Abstract
A rear-end collision alarm apparatus featuring remote alarming is provided, including an alert detector device and an alert receiver device. The alert detector device is mounted on a preset warning object (such as a warning triangle and a cone). The alert receiver device is worn on or carried by a user. The alert detector device includes a first light source module, an infrared detection module, and a first Bluetooth module. The alert detector device is placeable, together with the warning object, at a predetermined remote distance from a traffic accident or construction site, where the first light source module may serve as a warning through light flashing. When the infrared detection module detects an object entering a detection range, the alert detector device transmits an alert signal through the first Bluetooth module to the alert receiver device to have the alert receiver device instantaneously emit alarming light and alarming sounds.
