How does a COB LED work? What are COB LEDs? Relatively new to the LED market, chip on board (COB) LEDs offer many advantages over the standard options. COB LEDs are basically multiple LED chips (typically nine or more) bonded directly to a substrate by the manufacturer to form a single module. Since the individual LEDs used in a COB are chips and not traditionally packaged, the chips can be mounted such that they take up less space and the highest potential of the LED chips can be obtained. When the COB LED package is energized, it appears more like a lighting panel than multiple individual lights as would be the case when using several SMD LEDs mounted closely together. LEDS Typically, LEDs used as grow lights for indoor gardens include an array of colors to help mimic that of sunlight. So, plants get a spectrum of red and blue lights, along with green sometimes (these sometimes appear white). You may have seen these spread out in grow lights that are large with each individual LED encased in a tiny bulb. COB This stands for “chip on board,” and it’s a way of clustering LEDs in a concentrated area. When it’s turned on, it looks like a single light, rather than an array of tiny lights like a spider web. These lights are usually housed in ceramic, copper, or aluminum, which acts as a heat sink to help dissipate heat generated by all those little lights. Why Growers Are Crazy For COB LED Grow Light? Electrical Efficiency Efficiency is measured in µmol/j, which is the amount of photo synthetically active photons that can be produced per watt that is consumed at the wall. The process is interpreted as µmol per watt. The efficiency of a COB LED grow light is about 130140 lm/watt. Low Heat Output Heat ventilation in COB LED grow lights are ideal. The LED grow lights produce strong light without emitting a great deal of heat. Some high-end COB grow lights have a quality substrate that boasts fans and drivers to reduce heat output even more.
