With the urbanization process over decades after the reform and opening up, the increase in vehicles enables traffic roads to be broadened significantly. The increase in vehicle types enables light reflecting marks and signs currently used as traffic signboards to be mounted at a quite high position above the roads, and generally they do not have a wide observation angle. When motor vehicles generally travel on an urban street, front lamps thereof have lamplight pointed downward, i.e. a low beam, and especially in an area having multiple lanes and large traffic flow, there is generally quite few amount of light emitted by the front lamps to point toward light reflecting marks and signs. Drivers cannot have a clear understanding when identifying and reading marks and signs. In an urban district, there are generally many street lamps, building illuminating and traffic signs beside traffic lights as well as neon lights, especially in rainy days and haze days, they severely interfere with the abilities of the drivers to see and read the marks and signs. In order to improve the abilities of the drivers to identify and read the marks and signs, the marks and signs should be provided with a ring illuminating light source and a wide incident angle illuminating light source.
The examples of existing signs being illuminated by independent illuminating light sources have: for example, lamps (generally fluorescent lamps) performing independent illumination at an angle in a near distance at an upper end of a sign; or illuminating light sources independently illuminating a guideboard at an angle in a near distance from underneath, characterized in that independent illuminating light sources are all mounted at an extension part on a post for fixing the guideboard. These illuminating sources and methods for illuminating a guideboard are all based on a JIS and Japanese guideboard installation standard regulations. Patent number: 95194507.6, 3M Corporation in America illustrates an example of an illuminating system for road signs, and although a point of a road sign illuminated by an illuminating source is updated and positioned, it is still characterized by illumination with an independent illuminating source. The guideboards illuminated by separate illuminating sources, under the action of a light reflection property, can only draw attention of drivers when they reaching a longer distance and a large visual angle range, but cannot be viewed clearly and easily read in a shorter distance because front lamp light sources of non-driving vehicles and front lamp light sources of driving vehicles collide with an incident angle of an independent illuminating source because of a light source incident angle.
The following technical disclosures are only about manufacturing refining of reflecting property, process and material: U.S. Pat. No. 4,726,134 (Woltman) discloses an improved roadway sign, in which light reflecting properties of mark and background parts on the surface of the sign are selected, so that the sign draws attention when being seen in a longer distance and is viewed clearly and easily read in a shorter distance. U.S. Pat. No. 4,957,335 (Kuney) discloses selecting a microsphere from a microsphere-based light reflecting object so as to improve the light reflecting brightness at a narrow observation angle. Japan Patent application No. 6-9426/94 (Nakajima) filed on Apr. 7, 1994 discloses a microsphere-based light reflecting plate, comprising two classes of microspheres for providing good light reflecting performances at a narrow observation angle and a wide observation angle.
It is difficult for optical bodies, which are transparent micro-spheres (beads) and light reflecting finished products thereof as the main technical representatives in the 90s in last century, to achieve a warning function in long-distance, large visual angle and weak light source environments in practical applications.
In addition, the motor vehicle warning marks (warnings sent by vehicles to front and rear directions), which are taken as the main technical representatives in nearly the hundred-year history, have hardly embody an omnidirectional warning function in crowded multiple lanes and large traffic flow.
Following a principles for a people oriented harmonious society, when considering enabling motor vehicles with an illuminating light source to obtain much more security and warnings, we should more provide comprehensive traffic indications of marks and signs and vehicle warnings for non-motor vehicles and pedestrians without an illuminating light source, and need a better illuminating system to enable traffic indications of marks and signs and vehicle warning devices, etc. to draw attention at a longer distance and within a large visual angle range, and to be viewed clearly and easily read in a shorter distance.
The present invention provides a mark and sign illuminating device and method, as well as a mark and sign illuminating system. The present invention is particularly applicable to a portable mark, a warning mark, a motor and non-motor vehicle warning mark, a traffic signboard, a billboard and other similar marks and signs.
The illuminating mark, sign and warning mark device system of the present invention comprises a mark and sign having a light reflecting sign surface transparent layer and an LED illuminating light source in an annular transparent layer, and with regard to the mark, sign and warning mark, an LED illuminating light source is placed in the transparent layer around the surface, so that light emitted from the light source is incident into the mark and sign surface transparent layer at an incident angle ranging from about 1 degree to about 179 degrees. The mark, sign and warning mark surface is a transparent layer with a thickness of 2-10 mm, the lowed end of the transparent layer is a light reflecting layer part, and this part has wide effective incident angles and wide light reflecting effective observation angles of the LED illuminating light sources.
The surface transparent layer of the mark, sign and warning mark and the light reflecting part at the lower end as well as an outer surface of the warning mark bottom board are provided with frame rims, inner sides of the frame rims have a light reflective material or a light reflective coating, the frame rims are packaged inward in a C shape, and a geometric prism layer or an arc-shaped reflecting sheet layer can exist in the inner sides of the frame rims. The LED illuminating light source in an annular transparent layer is incident into the mark, sign and warning mark surface transparent layer at an incident angle ranging from about 1 degree to about 179 degrees, the LED illuminating light source is comprehensively reflected through the light reflecting layer part at the lowed end of the transparent layer and the light reflective material, the light reflective coating or the geometric prism layer and the inner arc-shaped reflecting sheet layer, so that an LED illuminating comprehensive light source in the annular transparent layer of the mark, sign and warning mark is overlapped and incident into the light reflecting layer part at the lowed end of the surface transparent layer of the mark, sign and warning mark at an incident angle ranging from about 1 degree to about 179 degrees and is intensively reflected by the overlap incident angle via the light reflecting layer, so as to form wide effective reflection angles and observation angles, thereby drawing attention at a longer distance and within a large visual angle range.
Since an LED illuminating light source incident angle comprehensively reflected by the LED illuminating light source to the light reflecting layer part at the lowed end and the light reflective material, the light reflective coating or the geometric prism layer and the inner arc-shaped reflecting sheet layer via the transparent layer has no conflict with incident angles of high and low intensity light beams of lamplight of front lamps when a motor vehicle is travelling, personnel comprising the driver in the motor vehicle can pay attention to an object at a longer distance and within a large visual angle range, and can clearly view and easily read in a shorter distance; and since the LED illuminating light source is comprehensively reflected to the light reflecting layer part at the lowed end and the light reflective material, the light reflective coating or the geometric prism layer and the inner arc-shaped reflecting sheet layer via the transparent layer and is overlapped and incident at an incident angle ranging from about 1 degree to about 179 degrees so as to form wide effective intensive reflection angles and observation angles, this provides traffic indications of safety marks and signs and warning marks which focus on visuality for non-motor vehicles and pedestrians without an illuminating light source.
The LED illuminating lamp beads in the annular transparent layer are monitored by a CPU module, and when a problem occurs to a single LED illuminating lamp bead therein, the CPU monitoring module will timely drive reserved LED illuminating lamp beads to emit light. The CPU module monitors the whole device system circuit, comprising: electronic elements and components, such as a switch, a photosensitive sensing switch, a rain sensing switch, an infrared sensing switch, an ultrasonic sensing switch, a power supply module, a battery and a communication transmission module, and completes intelligent control over the mark, sign and warning mark lamp light and transmits, in real time, the data monitored by the CPU module.
The illuminating mark, sign and warning mark device and method and system of the present invention are suitable for the shape of large and small area, and flexibly employs mains power and electric energy generated by solar and wind, and matched mark, sign and warning marks are widely distributed and applied all over the world.
The present invention will be better illustrated with reference to the accompanying drawings:

In order to enable light of an LED illuminating light source from an annular transparent layer to be reflected by a light reflecting layer part so as to be seen by drivers and pedestrians, so that mark, signs and warning marks are more easily seen and read, the mark, signs and warning marks should reflect light at an observation angle, wherein when the observation angle is suitable for reflecting the light from an automobile front lamp with the brightness being greater than the LED illuminating light source in the annular transparent layer, light easily seen by an automobile driver and reflected by a light reflecting material is generally extended into a light cone observation angle pointing backward to a starting point of light rays; In addition, because the LED illuminating light source in the annular transparent layer is provided with overlapping incidence of incident angles ranging from about 1 degree to about 179 degrees, so as to form wide effective intensive reflection angles and observation angles, the drivers and pedestrians out of the observation angle ranging from about 1 degree to about 179 degrees pay attention when reaching a longer distance and a large visual angle range.
The present invention has one advantage of more easily identifying, seeing and reading a mark, a sign and a warning mark, changing a reflection establishment condition of reflective marks, and providing overlapping incidence of effective incident angles ranging from about 1 degree to about 179 degrees to a light reflecting layer part on a lower end of a mark, sign and warning mark transparent layer by an LED illuminating light source in an annular transparent layer on the mark, the sign and the warning mark.
