2019-10-28 17:09:42

2元彩票新疆35选7 www.djvkg.tw Take Audi laser headlamp as an example. The light source of laser headlamp is laser diode. Blue laser converts it into white light through scales, and irradiates it on a 3mm lens. The lens redirects the laser to the digital micromirror converter, which projects the laser to the road through hundreds of independent adjustable micromirrors inside. And each LED light-emitting element can be turned on, dimmed or off independently. If the number of light-emitting elements allows, matrix LED lamp can combine millions of lights. Compared with LED headlamp, laser headlamp has higher brightness, longer irradiation distance, smaller lamp volume, 30% lower energy consumption and longer service life; the disadvantage is high manufacturing cost. At the same time, they are all high-tech lighting products, which can save the electric energy of the vehicle and improve the illumination, which can greatly improve the driver's active safety when driving.
