Description

Product Introduction

◎Self-cleaning function: Realizes rainwater self-rinsing and anti-oil adhesion through a superhydrophobic nano-coating, combined with an electrostatic dust removal system to actively purify PM2.5. It also adopts self-healing coating technology to ensure long-term weather resistance. Compared with IP54, the IP65 protection rating significantly improves dustproof, waterproof performance and reliability.

◎Advanced heat sink: The bionic shark gill structure enhances convective heat dissipation, the microchannel flat heat pipe achieves efficient temperature uniformity, and the intelligent temperature-controlled fan actively assists in heat dissipation in extreme environments. This triple design ensures that the temperature difference of the LED substrate is ≤2℃ under 1000W power, with noise as low as 52dB(A).

◎High color rendering light source: The full-spectrum LED chip improves the proportion of red light through phosphor optimization. The aspheric lens + microprism array achieves an illuminance uniformity of 0.8. Combined with anti-sulfurization technology and low thermal resistance packaging, it ensures that the light decay is ≤20% after 100,000 hours and CRI≥80.

Self-Cleaning Function

1.Superhydrophobic Nano-Coating

The surface of the lampshade adopts Evonik Degussa P84® polyimide nanomaterials, forming a micro-nano-scale rough structure (surface roughness Ra≤50nm) on the glass surface through a sol-gel process. This structure enables the water contact angle to reach 162° (static contact angle test, GB/T 30693-2014 standard).

◎Rainwater self-rinsing: When the rainfall intensity is ≥1mm/min, water droplets roll on the lampshade surface at a speed of 0.3m/s, carrying dust particles (particle size ≥5μm) to slide off quickly. The cleaning efficiency is 80% higher than that of ordinary glass.

◎Anti-oil adhesion: Through fluorination treatment (C4F8 plasma modification), the surface energy is reduced to 18mN/m, making it difficult for organic pollutants such as oil fumes and insect glue to adhere. Even in scenarios such as catering areas and industrial zones, the light transmittance can remain ≥92% (initial transmittance 95%).

2.Electrostatic Dust Removal Auxiliary System: Active Purification for PM2.5

To address tiny particles (particle size 0.1-2.5μm) such as sandstorms and industrial dust, a high-voltage electrostatic generator (output voltage ±8kV) is integrated inside the lampshade:

◎Corona discharge principle: Corona is generated through a tungsten steel needle electrode, ionizing surrounding air molecules to form a charged ion cloud. When PM2.5 particles pass through, they are given a positive charge and adsorbed on the negatively charged dust collection plate (aluminum substrate + titanium dioxide coating).

◎Intelligent start-stop control: The ambient concentration is monitored in real-time by a PM2.5 sensor (range 0-999μg/m³). It automatically starts when the value exceeds 75μg/m³ (critical value of WHO air quality standards), with a daily operation time ≤2 hours and energy consumption accounting for only 0.5% of the system's total power.

Advanced Heat Sink

1.Microchannel Flat Heat Pipe: The "Invisible Conduit" for Improved Temperature Uniformity

A copper-water microchannel heat pipe (thickness 3mm) is embedded between the LED substrate and the heat sink:

◎Phase change heat transfer mechanism: The vacuum degree inside the heat pipe is ≤1.3Pa. The working medium (deionized water) absorbs heat and vaporizes in the evaporation section (contact surface with the LED substrate), releases heat and liquefies in the condensation section (contact surface with the heat sink), and flows back through the capillary core (copper powder sintered body, porosity 75%) to form a cycle.

◎Temperature uniformity optimization: Test data shows that under 1000W full power operation, the temperature difference on the LED substrate surface is ≤2℃ (traditional aluminum substrate has a temperature difference ≥15℃), effectively avoiding accelerated light decay caused by local overheating.

2.Intelligent Temperature-Controlled Fan: Active Heat Dissipation Guarantee in Extreme Environments

Equipped with a dual-ball bearing DC fan (diameter 120mm, adjustable speed 500-2000RPM):

◎PWM speed control: The temperature of the heat sink is monitored in real-time by an NTC thermistor (resistance 10kΩ±1%@25℃). The fan starts when the temperature exceeds 60℃, and the speed has a linear relationship with the temperature difference (500RPM at ΔT=5℃, 2000RPM at ΔT=30℃).

◎Low-noise design: Sawtooth trailing edge blades (tooth height 2mm, quantity 16) are used to reduce aerodynamic noise from 65dB(A) to 52dB(A) (measured at 1m distance), meeting the requirements for nighttime use in urban residential areas.
