BACKGROUND OF THE INVENTION  
         [0001]    1. Field of the Invention  
           [0002]    The present invention relates to a multi-casing light-emission device, especially to a light-emission device having a plurality of casings, wherein a plurality of light-emitters are series connected, parallel connected, or series-parallel connected and are disposed internally in order to accomplish a brand-new light-emission effect.  
           [0003]    2. Description of the Prior Art  
           [0004]    Various models shaped as tigers, horses, leopards are usually used for displaying on general festivals or celebrations. As the models are displayed mostly at night (such as the festive lanterns on the Chinese Lantern Festival during the Lunar New Year), lights are required inside the animal-shaped models, so as to lighten and brighten the models.  
           [0005]    As conventions, the models are displayed as various appearances by using light-bulb strings, wherein the light bulbs are fixed so simply that the light-bulb holders are formed firstly and then the light bulbs are tied thereon. Consequently, bad stability is obtained, and it is time-consuming for installing the light bulbs; moreover, it is dangerous that the light bulbs are easily to be loosened. Thus, it is restricted that it was only suitable for static display.  
           [0006]    Alternatively, in some certain decoration models, long strings formed of independent light bulbs or LEDs that are series-connected are needed; thus, the fabrication cost is increased, and it is disadvantageous and very inconvenient to be disposed independently and stored wholly.  
           [0007]    In consequence, the present invention is generated after being tested and improved repeatedly by the inventor of the present invention who had studied and focused on the above-mentioned situations.
