APRIL 9, 2009--The ISP 1000 integrating sphere has been designed with a 1-m diameter for precise measurement of the total radiant power and luminous flux of lamps. It is 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. The setups enable the total luminous flux to be determined in 4π. Light radiation can also be launched from outside through a side port, allowing the heat dissipated from LED modules to be kept out of the sphere (appropriate for testing light sources with a forward radiation pattern). The design reduces the effect of compromising influences caused by baffles and ports to a minimum to improve accuracy.

PRESS RELEASE

1 Meter Integrating Sphere

New integrating sphere for testing high-power LED modules and SSL light sources

The ISP 1000 Integrating Sphere from Instrument Systems is the latest development by the leading global manufacturer of LED Test & Measurement systems. The ISP 1000 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.
