Explosion-proof LED light fixtures are a kind of explosion-proof lamps, and they are also the most energy-saving explosion-proof lamps at present. They are widely used in oil fields, power plants, chemical plants, petroleum and other industries. So when you want to prolong the service life of explosion-proof lamps, what factors should you pay attention to?
In the manufacturing process of LED chips, the pollution of other impurity ions, lattice defects and other processes will affect its life, so the use of high-quality LED wicks is the first condition.
A reasonable design of explosion-proof LED lamps meets other indicators of the lamps, and a key issue is to dissipate the heat energy generated when the LED is lit.
However, for the integrated light source lamps (single 30W, 50W, 100W) sold in the market now, the heat dissipation of the light source and the heat dissipation channel of these products is not smooth. , Some products use low-power tubes of about 0.07W, because there is no reasonable heat dissipation mechanism, resulting in very fast light decay. Therefore, choosing a reasonable lamp design is a key factor for maintaining the life of explosion-proof LED light fixtures.
Whether the power supply of explosion-proof LED lamps is reasonable will also affect their life. Because LED is a current-driven device, if the power supply current fluctuates greatly, or the frequency of power supply spikes is high, it will affect the life of the LED light source. The life of the power supply itself mainly depends on whether the design of the power supply is reasonable. On the premise that the power supply is designed reasonably, the life of the power supply depends on the life of the components.
The short life of LED lamps is mainly due to the short life of the power supply, and the short life of the power supply is due to the short life of the electrolytic capacitor.
Another characteristic of the life index of electrolytic capacitors is that the life span must be stated at what degree of working ambient temperature, and it is usually specified as the life span at an ambient temperature of 105°C.
The lower the ambient temperature, the longer the service life of the capacitor. Even the most common electrolytic capacitor with a life span of 1,000 hours can reach 64,000 hours at an ambient temperature of 45°C, which is enough for ordinary LED lamps with a nominal value of 50,000 hours.
