Fog lights are auxiliary lighting devices designed to improve road visibility under conditions of fog or foul weather such as heavy rain, snow, smoke, and dust storm. Front fog lights are typically mounted low in the front fascia of a vehicle and aimed downward to illuminate the road ahead of the vehicle. The fog lights produce a wide beam of light with a sharp cutoff at the top to reduce the glare created from reflected light and help prevent glare that may dazzle oncoming drivers.
A traditional fog light includes a halogen light bulb surrounded by a polyellipsoidal reflector that provides optical regulation. There may be a shade that is used to create a top cutoff in the produced light pattern. Halogen fog lights have low source and optical efficiencies. The fog lights typically consume around 55 watts of electrical power, which can be a substantial load on the vehicle’s electrical system. LED fog lights have become an essential selling point in the automotive industry due to the fundamental advantages of LEDs over traditional light sources. These advantages include lower power consumption, longer service life, higher optical delivery efficiency, exceptional vibration resistance, etc.
