COMPOUND LENS AND LED LIGHT SOURCE DEVICE INCORPORATING THE SAME |
| 摘要 |
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. |
