<p>An electronic flower lighting device with a multi-stage nature color is provided to obtain a vivid illuminating effect by changing colors from light color to dark color using plural combination circuits. A pulse generator(10) generates a pulse at a predetermined interval. A binary counter(12) generates a binary code of 4 bits whenever the pulse is inputted from the pulse generator. A combination circuit(14) combines digital signals outputted from the binary counter. An light emitting diode driver(16) drives a light emitting diode(18) outputting light corresponding to the signal outputted from the combination circuit. A lighting device emits light of double colors by combining upper and lower portions of the lighting device.</p> |
