How to choose the right lumen Integrating sphere for your needs

How to choose the right lumen Integrating sphere for your needs?

The integrating sphere is a sphere that can be used with Spectroradiometer to test parameters such as luminous flux, color temperature, and light efficiency of a light source. Its working principle is that the light is collected by the integrating sphere through the sampling port, and after multiple reflections inside the integrating sphere.

Measurement results are more reliable when using an integrating sphere to measure luminous flux, which reduces and eliminates measurement errors caused by the shape of the light, the angle of divergence, and the difference in responsivity at different locations on the detector.

When measuring, there are standard lights, auxiliary lights, optical fiber interfaces, etc. inside the integrating sphere. Lumen is the physical unit describing the luminous flux, which is explained by physics as a candle (cd, Candela, a unit of luminous intensity, which is equivalent to the luminescence of an ordinary candle. Intensity) The total emitted luminous flux generated at a solid angle (the angle represented by the spherical cone corresponding to the spherical crown of 1 square meter, which corresponds to the central angle of the mid-section is about 65° on a unit sphere with a radius of 1 meter). The physical formula for luminous flux How to choose the right lumen sphere for your needs:

Therefore, Hangzhou Hopoo Light&Color launched theHPCS6500 high-precision spectroradiometer & integrating sphere system, which mainly tests energy-saving lamps, fluorescent lamps, HID lamps (such as high-pressure sodium lamps and high-pressure mercury lamps), cold cathode fluorescent lamps and LED lamps. The quality of LEDs should be tested by checking their photochromic and electrical parameters. The test results of this system meet CIE177, CIE-13.3, CIE-84, ANSI-C78.377, GB/T 24824, IESNA-LM-63-2, Optical-Engineering-49-3-033602, (EU) 2019/2015 , LM-80 and LM-79 photometric and colorimetric test requirements.

Hangzhou Hopoo Light&Color Technology Co., Ltd. focuses on the production, research and development and sales of lighting and electrical testing instruments. The whole series of products are developed and produced in strict accordance with the requirements of ISO9001:2015; all products meet the requirements of CIE; in addition, All products of hopoocolor have passed CE certification and obtained the qualification to export to the European Union. The main products include goniophotometer, integrating sphere, spectroradiometer, illuminometer, colorimeter, and LED test instruments.
