The flash lamp mentioned in this embodiment includes, but is not limited to, a traffic security proximity flash lamp, such as: xenon flash lamp.
The flash body 1 mentioned in the present embodiment may include a reflector 12, wherein the light source 11 may be a xenon lamp tube, and illustratively, the xenon lamp tube may be a spiral xenon lamp tube; the curved surface of the reflector 12 can be a paraboloid, a smooth surface or a segmented surface, and the reflector 12 is used for collimating light. The reflector 12 may be an aluminum material and plated with aluminum. The curved surface of the reflector 12 is not a standard paraboloid because the luminous surface of the xenon lamp tube is larger, the light type center is easy to slightly concave when the standard paraboloid is used, the light emitting can be effectively avoided when the standard paraboloid is used, and the sectional surface can enable the light emitting to be more uniform.
The whole surface of the grille part 2 may be coated with a layer of light absorbing material, which can absorb light striking the side wall, in this embodiment, the light-emitting channels 22 of the grille part 2 have a certain height, the longitudinal dimension of the light-entering opening 221 is larger, and at least part of the light-emitting openings 222 corresponding to the light-entering opening 221 have a smaller longitudinal dimension and are upward or are upward staggered, so that the light-emitting channels 22 can shade the light rays of the downward angle of the part 223. The light emitted by the xenon lamp tube is collimated by the reflector 12, limited by the size and the curved surface of the reflector 12, 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 part of the light, especially the light with a longitudinal downward angle, by the action of the grille part 2, and the license plate is arranged below the vehicle window position. As can be seen from fig. 8, 9, 13 and 14 (the light patterns of the two honeycomb gratings are similar), the lower limit of the longitudinal light emitting angle of the flashlight provided in this embodiment is cut off at 12 °, so that the license plate can be effectively prevented from being irradiated by excessive light under the snap-shot distance of about 4m from the entrance.
In summary, the flash lamp provided in this embodiment modulates the light spots through the grille part 2, so that an asymmetric light spot with a smaller longitudinal downward light emitting angle can be obtained, and when a camera matched with the flash lamp is used for capturing the face in a vehicle in a short distance, the license plate in the image is not overexposed.
The caliber and the curved surface of the reflector 12, the thickness of the grating part 2, and the shapes and the sizes of the light outlet 222 and the light inlet 221 of the light outlet channel 22 can be used as design variables, and the required light type cut-off angle can be designed according to the actual needs according to the information such as the distance of a use scene.
An image pickup apparatus provided in this embodiment includes any one of the flash lamps provided in the above-described technical scheme.
The image pickup apparatus provided in this embodiment includes the above-described flash lamp, and thus, at least the technical effects that the above-described flash lamp can achieve, that is, the light irradiated onto the license plate is reduced, the intensity of the light irradiated onto the license plate is reduced, and thus, the occurrence of overexposure of the license plate can be reduced or even avoided.
