Detailed Description
The invention is further illustrated with reference to the following figures and examples:
the first embodiment is as follows:
the invention relates to a self-adaptive traffic light which comprises three lamp heads of red, yellow and green. In the first embodiment shown in fig. 1 and 2, each lamp head comprises a base shell 1 and a light source 2 arranged in the base shell 1, wherein the light source 2 is driven by a driving board 21 and generates a horizontal light beam emitted to the front; the front part of the base shell 1 is provided with a luminous panel 3 with light emitting holes 30 uniformly distributed on the surface, and the luminous panel 3 is composed of an optical atomization plate, such as an atomization acrylic plate; when the horizontal light beams irradiate on the light-emitting panel 3, the light-emitting panel 3 uniformly emits light; a control mechanism capable of controlling the longitudinal displacement of the light-emitting panel 3 is also arranged in the base shell 1; the traffic light also comprises a fog sensing mechanism; when the fog sensing mechanism senses a thick fog weather condition, the control mechanism controls the light-emitting panel 3 to move longitudinally to a second station as shown in fig. 2, and each horizontal light beam just emits from each light-emitting hole 30 on the light-emitting panel 3; in non-foggy weather conditions, the light-emitting panel 3 is moved longitudinally to the first station as shown in fig. 1, and the horizontal light beams are irradiated on the light-emitting panel 3 to make the light-emitting panel 3 emit light uniformly.
In the first embodiment, the light source 2 includes laser heads uniformly distributed on a vertical plane in the base housing 1, and each laser head generates one horizontal light beam. The laser head can also be replaced by a linear beam emitter consisting of a light-emitting diode with a reflecting cover and a condensing lens. A drain hole 10 is arranged at the bottom of the base shell between the light-emitting panel 3 and the light source 2 to drain accumulated water entering the base shell 1 through a light outlet 30 of the light-emitting panel 3.
In the first embodiment, the mist sensing mechanism includes a humidity sensor 4 disposed between the light source 2 and the light emitting panel 3 and above the inside of the base shell 1, and a fine mesh shell (not labeled) wrapping the humidity sensor; thus, in rainy weather, since rainwater is hard to enter between the light source 2 and the light emitting panel 3, the humidity sensor 4 can detect only a relatively limited humidity; in a foggy weather, the mist can enter the area between the light source 2 and the light-emitting panel 3 through the light-emitting holes 30 of the light-emitting panel 3, and the mist is condensed into water on the fine-pore reticulated shell, so that the humidity detected by the humidity sensor 4 is increased greatly, and the determination of the foggy weather is made. Compared with the traditional fog sensor, the fog sensing mechanism has higher accuracy because the detected humidity has sudden change characteristics in the thick fog weather; and traditional fog sensor judges environment fog concentration through the visibility, will receive the influence of camera lens pollution, rainwater interference scheduling problem, leads to its degree of accuracy comparatively limited.
In the first embodiment, the control mechanism includes an electromagnet 51 fixed to the base case 1 and disposed on the upper side of the light-emitting panel 3, and an armature 52 fixed to the upper edge of the light-emitting panel 3; the light-emitting panel 3 is constrained in a longitudinal chute provided in the base shell 1; when the electromagnet 51 is powered off, the light-emitting panel 3 is held downwards at the first station shown in fig. 1 under the action of self weight; when the electromagnet 51 is turned on, the light-emitting panel 3 is displaced upward by the magnetic attraction force and is held at the second position shown in fig. 2. The control mechanism is simple in structure and easy to realize.
In the adaptive traffic light, under a non-dense fog environment, the light-emitting panel 3 is kept at the first station, as shown in fig. 1, at this time, a horizontal light beam generated by the light source 2 irradiates the light-emitting panel 3, so that the light-emitting panel 3 uniformly emits light, and at this time, the display effect of the traffic light is consistent with that of a common traffic light; in a dense fog environment, as shown in fig. 2, the light-emitting panel 3 is kept at the second station, and at this time, each horizontal light beam is emitted from each light-emitting hole 30 on the light-emitting panel 3, so that light energy is concentrated in each horizontal light beam, and a colored light beam with a far range is formed in the air by the scattering effect of fog, so that the automobile can see the indicating state of the traffic light in a large range in the air at a far position; thereby being prepared in advance to improve traffic safety.
Example two:
for the second embodiment shown in fig. 3, the difference from the first embodiment is that: the fog sensing mechanism is an infrared transceiver 6 which is arranged on the base shell 1 and faces the ground; an infrared transmitting head in the infrared transceiver 6 transmits infrared signals to the ground at fixed time intervals; and the infrared receiving head in the infrared transceiver 6 receives the infrared signal reflected by the ground, and when the intensity of the reflected infrared signal received by the infrared receiving head is lower than a set value, the weather is judged to be thick fog. The infrared transceiver 6 of the second embodiment is available directly. Compared with the traditional fog sensor, the infrared transceiver 6 sends infrared signals to the ground, the intensity of the infrared signals reflected by the infrared transceiver is almost only influenced by the concentration of fog in the air (the water vapor can absorb a large amount of infrared radiation), and the infrared signals are slightly influenced by other conditions, for example, in rainy days, the rainwater lines usually have large intervals and do not obviously absorb the infrared radiation; therefore, the detection of the fog weather also has higher reliability.
Example three:
with regard to the third embodiment shown in fig. 4, it is different from the first embodiment in that the control mechanism includes the binding spring 7 provided on the upper side of the light-emitting panel 3, and the aperture-shaped light-transmitting layer 31 attached to the rear surface of the light-emitting panel 3; the light emitting hole 30 penetrates the light emitting panel 3 and the porous light transmitting layer 31; the porous light-transmitting layer 31 may be made of a transparent resin material through a foaming process; a pinhole layer with densely distributed fine holes can be directly pressed on the light-emitting panel 3 by adopting a needle plate to form the porous light-transmitting layer; the aperture-shaped light-transmitting layer may also be formed by forming a unidirectional or criss-cross groove layer on the back surface of the light-emitting panel 3 by a wire drawing process.
When the weight of the accumulated water on the surface of the aperture-shaped light-transmitting layer 31 does not exceed the design level, the light-emitting panel 3 is kept at the first station under the constraint action of the constraint spring 7; and when the weight of the water accumulated on the surface of the aperture-shaped light-transmitting layer 31 exceeds a design level, the light-emitting panel 3 is lowered to the second station by gravity. In general, when the ambient mist concentration is low, the light-emitting panel 3 has a high temperature due to the irradiation of the light source 2, and it is difficult to condense a large amount of water on the porous light-transmitting layer 31, and only when the ambient mist concentration reaches a high level, the accumulation rate of the amount of water on the porous light-transmitting layer 31 is greater than the evaporation rate, so that the large amount of water is condensed to promote the light-emitting panel 3 to descend.
For the third embodiment, the mist sensing mechanism and the control mechanism are simplified to the porous light-transmitting layer 31 and the restraining spring 7; the structure is greatly simplified, and the cost is greatly reduced.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, but rather as the subject matter of the invention is intended to cover all modifications, equivalents and alternatives falling within the spirit and scope of the present invention.
