In one embodiment of the present invention, as shown in fig. 1 and 2, the dipped headlight 1 is installed in front of a vehicle 100 to provide illumination and warning effects for oncoming traffic. In order to avoid the interference of the light of the low beam lamp 1 with the view of the oncoming vehicle, the light pattern of the lamp must have a step in the general legal regulations, and the cut-off line of the lower region must be kept flat, and there is a luminance limitation in the lower partial region of the lower cut-off line at about 3.4 to 3.5 degrees from the center, whereas the low beam lamp 1 according to the present invention is designed to generate a special light pattern that meets the legal regulations, and the details of the design of the low beam lamp 1 according to the present invention will be explained in detail below. The low beam vehicular lamp 1 of the present invention comprises a first reflector 10, a second reflector 20, a third reflector 30, a circuit board 40, a light shielding plate 50, a lens 60 and a lens fastener 70.
In an embodiment of the invention, as shown in fig. 2, 4 to 6, the first reflecting plate 10 is an arc-shaped reflecting shell formed by combining a variable focal length ellipsoid and a parabolic surface, and the first reflecting plate 10 has a first focal point 11 and a second focal point 12. The first reflector 10 is used for reflecting light emitted from a light source on the circuit board 40 to the light shielding plate 50 and the lens 60, the circuit board 40 has a first light emitting unit 41, and the first light emitting unit 41 is a light emitting diode disposed at the first focal point 11 to emit a light beam to the first reflector 10 and reflect the light beam through the second focal point 12. The mask 50 includes a leading edge 51, a raised structure 52 and an upper surface 53. The front edge 51 is an arc-shaped concave edge, and the second focus 12 is located on the front edge 51 of the light shielding plate 50. The convex structures 52 are used to shield a portion of the light reflected by the first reflective plate 10, so that the light pattern finally projected through the lens has a local dark spot. The upper surface 53 is a surface of the light shielding plate 50 facing a side of the first reflection plate 10, the second reflection plate 20, and the third reflection plate 30. Raised structures 52 are located on upper surface 53. The lens 60 is disposed in front of the light shielding plate 50. The lens 60 has a lens focus 61, and the lens focus 61 is located at the leading edge 51 of the mask 50. When the first light emitting unit 41 emits the light beam to the first reflection plate 10, the first reflected light beam A, A 'is generated and emitted to the second focal point 12, wherein a portion of the first reflected light beam a is shielded by the light shielding plate 50, so that the portion of the first reflected light beam a is reflected again and penetrates through the lens 60 to form a first light pattern L1 with a height difference of the cut-off edge S, and another portion of the first reflected light beam a' is shielded by the convex structure 52, so that a dark region D is formed beside the cut-off edge S of the first light pattern L1. If the position where the cut-off edge S starts to be lowered is set as the center X, the shadow area D is located at a lower portion of the lower cut-off line from the center X by about 3.4 to 3.5 degrees.
The first reflection plate 10 is positioned between the second reflection plate 20 and the third reflection plate 30, and the first reflection plate 10 connects the second reflection plate 20 and the third reflection plate 30. In one embodiment of the present invention, the second reflector 20 is a compound surface reflector shell formed by combining a parabolic curved surface and a generally ellipsoidal surface, and the second reflector 20 has a second reflector focus 21. The second reflective plate 20 is used to reflect light emitted from the light source on the circuit board 40 to the light shielding plate 50 and the lens 60.
In one embodiment of the present invention, the third reflector 30 is a compound surface reflector shell formed by combining a parabolic curved surface and a generally ellipsoidal surface, and the third reflector 30 has a third reflector focus 31. The third reflector 30 is used to reflect the light emitted from the light source on the circuit board 40 to the light shielding plate 50 and the lens 60.
In an embodiment of the present invention, the circuit board 40 is disposed under the first, second, and third reflection plates 10, 20, and 30. The circuit board 40 further has a second light emitting unit 42 and a third light emitting unit 43. The second and third light emitting units 42 and 43 are light emitting diodes. The second light emitting unit 42 is disposed at the second reflection plate focal point 21 to emit a light beam toward the second reflection plate 20. The third light emitting unit 43 is disposed at the third reflection plate focal point 31 to emit a light beam toward the third reflection plate 30.
In an embodiment of the present invention, as shown in fig. 2 to 4, the light shielding plate 50 is a mirror plate for shielding the light reflected by each reflective plate and secondarily reflecting the light reflected by the reflective plate to the lens 60 to generate a special light pattern meeting the regulations. The light shielding plate 50 is disposed in front of the circuit board 40. The mask 50 further includes a first light shielding structure 54, a second light shielding structure 55, an edge 56 and two spot eliminating structures 57 and 57 a. The first light shielding structure 54 and the second light shielding structure 55 are used for shielding the light reflected by the first reflection plate 10, the second reflection plate 20 and the third reflection plate 30, so that the cut-off edge of the light pattern finally projected to the outside through the lens presents a height difference. The height of the first light shielding structure 54 is higher than that of the second light shielding structure 55. The first light shield 54 includes an edge 56, the edge 56 being adjacent to the second light shield 55. The raised structure 52 is located on the upper surface 53 and on the first light shield structure 54, and the raised structure 52 is adjacent to the edge 56. The two spot eliminating structures 57 and 57a are located on the front edge 51, the two spot eliminating structures 57 and 57a respectively include an atomizing surface 571 and 571a, and the atomizing surface 571 and 571a are rough surfaces formed by atomizing or sandblasting the surface on the upper side of the front edge 51. The atomization surfaces 571 and 571a are used to scatter the light reflected to the atomization surfaces 571 and 571a, so that the scattered light cannot be emitted to the lens 60. However, the number of the spot eliminating structures 57 is not limited to two, and may be changed to one or more according to design requirements.
In an embodiment of the present invention, the lens fixing member 70 is used to fix the lens 60 and connect the first reflection plate 10, the second reflection plate 20 and the third reflection plate 30.
As shown in fig. 4 to 6, when the user activates the dipped headlight 1 to illuminate, the first light-emitting unit 41, the second light-emitting unit 42 and the third light-emitting unit 43 of the circuit board 40 all emit light. The first light emitting unit 41 located at the first focal point 11 emits a light beam toward the first reflection plate 10, and the first reflection plate 10 receiving the light beam generates a first reflected light beam A, A' and emits it toward the second focal point 12. A part of the first reflected light beam a is shielded by the first light shielding structure 54 and the second light shielding structure 55 having a height difference of the light shielding plate 50 to generate a cutoff line having a height difference on the light pattern; the part of the first reflected light beam a passes through the lens 60 again and irradiates to the outside, and forms a first light pattern L1 (i.e. the area drawn by the flat thin dot in the center of fig. 5) with a height difference at the cut-off edge S, where the position of the first light pattern L1 is approximately below the center X, at the lower left corner and at the lower right corner. Meanwhile, another part of the first reflected light beam a 'is shielded by the protruding structure 52 and cannot be emitted to the outside or the brightness of the first reflected light beam a' is reduced, so that a dark region D is formed near the cut-off edge S of the first light pattern L1.
In addition, the second light emitting unit 42 located at the focal point 21 of the second reflection plate emits a light beam to the second reflection plate 20, the second reflection plate 20 receiving the light beam generates a second reflected light beam B, B ', and the second reflected light beam B, B' is emitted to the light blocking plate 50. A part of the second reflected light beam B is shielded by the first light shielding structure 54 and the second light shielding structure 55 having a height difference of the light shielding plate 50 to generate a cutoff line having a height difference on the light pattern; the part of the second reflected light beam B passes through the lens 60 again and irradiates to the outside, and forms a second light type first area L2a (i.e. the area drawn by the denser irregular thin dots on the left side of fig. 5), the position of the second light type first area L2a is approximately located below the center X and at the lower left corner, and the light type length extends further to the left. The cut-off edge S1 of the second reflected light beam B is close to a line with height difference by the shielding of the light shielding plate 50 with height difference structure, but the cut-off edge S1 is not limited thereto, for example, in order to generate a light pattern (the cut-off edge is a straight line) conforming to the light pattern of the motorcycle, the light shielding plate 50 may be designed to be flat and have no height difference, so that the cut-off edge is a straight line. Meanwhile, another part of the second reflected light beam B 'is shielded by the protruding structure 52 and cannot be emitted to the outside or the brightness of the second reflected light beam B' is reduced, so that a dark area D1 is located beside the cut-off edge S1 of the first light pattern region L2 a.
Meanwhile, the third light emitting unit 43 located at the focal point 31 of the third reflective plate emits a light beam toward the third reflective plate 30, the third reflective plate 30 receiving the light beam generates a third reflected light beam C, C ', and the third reflected light beam C, C' is emitted toward the light shielding plate 50. A bright-dark cut-off line having a height difference is created in the light type by the third reflected light beam C, C' being shielded by the first light-shielding structure 54 and the second light-shielding structure 55 having a height difference of the light-shielding plate 50; the third reflected light beam C, C' penetrates the lens 60 again to illuminate outside, and forms a second light pattern second region L2b (i.e., the region drawn by the sparse flat thin dots on the right side of fig. 5), where the second light pattern second region L2b is located substantially below the center X and at the lower right corner, and the light pattern length extends further to the right. The third reflected light beam C, C 'is not shielded by the protruding structure 52, so the third reflected light beam C, C' is not unable to emit to the outside or reduce the brightness like the first reflected light beam a 'and the second reflected light beam B', and the second light pattern region L2B does not generate a dark area. The cut-off edge S2 of the third reflected light beam C, C' is close to a line with height difference by the shielding of the light shielding plate 50 with height difference structure, but the cut-off edge S2 is not limited thereto, for example, in order to generate a light pattern (the cut-off edge is a straight line) conforming to the light pattern of the motorcycle, the light shielding plate 50 may be designed to be flat and have no height difference, so that the cut-off edge is a straight line.
The second light pattern first region L2a formed by the second reflected light beam B, B ' passing through the lens 60, the second light pattern second region L2b formed by the third reflected light beam C, C ', and the first light pattern L1 formed by the first reflected light beam A, A ' passing through the lens 60 are overlapped to form a second light pattern L2 with a cut-off edge S3 having a height difference. The width of the second light pattern L2 is greater than the width of the first light pattern L1. The dark region D and the dark region D1 overlap.
In addition, in the vehicle lamp using the lens, when light with different wavelengths passes through the lens, dispersion occurs due to different refraction angles, and yellow or blue-violet light spots are formed on the cut-off edge of the light. However, in the dipped headlight 1 of the present invention, the reflected light beam irradiates the atomization surfaces 571 and 571a on the front edge 51, and the atomization surfaces 571 and 571a scatter the light beams with different wavelengths reflected to the atomization surfaces 571 and 571a, so that part of the scattered light cannot be refracted by the lens 60, and the yellow or blue-violet light spots on the cut-off edge are reduced, so that the cut-off edge is clearer.
By the structural design of the dipped headlight, the light type irradiated by the dipped headlight has the cut-off line and light type distribution which meet the regulation, and yellow or blue-violet light spots generated on the cut-off edge can be reduced, so that the cut-off edge is clearer.
It should be noted that the above embodiments only illustrate the preferred embodiments of the present invention, and all possible combinations of the variations are not described in detail for avoiding redundancy. However, one of ordinary skill in the art should appreciate that each of the modules or assemblies described above is not necessarily required. And other well-known modules or components may be included for performing the invention in more detail.
