Abstract

The invention discloses a solar roadblock warning device, in particular to a variable-frequency LED strobe warning device, which comprises a solar panel, a charge controller, a storage battery, a control circuit, and a lamp body. The control circuit is arranged inside the lamp body and comprises a power switching circuit, a singlechip control circuit, a toggle switch, a sensing module, and a driving circuit; and the lamp body consists of super red, yellow and blue LEDs, a lamp shell, and a lamp cover. The variable-frequency LED strobe warning device has the advantages that: by acquiring surrounding environment information, the device can automatically adjust the flicker frequency; through manual adjustment, the frequency can be set in a certain fixed value, so that the warning function has more pertinence; and due to the adoption of an integrated design and a solar power supply, the device is convenient, practical, energy-saving, and environment-friendly.

Description

technical field [0001] The invention discloses a solar roadblock warning device, in particular to a frequency-variable stroboscopic warning device. Background technique [0002] In highways, traffic intersections, accident-prone sections, construction sites, etc., it is often necessary to set up warning lights to remind passing vehicles and pedestrians to pay attention to safety. The frequency of the existing stroboscopic warning device is fixed, and the stroboscopic frequency cannot be adjusted according to specific needs. When an emergency occurs, the warning effect cannot be improved by changing the flashing frequency of the warning lights; in the case of poor visibility such as night or bad weather, the visual distance cannot be improved by changing the frequency; in highways, intersections, etc. In areas prone to accidents, the required frequency cannot be selected in a targeted manner to improve the pertinence of early warning. Contents of the invention [0003] Th...
