Title:
LIGHT SOURCE SPLICING AND COMBINING TYPE ACTIVE LIGHT-EMITTING TRAFFIC SIGN
Document Type and Number:
WIPO Patent Application WO/2020/186720
Kind Code:
A1
Abstract:
A light source splicing and combining type active light-emitting traffic sign, comprising a surface light reflecting film (1) carved with a sign content hollow-out outline, a light transmitting panel, and at least one light source plate. Multiple LED lamp beads (9) are provided on the light source plate, and sliding blocks are provided on the back surface and/or the periphery of the light source plate. The sliding blocks stretch into a sliding rail (10) and are connected to a sectional material frame (7) in a sliding manner. The sliding blocks slide in the sliding rail (10) and drive the light source plate to move, so that the position of one light source plate or the position of a combined light source plate (6) spliced by multiple light source plates is adjusted to the position right opposite to the sign content hollow-out outline of the surface light reflecting film (1). The light source plate is detachably connected to the sectional material frame (7) by means of the sliding blocks and the sliding rail (10), and the convenience of maintaining and replacing a traffic sign light source plate is improved. The multiple light sources are spliced and combined into a combined light source so as to provide a light source for a device, a difficulty in mounting the traffic sign light source plate is lowered, the service life of the light source plate is prolonged, and the light source plate can be assembled and produced in a large-scale and standardized manner.
