Description
Technical Field
The utility model relates to a traffic sign technical field specifically is a combined material traffic sign tablet that has spontaneous light and reflection function concurrently.
Background
The road traffic sign is a graphic symbol for displaying traffic laws and regulations and road information, and can make the traffic laws and regulations be visually, specifically and concisely expressed, and at the same time express the contents which are difficult to be described by characters, and can be used for managing traffic and indicating driving direction to ensure the facilities of road smoothness and driving safety.
The traditional traffic sign board reflects light passively under the condition of light source irradiation, and plays a role in visual identification. The distance for visual recognition depends on the illumination intensity of the light source, whereas the traffic sign does not emit light in the absence of illumination by the light source. Under severe weather conditions, drivers must use high beam lights to see the contents of the traffic sign clearly. However, when the strong light emitted by the high beam illuminates the eyes of the driver or the pedestrian, the glare can make the eyes of the driver or the pedestrian instantly painted black, and the reaction time and the braking distance are increased by nearly one time. According to the relevant data, 40% of traffic accidents are related to high beam. There is a need to develop an active light emitting and retroreflective interactive traffic sign.
The existing self-luminous traffic sign board on the market has the following defects:
1) because the LED lamp is arranged behind the signboard, although the LED lamp has high light intensity and high eye-catching degree, and also has the functions of path induction and intelligent traffic indication, the driver can feel discomfort due to glare when directly seeing the front, and the back is fully covered with a large number of light sources, so that the cost is high, the energy consumption is high, and the LED lamp does not meet the requirements of energy conservation and emission reduction.
2) The reflective materials on the back bottom all adopt Fresnel prism reflective films, hollow characters or patterns adopt light permeable reflective films, and the transmittance of the reflective films has high requirement on self-luminous power, so that high energy consumption is caused.
3) The LED array is used for direct projection, patterns and characters are directly displayed, and the sign board has higher brightness, can generate dazzling feeling to a driver and influences safe driving.
4) The steel plate is made by self-luminous technology, solar energy or commercial power is directly adopted to supply power to the steel plate without any bulb. The luminous steel plate can work under any severe weather conditions, maintenance is not needed, and the service life of the luminous steel plate can reach 20 years. The luminescent material of the steel plate is a luminescent element which is manufactured by fusing the luminescent material and the molten steel plate together at high temperature and cooling. Weather resistance is the same as that of a steel plate, and self-luminescence is realized, so that the steel plate has many advantages such as: portable, built-in lithium cell, high visibility. However, the steel plate material has a large specific gravity, the composite material has a high cost, and the energy storage problem is also existed.

The resin scattering film is prepared by taking polyethylene terephthalate as a matrix and linear low-density polyethylene and spherical organic silicon resin particles as disperse phases through a melt blending method.
Furthermore, the reflective film is a white reflective film special for traffic.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model provides a have self-luminous and reflection function's combined material traffic sign tablet concurrently, the self-luminous and the retro-reflection light of the positive fretwork characters or pattern of light guide plate come from the stromatolite combined material that has scattering and reflection function concurrently of light guide plate bottom. The utility model discloses a traffic sign tablet has compensatied traditional reflection of light traffic sign because of the night visibility that causes by the ambient light influence is poor, distinguish difficulty etc. not enough, has great help to receiving the use of the great highway section of ambient light influence, crossing traffic sign, has strengthened the security that the driver drove driving at night greatly. Adopt special material's scattering-reflection complex film to make the utility model discloses a traffic sign board can be at the even, the color and luster of the light luminance that any external environment of installation used sent, can avoid the production of glare. The utility model discloses reduce the material cost of spontaneous light power and reduced the energy consumption to the weight of traffic sign board self has been reduced.
