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 the side of exciting thereof
Method.
Background technology
Long-afterglow material is a kind of light accumulation type embedded photoluminescent material, after it is excited by the light of certain time and some strength, after exciting stopping
A kind of material of meeting continuous illumination, its continuous illumination intensity is referred to as twilight sunset by the process of height gradually step-down.Its luminosity curve is that negative exponential function is with double
The superposition of curvilinear function, after stopping exciting, the time, the shortest brightness was the highest, and the time, the longest brightness was the lowest.
Solar energy refer to utilize sunlight generate electricity (or heating) energy is provided, wherein the most wide variety of solar electrical energy generation utilizes exactly at present
Photoelectric conversion mode, solar electrical energy generation is a kind of emerging renewable eco-friendly power source.
Long afterglow product has been widely applied to the numerous areas such as indoor fire-fighting exit signs mark, boats and ships mark at present.Especially interior length twilight sunset disappears
Anti-exit signs 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 refers to
Showing that product is generally used in indoor, after it is excited by indoor environment light, play low light level inducing action under night or powering-off state, guide is built
Build the evacuating personnel escape in thing.Typically there is illumination in the place having night personnel to go to, and when in emergency circumstances power-off suddenly, the evacuation of personnel is main
Concentrate in 30 minutes (the most also less than 60 minutes)；Simultaneously because indoor relative closure, the intensity of veiling glare is the lowest.Therefore,
Majority state long-persistence luminous fire-fighting mark product light levels be 10 minutes between 100～300mcd/sqm, the luminosity of 1 hour
Between 14～40mcd/sqm.
Some research institutions and company are also attempting long afterglow products application to outdoor both at home and abroad, such as Chinese patent 201120106933.0 disclosure
A kind of long afterglow luminescence reflection combined traffic safety mark, this product is just applied on outdoor highway.(using of the most visible open report
D65 standard light source, excites 10 minutes 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 25
About mcd/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, at this
During individual, long afterglow is in the process consuming the energy supplementary to it more than ambient light of the energy of luminescence.If long afterglow product the most out of doors
Only excite by ambient light, after waiting until, the when that people needing long-persistence luminous product to provide guide complete night in the evening, the brightness of this product
Decay about 2 hours.Owing to not having strong excitation source, simultaneously because the veiling glare of open air is the most, environment is not the darkest, because of
These people often feel that long-persistence luminous product illumination effect out of doors is undesirable.Improve long afterglow product and use the luminescence under environmental condition out of doors
Brightness is the main bugbear always perplexing the popularization and application out of doors of this product.
Certainly, there have been some solar LED light-emitting devices selling, such as solar energy floor-lamp, solar energy park ornament lamp,
Solar energy spike etc..These products are all to utilize solar panel, accumulator, control circuit, LED illuminator and related accessory etc., according to reality
Border needs to be designed to different patterns and shape, thus is manufactured into the solar LED light-emitting device of needs.The area of solar cell is at present
110W/m2, the solar-electricity power output plate of 10 centimetres * 10 centimetres only has 1.1 watts, additionally, due to the impact being easily subject to weather (weather)
With the restriction in geographical position, 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, is typically all and uses bigger solar panel as far as possible, but excessive solar panel, cause product cost too high；Additionally
Some light-emitting device is limited by 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, by day
Solaode and long-afterglow material are charged and excite simultaneously by sunlight, drive electroluminescent device luminescence also at night by solaode timing
Long-afterglow material is supplemented and excites, make long-afterglow material tend to high-order luminance the most all the time, owing to solar energy system is the logical of discontinuity
The electroluminescent device supplementing to long afterglow product of overdriving excites, and greatly reduces the requirement of the accessory such as area and battery capacity of solar energy system.
The invention changes and only relies on the present situation that environment light source excites under conventional long afterglow product use state out of doors, introduces solaode also
Electroluminescent device is driven so that it is inspired long-lasting material while luminescence own, such long afterglow is sent out by IC (circuit controller) intermittent
Luminescent material can be excited by intermittent, thus the luminosity ratio that long-afterglow material is in actual working environment is thought and only excited by ambient light
The raising of the order of magnitude.
Daytime, sunlight supplemented energy to long-afterglow material and solar cell system simultaneously.First it is that long after glow luminous material sends when night comes
Visible ray, when the luminosity of light-sensitive element perception ambient light (can also allow the luminescence of light-sensitive element perception long-afterglow material less than after a certain desired value
Brightness is less than after a certain desired value), controller controls solar cell system work, lights the electroluminescent device in long-lasting phosphor；Electroluminescent
While luminescent device luminescence, long after glow luminous material is excited supplementary energy.When electroluminescent device quits work when, long after glow luminous material
Luminescence, 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 be according to different long-afterglow materials, specialized designs controller circuitry；Electroluminescent device can also be regulated by the size controlling driving battery
Brightness.Next by regulation dutycycle (in Fig. 2: the working time t1 of electroluminescent device and the ratio of dwell time t2 of electroluminescent device)
Control work and the time ratio of stopping of electroluminescent device, reach the optimal balance point of economize on electricity and illumination effect, be allowed to play optimal performance.
