LIGHT EMITTING DIODE (LED) MARKING PANEL
First Claim
1. A light emitting diode (LED) marking panel, comprising:
- a substrate, being comprised of a plate with a thickness and a shape defining a marking surface and a back surface;
a protruding flange, being protruded on a periphery of the marking surface of the substrate;
a recessed space formed on the marking surface of the protruding flange;
a plurality of LED units, arranged at intervals on the marking surface of the substrate, and electrically connected via conductor wire;
a transparent waterproof layer, being formed by a transparent waterproof agent filled into the recessed space of the protruding flange, said transparent waterproof layer fully covering the LED units and conductor wire, light emitted from LED units being released from the transparent waterproof layer; and
a chromogenic layer, attached onto the transparent waterproof layer and defined with preset shape and color, the light emitted from LED units passing through the chromogenic layer.

Abstract
The present invention provides a light emitting diode (LED) marking panel, including a substrate, which forms a marking surface; a protruding flange, which is protruded on the periphery of the marking surface of the substrate; and a recessed space is formed internally onto the protruding flange. Multiple LED units are arranged at intervals on the marking surface of the substrate and electrically connected via conductor wire. A transparent waterproof layer is formed by a transparent waterproof agent that is filled into the recessed space of the protruding flange. A chromogenic layer, attached onto the transparent waterproof layer, is defined with preset shape and color, such that the light emitted from LED units can pass through it. The LED units and conductor wire feature excellent waterproofing with the covering of the transparent waterproof layer, and the LED marking panel can be used more robustly and durably with much longer service life.
