How about streaks of sunlight? Google Books
streak: a narrow band of light M-W
Alternately, you might want to consider streams and flickers [of sunlight]. Google Books
stream: a ray of light M-W
flicker: a wavering light M-W
bars, bands, and strips are also possible options. Ngram

It is regularly used in the gaming industry to refer to the capability of a graphical engine to render volumetric lighting, by means of which light is seemingly scattered when travelling through non-solid objects (like air).
