Abstract

The present disclosure provides a lighting method, system, and streetlamp. The present disclosure may enable the streetlamp to illuminate according to the location of the vehicles, so as to avoid the wasting of electrical energy due to activation of the streetlamp during no passing of vehicles for a long time, by transmitting travelling information for indicating longitude and latitude of an adjacent vehicle by the vehicle, and providing illuminating for the roads upon determining that the vehicle is in the illumination coverage of the streetlamp by the processor in the streetlamp.

First claim

What is claimed is:

1. A streetlamp comprising: a communication module, a processor, a memory, a locating module, an illumination sensor and a sleeping power supply circuit and a lighting module, the communication module, the memory, the locating module, the illumination sensor, the sleeping power supply circuit and the lighting module being electrically connected with the processor respectively,
wherein the communication module is configured to receive travelling information for indicating longitude and latitude of a vehicle,
the memory is configured to store illumination coverage of the streetlamp,
the locating module is configured to acquire longitude and latitude data of a location where the streetlamp is located,
the illumination sensor is configured to measure an illumination of a current road,
the sleeping power supply circuit is configured to supply power to the locating module and the communication module according to a sleeping mode and a normal working mode,
the processor is configured to
trigger an activation of the lighting module, when the longitude and latitude of the vehicle received by the communication module are in the illumination coverage stored by the memory, and otherwise, turn off the lighting module,
calculate the illumination coverage based on the longitude and latitude data of the location where the streetlamp is located and an illumination radius of the streetlamp, and
trigger the sleeping power supply circuit to supply power in the sleeping mode when the illumination measured by the illumination sensor is lower than a preset threshold, and otherwise trigger the sleeping power supply circuit to supply power in the normal working mode,

the lighting module is configured to provide illumination for roads.

2. The streetlamp according to claim 1 , wherein the locating module comprises a GPS chip.

3. The streetlamp according to claim 1 , wherein the lighting module comprises a light source, a power supply and a relay, the light resource and the power supply are electrically connected with the relay, and
the relay is configured to maintain the electrical connection for the power supply and the light source when the processor triggers the activation of the lighting module, and disconnect the electrical connection for the light source and the power supply when the processor triggers the lighting module to be turned off.

4. The streetlamp according to claim 1 , wherein the communication module comprises a V2X (Vehicle to X) communication chip.

5. A lighting system comprising the streetlamp according to claim 1 and a vehicle, and
the vehicle is configured to transmit travelling information for indicating longitude and latitude of the vehicle to the streetlamp.

6. A lighting method comprising:
supplying power to a locating module and a communication module in a sleeping mode when illumination of a current road is lower than a preset threshold, and otherwise supplying power to the locating module and the communication module in a normal working mode,
receiving travelling information for indicating longitude and latitude of a vehicle,
acquiring longitude and latitude data of a location where the streetlamp is located,
calculating an illumination coverage based on the longitude and latitude data of the location where the streetlamp is located and an illumination radius of the streetlamp,
turning on the streetlamp when the longitude and latitude of the vehicle are in the illumination coverage of the streetlamp, and otherwise,
turning off the streetlamp.

7. The lighting method according to claim 6 , wherein the travelling information further comprises speed or heading direction.

8. The lighting method according to claim 6 , wherein the travelling information further comprises speed and heading direction.
