Description
Technical field
The invention relates to a kind of long-persistence luminous system with solar energy, is specifically related to a kind of long-persistence luminous system of solar energy and exciting method thereof.
Background technology
Long-afterglow material is a kind of light accumulation type embedded photoluminescent material, when it is subject to after the light of certain time and some strength excites, after exciting stopping can a kind of material of continuous illumination, its continuous illumination intensity is referred to as twilight sunset by the process of height step-down gradually.Its luminosity curve is negative exponential function and the superposing of hyperbolic function, and after stopping exciting, the time, more short brightness was more high, and the time, more long brightness was more low.
Solar energy refer to utilize sunlight generate electricity (or heating) energy is provided, wherein wide variety of solar electrical energy generation utilizes photoelectric conversion mode exactly at present, and solar electrical energy generation is a kind of emerging renewable eco-friendly power source.
Current long afterglow product has been widely applied to the numerous areas such as indoor fire-fighting exit signs mark, boats and ships mark.Especially interior length twilight sunset fire-fighting evacuation instruction product is its main uses, and many countries have promulgated the relevant criterion that long-persistence luminous exit signs identifies.Long afterglow fire-fighting evacuation instruction product is generally used in indoor, after it is subject to the exciting of indoor environment light, plays low light level inducing action under night or powering-off state, guides the evacuating personnel escape in building.Having night the place that personnel go to generally to have illumination, when in emergency circumstances power-off suddenly, the evacuation of personnel is concentrated mainly in 30 minutes (generally also less than 60 minutes)；Simultaneously because indoor relative closure, the intensity of veiling glare is non-normally low.Therefore, the light levels of the long-persistence luminous fire-fighting of majority state mark product be 10 minutes between 100～300mcd/sqm, the luminosity of 1 hour is between 14～40mcd/sqm.
Some research institutions and company are also attempting long afterglow products application to outdoor both at home and abroad, for instance Chinese patent 201120106933.0 discloses a kind of long afterglow luminescence reflection combined traffic safety mark, and this product is just applied on outdoor highway.(the use D65 standard light source of visible open report at present, 10 minutes are excited under the light intensity of 1000LX) the maximum brightness level of long-lasting phosphor is at 30 minutes 550mcd/sqm, brightness about the 250mcd/sqm of 1 hour, brightness about the 130mcd/sqm of 2 hours, 3 hours about 80mcd/sqm, 6 hours about 25mcd/sqm.Due to out of doors, setting that sky grows dark completely from the sun is a progressive process, it usually needs about 2 hours, and long afterglow is in the consuming more than the environment light process to energy that it supplements of the energy of luminescence in this process.If therefore long afterglow product only excites by environment light out of doors, after waiting until, time people need long-persistence luminous product to provide guide, the brightness of this product has decayed about 2 hours complete night in the evening.Owing to not having strong excitation source, simultaneously because the veiling glare of open air is relatively many, environment is not as dark, and therefore people often feel that long-persistence luminous product illumination effect out of doors is undesirable.Improving long afterglow product uses the luminosity under environmental condition to be the main bugbear always perplexing the popularization and application out of doors of this product out of doors.
Certainly, some solar LED light-emitting devices have been had to sell at present on the market, for instance solar energy floor-lamp, solar energy park ornament lamp, solar energy spike etc..These products are all utilize solar panel, accumulator, control circuit, LED illuminator and related accessory etc., are designed to different patterns and shape according to actual needs, thus manufacturing the solar LED light-emitting device of needs.The area of current solar cell is 110W/m2, the solar-electricity power output plate of one 10 centimetres * 10 centimetres only has 1.1 watts, additionally, due to the restriction of the impact and geographical position that are easily subject to weather (weather), general solar-powered illuminator is general it is difficult to ensure that light device lasts through the night sends stronger light.In order to solve this problem, it is typically all and adopts bigger solar panel as much as possible, but excessive solar panel, cause that product cost is too high；Additionally some light-emitting device is subject to the restriction of installation site and condition, should not install excessive solar panel.
Summary of the invention
The invention to solve the technical problem that and to be to provide a kind of long-persistence luminous system of solar energy and exciting method thereof.
The thinking of the invention:
For the problems referred to above, the invention proposes a kind of long-persistence luminous system of solar energy.With long-afterglow material for main body luminescent device, solaode and long-afterglow material are charged and excite simultaneously by sunlight by day, and excite long-afterglow material is supplementary by solaode timing driving electroluminescent device luminescence at night, long-afterglow material is made to tend to high-order luminance in the dark all the time, due to solar energy system be discontinuity by driving electroluminescent device supplementing to long afterglow product to excite, greatly reduce the requirement of the accessory such as area and battery capacity of solar energy system.
The invention changes and only relies on, under conventional long afterglow product use state out of doors, the present situation that environment light source excites, introduce solaode and drive electroluminescent device by IC (circuit controller) intermittent, make its inspired long-lasting material while is luminous itself, such long after glow luminous material can be subject to exciting of intermittent, thus the luminosity that long-afterglow material is in actual working environment is than thinking the raising only having excited the order of magnitude by environment light.
Daytime, sunlight supplemented energy to long-afterglow material and solar cell system simultaneously.First it is that long after glow luminous material sends visible ray when night comes, when after the luminosity of light-sensitive element perception environment light is lower than a certain desired value (after the luminosity of light-sensitive element perception long-afterglow material can also be allowed lower than a certain desired value), controller controls solar cell system work, lights the electroluminescent device in long-lasting phosphor；While electroluminescent device is luminous, long after glow luminous material is excited supplementary energy.When electroluminescent device is out-of-work time, long after glow luminous material is luminous, so that the product of the invention maintains on certain luminosity (see Fig. 1: the product of the invention maintains principle of luminosity figure).Can according to different long-afterglow materials, specialized designs controller circuitry；Can also by controlling the brightness driving the size of battery to regulate electroluminescent device.The work of electroluminescent device and the time ratio of stopping is controlled by regulating dutycycle (in Fig. 2: the ratio of the working time t1 of electroluminescent device and the dwell time t2 of electroluminescent device), reach the optimal balance point of economize on electricity and illumination effect, so as to play optimal performance.
