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...

What is the goniophotometer？ The goniophotometer is the main measuring equipment for the light distribution performance test of lamps, which can be used to measure the spatial light intensity distribution, total light flux and lamp efficiency of lamps or light sources. The goniophotometer system consists of precision turntable and control system, spectrum analysis system, standard lamp, alignmen...
Definition of light intensity: Light intensity is referred to as light intensity. The international unit is candela, which is short for CD. Other units include candlelight and candlelight. 1CD, i.e. 1000mcd, 1 candela refers to the luminous intensity of light from a monochromatic light source (frequency 540×10 ^ 12Hz) in a given direction (the radiation intensity in this direction is 1 / 683 ...
The Goniophotometer is the main measuring device for the light distribution performance test of lamps and lanterns, which can be used to measure the spatial light intensity distribution, total luminous flux and efficiency of lamps and lanterns. The composition of the Goniophotometer system includes: precision turntable and control system, spectral analysis system, standard lamp, alignment system, ...
LM-79 and LM-80 are energy efficiency standards approved by IESNA for LED product testing. LM-79 test refers to the photoelectric measurement of solid-state lighting products, mainly testing the luminous flux, light intensity, color degree, etc. LM-80 luminous flux maintenance rate (LED) life standard mainly tests the maintenance rate of luminous flux output, that is, the life test of LED light so...
