Bright, sunny, and illuminated all relate to light, but differ. Bright is the general word for light, color, or weather. Sunny means full of sunshine, for weather or a place. Illuminated is formal, meaning lit up by a light source. Other senses are not compared.

这三个词都可表示“有光”，但侧重不同：bright 是最通用的说法，可以形容光源、颜色或天气本身很亮；sunny 专指阳光普照的天气或时段；illuminated 则强调某物被（通常是人工的）光源从外部照亮，常用被动结构，语气较正式。这里不比较 bright 表示“聪明的”、sunny 表示“性格开朗的”以及 illuminated 表示“用彩饰装饰的”等其他义项。
