Precise Light Measurements: The Key to Effective Lighting Solutions

To provide the most accurate and efficient LED lighting solutions, ENIM continuously conducts light measurements in its local laboratory. Advanced “LabSpion®” Goniometer technology quickly and accurately collects light data, which is then processed and presented in various formats and cross-sections using “Viso Light Inspector” software.

How Does the Goniometer Work?

The “LabSpion®” goniometer is an ideal tool for measuring various light sources, from small lamps to large LED panels and Outdoor luminaires. The light source is easily attached to the goniometer and a spectrometer sensor is mounted on a tripod and placed at a distance depending on the size of the luminaire being measured. An integrated laser automatically determines the distance between the two parts, ensuring quick and accurate alignment. The “Viso Light Inspector” software, installed on a laptop, is the most relaible and intuitive light measurement software solution on the market. The measurement data obtained are processed and presented in various formats.

 Spectrum of Data Measured by the “LabSpion®” Goniometer

In the ENIM laboratory, the goniometer measures the following light parameters:

– Lumens: A unit of luminous flux measurement indicating the intensity of the light source, regardless of its direction.

– Lm/W: Luminous efficacy, representing the efficiency of the luminous flux.

– Peak Candela: The maximum light intensity emitted in a specific direction.

– CCT (Correlated Colour Temperature): The correlated colour temperature of emitted light, measured in Kelvin, indicating whether the light is warm (yellow/golden) or cool (bluish). This measurement is crucial in lighting design as it affects the ambiance and functionality of a space.

– CRI (Colour Rendering Index): A colour rendering index showing the light source’s ability to reproduce the colours of objects compared to a natural light source.

– Beam Angle: The angle at which light is emitted from the light source. A narrow beam angle creates focused, intense light, while a wide beam angle produces broader, softer light.

Where Are the Data Used?

As a luminaire manufacturer, ENIM designs and manufactures LED outdoor and indoor luminaires based on precise light flux measurements, continuously improving them and seeking optimal, energy-saving solutions. Operating with highly accurate light measurement data allows for offering the optimal lighting solution for a specific project, adapting to specific requirements. Goniometer measurements can be found in every ENIM LED luminaire specification.

Another practical application of the measurement data is in DIALUX calculations. Lighting professionals use LDT files when designing lighting. On the ENIM website, LDT file data can be downloaded for each product variation by selecting the necessary parameters in the product search filter. LDT files can also be downloaded for the entire product family. This greatly facilitates the work of designers in finding the most effective lighting solution.
