The invention discloses a suspension columnar luminescent system based on the tensegrity principle. At present, no luminescent system in a suspension columnar appearance exists. The suspension columnar luminescent system is formed by overlaying a plurality of basic units in the vertical direction. Each basic unit comprises n luminescent tubes and 3n-7n inhaul cables, wherein n is not less than 3. The luminescent tubes of each basic unit are distributed in a dispersed mode, have no direct relation to one another and make no direct contact with one another. The inhaul cables of each basic unit are distributed continuously and connected with one another to constitute a closed network, and the inhaul cables can directly serve as conductive wires or supports of the conductive wires. All the luminescent tubes have definite pre-loaded pressure, all the inhaul cables have definite pretension force, and the pretension force of the inhaul cable is balanced with the pre-loaded pressure of the luminescent tubes. The luminescent tubes can be objects in any shape, wherein the objects can emit light after being powered on or can emit light by themselves, and all the luminescent tubes are arranged as if the luminescent tubes are suspended in the air and distributed in a cylinder shape. The suspension columnar luminescent system can be used in the fields such as buildings, sculptures, decorations and lamps.
