Description
technical field [0001] The invention relates to a portable solar lighting device. Background technique [0002] Large-area, high-brightness lighting devices are required for outdoor work sites in industries such as electric power, railways, and metallurgy, as well as work sites for emergency rescue and disaster relief and accident handling. In these conditions, convenient mains power supply is often not guaranteed, therefore, it is necessary to provide independent, portable lighting power supply. At the same time, since there are electrical equipment such as communication terminals, power devices, and testing instruments on the job site, it is often required that the mobile power supply can provide a suitable power supply interface for these equipment. Existing mobile power supply provides electric energy for the job site by the energy stored by itself, but when its energy is exhausted at the job site, it needs to replenish the electric energy in time, and it is also inconv...
