This article focuses on the production and measurement of incandescent lamps made from polydimethylsiloxane and YAG luminophore. By a suitable combination of these materials along with a light source of a specific wavelength, white colour of light can be achieved. Since the optical power from the light source is fed through a light guide structure to a remote lighting section, the device can be used in hazardous environments such as mines or factories where electromagnetic interference is likely to occur. The study describes temperature characteristics and chromaticity temperature changes of the designed lamp for different luminophore concentrations.

1. Introduction Polydimethylsiloxane (hereinafter referred to as PDMS) has been primarily designed to encapsulate photovoltaic cells, printed circuit boards, transformers, current sources, thermally stressed cables, optical connectors, etc. [1-3]. Later, it also began to be used for other purposes because it conveniently combines mechanical, electrical and optical properties. In the 3D printing technology using the method of DPL (Digital Light Processing), it is used for the production of a printing base and is also widely used for fine lithography techniques, especially for the creation of microfluidic and microengineering systems - MEMS (Micro Electro Mechanical Systems). For example, the authors of the publication  describe an optical biopsy microsystem technology that has smaller dimensions (11.2 x 18.6 mm) compared to other systems and reduced power consumption. The microsystem includes an image magnification optical microsystem (IMOM) and light emitting diodes (LED). Microlenses made from PDMS are integrated into the IMOM subsystem to achieve image magnification and to improve LED illumination. Other interesting solutions in the field of MEMS systems are described by authors of publications [5-10]. Publication  describes a new construction of a hybrid multichannel optical sensor system designed to monitor patient's vital functions. The noninvasive measuring probe is based on two FBGs encapsulated in the polymer; the authors selected the PDMS polymer because it is inert. There was no deformation of the FBG sensors in the vulcanization process; after the vulcanization, a fourfold increase in temperature sensitivity was observed compared to the nonencapsulated FBG. The probe and the associated multichannel system offer the ability to monitor the basic vital functions (body temperature, heart rate and respiratory rate) in up to 128 patients. The same issue is addressed by the authors of publications [12-15]. Ot [...]
