Urgency of the research. According to the state standards of Ukraine, the quality assessment of lighting devices is carried out according to the following characteristics: light output, light flux, average service life. Therefore, there is a need for an instrument that can measure these characteristics.
Actual scientific researches and issues analysis. Our analysis of publications has shown that methods for assessing the quality of lighting are complicated, and devices are expensive.
Uninvestigated parts of general matters defining. We have proposed a cheaper universal instrument for determining the efficiency of light sources, the main components of which are digital luxmeters and digital wattmeter. In the Articleis considered one of the main components of a universal device - digital luxmeter.
The research objective. For a universal device for determining the efficiency of light sources is needed a digital luxmeter, which allows determining the magnitude and distribution of the surface illumination.
The statement of basic materials. The sensors of our own developed luxmeter are photoresists connected to the Arduino Nano platform. The Article highlights the structure, manufacturing technology, calibration methods and software of this digital luxmeter. Also the technique of work with the device is considered..
Conclusion. Our own developed luxmeter is a prototype of a more complex and high-quality device. The next stage in the development of a universal device for determining the effectiveness of light sources is manufacture of a digital wattmeter. The software for the device operation was developed, the device calibration and developed method of its use was done.
