Description

Product Advantages

◎Advantages of height adjustability: By dynamically adjusting the height of the lamp panel, it realizes the optimization of the light environment, the improvement of maintenance safety, the maximization of space utilization and the enhancement of wind resistance.

◎Features of stainless steel lamp panel: Adopting 316L stainless steel and electrolytic polishing process, it combines corrosion resistance, lightweight and efficient thermal management, significantly extending the service life of the equipment.

◎Breakthrough in IP65 protection: It achieves complete dustproof and low-pressure water column spray protection. Compared with IP54, it is comprehensively improved in dustproof, waterproof and reliability, and is suitable for extreme environments.

Height Adjustable System

1.Dynamic Optimization of Light Environment

◎Precise illuminance control: The height of the lamp panel can be adjusted with 0.1-meter precision within the range of 15-40 meters. Combined with the dimming function of the LED light source, it realizes stepless adjustment of ground illuminance from 50-500lx.

◎Light pollution prevention and control: By lowering the height of the lamp panel during non-operational hours at night, the beam divergence angle can be compressed from 120° to 90°, reducing light intrusion into surrounding residential areas.

◎Enhanced emergency lighting: In case of emergencies such as fire and power outage, the lamp panel can be quickly lowered to 10 meters, and combined with the emergency power supply, it realizes local high-brightness lighting (≥300lx), providing clear visual guidance for personnel evacuation.

2.Revolution in Maintenance Safety and Efficiency

◎Zero risk of aerial work: Traditional high mast lamp maintenance requires 4 people to complete 30-meter aerial work in 8 hours, while this system realizes one-key lifting of the lamp panel through the ground control terminal. Maintenance personnel always operate on the ground, and the working hours for a single maintenance are reduced to 2 people for 1.5 hours.

◎Integrated tool design: The lamp panel is equipped with standardized installation interfaces, which can quickly replace components such as LED modules and ballasts, reducing the types of tools by 70%.

◎Support for predictive maintenance: Built-in inclination sensors and vibration monitoring modules can track the structural deformation of the lamp panel during lifting in real time. When the verticality deviation exceeds 0.5°, it automatically alarms to prevent jamming failures caused by mechanical wear.

3.Maximization of Space Utilization

◎Multi-scenario function switching: In port container yards, the lamp panel can be raised to 40 meters during the day to achieve wide-area coverage (coverage radius ≥120 meters), and dynamically adjusted to 25-35 meters at night according to operation needs, focusing on lighting specific stacking areas to reduce energy waste.

◎Coordination with building structures: In urban square projects, the lamp pole can be designed as a retractable structure, shrinking to 20 meters during the day to avoid blocking the view of the landscape, and extending to 30 meters at night to provide basic lighting, achieving a balance between functionality and aesthetics.

◎Optimization of wind resistance: When the height of the lamp panel is reduced, the wind-receiving area of the overall structure is reduced by 40%-60%. Under the condition of a level 12 typhoon (wind speed 32.7m/s), the top displacement of the 30-meter high lamp pole is 55% smaller than that of the 40-meter one, significantly improving the stability of the equipment.

Stainless Steel Lamp Panel

Material Selection Standards

◎Main structure: Adopting 316L austenitic stainless steel with nickel content ≥12% and molybdenum content ≥2.5%. Compared with 304 stainless steel, the pitting resistance equivalent number (PREN) in chloride ion environment is increased by 40%, suitable for corrosive scenarios such as coastal areas and chemical industry.

◎Surface treatment: After electrolytic polishing, the surface roughness Ra ≤0.4μm, which reduces the dirt adhesion area by 30% compared with the conventional wire drawing process, and at the same time increases the reflectivity to more than 85%.

Thermal Management and Electrical Safety

◎Thermal conduction design: A 3mm thick aluminum-based heat dissipation plate is set on the back of the lamp panel, which is closely attached to the stainless steel frame through thermal conductive silicone grease, with thermal resistance ≤0.5℃/W, ensuring that the LED junction temperature ≤85℃.

◎Electrical isolation: Adopting a double-layer insulation structure, a 5mm air gap is set between the stainless steel shell and the electrical cavity, and the withstand voltage test reaches 5kV/1 minute without breakdown, in line with IEC 60598-1 safety standards.

◎Electromagnetic shielding: The grounding resistance of the lamp panel shell ≤0.1Ω, and the shielding effectiveness in the 10MHz-1GHz frequency band ≥60dB, effectively suppressing electromagnetic interference to surrounding equipment.
