1. What is COB Strip Light? In the LED world, COB is the abbreviation for Chip on Board, which basically means to package the LED die directly on the circuit board (PCB). The ‘Chip on Board’ LED used on flexible strip lights is also sometimes called a flip-chip. Flip chip LEDs are basically a bare bones approach to LED structure. Take a look at the normal 5050 SMD (surface mount device)LED, it has a bulkier plastic reflector that encapsulates the LED diode itself and then covers that with a phosphor coating. The ‘flip chips’ that make up COB LED strips cut everything from their design except an LED chip, the yellow phosphor covering, and connection pads. This condensed design leads to a significant reduction in size, allowing them to be packed closer together and further miniaturize LED based lighting. 2.What is the difference between LED and COB LED? The main difference between these two technologies a side from the efficiency is the way in which the LEDs are mounted to the tape. COB LEDs are mounted directly into the circuit board with a strip over the top acting as a ‘diffuser’ enabling a seamless finish when illuminated. Being directly mounted to the circuit board means there is room for more LEDs to be mounted. Our COB LED tapes typically achieve 320, 480, 528 LEDs per metre. Compare this to current traditional LED Tape and the use of SMD (Surface Mounted Diode) Technology, where the LED chips are mounted and secured on top of the circuit board and typically the maximum number of LEDs per metre is around 240. The SMD version is much more likely to cause spotting and dark spots due to the spacing of the chips on the LED Tape, especially when installed into LED channel with a semi clear, or transparent diffuser over the top. 3.Why Choose Greeland COB LED Tape? This tape is manufactured using the highest quality components available on the market for the price making it a professional and commercial grade product. Greeland LED COB Tapes carry a typical lifespan of 25000 Hours and come complete with a 3-year guarantee to ensure superior quality and continued high performance. 4.Can you cut COB LED strips? How to cut led light strips? To cut the COB strip, you only need a pair of scissors. Of course, use a ruler to measure the length you need before cutting it. The PCB board of the light strip has clearly marked the places that can be cut, and it can be cut along these lines.
