The topic of the thesis deals with the production of RGB LED light. For this purpose, a special circuit is needed to control the brightness of the LED. The first chapter focuses on the integrated circuit and its operation with a greater emphasis on the data that are relevant to this task. In the second chapter, I will describe the transistor and its use with LEDs.
The LED lamp consists of two circuits, because I wanted to reduce the size of the housing they are inserted into. On the first circuit, we have diodes that are connected to the other circuit. Over 3 rotary potentials on the other circuit control the speed of the LED flashing, which is seen as a change in the brightness of the LED.
From the mechanical point of view, the design and the physical manufacturing of the LED lights and the production of circuits are important. The focus is on the integrated chip 555 timer, which is a key component of the device. The designs of the lamp housing and described elements are provided, which enables the integrated chip to control the brightness of the LEDs.
