Solar light storage device

Abstract

The invention provides a solar light storage device which is capable of absorbing and storing light energy under the illumination of sun or light and other visible lights and used for night illumination or emergency illumination. The solar light storage device comprises a light concentrating device and a lamp cover. The solar light storage device is characterized by also comprising a cooling device consisting of a conduit, a pump, superconductive liquid in the pump and a heat dissipation box; the light concentrating device consists of a solar reflecting mirror, an optical screen, an optical fiber and a reflector; the lamp cover consists of inner and outer glass layers and light storage paint; and the light storage paint is prepared by the following steps: evenly mixing luminescent rare-earth material, strontium carbonate and aluminium oxide at high temperature, generating strontium aluminate luminescent rare-earth powder through solid reaction and then evenly mixing the strontium aluminate luminescent rare-earth powder, resin and addictives. By using the solar light storage device in the invention, the defects of the existing illuminator are solved, so that the solar light storage device has the characteristics of long persistence, high luminescent luminance, good light resistance, weather resistance and chemical stability, no precipitation, low construction, no radioactivity, no toxicity and harmless, safety and environmental protection and the like, the construction is simple, and the energy is saved.

Description

1. Technical field [0001] The invention relates to a solar light storage device, in particular to a solar light storage device capable of absorbing and storing light energy under sunlight or visible light irradiation such as lights, and used for night lighting or emergency lighting. 2. Background technology [0002] With the rapid development of my country's economy and the popularization of household appliances, power shortage has become a bottleneck restricting production and life. Last year, 24 provinces across the country had power cuts; in January this year, 21 provinces frequently ran out of power. It can be seen that the power shortage is not only an embarrassing thing during the peak period of summer electricity consumption. [0003] Moreover, at present, more than 60% of my country's electricity is thermal power generation, and the resulting carbon dioxide not only damages our health, but also leads to global warming; acid rain caused by sulfur dioxide has become a...

Problems solved by technology

[0004] Existing solar lighting lamps use solar panels to convert light energy to the battery for charging during the day. When night comes, the power of the battery is converted into alternating current by the high-frequency inverter to light up the lamp. After a set time, The lamp is automatically extinguished. Although it can achieve the purpose of converting sunlight into alternating current to light up the lamp, it is complex in efficiency and high in cost and efficiency.
