the sun is luminous and gives off its own light.
the sun is luminous and reflects light.

Explanation:

A luminous object emits its own light. The sun generates light through nuclear fusion in its core. Objects that are illuminated (like the moon) reflect light from a luminous source. Since the sun makes its own light, it is luminous and gives off its own light.
