20150036347 | COMPOUND LENS AND LED LIGHT SOURCE DEVICE INCORPORATING THE SAME - A compound lens includes a first lens and a second lens coupled to the first lens. The first lens has a light incident face and a light exit face opposite to the light incident face thereof. The first lens defines a recess at a center of the light exit face thereof. The second lens has a refractive index lower than that of the first lens. The second lens is received in the recess of the first lens and a light incident face of the second lens directly contacts the light exit face of the first lens. A light emitting diode light source device incorporating the compound lens is also provided. | 02-05-2015 |
20150036356 | OPTICAL LENS AND LIGHT SOURCE MODULE HAVING THE SAME - A light source module includes a light source and an optical lens facing the light source. The optical lens includes a light incident surface facing the light source, and a light emitting face opposite to the light incident face. The light emitted from the light source is entered into the optical lens from the light incident face, and exited from the light emitting face. A refractive index of the optical lens gradually decreases along a direction from the light incident face to the light emitting face of the optical lens. | 02-05-2015 |
