Lamp dimmer using NE555 EasyEDA Lamp dimmer using NE555. This project is about simple lamp dimmer project using NE555 timer IC. PWM method is used for controlling the brightness of the lamp. This method is very power efficient and low cost compared to linear power control circuits. In PWM method the load is driven using a high frequency square wave and the duty cycle of this square wave is varied for controlling the power delivered to the load. PWM lamp dimmer using NE555_Circuit Diagram World PWM lamp dimmer. A simple and efficient PWM lamp dimmer using timer IC NE555 is discussed in this article. Yesterdays linear regulator based dimmers can only attain a maximum efficiency of 50% and are far inferior when compared to the PWM based dimmers which can hit well over 90% efficiency. PWM Lamp Dimmer using IC 555 Making Easy Circuits Overall, lamp dimmers based on PWM is more efficient when compared to the previous ones. The following diagram provides an elaborate sketch of 12V PWM lamp dimmer: Referring to the circuit design it is clear that IC timer NE555, which is the core of the system is wired into the circuit in the form astable multi vibrator. PWM Lamp Dimmer Using NE555 Timer instructables PWM Lamp Dimmer Using NE555 Timer: This is an engineering level project in which we use PWM to dim the intensity of the LED light. Here, the DC source is connected to NE555 timer. The PWM signal always depends on the duty cycle, so we can vary the duty cycle through NE555. If we va...
