I wonder if you have ever had this experience: after a thunderstorm, the TV at home suddenly went black! Even the smart door locks will fail to sense. These seemingly insignificant faults are likely to be caused by lightning surges.

What is a lightning surge? Many people may be confused. In fact, in outdoor lighting scenes, lightning surges are a common natural phenomenon. It is no exaggeration to say that lightning surges seriously threaten the street light LED driver power supply and lighting system. Under the influence of lightning surges, the entire lighting system may "collectively go off work"!

What is a lightning surge?

Lightning surge, also known as lightning surge or surge, refers to a large-amplitude, short-term voltage or current pulse that occurs instantly on power, telecommunications or signal transmission lines due to lightning activity or other transient high-power events.

Characteristics of lightning surge

Suddenness: Lightning surge occurs in a very short period of time (milliseconds to microseconds), and the specific manifestation of lightning surge is a sharp rise in voltage or current.

High intensity: The amplitude of the surge far exceeds the normal operating voltage or current level. The voltage surge can reach thousands or even tens of thousands of volts, and the current surge can reach hundreds or even thousands of amperes.

Transient: The surge lasts for a short time, after which the voltage or current will quickly drop back to normal levels.

Destructive: The energy of lightning surge is huge, which may cause insulation breakdown of electrical equipment, damage to semiconductor devices, data loss, control system failure, and even fire.

Impact of lightning surge on lighting

Direct damage to lamps

Lightning surge is a transient high voltage and high current impact that may directly damage the electronic components of LED lamps such as drivers and LED modules, causing the lamps to burn out instantly or performance degradation.

Impact on the stability of the lighting system

Lightning surge may interfere with the circuit of the lighting system through electromagnetic pulses, causing the lamps to flicker, short-circuit or program errors, affecting the normal operation of the lighting system.

Grid voltage fluctuations.

Thunderstorms may cause short-term voltage instability in the regional power grid, causing lamps to flicker.

How can LED driver power prevent lightning surges?

Suretron/SCPOWER has 15 years of rich experience in the LED driver power segment, paying special attention to the reliability design and protection details of dimming power supplies, and strictly abides by the relevant national design standards (GB/T 17626.5, which is equivalent to IEC-61000-4-5, and stipulates that the differential mode withstand voltage is 2KV and the common mode withstand voltage is 4KV.

Suretron/SCPOWER LED driver power supplies basically all meet the standards of differential mode withstand voltage 2KV and common mode withstand voltage 4KV. The lightning protection design of most driver power supplies is higher than the relevant national standards, with differential mode withstand voltage at 4KV and common mode withstand voltage at 6KV.

Suretron/SCPOWER constant current high-power dimming power supply with lightning surge protection.

In order to adapt to more complex outdoor application environments, the lightning protection design of Suretron/SCPOWER constant current high-power driver power supply has a differential mode withstand voltage of 6KV and a common mode withstand voltage of 10KV. The high-standard lightning protection design can not only effectively absorb lightning surges, but also effectively absorb lightning surges. The lightning surge can not only save the energy of the LED lamps, but also ensure the stable operation of the lamps under extreme weather conditions.

Lightning surge is a natural phenomenon that cannot be avoided or ignored in outdoor application environments. However, through scientific protection design and reasonable maintenance measures, we can effectively reduce the impact of lightning surge on LED lamps and lighting systems, and ensure that the driving power supply and lamps and other lighting equipment can operate stably under extreme weather conditions.

With the continuous upgrading of technology, the lighting industry's lightning surge protection measures are also continuously upgraded. In the future, Suretron/SCPOWER will continue to focus on the research and development of higher-performance LED driving power supplies, and provide more reliable lighting support for outdoor lighting through technological innovation and optimized design.
