During the test, the lamp shall not have any failure, burnt, otherwise it is unqualified.
9.6.2 Light failure and life measurement method of projection
To replace the luminous flux method with the illuminance method, in the distance from the height of the lamps and lanterns at 2 meters below the measurement center and along the road direction of the axis of the horizontal illuminance value of a point every one meter away, *** measurement of the five points, and the points of initial value of the comparison and derive the five points of the average value of the maintenance rate. Between 2000-5000h, every 336h interval measurement of the average maintenance rate value; such as 5000h when the lamps still meet the requirements, the illuminance value of each point in 2000h for the initial illuminance value, has been measured every 336h interval of the illuminance value of the corresponding initial illuminance value with the 2000h to compare and derive the average maintenance rate, by the above 10-point From the above 10 points of the average maintenance rate fitting curve deduced the average maintenance rate of 75% of the life time plus 5000h that is the life of the lamp. Select one of the street lamps and measure the luminous flux from 0 to 2000h by luminous distribution test method, and calculate the luminous flux maintenance rate of 2000h as the calibration value. Measurement of illuminance, the ambient temperature should be controlled at 25 ℃ ± 1 ℃ stable for more than 3h.
