Abstract
V diplomskem delu so opisani preskusi, ki so aplikabilni za operacijsko svetilko tako po medicinskem osnovnem standardu IEC/EN 60601-1:2006+A11:2011+A1:2013, kot tudi dodatnemu IEC/EN 60601-2-41:2010. Na začetku predstavim, zakaj potrebujemo standard in vsakega posebej opišem. V nadaljevanju je opisana črna soba oziroma fotobiološki laboratorij. Ta del nam pove, zakaj je potrebno izvajati preskuse v takem okolju in kako ljudje zaznavamo svetlobo. Spoznamo tudi instrumente in pripomočke, katere sem potreboval za izvedbo meritev. Sledi opis operacijske svetilke in njenih lastnosti. Nato se začnejo opisi in razlage preskušanj, ki sem jih opravljal v fotobiološkem laboratoriju. Preskusi si sledijo po vrsti, kot je to zapisano v standardu. Od meritev sredinske osvetlitve, premera svetlobnega polja, vpliva senc, globine osvetlitve do ostalih preskusov, ki se navezujejo na barvno temperaturo, CRI indeks, UV svetlobo, barvni prostor. Po končanih fotobioloških preskusih pa sem se osredotočil na električne preskuse, ki jih zahteva osnovni medicinski standard. Tu govorim o več različnih preskusih, za vsakega razložim, zakaj ga izvajamo in kako so potekale meritve. To so meritve porabe, temperaturni preskusi, prebojna trdnost in še nekaj ostalih. Omenim tudi določene mehanske preskuse, ki jih je bilo potrebno izvesti. Za zaključek pa razložim, kaj sem se naučil in predstavim možne izboljšave za natančnejše meritve osvetljenosti.

Title:Testing of the surgical light
Abstract:
This diploma thesis presents description of test procedures which are applicable for surgical luminaries according to the basic medical standard IEC/EN 60601-1:2006+A11:2011+A1:2013 and additional standard IEC/EN 60601-2-41:2010. Initially, I introduce basic needs for standardization and describe each standard one by one. The description of a black room also known as photobiological laboratory is followed next. This part talks about why tests have to be performed at a specific environment and how people perceive light. Instruments and other accessories which are used for measurements are described. Then we continue with a description of an operation lamp and its properties. The main part of this thesis are descriptions and explanations of tests which have been done in photobiological laboratory. Tests are performed in sequence according to the standard. From measuring central illuminance, light field diameter, shadow dilution, depth of illumination and other test procedures which are related to color temperature known as CRI index, UV light and color space. After photobiological test have been performed, the main focus was on electrical tests which are required by medical standard. Each test is explained and the reason why it was performed, for example input test, temperature test, dielectric strength test, mechanical tests and few others. Finally possible improvements for more accurate measurements of illuminance are described.
