LED explosion-proof lights are widely used in petrochemicals, coal mines, power plants, gas stations, and other places. The LED explosion-proof lamp has a good energy-saving effect and good brightness. So what affects the life of the LED explosion proof lamp, and how can maintenance maximize the benefits?
What affects the life of LED explosion proof lights
1. Chip quality
In the manufacturing process of LED chips, other impurity ion pollution, lattice defects, and other technological processes will affect their life.
2. Post-process packaging
Whether the process packaging of the LED lamp is reasonable will affect the life of the LED. Experienced companies have patent protection for LED packaging. These companies have relatively high requirements for post-process packaging, and the life of their LEDs is guaranteed. Some small companies have more imitations of LED post-process packaging, and the quality is okay from the appearance, but in fact, their process structure and process quality are poor, which seriously affects the life of the LED.
3. Lamp power supply
Whether the power supply of the lamp is reasonable will also affect its life. Large fluctuations in power supply current or high frequency of power spikes will affect the life of the LED light source. The design of the power supply is reasonable, the components of the power supply are selected well, and the life of the LED explosion-proof lamp will be relatively increased.
4. Lamp design
The key to a reasonable luminaire design is to dissipate the heat generated when the LED is lit. Using the same LED chip, but the design structure of the LED lamp is different, the life of the LED lamp can be several times or even dozens of times different. For example, after some products use low-power chips of about 0.07 W, the light decays very quickly due to the lack of a reasonable heat dissipation mechanism. There are also some integrated light source lamps (single 30 W, 50 W, 100 W). The light source of these products does not dissipate smoothly at the contact part of the heat dissipation channel. As a result, some products cause light attenuation of more than 50% after being lit for a few months. Therefore, when purchasing an LED explosion-proof lamp, you must choose an experienced manufacturer to do it.
5. Ambient temperature
The current 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. The life of an electrolytic capacitor must be stated at the working environment temperature of how many degrees it is. Basically, it is specified as an ambient temperature of 105°C. The lower the ambient temperature, the longer the service life of the capacitor. Under normal circumstances, it is sufficient for ordinary LED lamps with a nominal rating of 50,000 hours.

Daily maintenance of LED explosion proof lights
High-quality LED explosion-proof lamps can be used for three or four years, but if you don’t pay attention to the maintenance of LED explosion-proof lamps, they can only be used for two years, which is equivalent to spending more money, so how to extend the life of LED explosion-proof lamps Woolen cloth?
1. Regularly clean up the dust and debris on the lamps to ensure that the LED explosion-proof lamp has a good heat dissipation effect (if not cleaned for a long time, the dust adheres to the lamps and blocks the heat emitted by the lamps, causing the heat to not be dissipated). Good heat dissipation To extend the life of the LED lamp.
2. Try not to work the lamps uninterruptedly, because the temperature of the lamps will gradually heat up during uninterrupted work. The higher the temperature, the shorter the life of the lamps.
3. Regularly check the voltage of the line. If the voltage is unstable, the line must be maintained and overhauled.
4. When the LED explosion-proof lamps work in an environment higher than 60 degrees for a long time, the lamp life will be reduced by about two-thirds. Therefore, the ambient temperature of the LED explosion-proof lamp should not be higher than 60 degrees as far as possible.
