As described in the background art, the conventional dynamic imaging tool only uses the LCD liquid crystal screen to play dynamic video (or image), but since the liquid crystal screen itself does not emit light, a backlight lamp is required to be added to display the image. For example, as shown in fig. 1, in the structure of the existing LCD panel, light tubes are added at the rear two sides of the LCD panel, and then the backlight plate is used to uniformly disperse the light, thereby achieving the effect of playing dynamic video. However, the light intensity generated by the lamp tube behind the liquid crystal display is weak, and thus the requirement of illumination cannot be met, and therefore an ideal illumination effect cannot be achieved. In addition, the light intensity of the light tube of the current liquid crystal display cannot be changed, and the emitted light can stimulate eyes, so that dizziness, visual fatigue and the like can be generated when a played video (or a dynamic image) is watched.

In view of this, the utility model provides a lamps and lanterns for dynamic imaging, it can satisfy the illumination demand and can show good dynamic effect again.
