Abstract

A solar-powered portable energy-saving light-emitting traffic sign has a main body, with its traffic sign surface provided with LED luminous bodies. A solar energy device is assembled onto the support bar of the main body, and has a photovoltaic panel and rack. A battery is assembled onto the support bar. A starting switch enables activation and manual highlighting of LED bodies on the traffic sign. A timer is assembled onto the support bar to set and control auto-off time of the LED bodies. A wireless transmitter for synchronous transmission control, is assembled onto the support, and composed of a wireless transmitting module and a wireless receiving module. The wireless transmitting module is activated by the starting switch to transmit a wireless starting signal. The receiving module is normally opened. When the wireless receiving module receives the starting signal, the LED bodies can also be highlighted.

Claims

1. A solar-powered portable energy-saving light-emitting traffic sign, comprising:

at least a main body having a support bar and at least a traffic sign surface positioned on the support;

the traffic sign surface is provided with LED luminous bodies generating light-emitting effects;

a solar energy device, assembled onto the support bar of the main body, and composed of a photovoltaic panel and a rack;

of which the rack is used to mount the photovoltaic panel onto the support;

a battery, assembled onto the support bar of the main body and electrically connected with the photovoltaic panel, so as to store the electric energy generated by the photovoltaic panel;

a starting switch, assembled onto the support bar of the main body, enabling the users to activate and highlight manually LED luminous bodies on the traffic sign surface;

a timer, assembled onto the support bar of the main body, and used to set and control auto-off time of the LED luminous bodies;

a wireless transmitter for synchronous transmission control, assembled onto the support bar of the main body, and composed of a wireless transmitting module and a wireless receiving module;

of which the wireless transmitting module is activated by the starting switch to transmit a wireless starting signal;

of which, the receiving module is normally opened;

when the wireless receiving module receives the wireless starting signal, the LED luminous bodies on the traffic sign surface can also be highlighted;

hence, the traffic sign powered by the solar energy allows to start it manually, switch off regularly, or activate and control multiple sets simultaneously to reduce the configuration cost and realize better energy conservation effect in the traffic environment of low utilization rate.

2. The structure defined in claim 1, wherein if a plurality of main bodies is configured and the starting switch on either of the main bodies is started, the wireless transmitting module is activated to transmit a wireless starting signal, and the wireless receiving module on the remaining main bodies receives said wireless starting signal to highlight the LED luminous bodies on the traffic sign surface of the main body, thereby realizing synchronous wireless startup of multiple traffic signs.

4. The structure defined in claim 1, wherein the battery and timer can be combined and assembled into an electromechanical box, which is then mounted onto the support bar of the main body.

5. The structure defined in claim 1, wherein said wireless transmitter is mounted at either side of the photovoltaic panel.

3. The structure defined in claim, wherein the traffic sign surface of the main body is provided with either graphic symbols or lamp signal.
