Regarding the LED lamp beads, what is its advantage? The cob in the LED lamp. The shape of the led lamp bead has undergone in-line insertion and patch. With the advancement of technology, it is a matter of course that multiple led light-emitting chips are highly integrated and directly packaged on the substrate (integrated design of circuit and heat dissipation), forming a compact structure, high power, and large size. Power led light-emitting element, this is "COB" (seemingly a lamp bead, theoretically a group of lamp beads).

As for the patch, what are its advantages? Integrated LED is generally a nickname for COB light source in the market, but in theory, the characteristics of COB light source cannot be clearly described. COB refers to Chip-On-Board, which directly encapsulates low-power chips on aluminum substrates to quickly dissipate heat. The chip area is small, the heat dissipation efficiency is high, and the drive current is small. Therefore, it has high heat dissipation with low thermal resistance and high thermal conductivity. Compared with the general SMD low-power light source characteristics: higher brightness, small thermal resistance (

If the light is on, it means that the function of the lamp bead is not hindered at all. If the light is not on, exchange the red and black test pens and test again. Avoid the cathode and anode of some lamp beads that are opposite to the general ones. The lamp beads are lit to observe the color of the lamp beads, whether the color temperature can meet the requirements. Whether the brightness is suitable. Choose suitable lamp beads. Therefore, we found that both of them have their own advantageous addresses.
