The photosensitizer layer is coated on a polymer polyimide flexible substrate, and two layers of polyolefin thermoplastic packaging A flexible polymer polyimide substrate and a photosensitizer layer are encapsulated between the films.

Preferably, the control box is installed at the bottom of the lamp body, and a storage battery and a controller are arranged in the control box.

Preferably, an infrared human body sensor is also provided on the outer periphery of the polycarbonate transparent lampshade. When the photoreceptor senses that the light is dark and the thin-film solar battery is no longer charging, it is judged as evening or night. When the infrared human body sensor senses that someone is approaching (when the distance between the person and the infrared human body sensor is ≤8m), the light will be turned on automatically.

Preferably, the light pole is spliced by four sections, the first section is fixed on the bottom of the lamp body, and the main switch is provided on the first section, the second section, the third section, and the fourth section are detachable and installed, and adjacent There is a splicing joint between the two sections, the second and third sections are cylindrical, and the end of the fourth section is sharply conical to facilitate smooth insertion into the soil.

A solar automatic induction lawn lamp of the utility model has the characteristics of safety, energy saving, convenience and environmental protection, and its beneficial effects are as follows:

1) Solar automatic lawn lamp is an independent power generation system, which can independently convert solar energy into electrical energy, and convert electrical energy into heat energy for lighting and decoration without the need for wire transmission.

2) After the solar automatic sensing lawn light turns on the main switch, it converts sunlight energy into electrical energy during the day, and the thin-film solar cell charges the battery. The photoreceptor embedded in the top of the polycarbonate transparent lampshade automatically turns on the light at dusk. The automatic sensor lawn light is suitable for lawns in courtyards, municipal constructions, parks, villas and residential areas. It can be inserted into the lawn and automatically controlled to turn on the lights.

3) In the daytime of cloudy and rainy days, the battery charging capacity of thin-film solar cells is not enough to provide LED lights for a whole night. In order to save the battery power, the utility model adds an infrared human body sensor on the outer periphery of the polycarbonate transparent lampshade, which can effectively Energy saving. When the photoreceptor senses that the light is dark and the thin-film solar battery is no longer charging, it is judged as evening or night. When the infrared human body sensor senses that someone is approaching (when the distance between the person and the infrared human body sensor is ≤8m), the light will be turned on automatically.
