Technical problem to be solved in the utility model provides a kind of LED collector lens, makes it improve the light source utilization rate when realizing effective optically focused.
For this reason, the utility model provides following technical scheme:
A kind of LED collector lens comprises: collector lens main body, described collector lens main body are round table-like and the bandy revolving body of bus, and have the optical axis that overlaps with the gyroaxis of revolving body; The light source holding tank is positioned at the small end face of described collector lens main body; Exiting surface is positioned at the large end face of described collector lens main body, and to described condenser main body sunken inside; Fully reflecting surface is positioned at described collector lens external side of main body face.
Further, described light source holding tank comprises: the holding tank main body is the round table-like and aduncate revolving body of bus; A cylindrical end face is connected on the small end face of described holding tank main body; Segment is positioned at described cylindrical other end.
Further, described exiting surface comprises: spherical crown, be positioned at described exiting surface middle part, and the outside outstanding spherical crown in summit; The ring-type curved surface is around the circumference of described spherical crown.
Further, a described cylindrical end face overlaps with the small end face of described holding tank main body; The cross section of described segment overlaps with described cylindrical other end.
Further, the summit of described spherical crown is positioned at the below of the large end face of described collector lens main body; The summit of described spherical crown and the summit of described segment all are positioned on the described optical axis.
Further, described LED collector lens also comprises: light source is packaged in the described light source holding tank.
The utility model utilizes total reflection and the refraction principle of light, not only realized light-focusing function efficiently, also greatly improved the utilization rate of led light source, in addition, the machine-shaping of the LED collector lens that the utility model provides is also simple relatively, it is very little that its size can be done, and is conducive to realize the miniaturization of advertisement projection lamp light source.
