However, when a single annular light source illuminates the lens, a ring-shaped bright line is formed on the lens, which causes a dead angle of observation and also becomes a blind spot for detection. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a light source device for detecting a curved lens which can improve detection accuracy. Another object of the present invention is to provide a detector for detecting a curved lens (four). Therefore, the light source device for detecting a curved lens of the present invention comprises: a lamp cover, a plurality of light sources, and a control system. The lampshade has a top side and a light exiting side, and the lampshade has a plurality of annular regions therein. The diameter of the annular regions is decreased from adjacent to the light emitting side to the top side. The light sources are disposed in the annular area towels. The control (4) Concentric (4) The light sources can be turned on at different times. The foregoing light source device can be combined with an image taking system to form a detector for detecting curved lenses 200937009. Thereby, by using the light sources of different annular regions, the detection of the mirror to be tested can be partitioned to avoid the detection blind spots formed by the existing single annular light source, and the detection accuracy can be improved. The above and other technical contents, features and effects of the present invention will be apparent from the following detailed description of the preferred embodiments. Referring to Figures 1 and 2, a preferred embodiment of the detector for detecting curved lenses of the present invention will be described. The detector 1 comprises: a light source device 2 and an image capturing system 3. The light source device 2 includes a lamp cover 21, a plurality of light sources 22, and a control system (not shown). As shown in FIG. 3, the lamp cover 21 has a three-layered tower shape, and the lamp cover 21 has a top side 211 and a light exiting side 212, and two annular receiving grooves 213 and 214 are formed on the inner side. 215. The annular accommodating groove 213 adjacent to the top side 211 has the smallest diameter, and the annular accommodating groove 215 adjacent to the light-emitting side 212 has the largest diameter. The diameter of the annular accommodating groove 214 located in the middle is between the two annular accommodating grooves 213 and 215. between. The light sources 22 are respectively disposed in the annular receiving grooves 213, 214, 215, and are distributed to form three annular regions (not labeled in the figure). In the embodiment, the light source 22 is a light-emitting diode lamp, but Other light sources can be used, not limited to this. Referring to FIG. 1, the light sources 22 disposed in the different annular receiving grooves 213, 214, and 215 have different inclination angles, so that they can have defects such as 6 ❹ 白 and white spots with respect to the light exiting side 212, and can analyze the defect area. size. In summary, the light source device for detecting a curved lens of the present invention can partially illuminate the lens to be tested, and can avoid the accuracy of detecting the blind spot of the conventional single-ring source, which can accurately achieve the present invention. Objective 200937009 has different positive light exit angles, and the closer to the light source 22 of the top U, the more perpendicular to the light exiting angle 212, and the light can be illuminated to the lens 4 to be tested.
