Comparison of types of car headlights.

         Comparison of types of car headlights: Halogen bulbs: actually an improvement on incandescent bulbs used at home, emitting yellow light. Generally, economical household cars are equipped with halogen lamps, which are characterized by simple structure, low price, and strong penetration in rainy, snowy, and foggy weather. This is the main reason why they are not eliminated. The disadvantages are poor light brightness, relatively short lifespan, high wattage, and high power consumption. Some cheaper cars also use headlights. Xenon lamp: The xenon gas inside the bulb is ionized to produce an arc and emit light. After turning on the power, the 12V power supply is instantly raised to a high-voltage pulse voltage of over 20000 volts through a transformer, activating the xenon gas in the xenon bulb and emitting light, usually white light. Its advantages are high brightness and long lifespan. The disadvantage is that it has poor penetration in rainy, snowy, and foggy weather, reflects light, and is expensive. The original factory's single light bulb costs thousands. It is commonly used in mid to high end cars.

         Overview of LED headlights accessories for floor sweepers: LED lights are currently the best lights, with the advantages of high brightness, longest lifespan, lowest wattage, lowest power consumption, wide range of use, and can be used for low beam, high beam, brake light, and daytime running light. They can also be made into a beautiful shape. It can produce strong penetrating yellow light or weak penetrating white light. The disadvantage is that it is too expensive, but there are also many cars used nowadays, most of which are mid to high end cars. When driving on roads with streetlights, halogen lamps are sufficient. Turning on lights is mostly to let others see us, and the lighting effect is not significant. If you frequently use it on roads without streetlights and feel that the light is not bright enough, you can replace it with a super bright halogen bulb without changing any wiring, but be careful not to increase the wattage arbitrarily, as increasing the wattage can easily burn out the lamp holder. There are also aluminum parts behind the car lights for lighting and focusing, making the performance even better.

        What are the advantages of LED lights? High efficiency and low energy consumption. LED light sources can directly produce colors such as red and amber required for automotive lighting without the need for color filtering, with no loss and an energy utilization rate of over 80%; Lighting without delay, fast response time (nanosecond level), suitable for use with fast-moving objects; Long lifespan, generally up to 40000 to 100000 hours. Some people believe that if LED is used in future car lighting, it can basically be used for scrapping cars; Suitable for low voltage operation, there is no electrical pressure on car batteries; LED occupies a small volume, and designers can freely change the shape of the lamp, with diverse shapes.
