Product Name: Lk3 3inch Auto Bi LED&Laser Projector Lens Model NO.: LK3 Certification: FDA Brand: Lightsattack Function: Dipped Headlight, High Beam, Laser Beam Voltage: 12V base: Universal Car Make: Universal Material: LED Warranty: 24months Trademark: LIGHTSATTACK Transport Package: Hard Cardboard Boxes and Inflatable Bags Specification: 3inch Origin: China Product Description INSTALLATION METHODThe installation method of the product is the same as that of ordinary lens products. The mounting hole position on the product is consistent with Haila 5, which is suitable for 95% of global vehicle models.PRODUCT LIGHTING SOURCESLED CHIP -We use Osram automotive-grade vertical chips with higher stability, higher luminous flux density, longer irradiation distances and higher illumination. It is preferable to use inorganic fluorescent materials and adopt dark-area-free packaging technology to make the light type fuller, no shadow stripes, and no blind spots in the illuminated area.LASER TUBE- We use laser tubes from well-known Japanese brands to ensure product life. In addition, for the entire laser module, we have set the internal light source. The laser is reflected through the device, which will not cause harm to the human body and eyes. It has also applied for US FDA laser certification registration to ensure product stability. LASER MODULE WORKING PRINCIPLEThe laser headlight is a new type of light source that combines multiple advantages and is the product of scientific and technological progress. Starting from the structure, the LK3 laser headlight includes four parts: a laser light source, a mirror, a filter and a light bowl. Its working principle is to let the laser go through five processes of "emission, focusing, penetration, and two reflections". First, a blue laser beam is emitted from the laser, then passes through the laser mirror, and then focused to the filter to generate white light. After that, it is reflected again on the luminous bowl, and finally forms a powerful beam with an irradiation distance of 1000meters.
