What is the Integrating Sphere?<\/a><\/strong><\/h2>\n

Integrating sphere is widely applied in testing lumen, chromaticity coordinates, CCT, dominant wavelength and peak wavelength etc for light source or luminaries. The IS-*M is the tradiontal Integrating sphere, LISUN already stop producing it but instead with A-molding technology integrating spheres IS-*MA<\/a><\/p>\n

A Molding Lumen Sphere VS The Traditional Optical Sphere<\/span><\/p>\n<\/div>\n

Specifica:
\n<\/strong>\u2022 Painting material of coating is according to Pubblicazione CIE n. 84<\/a> (1989)
\n\u2022 The sphere walls painting material is BaSO4 coating (PTFE\u00a0material is option): \u03c1 (\u03bb) \u22650.96 (spectral range: 450nm~800nm) and \u03c1 (\u03bb) \u22650.92 (spectral range: 380nm~450nm)
\n\u2022 Fine diffuse with multiple reflections: Reflectance \u03c1\u22480.8 and accuracy of \u03c1 (\u03bb) <1.5%
\n\u2022 Build-in all functional lamp testing jigs: E27, T5\/T8\/T12 tubes and the testing holder base for LED and other luminaires. All samples under test can be installed both up and down directions in the sphere.
\n\u2022 Cavo di alimentazione, morsetto di alimentazione e alloggiamento per lampada ausiliaria sono integrati (la lampada ausiliaria \u00e8 opzionale).
\n\u2022 Il cavo di alimentazione e la presa sono integrati. \u00c8 comodo alimentare la lampada in fase di test.
\n\u2022 Due rilevatore fotografico<\/a>\u00a0porti, uno fibra ottica<\/a> port and temperature sensor hole are built-in
\n\u2022 The traditional integrated spheres is made up of several pieces. LISUN developed A-Molding Technology to produce the integrating sphere which is more round and the test result is with more accuracy
\n\u2022 Build-in cross laser can help to install the standard lamp and the lamp under test in the center of the optical sphere\u00a0(This item is not included for integrating spheres with a diameter less than or equal to 1 meter)<\/p>\n

Applicazione:
\n<\/strong>The optical sphere works with a Spettroradiometro<\/a> to do the photometry, colorimetry and radiometry parameters measurement.
\n\u2022 IS-0.3M\/IS-0.5M \u00e8 adatto per LED, moduli LED, mini lampadine LED e altre piccole lampade. Il campo di misura del flusso luminoso va da 0,001 a 1.999 lm.
\n\u2022 IS-1.0MA \u00e8 adatto per lampadine CFL o LED. Il campo di misura del flusso luminoso va da 0,1 a 199.990 lm.
\n\u2022 IS-1.5MA\/IS-1.75MA \u00e8 per lampade CFL, lampadine e tubi LED, lampade fluorescenti, CCFL. Il campo di misura del flusso luminoso va da 0,1 a 1.999.900 lm
\n\u2022 IS-2.0MA \u00e8 \u043f\u0440\u0435\u0434\u043d\u0430\u0437\u043d\u0430\u0447\u0435\u043do per lampade HID o lampade ad alta potenza. Il campo di misura del flusso luminoso va da 0,1 a 1.999.900 lm.<\/p>\n

How do you clean an integrated sphere?<\/a><\/strong><\/h2>\n

Always keep the internal coating of the integrating sphere clean to extend the service life of the integrating sphere. When not in use, please close the integrating sphere to prevent dust from entering. Use a hair dryer or air compressor to clean the dust inside the integrating sphere at least once a week. When cleaning, avoid using any material to directly touch the integrating sphere.<\/p>\n

What does an integrating spheres measure?<\/a><\/strong><\/h2>\n

The Ulbricht Sphere work with a spectroradiometer to measure single LEDs and LED lighting products. LED\u2019s quality should be tested by checking its photometric, colorimetric and electrical parameters. Please click here to review more details for LPCE-2 High Precision CCD Spectroradiometer Ulbricht Sphere System<\/a>.
\n- Colorimetrico: Coordinate cromatiche, CCT, rapporto cromatico, lunghezza d'onda di picco, larghezza di banda dimezzata, lunghezza d'onda dominante, purezza del colore, IRC, CQS, TM-30 (Rf, Rg), test dello spettro.
\n\u2022 Photometric: Luminous Flux, Luminous Efficiency, Radiant Power, EEI, Energy Efficiency Class, Pupil Flux, Pupil Flux Efficiency, Pupil Factor, Cirtopic Flux, Plant Growth Lamp PAR and PPF
\n- Elettrico: Tensione, Corrente, Potenza, Fattore di potenza, Fattore di spostamento, Armonica (opzionale)<\/p>\n

How do you calibrate an integrated sphere?<\/a><\/strong><\/h2>\n

If the integrating sphere spectroradiometer system is used frequently, it is necessary to use a standard lamp that is still valid and calibrate the system every week. If the system is not used for a long time, it can be calibrated before the next use. Please watch the operation video for all detailed operation:<\/p>\n
