Lightning protection measures for solar street lights and installation of high pole lights

The main difference between the lightning protection work of solar street lights and conventional street lights lies in the fact that the response speed of LEDs is faster than that of conventional street lights, but their voltage tolerance capacity is smaller.

Lightning protection devices are primarily designed based on the power supply voltage. During thunderstorm weather, the LED street light circuit may experience a sudden peak voltage or peak current due to electrostatic or electromagnetic induction, which can impact and damage the LED street light equipment.

In regions prone to open spaces, high mountains, and thunderstorms, lightning protection measures are particularly important. So, what aspects should be considered?

1.Grounding for solar street lights: This is crucial, using the pole body as a grounding device is sufficient. The grounding grid should be determined based on the geological soil conditions, with a grounding resistance of less than 10 ohms. Therefore, it is necessary to select suitable LED-specific surge protectors to protect the power line from overvoltage surges and prevent widespread LED street light damage from lightning strikes in the same area.

2.Circuit: Install dedicated photovoltaic DC surge protectors.

3.Protection against direct lightning strikes: Use the pole body as a lightning rod. In thunderstorm weather, which often occurs, how to effectively protect solar street lights from lightning strikes is a challenging technical issue that many solar street light manufacturers face and must address.

Following the traditional approach, the use of solar energy is becoming increasingly widespread, especially in recent years as solar lighting has become a popular industry. To meet the safety and convenience needs of people traveling at night in various regions, the promotion of urban and rural road lighting projects is being vigorously pursued. When it comes to the construction of lighting projects, how do we choose suitable rural solar street lights for our lighting needs, and what should be paid attention to in the configuration of solar street light systems?

For the solar street lights currently being promoted and used, their system configuration has high requirements. If the configuration is not suitable, issues such as lack of outdoor solar street lighting during rainy weather, battery life, etc., may arise. However, if the system configuration is reasonable, these issues can be quickly resolved.

The controller is the smallest component of the solar street light system, invisible yet crucial. The quality of the controller directly affects the aging of the solar street light system components, which is why even small details have a significant impact. Additionally, attention should be paid to the waterproofing of the 3-meter solar street light battery and the conversion rate of the solar panel.

The installation of high pole lights not only meets people’s leisure and entertainment needs but also serves as an important landscape element. High pole light installations are indicative of the level of civilization in a unit, a city, or even a country. External nighttime lighting uses light to shape the nighttime image of buildings, showcasing their unique artistic charm, cultural significance, and architectural features.

It is important to choose appropriate façade lighting methods, control the lighting area, reduce electricity consumption, address illumination, light color, color rendering, three-dimensionality, texture, glare, and other requirements. Emphasis should be placed on spatial clarity, eliminating unnecessary shadows, controlling the adverse effects of heat and ultraviolet radiation on humans and objects, creating suitable brightness distribution and illumination levels, limiting glare, reducing discomfort, and effectively utilizing natural light.

Requirements for lamp posts: The top of a telescopic high pole light should have lightning rods, rain covers, a pulley assembly distributed at 60 degrees, and a hook system distributed at 120 degrees.

Rain covers prevent water from entering the interior of the lamp post, protecting components such as pulleys from rust due to rain exposure. The pulley assembly prevents wire ropes and cables from dislodging or entangling, while the design of the hook system ensures that the hooks automatically flip when the lamp plate descends, allowing for safe and reliable unloading of the wire rope after completion of the lifting operation, thus extending the lifespan of the wire rope.

The rectangular cavity at the bottom of the telescopic high pole light houses the electrical control system and the lifting system components, including electric motors. The electrical control system is installed inside the lamp post to prevent faults in the lifting movement due to harsh outdoor conditions.

The electrical control system includes various circuit overload protection devices, and the conductors in the system are widely made of copper-based silver plating to ensure good electrical contact.
