LED strip lights are an endless source of interior design ideas due to their wide range of application. Although rope lights already existed with incandescent lights, their use and features can hardly be compared to LED strip lights' despite their similarity in looks. While rope lights are exclusively for decoration, and have a 360° beam angle – so they illuminate their entire surroundings – LED strips can be used for task lighting as well, or tightened on flat surfaces lighting to one direction only.
The power/brightness of a strip varies depending on the number and size of the LEDs it uses. The LEDs used by strip lights are actually a compact version called SMDs (Surface Mounted Devices), which come in two main sizes; small (3.5m by 2.8mm) and large 95mm by 5mm). The number of LEDs per meter will vary, and, as a rule of thumb, the greater the number of LEDs, the brighter the strip.
Now, with the development of the LED technology, user can enjoy the RGB LED strip light in order make a colorful and unique night. RGB LEDs basically contain three LEDs used in one. The combination of these three colors covers the full spectrum of colors. The RGB controller works with PMW (pulse-width modulation), which means – at a certain frequency – it turns the LEDs on and off fully (this is exactly the same technique single colored LEDs are dimmed). If you turn the blue LED off completely for instance, the red and green will create a yellow light together. The color can be manipulated with the frequency of the individual LEDs on and off modes. If you add a bit of blue to this yellow, you will receive a lighter green shade. anty881209wong 140225
