Description

Technical Field

[0001] This utility model relates to the field of road traffic technology, and in particular to a photovoltaic light-emitting flat panel. Background Technology

[0002] The safety hazards of pedestrians crossing crosswalks at night are significant, mainly due to the generally insufficient lighting at and around the crosswalks (such as sparse, low-brightness, or no streetlights), resulting in dim lighting that severely impairs drivers' visibility. Night driving is already challenging due to poor light and driver fatigue. In poor lighting, pedestrians easily blend into the darkness and are difficult for drivers to spot in advance, often only becoming noticeable when they are close or completely unnoticed. This lack of visibility greatly reduces the driver's reaction time and braking distance, making it difficult to avoid or brake in time, seriously threatening pedestrian safety. Utility Model Content

The controller controls the LED lights to illuminate based on pressure changes from the pressure sensor, indicating that a pedestrian is crossing the crossing and thus promptly alerting drivers of vehicles at night.

The tempered glass 1, photovoltaic module 2, pressure sensor 4, power supply unit 5, and controller are all mounted on the substrate 3. The tempered glass 1 and photovoltaic module 2 are stacked sequentially from top to bottom. The tempered glass 1 is used to protect the photovoltaic module 2, and the photovoltaic module 2 is used to generate electricity using solar energy.

The pressure sensor 4 is connected to the controller and is used to transmit pressure signals to the controller. An LED light is provided on the tempered glass 1, and the LED light is connected to the controller. In use, when a pedestrian steps on the photovoltaic light-emitting flat panel, the pressure sensor 4 senses the pressure change and transmits the pressure signal to the controller. The controller controls the LED light to light up, indicating that a pedestrian is crossing the crosswalk at this time, thereby reminding drivers of vehicles at night to pay attention to pedestrians crossing the crosswalk in time and take evasive action in advance to avoid traffic accidents.

The transparent protective layer 21 and the moisture-proof board 25 are encapsulated on both sides of the photovoltaic panel 24. The transparent protective layer 21 is used to protect the photovoltaic panel 24 from external environmental corrosion. The transparent protective layer 21 also allows sunlight to pass through and irradiate the photovoltaic panel 24. The photovoltaic panel 24 is used to absorb sunlight to generate electricity and store it in the power supply unit 5. The moisture-proof board 25 is used to prevent moisture contained in the substrate 3 from being released from the substrate 3 after being heated and invading the photovoltaic panel 24, causing short circuit damage to the photovoltaic panel 24.

[0028] Preferably, the photovoltaic module 2 further includes a first sealant layer 22 and a second sealant layer 23. The first sealant layer 22 is disposed between the transparent protective layer 21 and the photovoltaic panel 24, and the second sealant layer 23 is disposed between the photovoltaic panel 24 and the moisture-proof board 25. The first sealant layer 22 and the second sealant layer 23 are used to encapsulate the photovoltaic panel 24 to prevent dust, moisture and other substances in the external environment from entering the photovoltaic panel 24 and avoid damaging the photovoltaic panel 24.

[0029] Preferably, the pressure sensor 4 is a pressure sensor in the prior art; the minimum pressure detection threshold of the pressure sensor 4 is 0.1 MPa.
