While 'ray' often refers to light, Japanese uses different words depending on context. 光 (ひかり) is general 'light', while 光線 (こうせん) specifically means 'ray/beam'. Using 光 alone may not convey the narrow beam nuance.
日差し (ひざし) emphasizes the rays or warmth of the sun, often used for sunlight streaming in. 日光 (にっこう) is more general 'sunlight'. For 'a ray of sun', 日差し is more natural.
