灯具耐久性试验室如何选择合适功率的加热装置

How to Select SuitableHeating Systemfor Lamp Endurance Test Chamber

耐久性试验是LED灯具安全合格评定的一个重要指标。GB7000.1-2007《灯具第1部分:一般要求与试验》标准12.3.1规定:"试验期间箱内环境温度应保持在(ta+10)℃±2℃…"。因此,必须对灯具耐久性试验室进行加热,而且加热装置功率必须与试验温度相匹配,否则会由于功率太小造成温度达不到试验要求或功率过大造成资源浪费。该文主要介绍了在灯具耐久性试验室改造过程中如何选择匹配的加热装置。

Endurance test is an important index of LED lamp safety qualification.Clause 12.3.1 of GB7000.12007 Luminaires-Part 1 ：General requirements and tests required：The ambient temperature within the enclosure shall be maintained within±2 ＇℃ of （ta ＋ 10） ℃ during the test....So must heating the Lamp endurance test chamber during test,and the heating system must be suitable for the temperature,or other the temperature not require to the standard because of the heating power too small or waste resources because of the heating power too large.The article introduced how to select the suitable heating system for Lamp endurance test chamber.
