Solution Provider: Aosay Lighting

Executive Summary

The client is an experienced and professional landscape lighting contractor based in Switzerland, focusing on large-scale municipal and real estate outdoor lighting projects. With extremely strict industry standards for outdoor and underwater lighting products, the client raised high requirements for PCB waterproof performance, color rendering consistency, and batch stability for its new-generation underwater landscape lamps. Aosay Lighting provided fully customized RGBW lamp PCB solutions, optimizing lamp bead arrangement, 24V low-voltage driving, synchronous dimming system and waterproof sealing structure through repeated technical communication. Rapid sample delivery and full compliance with professional testing standards helped the client achieve efficient product iteration, establishing a long-term stable full-product supporting partnership.

The Challenge: High Standard Landscape Lighting PCB Customization

Engaged in high-end European municipal and real estate landscape lighting projects for years, the client has rigorous and stringent product screening criteria. In the development of new underwater landscape lamps, the core difficulties and customized demands are as follows:

• Ultra-high Waterproof Reliability: Underwater working scenario requires PCBs to possess excellent waterproof and moisture-proof performance, adapting to long-term underwater operation and complex outdoor environments.
• Accurate Color Restoration & Batch Consistency: Landscape lighting puts forward strict requirements on RGBW color rendering effect, needing zero color difference and stable optical performance in mass production batches.
• Stable & Safe Driving Performance: The product needs to adopt 24V safe driving scheme, matching synchronous dimming function to realize uniform and smooth light color switching.
• High Assembly Compatibility: The PCB board structure must perfectly match the customer's lamp shell without secondary processing, ensuring high production and assembly efficiency.

The Aosay Lighting Solution: Custom RGBW PCB Optimization

In response to the client's high-standard requirements for underwater landscape lighting PCBs, our technical team conducted in-depth docking with the client's R&D department, iteratively optimizing every core parameter and structural detail to launch a targeted customized solution.

1. Optimized Lamp Bead Layout & Optical Design

According to the client's new lamp optical path design and lighting effect expectations, we adjusted the precise arrangement of RGBW lamp beads. The optimized layout realizes uniform light emission, eliminates local dark areas and astigmatism problems, and ensures highly consistent color restoration of each lamp, meeting the high-precision color matching requirements of high-end landscape lighting projects.

2. 24V Low-Voltage Drive & Synchronous Dimming System

To adapt to European outdoor electrical safety standards, we adopted a mature 24V low-voltage driving solution for the PCB. Combined with customized synchronous dimming circuit design, it supports stable and synchronous color switching and brightness adjustment of multiple lamps, with no stroboscopic, delay or color deviation during operation, perfectly fitting the dynamic lighting demands of landscape scenes.

3. Professional Waterproof & Sealing Structural Design

Aiming at the long-term underwater working environment, we optimized the PCB circuit layout and edge sealing structure. Cooperated with professional waterproof processing technology, the board achieves excellent waterproof, dustproof and corrosion resistance, effectively solving the failure risks of circuit dampness and short circuit in underwater scenarios, and greatly improving the product service life and operational stability.

4. Perfect Shell Adaptation & Zero Secondary Processing

Based on the client's original lamp shell size and structural parameters, we customized the PCB board size, hole position and overall structure with high precision. The finished PCB can be directly assembled with the client's shell without any cutting, drilling or modification, greatly simplifying the production process and improving the client's mass assembly efficiency.

Project Implementation & Testing Verification

After multiple rounds of technical confirmation and scheme iteration, Aosay Lighting completed rapid sample production and delivery. The client conducted comprehensive professional tests in its independent laboratory, covering dimensional tolerance detection, electrical performance test, RGBW color consistency verification and waterproof stability test. All test indicators fully meet European industry standards and the client's customized requirements, with zero unqualified items.
