Title: METHOD, DEVICE AND SYSTEM FOR DETECTING LUMINANCE DEGRADATION OF LIGHT BAR
Abstract:
Provided is a method for detecting luminance degradation of a light bar. The method comprises: obtaining, on the basis of a luminance level of a light bar (270) measured by a light probe (310), a first luminance value of the light bar (270); performing a preset aging test on the light bar (270); obtaining, on the basis of a luminance level of the light bar (270) having undergone the aging test and measured by the light probe (310), a second luminance value of the light bar (270); and performing, according to the first luminance value and the second luminance value, calculation to obtain light degradation of the light bar (270). Also provided are a device and system (100) for detecting luminance degradation of a light bar. The invention enables detection of light degradation of a light bar to be performed at low costs, and can be operated conveniently.
