The flash light mentioned in this embodiment includes but is not limited to traffic security close range flash light, for example: a xenon flash lamp.
The flash lamp body 1 mentioned in the present embodiment may include a light reflecting bowl 12, wherein the light source 11 may be a xenon lamp tube, and exemplarily, the xenon lamp tube may be a spiral xenon lamp tube; the curved surface of the light reflecting bowl 12 can be a paraboloid-like surface, and can also be a smooth surface or a segmented surface, and the light reflecting bowl 12 is used for collimating light. The reflector 12 may be aluminum and plated with aluminum. The curved surface of the reflector 12 is not a standard paraboloid because the light emitting surface of the xenon lamp tube is larger, the light type center is easy to be slightly sunken by using the standard paraboloid, the similar paraboloid can be effectively avoided, and the light emitting can be more uniform by the sectional surface.
The whole surface of the grid part 2 can be coated with a layer of light absorbing material, the light absorbing material can absorb light rays striking the side wall, in the embodiment, the light outlet channels 22 of the grid part 2 have a certain height, the longitudinal size of the light inlet 221 is large, and at least part of the light inlet 222 corresponding to the light inlet 221 is small and upward, or is staggered upwards, so that the light outlet channels 22 can shield 223 part of the light rays with downward angles. The light emitted by the xenon lamp tube is collimated by the reflector 12, is limited by the size and the curved surface of the reflector 12, still has a certain smaller light-emitting angle (for example, the light-emitting angle is 10-25 degrees when the light-emitting intensity is 50%), and can absorb partial light, especially the light with a longitudinal downward angle under the action of the grating part 2, and the license plate is arranged below the position of the vehicle window. As can be seen from fig. 8, 9, 13 and 14 (the light patterns of the two kinds of honeycomb grids are similar), the lower limit of the longitudinal light-emitting angle of the flashlight provided by the embodiment is cut off at 12 °, so that under a capturing distance of about 4m from the entrance and exit, excessive light can be effectively prevented from irradiating the license plate.
In summary, the flash lamp provided by the embodiment modulates the light spot through the grating portion 2, so that the asymmetric light spot with a smaller longitudinal downward light-emitting angle can be obtained, and when the camera collocated with the flash lamp captures the face of the person in the vehicle in a short distance, the license plate in the image is not over exposed.

The imaging apparatus provided in the present embodiment includes any one of the flash lamps provided in the above-described technical solutions.
The image pickup apparatus provided by the embodiment includes the flash lamp, so that the technical effects that the flash lamp can achieve at least can be achieved, that is, the light irradiated on the license plate is reduced, the intensity of the light irradiated on the license plate is reduced, and the occurrence of the license plate overexposure can be reduced or even avoided.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
