Standard operating procedures of Spectroradiometer & Integrating Sphere System

Spectroradiometer & Integrating Sphere System as main test device to measuring LED lamps, it’s as a most important device to judge the quality of lighting products. How to operating these device and make it have better work condition became the point, so the standard operating procedures of device is necessary. In the practice, the standard operating procedures have two parts: one is standard laboratory hardware requirement; the second is operator’s skills and practices experience.

The following is details introduction of integrating sphere setup:

The first part laboratory hardware environment, normally, there have some requirements about photometric lab: Lab room size, this will be depend on by test device’s dimension and height of test device; the second is inside air flow at lab room, temperature range, humidity range and safety protection measures. These are general requirements, the details specs and requirement can refer relevant ISO and IEC etc standards.

The second part is point. First we need know what’s kind of device of spectroradiometer & integrating sphere system have: a one full test system consist of spectroradiometer, optical fiber, digital power meter(measuring electrical parameters), AC power source(power supply the tested lamp), DC power source(power supply the standard lamp), integrating sphere(provide the test environment), standard lamp(calibrate the integrating sphere) and cabinet(load all device together).

Standard operating procedures of Spectroradiometer & Integrating Sphere System

LPCE-2 (LMS-9000) High Precision Spectroradiometer Integrating Sphere Test System

Here is the SOP:

1、 Install the system. Check all connections to make sure all the connecting is correct(the connection included between the device and device and between device and power supply).
2、 Install the software and drivers. Turn on the computer and open software, then set up relevant parameters.
3、 Install the standard lamp at right place of integrating sphere, calibrate the system according to our user manual or operation video. We have several different systems that the calibration steps may be a little different.
4、 Install the tested lamp(attention the type of lamp, if the tested lamp is emitting light in all directions, like the LED bulb, CFL etc which had better install it at centre position of integrating sphere to do 4π test; if tested lamp is emitting light in forward direction, like the LED street lamp, LED panel etc which had better install in at side position of integrating sphere to do 2π test. After installed the tested lamp, turn on the AC power source and set pre-hear time at software. And run the test.
6、 If you test big luminaires in the integrating sphere, you need to use assistant lamp to correct the luminaire absorbtion problem. You can also refer to our user manual and operation video to do this.

NOTE: 1. Need to order the right size sphere according to your samples.
2. If you use the sphere system frequently, you need to calibrate the system using the standard lamp every week.
