FEREI HL40AAII Headlights

Patented Smart Temperature Control Technology

• This product is designed with and uses a temperature control circuit device. LED is a heat-generating component sensitive to temperature, especially high-power, high-brightness LEDs, which are prone to damage or reduced lifespan due to excessive heat. FeRei uses an intelligent temperature control design, measuring the temperature of the LED chip. Due to the different structures of the lamp, the thermal conductivity varies. Generally, the surface temperature of the lamp is maintained between 50 and 60 degrees. When the set temperature is exceeded, the intelligent circuit drive of the lamp will automatically reduce the power to achieve cooling, during which the brightness of the lamp will also decrease. When the temperature drops (if the battery is sufficiently charged), the power will gradually increase, and so will the brightness; the process of increasing brightness is relatively smooth, avoiding flicker.

   

  This temperature control cycle effectively ensures user safety and extends the lamp’s lifespan. Under good air cooling conditions (low temperature or windy environments), the brightness of the lamp will not decrease even in high brightness mode. The lamp does not have a preset activation time for temperature control; it operates based on real-time temperature measurements, thus the actual illumination time depends on how the temperature control affects battery discharge, which may be slightly longer or shorter than the experimentally provided illumination time.
