Description

A kind of micro- shell combination of fluorescent material for highway, bridge or tunnel driving safety prompt

Technical field

The invention belongs to field of traffic, more particularly to a kind of fluorescence for highway, bridge or tunnel driving safety prompt The micro- shell combination of powder.

Background technology

With the development of society, traffic is more and more important, but traffic safety is one the problem of must not think little of, often The year traffic accident of whole nation generation causes mass casualties and property loss.Simultaneously as night sight is poor, so night is sent out The probability of raw security incident is significantly higher than daytime again, and the night on rainy day is easier occur traffic accident.In order to avoid night Generation traffic accident, typically can set the warning of suggesting effect in highway (particularly highway), bridge or tunnel both sides Lamp, these warning lamps reach prompting effect by way of active is luminous.However, warning lamp needs power consumption, not only need to set up Supply line, and need long-term consumption electric energy, in addition it is also necessary to periodic replacement and maintenance, cost are high.

Later, three kinds of safe driving prompting modes for replacing warning lamp are occurred in that again：The first is yellow black alternate plastics Band, when vehicle by when headlight be pointed on the plastic tape in front so that plastic tape is reflective, and then the width in promoting highway or tunnel Degree.The advantage of this prompting mode is that cost is low, it is not required that power consumption, more need not largely be repaired, and has the disadvantage that plastic tape reflects Light be usually gold-tinted, this gold-tinted is more dazzling, easily cause Driver Vision fatigue.

Second is the laying metal reflective mark on road surface, when automobile front lamp, which shines metal reflective, to be put on, metal Reflecting sign can illuminate road surface, and the advantage and disadvantage of this mode are identical with plastic tape.

The third is to use fluorescent material, and this mode scribbles fluorescent coating on the guardrail on both sides, and is applied in fluorescent material Layer surface is provided with one layer of wearing layer.Fluorescent coating absorbs too luminous energy daytime, and night actively sends visible ray, so as to reach safety The effect of prompting.The advantage of this mode is not need power consumption, and operation and maintenance cost is low, and the light sent is visible ray, and Cost is cheaper than warning lamp, but due to setting wearing layer so cost is than plastic tape and reflective absolute altitude；Have the disadvantage wearing layer wind After Exposure to Sunlight, wearing layer meeting aging comes off, and can thus expose fluorescent coating, and fluorescent coating surface roughness is larger, Run into the absorption luminous energy and luminous efficiency for being easy for significantly influenceing fluorescent coating after dust deposit；Also, fluorescent coating Would not occur after chance water or liquid, it is thus entirely ineffective.In addition, even if wearing layer does not wear and tear, existing fluorescence Powder coating is fixed and is coated on guardrail, and only the fluorescent material on surface can effectively absorb luminous energy, so in order to avoid waste of materials, Fluorescent coating can only be made than relatively thin, and so whether can all lighted whole night the problem of be also one very big；Gu also, The visible ray that fixed fluorescent coating is sent is also fixed, shows wide alarming effect also than relatively limited, if what is sent is visible Just move, alarming effect can be more preferable, also more not easily lead to visual fatigue, and existing stationary type fluorescent powder coating root Originally it can not realize.

The content of the invention

The technical problems to be solved by the invention be provide it is a kind of be not easy failure, with low cost, luminous efficiency it is high Fluorescent material spheroid, the fluorescent material glass marble can be used in highway, bridge or tunnel driving safety prompt, reduce the hair of traffic accident Raw probability.

Technical scheme is as follows：A kind of micro- shell of fluorescent material for highway, bridge or tunnel driving safety prompt Combination, it is characterised in that：It is made up of hollow micro- shell and fluorescent material, wherein hollow micro- shell is made up of glass or quartz；It is described hollow Micro- shell is white clear ball, and is made up of two hemisphere of the same size, leaves spacing between the two hemisphere, and two and half Ball is linked together by central shaft, and the inner chamber of two hemisphere is independent of one another；The external diameter of hollow micro- shell is 0.5- 1.5mm, its wall thickness≤0.5mm；The fluorescent material is powder structure, and enclosed package has a kind of hair in each hemisphere respectively Phosphor emission wavelength in the fluorescent material of ejected wave length, and two hemisphere is different.

In the above-mentioned technical solutions, in this case fluorescent material (2) has abandoned the coating structure in existing structure, is changed to freedom The powder structure of state, and the fluorescent material (2) of these free states is hermetically encapsulated in two hemisphere of hollow micro- shell (1) It is interior, comprehensive protective housing is thus formed outside fluorescent material (2).Also, hollow micro- shell (1) is made by glass or quartz Into convenient material drawing is cheap, has the disadvantage that manufacture is relative complex.Also, glass or quartz construction intensity are high, and hollow micro- shell (1) external diameter is 0.5-1.5mm, its wall thickness≤0.5mm, and this actually forms a kind of micro-sphere structure, thus can be on the whole Further make hollow micro- shell (1) that there is very high structural strength, be hardly damaged, so as to very effectively protect the glimmering of inside Light powder (2), reliably separates fluorescent material with dust and rainwater, environmental liquids, so as to prevent fluorescent material (2) from running into after dust Luminous efficiency is reduced, and avoids fluorescent material (2) from running into rainwater or liquid, and then prevents fluorescent material (2) from failing.

It should be strongly noted that in this case hollow micro- shell (1) external diameter be 0.5-1.5mm, its wall thickness≤0.5mm, There is special consideration, specific reason is as follows：1st, the structure of hollow micro- shell (1) is micro-sphere structure, and structural strength is very high；2nd, it is hollow micro- The size of shell (1) is small, and the surface area for so resulting in hollow micro- shell (1) is relatively large, so as to increase fluorescent material (2) and light Contact area, improves the extinction efficiency of fluorescent material (2)；3rd, in the manufacturing process of glass marble, hollow micro- shell (1) of small size is anti- And be more easily manufactured than large-sized hollow micro- shell (1), it thus can effectively reduce difficulty of processing and the manufacture of hollow micro- shell (1) Cost.

Meanwhile, hollow micro- shell (1) is white clear ball, and surface roughness is low, is so not only convenient for fluorescent material (2) transmission Hollow micro- shell (1) absorbs luminous energy or emitted beam, and hollow micro- shell (1) surface is difficult adhesive dust, so can enter one again Step improves the efficiency that fluorescent material (2) absorbs or emitted beam, and can also rinse out hollow micro- shell easily with water under high pressure (1) a small amount of dust of outer surface attachment, and without the hollow micro- shell (1) of fear of damage.In addition, hollow micro- shell (1) is white clear Ball, and fluorescent material (2) is powder structure, the organic cooperation of the two technical characteristics can be such that fluorescent material (2) is inhaled from all directions Receive luminous energy；Compared with traditional fluorescent coating, the efficiency of the fluorescent material absorption luminous energy of powder structure is greatly improved in this case, and two Planting the mode of structure type absorption luminous energy has essential distinction.Furthermore, hollow micro- shell (1) of this case is of the same size by two Hemisphere is constituted, and leaves spacing between the two hemisphere, and two hemisphere are linked together by central shaft, and two hemisphere is interior Chamber is independent of one another.The effect of central shaft, which is not only, links together two hemisphere, and can be outside central shaft when using A snap ring is cased with, snap ring coordinates with central axis, and the present invention can thus acted in wind caused by natural wind or vehicle It is lower to rotate, the fluorescent material in two hemisphere can thus fully, freely overturn, owns so as to allow in hollow micro- shell (1) Fluorescent material more fully absorb luminous energy, and then absorb enough energy.Dry in the evening or automobile is by causing during wind, wind Also the present invention can be blown, so that while allowing this case to send visible ray, can also rotate, effect is dynamically pointed out so as to reach, this Plant dynamic reminding mode not only more eye-catching than static state prompting, nor easily cause visual fatigue, so again can be further Ground reduces the probability of happening of traffic accident, kills two birds with one stone.Further, enclosed package has a kind of transmitting in each hemisphere Phosphor emission wavelength in the fluorescent material of wavelength, and two hemisphere is different, and fluorescent material in two hemisphere can thus sent Visible light colors it is different, this aberration is organically combined with dynamic alarm function, can further increase dynamic warning Effect, the effect of everybody killing three birds with one stone.As fully visible, set this technology of central shaft to seem simple, be under specific occasion The particular design done, achieves significant technique effect and with obvious substantive distinguishing features, therefore this design also has It is creative.

In the present case, the fluorescent material cumulative volume in each hemisphere accounts for the 1/3-2/ of the hollow micro- shell cavity volume of correspondence 3。

It should be strongly noted that if the volume of fluorescent material (2) is very few, although can so improve list to a certain extent The fluorescent material (2) of position volume absorbs luminous energy and luminous efficiency, but can influence total luminous quantity；If on the contrary, fluorescent material (2) Volume is excessive, although can so improve the total luminous quantity of fluorescent material (2) to a certain extent, it is ensured that can light the whole night, The absorption luminous energy and luminous efficiency of fluorescent material unit volume can also be greatly reduced, and so can reduce the utilization rate of fluorescent material again, from And in a disguised form cause part fluorescent material waste.In addition, the volume of fluorescent material (2) is excessive, fluorescent material (2) can be also hindered hollow micro- Moved freely in the hemisphere of shell (1).

In summary, the volume of fluorescent material (2), which just seems, is even more important, and the fluorescent material in this case in each hemisphere is total Volume accounts for the 1/3-2/3 of the hollow micro- shell cavity volume of correspondence, is the design made after thinking over, list has been taken into account well The absorption luminous energy and luminous efficiency and total luminous quantity of position volume fluorescent material, effectively, compatiblely are solved conflicting Technical problem, it is seen that this design be not belonging to routine techniques selection, be also not easy to be expected by those skilled in the art.

As the important decision design of this case, the phosphor emission wavelength in the hemisphere is 500-560 nanometers, Phosphor emission wavelength in another described hemisphere is 605-700 nanometers.

In said structure, launch wavelength is that the visible ray that 500-560 nanometers of fluorescent material is sent is green glow, launch wavelength The visible ray sent for 605-700 nanometers of fluorescent material is feux rouges, and the penetration power of feux rouges is strong, eye-catching, dazzling, and green glow penetration power It is weaker, soft, it is difficult to allow driver to produce visual fatigue, the very big visible ray collocation of both aberration is together, simultaneous well Turned round and look at penetration power, it is eye-catching and avoid visual fatigue, can further improve alarming effect, and this case both colors when rocking Visible ray collocation together alarming effect it is more obvious.

As important decision design, the diameter of the central shaft is the 15%-20% of hollow micro- shell external diameter.

In said structure, if the ratio between the diameter of central shaft and hollow micro- shell external diameter is too small, although can reduce Manufacture difficulty, but structural strength can be effectively reduced, and unstability when this case is rocked can be increased；If the diameter of central shaft Ratio between hollow micro- shell external diameter is excessive, although can effectively improve structural strength, and when can increase this case and rocking Stability, but manufacture difficulty can be reduced again.As fully visible, organically, harmony the problem of the two are conflicting is solved Compare intractable, the ratio selected in this case is moderate, the demand of two aspects has been taken into account well, be both not belonging to routine techniques choosing Select, be not easy to be readily apparent that by those skilled in the art again.

The external diameter of hollow micro- shell is 1mm, and the wall thickness of hollow micro- shell is 0.25mm, and such external diameter and wall thickness can have Effect ground reduction manufacture difficulty, and structural strength is taken into account well.

Beneficial effect：The fluorescent material of the present invention is powder structure, and is individually enclosed in hollow micro- two, shell of micro-sphere structure In hemisphere, this structure type can just protect fluorescent material well, effectively can not only prevent fluorescent material from failing, and can also make glimmering Light powder farthest absorbs luminous energy and sends visible ray；Also, the central shaft of this case can make the present invention with the wind rotate or Rock, so not only preferably improve the efficiency that fluorescent material absorbs luminous energy, and the visible ray sent can be rotated or rocked, this Sample will play dynamic alarming effect, and not only alarming effect is more eye-catching, and it is tired to be better protected from Driver Vision Labor, more efficiently reduces the probability of happening of traffic accident；In addition, the phosphor emission wavelength in two hemisphere is differed, this Sample will send two kinds of different visible rays, so as to further improve alarming effect, further reduce the generation of traffic accident Probability, can be used in general urban highway, highway, bridge and tunnel.
