Embodiment Construction

[0011] Such as figure 1 The schematic diagram of the structure of the passive light-emitting street sign shown is a passive light-emitting street sign, which includes a road information sign body 1, a solar power generation system 3, a noise generator 4 and a storage battery 5, and the road information on the sign body 1 is provided by the LED The lamps are arranged in 2 arrangements. Such as figure 2 As shown in the schematic diagram of the connection of each component, the solar panel and the noise generator 4 in the solar power generation system 3 are connected in parallel. Converted into electric energy, the two provide storage electric energy to storage battery 5 jointly. At night or when the light is dark, the light control switch 6 is closed, so that the series loop formed by the storage battery 5 and the LED light 2 is connected, and the LED light 2 works normally, clearly indicating road information for people.

Abstract

The invention relates to a passive luminous guideboard. Road information characters on a signpost body are formed by arranging light-emitting diodes (LED); a solar cell panel in a solar power generation system is in parallel with a noise generator; and the output is connected with a storage battery which is used for supplying power to the signpost body through an optical control switch and is arranged at the top of the road information signpost body. The passive luminous guideboard is high in working stability and can provide clear road information for pedestrians at nights; the solar light intensity is strengthened through a convex lens arranged above a solar panel by utilizing the light condensing function, so that the power generation amount of the solar cell is increased in the unit area; and noise generated by passby vehicles on the road or a peripheral noise source is utilized to generate power, so that harmful noise can be transformed into electric energy which can be stored in the storage battery through the noise generator arranged at the bottom of the signpost for the LED to use, thereby achieving the energy-saving effect.

Description

technical field [0001] The invention relates to a road sign, in particular to a passive luminescent sign. Background technique [0002] Road information signs are widely used in urban road instructions to provide people with road names and road directions. However, at present, the road signs set on the road are mostly sprayed with fluorescent powder on the signboard. At night, it is necessary to use the reflected light of the fluorescent powder to see the road information clearly. This kind of signboard can be seen clearly during the day, but it appears blurred at night. Clearly, if the driver does not see the instructions on the sign at this time, it will cause more walking due to wrong roads, which will not only waste energy virtually, but also increase potential traffic risk factors. Although there are many solar luminous street signs at present, the power generation of solar cells per unit area often does not reach the designed value, which reduces the effective utiliza...
