In recent years, with the growing energy crisis and the increasing awareness of environmental protection, LED bulbs have become a popular choice as energy-efficient lighting products. However, due to the presence of various brands and models of LED bulbs in the market, consumers often find it difficult to judge their quality and performance when making a purchase. Therefore, it is crucial to estab...
With the development of technology, LED lighting has been widely used in the field of illumination. In order to ensure the quality and performance of LED lighting, it is necessary to test LED lighting. This article will introduce large and small integrating spheres and the integrating sphere testing system as an efficient and accurate method for testing LED lighting. 1. Large integrating sphere A ...
As an emerging light source, LED is very different from the traditional light source in terms of its own structure and luminous characteristics. Due to the self -absorption effect of the LED itself and the measurement error brought by the internal shield of the integrating sphere, the LED’s optical flux error is measured with a large amount of optical flux errors. The position and gear scree...
Introduction Spectroradiometer integrating sphere systems are now standard equipment for researchers working in the area of light measurement and characterization. These cutting-edge devices are vital for determining the efficiency, reliability, and uniformity of lighting in a wide range of applications. Research, product development, and quality control are just some of the many areas that benefi...
Lumen is a unit of measurement for the total amount of visible light emitted by a light source. It is an important parameter in lighting design and evaluation, as it reflects the brightness and effectiveness of a lighting system. To accurately measure lumen output, a spectroradiometer system with an integrating sphere is commonly used. In this technical article, we will discuss how to test lumen b...
Integrating sphere, also known as a LED Measurement System, is a hollow spherical shell. Integrating spheres are usually made of metal materials and have an inner wall coated with a white high diffuse reflectance layer (typically magnesium oxide or barium sulfate), ensuring uniform diffuse reflection at every point on the inner wall. There are also integrating spheres made of high reflectance pol...
Introduction High precision spectroradiometer integrating sphere systems rely heavily on temperature regulation to get precise and repeatable readings. Temperature fluctuations may cause measurement inaccuracies and inconsistencies because of their impact on the system’s performance and stability. In this article, we discuss the significance of temperature control in spectroradiometer observ...
What is a integrating sphere: The integrating sphere is also known as a hollow sphere with a highly reflective inner surface. It is mainly a high-efficiency device that collects the scattering or emission of light by samples placed inside or outside the ball and close to a certain window, or the light emitted by the light source itself. It can be used to accurately measure the optical reflection ...
Integrating Spheres can conveniently lumen measurement and test radiation power of light sources, thus it can be used for testing various lighting products. What is an integrating sphere? An integrating sphere, also known as a photosphere, is a hollow sphere with a highly reflective interior surface that is used as an efficient light-gathering device to collect the scattered or emitted light fro...

LPCE-2 (LMS-9000B/A) Integrating Sphere Spectroradiometer LED Testing System is for single LEDs and LED lighting products light measurement. LED’s quality should be tested by checking its photometric, colorimetric and electrical parameters. According to CIE 177, CIE84, CIE-13.3, IES LM-79-19, Optical-Engineering-49-3-033602, COMMISSION DELEGATED REGULATION (EU) 2019/2015, IESNA LM-63-2,...
The inside of an integrating sphere is hollow and coated with a highly reflective white material. One may use such led testing equipment to determine the overall luminous flux of a lamp or the laser’s output power. You may consider integrating spheres as a hybrid between cosine correctors and lenses-only optics. To function, instruments like spectroradiometers need to be linked to a calibrat...
