I. Core Component Lifespan: Infrared Lamp Type is Key
Infrared lamps are a core factor affecting the overall lifespan of the device, with significant differences between different types:
1. Single-chip LED: Mature manufacturing process, low heat generation, and reasonable optical system; lifespan can reach over 100,000 hours, making it the preferred choice for high-end models.
2. Multi-chip LED: Although with long illumination distance, heat dissipation is difficult, operating temperature is high, and chip failure is easily caused by localized overheating; lifespan is generally less than 30,000 hours.
3. Halogen Lamp: High energy consumption, high heat generation, and short lifespan, generally only 5,000-8,000 hours; it is gradually being phased out.
✅ It is recommended to prioritize models using single-chip LEDs and confirm whether high-grade LED chips are used, as they offer better consistency, higher luminous efficiency, and stronger heat resistance.
II. Heat Dissipation Design Directly Affects Long-Term Stability
Temperature is the "number one killer" of infrared lamp lifespan. High temperatures accelerate LED aging, reduce radiation power, and can even burn out the CCD sensor.
1. Superior Design: Utilizing an integrated aluminum alloy lamp board and housing heat dissipation structure, combined with constant current power supply and pulse width modulation technology, it ensures that the long-term operating temperature does not exceed 50℃, effectively extending lifespan.
2. Inferior Products: Lacking effective heat dissipation measures, the LED board temperature can reach approximately 90℃, significantly shortening its lifespan.
🔧 When purchasing, check if the product is labeled with keywords such as "constant current power supply," "intelligent temperature control," and "aluminum-based heat sink."
III. Operating Current and Voltage Control are Crucial
LEDs are extremely sensitive to current and voltage:
1. Excessive Current: While it may temporarily increase brightness, it significantly increases heat generation, leading to rapid LED decay or burnout.
2. Unstable Voltage: Slightly high voltage may damage the chip, while slightly low voltage will cause a sharp drop in light output. It is recommended to use a 170V~270V wide-input switching power supply to adapt to complex power supply environments.
⚠️ Products without constant current design or protection circuitry may have an actual lifespan of less than half of the nominal value.
IV. Protection Rating and Environmental Adaptability Determine Durability
1. IP66 and above protection ratings provide dust and water resistance, preventing moisture intrusion that could cause short circuits or fogging.
2. Operating temperature range should cover -40℃ to +60℃ to ensure stable operation in extreme environments.
3. Sealing technology and cable materials also affect lifespan. High-quality products use cables that are resistant to high and low temperatures and bending, improving overall reliability.
