testing method:
; d6 y6 N3 |/ `/ F8 r/ e, B13.2 the lamp is switched on at ambinent temperature (definition as in IEC/TS 62504 and conditions as indicated by the manufacturer or the power is increased until 150%of the rated power is reached." a# f; F" I% l2 F) M
the test is continued until the lamp is thermally stabilised. a stable condition is reached, if the lamp cap temperature does not change by more than 1k in 1h the lamp shall withstand the extreme electrical conditions for at least 15min , after stabilization is reached.
% B# p; g# R% g/ }7 [a lamp which fails safe and has withstood the extreme electrical conditions for 15min ,has passed the test, provideed the compliance(see 4.1 and 13.6) is fulfilled.% S4 C' s, y: m3 Z1 q0 n
问题1:这个150%功率,是调节输入电压,知道功率达到150%,大家都是采用调压器调节的吗?
6 g" S- ?( v1 a问题2:是否还需要按照IEC62031-2008 13.2 overpower condition

是否还需要150%功率施加完毕,恢复到正常工作电压直到热稳定。机构是否还进行绝缘电阻试验?
