LED explosion-proof lamp adopts reliable sealing design and surface spraying treatment, good waterproof performance, IP65 protection grade, waterproof and violent attack, excellent corrosion resistance, ensuring long-term outdoor sun and rain, wind Blowing rain hits long-term reliable work. LED explosion-proof lamp adopts reasonable light distribution design, with large illumination range, angle light, high brightness and uniform illumination.
The LED explosion-proof lamp has a high value for promotion and has the following advantages.
1. Suitable for places with high humidity, high protection requirements, corrosive explosive gases and non-conductive dust.
2. Applicable to Zone II and Zone 2 of IIAIIBIIC explosive gas mixture, temperature group T1-T6; Zone 20, Zone 21 and Zone 22 of non-conductive flammable dust environment. It is suitable for working lighting in hazardous areas such as oil exploitation, refining, chemical, shipbuilding, electric power, oil and gas platforms, oil tankers, etc.
Several factors affecting the life of LED explosion-proof lamps:
1, the quality of the die is decided
LED explosion-proof lamp
Primary condition of life
In the manufacturing process of LED chips, other impurity ion contamination, lattice defects and other processes will affect their life, so the use of high-quality LED die is the primary condition.
2. Whether the post-process package is reasonable will affect the life of the LED
Whether the post-process packaging of the LED is reasonable will affect the life of the LED. At present, the world's major companies such as Cree, Lumilends, Nichia and other high-level LED packages are protected. These companies have higher levels of post-process packaging requirements, and their LED life is guaranteed. However, most of the LED post-process packages of the enterprise are more imitation, and the shape and process quality are poor, which seriously affects the life of the LED.
3, lighting design is a key issue affecting the life of LED explosion-proof lamps
A reasonable luminaire design In addition to other indicators of the luminaire, a key issue is to dissipate the heat generated by the LED. Using high-quality LED originals from Cree and other companies on different luminaires, LED life can be several times or even dozens of times. For example, the integrated light source luminaires currently sold in the market (single 30 W, 50 W, 100 W), the light source and the heat dissipation channel contact parts of these products are not well cooled, and as a result, some products cause light after lighting for 1-3 months. More than 50% decay, some products use a small power tube of about 0.07 W, because there is no reasonable heat dissipation mechanism, resulting in very fast light decay. These products are low in technical content, low in cost and short in life.
4, the lamp power supply is critical to the life of the LED explosion-proof lamp
Whether the power supply of the luminaire is reasonable or not will also affect its life. Because the LED is a current-driven device, if the power supply current fluctuates greatly, or the power spike has a high frequency, it will affect the life of the LED light source. The life of the power supply itself depends mainly on whether the power supply design is reasonable. Under the premise of reasonable power supply design, the life of the power supply depends on the life of the components.
5, the ambient temperature is

Lifetime impact
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 they must describe the lifespan under the conditions of the working temperature, and are usually specified as the life at 105 °C ambient temperature. The lower the ambient temperature, the longer the capacitor life. Even the most common 1,000-hour electrolytic capacitor can reach 64,000 hours at an ambient temperature of 45 ° C. It is enough for a typical LED lamp nominally 50,000 hours. Used.
