Abstract

The invention discloses an off-grid lighting system, which comprises a solar energy temperature difference generating device, a storage battery (5) and load (6), wherein the solar energy temperature difference generating device is connected with the load (6), the storage battery (5) is connected between the solar energy temperature difference generating device and the load (6), and the solar energy temperature difference generating device comprises a solar energy thermal collector (1) and a temperature difference generating module (2). The solar energy thermal collector (1) is connected with the temperature difference generating module (2) through a warming device (3), and the warming device (3) is connected with the solar energy thermal collector (1) and the temperature difference generating module (2) through guide pipes. The off-grid lighting system is simple in structure, low in utilizing cost, high in generating efficiency and reliable and stable in performance, and is an ideal, low-price, safe lighting product which uses non-fossil fuel.

Description

technical field [0001] The invention relates to a lighting system, in particular to a thermoelectric off-grid lighting system using solar energy as power generation power. Background technique [0002] Off-grid lighting systems refer to systems that are not connected to commercial power grids and use independent power generation devices to provide lighting applications, including the use of wind power, marine and solar photovoltaic power generation systems. In areas where electricity cannot be provided and the cost of grid laying is high, off-grid lighting systems can be used directly for lighting. [0003] Most areas in the world have already used power resources normally, but there are still some areas where the use of power is still not optimistic. [0004] Especially the problem of electricity usage in Africa. The World Bank pointed out that Africa has a population of 1 billion (2009), accounting for about 15% of the world's total population. Areas that are not yet con...
