Independent Core Technology: Our core circuit board is produced by our own SMT automated production line, ensuring precise and consistent solder joints, thoroughly solving issues like dead lights and poor contacts caused by manual soldering.
Circuit Reliability Protection: The circuit board undergoes a three-proof coating process (moisture-proof, mildew-proof, salt-fog-proof), ensuring no short circuits or failures even in rainy or humid intersections.
Clear Anti-fake Brightness: Professional optical mask combined with black inner lining design effectively absorbs external strong light, ensuring clear on/off status even under direct sunlight without causing visual misjudgment.
Energy Saving & Long Lifespan: Compared to traditional lights, it saves more than 80% energy. The LED lifespan is up to 100,000 hours, significantly reducing municipal electricity costs and the frequency of replacement.
Easy Installation and Maintenance: Supports horizontal and vertical installation with 180° rotation, compatible with universal brackets; the shell has good sealing, making maintenance easy and shortening on-site construction time.
Strong Voltage Adaptability: The wide voltage power supply design ensures stable brightness even when there are voltage fluctuations or when powered by a generator, without flickering.
Core In-house Production: The circuit board is produced using our in-house SMT line, not outsourced, ensuring higher consistency.
Fast Delivery: With the scale advantages of a 100-acre manufacturing base, we can quickly respond to large-volume engineering orders.
High Compatibility: It can seamlessly interact with various standard traffic signal controllers, with simple installation.

Frequently Asked Questions (FAQ)

Q: What is the brightness standard for your 400mm signal light?
A: It uses 205 high-brightness LED beads with uniform light emission and strong penetration. Combined with a professional optical mask, it ensures clear visibility even 400 meters away, even in direct sunlight or heavy rain.

Q: Is the core circuit board purchased or made in-house?
A: It is entirely produced in-house using our own SMT automated line. Compared to outsourced assembly, we can more strictly control solder joint quality and component selection, reducing dead light rates from the source.

Q: Will it short-circuit in humid or rainy areas?
A: No. Our circuit boards are treated with a three-proof coating process for excellent moisture-proof, salt-fog-proof performance. The shell uses dual silicone rubber sealing rings, and the protection level has been tested to reach IP65.

Q: Will "false bright" phenomena occur under direct sunlight?
A: Our lights use an anti-mimic optical design combined with high-contrast inner linings that effectively absorb reflected light. Even in the midday sun, drivers can accurately distinguish the on/off status.

Q: What installation methods do you support? Are there any requirements for the bracket?
A: It uses a universal structure design that supports both horizontal and vertical installation, with a 180° adjustable angle. It is compatible with mainstream L-shaped and U-shaped signal light brackets on the market.

Q: Does your packaging ensure no damage during long-distance export shipping?
A: We use thick pearl cotton cushioning combined with high-strength five-layer corrugated cartons. For large-volume exports, we provide fumigation-free wooden pallets and fully enclosed shrink-wrap protection to ensure zero damage during sea or land transportation.

Q: If the grid voltage is unstable, will the lights flicker or get damaged?
A: No. The built-in wide voltage power supply (AC85-265V) maintains constant brightness even when there are significant voltage fluctuations, and it also has surge protection to safeguard the core circuit.
