For example, in the present embodiment, the extending portion 103d may constitute a reflecting cover for collecting light. Changing the radius of curvature of the reflecting surface 103e of the reflecting cover changes the focal length of the reflecting cover. The auxiliary light source illuminates the strongest position (light projection direction S), which will change with the distance between the light source and the focal length of the reflector (ie, defocus). The farther the light source is from the focal length, the position with the strongest light intensity will move backward from the second side 101b. In addition, different reflector designs can also be used to adjust the narrowness or width of the angular distribution of light. It is worth noting that the user can adjust the light projection direction S and the projection range of the light L according to the characteristics of different beverage foods 13 (or exhibits) to achieve the best display. quality. Therefore, the detailed adjustment range is not described here. An auxiliary light source device 102, including for providing Light-emitting or invisible light-emitting diode strips, cold-cathode tube strips or hot-cathode tube strips.
