Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment 1
As shown in Figure 1, the invention provides light emitting directory board used on road, comprising: power module and light emitting module, power module comprises transformer 101, rectifier 102, for providing constant-current supply to light emitting module.
As shown in Figure 3, light emitting module 107 comprises substrate 1071, luminescent layer 1072 and the accumulation of energy layer 1073 being superimposed together successively, be used for showing customizing messages, wherein luminescent layer 1072 forms word or pattern by electroluminescent material, and luminescent layer 1072 is fixedly connected with substrate 1071, for example, in order to simplify technique, above-mentioned luminescent layer 1072 can also be one-body molded with substrate 1071, accumulation of energy layer 1073 is fixedly connected with luminescent layer 1072, accumulation of energy layer material therefor should be transparent, such as using acrylic acid type energy stroage and liminous water paint to form in the middle of being uniformly distributed in resin or plastics, and its profile should be consistent with luminescent layer 1072, need to form word or the pattern consistent with luminescent layer 1072, like this when luminescent layer 1072 is luminous, light can see through the outside scattering of accumulation of energy layer 1073, indication pedestrian or vehicle, and accumulation of energy layer 1073 can absorb luminescent layer 1072 illumination energy, when luminescent layer is non-luminous, contained energy-saving luminous material in accumulation of energy layer, such as acrylic acid type energy stroage and liminous water paint, zinc sulphide is luminescent material, rare earth-activated luminous alkali earth metal aluminate luminescent material etc., can discharge the luminous energy absorbing and send visible ray, substitute luminescent layer luminous, show customizing messages, indication pedestrian or vehicle.
Energy-accumulating luminous mechanism for energy-saving luminous material is simply described as follows, and energy-saving luminous material belongs to solid luminescent material, and solid luminescent material is a kind ofly the energy exciting can be transformed into the solid matter of visible ray.When light beam incides such luminescent material, between those dissimilar subgrades, there is the electronics of the crossing of the energy level phenomenon, will between the ground state of ion and excited state, transition campaign occur, now the energy of light beam will be transferred to the electronics being excited, and the light of this wavelength has been absorbed.But the electronics in excited state is a kind of metastable state, once illumination stops, the energy that this electronics will discharge this wavelength light jumps and gets back to ground state, thereby causes this material luminescence, is a kind of energy-accumulating luminous process.Therefore accumulation of energy layer 1073 is under predetermined condition, and luminescent layer 1072 stops under luminous condition, will send visible ray and show customizing messages.Like this in the normal situation of power supply, for example, connect outside 220V alternating current, by transformation and rectification circuit, to light emitting module 107, provide power supply, make light emitting module active illuminating, to show specific indication or warning message, and in the situation that AC-powered is interrupted, accumulation of energy layer also can maintain the luminous of a period of time.
Another example, in order to guarantee that the power failure in the situation that, direction board can normally be worked, and an emergency service module can also be set in circuit, comprises accumulator 104 and sun power electroplax 103, utilizes sun power, sun power electroplax 103 is to charge in batteries.
Another example, in order to improve light emitting module waterproof, protection against the tide, antifreeze, anti-ly to tan by the sun ability, can also be in light emitting module 107 outer setting one transparent face mask (not shown)s.
Embodiment 2
On the basis of above-mentioned each example; in order to improve the safety and stability of circuit working; as shown in Figure 2; one additives for overcharge protection device 106 is set between rectifier 102 and accumulator 104; for stopping when accumulator 104 voltages reach mxm. its charging, meanwhile, can also be between accumulator 104 and light emitting module 107; one overdischarge protector 105 is set, for stop accumulator when battery tension reaches minimum, externally discharges.Like this, can protect accumulator, extend its serviceable life.
Embodiment 3
As shown in Figure 4, on the basis of above-mentioned arbitrary embodiment, luminescent layer 1072 uses light emitting diode (LED) or Organic Light Emitting Diode (OLED) to form, such as can be on the outline line of word or pattern intensive LED or the OLED of arranging, light like this after LED or OLED, just form luminous profile word or contour patterns, circle shown in figure is that LED is arranged on and on outline line, forms profile word and " stop "; LED or the intensive inner (not shown) of each outline strokes that is arranged on word shown in Fig. 4 of OLED can certainly be lighted after LED or OLED like this, just formed word or the pattern of Integral luminous.
Embodiment 4
On the basis of above-mentioned arbitrary embodiment, can be by changing the connected mode of accumulation of energy layer 1073 and luminescent layer 1072, reach better illumination effect, such as, can use accumulation of energy pigment to be coated on LED surface, on LED surface, form one deck light-emitting film, after LED lights like this, accumulation of energy layer just can absorb illumination energy, after LED power down, such as running into burst disaster, power failure, emergency power supply system is destroyed, and direction board still can maintenance work a period of time, and guiding crowd withdraws or evacuates.
Another example, one control module can be set, for controlling the accumulation of energy time of accumulation of energy layer, as shown in Figure 5, one control module 108 is set between light emitting module 107He supply line, by 108 surveillance conduction times of control module, system conduction time is the 1073 accumulation of energy time of accumulation of energy layer namely, when reaching the first Preset Time section, cut off the power supply of light emitting module, by accumulation of energy layer 1073, discharge energy-accumulating luminous, afterwards after the second Preset Time section, the power supply that recovers light emitting module 107, system power supply intermittent interruption, can reach energy-saving and cost-reducing object like this.
Should be understood that, for those of ordinary skills, can be improved according to the above description or convert, and all these improvement and conversion all should belong to the protection domain of claims of the present invention.
