Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
It should be noted that, in the following description, for example, "up", "down", "left", "right", "front", "back", and the like, refer to the directions of the high beam illumination system when applied to a vehicle, and the like have meanings derived from the directions of the front and the back, for example, according to the driving habits of our country, the direction of the driver seat is left, the direction of the front passenger seat is right, the direction of the roof is up, and the direction of the wheels is down. The "light emitting direction" is the irradiation direction of the light emitting rays of the high beam illumination system, and can be set according to the illumination function of the vehicle lamp to be realized, for example, the light emitting direction of the high beam vehicle lamp points to the front of the vehicle, and the light emitting direction of the corner lamp points to the outer side of the vehicle in an inclined manner.
Furthermore, the terms "first", "second" … … "eight" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicit indication of the number of technical features indicated, and therefore, the features defined by "first", "second" … … "eight" may explicitly or implicitly include one or more of the features described.
Hereinafter, the optical axis direction of the light source is the normal direction of the geometric center of the light emitting surface of the light source, and the optical axis of the lens is an axis passing through the focal point of the lens and extending back and forth along the light emitting direction of the lens.
The high beam illumination system of the invention comprises a plurality of light sources 1 and a plurality of collimating lens parts, wherein a plurality of collimating lenses are formed on the collimating lens parts, the collimating lenses on the collimating lens parts are in one-to-one correspondence, the plurality of collimating lenses in one-to-one correspondence and the light sources 1 corresponding to the collimating lenses form an optical unit, one optical unit comprises at least one light source 1, the optical axis of at least one collimating lens in the plurality of collimating lenses in one-to-one correspondence of at least one optical unit can be deviated relative to the optical axis of one of the light sources 1 corresponding to the collimating lens, so that the illumination spots formed by the projection of the light rays emitted by the light source 1 through the corresponding collimating lenses are deviated, the overlapping degree of the illumination spots can be adjusted through the deviation, and the number of the illumination spots overlapped in the middle area of the illumination light shapes is large, the number of the overlapped illumination light spots in the two side areas is small, so that the overlapped illumination light spots can form an illumination light shape with bright middle and dark two sides.
Specifically, when the optical unit includes one light source 1, the following three types of arrangements of the collimating lens and the light source 1 in the optical unit are provided: (1) the optical axes of the collimating lenses corresponding to one are offset relative to the optical axis of the light source 1; (2) the optical axis of part of the collimating lens is deviated relative to the optical axis of the light source 1, and the optical axes of the other collimating lenses are superposed with the optical axis of the light source 1; (3) the optical axes of the collimating lenses in one-to-one correspondence coincide with the optical axis of the light source 1.
When the optical unit comprises a plurality of light sources 1, the arrangement form of the collimating lens and the light source 1 in the optical unit can also have the three forms mentioned above by taking the optical axis of one of the light sources 1 as a reference, and the other light sources 1 in the optical unit are adaptively arranged near the light source 1.
The forms of the plurality of optical units in the high-beam illumination system of the present invention may be combined in any form or in a single form except for the form (3).
The focus of the collimating lens is located on or near the light emitting surface of the light source 1 corresponding to the collimating lens, and is preferably located at the center of the light emitting surface of the light source 1, so that the light emitted by the light source 1 can be projected into an illumination spot through the collimating lens corresponding to the collimating lens. Specifically, the collimating lens is a plano-convex lens, a hyperbolic lens or a cylindrical lens, and the collimating lens on one collimating lens portion may be any one of the above lenses, but since the cylindrical lens can only converge light in one direction, the combination of the collimating lenses in each optical unit only needs to meet the requirement of converging light in the upper, lower, left and right directions, and all the collimating lenses are prevented from adopting cylindrical lenses extending in the same direction.
Based on the technical scheme, each light source 1 can be fully turned on at full power, the number of the superposed lighting spots in the middle area is large, the number of the superposed lighting spots in the large-angle areas (the areas on two sides) is small, the lighting light shapes of the car lamp with bright middle and dark two sides are realized, the lighting requirements of the car lamp are met, and the formation of dark areas among the lighting spots is also avoided.
In a special case, the illumination spots formed by the projection of adjacent light sources 1 may even be completely superimposed, further improving the brightness of the intermediate light shape.
In order to ensure the relative position precision between the collimating lenses and reduce the positioning and mounting errors, all the collimating lens parts are integrally formed parts. Of course, a separate structure may be adopted as necessary.
According to different requirements of a customer on the appearance shape of the car lamp, the projection shape of the light-emitting surface of the collimating lens positioned at the forefront in the optical unit is square, circular, rhombic, trapezoidal, parallelogram or triangular, and compared with the prior art in which only one monotone-shaped lens is adopted, the appearance shape is more attractive and more flexible.
As an embodiment of the present invention, the optical axis of the collimating lens is shifted in different directions from the optical axis of the corresponding one of the light sources 1. The optical axis of the collimating lens is offset with respect to the optical axis of the corresponding one of the light sources 1 by different distances. The larger the offset distance of the optical axis of the collimating lens from the optical axis of the corresponding one of the light sources 1 is, the larger the offset angle of the corresponding illumination spot is, and at this time, the collimating lens is preferably a plano-convex lens. It should be noted that both the illumination spot and the illumination light shape refer to light shapes of light projected on the light distribution screen, and since the light rays all have divergent angles, the positions of the light shapes on the light distribution screen are also calibrated by angles.
In order to facilitate heat dissipation, the light sources 1 are dispersedly mounted on the circuit board and fixed on the heat sink 4.
In the process of processing and mounting, the size and the brightness of a single illumination spot can be adjusted by adjusting the distance between the light source 1 and each collimating lens part in the optical axis direction. For example, some vehicle-type vehicle lamps need large light spots and high brightness, the distance between the collimating lens parts can be processed to be smaller, and the distance between the collimating lens parts and the light source 1 is smaller in the installation process; the vehicle lamp of some vehicle types does not need large light spots and high brightness, the distance between the collimating lens parts can be processed to be larger, and the distance between the collimating lens parts and the light source 1 is also larger in the installation process. Namely, the invention can produce products with various specifications according to the requirements.
In order to realize the adaptive high beam function and prevent the illumination light from dazzling the front or the opposite vehicle or the pedestrian, each light source 1 is adapted to be independently switched, so that when the vehicle or the pedestrian exists in the front of the vehicle or the opposite side, the corresponding light source 1 is switched off to change the corresponding illumination area into a dark area.
A second aspect of the invention provides a vehicular lamp including the high beam illumination system described above.
As can be seen from the above description, the present invention has the following advantages: the overlapping degree of the lighting light spots is adjusted through the relative deviation of the optical axes of the optical elements in the optical unit, so that the number of the lighting light spots overlapped in the middle area of the lighting light shapes is large, the number of the lighting light spots overlapped in the areas on two sides is small, the lighting light shapes of the car lamp with bright middle and dark two sides are realized, and meanwhile, the light shapes are uniformly transited, and the generation of dark areas is avoided; in the preferred scheme of the invention, the larger the offset distance of the optical axis is, the larger the offset angle of the illumination light spot is, the simpler the setting method is compared with other modes, and on the premise of realizing the purpose that the middle of the integral illumination light shape is bright and the two sides are dark, the labor intensity of designers can be reduced; in the preferred scheme of the invention, the collimating lens parts are all integrally formed parts, so that the relative position precision between the collimating lenses is ensured, the positioning and mounting errors are reduced, and a good light shape effect is further obtained; further, the size and brightness of the light shape can be adjusted by adjusting the distance between the light source 1 and each collimator lens section in the optical axis direction.
The following is a preferred embodiment of the present invention.
Referring to fig. 1 to 7, the high beam illumination system of the present invention includes a plurality of light sources 1, a plurality of primary collimating lenses 2 located on the same collimating lens portion, and a plurality of secondary collimating lenses 3 located on the same collimating lens portion, wherein the plurality of light sources 1 are arranged in an array, and the light sources 1, the primary collimating lenses 2, and the secondary collimating lenses 3 are in one-to-one correspondence and are sequentially arranged along a light emitting direction; wherein the optical axes of three of one or more of the light sources 1, their corresponding primary collimating lens 2 and the secondary collimating lens 3 coincide to project to form one or more illumination spots located at or near the middle of the illumination light pattern. The optical axes of the rest of the light sources 1, the corresponding primary collimating lens 2 and the secondary collimating lens 3 are coincident, and the optical axis of the third one is offset relative to the two coincident optical axes, so as to project and form an illumination spot offset relative to the illumination spot located at or near the middle position of the illumination light shape. For example, the optical axis of the light source 1 and the optical axis of the secondary collimator lens 3 coincide with each other, and the optical axis of the primary collimator lens 2 is relatively shifted, or the optical axis of the primary collimator lens 2 and the optical axis of the secondary collimator lens 3 coincide with each other, and the optical axis of the light source 1 is relatively shifted, or the optical axis of the light source 1 and the optical axis of the primary collimator lens 2 coincide with each other, and the optical axis of the secondary collimator lens 3 is relatively shifted.

For example, the light source 1 above the light source 1 with the three optical axes coinciding is upwardly offset with respect to the primary collimating lens 2 and the secondary collimating lens 3 correspondingly disposed thereon, the light source 1 below the light source 1 with the three optical axes coinciding is downwardly offset with respect to the primary collimating lens 2 and the secondary collimating lens 3 correspondingly disposed thereon, the offset distance of the light source 1 close to the light source 1 with the three optical axes coinciding is small, the offset distance of the light source 1 far from the light source 1 with the three optical axes coinciding is large, and in any way, the final goal is to make the whole illumination light shape bright in the middle and dark at both sides. Preferably, the optical axis of the light source 1, the primary collimating lens 2 and the secondary collimating lens 3 which coincide with each other farther from the optical axis, is offset by a larger distance with respect to the optical axis of the light source 1, the primary collimating lens 2 and the secondary collimating lens 3.
As a further preferred embodiment of the present invention, the high beam illumination system includes a heat sink 4, a circuit board mounted on the heat sink 4, eight light sources 1 arrayed on the circuit board, and primary collimating lenses 2 and secondary collimating lenses 3 corresponding to the eight light sources 1 one by one, respectively, i.e., eight primary collimating lenses 2 and eight secondary collimating lenses 3, respectively. As shown in fig. 4-6, the optical axes of the first light source 11 and the corresponding first primary collimating lens 21 and second primary collimating lens 31 are overlapped, and the projected illumination spots are as shown in fig. 8; the optical axes of the other corresponding second to eighth primary collimating lenses 2 and the corresponding light sources 1 are respectively overlapped, that is, in order to ensure that the appearances of the eight secondary collimating lenses 3 serving as light emitting lenses are kept unchanged, the illumination light shapes with bright middle and dark two sides can be obtained by offsetting the optical axes of the light sources 1 and the primary collimating lenses 2 positioned inside relative to the optical axes of the corresponding secondary collimating lenses 3, specifically, the optical axis of the second light source 12 is offset to the right by 0.5mm relative to the optical axis of the corresponding second secondary collimating lens 32, and the illumination light spots formed by projection are as shown in fig. 9; the optical axis of light source No. three 13 is shifted by 1mm to the right with respect to the optical axis of its corresponding secondary collimating lens No. three 33, the illumination spot formed by its projection is shown in fig. 10, the optical axis of light source No. four 14 is shifted by 0.5mm downward with respect to the optical axis of its corresponding secondary collimating lens No. four 34, the illumination spot formed by its projection is shown in fig. 11, the optical axis of light source No. five 15 is shifted by 0.5mm to the left with respect to the optical axis of its corresponding secondary collimating lens No. five 35, the illumination spot formed by its projection is shown in fig. 12, the optical axis of light source No. six 16 is shifted by 1mm to the left with respect to the optical axis of its corresponding secondary collimating lens No. six 36, the illumination spot formed by its projection is shown in fig. 13, the optical axis of light source No. seven 17 is shifted by 1mm to the left with respect to the optical axis of its corresponding secondary collimating lens No. seven 37, the illumination spot formed by its projection is shown in fig. 14, the optical, the projected illumination spot is shown in fig. 15.
