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 lighting regulations ECE R123 requires at least two modes of vehicle front lighting, ie at least Class C (basic) and at least one of the following: Class V (urban and rural), Class E (high speed) Road 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 lighting regulations require a large number of light-to-size switches including 6 1322769 (such as basic, urban-rural, highway, and wet), and there are considerable differences in the light distribution requirements for each mode ( 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 involved in the development of lighting diodes (LED) for lighting. For those involved in automotive lighting, they are also actively investing in high-efficiency white LEDs for automotive lighting. For example, China Patent Announcement No. 1258549, "Conforms to the appropriate road headlight lighting system (eight" ^ vehicle LED near lamp". The vehicle LED near lamp disclosed in the case, although has been targeted at AFS four The design of the light type switching of the light road condition, but it requires eight modules, and each module is the design method of the projection optical system. In addition, the current high-intensity led light emission efficiency is low, and the unit brightness is insufficient (current city The luminous flux of white LEDs sold in a single form is about 140 Lm. The existing method uses a multi-module design (such as the patent application). Although the design of multiple modules is more flexible in optical design. And easy 'but when the headlights are installed in the real car, it will be limited by the limited space in front of the vehicle, resulting in greatly reduced applicability. Existing in the AFS car light design 'although for the AFS all multi-path light type switching Design, but it uses up to eight modules' and each module is a projection optical system design, which not only requires a large installation space, but also increases the cost. In the LED headlight design, mainly In order to comply with the current ECE regulations, it is necessary to combine the two development trends, and to meet the light-type requirements of all road conditions of the AFS regulations, the LED lighting design of the LED lighting, and the LED lighting with compact design The foregoing problem is solved. [The present invention] The object of the present invention is to provide an LED lamp with four modes of light distribution in accordance with an adjustable front lighting system (AFS) low beam, to solve the design of the existing AFS LED lamp. The problem of the large installation space requirement caused by the use of a plurality of modules. According to the present invention, an LED lamp with four modes of light distribution in accordance with the adjusted front lighting system (eight 1-8) has a first module and The second module is a projection optical system 'and includes a first mirror surface, a lens, and a light shielding device. The first mirror surface is a mirror surface of a multi-elliptical mirror design equation. The spherical lens device is disposed between the first mirror surface and the lens, and includes a first light shielding sheet and a second light shielding sheet, wherein the first light shielding sheet and the second light shielding sheet respectively have An upper edge, wherein the second visor is rotatably corresponding to the first visor, and when the second visor is disposed in parallel with the first visor, the upper edge of the second visor is higher than the first visor The first module includes a second mirror surface, and the second mirror surface is a three-dimensional non-axisymmetric geometry design mirror surface. In an embodiment, the multi-elliptical mirror design equation of the first mirror surface is: 1322769 ,) 々)-1 where α(^) = cos2 0 + ar sin2 0 , _ = λ/Ϊ^ + ~X2 coffee)-(a,T^, x is horizontal, γ is vertical, z is In the optical axis direction, θ is the angle, a is the half length of the major axis of the ellipse, b is the half length of the short axis of the ellipse, and 〇 is the focal length of the ellipse. e In one embodiment, the aspherical lens is designed by an aspherical lens quadratic equation, which is: P 4 z=^+coefxw f where r is radial, Z is the optical axis direction, and R is the radius of curvature of the vertex ' Coef is the coefficient of the adjustable concentrating effect. In the example of Equation Cl, the three-dimensional non-axisymmetric optical γ1 4 台 of the second mirror surface, where ^) = ^0052 ^ + , Γ is radial, Z is the optical axis direction, and R is the curvature integral coefficient. The second C is a light distribution. In one embodiment, the first module and the second module are respectively separated from each other, and the light source is a light emitting diode light source. α The effect that can be achieved by the invention is: With the new design of the dual module, the space requirement of the luminaire can be reduced to a minimum due to the practicality of the design result according to 9 1322769. The first module adopts a projection optical system, which is responsible for the light distribution in the strong light region near the HV point, and the two different shapes of the light shielding sheet can be switched in the projection optical system to form two kinds of light and dark cutoff lines required for light distribution. "The second module adopts an asymmetric mirror design, which is responsible for the light distribution in the farthest weak light region. The light source of each module only needs one LED' and can design different current magnitudes by the driving circuit, so that the LED light source generates different lumens, so that the light distribution of the dual modules can meet the four kinds of low beam respectively. Light and illuminance values for different lamps. At the same time, the present invention uses only two modules, and can simultaneously have the effect of miniaturization of LED lights. [Embodiment] FIG. 2 is a schematic diagram showing an LED lamp of a four-mode light distribution function of an adjustable front illumination system (AFS) low beam according to a preferred embodiment of the present invention. The LED lamp 1A of the preferred embodiment of the present invention comprises a first module 110 and a second module 丨2〇.

The light source of each module u〇l2〇 only needs one LED, and different current levels can be designed by the driving circuit, so that the LED light source generates different lumens, so that the light distribution stack generated by the dual modules can respectively meet the requirements. Light and illuminance values for four low beam needs. 10 1322769 The first core group 110 includes a first mirror surface ill, a lens 112, and a light shielding device 113. The first module 110 is provided with a light source 114, which may be a single light emitting diode. The function of the first mirror surface 111 is to condense the light beam emitted from the light source 114, so that an elliptical type surface can be used. In this embodiment, a multi-elliptical mirror design equation is employed. For example, the design equation of the multi-elliptical mirror disclosed in the Chinese Patent Publication No. 1261097 of the inventor of the present invention is: Χ2+Υ2 (ζ-α(θ)) 2 (1) (2) ~ ~〇w~ where α(θ) = αχ c〇s20 + arsin20 Φ) = -!(ax +cxP-a{0)-{ax+cx)\ (3) X : Horizontal direction Y : Vertical direction Z : Optical axis direction Θ : Angle a: Ellipse The half length of the long axis b: the half length of the short axis of the ellipse c: the focal length of the ellipse When ax off aY, bx off bY, the horizontal and vertical directions are respectively elliptical shapes of different shapes, so that a non-axisymmetric light shape can be generated So in line with the driving needs 11 1322769 seeking wide but not high light distribution. The function of the lens m is to concentrate the beam, which can be designed by aspherical lens. In the present, the system is invented by the inventor of the aspherical lens. The fourth-surface equation (5) Yuan Chang, Lai Tianxing, 2GG2G9, focusing on the aspherical thick lens t Design, Optical Engineering Quarterly, pp. 49-56 'No. 79): where r is radial, Z is the optical axis direction 'R is the radius of curvature of the apex, and (5) is the coefficient of the adjustable concentrating effect, and its focusing ability is better. All secondary conical surfaces are preferred. Referring to Figures 3a to 3d, the function of the visor device 113 is to form a cut-off line, and the light-switching package required by the AFS's low-beam regulations. There are four modes (basic, urban-rural, highway) Light, which is divided into two different light and dark cut-off lines. In this =, the light shielding device 113 is disposed between the first mirror surface lu and the lens ι 2, and includes two different shapes of the first light shielding sheet 115 and the second light shielding. The spring sheet 116. The first light shielding sheet 115 and the second light shielding sheet 116 are switchable to form two kinds of cut-off lines required for light distribution. The first light shielding sheet 115 can form a cut-off line of Class E and Class W. The two visors 116 can form a cut-off line of class C and Class V, wherein the first visor 115 is fixedly held upright, and the second visor 6 can be rotated relative to the first visor 5 by a rotating mechanism 13 The first light shielding sheet 115 has an upper edge 117. The first light shielding sheet 116 has an upper edge 118. When the second light shielding sheet 116 is erected, it is closely attached to the first light shielding sheet 115. 12 1322769 or when configured in parallel, The upper edge 118 of the two light shielding sheets 116 is higher than the upper edge 117 of the first light shielding sheet 5, so that the cut-off line of the light shape is caused by the upper edge 118 of the second light shielding sheet 116, so that the light and dark of the Class C and the Class V are formed. When the second light shielding sheet 116 is laid flat, only the first light shielding sheet 115 is erected, so that the cut-off line of the light shape is caused by the upper edge 117 of the first light shielding sheet 115, so that the Class E and the Class are formed.
