电性室的主要设备有LED光色电测试系统和LCR测试仪。
LED光色电测试系统由直流恒压/恒流电源、积分球、光谱分析仪组成，用于测量LED的相对光谱功率分布、相关波长、光通量、正向电压、反向电流等。LCR测试仪用于测量电阻、电容、电感及变压器的阻值、容值、感值及漏感等参数。

LED parameter test system is composed of DC constant voltage/current power supply, integrating sphere and optical spectrum analyzer. It measures relative spectrum distribution, wavelength, luminous flux, forward voltage, reverse current of LED. LCR tester is used to measure resistance, capacitance, inductance and leakage inductance of resistor, capacitor, inductor and transforme
