Product
SMD, COB and CSP are three forms of LED light strips, among which SMD is the most traditional. Lanjing has always been committed to pursuing the ultimate chip and the refinement of light strip products, from 5050 lamp beads to today's CSP technology. There are endless types of light strip products on the market. Faced with a wide range of products, how to make trade-offs and choices? This is a question worth pondering.
At present, SMD and COB are widely used, each with its own advantages and disadvantages and different application scenarios. SMD is the most common and available in a variety of sizes; COB is favored by the market for its superior linear effect; and the birth of the new light strip CSP leads the new trend of the industry due to its more advanced chip packaging technology. So compared with traditional light strips COB and SMD light strips, what are the advantages of CSP light strips? Today, let Lanjing take you to learn together!
01
CSP leading packaging process
LED chips, also known as LED light-emitting chips, are the core components of LED soft strips and will directly affect the light quality of LED soft strips. How to break through the technical difficulties of packaging chips is a technical barrier that major manufacturers are working hard to break through.
The traditional packaging technology used by COB and CSP has complex structure, multiple and cumbersome processes, complex structure, time-consuming and labor-intensive, and high production costs. The illumination of the manufactured LED will be reduced due to the deterioration of the packaging material due to heat and other reasons, and the heat dissipation effect is not good, and the product stability is also poor.
After technological advancement, CSP chips use "flip chip and chip-level technology", with low thermal resistance and high electrical stability. Its volume is getting smaller and smaller, and its performance is more stable. The cost of CSP packaging is much lower than that of traditional packaging technology, which can save labor costs and packaging costs to the greatest extent, and has a high cost performance.
02
High light color accuracy
The traditional COB uses a dot powder process, the mixed light color is impure, and the color is not easy to control when mixing light. Good color consistency can only be achieved by sacrificing the yield rate.
The CSP lamp beads are arranged more densely, and the light is split before packaging, and the light emitting angle is larger. The light color accuracy of CSP is relatively high. In terms of mixed light color consistency, CSP has obvious advantages over traditional COB. This high-precision light color enables CSP light strips to provide more uniform and natural light in various lighting scenarios.
03
Super Flexibility
COB and SMD have average flexibility. If improperly handled, COB will have its package fall off, and SMD may cause the bracket of the lamp bead to break.
CSP uses glue to protect the lamp bead because it has no fragile links such as brackets and gold wires, which is safe and reliable. The chip is smaller in size, can be made thinner and lighter, has a small bending angle, and has stronger flexibility. This flexibility makes CSP light strips more flexible during installation and can adapt to various complex and narrow spaces.

Application scenario suggestions for the three products
In terms of application scenarios, the three light strips are widely used without obvious restrictions. Based on the respective advantages of the three products, Blue View has made a more detailed division of their usage scenarios:
SMD light strips are widely used because of their various sizes. They are more suitable for indoor edging, and waterproof products can also be used for outdoor contouring. Its flexibility and diversity make it an ideal choice for various interior decorations.
COB light strips have excellent linear effects and are better used in decorative lighting and prop display stand lighting. Its excellent linear effect can add a unique visual effect to the display space and enhance the display effect.
CSP light strips have a certain linear effect and are the most flexible and bendable. In addition, the light is split before packaging, and the yield rate and light color accuracy are better than the previous two light strips, which is relatively the most cost-effective. Therefore, in general, it has certain advantages in various indoor and outdoor applications. And its compact size has more obvious advantages in narrow space applications. Whether in commercial space or home environment, CSP light strips can provide beautiful and practical lighting solutions.
