Journal Title: Archives of Materials Science and Engineering - Year 2018, Vol 1, Issue 94
Abstract
Purpose: The purpose of this paper is to study and compare the light and technical characteristics of halogen and LED-lamps and to determine the effect of lighting quality on the accuracy of the measurement of the optoelectronic control system for the micrometer sizes of the prescription objects. Design/methodology/approach: The research approach is determined by the analysis and comparison of the lighting characteristics of lamps manufactured for mass production and the detection of the possibility of using these sources for optoelectronic measuring systems for the micrometric range. Lighting characteristics were investigated by the goniophotometric method and the method of the integration sphere. Findings: During the analysis of the results of experimental studies, a discrepancy in the lighting characteristics of the lamps was found compared to those indicated by the manufacturers. This difference in the indicators of the lighting characteristics was: for the light flux 2.92% halogen lamp (13.4% LED); correlated colour temperature by 0.7% halogen lamp (1.6% LED); for current – 7.34% halogen lamp (8.7% LED); for power – 7.31% halogen lamp (7.54% LED). The accuracy of measuring the size with a halogen lamp is 20 ± 0.96 μm, and with LED – 20 ± 0.23 μm. Research limitations/implications: The result of comparing the accuracy of the measurement for the optoelectronic measuring system of the geometric dimensions is the measure of absolute contrast with the use of LED lighting is four times better than halogen. Practical implications: Using the results of the study of the light characteristics of lamps described in the article, it is possible to improve any optoelectronic measuring system. Originality/value: The originality of the results of the article is the experimental data of the lighting characteristics studies of the lamps used in the optoelectronic measuring system.<br/><br/>
