PURPOSE: An awaking alarm apparatus is provided to lower energy consumption by the application of LEDs instead of an incandescent lamp and a fluorescent lamp. CONSTITUTION: A luminous unit(10) comprises multiple LEDs placed on the front side of a device body in the shape of round or matrix. The device body can be formed in the shape of round, ellipse, many-sidedness in consideration of outer appearance and design. Each LED is connected to a transistor for amplifying current to turn on each LED. Each transistor is connected to an AND gate(30). An AND gate is connected to a decoder(40). The decoder is connected to a control unit(50). The control unit connects to a real time clock IC unit(60), a display unit(70), and a keypad unit(80). A power supply unit(90) supplies power for turning on LEDs. |
