The integrating sphere is a sphere having a reflective covering on the interior. It is used as lead light test equipment. Typically, one would place a light source inside it to measure the source’s overall flux output. All the beams emitted by the item are gathered together after being reflected off the inner reflecting covering of the spherical. Named because of how well it integrates the m...
Integral sphere measurement system is the most common light color measurement equipment in the luminaire industry, and its measurement results can meet the needs of most product development and testing, which is a relatively economical measurement method. The following is a brief introduction to the working principle of the integrating sphere measurement system and its measuring method of the inte...
If your application requires measurement of a widely diverging beam, an integrating sphere is the best option to consider. An integrating sphere is an optical component that captures a light beam and enables you to measure the power in the beam under conditions that would otherwise be very challenging. A widely diverging beam that might overfill a regular sensor aperture. Sphere integration LPCE-2...
The standard specifies that the size of the integrating sphere is based on the size of the lamp under test. But experts explain that for many product development and testing purposes, smaller spheres can provide acceptable measurement accuracy. 1. What is the function of integrating sphere and what is integrating sphere? 1.1 Integrating sphere instruction: The integrating sphere is a quick and con...
Foreword: With the rapid development of the LED industry, the application range of LED lamps is becoming wider and wider, and there are more and more types of lamps. Flat light is one of them. Flat light is suitable for indoor lighting such as living room, bedroom, corridor, kitchen, viewing balcony, etc. At the same wattage as traditional lighting sources, flat panel lights are energy efficient, ...
The integrating sphere is a cavity sphere coated with a white diffuse reflection material on the inner wall, also known as a photometric sphere, a luminous sphere, etc. One or several window holes are opened on the spherical wall, which are used as light inlet holes and receiving holes for placing light receiving devices. The inner wall of the integrating sphere should be a good spherical surface,...
Generally speaking, the optical diffuser, when used carefully, can reduce the small errors caused by the uneven distribution of the incident light source on the detector or the deviation of the beam during measurement, so the accuracy of the integrating sphere measurements can be improved. However, in precise measurement, an integrating sphere must be used as an optical diffuser to minimize the ab...
1. Operation steps: 1. First connect the probe and optical fiber to the corresponding position of the integrating sphere, and fix it. 2. Turn on the DC power supply of the integrating sphere system configuration. 3. Turn on the computer, then open the computer desktop test software, and select “System Settings” on the software, and connect the DC power supply, the electric parameter me...
HID lamp is high intensity discharge lamp. High pressure sodium lamp, high pressure mercury lamp, xenon lamp, metal halide lamp are all belong to HID lamp. We generally use Integrating Sphere Spectroradiometer Test System to test the photometric, colorimetric and electrometric parameters. Generally we suggest the diameter size of Integrating Sphere according to the size of lamp under test. If yo...
From the perspective of the LED product structure and technology development, the quality criteria of LED product mainly consider the parameters of the optical properties, electrical properties, thermal properties, radiation safety and life. LED optical properties mainly involve luminous flux, radiation flux, luminous efficiency, chromaticity coordinates, correlated color temperature, color render...
IES LM-79 “Electrical and Photometric Measurement of Solid-State Lighting Products” as the exclusive international standard for measuring the total luminous flux, electrical power, luminous intensity distribution and correlated color temperature (CCT), color rendering index (CRI) and other colorimetric parameters of solid-state lighting products (SSL), it highlights the total luminous flux of ...
Integrating sphere is a hollow sphere with high reflectance surface, it is widely applied in testing lumen, chromaticity coordinates, CCT, dominant wavelength and peak wavelength etc for light source or luminaries. Here we talking about integrating sphere theory. The inner coating reflectance of integrating sphere is an important index for integrating sphere. The coating is ideal diffuse reflectio...
