Abstract
An LED lighting device includes a seat, an optical assembly and a light source. The seat has a baseplate and a sidewall. A chamber is formed between the baseplate and the sidewall. The optical assembly completely covers a light-emitting side of the LED lighting device. The light source is disposed in the chamber of the seat and includes multiple LED arrays. Each LED array includes an LED chip. The optical assembly includes an optical unit. The optical unit includes multiple first optical members and multiple second optical members corresponding to the first optical members. The LED arrays correspond to the first optical members. Each first optical member possesses an effect of light diffusion resulting from its own material property. Each second optical member includes one or more sets of optical walls. Each set of optical walls surrounds one of the first optical members.
