Abstract:
Disclosed are a light distribution assembly (210) and an illuminating lamp. The light distribution assembly (210) comprises a light diffusion element (211), a first light reflection element (213), and a second light reflection element (212); the first light reflection element (213) and the second light reflection element (212) are arranged on two opposite sides of the light diffusion element (211) respectively, and a light distribution chamber, which is of a flaring structure, is formed among the first light reflection element (213), the light diffusion element (211), and the second light reflection element (212); the side of the light distribution chamber opposite the light diffusion element (211) is a flaring end (214); and the light diffusion element (211) is recessed at the side towards the flaring end (214) to form a light source cavity (2110), which is of a groove structure, and the light source cavity (2110) comprises a first diffusion portion (2111) facing a reflection face of the first light reflection element (213), a second diffusion portion (2112) facing the flaring end (214), and a third diffusion portion (2113) facing a reflection face of the second light reflection element (212).
