PURPOSE: A decoration lamp is provided to show the dynamic or static shape according to the connected state of power and to be convenient in appreciation in the dynamic shape. CONSTITUTION: A decoration lamp is acted by: starting to generate heat from a structure(2) having a random shape if a switch is on to emit lights from an electric bulb(3); liquefying solid paraffin(6) by generating heat from the structure; recognizing the structure by making the liquefied paraffin transparent. Therefore, a chip(6a) in the paraffin shows the dynamic shape according to the movement of the paraffin if the liquefied paraffin is heated as much as the convection current occurs. A power switch is off by operating a sensor embedded in a bottom support(4) for a lamp and a circuit of a power feed unit after detecting the overheating with the sensor. The decoration lamp continuous operation to act as long as the switch is not off if the overheat is mot detected by the sensor. |
