Introduction In recent years, the demand for high-efficiency lighting systems has increased due to global energy-saving initiatives. This trend has resulted in the widespread use of energy-saving lamps, fluorescent lamps, high-intensity discharge (HID) lamps, and especially light-emitting diode (LED) lamps. Accurate photometric and colorimetric measurement of these light sources is essential for e...
Abstract The demand for efficient and reliable lighting solutions has led to various light sources, including bulb lights, PAR lamps, LED lights, street lights, and tubes. This study aims to compare the luminous performance of these light sources using the LISUN LPCE-2 (LMS-9000) integrating sphere system. Key parameters analyzed include luminous flux, luminous efficacy, and power consumption. Int...

In photometry, the measurement of the power of light is carried out using two different instruments: a goniophotometer and an integrating sphere. Both have their own salient features which make them appropriate for different types of flux testing and measurement. Although they are used for the same purpose i.e. optical power measurement, they have different characteristics and principles. While it...
Household power supply specifications will vary by region, but generally speaking, voltage values are usually between 100V and 240V, while the most common frequency values are 50Hz and 60Hz. Factories using polyphase power will have more differentiated power supplies with higher voltages and more specialized plugs and sockets for larger equipment, but will still use the general power supplies show...
Introduction An integrating sphere is a spherical device used to measure the optical properties of materials. It is a hollow sphere coated with a highly reflective material on the inside surface. The sphere is designed to uniformly distribute light from a source to the sample and collect the reflected light from the sample. Integrating sphere are used in a wide range of applications, including lig...
The special light source hanging in the stalls is also known as the “freshness lamp”. By adjusting the color, brightness, and color temperature of the lighting, it makes the ingredients appear fresher and more glossy. It is often seen in agricultural markets, supermarkets, and other consumer places. The “freshness lamp” has received widespread criticism from the public as i...
Introduction Numerous scientific, industrial, and commercial endeavors rely on precise light measurement. High precision spectroradiometer integrating sphere systems have been developed as potent instruments to address the requirement for accurate light characterization. The precise and consistent measurements made possible by these cutting-edge devices are invaluable to scientists, engineers, and...
