An infrared emitter is an electronic component that emits infrared light.
Infrared is a type of electromagnetic wave naturally radiated by all objects that possess heat. It is also present in sunlight, and the warmth we feel from the sun corresponds to infrared radiation. An infrared emitter is a device that converts electrical energy into infrared light and intentionally releases it.
Infrared emitters using light-emitting diodes (LEDs) are common. Other types, such as halogen lamps and ceramic heaters, also exist and use heat sources to radiate infrared light.
Infrared light shares the properties of visible light and can be focused in a specific direction using lenses or reflectors. Since it is invisible to the human eye, it is especially useful in dark environments where illumination is unnecessary, making its applications highly diverse.
Infrared emitters are used in applications such as the following.
The most familiar example is the remote control used for televisions, air conditioners, and similar devices. An infrared emitter built into the tip of the remote flashes in specific patterns corresponding to commands, transmitting infrared light as a digital signal. The receiver in the main unit reads this light pattern, enabling remote operation. Infrared communication is widely adopted in many home appliances because the components are inexpensive, and the circuit configuration is simple.
Infrared emitters are also widely used in sensors that detect the presence of people or objects. Security motion sensors and automatic doors operate by detecting changes in the minute infrared radiation emitted by the human body. They are further applied in security cameras for nighttime or low-light surveillance. An infrared emitter illuminates the target object with infrared light, and an infrared camera captures the reflected light, enabling imaging of the object even in dark environments.
This application utilizes infrared's property of converting into heat when absorbed by materials. A representative product is the infrared heater. It employs radiant heating to warm objects without air transfer, resulting in high energy efficiency. Leveraging this characteristic, it is used in industrial fields for drying coatings and curing resins, and in agriculture for drying crops.
