As a Welding Mould Manufacturer, we continue to introduce Types And Characteristics Of Several Common Headlamp Modifications.Nowadays, many car owners have converted the lights into xenon lights. I hope that everyone can use the lights reasonably for the safety of you and others.
The temperature of the LED headlights is very low, that is, 50-70 degrees, and it is instantaneously activated, and the power is turned on immediately. Now people change the lights, they all use LED headlights. Bright and power saving is the most remarkable feature of LED headlights. Just as energy-saving lamps replace incandescent bulbs, it is a trend. Take this time, often the riders got me to call me the "Nine Plus One Car LED Bulb E2", the function is only 33W, much more power than the original car halogen bulb, but the brightness is the original car At least 4 times more halogen bulbs! The LED headlight line is softer, not as dazzling as a xenon lamp, and evenly paving the road, it is not easy to visual fatigue, which is why people change LEDs for lighting now.
Energy saving, environmental protection, durability, small size and instant lighting are all the choices for car headlights. But for now, due to structural and cost constraints, it can only be applied to some high-end cars.
There is also a higher level of laser headlights, and now the new Audi A8 uses laser headlights.
Laser headlights have most of the advantages of LED headlights, such as fast response, low brightness attenuation, small size, low energy consumption, long life and so on. Compared to LED headlights, the laser headlights are particularly advantageous in terms of volume. The length of a single laser diode component can already be 10 microns, which is only 1/100 of the size of a conventional LED component. This means that as long as the designer is willing, the tradition The size of the car's headlights can be greatly reduced, which may revolutionize the design of the various elements on the front of the car.
Another significant advantage of laser headlights is that in terms of luminous efficiency, for example, the luminous efficiency of general LED lighting can reach about 100 lumens per watt, then the laser diode component can reach about 170 lumens per watt, which means that when the same illumination is met In terms of conditions, the use of laser headlights consumes less than 60% of the LED headlights, further reducing energy consumption and more in line with the future energy saving and environmental protection trends of automobiles.
Like LEDs, laser diodes can only emit monochromatic lasers. They need to be synthesized by multiple monochromatic laser sources, or they can be passed through transparent media such as quartz, resulting in broadening of the spectrum to form white light. BMW used the method commonly used by white LEDs - blue monochromatic light + fluorescent filters to make white light.
