Q: How to effectively extend the life of LED explosion-proof lights?

A:

The life of LED explosion-proof lamps is long, and the heat dissipation of light source and power supply is the key.

Using high boride glass lampshade, can withstand high energy impact, lamp beads use Purui chip imported from the United States, reduce light decay, more efficient energy saving and environmental protection

Carefully designed heat dissipation air guide groove with air reverse structure ensures the service life of LED light source

First of all, the quality of the die is the primary condition for determining the life of the LED explosion-proof lamp. During the manufacturing process of the LED chip, the pollution of other impurity ions, lattice defects and other processes will affect its life. Therefore, the use of high-quality LED die is the primary condition. , Songbei Explosion-proof uses the American Corey and Purui chips to better ensure the life of LED explosion-proof lamps.

The second is the process packaging. Whether the post-process packaging of the LED is reasonable will affect the life of the LED. At present, several major global companies such as Cree, Lumilends, Nichia and other high-level LED packaging have patent protection. These companies have relatively high post-process packaging requirements, and their LED life is guaranteed. However, most of the LED post-process packaging imitations of most companies are ok from the appearance, but the process structure and process quality are poor, which seriously affects the life of the LED.

Then, the design of lamps is also a key issue of the life of LED explosion-proof lamps. In addition to satisfying other indicators of lamps, a key problem is to dissipate the heat energy generated when the LEDs are lit. If the high-quality original LED products of Cree and other companies are used in different lamps, the LED lifespan can vary several times or even dozens of times.

Finally, the power supply has a great influence on the life of the LED explosion-proof lamp, and whether the power supply of the lamp is reasonable will also affect its 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 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.

The explosion-proof explosion-proof lamp produced by Songbei Explosion-proof Electrical Appliances is made of aluminum alloy die-casting with high strength; the surface is high-voltage electrostatic spraying, which has strong corrosion resistance and light structure. Suitable for various installation methods.
