Description

Technical Field

[0001] The embodiment of the utility model belongs to the field of lighting technology, and specifically relates to an LED solar lamp. Background Art

[0002] With traditional energy sources becoming increasingly scarce, solar energy is being used more and more widely. In particular, solar power generation has become a mature and promising industry in just a few years. Furthermore, with the development and advancement of solar photovoltaic technology, and the dual advantages of solar lighting products in terms of environmental protection and energy conservation, the application of solar lamps has gradually become widespread.

[0003] Currently, solar lanterns rely on photovoltaic panels to generate electricity, which is then stored in batteries as part of their energy supply. In my country, the optimal orientation for photovoltaic panels is generally due south, and solar radiation peaks just after noon. This occurs between 12:00 and 1:00 PM, when the sun is perpendicular to the panels at a 90-degree angle. This is when photovoltaic power generation peaks. If the panels are tilted east or west by 30 degrees from due south, their power generation decreases by 10% to 20%. This performance also varies significantly across different latitudes and longitudes, and across different seasons. Therefore, a solar lantern with adjustable photovoltaic panel angles is urgently needed to achieve higher power generation efficiency. Utility Model Content
