  • Publication number: 20070011928
    Abstract: A triangular warning sign for vehicles includes a triangular carrier board, a power supply and a mount. The triangular board is used for carrying a triangular warning sign and the power supply while the mount makes the triangular board stand perpendicular to the ground. The triangular warning sign is composed by electro luminescent pieces or a plurality of light-emitting diodes. The power supply can be solar power supply, batteries, or a car charger and it can automatically switch between the solar energy and batteries depending on occasions for providing the triangular warning sign power. In usage, the invention illuminates by Electro Luminescent or light-emitting diode to achieve features of electricity-saving, safety, and enough brightness for better warning effect, more convenience and energy-saving. The present invention can further disposed with an alarm and the power supply is with both AC and DC charging capabilities.
