Panel display led active luminous and retroreflective interactive traffic sign board

Abstract

The invention discloses a panel display type LED active light-emitting and retro-reflection interactive traffic sign, comprising a sign component, a light-emitting component, a frame profile and a control component, wherein the sign component and the light-emitting component are connected by the frame profile; The sign board assembly includes a bottom-up backplane, a transparent PC board and a reflective film, and the reflective film is engraved with a hollow outline for displaying the text or pattern of the sign; the light-emitting assembly has a plurality of pieces. It consists of a light source board, which is attached to the backplane and is located between the backplane and the transparent PC board. The positive and negative poles of the light source board are connected in parallel; the light source board is reflow soldered with LED chip lamp beads, and the LED chip lamp bead array type has a rectangular shape Any one or more of , diamond or circle, the distance between the LED chip lamp beads and the reflective film is 25mm to 50mm. The traffic sign can emit light with uniform brightness and soft color in any external environment installed and used, and can avoid the generation of glare.

Description

technical field [0001] The invention belongs to the field of traffic sign boards, in particular to a panel display type LED active light emitting and retroreflection interactive traffic sign board. Background technique [0002] Traditional retroreflective traffic signs are passively reflective. In bad weather such as rain and fog and without lights at night, drivers and pedestrians cannot see the content of the signs clearly, and cannot take care of all road users. In addition, drivers at night must turn on high beams in order to see the content of distant signs clearly, and "high beams" are one of the major hidden dangers of traffic accidents at night, especially for opposite traffic without a central isolation belt. Therefore, the present invention designs a panel display type LED active luminous and retroreflective interactive traffic signboard. Contents of the invention [0003] In view of the above problems, the present invention proposes a panel display type LED act...
