LED brightness test tool

Abstract

The utility model discloses an LED brightness test tool, which comprises a bottom plate, a back plate and a lamp bead mounting plate, the bottom plate is horizontally arranged, and a groove for placing the illuminometer is formed in the bottom plate; the back plate is vertically arranged on the bottom plate and located on the rear side of the groove. The lamp bead mounting plate is detachably connected with the back plate; and the lamp bead mounting plate is used for mounting lamp beads. According to the utility model, the light-emitting center of the lamp bead can be ensured to be aligned with the center of the illuminometer, so that the data measured each time can be ensured to be the maximum brightness value of the lamp bead, and the true brightness value of the lamp bead can be measured conveniently. Different lamp beads are replaced to ensure that the centers of the lamp beads can still be aligned with the center of the illuminometer, so that the same lamp bead can be ensured to obtain good repeatability after multiple times of sampling, the consistency of data acquisition of a plurality of lamp beads can also be ensured, and the brightness range of the lamp beads can be easily determined. In addition, brightness values of the same lamp bead at different heights can be easily obtained.
