Solar energy storage electro-optical device
One, technical field
The present invention relates to a kind of solar energy storage electro-optical device, especially a kind of can be in the sun or radiation of visible light such as light down absorption and store luminous energy, and the solar energy that is used for night illumination or emergency lighting stores up electro-optical device.
Two, background technology
Along with a large amount of of China's rapid economy development and household electrical appliance popularize, electricity shortage has become the bottleneck that restriction is produced, lived.Last year, there were 24 province power cuts to limit consumption in the whole nation; In January in this year, 21 province electricity consumptions signal for help repeatedly.This shows that short of electricity has been not only the awkward thing in peak of power consumption period in summer.
And the electric power of China is thermal power generation more than 60% at present, and consequent carbon dioxide has not only damaged our healthy, has also caused warming of global climate; The acid rain that sulfur dioxide causes has become agriculture stealthy killer.Water power is considered to clean energy resource usually, hardly realizes, barrage is built a dam and also can be flooded a large amount of farmlands, destroys forest, grassland, and bio-diversity is reduced, and ecological environment is produced influence difficult to the appraisal.In addition, certainly will produce more immigrant, cause very big burden to country.Therefore, using electricity wisely and make full use of natural daylight and be inevitable has been expected utilizing sunshine to this.
Existing solar energy illuminating light is by day, by solar panel transform light energy is charged a battery, when arriving night, the white high-frequency inverter of the electric energy of battery converts alternating current to lights lamp, through behind the setting-up time, lamp promptly extinguishes automatically, utilizes sunshine to be converted to the purpose that alternating current is lighted lamp though it can reach, so complicated than imitating, cost is higher than imitating.
Three, summary of the invention
The purpose of solar energy storage electro-optical device of the present invention is the deficiency that will solve above-mentioned lighting device, providing a kind of can and store visible absorption such as sunshine and light, the solar energy storage electro-optical device that is used for night illumination or emergency lighting, make its have persistence long, luminosity is high, light resistance, weatherability, chemical stability are good, do not precipitate, construct simply, cost is low, "dead", nontoxic, safety and environmental protection, characteristics such as energy-conservation.
The objective of the invention is to adopt following scheme to realize: a kind of solar energy storage electro-optical device, it comprises beam condensing unit and lampshade, be characterized in: it also comprises the cooling device of being made up of superconducting fluid in conduit, pump, the pump and heat radiation case, and described beam condensing unit is made up of solar energy reflection mirror, light sieve, optical fiber and reflector; Described lampshade is made up of inside and outside glassy layer and light-storing paint.
Above-mentioned solar energy reflection mirror is concavees lens, device is outdoor, sunshine on the solar energy reflection mirror reversal is mapped to light sieve at solar energy reflection mirror middle part, the sunshine that filters out infrared ray and heat through the light sieve by below the light sieve and the optical fiber that is connected with the light sieve be sent in indoor lampshade.
Said pump and heat radiation case apparatus and couple together pump and heat radiation case with the conduit that passes lampshade on indoor wall, make superconducting fluid in pump can the soil circulate heat radiation to lampshade and cool off.
Above-mentioned lampshade is a double-decker, internal layer surrounds circle by interior glassy layer, by the space that interior glassy layer encloses and outer glassy layer surrounds is vacuum layer, and the interior glassy layer of lampshade and outside coat light-storing paint equably on the glassy layer, make it to form a light-emitting lamp shade, transmitting the solar energy that enters in the lampshade by optical fiber makes lamp luminous, unnecessary sunshine then is stored on the interior light-storing paint of lampshade, on light-storing paint, can also transmit at luminous energy, be that the luminous energy that stores in vacuum layer and the internal layer can transmit mutually, and when this lamp electrified light emitting, lampshade also can be stored in a part of light in the lampshade, when the outage light fixture is not luminous, this lampshade will hold the luminous energy that stays at once and discharge, and can play the effect of night illumination or emergency lighting.
Above-mentioned light-storing paint is by luminescence rare earth material, strontium carbonate and alundum (Al, mixes at high temperature, generates the strontium aluminate rare earth luminescent powder through solid phase reaction, is mixed by strontium aluminate rare earth luminescent powder, resin and additive and forms.
The present invention adopts the beneficial effect of such scheme to be: 1) light-storing paint is to utilize the rare earth element extinction, hold a kind of special hair long optical coating that luminous principle is made behind the light, it holds light, luminous voluntarily after absorbing visible light radiation such as sunshine or light, beautiful in colour, fluorescent lifetime is long, fluorescent lifetime can reach 24 hours, ten minutes high brightness time; 2) chemical stability of light-storing paint good, do not precipitate, "dead", nontoxic, safety and environmental protection; 3) it is safer that cooling device makes the use of this device, and prolonged the service life of this device; 4) construction of solar energy storage electro-optical device is simple, cost is low; 5) this solar energy storage electro-optical device is of many uses, can not only the fitting-up building, the caution sign of public place, escape way, the LED that also can be used for man-made tourist site, culture, art and decorate is masked as special occasions, can also be as a hiding emergency lighting and low illumination.
