The meaning is different, the chip used is different, and the bracket used is different.
Different meanings: COB refers to the chip is directly packaged on the whole substrate, that is, N chips are integrated together on the substrate for packaging. LED light is a light-emitting diode, is the use of solid semiconductor chip for light emitting materials. Compared with traditional lamps, LED light energy, environmental protection, color and response speed is good.
The LED chips used are different: the COB light source is mainly low-power LED chips less than 1 watt, and the high-power LED chips over 1 watt are also used for a very small amount of COB light source. LED integrated light source is generally used more than 1 watt of large size high-power LED chip, chip size is generally more than 30MIL.
The supports used are different: the supports used by the COB light source have a variety of sizes, including dozens of square, rectangular, oval and other sizes. The material is mainly aluminum, but there are also copper and ceramic supports, generally without side feet. The support used for LED integrated light source is only 10W, 100W, 500W and other square support, whose material is mainly copper, and the support has two side feet.
cob light source is also a kind of led light source, but it is an integrated package led light source (refer to the following figure).
As for cob and led spotlights, which are good, you can choose china cob led strip, but the cost of cob light source itself is higher, the overall heat dissipation performance is better than the general led light source.
