As shown in fig. 2, divergent light emitted from the light source 101 is reflected by the reflecting mirror 102 and then converged near the focal point of the lens 104, wherein a part of the light is blocked by the light blocking structure 103a of the light blocking plate 3 to form a dark area, and the rest of the light is refracted by the lens 104 to the road surface to form illumination, thereby forming a near-beam illumination light shape similar to parallel light with a cutoff line.

As shown in fig. 4 to 16, an embodiment of the lamp projection unit of the present invention.
As shown in fig. 4 and 5, the lamp projection unit of the present invention includes a light source 1, a reflector 2, and a lens 3. The light source 1 preferably employs an LED (Light Emitting Diode ) light emitting chip. The lens 3 has an entrance face 3a, an exit face 3b and a focal point. The mirror 2 has a reflecting surface 2a, the reflecting surface 2a of the mirror 2 is preferably ellipsoidal, and the mirror 2 has a near focus F1 and a far focus F2. The light source 1 is arranged at a near focus F1 of the mirror 2, and a far focus F2 of the mirror 2 is located near the focus of the lens 3. The light emitted from the light source 1 is reflected by the reflecting surface 2a of the reflecting mirror 2 and then converged at the far focal point F2 of the reflecting mirror 2, that is, in the vicinity of the focal point of the lens 3. The light converged at the far focus F2 of the reflector 2 is incident on the lens 3, is refracted once by the incident surface 3a of the lens 3 and refracted twice by the exit surface 3b of the lens 3, and then irradiates the road surface to form an illumination light shape. Therefore, the light path of the incident light is controlled by the lens 3 to form a required illumination light shape, compared with a traditional car light projection unit, the car light projection unit has a simple structure, and a light shielding plate structure for forming a cut-off line is omitted, so that the fluctuation of the optical performance of the car light projection unit caused by the manufacturing error of parts and the assembly error among parts is reduced, the product qualification rate can be effectively improved, the light loss caused by shielding of part of light by the light shielding plate is avoided, and the light efficiency is improved.
As shown in fig. 6, in the first embodiment, the incident surface 3a of the lens 3 may be a flat surface or a curved surface. The exit surface 3b of the lens 3 is a curved surface, and the curved surface has an inflection point F3, the inflection point F3 and the focal point of the lens 3, the near focal point F1 and the far focal point F2 of the reflecting mirror 2 are all located on the same straight line, and when the normal line of the curved surface (the exit surface 3b of the lens 3) at the inflection point F3 is set to be the horizontal line a, the included angles between the normal line of the side surfaces of the curved surface (the exit surface 3b of the lens 3) located at both sides of the inflection point F3 and the horizontal line a are gradually increased along the direction away from the inflection point F3, i.e., θ2 shown in fig. 6 is greater than θ1. Then according to the angle of the incident light and the law of refraction of the light:
n 1 sini＝n 2 sinr
wherein i is the incident angle, n 1 The refractive index of the medium corresponding to the incident angle i, r is the exit angle, n 2 The refractive index of the medium corresponding to the exit angle r.
It can be seen that, after the incident light is refracted once by the incident surface 3a of the lens 3 and secondarily refracted by the emergent surface 3b of the lens 3, the included angle between the emergent light and the horizontal line a will gradually increase along the direction away from the inflection point F3, i.e. α2 is greater than α1 as shown in fig. 6. Therefore, when the light emitted by one light source 1 is reflected by the reflecting surface 2a of the reflecting mirror 2 and is converged at the far focus F2 of the reflecting mirror 2 and is incident into the lens 3 at a certain angle, the light is refracted by the incident surface 3a and the emergent surface 3b of the lens 3 and passes through the lens 3, and then only one side (e.g. the lower side in fig. 6) of the horizontal line a forms illumination light with uniform transition intensity, and the other side (e.g. the upper side in fig. 6) of the horizontal line a does not form illumination light, so that the horizontal line a is a cut-off line of the illumination light shape of the vehicle lamp, and the effects of preventing the glare of the vehicle lamp illumination on drivers of other vehicles on the road and ensuring driving safety can be achieved.
As shown in fig. 7, 8 and 9, in the second embodiment, the exit surface 3b of the lens 3 may be a flat surface or a curved surface. The incident surface 3a of the lens 3 is a curved surface, and the curved surface has an inflection point F3. The inflection point F3 is on the same straight line as the focal point of the lens 3, the near focal point F1 and the far focal point F2 of the reflecting mirror 2, and when the normal line of the curved surface (the incident surface 3a of the lens 3) at the inflection point F3 is set to be the horizontal line a, the angles between the normal line of the side surfaces of the curved surface (the incident surface 3a of the lens 3) on both sides of the inflection point F3 and the horizontal line a are gradually increased in the direction away from the inflection point F3, that is, θ2 is larger than θ1 as shown in fig. 9. As in the first embodiment, after the incident light is refracted once by the incident surface 3a of the lens 3 and secondarily refracted by the exit surface 3b of the lens 3, the included angle between the emitted light and the horizontal line a will gradually increase in a direction away from the inflection point F3, i.e., α2 is greater than α1 as shown in fig. 9. Therefore, when the light emitted by one light source 1 is reflected by the reflecting surface 2a of the reflecting mirror 2 and is converged at the far focus F2 of the reflecting mirror 2 and is incident into the lens 3 at a certain angle, the light is refracted by the incident surface 3a and the emergent surface 3b of the lens 3 and passes through the lens 3, and then only one side (e.g. the lower side in fig. 9) of the horizontal line a forms an illumination light with uniform transition intensity, and the other side (e.g. the upper side in fig. 9) of the horizontal line a does not form an illumination light, so that the horizontal line a is a cut-off line of the illumination light shape of the vehicle lamp.
In the present invention, the curvature and curvature change rate of the incident surface 3a and the exit surface 3b of the lens 3 are designed according to the required illumination light shape and light intensity distribution. The required cutoff line of the illumination light pattern can be obtained by designing the curvatures of the incident surface 3a and the exit surface 3b of the lens 3, and the required light intensity distribution of the illumination light pattern can be obtained by designing the curvature change rates of the incident surface 3a and the exit surface 3b of the lens 3. Therefore, the curvature and curvature change rate of the incident surface 3a and the exit surface 3b of the lens 3 are not limited in the present invention, and should be designed and obtained according to the actual lighting requirements of the vehicle lamp, so as to obtain a corresponding lighting pattern, such as a pattern with a horizontal cutoff line as shown in fig. 14, a pattern with a low beam cutoff line as shown in fig. 15, and a pattern with a high beam and a low beam as shown in fig. 16.
In the first embodiment (as shown in fig. 4 and 5) and the second embodiment (as shown in fig. 7 and 8), the lamp projection unit of the present invention may be provided with only one reflecting mirror 2, and may realize a high beam shape or a low beam shape by designing the curvature and curvature change rate of the incident surface 3a and the exit surface 3b of the lens 3.
In the third embodiment, as shown in fig. 10 and 11, the vehicle lamp projection unit of the present invention may be provided with two reflecting mirrors 2, and the reflecting surfaces 2a of the two reflecting mirrors 2 are disposed to face each other vertically, and each reflecting mirror 2 is provided with one light source 1. By the two light sources 1 emitting light at the same time, a combined light pattern of high beam and low beam can be obtained. For example, the reflecting surface of the lower reflecting mirror 1 in fig. 11 may be a high beam reflecting surface, which is shaped like a paraboloid, and has a far focus and a near focus, the light source 1 is disposed at the near focus, the far focus is disposed near the focus of the lens 3, the high beam illumination light shape can be realized by changing the light path of the light emitted from the corresponding light source 1 by the combination of the lower reflecting mirror 1 and the lens 3, and the high beam illumination light shape does not need a cut-off line, which is a common method of the conventional projection type car lamp system, but the conventional projection type car lamp system needs to be disposed near the focus of the lens to affect the high beam illumination light path, so that a reversible light shielding structure is often required, and the mechanism for switching the position of the light shielding structure inevitably causes the problems of complex car lamp structure, increased cost, easy wear of the mechanical structure, and the like by an electromagnetic valve or a motor. As shown in fig. 7 and 8, in the car light projection unit with the light shielding structure omitted, the light path of the light emitted by the corresponding light source 1 is changed through the combination of the reflector 2 and the lens 3 positioned above, so that the low beam illumination light shape can be realized, convenience can be provided for high beam illumination, and the switching between high beam and low beam can be realized only through the control of the on and off of the light source 1.
Of course, the number of the mirrors 2 arranged in such a vertically opposed manner is not limited to two, and a plurality of sets of the mirrors 2 arranged in a vertically opposed manner may be provided.
In the fourth embodiment, as shown in fig. 12, the lens 3 of the present invention may have a plurality of focuses, and all the focuses are located on the same focal line 3 c. Thus, there may be provided a plurality of mirrors 2, and the far focus F2 of all the mirrors 2 is located near the focal line 3c of the lens 3, for example, as shown in fig. 12, the mirrors 2 may be provided with three, and the three mirrors 2 are arranged in order along a track parallel to the focal line 3c of the lens 3, and the three mirrors 2 are located on the same plane. Each reflecting mirror 2 is correspondingly provided with one light source 1, so that light rays emitted by each light source 1 can be reflected by the corresponding reflecting mirror 2, converged near a focal line 3c of the lens 3, refracted once by an incident surface 3a of the lens 3 and refracted twice by an emergent surface 3b of the lens 3, and then irradiated to a road surface to form an illumination light shape. Of course, the number of the reflecting mirrors 2 in the present invention is not limited to three, and may be set according to the actually required illumination light shape.
In the fifth embodiment, as shown in fig. 13, there is another form in which three mirrors 2 are arranged in order according to the shape of the focal line 3c of the lens 3.
Therefore, the car light projection unit can be provided with the plurality of reflectors 2 and the corresponding light sources 1, so that the total luminous flux output by the light sources 1 can be effectively increased, the requirement of an illumination light shape on the irradiation range of a road surface can be met, and the brightness requirement of test points of different illumination functions can be met by regulations, so that the illumination functions are not required to be realized through the combination of the plurality of car light projection units, the car light structure can be greatly simplified, the space occupied by the car light projection unit is reduced, and the car light weight is reduced.
Based on the car light projection unit, the invention further provides a car light assembly, and the car light assembly comprises the car light projection unit.
Based on the car lamp assembly, the invention further provides a car, and the car lamp assembly comprises the car.
In summary, the vehicle lamp projection unit, the vehicle lamp assembly comprising the vehicle lamp projection unit and the vehicle comprising the vehicle lamp assembly control the light path of the incident light through the lens 3 to form the required illumination light shape. In addition, the car light projection unit can be provided with the plurality of reflectors 2 and the corresponding light sources 1, so that the total luminous flux output by the light sources 1 can be effectively increased, the requirement of the illumination light shape on the irradiation range of the road surface can be met, and the brightness requirement of the rule on test points of different illumination functions can also be met, so that the illumination functions are not required to be realized through the combination of the plurality of car light projection units, the car light structure can be greatly simplified, the space occupied by the car light projection unit is reduced, and the car light weight is reduced.
The foregoing is merely a preferred embodiment of the present invention, and it should be noted that modifications and substitutions can be made by those skilled in the art without departing from the technical principles of the present invention, and these modifications and substitutions should also be considered as being within the scope of the present invention.
