Infrared communication module with remote control transmission function
An infrared communication module with remote control function includes a PD chip for IrDA data, an IC chip, an LED chip for IrDA data, and an LED chip for remote control transmission that are mounted on a PWB. The PD chip, IC chip and LED chips are sealed by a resin. The resin forms a light-receiving lens for infrared communication surrounding the PD chip, a light-emitting lens for infrared communication surrounding the LED chip for IrDA data, and a light-emitting lens for remote control surrounding the LED chip for remote control transmission. Such a structure allows an infrared communication module with remote control transmission function having a structure that can prevent increase in the cost of production and a mounting space.
