Abstract

The invention provides a combined distributed photometer, which can be used for different lamps and the measurement of a plurality of parameters. The combined distributed photometer comprises a main supporting structure rotating around a vertical main shaft, wherein the main supporting structure comprises a horizontal turntable part and a bracket part of a horizontal rotating shaft; and the horizontal rotating shaft is positioned above a horizontal turntable. The distributed photometer is also provided with a first bracket detachably connected with the horizontal rotating shaft, a second lamp mounting bracket detachably connected with the horizontal rotating shaft, a third bracket, a fourth bracket, and a fifth bracket detachably connected with the horizontal turntable. The combined distributed photometer takes the main supporting structure as a platform, can measure the plurality of parameters of the different lamps and flat-panel displays through flexible combination and is adapted to using requirements, such as multifunction and multiple purposes, of users on the distributed photometer so as to serve as an optimal testing center capable of accurately measuring the luminous flux of a light source, transmitting a luminous flux standard, bringing great convenience to the users and reducing the equipment investment of the users.

Description

technical field [0001] The invention relates to a goniophotometer. Background technique [0002] A goniophotometer is an expensive luminaire measurement instrument. In the past, each type of goniophotometer was only aimed at certain lamps, and could only measure one or several parameters, with limited functions. Some large-scale distributed photometers cannot accurately measure the luminous flux of the light source due to the long distance of the photodetector. At the same time, with the development of display technology, some measurement units need to measure large-scale displays such as LCD TVs (LCD), plasma TVs (PDP), LED displays, etc., but there is currently a lack of measuring equipment for their luminous flux. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a combined goniophotometer that can be used for different lamps and measure various parameters. For this reason, the present invention adopts the fo...
