The service life of the light source in Shanghai 3S Technology's photocatalytic reactors varies significantly depending on the technical configuration. The core products of the company employ an LED light source system. The standard models have a service life of over 20,000 hours, and some high-end models achieve a service life exceeding 50,000 hours through optimized heat dissipation structures and chip packaging processes. For instance, the LED arrays equipped in the AF series photocatalytic reactors exhibit a light intensity decay rate of less than 10% after 20,000 hours of continuous operation in laboratory conditions, far surpassing the performance of traditional xenon lamps (1,000 - 3,000 hours) and mercury lamps (5,000 - 8,000 hours).

In practical applications, the service life of the light source is closely related to experimental conditions. 3S Technology (Shanghai) ensures stable operation of the light source even under extreme reaction conditions (such as the degradation of strong oxidizing substances) through an intelligent temperature control system that maintains temperature fluctuations within the reaction chamber at ±1°C, combined with explosion-proof valves and circulating water cooling devices.
