Description

Product Introduction

◎The 400W LED parking lot light adopts 400-500 high-power LED chips, with a luminous flux of over 40,000lm. The optical design ensures uniform illuminance and anti-glare performance, with an IP65 protection rating, adapting to complex environments.

◎Intelligent interaction: High-end models integrate full-color LED screens, supporting dynamic information display, light sensing + human body induction, and remote control. Combined with IoT technology, they realize energy efficiency management and real-time data monitoring.

5,400 High-Density LED Beads

Core technological breakthroughs in bead design

◎Chip-level integration technology: Uses 5,400 0.5W high-color-rendering LED chips (size 2.0mm×2.0mm), and increases the bead density to 3 times the industry average through COB (Chip on Board) packaging technology. Measured data shows that its luminous efficiency reaches 160lm/W (traditional solutions are 110lm/W), outputting 64,000 lumens at 400W power, 45% brighter than traditional lamps;

◎Hexagonal honeycomb heat dissipation structure: The bead substrate uses aviation-grade aluminum, with hexagonal honeycomb heat dissipation grooves etched on the surface (depth 2mm, spacing 1.5mm), combined with graphene thermal pads (thermal conductivity 1,500W/m·K), keeping the bead junction temperature stable at ≤75℃ (traditional solutions have junction temperatures >95℃). After 3,000 hours of continuous operation in the high-temperature and high-humidity environment of Sanya, Hainan, the light decay is only 3% (traditional solutions have light decay >15%);

◎Intelligent zoned dimming: Divides 5,400 beads into 9 independently controlled zones, each zone achieving 0-100% brightness adjustment through an MCU chip. For example, when a vehicle enters, the central area of the lamp (covering the driveway) maintains 100% brightness, and the edge area (sidewalk) automatically drops to 50%, meeting safety needs while reducing energy consumption.

Industrial-Grade Intelligent LED Information Screen

Core technological breakthroughs of the information screen

◎Shared power supply and communication design

The information screen and lighting module share a 400W driver power supply, providing a stable 24V voltage for the screen through a DC-DC conversion circuit, saving 70% of cable costs and 85% of installation time compared with independent power supply solutions. It also adopts Power over Ethernet (PoE) technology, realizing power and data transmission through a single network cable (transmission distance 100 meters) to avoid wireless signal interference;

◎High-brightness adaptive display

The screen uses Mini-LED backlight technology (with 512 local dimming zones), with a peak brightness of 2,000nit (traditional electronic screens are 800nit), remaining clearly visible even in strong midday light. Measured data shows that its contrast ratio reaches 10,000:1 (traditional solutions are 3,000:1), and visibility in sunlight is increased by 300%;

◎Seamless docking with multiple systems

Supports real-time docking with Parking Management Systems (PMS), City Information Platforms (CIP), and Emergency Command Systems (ECS). For example, in the Shenzhen Futian CBD parking lot project, the lamp screen can synchronously display over 20 types of information such as parking space navigation, charging pile status, weather warnings, and government announcements, with an information update delay of <0.3 seconds.
