Our Product
Manual, automatic control of lights
Automatically control lights according to room occupancy,
programmed alarms
Energy efficient
Cost: $300 for control panel, $213 for light bulb
Two components
 Control
panel module
 Backlit
LCD, pushbuttons, speaker, occupancy sensor
 Alarm clock functionality
 Standard electrical outlet
 Light
 Standard
light sockets
Wireless communication
LED power supply is too long
 Solution:
UART not working correctly between PIC
microcontroller and ZigBee antenna
 Solution:
Cut it in half
Set PIC’s low voltage programming OFF
LEDs overheat
 Solution:
Use better heat sink or run LEDs at < 200mA
Technical Specifications
Control Panel Unit:
Functions as Alarm Clock
 Consumes low power (< 5W)
Light Bulb Unit:
Uses at least four high power LEDS
 Reduces power consumption through switching power
supplies (<15W)
 Dims LEDs through PWM (0 to 1.5W)
