Illuminating device incorporating optical lens
First Claim
1. An illuminating device comprising:
- a light source module for emitting light, the light source module comprising a reflecting unit and a plurality of light emitting diodes (LEDs) mounted on the reflecting unit, the reflecting unit comprising a plurality of strip-shaped grooves each extending along a first direction, the LEDs being mounted on the reflecting unit in the grooves; and
an optical lens configured for adjusting the light emitted from the light source module, the optical lens comprising an array of lens units, each lens unit comprising a main body, a light diverging portion and a light converging portion, the main body comprising a light incident surface and a light emitting surface opposite to the light incident surface, the light diverging portion being configured for expanding a light field along the first direction, the light converging portion being configured for compressing a light field along a second direction, the light diverging portion and the light converging portion being formed on at least one of the light incident surface and the light emitting surface.

Abstract
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.
