Ubufakazi bokuqhuma kwe-Shenhai
Ngemva kokuthenga kubakhiqizi bokukhanya okungaqhumisi kwe-LED, kukhona ukucatshangelwa okuningana kokusebenza ukuze kuqinisekiswe ukuphepha nokuzinza ngesikhathi sokusetshenziswa.
1. Izinga lokushisa:
Qaphela ukunyuka kwezinga lokushisa, njengoba ukukhuphuka kwezinga lokushisa elingaphandle kunganciphisa ukumelana kwangaphakathi komthombo wokukhanya we-LED. Uma inikwa amandla umthombo ozinzile we-voltage, this can cause an increase in working current. If it exceeds the rated working current, it can affect the lifespan of the LED explosion-proof light, and in severe cases, “shisa ngaphandle” the light source. Ngakho-ke, it’s best to use a constant current source to ensure that the working current of the LED explosion-proof light is not affected by external temperatures.
2. DC Power Supply:
LED explosion-proof lights should be powered by a direct current source. Unlike explosion-proof searchlights and flashlights, some manufacturers use a “resistance-capacitance reduction” method to power LED products to reduce costs, which can directly impact the lifespan of the LED product. Using a dedicated switching power supply (preferably a constant current source) will not affect the product’s lifespan, though the cost may be relatively higher.
3. Sealing:
If LED explosion-proof lights are used outdoors, they face challenges with ungangeni manzi and moisture-proof sealing. Poor handling can directly impact the product’s lifespan. Some high-quality manufacturers use traditional epoxy resin “potting” methods to seal LED products. While effective, this method can be cumbersome for larger LED products, unsuitable for some applications, and may increase the product’s weight.
4. Anti-static Measures:
During the manufacturing process of LED explosion-proof lights, the same processing methods as explosion-proof flashlights should be used to implement anti-static measures. Ngokwesibonelo, workbenches should be grounded, workers should wear anti-static clothing, rings, and gloves, and if possible, install anti-static ion fans. Ukwengeza, maintaining workshop humidity around 65% is essential to prevent static electricity, especially since green LEDs are more susceptible to static electricity, electric fields, and currents, which are physical quantities produced by the presence or movement of electrical charges.
