COB strip is compared with SMD strip
The material analysis
The materials used in traditional lamp belt are: flexible circuit board PCB, LED lamp bead, solder paste, coil, gum;
COB lamp belt materials are: LED chip, flexible circuit board, silica gel, solder paste, reel, gum.
Technology analysis
The traditional lamp belt adopts THE SMT SMT process, welding the lamp beads on the circuit board through the SMT process, and then coating glue to achieve waterproof grade.
COB lamp belt by packaging manufacturers adopt high precision flip process to directly fix the LED chip on the PCB board, and then directly achieve the luminous color and waterproof effect through silica gel coating.
Cost analysis
LED traditional patch lamp belt has been developed for more than ten years, each supply chain and suppliers are very mature, each supply chain competition is fierce, the market is transparent, at present, businesses are small profits but quick turnover business model, and COB lamp belt product development cycle is short, in the short term, the cost is not as big as the traditional lamp belt advantage. With the maturity of the technology and the improvement of the supporting industry chain can exist in the lighting industry, after all, COB lamp belt development time is still very short;
With the popularity of the design concept of "mainlightless lighting", LED linear strip products are becoming more and more popular in home decoration and full-house custom projects. Because of the continuous phosphor glue coating, COB LED strips can produce uniform light without very obvious individual points of light, so they can produce uniform and consistent light without the need for additional plastic cover. If you still need to use aluminum groove, you can choose very thin flat aluminum profiles.
