I believe you have noticed that when we use resin luminous characters for a period of time, we will find that some luminous characters will darken. So what are the factors that make resin luminous characters darken? Let's analyze them.
1. Transformer short-circuit, transformer short-circuit is one of the reasons for the luminous word darkening, resulting in insufficient power supply. Need to check the transformer to find out the leakage part to solve.
2. The module lamp wire is broken, causing a short circuit.
3. The voltage of transformer and lamp bead does not match, so the matching transformer needs to be replaced.
4. The power supply is not in proportion to the w number of lamp beads, which is too small, resulting in insufficient power supply. Generally, the main reason for this situation in the later stage is whether there are multiple power supplies, and the power supply is damaged, resulting in insufficient power supply.
5. Some manufacturers blindly pursue low price to improve their price competitiveness, and use some low price, inferior and unqualified lamp bead modules. Some illegal manufacturers use recycled led core module. The lamp bead often increases the current to make it have the same brightness as the standard lamp bead. However, the service life of the lamp bead is generally less than half a year about.
6. The anti yellowing quality of resin AB glue is not up to standard. Of course, as long as there is no problem of resin glue yellowing, it has little effect. If the yellowing is serious, change the glue immediately.
In fact, there are many reasons leading to LED product light decay, the key is the heat problem. Although many manufacturers do not pay special attention to heat dissipation in secondary products, the light decay degree of these secondary LED products will be higher than that of LED products that pay attention to heat dissipation under long-term use. The thermal resistance of LED chip itself, the influence of silver glue, the heat dissipation effect of substrate, colloid and gold wire are also related to light decay.
The specific reasons still need to be analyzed, so that we can better take the seat according to the number, fundamentally solve the problem, pay more attention to our official website, or contact us at any time.
