The invention relates to a positioning device, in particular to a non-
contact type positioning device for a lighting body capable of utilizing different color sequences, comprising a
light source device, a shooting
inductor, a
software and hardware device processed by the shooting
inductor, and connection
software which is connected with a terminal device and has corresponding communication and positioning functions, wherein the
light source device is a lighting source with two or more than two colors and can sequentially change a color
light source, the shooting
inductor is used for image interception with
fixed frequency in each second, each distinct image is taken by the shooting inductor, the
software and hardware device processed by the shooting inductor is used for judging if the light source device can sequentially change the color light source and the
light spot positions of the color light source and is also used for eliminating the interruption of other fixed light sources, and then the software and hardware device carries out
light spot coordinate operation, and then inputs
light spot coordinate values to the terminal device. The invention has the advantages that the non-
contact type positioning device eliminates the interruption by a changing light source when being compared with a fixed or changed
background color or other interrupting light sources and precisely positions the light source position, thereby having low cost and effectively preventing the environmental interruption.
