A high-power light emitting device road sign bearing capacity

A high-power light emitting device road sign bearing capacity, according to the present application by the intermediate flap is connected to the plate by the force of the spring, and connected to the side plate is fixed to the road surface, the pressure plate is connected to the link and the buffer spring, is fixed to one end of the buffer spring transducer housing, and the other end is fixed to the pressure plate, the piezoelectric stack is fixed to the transducer housing; transducer housing defines an internal chute; the piezoelectric stack by a plurality of piezoelectric ceramic sheets consisting of an epoxy glue bonding . This means the pressure can be a variety of vehicle traveling on a road that is converted to shock and vibration generated by the piezoelectric stack, and thus to achieve electromechanical energy conversion device, various light emitting device identification may be provided to provide power to the road, because the road various vehicle traveling pressure produced is then converted to the shock vibration of the piezoelectric stack by a rack and pinion, therefore, in the case where the device withstand high loads will not cause damage of the piezoelectric stack, to solve the corresponding problem.
