PURPOSE: A multidirectional illuminating device with a high luminance LED(Light Emitting Diode) is provided to adjust brightness and lighting hour without error by supplying stable voltage to circuits and transmitting a synchronous signal to a microprocessing unit. CONSTITUTION: A PCB(printed circuit board)(14) is installed in a PCB slot(15), and plural high brightness red, green, blue LEDs(11,12,13) are arranged on the PCB. Plural LEDs on the PCB are switched on and off sequentially according to the established order by a microprocessing unit. The stable voltage is supplied to each circuit, and an outer synchronous signal is transmitted to the microprocessing unit. The brightness and lighting hours are adjusted without errors for various effects. The illuminator lights multidirectionally at the same time by inserting the PCB to the PCB slot for facing the LED outward. The life span is lengthened with a low heating LED, and the lighting apparatus is used conveniently by replacing the PCB at the LED failure. |
