There are many reasons why the 5050 lamp is easily dead. It is mainly affected by the chip, bracket, glue, gold wire and packaging technology.
1, chip
LED chip is a solid-state semiconductor device, it can directly convert electricity into light, it is the heart of LED lamp beads, it is equivalent to the car's engine, LED lamp beads antistatic index depends on the LED light-emitting chip itself, and The packaging material is expected to be basically unrelated to the packaging process, so the quality of the chip is critical.
Therefore, to produce a good 5050 lamp beads, you must use chips produced by major brand manufacturers. For example, ELiSTAR wafers, CREE Core, OSROM and other world-class brands such as Yuliang Optoelectronics are used, and the quality is guaranteed.
2, gold line
The gold wire has the advantages of large electrical conductivity, good thermal conductivity, corrosion resistance, good toughness, and excellent chemical stability, but the price of the gold wire is expensive, resulting in high packaging cost. In the periodic table of elements, the transition metal elements of the four metal elements of gold, silver, copper and aluminum have a higher conductivity.
Many LED manufacturers have tried to develop copper alloys, gold-clad silver alloy wires, and silver alloy wires instead of expensive gold wires. Although these alternatives are superior to the gold wire in certain characteristics, they are far less stable in terms of chemical stability. For example, silver and gold-clad silver alloy wires are susceptible to sulfur/chlorine/brominated corrosion, and copper wires are easily oxidized. In the case of encapsulated silicone similar to absorbent breathable sponges, these alternatives make the bond wire susceptible to chemical corrosion, the reliability of the light source is reduced, and the use time is long, and the LED lamp beads are easily broken and die.
Yuliang Optoelectronics uses a pure gold wire and is not susceptible to chemical corrosion. The 5050 lamp beads produced are durable and not easily dead.
3, bracket
At present, there are iron brackets and aluminum brackets on the market. Copper brackets are used at a slightly higher end, and Yu Liangguang adopts copper brackets. To prevent oxidation of copper, a silver layer is generally plated on the surface of the bracket and the thickness is uniform, which effectively solves the problem of electrical energy. loss.
4, glue, Yu Liang photoelectric imported glue, quality assurance.
The 5050 lamp beads produced by Yuliang Optoelectronics Co., Ltd. are of reliable quality and are deeply loved by customers. They are moisture-proof, anti-death light, anti-sulfurization, good heat dissipation, ultra-low light decay, and price advantage, because we are the only one of the Chinese mainland. One of the many strategic cooperation contractors, and has 10 years of experience in small and medium power packaging!
