Description of the Invention: [Technical Field of the Invention] The present invention relates to a lighting fixture for a vehicle, and more particularly to a four-way low beam of an Adaptive Front-lighting System (AFS) Mode light LED headlights. [Prior Art] In order to further improve driving safety and driving convenience, the European Union proposed a draft of the Adjustable Front-lighting System (AFS) in 2003 and completed the ECE R123 regulation. Please refer to Figure 1 for a schematic diagram of the light patterns, test points and test areas required for each mode specification of the AFS low beam. The ECE R123 regulations add a variety of light-mode switching functions for road conditions, so AFS can be designed for basic (Basic), urban-rural (own), highway (Motorway) and wet road (Wet Road) lighting conditions. Light adjustment for optimal lighting. AFS low beam light distribution regulations ECE R123 requires at least two modes of vehicle front lighting system, that is, at least Class C (basic type) and at least one of the following: Class V (urban and rural), Class E (highway) Type), Class W (wet road type). The cutoff line of Class E and Class W is raised between 8° and +1.5° (compared to Class C and Class V), because only the correction near the HV point can not be raised by the entire lamp group (so The entire cut-off line is raised together to reach. At the same time, the AFS's low beam regulations require more than 200938413 (such as basic, urban and rural, highway and wet), and each M-type light distribution requirements are quite different ( Different shades of light and dark, different test points and maximum and minimum illumination values of the test area, etc.) In addition, AFS regulations require brighter, wider, flatter light distribution than current ECE regulations, which is quite difficult in optical design. High challenge. On the other hand, green lighting has become a trend in the development of global lighting products in recent years. Related companies are also actively investing in LEDs (led) Φ money on lighting research and development. For the relevant industry players, they also actively invest in the efficient white ED for vehicles (4). For example, China Patent Announcement No. 1258549, "Compliant with the appropriate road headlight lighting system (AF_ automotive LED near lamp) - case. The vehicle LED near lamp disclosed in the case, although it has been applied to AFS four low beam road conditions The design of the light type switching, but it requires eight modules, and each module f is the design method of the projection optical line. In addition, it is limited by the current high-brightness LED, low luminous efficiency and insufficient unit brightness. The single-chip white LED has the brightest luminous flux and 140 Lm. The existing method adopts the multi-module design method (such as the patent application). Although the multi-module design is more flexible in optical design. It's easy 'but when the headlights are installed in the real car, it will be limited by the limited space in front of the vehicle', so the applicability is greatly reduced. The existing AFS car light design, although for the AFS all kinds of multi-channel light type switching design However, its use of modules up to eight, and each mode, group is the design of the projection optical system, not only requires a large installation of empty doors but also increases costs. In the design of LED headlights, mainly targeted At present, the ECE regulations require a combination of these two development trends 7 200938413, which can meet the light-type requirements of all road conditions of the AFS regulations, and the light-emitting design of LED lighting for lighting, and the LED lighting with compact design to solve The foregoing problem is an object of the present invention to provide an LED lamp with four modes of light distribution in accordance with an adjustable front lighting system (AFS) low beam, which is used to solve the existing AFS LED lamp design.
