A Project on Construction of Light Dimmer

ABSTRACT: This research work is a project on construction of light dimmer. The Light Dimmer Circuit was constructed by the use of traic: a bidirectional trigger diodes which has a break-over rating of 28v to 36v in either direction. Electronic equipment’s are now being unduly used they range from the telephone set through the radio receiver to the computer system. They are used in various ways as can be seen in the chapter four of this work. Light Dimmer can be used in residential homes for dimming filament bulbs not greater than 60 watt connected in series or parallel. It can also be applied in industries for controlling of an electric drill or speed of an electric motor or also used as heat control system.

A Project on Construction of Light Dimmer

It can be seen that our comfort and economy derives much benefits from the light dimmer. This paper therefore tries to bring the processes and where dimmer involved. The advantage is to maintain the component which made up the circuit, it can be easily replace when the system stop functioning to it accedes. This has been the one in a firmly simple straight forward manner without involving the aspect of mathematics.

CHAPTER ONE

GENERAL INTRODUCTION CONCEPT /COMPONENT USED

I.1  INTRODUCTION CONCEPT:

Light Dimmer is an electrical device used in various residential homes theater (Stage lighting). The Dimmer is controlled by a switching circuit is an electronic device, comprising of a triac, two resistor, two capacitors and a variable resistor, lamp holder and bulb.

The construction pattern and the operation of each component in the as well as the graphic symbols including the circuit diagram, schematic diagram and characteristic curve are applied.

Apart from dimming the filament (amps, the circuit can also control the of any electric motor and other land operated with alternating This is mainly for current ratio less than IA.

 

COMPONENT USED

TRAIC: Triac is a three terminal device for the control of alternating in either direction. It is similar to thyristor except that it can turn either plenty voltage applied and with either directions of gate current in both cases.

Since traic can conduct in either direction, it is not normally used as a rectifier The graphic symbol for triac and its characteristic curve is shown below in figure 1.2a and 1.216 respectively.
