Detailed operating method of goniophotometer

Although many types of goniophotometers have appeared in the market in recent years, especially the continuous technological innovation has greatly enhanced the operating function of such photometers, its basic principle and operating method have not changed much. Therefore, before using this kind of goniophotometer, it is necessary for users to understand its detailed operation method.

Goniophotometer is an instrument for quantitative and qualitative analysis of substances by spectrophotometry. It is mainly used for measuring the light distribution performance of lamps and light sources, i.e. the width and color metric value distribution of lamps and light sources in different directions. The principle of spectrophotometry is to analyze the substance qualitatively and quantitatively by measuring the absorbance of the substance at a specific wavelength or within a certain wavelength range. With the continuous development of the photometer industry, more and more enterprises and industries have applied the goniophotometer, and a large number of enterprises have entered the goniophotometer and developed.

The goniophotometer is mainly divided into two types: horizontal and vertical. It is mainly used to test the lumen, light distribution curve, glare level and isoilluminance distribution diagram of the whole lamp. Another main function is to export ies or LDT files. (the goniophotometer system can also add a spectrometer and a color probe to form a system for spatial spectral distribution test.)

The goniophotometer can mainly measure the light intensity distribution curve, light intensity data, beam angle, total light flux, lamp efficiency, regional luminous flux, upper luminous flux, lower luminous flux, brightness distribution, utilization coefficient, brightness limit curve, glare level, minimum allowable distance ratio, equal illuminance curve, effective average illuminance curve, spatial color distribution, average color parameter, etc.

Before operation, the tester of the goniophotometer needs to check whether the signal line, control line and power line of each part of the goniophotometer system are connected normally. The system turns the key switch on the cabinet panel to turn on the main power supply, then presses the “motor” button to turn on the power supply of the mechanical part, presses the “meter” button to turn on the power supply of the photometric tester and the angle measurement and control instrument in the cabinet, and then presses the electric meter switch to turn on the power supply of the electric meter. Observe whether each test instrument in the cabinet is connected to the mechanical part normally.

Under normal conditions of the goniophotometer, except that all reference signals in the instrument display “0”, other data are displayed immediately; If “0” is displayed, it indicates that the connection between the test instrument and the mechanical part fails. Turn off the power supply of each instrument in the cabinet and turn it on again.

After purchasing the goniophotometer, the first thing is to have a detailed understanding of the operation method of the photometer, so as to enhance the use performance. Then, choose a photometer brand with superior quality and perfect after-sales service.
