Abstract
An LED lighting device includes a seat, an optical assembly and a light source, according to one embodiment of the present invention. 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 of the LED arrays 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 of the second optical members includes a set of optical walls. The set of optical walls surrounds one of the first optical members. On a cross-section of any of the first optical members in a width direction, the optical wall and an optical axis of the LED chip form an acute angle A, and the acute angle A is between about 30 degrees to about 60 degrees.
