PURPOSE: A condenser lens for a light emitting diode is provided to condense light from the light emitting diode by improving the structure of the condenser lens. CONSTITUTION: A concave groove(25) is formed in the lower part of a condenser lens. The condenser lens comprises a concave spherical surface(21). The light from the light emitting diode(10) is projected on the spherical surface. A flat plane(24) is formed on the spherical surface. A convex lens part(23) is formed in the outer circumference(22) of the condenser lens. |
