Melhorando a confiabilidade da iluminação pública externa: inovação à prova d'água e de processo do receptáculo de 3 pinos da série JL200
Introduzir
Urban infrastructure depends heavily on reliable street lighting. Rain, humidity, and extreme temperatures can damage their parts. Over time, these conditions make them weak.
That’s why companies like Long-Join keep pushing boundaries. They find new ways to control light. The JL200 Series 3pin receptacle is a standout example. Developed with end-user feedback and field experience, this product addresses long-standing issues in street lighting systems—especially in waterproofing and long-term durability.

What Are the Standout Features of the JL200 Series 3pin Receptacle?
Outdoor lights do more than turn on at night. They boost safety and style. Today, it’s about using energy wisely. It’s also about performance that lasts and smooth integration. Street lighting infrastructure has evolved—and so have the expectations for components like the photocell receptacle. That’s where the JL200 comes in.
Lighting control systems must stand up to tough conditions. They should also be smart and easy to connect with other devices. The JL200 Series has a 3-pin receptacle. We designed it to meet those expectations. Its core features include:
Recurso | Beneficiar |
3pin Standard Interface | Compatible with most light photocell sensors and street light controllers |
Full Glue Process | Enhanced waterproofing and vibration resistance |
Fully Covered Metal Sheets | Improved grounding and corrosion resistance |
NEMA Compatibility | Seamlessly integrates with standard NEMA sockets |
This product isn’t just a small component—it plays a big role in the entire street lighting network. It links the photocell to street light fixtures. The light turns on or off by daylight. It is the smart core of dusk-to-dawn photocell lights. These lights save energy.
How Does It Improve Waterproof and Corrosion Resistance?
Weather is one of the harshest tests for outdoor lighting systems. From heavy rains to humid environments, poor sealing can quickly turn into system failure. Many traditional connectors fall short here. Moisture sneaks in. It causes rust. It weakens the connection. This causes lights to flicker. It can even lead to complete outages.
The key lies in its full glue sealing process. This way makes sure we leave no gaps. Water vapor cannot slip in. The JL200 has IP65-rated parts built in. This gives it a strong shield against rain, humidity, and condensation
Problema | JL200 Solution |
Water seepage into the contacts | Full glue seal + tight-fitting insulation |
Corrosion due to condensation | Use of anti-corrosive metals + full sealing |
Wire loosening from heat cycles | Enhanced glue adherence + stable contact housing |
Moreover, by sealing both external and internal contact points, the JL200 protects sensitive photocontrol components. This not only prevents failure but also extends the lifespan of the light sensor photocell switch.



What’s the Long-term Trade-off Between Cost and Maintenance?
Street lights are public investments—meant to last, not to fail repeatedly. While budget constraints often push cities to opt for low-cost parts, this leads to a cycle of frequent breakdowns, high maintenance, and hidden costs. The JL200 takes a different approach: invest slightly more upfront and save massively over time.
Yes, the JL200 Series might cost a bit more upfront—but that’s a tiny investment compared to future savings. Traditional low-cost receptacles often fail after 1–2 years in harsh environments, leading to frequent replacements and labor costs.
Vamos analisar:
Fator | Traditional Receptacle | JL200 Series 3pin Receptacle |
Initial Purchase Cost | Baixo | Médio |
Desempenho à prova d'água | Weak | Excellent (Full Glue + IP65) |
Maintenance Frequency | Alto | Muito baixo |
Replacement Cost Over 5 Years | High (Multiple Replacements) | Low (1-time Install) |
For municipalities or street light contractors, this trade-off adds up. One of our clients in coastal China saw a 45% drop in service calls after switching to JL200. That’s the kind of value that can’t be ignored.
How Does JL200 Compare to Competing Products?
There are so many products out there. You can feel lost in all the tech specs. Brand promises only add to the confusion. But performance in real conditions is where the JL200 shines. When you look closer at materials, sealing techniques, and life expectancy, not all receptacles are made equal.
Critérios | JL200 Series Receptacle | Competing Product A |
Waterproof Sealing | Full Glue Process | Partial Sealing or None |
Metal Sheet Coverage | Full | Partial |
Thickness of Terminal Parts | 0.8 mm | 0.5 mm |
Warranty Period | 5 Years | 2 Years |
Compatibilidade | NEMA + Zhaga | NEMA only |
The JL200 isn’t just a connector—it reflects Junção longa’s continuous innovation as a trusted photocell manufacturer. Every design element is backed by rigorous testing and user feedback.
How Do Heat Dissipation and Alignment Improve Performance?
Heat and misalignment are two silent killers in outdoor lighting. Overheating damages internal circuits, while poor orientation renders the photo sensor ineffective. Over time, these issues lead to sensor failures. They also make the lights behave erratically.


Street lighting fixtures generate a lot of heat. If heat can’t escape, it may harm connected parts. This damage can affect the photocell sensor and its receptacle. The JL200 has been designed with heat endurance in mind.
Not only does it withstand high thermal environments, but it also supports the airflow patterns common in LED street lighting fixtures. This reduces thermal stress e contact degradation.
And what about alignment? Many forget that a photocell control system depends on directional accuracy. The JL200 features a North-seeking marker, which ensures the photo sensor is always correctly oriented for optimal light detection.
Recurso | Função |
Heat Resistance | Prevents heat-induced failure of the photocell street light unit |
North-seeking Marker | Ensures sensor alignment for accurate dusk-to-dawn operation |
Vibration-Proof Housing | Secures contacts in fluctuating outdoor conditions |
By combining thermal resistance with correct orientation, the JL200 helps street lights stay smarter, longer.
Conclusão
When it comes to outdoor lighting, every component matters. The JL200 Series 3pin receptacle shows how much impact thoughtful design can have on system reliability and user safety.
It has strong waterproofing and fights off corrosion. Its smart alignment and built-in fit work with photocell street lights. It’s not just about performance. It’s about lasting value and trust.
With Long-Join, lighting control isn’t just technical—it’s purposeful.
