In this category you can find LED strips and aluminum profiles. The ordinary RGB LED strip is still the most widely distributed thanks to its low price. The first generation RGB LED strip SMD 5050 have an operating voltage of 12V and LEDs in groups of three. The use of aluminum profile for LED strip is recommended when you want to embed a given LED strip in the floor or wall. Moisture-proof LED strips, with their protective cover, which is usually a special silicone can be used without any problems for bathroom lighting, in rooms with moisture or for outdoor lighting (facade lighting, advertising panels, etc.). For greater efficiency, flexible LED strips are installed in aluminum profiles specially created for this type of lighting. SMD diodes are mainly used for the production of LED strips. SMD means surface mount device. Because of its bright light output and wide-angle radiation, the SMD diode is used in the production of rigid and flexible LED strips. LED strip 3528 is one of the most popular LED strips. The size of the SMD diodes used is 3.5x2.8 mm. It is used in the production of single-color or RGB LED strips. LED strip 5050 uses the complex SMD 5050 diode (5x5 mm). SMD 5050 diode is widely used for single color, for RGB, as well as for digital LED strips.
