Movable light-guide fiber display

Abstract

The invention discloses a movable light-guide fiber display which structurally comprises a handle, a control switch, a movable box and a display screen. The movable box is provided with a light sourceplate, a fixed plate, a scaling mechanism and a transparent plate. A pressure block in a blocking mechanism is scaled through a controller in a telescopic device, when a telescopic mechanism is retracted, a bent rod is stressed and bent inwards to block light, so that the irradiation range in an irradiation hole is prevented from being too dense, the intensity of the light is adjusted, the diffraction phenomenon caused by too dense irradiation is avoided, and the visual effect at the edge of the pattern is prevented from being influenced by light cross; and the refractivity of a light sourceemitted by a bent mirror is controlled, so that light rays are in a good uniform scattering state, the light rays are prevented from forming a cross phenomenon, the light rays enter a reverse transparent mirror in a scattering structure and are refracted and diffused from rhombic holes after being focused, the light rays reach a uniform state, light sources are scattered orderly, and the problem of non-uniform brightness caused by scattering deviation is solved.

Description

technical field [0001] The invention relates to the field of optical fiber equipment, in particular to a movable optical fiber display. Background technique [0002] Store the electric energy of the solar cell in the accumulator, use the electric power to make the LED emit light, use the optical fiber to guide the light to the display panel, and draw characters and graphics in the form of a dot matrix on the front surface of the optical fiber. In order to improve the visual roundness between the graphics, the blank area between the light source points is small, because the size of the light source point structure is not easy to expand and shrink, resulting in too dense light source points of the same size, resulting in light diffraction phenomenon, resulting in pattern distortion It is not clear, so that the visual effect at the edge of the pattern is poor, and the irradiation direction of the light in the process of dot diffusion is in a scattering state. Due to the interse...

In order to improve the visual roundness between the graphics, the blank area between the light source points is small, because the size of the light source point structure is not easy to expand and shrink, resulting in too dense light source points of the same size, resulting in light diffraction phenomenon, resulting in pattern distortion It is not clear, so that the visual effect at the edge of the pattern is poor, and the irradiation direction of the light in the process of dot diffusion is in a scattering state. Due to the intersection phenomenon of light spot expansion during irradiation, the radiation is irregular, and deviations are likely to occur, resulting in Phenomenon that the brightness is too dazzling and too dark
