Cities are becoming smarter—and so are their lights. Rising energy costs and growing demands for sustainability have rendered traditional streetlights a mismatch. Municipalities now seek lighting systems that save power and last longer. That’s where intelligent контроллеры света come in. These smart devices respond to natural light, optimizing when and how streetlights operate. Longjoin leads this shift, offering advanced photocells designed to cut energy use and extend light lifespan. Built with innovation at their core, Longjoin solutions are shaping the future of urban lighting.
Как Фотоконтроллеры Work To Save Energy?

Intelligent Light Detection for Automated Switching
Manual lighting control in cities is inefficient and error-prone. Automated systems that react to ambient light offer better energy use.
Лонгджойн Светодиодный уличный фотоэлемент use advanced photoelectric sensors to detect environmental light levels. When light drops below a set point, the system turns on. When daylight returns, the system turns off. This process ensures lights operate only when needed. It cuts energy use and lowers running costs.
Delayed Control for Smooth Lighting Transitions
Sudden light changes—like lightning or headlights—can cause false triggers. A delay mechanism prevents this and keeps the lighting stable.
Longjoin products include a time-delay feature of 30 to 120 seconds. Here is how it benefits:
- This filters out short-term changes in light.
- It prevents unnecessary switching.
- It protects components and improves their lifespan.
- The time delay feature also effectively boosts the overall efficiency of lighting systems.
Light Decay Compensation Technology for Consistent Illumination
LEDs and other fixtures dim over time due to lumen depreciation. This can reduce lighting quality. Here is a table showing light decay imapcts lighting over time.
Operating Hours | Lumen Maintenance Level | Описание |
10,000 hours | ~95% | Slight reduction; LEDs maintain high efficiency |
25,000 hours | ~90% | Noticeable depreciation begins; planning for maintenance is advisable |
50,000 hours | ~80% | Significant depreciation; common benchmark for L70 rating |
100,000 hours | ~70% | Typical end-of-life threshold for many LED products |
Longjoin solves this with light decay compensation technology. The system adjusts output as the fixture ages. This keeps brightness consistent, improves visibility, and extends fixture life. It also supports long-term energy savings.
What Technologies Are Used In Фотодатчики To Boost Energy Efficiency?


Light Decay Compensation for Optimized Lighting Output
LED luminaires lose brightness over time due to lumen depreciation. This affects lighting quality and safety. Maintaining stable light levels is essential for visibility and efficiency.
Лонгджойн фотоконтрольные розетки solve this with light decay compensation. The system auto-adjusts output to keep brightness steady. This ensures proper lighting, extends fixture life, and improves long-term performance.
Low-Energy Design Reducing Controller Consumption
Control devices also impact total energy use. Efficient designs can save power without lowering performance.
Longjoin’s JL-423C and 423CM models follow this principle. They use just 0.4W at most. This low consumption comes from IR-filtered phototransistors and smart circuitry. The result is a dependable function with minimal energy draw.
Smart Control Integration for Refined Lighting Management
Smart controls improve lighting precision and automation. They also simplify system management.
Лонгджойн автоматические датчики освещенности support protocols like 0–10V, PWM, and DALI. These interfaces allow dimming, scene control, and remote monitoring. They make the system more responsive and ready for IoT or building integration.
Here is a table detailing different lighting control protocols, their benefits, and applications.
Протокол управления | Описание | Приложение | Выгода |
0–10В | Analog dimming signal | Basic dimming control | Простой и экономичный |
ШИМ | Широтно-импульсная модуляция | LED brightness modulation | Precise dimming control |
ДАЛИ | Интерфейс цифрового адресуемого освещения | Smart building integration | Scalable, two-way communication |
Зигби | Wireless mesh protocol | IoT and remote control | Remote diagnostics and updates |
How Do LongJoin Контроллер уличного освещения Extend Streetlights’ Lifespans?
Reducing Overuse and Wear Through Precise Control
Frequent switching shortens the lifespan of streetlights. Overuse also leads to wasted energy and higher costs. Using precise control mechanisms ensures lights run only when needed.
Лонгджойн фотоэлементные выключатели света feature smart light detection and delay functions that effectively counter this. Here’s how:
- They block false triggers caused by things like lightning or passing cars.
- This reduces on/off cycles, lessening stress on components.
- As a result, the system lasts longer and runs more efficiently.
High-Quality Materials and Design for Durability
Streetlights face tough weather and must be built to last. Longjoin photocells use durable materials and undergo strict testing. These materials support IP65 and IP67 protection ratings. They guard against dust and water in demanding environments.
The датчики света also perform in extreme temperatures, from -40°C to +70°C. This ensures stable function in both cold winters and hot summers.
Here is a table of different materials used in LongJoin Photocell manufacturing and their respective specifications.
Component | Материал | Технические характеристики | Преимущества |
Photocell Base (e.g., JL-241J)\ | PBT (Polybutylene Terephthalate) | High thermal stability, flame retardant, UL94-V0 flammability rating | Ensures structural integrity under high temperatures and provides safety against fire hazards. |
Photocell Cover | Polycarbonate (PC) | UV-resistant, high-impact strength | Protects internal components from UV degradation and physical damage, enhancing durability |
Sealing Gasket | Rubber/Silicone | Weather-resistant, flexible | Provides effective sealing against moisture and dust ingress, ensuring IP65/IP66 protection |
Contact Pins | Copper | Excellent electrical conductivity | Ensures reliable electrical connections, reducing power loss and enhancing performance |
Sensor Component | IR-Filtered Phototransistor | Accurate light detection | Enhances sensitivity and reduces false triggering, ensuring precise operation |
Smart Diagnostics and Warning Systems for Proactive Maintenance
Unexpected failures increase costs and create safety risks. Proactive maintenance helps extend system life and prevent breakdowns. Longjoin датчики фотопереключателя use Zigbee and NB-IOT for wireless monitoring, another type can development an wireless LoRa (here have quantities limitment) . They detect issues like voltage spikes or component faults. Alerts go out instantly so maintenance teams can act fast.
For example, the SOS beacon feature lets a controller flash or change color to signal emergencies. This keeps systems online and lowers downtime. Integration with the UM9000 platform adds even more control.
It allows centralized management, fault detection, and data analysis. Together, these tools reduce costs and boost system reliability.
