Novel solar illuminating device

Abstract

The invention relates to a novel solar illuminating device which comprises a lampshade, a solar cell and a plurality of luminous bodies. The novel solar illuminating device is characterized in that at least one luminous body is directly connected with an alternating-current mains supply, the rest luminous bodies are electrically connected with the solar cell by leads, the lampshade is positioned above the luminous bodies, and the solar cell is adhered on the inner wall of the lampshade. The remarkable advantage that the CIGS (copper indium gallium selenide) thin-film solar cell is utilized, the flexible CIGS thin-film solar cell is adhered on the inner wall of the lampshade, light emitted by a fluorescent lamp is absorbed to generate stable current to be supplied for remaining light sources, energy storage devices are omitted, the structure of an existing solar lamp is simplified, the novel solar illuminating device can also be used in an indoor environment, environmental limitation that the existing solar lamp needs to be placed in an outdoor environment to be charged is broken, and conventional energy is saved.

Description

technical field [0001] The invention relates to a novel solar lighting device. Background technique [0002] With global warming and the reduction of traditional carbon-containing energy reserves around the world, new energy sources are more and more widely used, and more and more attention has been paid to them. As a green and environmentally friendly energy source, solar energy has been widely used in people's daily life. Various solar lamps are also used in various occasions and environments. Most of the solar panels of existing solar lamps are polycrystalline silicon or monocrystalline silicon solar panels, which are relatively hard, shattered, inflexible, and have harsh requirements on lighting conditions, which makes people focus on thin-film solar cells. Flexible CIGS thin-film Solar cells are light and thin, easy to bend, easy to install, good in low light, and have good photovoltaic output characteristics at high temperatures, and have greater actual power output t...

Problems solved by technology

Most of the solar panels of existing solar lamps are polycrystalline silicon or monocrystalline silicon solar panels, which are relatively hard, shattered, inflexible, and have harsh requirements on lighting conditions, which makes people focus on thin-film solar cells. Flexible CIGS thin-film Solar cells are thin, easy to bend, easy to install, good in low light, and have good photovoltaic output characteristics at high temperatures, and have greater actual power output than crystalline silicon solar cells

At present, solar lights on the market are equipped with energy storage devices, which generally have disadvantages such as complex structure, inconvenient use, and uneven illumination.
