Example one
Referring to fig. 1 to 3, the present application provides a license plate lamp device for illuminating a license plate 102 disposed thereunder. The license plate lamp device comprises a light emitting piece and a light homogenizing piece.
The light-emitting part comprises a plurality of light source parts 101, the light source parts 101 are specifically LED lamps, and the light source parts 101 are uniformly distributed along the length direction of the license plate 102 so as to illuminate the license plate 102. The light source 101 forms a radial light beam, which generates a dark area when illuminating the license plate 102. According to the license plate number identification device, a plurality of light sources are arranged to illuminate the license plate 102 together, namely, the density of the light source arrangement is increased, so that dark areas formed on the license plate 102 are reduced, the uniformity of illumination is improved, and the license plate 102 number can be conveniently identified in environments with poor light such as night.
Because the light source elements 101 form radial light beams, a dark area is formed on the license plate 102 by two adjacent light source elements 101, and in order to reduce the dark area formed on the license plate 102 by two adjacent light source elements 101, a light equalizing element is further arranged and used for reflecting light rays emitted by the light source elements 101 to all parts of the display area of the license plate 102. Specifically, the light source 101 forms a radial light beam to irradiate all around, and for the light far away from the license plate 102, the light equalizing member can reflect the part of light to the license plate 102, so that the brightness of the license plate 102 is improved, and the dark area on the license plate 102 is further eliminated.
The application provides a license plate lamp device is through setting up even light and a plurality of light source 101 to light reflection that light source 101 sent is everywhere to license plate 102's display area, and light can be even hits on license plate 102, and the people's eye of being convenient for is to the recognition of license plate number, and has promoted the pleasing to the eye degree of license plate 102 department.
In an optional scheme of this embodiment, the light-equalizing member is specifically a prism 103, the prism 103 is formed with a light-equalizing reflecting surface 104, and the light-equalizing reflecting surface 104 is used for reflecting light rays emitted by the plurality of light source members 101 to the license plate 102.
As shown in fig. 1, the light-equalizing reflective surface 104 includes a first reflective surface 105 and a second reflective surface 106 connected to each other, where the first reflective surface 105 is a top surface of the prism 103, and the second reflective surface 106 is a side surface of the prism 103 away from the light-emitting member; the first reflecting surface 105 and the second reflecting surface 106 form a predetermined included angle (angle α shown in fig. 1) which is greater than 90 degrees and less than 180 degrees.
In this embodiment, the light-equalizing reflective surface 104 is disposed at least in such a range that the reflected light can cover the entire display area of the license plate 102. Specifically, the light equalizing reflecting surface 104 includes a first reflecting surface 105 and a second reflecting surface 106 with a predetermined included angle, and the two reflecting surfaces can reduce the volume of the prism 103, for example, if only one reflecting surface is provided, in order to make the light cover the whole display area of the license plate 102, the volume of the prism 103 will be larger, which is not beneficial to the miniaturization of the vehicle device.
Referring to fig. 1, the license plate 102 is disposed obliquely, and light reflected by the first reflecting surface 105 and capable of striking the top of the license plate 102 (the leftmost dotted line in the figure, and the dotted line corresponding to the dotted line is the normal line corresponding to the light) and light reflected by the second reflecting surface 106 and capable of striking the bottom of the license plate 102 (the rightmost dotted line in the figure, and the dotted line corresponding to the dotted line is the normal line corresponding to the light) are shown, and a light beam between the two shown light beams can strike the whole display area of the license plate 102.
