Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.In the description, same or analogous drawing reference numeral represents same or analogous parts.The explanation of following reference accompanying drawing to embodiment of the present invention is intended to make an explanation to present general inventive concept of the present invention, and not should be understood to one restriction of the present invention.
Fig. 1 schematically shows the lighting system of the license plate lamp 100 according to one embodiment of the invention.License plate lamp 100 is positioned at the top of motor car license plate 200, sends illumination light 300 and throws light on to motor car license plate 200.Mark 12 typical positions on licence plate 200 in FIG, represented with the English alphabet a-l with circle respectively.By these typical positions, can test and assess the performances such as the uniformity of license plate lamp 100 pairs of licence plates illumination and brightness.For the situation that licence plate 200 is longer, as shown in Figure 1, two license plate lamp 100 combinations can be adopted to carry out throwing light on to make each position on licence plate 200 have enough illumination uniformities and brightness.But this not necessarily, such as, also can use one, three, a four or more license plate lamp 100 throws light on, those skilled in the art can select according to the quantity of requirement to license plate lamp 100 of illumination.
Fig. 2 shows a kind of example of license plate lamp as shown in Figure 1.This license plate lamp 100 comprises light source 101 and light distribution device 102.This light distribution device 102 is for adjusting the illumination light 300 of the licence plate 200 forming directive motor vehicles to the light beam 103 sent from light source 101.Described light distribution device 102 can have the luminous intensity distribution portion 104 for receiving and adjust the light beam 103 sent from light source 101, described luminous intensity distribution portion 104 central axis 106 substantially parallel relative to the light-emitting axis 105 of itself and light source 101 be 180 degree rotational symmetric.Revolve the shape after turnback by luminous intensity distribution portion 104 around its central axis 106 substantially to overlap with the shape in the luminous intensity distribution portion 104 do not rotated.Typically, central axis 106 is through the geometric center in luminous intensity distribution portion 104.Exemplarily, described luminous intensity distribution portion 104 can comprise optical surface.
Because the light distribution of the illumination light 300 penetrated from license plate lamp 100 determines primarily of luminous intensity distribution portion 104, therefore, for above-mentioned example arrangement, be arranged on two kinds of situations on vehicle again for being directly installed on by this license plate lamp 100 on motor vehicles and after revolving turnback, illumination light 300 will have substantially identical light distribution.This installation for license plate lamp 100 and manufacture are all useful.Such as, when needs two license plate lamps 100 throw light on symmetrically, if the luminous intensity distribution portion 104 of license plate lamp 100 is not rotational symmetric as mentioned above, then needs to consider installation direction problem, otherwise the illuminating effect of expectation may not be realized.Again such as, when installing the license plate lamp being used for licence plate and tail licence plate before motor vehicles, having is not that the license plate lamp in rotational symmetric luminous intensity distribution portion described above also may exist specific installation direction problem.If installation direction is inconsistent, often may causes in practice needing the different parts of making two kinds to meet the demand of system, which results in the rising of manufacturing cost.And adopting 180 degree of rotational symmetric luminous intensity distribution portions 104 as above, license plate lamp 100 can obtain substantially identical light distribution when rotation 0 degree with installing when revolving turnback, therefore, does not need the problem considering installation direction.Avoiding problems unnecessary installation and manufacturing cost.
Exemplarily, license plate lamp 100 can also comprise lamp housing 107, for holding light source 101 and light distribution device 102.Light distribution device 102 can also comprise support portion 102a, and described support portion 102a is for supporting luminous intensity distribution portion 104 and fixing with lamp housing 107.Such as, light source 101 can be carried by light source base 1011.
In one example, the illumination light 300 sent to make license plate lamp 100 can obtain evenly light intensity, luminous intensity distribution portion 104 can the vicissitudinous curvature of tool.In other words, the curvature of the various piece in luminous intensity distribution portion 104 can be inconsistent.The curvature in such as luminous intensity distribution portion 104 can be change on first axle direction, light-emitting axis 105 perpendicular of this first axle direction and light source 101.When license plate lamp 100 is installed on the rolling stock, the travel direction perpendicular of described first axle and motor vehicles.Due to the schematic cross sectional views that Fig. 2 is in the vertical plane perpendicular to motor vehicles travel direction, so the direction of first axle is left and right directions in fig. 2, as shown in the X-axis line in Fig. 2.The curvature in luminous intensity distribution portion 104 also can be change on the second axis direction, and described second axis direction is all vertical with described first axle with the light-emitting axis 105 of light source 101.Due to the schematic cross sectional views that Fig. 3 is in the vertical plane being parallel to motor vehicles travel direction, so the direction of the second axis is left and right directions in figure 3, as shown in the Y-axis line in Fig. 3.Exemplarily, the curvature in luminous intensity distribution portion 104 also all can change on first axle direction and the second axis direction.By means of the luminous intensity distribution portion 104 of the vicissitudinous curvature of tool, the illuminating effect of license plate lamp can be improved, such as, can increase the illumination zone of license plate lamp, reduce the luminance difference etc. between different parts on licence plate.
Fig. 6 gives the top view in the luminous intensity distribution portion 104 according to one embodiment of the invention.Can clearly be seen that from Fig. 6, luminous intensity distribution portion 104 is divided into multiple first axial subarea 1041 along first axle direction (X-axis line), and two adjacent the first axial subareas 1041 in described multiple first axial subarea 1041 have different curvature on first axle direction.The first axial subarea 1041 with different curvature can adjust the light distribution of illumination light 300, is especially distributed to region (corner) relatively dark on licence plate to make illumination intensity distribution more even to improve optical efficiency by concentrating on the illumination intensity at some position on licence plate.This is especially useful when licence plate is relatively grown.
Exemplarily, as shown in Figure 6, the first axial subarea 1041 can be the banded regions extended along the second axis direction.The different position that each banded regions can correspond respectively on licence plate to be illuminated is designed.For the situation of Shuangpai County's illuminator illumination shown in Fig. 1, the luminous intensity distribution portion 104 of such as, light distribution device 102 in the license plate lamp 100 on the left side has multiple first axial subareas 1041 as shown in Figure 6, then can by being designed to send from light source 101 from first the first axial subarea 1a of left number and being irradiated to the upper left corner area (as shown in Figure 1 a region) of the light guiding it to licence plate shown in Fig. 6, second the first axial subarea 1b from left number is designed to send from light source 101 and is irradiated to the left area (as shown in Figure 1 a region and g region) of the light guiding on it to licence plate, by the 3rd and the 4th the first axial subarea 1c from left number, 1d is designed to send from light source 101 and the light be irradiated on it guides to partially middle region (b region as shown in Figure 1 and h region), the left side of licence plate, the 5th the first axial subarea 1e from left number is designed to send from light source 101 and is irradiated to the partially middle lower area (as shown in Figure 1 i region) of the light guiding on it to licence plate, the 6th the first axial subarea 1f from left number is designed to send from light source 101 and is irradiated to the partially middle upper area (as shown in Figure 1 c region) of the light guiding on it to licence plate.By means of above-mentioned design, the regional on the left side of licence plate is all assigned with light intensity, and this is easy to the uniformity and the raising optical efficiency that ensure illumination.But above-mentioned design is only exemplary, each first axial subarea 1041 is not limited thereto with the corresponding relation at each position on licence plate, can change according to the requirement of design or exchange, and, the number in the region of the licence plate to be illuminated corresponding to each first axial subarea 1041 also can change, such as also can be corresponding with a, c and g tri-regions on licence plate for second the first axial subarea 1b.
