Optical lens assembly and illumination device comprising the same

An optical lens assembly, comprising:

• an optical component having a reflector, the reflector having a light emission portion and a light incidence portion, and an accommodating space is formed in the reflector and adjacent to the light incidence portion;
• and
• an outer lens having a light guiding column and an outer light emission portion connected to a top end of the guiding column, the outer lens being disposed at a side of the optical component, wherein the light guiding column corresponds to the accommodating space and is disposed in the accommodating space, and the outer light emission portion corresponds to the light emission portion and covers the light emission portion;
• wherein the outer light emission portion is disc-shaped, the light guiding column is a cylindrical column or a truncated cone, a bottom end of the light guiding column is concaved to form a light condensing groove, the light condensing groove has a side wall defined as a circular portion, and the circular portion has a total reflection surface configured to reflect light entering the circular portion to the outer light emission portion;
• wherein the outer lens and the optical component are configured to move toward or move away from each other, and the light guiding column is configured to move relative to the optical component in the accommodating space.

An illumination device, comprising:

• an inner lens having a reflector, the reflector having a light emission portion and a light incidence portion, and an accommodating space is formed in the reflector and adjacent to the light incidence portion;
• an outer lens having a light guiding column and an outer light emission portion connected to a top end of the guiding column, the outer lens being disposed at a side of the inner lens, wherein the light guiding column corresponds to the accommodating space and is disposed in the accommodating space, and the outer light emission portion corresponds to the light emission portion and covers the light emission portion;
• wherein the outer lens and the inner lens are configured to move toward or move away from each other, and the light guiding column is configured to move relative to the inner lens in the accommodating space;
• wherein the outer light emission portion is disc-shaped, the light guiding column is a cylindrical column or a truncated cone, a bottom end of the light guiding column is concaved to form a light condensing groove, the light condensing groove has a side wall defined as a circular portion, and the circular portion has a total reflection surface configured to reflect light entering the circular portion to the outer light emission portion;
• a light source disposed adjacent to the light incident portion;
• and
• a driving device configured to move the outer lens for changing a distance between the outer lens and the inner lens.
