the sine wave oscillates, causing the light to gradually brighten, reach a maximum, then smoothly dim and repeat. This avoids abrupt transitions and hard edges, producing an organic, rhythmic motion often described as a “breathing” effect.

Because sine waves are mathematically smooth and periodic, they are ideal for pulse lighting events that need consistent timing, predictable behavior, and visually pleasing transitions without flicker.
