Description
Technical field
The present invention relates to traffic signals field is and in particular to a kind of initiative luminescent traffic sign board and preparation method thereof.
Background technology
Traffic mark board is widely used to various highways, railway, harbour, viaduct, intersection, even occupies
People's cell, the information alert of traffic indication board and ensure personnel and the safety of locomotive facility.Existing traffic indication board is general
Do not light, be only pasted with reflective membrane, night carries out traffic prompting, this non-luminous reflection using the light reflection of vehicle
Traffic indication board due to can not actively light, light is dark, weather poor in the case of not easy to identify, carry to vehicle driver
Carry out very big inconvenience, or even traffic accidents can be caused.Therefore, minority producer is had to start from luminous traffic indication board,
In actual applications it has been found that existing illuminating traffic direction board has unreasonable structure, actively luminous lateral dispersion not
Uniformly, it is not easy to the shortcoming that driver is observed from different directions.
Content of the invention
The invention aims to overcome the deficiencies in the prior art it is proposed that a kind of new active luminescence scutcheon and its
Preparation method.
The present invention is achieved by the following technical programs:
A kind of active luminescence scutcheon, including hollowed-out board, backboard, connection strap and mounting bracket, described hollowed-out board is arranged on to be sent out
Before light label, centre is provided with traffic indication map case or the word of hollow out, is pasted with retroreflective film in place of vacancy section, described engraves
The hollow plate back side is connected with backboard by connection strap, is provided with mounting bracket after described backboard, described backboard and connection strap, hollow out
A luminescence unit is constituted, the bottom of described luminescence unit is provided with one layer of reflective membrane, and described reflective membrane is provided with one layer between plate
Even tabula rasa, described even tabula rasa sets several reflectors, and the center of described reflector is provided with led chip, and described reflector is pressed
Traffic indication map case on hollowed-out board or word arrangements, reflector is by conical section, little terrace with edge section, three sections of groups of big terrace with edge section
Become, described conical section is hemispherical, the radius of ball is 2-4 times of led chip radius, the incline of described little terrace with edge section and level side
To becoming 35-45 °, from the horizontal by 8-15 °, it is anti-that described reflector inner surface is coated with layer of metal to the incline of described big terrace with edge section
Penetrate film.
Further, the top of described luminescence unit and bottom are respectively equipped with led chip, described top led chip with
It is provided with light guide plate between the led chip of bottom.
The preparation method of above-mentioned active luminescence scutcheon is as follows:
The first step, makes several reflector moulds, and reflector mould is by conical section, little terrace with edge section, three sections of big terrace with edge section
Composition, described conical section is hemispherical, and the radius of ball is 2-4 times of led chip radius, the incline of described little terrace with edge section and level
Direction becomes 35-45 °, and from the horizontal by 8-15 °, described reflector inner surface is coated with layer of metal to the incline of described big terrace with edge section
Reflectance coating；
Second step, by reflector mould according to the traffic indication map case on hollowed-out board or word arrangements in transparent plastic
Or in glass material, even tabula rasa is cast as by heating；
3rd step, reflector mould is taken out from even tabula rasa, makes to be formed traffic indication map case or word shape on even tabula rasa
The hole of shape arrangement, hole becomes reflection cup-shaped, is then coated with layer of metal reflectance coating in reflector inner surface；
4th step, led chip is fixed in the reflector of even tabula rasa, and each led chip is connected with power supply；
5th step, makes hollowed-out board, backboard, connection strap and mounting bracket using aluminium alloy extrusions, glues in hollow out plate surface
Patch retroreflective film, on hollowed-out board and retroreflective film, hollow out goes out traffic indication map case or the word of needs；
6th step, pastes reflective membrane on backboard, installs even tabula rasa, then backboard is passed through connection strap with hollowed-out board even
Connect formation luminescence unit, and the led chip inlayed is made on traffic indication map case that hollow out on hollowed-out board goes out or word and even tabula rasa
The pattern being formed or word are corresponding, then load onto mounting bracket after backboard.
Beneficial effects of the present invention have:
The led chip of the present invention according to traffic indication map case or word arrangements on even tabula rasa, and pass through even tabula rasa
On reflector light line reflection and refraction are gone out, reflector is made up of conical section, little terrace with edge section, three sections of big terrace with edge section, light
Reflection and refraction repeatedly, are uniformly dissipated, this actively light homogenous diffusion mode be the present invention a great innovation, make
Driver can in the poor situation of daytime, night, weather, from different directions, difference from the point of view of on active luminescence scutcheon
Traffic indication map case or word.The lateral dispersion solving existing luminescence scutcheon is uneven, be not easy to driver from different
Direction carries out observing, easily cause the problem of break in traffic rules and regulations or even traffic accident.
The preparation method of the present invention is unique, can quickly form the band reflector by traffic indication map case or word arrangements
With the even tabula rasa of led chip, and active luminescence scutcheon is quickly assembled into by aluminium alloy extrusions, produces efficient and convenient, beautiful outline form
Sight, luminous dispersion effect are good.
