Rechargeable LED fabric-post emergency warning lamp
The invention discloses a rechargeable LED fabric-post emergency warning lamp and particularly relates to a traffic safety emergency warning lamp in the field of traffic and transportation. A transparent red waterproof PU fabric is adopted to manufacture a warning lamp 'post body', and stainless steel spiral circular rings and (antenna type) extension-type aluminum ribs serve as supports so that the warning lamp post body can be folded completely and can be small in size. The problem that an existing emergency warning lamp post body is formed through mold injection molding, is high in manufacturing cost, consumes electric energy and is poor in wind-resistant performance in use is solved. The problem that a battery cannot be charged, is poor in economical efficiency and is not environmentally friendly is solved by replacing a dry battery for power supply with a nickel-hydrogen rechargeable battery for power supply. By designing an LED spotlight at the top end of the warning lamp post body, the mode that a driver approaches and recognizes a warning signal is changed into the mode that the warning lamp flickers to send a light signal towards the sky to actively remind the driver in the rear and enable the driver to find a warning sign outside a safe vehicle distance, and the technical problem that accidents are easily caused by poor eyesight by the driver, too high vehicle speed and extreme weather is solved.
