Description

The long-persistence luminous label that LED excites

Technical field

The utility model relates to long-persistence luminous label, particularly relates to the long-persistence luminous label that a kind of employing LED (semiconductor light-emitting-diode) excites.

Background technology

Rare earth long-afterglow luminescent material is owing to have light-accumulated luminous function, behind the visible light or ultraviolet light of absorption about 5～15 minutes, can in the dark continue luminous more than 5～10 hours, be widely used in the guide sign aspect in civil administration, petrochemical industry, fire-fighting, real estate, maritime affairs, military affairs, advertising lamp industry and field, because it has does not need electric wiring, can recycle, energy-efficient advantage, has very strong competitive edge on market.But, rare earth luminescent material also has some shortcomings, having hindered it further promotes the use of, the one, must there be the exciting just of light of sufficient intensity can make the long after glow luminous material accumulation of energy, and in a lot of relatively darker places, such as satisfying this condition in dark corridor, underground parking, bombproof, the mine.Secondly, present long after glow luminous material light decay compares comparatively fast, and the long afterglow brightness after half an hour can't have been satisfied the higher occasion of ask for something sign brightness.If allow long after glow luminous material play a role, what enough brightness must be set around the material excites the cold light light source, can adopt electricity-saving lamp, daylight lamp (fluorescent light) etc., but just greatly reduce the advantage of long after glow luminous material like this, increase cost, also strengthened the difficulty of safeguarding.

In recent years, the led light source that high brightness occurred, that led light source has is low in energy consumption, volume is little, thermal value is low, driving voltage is low and advantage such as long service life, and aspect emission wavelength broad covered area, can cover from the scope of green glow, blue light, purple light and even white light.

The utility model content

Technical problem to be solved in the utility model provides a kind of long-persistence luminous label, and this label adopts LED to excite, can be luminous for a long time.

The technical scheme that the utility model technical solution problem is adopted is: the long-persistence luminous label that LED excites, comprise long-persistence luminous label, described long-persistence luminous label comprises light conductor and the literal or the pattern that are arranged on the light conductor, and described long-persistence luminous label is provided with at least one led light source.

The beneficial effects of the utility model are: the utility model makes full use of the light-accumulated luminous characteristic and the led light source emitting characteristics of long after glow luminous material, makes the long after glow luminous material line that can emit a brilliant light for a long time.In order further to bring into play long-afterglow material long characteristic after time, the utility model adopts to led light source and powers discontinuously, allow led light source light a few minutes earlier, the light that led light source sends make long after glow luminous material hold light saturated after, automatically cut off power supply, utilize the electric power storage characteristics of luminescence of long afterglow to continue more than 10～30 minutes then, after the long-afterglow material decay of luminescence arrives to a certain degree, tdm controller restores electricity again, allows led light source excite for the long-afterglow material accumulation of energy.Circulation had so repeatedly both guaranteed that long-afterglow material keeps enough brightness, can save the energy again greatly.

Embodiment

Long-persistence luminous label of the present utility model comprises light conductor 2 and the literal or the pattern 1 that are arranged on the light conductor 2, also is provided with at least one led light source 3 on long-persistence luminous label.

As shown in Figure 1, preferably be connected with led driver 6 on the led light source 3, with the steady operation of control led light source 3; Also preferably be connected with LED tdm controller 7 on the led light source 3, to light the intermittence of control led light source 3 and to extinguish; The rechargable battery 4 that also preferably is connected with governor circuit 5 and communicates on the led light source 3 with governor circuit 5.

In order to make compact conformation of the present utility model, preferably all component of the present utility model is installed on the tank bracket 10, hanging apparatus 8 is provided with for convenience of installations of the present utility model.

Led light source 3 can adopt LED bulbs such as green, blueness, purple, ultraviolet ray, white, and the LED bulb can serial or parallel connection, but preferably adopts cascaded structure.

Literal that long after glow luminous material is made or pattern 1 can be to be printed on the light conductor 2, also can be that the sticking to mould that luminescent material is made sticks on the light conductor 2, can also be that the filling luminescent material forms literal or pattern 1 after engraving or etching on the light conductor.

Light conductor 2 adopts the higher materials such as clear glass, polycarbonate plate (PC plate) or poly-methyl-prop methyl esters (PWMA) plate of transmittance to make, and in the higher occasion of fire protection requirement, preferably adopts flame resistant glass to make.

Fig. 2 is a work block diagram of the present utility model, and when external power supply had electricity, governor circuit 5 one sides and rechargable battery 4 is charged directly controlled tdm controller 7 on the other hand; After externally fed is ended, governor circuit 5 is opened the power supply passage of battery 4, give tdm controller 7 power supplies, tdm controller 7 gives led light source 3 power supplies off and on, make led light source 3 intermittently light and extinguish, periodically literal and the pattern 1 that luminescent material is made excites, and keeps luminescent material to continue to launch bright light.

In order to increase light luminance, the utility model can also stick reflective membrane 9 in the side of light conductor 2, be used for the light that to go out from light conductor 2 sides reflected back light conductor 2 again, light is through repeatedly reflecting and reflecting, evenly (literal and pattern 1 place face) penetrates from light conductor 2 fronts, thereby makes the brightness of literal and pattern 1 higher.

In actual applications, the top of the framework 10 among Fig. 1 is preferably made hollow structure, and led driver 6, LED tdm controller 7, governor circuit 5 and rechargable battery 4 are provided with wherein, does not externally observe, and is not only attractive in appearance but also be convenient to protect.

Led driver 6 of the present utility model, LED tdm controller 7 and governor circuit 5 can adopt present prior art.
