    摘要： An illuminating device includes a light source module for emitting light and an optical lens for adjusting the light. The light source module includes a reflecting unit and LEDs. The reflecting unit includes strip-shaped grooves each extending along a first direction. The LEDs are mounted on the reflecting unit in the grooves. The optical lens includes an array of lens units each including a main body, a light diverging portion and a light converging portion. The light diverging portion is for expanding a light field of the LEDs along the first direction. The light converging portion is for compressing the light field along a second direction. The reflecting unit is for further compressing the light field along the second direction.

    摘要： An optical lens (10) includes an array of lens units (11). Each lens unit includes a main body (101), a light diverging portion (112) and a light converging portion (114). The main body includes a light incident surface (110) and a light emitting surface (112) opposite to the light incident surface. The light diverging portion is used to expand a light field along an x-direction. The light converging portion is used to compress a light field along a y-direction. In specific embodiments, the light diverging portion and the light converging portion are respectively formed on the light incident surface and the light emitting surface.
