Abstract
The utility model relates to an LED (light emitting diode) pedestrian crosswalk realizing electricity generation by using pressure. The LED pedestrian crosswalk consists of a pressure electricity generation device, a bridge type rectifier, a voltage stabilizer, a sensor, a controller, a storage battery, an LED luminous plate, a piezoelectric material layer, a reset spring and a toughened glass plate. When a motor vehicle or a pedestrian goes on the pavement, the pressure effect is generated on the piezoelectric material, the piezoelectric material is pressured to bend for discharging certain electric energy, the electricity energy is introduced into the bridge type rectifier, alternating current is converted into direct current electricity through the bridge type rectifier, and the direct current electricity is stored into the storage battery after being subjected to the voltage stabilization through the voltage stabilizer. The pressure of the motor vehicle or the pedestrian on the piezoelectric material layer is utilized for generating electric energy, so the pedestrian crosswalk realizes the lamination illumination under the conditions with insufficient light rays in cloudy days, rainy days or nighttime and the like, motor vehicle drivers are promoted to slow down the speed, the road safety of the public traffic road is improved, and the characteristics of energy saving and environment protection are realized.
Description
Technical field
The utility model relates to a kind of cross walk, relates in particular to a kind of LED cross walk that utilizes pressure electricity-generating.
Background technology
Now, in the situation that urban traffic is blocked up day by day, people's safety more and more can not get effective guarantee.Because in the highway section that the needs such as cross walk slow down, automobile driver is not in time taked the deceleration measure often, especially in the situation of the insufficient lights such as cloudy day or night, automobile driver is difficult to see clearly cross walk, thereby continue to run at high speed, caused huge hidden danger to traffic safety like this.
Summary of the invention
For addressing the above problem, the utility model provides a kind of LED cross walk that utilizes pressure electricity-generating, is comprised of pressure generating set, bridge rectifier, stabilizator, sensor, controller, battery, LED luminous plaque, armorplate glass, it is characterized in that:
1, pressure generating set is comprised of piezoelectric material layer, back-moving spring and armorplate glass, piezoelectric material layer one end is drawn wire and is connected bridge rectifier, the output of bridge rectifier connects stabilizator, the output of stabilizator connects battery, the output connecting sensor of battery, the output of sensor connects controller, and the output of controller connects stabilizator, and another output of battery connects the LED luminous plaque.
2, described piezoelectric material layer is uniform is embedded on the road.
The beneficial effects of the utility model are:
1, the present invention utilizes motor vehicle or pedestrian that the pressure-acting of piezoelectric material layer is produced electric energy, make cross walk luminous lighting in the situation of the insufficient lights such as cloudy, rainy or night, the Reduced Speed Now of prompting automobile driver improves the public transport road safety, has the characteristics of energy-conserving and environment-protective.

The specific embodiment
As shown in Figure 1, the present invention is comprised of pressure generating set 1, bridge rectifier 2, stabilizator 3, sensor 4, controller 5, battery 6, LED luminous plaque 7, piezoelectric material layer 8, back-moving spring 9, armorplate glass 10.Wherein, pressure generating set 1 is comprised of piezoelectric material layer 8, back-moving spring 9 and armorplate glass 10, piezoelectric material layer 8 one ends are drawn wire and are connected bridge rectifier 2, the output of bridge rectifier 2 connects stabilizator 3, and the output of stabilizator 3 connects the output connecting sensor 4 of battery 6, battery 6, the output of sensor 4 connects another output connection LED luminous plaque 7 of the output connection stabilizator 3 of controller 5, controller 5, battery 6.After piezoelectric material layer 8 is subject to certain pressure, back-moving spring 9 is compressive state, when the pressure of piezoelectric material layer 8 disappears, and the power that back-moving spring 9 elongations make progress to piezoelectric material layer 8, make the state before piezoelectric material layer 8 returns to pressurized at once, play the effect of the damping that resets.
Operating principle of the present invention is: when motor vehicles or pedestrian advance on the road surface, piezoelectric is produced pressure-acting, the piezoelectric bend by pressure is emitted certain electric energy, be incorporated in the bridge rectifier through wire, bridge rectifier changes alternating current into direct current and is stored in the battery after the stabilizator voltage stabilizing, by sensor be used for obtaining extraneous light information, when intensity of illumination is higher than on the preset value in limited time the lighting-off of LED luminous plaque; Prescribe a time limit when intensity of illumination is lower than under the preset value, the LED luminous plaque provides illumination.Make cross walk luminous lighting in the situation of the insufficient lights such as cloudy, rainy or night, the Reduced Speed Now of prompting automobile driver improves the public transport road safety.
