Instrument Systems, a leading global manufacturer of LED Test & Measurement systems has recently developed its ISP 1000 Integrating Sphere which has been specially designed with a diameter of one meter for precise measurement of the total radiant power and luminous flux of lamps. It is particularly suitable for larger and more powerful LED modules with applications in solid-state lighting.

Test samples can be placed inside the integrating sphere on a height-adjustable sample stage or in a lamp post with suspended or upright configuration. These setups enable the total luminous flux to be determined in 4pi. Alternatively, the light radiation can also be launched from outside through a side port, allowing the heat dissipated from large high-power LED modules to be kept out of the sphere. This is why launching light from the side is ideal for testing light engines with applications in solid-state lighting if they have a forward radiation pattern.

Advanced design and low measurement uncertainty are integral to the ISP 1000. Its innovative design reduces the effect of compromising influences caused by baffles and ports to a minimum and thereby permits more accurate measuring results than previous designs.
