Description
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 component 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
Component, it is characterised in that：It is made up of hollow micro- shell (1) and fluorescent material (2), hollow micro- shell is white clear ball, and hollow
Micro- shell (1) is made up of glass or quartz；The external diameter of hollow micro- shell (1) is 0.5-1.5mm, its wall thickness≤0.5mm；It is described glimmering
Light powder (2) is powder structure, and enclosed package is in hollow micro- shell (1).
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 hollow micro- shell (1), thus
A comprehensive protective housing is formed outside fluorescent material (2).Also, hollow micro- shell (1) is made up of glass or quartz, materials
It is convenient, it is cheap, have the disadvantage that manufacture is relative complex.Also, glass or quartz construction intensity are high, and hollow micro- shell (1) is outer
Footpath is 0.5-1.5mm, its wall thickness≤0.5mm, and this actually forms a kind of micro-sphere structure, thus can further be made on the whole
Hollow micro- shell (1) has very high structural strength, is hardly damaged, so as to very effectively protect the fluorescent material (2) of inside,
Reliably fluorescent material is separated with dust and rainwater, environmental liquids, so as to prevent fluorescent material (2) runs into from reducing luminous effect after dust
Rate, and avoid fluorescent material (2) from running into rainwater or liquid, and then prevent 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 absorbed from all directions
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, two kinds
The mode that structure type absorbs luminous energy has essential distinction.In addition, this component is made up of two parts, simple in construction, novelty, tool
There is good practicality.
As prioritization scheme, the center of hollow micro- shell (1) is provided with a centre bore (1a), and the centre bore (1a) is used
Passed through in for threading.
A centre bore (1a) is designed in said structure, seems simple, takes a lot of learning actually, concrete reason is：Threading
, can be by several present invention strings together through after centre bore (1a)；Dry daytime or automobile is by causing during wind, wind
The present invention can be blown, so that the present invention rotates around threading or causes the present invention to rock, can thus make fluorescent material hollow
Fully, freely overturns or rock in micro- shell (1), so as to allow all fluorescent material in hollow micro- shell (1) more fully
Luminous energy is absorbed, and then absorbs enough energy.Dry in the evening or automobile is by causing during wind, and wind can also blow the present invention, from
And while allowing this case to send visible ray, can also rotate or rock around threading, effect is dynamically pointed out so as to reach, it is this dynamic
State prompting mode is not only more eye-catching than static state prompting, nor easily causes visual fatigue, so can further drop again
The probability of happening of low traffic accident, kills two birds with one stone.As fully visible, centre bore (1a) this technology is set although to be prior art,
But why the centre bore (1a) passed through for threading is set in the present case, it is that done under specific occasion special sets
Meter, achieves significant technique effect and with obvious substantive distinguishing features, therefore this design is also creative.
It is used as optimization design, the 1/3-2/3 of the cumulative volume duty heart micro- shell (1) cavity volume of the fluorescent material (2).Need
Special instruction, if the cumulative volume of fluorescent material (2) is very few, although can so improve the glimmering of unit volume to a certain extent
Light powder (2) absorbs luminous energy and luminous efficiency, but can influence total luminous quantity；If on the contrary, the cumulative volume mistake of fluorescent material (2)
It is many, 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, fluorescent material
The absorption luminous energy and luminous efficiency of unit volume can also be greatly reduced, and so the utilization rate of fluorescent material can be reduced again, so that in a disguised form
Cause part fluorescent material waste in ground.In addition, the cumulative volume of fluorescent material (2) is excessive, fluorescent material (2) can be also hindered in hollow micro- shell
(1) moved freely in.
In summary, the cumulative volume of fluorescent material (2), which just seems, is even more important, the cumulative volume of fluorescent material described in this case (2)
The 1/3-2/3 of the micro- shell of the duty heart (1) cavity volume, is the design made after thinking over, unit bodies has been taken into account well
The absorption luminous energy and luminous efficiency and total luminous quantity of product fluorescent material, effectively, compatiblely solve conflicting skill
Art problem, it is seen that this design is not belonging to routine techniques selection, is also not easy to be expected by those skilled in the art.
As optimization design, the external diameter of hollow micro- shell (1) is 1mm, and the wall thickness of hollow micro- shell (1) is 0.25mm,
Such external diameter and wall thickness can be effectively reduced manufacture difficulty, and take into account structural strength well.
Beneficial effect：The fluorescent material of the present invention is powder structure, and is encapsulated in hollow micro- shell of micro-sphere structure, this knot
Configuration formula can just protect fluorescent material well, effectively can not only prevent fluorescent material from failing, and can also make fluorescent material at utmost
Ground absorbs luminous energy and sends visible ray；Also, this case can be rotated or rocked with the wind when being through on threading, so not only more preferable
Ground improves the efficiency that fluorescent material absorbs luminous energy, and the visible ray sent can be rotated or rocked, and can thus play dynamic
Alarming effect, not only alarming effect is more eye-catching, and can be better protected from Driver Vision fatigue, more efficiently reduces
The probability of happening of traffic accident, can be used in the both sides in highway, highway, bridge and tunnel.
