LED 2835 Vs 5730 SMD Chip Difference

LED 2835 vs 5730 SMD Chip Difference. LED 2835 vs 5730 SMD Chip Difference. Do you know what the difference is between 0.5w 2835 smd leds and 0.5w 5730 smd leds? Both of them has the same input with 3-3.4vdc 150mA.

2835 lamp beads, 5050 lamp beads, 5730 lamp beads are a kind of packaging form of light-emitting diodes, SMD packaging structure, good heat dissipation performance, high light output efficiency of the lamp beads, high temperature resistant PPA and PCT bracket structure manufacturing, production is fully automated Solid crystal bonding wire dispensing and spectroscopic taping process, high production capacity and high cost performance are the main lamp bead types selected for LED finished lamps. They are widely used in fluorescent tubes, bulb lamps, ceiling lamps, floodlights and other indoor and outdoor lamps.

Through years of process improvement and quality improvement, the production capacity of LED packaging factories has been continuously released, and the types of products are also diverse. There are also some questions about the choice of packaging products for application-side customer engineers. Today, I will share with you the understanding of different packaged lamp beads. Advantages and disadvantages, provide engineers for reference.

Heat Dissipation Difference:

The 2835 lamp bead adopts a thermal separation structure, the chip and a PAD of the bracket are fixed together, and the electrode is a wire bonding position. The bracket PAD and the chip are directly in contact with the PCB board after bonding through the primer, so that the heat of the bracket is directly The chip passes through the primer to the PCB substrate, and the heat conduction speed is fast. The 5050 bracket has a plastic wrap on the back. The bracket is divided into three pads. The solder feet are surrounded by the plastic through a bending process and then bent to the bottom. The heat conduction method is the chip Go to the bottom of the bracket and then lead to the outside and PCB solder feet through the solder feet. The heat conduction method is slow and the thermal resistance is high. The 5730 bracket structure is different from the previous two. The middle pad is then punched to punch one pad. Cup shape, because the 5730 bracket has a long length, more plastic is needed to cover the pads, so the punched cup shape should not be too large. After the chip is fixed, the pads are directly in contact with the PCB board, but due to the small heat dissipation area, the heat dissipation is slower than 2835 Some, but much faster heat dissipation than 5050.

Package Dimension difference:

The naming of the above lamp beads is based on the outer length and width of the bracket. As the name suggests, the lamp bead model can be clearly distinguished from the outer length and width. For example, the size of the 2835 lamp bead is: 2.8*3.5*0.8mm

Bracket material

The plastics used by different lamp beads are different. At present, there are many types of domestic conventional PPA, and there are other materials such as PCT plastic, EMC, SMC, ceramics, etc.; why are there different plastic choices? This has a lot to do with the client’s outstanding demand for the performance of the lamp beads. Different plastics have different physical properties, so different plastics are produced. At the same time, the encapsulation glue is also a key factor in determining the physical properties of plastics.

Application

5730 SMD lamp beads have high white lumen, stable performance, good color consistency, and high cost performance; it is suitable for various LED lighting products. Widely used in LED tubes, LED bulbs, outdoor billboards, electronic displays, traffic lights, sign boards, car tail lights, LED light-emitting modules, LCD backlights, LED lighting, LED flexible light bars.
