It is also possible to adopt a configuration in which the arc tube 10 is integrally disposed along the inside or outside of the tube. After the end of the arc tube 10 in the installed state is bent downward, if it is necessary to be bent again in a different direction, it is bent and deformed as it is The shape can be freely set and the bent state can be reliably maintained, and even if the installation and withdrawal of the apparatus are repeated, the end of each tube is kept downward, so that a state in which water droplets do not occur in the tube can always be ensured. Replace Requirements can be used in a variety of places over a long period of time without.
[0025]
Further, in the fireworks type illumination device according to the embodiment, the luminous body 11 in the luminous tube 10 is not limited to a luminous body that emits only monochromatic light of a general predetermined color, but can emit light by switching a plurality of colors by one. An LED or the like may be used to change the color at a predetermined timing and emit light under the control of the control unit 40.
