Abstract: In this study, we consider the ways to enhance the functionality of portable lighting devices which are increasingly used by human in his activities. We considered the influence of the light source used in it on the performance of such a light fixture. In particular, we have showed that the LED use as a light source allows expanding the functionality of a portable lighting device. We considered the options for improving their performance on the example of a portable lighting device with an extension cord. Taking into account the majority of the considered technical solutions, we developed a portable LED lighting device. We considered its structure and purpose of the component elements in detail. For practical verification of the concept proposed, we created a corresponding model of a portable LED lighting device and carried out some studies of its lighting characteristics. The studies have shown that the designed multifunctional portable lighting device provides the same luminous flux as a 60 W incandescent lamp which is usually used in portable lighting devices for local lighting while the light output of the developed lighting device is three times more than the light output of a portable fixture with incandescent lamp.
