| الملخص: | This paper presents the emergency lighting system using high intensity light emitting diode (LEDs) driven by the dc-dc boost converter. The objectives are to provide an energy saving, low power consumption and longer durability of emergency light compare to the conventional fluorescent emergency light. The proposed emergency lighting system is a combination of dc-dc boost converter and charger circuits. It is controlled by automatic switch to operate the light when main supply is disrupted. Low voltage application, 6V, 2.8AH lead acid battery is used as the supply voltage to 12V LEDs light. The prototype for LEDs emergency light using boost converter was developed. Experimental results show that the prototype emergency lighting system luminous intensity can reach to 25 lux with 3 meters from the lux meter location and it can reach 4 hours of operation. The prototype is comply with the IEEE std 446-1995 requirement. |
