澳洲ic等级独立式led驱动测试方法变更

test method revised for ic type led driver in australia/newzealand

led驱动的澳洲标准as/nzs61347.1:2016+a1:2018在2020年11月26日出版一项技术裁决，是关于宣称为ic等级的独立式led驱动的测试环境温度的澄清。

one ruling for standard as/nzs 61347.1:2016+a1:2018 had publishedat november 26, 2020, applicable for ambient temperature in thermaltesting of ic type independent led driver.

za1general

for thepurposes of this appendix, the re of clause 12of as/nzs 60598.1 apply.

as/nzs 60598.1:2017

the ambienttemperature within the draught-proof enclosure shall be within therange of 10 °c to 30 °c and should preferably be 25 °c. itshall not vary by more than ±1 °c during measurements andduring a preceding period long enough to affect theresults.

if, however,a lamp has temperature-sensitive electrical characteristics (e.g. afluorescent lamp), or if the ta rating of the luminaireexceeds 30 °c, the ambient temperature withinthe draught-proof enclosure shall be within 5 °c of the tarating and should preferably be the same as the tarating.

独立式led驱动需要按照灯具做热试验，当驱动（独立式驱动视为灯具）有宣称ta时，热试验在ta下进行。

new testmethod

无视独立式led驱动宣称的ta值，热试验在25℃下进行。

此次测试方法的澄清/修订，将使得独立式驱动更容易在覆盖隔热棉的情况下通过热试验。

this ruling for standard would make the thermal testing passmore easier while the independent led driver covered by thermalinsulation.

强烈建议广大制造商为自己的独立式led驱动(尤其家用的)宣称ic等级，并申请/升级澳洲安全报告和证书！

we strongly advise manufacturers of led driver (especially thosefor household use) to declare their product as ic-type, andapply/update their test report and certification as soon aspossible.
