Description

Technical Field

[0001] The utility model relates to the technical field of navigation lights, in particular to navigation lighting equipment. Background Art

[0002] The structure of existing navigation lighting equipment is as follows Figure 1 As shown, it consists of a light box, an isolation transformer, a primary cable, a primary cable connector, a light bulb and a lampshade, and is powered by 1kV AC.

[0003] like Figure 1 and 2 As shown in the figure, the existing wiring method of the isolation transformer requires opening a hole in the light box to connect two primary cable connectors. Since the light boxes are all set up in an outdoor environment, the aging of the primary cable head interface will affect the overall sealing protection level of the light box, and water vapor will enter the light box, affecting the service life of the equipment inside the light box; in addition, Figure 2 As shown, the existing primary cable is connected to the isolation transformer through a primary cable connector. The primary cable needs to be cut and connected to the isolation transformer at each isolation transformer, which results in a large workload for on-site construction. Utility Model Content

[0008] The through straight tube passes through and is fixedly connected to the light box;

[0009] A primary cable is arranged in the through straight tube, and the primary cable passes through the through straight tube from the outside of the light box to penetrate the light box and the iron core.

[0010] The following is a technical solution further defined by the present utility model, which also includes a light bulb, wherein the light bulb is located in a light box, and the light bulb is electrically connected to the secondary winding.

[0011] The following is a technical solution further defined by the present utility model, in which both ends of the straight through tube are respectively welded to the two side walls of the light box.

[0012] Compared with the prior art, the utility model has the following technical effects:

[0013] The utility model welds a straight tube through the light box and adopts a through-type isolation transformer, so there is no need to open a hole in the light box to install a primary cable connector, and there will be no aging problem of the primary cable connector, thus ensuring the sealing protection level of the light box; the primary cable is directly used to replace the primary winding, so there is no need to cut the primary cable during on-site installation, which reduces the workload of on-site construction and improves production efficiency.

[0022] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0024] like Figure 3-5 As shown, a navigation lighting device is provided, including a light box 1, an isolation transformer 2, a through straight tube 3, a primary cable 4, a bulb 5 and a lampshade.

[0025] like Figure 5 As shown, the isolation transformer 2 is in the form of a through-type. Figure 3 and 4 As shown, the iron core 201 and the secondary winding 202 of the isolation transformer 2 are arranged inside the light box 1, and there is no separately arranged primary winding; the primary side directly uses the primary cable 4, that is, the iron core 201 is outside the circumference of the through-through straight tube 3, and the through-through straight tube 3 is provided with the primary cable 4, and the primary cable 4 passes through the through-through straight tube 3 from the outside of the light box 1 and the iron core 201. Since the primary winding does not need to be separately arranged, the primary cable 4 does not need to be cut at each isolation transformer 2 when laying, which reduces the workload of on-site construction.

[0026] The two ends of the through straight tube 3 are respectively welded to the two side walls of the light box 1, so that the through straight tube 3 penetrates the light box 1. The through straight tube 3 is welded, eliminating the need to open a hole on the light box 1 for installing a primary cable connector, thereby ensuring the sealing protection level of the light box 1.

[0027] The bulb 5 is in the light box 1, and the bulb 5 is electrically connected to the secondary winding 202. The light generated by the bulb 5 passes through the lampshade to provide light navigation.
