Abstract
The utility model discloses a Light-Emitting Diode (LED) luminous signboard. The LED luminous signboard comprises a single LED light source, a reflective plate which is used for reflecting light emitted by the LED light source and a signboard which is provided with words or patterns. The LED luminous signboard is characterized by further comprising a light guide plate and a light diffuser plate. The light guide plate is arranged between the luminous panel and the signboard. The light diffuser plate is arranged between the light guide plate and the signboard. The LED light source is arranged in a reflection lampshade which is arranged on one side of the light guide plate. Due to the adoption of the single LED to give out light, cost is low and energy is saved. Due to the fact that the light guide plate and the light diffuser plate are utilized to enable the LED light source to give out the light which is changed from a point light source to a face light source, use ratio of the light source is improved, brightness of the light is increased and the light is enabled to be more soft and even. Due to the hollow words or patterns which are punched on a metal plate, a color contrast of the light diffuser and the metal plate are utilized, and the light diffuser and the metal plate extend outward to a hollow area, the LED luminous signboard takes on a metal effect.
