Automatic tunnel lighting Scene Dimming by Ambient Sensor

The  Street Light CCT Sensor aims at the using environment of street lighting, tunnels etc., through the abnormal changing ambient, the lighting fixtures are automatically controlled according to programming to realize intelligent lighting management. Traditional street lightings,  tunnels, factories lighting fixtures are mostly controlled by personnel inspection or regular control, which initially meets the needs of the scene, but still cannot achieve the effect of intelligent control. For example: Turn on or dimming to brighter when people is coming, and turn lights off when people go away; No matter which direction the person enters from, the lamps in the area will automatically light up or increase according to the setting; this equipment cooperates with the intelligent lamps to solve these problemsperfectly. It adopts the most advanced and popular LoRa wireless communication technology, the communication distance can reach 3 kilometers without repeater, and the actual measurement reach 1 kilometers, and the communication distance is adjustable.

Why Choose an IoT-Enabled Hybrid Solar + Grid Street Lighting System? Modern cities are experiencing rapid expansion, rising energy demand, and an increasing need for reliable public infrastructure. Street lighting is one of the largest electricity consumers in any municipality, and traditional grid-powered lighting systems often struggle with high operating costs, unstable power supply, and limited management capability. At the same time, purely solar street lights face their own challenges, such as insufficient sunlight during rainy or cloudy seasons, battery degradation, and inconsistent performance in regions with harsh climates. These issues have created a strong global demand for a more resilient, intelligent, and cost-effective lighting solution—leading to the rise of IoT-enabled hybrid solar + grid street lighting systems. A hybrid street lighting system integrates three essential components: solar energy, the local electrical grid, and a high-cycle LiFePO4 battery backup. During sunny days, the solar panel provides power and charges the battery. At night or during cloudy periods, the system intelligently switches to battery or low-tariff grid electricity depending on availability. This dual-source architecture solves the “solar only” reliability problem while significantly reducing dependence on expensive peak-hour grid electricity. Cities benefit from lower electricity bills, improved lighting reliability, and reduced CO₂ emissions without compromising performance. The addition of IoT technology further transforms the system from a basic lighting device into a smart, data-driven infrastructure asset. With IoT lamp-level controllers, each street light can report real-time information such as voltage, current, temperature, battery state of charge, and power consumption. Faults—such as LED failure, low battery, or power loss—are automatically detected and sent to a centralized monitoring platform. This enables cities to replace traditional manual inspection with predictive maintenance, reducing manpower costs and minimizing downtime. IoT also enables precise lighting control. Municipalities can schedule automatic ON/OFF times, dim lights during low-traffic hours, or adjust brightness in response to weather, road conditions, or special events. When applied across thousands of street lights, these small adjustments can reduce energy consumption by 30% to 70%. Combined with hybrid power, cities can ensure that every roadway, rural village, industrial zone, or highway retains stable lighting even during extended rainy seasons, power outages, or natural disasters. For developing countries or regions with unstable grids, hybrid solar + grid IoT street lights offer an especially powerful advantage: continuous lighting security. Frequent blackouts are no longer a threat, and the system can maintain illumination for several nights using battery backup alone. This significantly improves road safety, reduces crime risk, and supports 24-hour economic ...

SOWIN GXEC Spiral & Helical Quartz-Glass Xenon Flash Tube is engineered for high-intensity professional photography and stroboscope devices where the requirement is not “it flashes,” but repeatable pulse output, stable ignition, and predictable lifetime under sustained operation. The spiral/helical geometry supports a compact optical package and improves light-field coverage for reflectors and cavities, helping deliver a more uniform usable light zone. For high repetition and long duty cycles, this design helps reduce hidden failure modes such as misfire, brightness drift, and early blackening when the system is operated inside a verified window. Procurement sign-off rule: do not replace spiral/helical xenon tubes by appearance. A valid replacement must match the trigger method and the verified energy / frequency / duty-cycle window. Unverified substitution carries real cost: misfire, output drift, blackening, and premature failures can trigger downtime, rework, and warranty loss. If you swap “by guess”, you pay twice: first in performance instability, then in replacement labor, downtime, and rejected results. If needed, we can provide an engineer-reviewed parameter sheet and a replacement checklist to support integration review and maintenance standardization.
