Lighting device

[0013]With reference to the drawings and in particular to FIG. 1, which shows a lighting device constructed in accordance with the present invention, generally designated with reference numeral 1, the lighting device 1 comprises a control circuit board 13 and a plurality of light-emitting diodes (LEDs) 12, the LEDs 12 being electrically connected to each other to form a circuit loop. In the embodiment illustrated, the LEDs 12 are mounted a substrate 11 having two power terminal contacts. The LEDs 12 mounted on the substrate 11 are further electrically connected to a the control circuit board 13, which comprises a control circuit that comprises a band switch 131 and that is preloaded with control data of multiple color lights in accordance with the characteristics of the LED chips.

[0014]Each LED 12 includes at least a red-light chip 121, a blue-light chip 122, and a green-light chip 123, as shown in FIG. 2. The LEDs 12 are connected to form a circuit that is electrically connected to th
