Abstract

The invention discloses a method and a device for accelerated detection of lumen maintenance of a lighting device. The method for accelerated detection of the lumen maintenance of the lighting device comprises the steps of determining a detection temperature, wherein the detection temperature is the environmental temperature at which the accelerated detection is conducted on the lighting device, and the detection temperature is higher than the normal temperature; adjusting the current environmental temperature to the detection temperature; and conducting accelerated detection on the lumen maintenance of the lighting device at the detection temperature. By the aid of the method and the device, the fact that the detection temperature is higher than the normal temperature is confirmed before the lumen maintenance of the lighting device is detected, so that the detection temperature guarantees that the detection period of the lighting device is shortened on the condition that a failure mechanism is not changed, and the life of the lighting device can be detected quickly.

Description

technical field [0001] The invention relates to the field of optoelectronics, in particular to an accelerated detection method and device for the lumen maintenance rate of an illumination device. Background technique [0002] The luminous flux maintenance rate is an important data about the service life of the lighting device, but the detection time of the luminous flux maintenance rate is long, so it is necessary to accelerate the detection of this data. This accelerated test method is used to calculate the service life of LED lighting products Time, that is, whether the luminous flux maintenance rate meets the requirements of the declared life (such as using lighting products for 25,000 or 30,000 hours, the luminous flux maintenance rate is above 70%). The accelerated test method for the luminous flux maintenance rate of traditional lamps and light sources is, at room temperature Light the lamps and light sources continuously for 6,000 hours. If the luminous flux maintenan...
