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.
Claims25
A test apparatus for use in testing a light sensor, comprising:
- a light source having a plurality of light emitting diodes (LEDs) with parallel connection for emitting a test light;
- a photo-mask having at least one diffuser interface, said light source disposed inside said photo-mask, said test light being guided to the outside of said photo-mask through said diffuser interface;
- and
- a sensor bearing area disposed at the outside of said photo-mask and being at an ambit to allow said test light to reach from said photo-mask so as to bear said light sensor;
- wherein said test light emitted by said light source is diffused by said diffuser interface to an allocation area of said light sensor for testing said light sensor.
A light source of testing a light sensor for use in a test apparatus for receiving working current of a power supply port to generate a test light required by said test apparatus testing said light sensor, said light source comprising:
- an adjustment unit controlled amperes of said working current to adjust brightness of said test light;
- and a plurality of LEDs, said plurality of LEDs being parallel connection, said plurality of LEDs received said working current through said adjustment unit in order to emit said test light;
- wherein said test apparatus further includes a photo-mask, a sensor bearing area, a closed shell and a processor.
A test method for use in testing a light sensor, comprising:
- bearing said light sensor through a sensor bearing area;
- emitting a test light through a light source, said light source having a plurality of LEDs with parallel connection, said light source disposed inside a photo-mask;
- emitting said test light to the outside of said photo-mask through at least one diffuser interface of said photo-mask;
- and
- testing said light sensor through said sensor bearing area disposing at the outside of said photo-mask and said sensor bearing area being at an ambit to allow said test light to reach from said photo-mask.
