Hanging luminous frame of a traffic sign plate

摘要

A hanging luminous frame of a traffic sign plate includes elementary frame sections, each being a long hollow enclosure which defines a luminous frame surface and a concave back side, wherein the concave back side is to be supported against the marking surface of the traffic sign plate. Connecting edges allow the elementary frame sections to be connected to each other and form a frame. Luminous through holes are distributed over the luminous frame surfaces. Waterproof transparent covers have a housing enclosure part, a transparent covering part and a fitting and positioning part. LED lighting components have a circuit base plate, LED components and conductor wires, wherein the LED lighting component is held inside the waterproof transparent cover. A waterproof layer is filled in the housing enclosure parts to seal the inside circuit base plate. Positioning and reinforcing edges provide a stable locking interface for the locking and positioning component.

1. An improved structure of a hanging luminous frame of a traffic sign plate; said hanging luminous frame is to be fitted on the peripheral area of the marking surface of the existing traffic sign plate, so as to realize the illuminating function; the hanging luminous frame comprises:
a plurality of elementary frame sections, each elementary frame sections is a long hollow enclosure which defines a luminous frame surface and a concave back side, wherein the concave back side is to be supported against the marking surface of the traffic sign plate; connecting edges, configured on the two opposite extending ends of each elementary frame sections, so that the elementary frame sections can be connected to each other through the connecting edges and form a preset frame; a plurality of luminous through holes, distributed over spaced intervals on the luminous frame surface of each elementary frame sections; a plurality of waterproof transparent covers, each waterproof transparent cover comprises a housing enclosure part, a transparent covering part and a fitting and positioning part, wherein the housing enclosure part comprises an end wall and a circular side edge to form a housing space, and on the opposite side of the circular side edge, an LED mounting opening is formed; the transparent covering part is in the shape of a hollow enclosure, protruding from the end wall of the housing enclosure part, and the transparent covering part can transmit lights; the fitting and positioning part is integrally formed on the outside of the housing enclosure part or the transparent covering part, and the fitting and positioning part is properly shaped so that it can be fitted on the luminous through hole; a plurality of LED lighting components, each LED lighting component comprises a circuit base plate, an LED component and several conductor wires, wherein the circuit base plate is held inside the housing enclosure part of the waterproof transparent cover, the LED component is held inside the transparent covering part of the waterproof transparent cover, and the conductor wires extend from the circuit base plate; waterproof layer, filled inside the housing enclosure part of each waterproof transparent cover, to seal the inside circuit base plate so as to prevent the inside circuit base plate and LED components from getting wet; positioning and reinforcing edge, formed in an extending style on preset positions of each elementary frame sections, each positioning and reinforcing edge is to provide a firm locking interface for a locking and positioning component.
