Road indication device

Abstract: A road indication device is provided. The road-guidance indicating device has a light projection unit including light control means for controlling a lamp and light emitted from the lamp. The light projection unit project a light whose peak luminosity is 30000 cd or more, i.e., the light has a luminosity equal to or larger than a peak luminosity of a headlight of a car running on the road. Since a light pillar of light having a high light output and a thick light pillar is projected from the light projection unit, the visuality of the light pillar is improved even in the bad weather and the boundary between the driveway and the shoulder on the road can be affirmatively guided and indicated.

Intersection tail-pursuing lamplight controller

Abstract: The utility model discloses a lamp ornamental for the stage or in the handicraft article, in particular to a cross tailing light controller which can realize the light tailing effect The circuit structure of the utility model comprises a power circuit, a light control pulse generating circuit, a light control cross bilateral signal generating circuit, a generating and drive circuit of tailing effect and a voice control light passing circuit which controls the direction of the light The utility model applies voice and the ambient lamp light to control the light, as the intensity of the ambient light and the voice are arbitrary, the lamp light is also changed at random; therefore, the disadvantages of the normal light controller regulated by the program is solved In addition, the tailing effect is matched with the output circuit of the cross signal, thereby, during the flow of the light, a tailing effect of the light pillar is formed to make the light much more beautiful
