Embodiment Construction

[0012] See figure 1 and figure 2 , a light source measurement method provided in the first embodiment of the present invention. The light source measurement method is used to measure the size of the light spot irradiated by a light source 9 in a certain optical path. In this embodiment, the light source measurement method is used to measure an infrared light emitting diode. Described light source measuring method comprises the following steps:

[0013] In the first step, a drawing board 10 is provided, and at least one measurement pattern 11 is pre-drawn on the drawing board 10 . One or more measurement patterns 11 may be pre-drawn on the drawing board 10 . When multiple light sources 9 need to be tested in batches and quickly, multiple measurement patterns 11 can be drawn on the drawing board 10 to complete simultaneous testing of multiple light sources 9 . In this embodiment, the drawing board 10 is pre-drawn with a measurement pattern 11 . The measurement pattern 11 ...

Abstract

The invention relates to a light source measuring method which is used for measuring at least one light source. The light source measuring method comprises the following steps of: providing a drawing board, wherein at least one measuring pattern is predrawn on the drawing board, the measuring pattern comprises a central point and a plurality of lines, and the plurality of lines are distributed from the central point to the periphery; correspondingly irradiating one measuring pattern on the drawing board by using a light source; shooting the measuring pattern irradiated by the light source by utilizing a shooting device which can sense lights emitted from the light source; and in the shot images, acquiring the range of the light source irradiation area according to the occupied area and the corresponding lines when the lights irradiate in the measuring pattern. The light source measuring method provided by the invention does not need expensive devices and complex operations and can simply and rapidly acquire the size and the divergence angle of the light source irradiation area just by referencing the measuring pattern.

Description

technical field [0001] The invention relates to optical measurement, in particular to a light source measurement method. Background technique [0002] Light-emitting diode (LED) is a solid-state light-emitting device that converts electrical energy into light energy. It is widely used in indication, display, decoration, lighting and many other fields. [0003] However, when an LED is installed in a display device or a lighting device, it is often not necessary to obtain all the parameters of the LED. It is only necessary to measure the size of the divergence angle and the size of the light spot irradiated in a certain optical path. However, such a simple parameter measurement often requires the use of spectrometers, integrating spheres and other expensive equipment and complex measurement processes. This kind of measurement is difficult to adapt to the needs of low-cost, fast and convenient measurement in the industrial measurement process. Contents of the invention [...
