Abstract
An illuminating device includes a light source module for emitting light and an optical lens configured for adjusting the light emitted from the light source module. The optical lens includes an array of lens units. Each lens unit includes a main body, a light diverging portion and a light converging portion. The main body includes a light incident surface and a light emitting surface opposite to the light incident surface. The light diverging portion is configured for expanding a light field along a first direction, and the light converging portion is configured for compressing a light field along a second direction. The light diverging portion and the light converging portion are formed on at least one of the light incident surface and the light emitting surface. The light diverging portion includes parallel protrusions distributed along the first direction.
