UMP version LED bulb [electronic resource]

Subject(s):

Light-emitting diodes

Dissertation note: Project paper (Bachelor of Electrical Engineering (Electronics)) -- Universiti Malaysia Pahang - 2008 Abstract: The conventional bulb (incandescent and fluorescent) are considered as the only alternative right now to produce bright light, however bulb that use light-emitting diodes (LEDs) – which contain no mercury neither produce CO2 - are quickly emerging as a challenger. LED is the type of lighting, which is most commonly use to illuminate signs, signals and displays but is rapidly evolving to provide light for general illumination. This project is focusing to design and build UMP version LED bulb. It consist the module of the transformer, rectifier, battery backup and LED bulb. The transformer is used to step-down the AC voltage from the main supply and the output of the transformer will be rectified to DC voltage by the rectifier. The IC voltage regulator provides the desired supply to the LED bulb by limiting the current and voltage to avoid the LED bulb from damage. When power failure is occur in the system, battery backup will act as main supply to the LED bulb. The LED bulb consist several white LED which is grouped together to produce bright light.
