This project uses IR LEDs and sensors to switch the lights. It is because IR is cheap and much reliable in long range. The IR transmitter is made using IR LEDs, IC and resistors. It generates a 38 KHz IR radiation. The radiation starts producing when the light is switched ON. This IR radiation is transmitted and the receiver on the vehicle which is coming opposite with high beam picks up the radiation and the light in it is automatically dimmed. When the vehicle passes by, the bright bulb of this vehicle get switched back to ON. The IR receiver when receiving signal switches the bright bulb to dim bulb. We are switching between the light modes with IR radiation as a actuating signal. The switching is controlled by our smart AIMEE (Alternation using Infrared Module with Emission as an Extension) control. AIMEE control can effectively switch between the modes by judging the distance between the vehicles and switching between the modes and automatically turning back the bright lights after the passage of the vehicle.. The AIMEE module which we created acts as a brain for the lights to switch between the modes. We are planning to make to versions AIMEE(BrainBox) and AIMEE(Integrated)
This two-page document describes a student project called "IR Controlled Vehicle Headlamps." The project uses IR LEDs and sensors to switch vehicle lights between bright and dim modes. An IR transmitter built from IR LEDs, an IC and resistors generates a 38 kHz IR radiation; a receiver on an oncoming vehicle running high beam picks up the radiation, and that vehicle's bright bulb is automatically dimmed. When the vehicle passes, the bright bulb switches back on.
The switching is governed by the team's AIMEE (Alternation using Infrared Module with Emission as an Extension) control, which judges the distance between vehicles. Two versions are planned: AIMEE (BrainBox), a box with a connector port that is wired into existing vehicles, and AIMEE (Integrated), a headlight with the control system built in. The circuit uses a common 555 IC and a TSOP IC, with no microcontroller, and the document states the device can be fitted to two wheelers and four wheelers and works even in rainy conditions.
| IR carrier frequency | 38 kHz |

| Transmitter components | IR LEDs, IC and resistors |
| Integrated circuits used | 555 IC and TSOP IC |
| Microcontroller | None used |
| Weather conditions | Works well in rainy conditions |
| Vehicle types | Two wheelers and four wheelers |
The IR receiver on the oncoming vehicle picks up the transmitted IR radiation and switches its bright bulb to the dim bulb. After the vehicle passes, the bright bulb is switched back on.
The circuit uses the common 555 IC and a TSOP IC, with no microcontroller or complicated devices.
Yes. The AIMEE (BrainBox) version is a box with a connector port that existing lights and switches can be wired to according to its pin outs.
AIMEE (BrainBox) is a separate box containing the circuits that is wired into a current vehicle, while AIMEE (Integrated) is the team's own headlight with the AIMEE control system built in.
