What is the Integrating Sphere?

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

仕様：
• Painting material of coating is according to CIE出版物No.84 (1989)
• The sphere walls painting material is BaSO4 coating (PTFE material is option): ρ (λ) ≥0.96 (spectral range: 450nm~800nm) and ρ (λ) ≥0.92 (spectral range: 380nm~450nm)
• Fine diffuse with multiple reflections: Reflectance ρ≈0.8 and accuracy of ρ (λ) <1.5%
• 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.
• 電源ケーブル、電源端子、補助ランプポジションが内蔵されています（補助ランプはオプションです）
• 電源ケーブルとソケットが内蔵されており、テスト対象のランプの電源を入れるのに便利です。
• 二 光検出器 ポート1つ 光ファイバー port and temperature sensor hole are built-in
• 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
• Build-in cross laser can help to install the standard lamp and the lamp under test in the center of the optical sphere (This item is not included for integrating spheres with a diameter less than or equal to 1 meter)

応用：
The optical sphere works with a 分光放射計 to do the photometry, colorimetry and radiometry parameters measurement.
• IS-0.3M/IS-0.5Mは、LED、LEDモジュール、ミニLED電球、その他の小型ランプ用です。光束測定範囲は0.001～1,999 lmです。
• IS-1.0MAはCFLまたはLED電球用です。光束試験範囲は0.1～199,990 lmです。
• IS-1.5MA/IS-1.75MAは、CFL、LED電球・直管、蛍光灯、CCFL用です。光束試験範囲は0.1～1,999,900 lmです。
• IS-2.0MAはHIDランプまたは高出力ランプ用です。光束試験範囲は0.1～1,999,900lmです。

How do you clean an integrated sphere?

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.

What does an integrating spheres measure?

The Ulbricht Sphere work with a spectroradiometer to measure single LEDs and LED lighting products. LED’s quality should be tested by checking its photometric, colorimetric and electrical parameters.

- 測色色度座標、CCT、色比、ピーク波長、半値幅、優勢波長、色純度、CRI、CQS、TM-30（Rf、Rg）、スペクトルテスト
• 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
- 電気電圧、電流、電力、力率、変位率、高調波（オプション）

How do you calibrate an integrated sphere?

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:
