The invention discloses a test device for near-field optical distribution of an LED lamp. The test device comprises a base; one side of the base is welded with a support frame; and one side of the support frame is provided with a first bearing; a rotating shaft is plugged into the first bearing; a swing arm is welded to the end portion of the rotating shaft; grooves are formed in the upper and lower ends of the swing arm respectively; and compression springs are installed in the grooves. According to the invention, the test device includes the swing arm, an imaging brightness meter, a spectrometer, a sample base and a platform base. The imaging brightness meter is composed of a two-dimensional CCD array with an optical lens; the swing arm rotates to drive the image brightness meter and thespectrometer to rotate around a to-be-tested LED lamp in a range of -130 degrees to 145 degrees; and optical distribution of the light fixture is simulated and designed. Compared with the traditionaldistributed photometer, the testing method has the following advantages: the LED light source is regarded as a complex surface light source rather than a point source, so that the measurement resultsare more accurate; and the test device is suitable for optical distribution test of the small power LED lamp.
Description
technical field [0001] The invention belongs to the technical field of light source measurement, and in particular relates to a testing device suitable for near-field optical distribution of LED lamps and a method for using the same. Background technique [0002] LED lamps are favored by the lighting source market due to their advantages such as high luminous efficiency, low power consumption, long life, low operating temperature, safety and reliability, and environmental protection. More and more LED lamps are used in large quantities for indoor and outdoor lighting, which has become a green technological light revolution in human history. Optical distribution characterizes the distribution of light emitted by a lamp in space, and is an important indicator for evaluating the performance and use effect of lamps. According to the optical distribution of LED lamps, the distribution of illuminance in the performance area, the efficiency and quality of LED lamps, etc. can also ...
