**Title: High-Quality DOB LED Flood Light Manufacturing Process at Ningbo Sunshinelux Lighting Co., Ltd.**
As a leading **LED flood light manufacturer** and **LED flood light factory**, Ningbo Sunshinelux Lighting Co., Ltd. specializes in producing cutting-edge lighting solutions, including **solar LED flood lights** and advanced **DOB (Driver-on-Board) LED flood lights**. This article delves into our meticulous production process, innovative technologies, and quality control systems that set us apart in the global lighting industry.

**1. Introduction to DOB LED Flood Light Technology**
DOB (Driver-on-Board) technology integrates the LED driver directly onto the circuit board, eliminating the need for external drivers. This design enhances energy efficiency, reduces failure rates, and allows for slimmer, more durable fixtures—ideal for industrial, commercial, and **solar LED flood light** applications.

**2. Material Selection & Component Sourcing**
**2.1 High-Performance LED Chips**
We source premium LED chips from trusted suppliers like CREE or Bridgelux, ensuring high luminous efficacy (up to 180 lm/W) and a lifespan exceeding 50,000 hours.
**2.2 Driver-on-Board Modules**
Our in-house designed DOB modules use constant current ICs and high-temperature-resistant components (rated for -40°C to 105°C), ensuring stable performance in harsh environments.
**2.3 Housing & Optics**
- **Aluminum Alloy Housing**: Die-cast aluminum (ADC12) with nano-ceramic coating provides IP67 waterproofing and corrosion resistance.
- **Tempered Glass Lens**: 92% light transmittance with anti-glare optics for uniform beam distribution (beam angles: 60°–120°).

**3. Production Process of DOB LED Flood Lights**
**3.1 SMT (Surface Mount Technology) Assembly**
- Automated pick-and-place machines mount LED chips, resistors, and DOB driver components onto aluminum PCBs.
- Reflow soldering ensures precise thermal profiles (peak temperature: 245°C) for strong solder joints.
**3.2 Thermal Management Design**
- **Heat Sink Fabrication**: CNC-machined aluminum fins increase surface area for optimal heat dissipation (thermal resistance <1.5°C/W).
- **Thermal Interface Materials**: High-thermal-conductivity silicone pads (5 W/m·K) bridge gaps between LEDs and heat sinks.
**3.3 Optical System Assembly**
- Lenses or reflectors are aligned using laser-guided systems to achieve accurate beam angles.
- Silicone gaskets and ultrasonic welding ensure airtight sealing (IP67/IP68).
**3.4 Smart Features Integration (Optional)**
For **solar LED flood lights**, we integrate:
- PWM solar charge controllers (MPPT efficiency >98%).
- Motion sensors or dusk-to-dawn controllers via Bluetooth/Wi-Fi modules.

**4. Rigorous Quality Control & Testing**
**4.1 Electrical Safety Tests**
- **Hi-Pot Test**: 3.75kV AC voltage applied for 1 minute to check insulation integrity.
- **Surge Protection**: Compliance with IEC 61000-4-5 (withstands 4kV surges).
**4.2 Photometric Testing**
- Goniophotometers measure luminous flux, beam angle, and color consistency (SDCM <3).
- 500-hour aging tests verify lumen maintenance (>90% at L70).
**4.3 Environmental Simulation**
- Temperature cycling (-40°C to +70°C) and salt spray tests (ASTM B117) validate durability.
- Vibration tests simulate transportation stresses (frequency: 10–55Hz; duration: 2 hours).
