LED outdoor street lamp is an efficient, energy-saving and environment-friendly lighting equipment with waterproof function. Generally speaking, the waterproof rating of LED outdoor street lamps is above IP65, which can effectively prevent the external substances such as rain and dust from eroding the lamps and ensure their normal work.

The service life of LED outdoor street lamps is generally determined by their quality, design and use environment. Generally speaking, high-quality LED outdoor street lamps can reach a service life of more than 50,000 hours, or even longer. This means that under normal use, an LED outdoor street lamp can work continuously for more than 5 years, which greatly reduces the frequency of replacing lamps and maintenance costs.

LED outdoor street lamps have a long service life, mainly for the following reasons:

1.Long service life of LED light source: LED light source adopts solid-state light-emitting technology, and has long service life without wearing parts such as filament and glass. Generally speaking, the life of LED light sources can reach more than 50,000 hours, or even longer.

2. Good heat dissipation design: LED outdoor street lamps usually adopt aluminum alloy shell, with good heat dissipation design, which can effectively dissipate heat, maintain the normal working temperature of lamps and prolong the service life of LED light sources.

3. Reliable power supply quality: High-quality LED outdoor street lamps use high-quality power supply, which has the functions of over-current, over-voltage and over-temperature protection, ensuring the normal work of lamps and prolonging their service life.

4. Good seismic performance: LED outdoor street lamps usually need to withstand various harsh climatic and environmental conditions, such as wind and rain, vibration and so on. High-quality LED outdoor street lamps have good seismic performance, can work normally in harsh environment, and prolong service life.

Generally speaking, LED outdoor street lamps have waterproof function and long service life. This makes LED outdoor street lamp an ideal lighting choice, which can provide efficient, energy-saving and reliable lighting effect in outdoor environment. With the continuous development and maturity of LED technology, the service life of LED outdoor street lamps is expected to be further extended, providing better solutions for urban lighting projects.
