How can you use Type C Goniophotometer to measure lighting sources

A goniophotometer is a tool used to determine an instrument’s luminosity. It does this by evaluating the 3D curve of the light intensity distribution. LISUN’s goniophotometer- LSG 6000 is typically used to measure the radiance or brightness of equipment. It gauges how bright indoor spotlights, street lamps, or car lights are. It assesses how evenly the light intensity is distributed in space. This article will describe goniophotometers , their use, and their operation and briefly discuss Gonio spectrometers.

LSG-6000 Goniophotometer (Mirror Type C)
A goniophotometer uses a technique for sensing light that automatically distributes intensity over a 3D curve. Its measuring range is between 5 to 30 meters. All forms of illumination sources can be measured by this device such as LEDs and plant lighting. HID lights such as indoor and outdoor luminaires, roadway lights, and street lamps can also be measured by this device.

One specific characteristic of the LSG-6000 goniophotometer is that it can simultaneously measure the vertical and horizontal axes. It acts as a tool that calculates how much light is directed in a specific direction. The results can be exported as CIE, IES, LDT and other format files. By connecting a goniophotometer via USB to a PC, English version software can be operated on Windows 7, 8, 10, or 11. One of the key factors contributing to the goniophotometer’s importance is the production of photometric data files. The photometric data is entered into lighting design software to reproduce the level of illumination and beam pattern on a surface. It enables lighting plans to be created without requiring time-consuming and expensive physical models.

Knowing the specifications and features of the goniophotometer is also important. It must be noted that the angle decode system and the rotary motor of the goniophotometer are both from Germany and Mitsubishi Motors. They aid in the device’s accurate and smooth rotation. When it starts and stops, it is quite stable. Moreover, the devices ‘near the field detector and large mirror move in tandem in a straight line. The far-field detector detects light coming directly from the luminaries. All the while the huge mirror and far-field detector move synchronously. During all of this, the burning position of the luminaries remains unchanged.

Additionally, the LSG-6000CCD hardware and software support the IES/LDT file export as well as the plant lighting PAR, PPF, and PPFD spatial distribution tests. The test luminaire rotates around the mirror with a vertical axis angle of 180 degrees (or 0-360 degrees), and it also rotates around itself with a horizontal axis angle of 180 degrees (or 0-360 degrees).

Uses
LISUN is one of the most renowned manufacturers of goniophotometers. As discussed earlier, the LSG-6000 goniophotometer is particularly used to assess the luminous flux of directed light sources like LEDs and car headlights. It is a photometric device used to quantify a light source’s perceived strength at various angles. A goniophotometer has several purposes. One of its most common applications is as an automated system for testing car lights. It determines how strong a vehicle’s light is.

The fact that LISUN’s goniophotometer is generally utilized for directed light sources is an important consideration while using it. This implies that measurements made with such a meter will yield more accurate results for unidirectional lights. The tool can also act to check temperature and color uniformity. This quality can be useful if the device has color sensors.

How does an LSG-6000 Goniophotometer work?
The goniophotometer made by LISUN has a stationary detector, which needs to be emphasized. It also uses a rotating light measurement approach. The two-dimensional rotating worktable’s center of rotation and the measurement lamp’s luminous center are lined up by the laser beam from the laser sight. The detector measures the light intensity values in all directions on the horizontal plane at the same height as the worktable’s center. The lamp rotates around its vertical axis while performing this. As the light source turns along its horizontal axis, it continuously measures the amount of light in the vertical plane in all directions. The continuous rotation range for the horizontal and vertical axes is 0° to 360°.

The computer may determine additional luminosity parameters and light distribution curves once the light intensity distribution data of the lamps in all directions according to the measuring lights have been obtained.

The apparatus also uses type C motion, which holds the object tested vertically with its base facing up or down. The lamp’s orientation with respect to gravity is constant throughout a measurement.

Gonio spectrometer:
A mechanical or robotic jib supports the luminaire measured in a conventional goniophotometer. Additionally, it features a photometer or spectrometer that enables one to change the distances between the luminaires to provide a spherical locus.
It is essential to look at the optical data of the angle of spectral radiance. This is because it makes it possible to determine the total luminous flux, spectrum radiant flux, and color quantities. It allows for the detection of the color of the material itself. It also helps detect the spatial distribution of reflected (or transmitted) light at user-selectable illumination and detection angles.

FAQs
What is the procedure for the installation of the LSG-6000 Goniophotometer?
LISUN, one of the best and most professional organizations sends its engineers for the installation of the device. These professionals in addition to properly installing the device ensure it is properly functioning and facilitate the customer as best as can be.

Is the goniophotometer compatible with mainframe computers and other devices and can data be transferred?
One can utilize a USB cable to connect the goniophotometer to a computer. Software in the English language can be used with Windows 7, Windows 8, Windows 10, and Windows 11. The LISUN goniophotometer software also supports exporting files in the CIE, IES, LDT, and other formats. Other lighting and luminaire design tools, such DiaLux, can use these format files.
