Analyzing of chromaticity temperature of novel bulb composed of PDMS and phosphor

Popis výsledku v původním jazyce

The authors of this article focused on the issue of measurement of the chromaticity temperature of proposed bulbs made from polydimethylsiloxane, depending on the temperature of proposed bulbs. The advantage of this solution is the immunity to electromagnetic interference (EMI) and the ability to use, for example in dangerous environments (such as mines, factories, etc.). For the realization of incandescent bulbs was used transparent two-component elastomer Sylgard 184. A mixture of polydimethylsiloxane (PDMS) and a curing agent in a defined ratio (10:1) and admixture with garnet phosphor YAG: Ce was cured in the temperature box at temperature 90°C ± 3°C in the shape of the bulbs. All experiments were realized with eight different weight ratios of phosphor and Sylgard 184. Optical power (5 W) from a laser with a wavelength of 455 nm was fed to the proposed bulbs using the cylindrical waveguide of polydimethylsiloxane with a diameter of 5 mm. Chromaticity temperature was measured by two temperature sensors for 12h. The outcome of this study is the evaluation of the chromaticity temperature of output light depending on temperature variations of proposed bulbs due to the conversion of optical power into heat.
