Infrared remote control dimmer light circuit diagram

Description: This circuit utilizes the KA2184 infrared receiver ASIC for an infrared remote control dimmer light application, as depicted in the schematic. The infrared signal is generated by a pulse generator using an NE555 timer integrated circuit. The NE555 produces a 40kHz pulse that is amplified by a transistor (VT) and emitted through an infrared LED (SE303). For the design, various NE555 variants such as VA555, LM555, or SL555 can be employed. The KA2184 serves as the infrared transmitter, while the infrared receiver IC (IC2) is interchangeable with the CX20106, sharing identical performance parameters and pin functions. A standard small plastic package TRIAC, like the 1VIAC94A4 or MAC97A6, is recommended for VTH. For voltage regulation, a 12V, 0.5W silicon zener diode, such as the 2CW60-12V, 1N5242, 1N5242B, 1N6002, 2CW5242, or UZ-12B models, is suggested. Other components do not have specific requirements, and their selection can be referenced in the accompanying figure.

The KA2184 infrared receiver circuit operates by receiving modulated infrared signals emitted by the transmitter. The NE555 timer circuit generates a square wave signal at a frequency of 40kHz, which is suitable for infrared communication. This signal is amplified by the transistor (VT) to drive the infrared LED (SE303), which emits the modulated infrared light. The use of the NE555 allows for flexibility in the design, as multiple variants can be utilized without affecting the overall functionality of the circuit.

The KA2184 integrated circuit is specifically designed for infrared remote control applications, providing efficient signal processing capabilities. It is crucial to ensure that the infrared LED and the receiver are aligned properly to maintain effective communication. The interchangeable nature of the infrared receiver IC (CX20106) allows for easy upgrades or replacements without significant redesign.

The TRIAC (VTH) is employed to control the power delivered to the light source, allowing for dimming functionality. The choice of a small plastic package TRIAC ensures that the circuit remains compact and efficient. The selection of a zener diode (VS) rated at 12V and 0.5W is essential for voltage regulation, protecting the circuit from potential overvoltage conditions.
