ABSTRACT:
A light source of testing a sensor, a test apparatus and a method are disclosed. The test apparatus includes a light source, a photo-mask and a sensor bearing area. The light source includes a plurality of light emitting diodes with parallel connection for emitting a test light. The light source is disposed in a photo-mask. The photo-mask has a diffuser interface. The test light is then diffused to the outside of the photo-mask through the diffuser interface. The sensor bearing area is for bearing the sensor. The sensor bearing area is disposed at the outside of the photo-mask and locates at a position to enable the test light to reach. Therefore, the test light emitted by the light source is used to test the sensor.
