LED - Technical Notes

The latest LED improvement has been “Chip On Board” or COB innovation.  A COB (Chip-on-Board) is an LED packaging technology that describes mounting multiple LED chips directly onto a substrate to form a single module.    Multiple LEDs, minuscule in size, are wired and packaged together into a single ceramic or copper board so that they function as a sole light source. ​ They are sometimes nicknamed “fried eggs” (when they are not lit) because of their yellow phosphor circle on a white board. COBs are made up of multiple chips, usually with a minimum of 9 on a board.  Due to the small size of the LED chips (imagine a quarter), Chip-on-Board technology allows for a much higher packing density than surface mount technology (SMD). COB chips only have 1 circuit and 2 contacts, regardless of the number of the diodes. When a COB LED package is energized, it appears more like a lighting panel than multiple individual lights as usually the case with other LED packages, li...

It is becoming increasingly important for companies to become eco-friendly. Customers increasingly want environmentally friendly options and using an environmentally friendly light source can help companies reduce their energy use, as well as attract a socially conscious consumer base. The energy sector contributes up to 40% of the global carbon footprint. This means that we need efficiency in the energy sector. Light Emitting Diodes, LED lights, is one of the most energy-efficient lighting technologies. LED bulbs save more than 80% of energy when compared to incandescent bulbs.  LED lights consume less energy LED lights need significantly less energy to be bright, unlike other traditional luminaries. In some cases, LED Lights can save more than 85% on energy consumption. Fewer watts per bulb saves energy which means less energy is needed. On a traditional bulb, you will get as much as 20 lumens per Watt. In a LED bulb, one Watt can light up as many as 100 lumens....
