DETAILED DESCRIPTION

[0032] The present invention is further described in detail below in conjunction with the accompanying drawings, wherein the same components are represented by the same figure numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower", "bottom surface" and "top surface" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] Design concept: Design a dedicated full-color traffic induction screen, arrange the wiring harness of the LED module neatly, improve the heat dissipation performance, and reduce the thickness of the product.

[0035] Example:

[0036] like Figure 1-Figure 3 As shown, the technical solution of this product is: a full-color traffic induction screen, including an LED module 1, a power control box 2 and a main frame body 3, the LED module 1 is installed on the front of the main frame body 3, and the power control box 2 is provided at the bottom of the back, the power control box 2 is electrically connected to the LED module 1, and further includes a wiring groove 4 and an installation slide groove 5, a plurality of wiring grooves 4 are evenly arranged vertically on the back of the main frame body 3, and the inner grooves 43 face inwards; the installation slide groove 5 is further fixed on the wiring groove 4; the main frame body 3 and the wiring groove 4 are both galvanized sheet materials.

[0037] The wiring groove 4 of this embodiment includes a first wiring groove 41 and a second wiring groove 42, and the cross-sectional area of ​​the first wiring groove 41 is larger than that of the second wiring groove 42. There are three first wiring grooves 41, which are respectively arranged at both sides and the middle of the main frame body 3, and the second wiring grooves 42 are arranged between the first wiring grooves 41, and the mounting slide groove 5 is fixedly installed on the first wiring grooves 41.
