testing method:
$ I, Q/ A2 g7 D8 U' P- 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.$ V9 V2 j0 V7 y
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$ c4 ]5 }7 z* C# b* N. ua 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.( s* Z0 _! Y, V; a n, A
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?* o* c1 O1 O) d6 ]& E V8 [' v
问题2:是否还需要按照IEC62031-2008 13.2 overpower condition
/ U3 A/ Q1 D; T- N2 T5 i4 v% y5 vafter finalising the overpower mode ,the module is operated under normal conditons until theermally being stable .; C) O6 @# b: h' @; Y5 Y0 v: ^: d# }
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?2 N1 M9 `( _. E* m. H! c, m
