Which is better, multi-stage diffusion or micro-light?

Miniature light guide is better than multi-stage diffusion. The light source used in multi-stage diffusion is soft and comfortable, which is integrated with the uniform diffusion of annular light source. The patented technology of micro light guide structure (utility model patent: ZL2020200937 14.2) makes the irradiated light softer and more uniform, which can better protect the eyes.
