Detailed Description

In order to further understand the present invention, the following description specifically exemplifies preferred embodiments of the present invention and describes the constituent contents and intended functions of the present invention in cooperation with the attached drawings.

For convenience of illustration, the drawings are only schematic to facilitate understanding of the present invention, and the detailed proportions can be adjusted according to design requirements. The above and below description of the relative devices in the figures, which will be understood by those skilled in the art as referring to the relative positions of the objects, can be turned over to present the same elements, and all should fall within the scope of the present disclosure, which will be described in the specification.

Referring to fig. 1, a cross-sectional view of a light-emitting water-cooled tube device according to an embodiment of the present invention is shown, as shown in fig. 1, a light-emitting water-cooled tube 1 includes a water-cooled tube 10, the water-cooled tube 10 is covered by a light guide material 12, a light mixing region 14 is further disposed below the water-cooled tube 10, wherein the light mixing region 14 is a protruding portion formed by the light guide material 12, a hollow region is formed in the center of the light mixing region 14, a light-emitting device 16 (such as a light-emitting diode or the like) is included in the light mixing region 14, the light mixing region 14 functions to provide a sufficient space, so that light 18 emitted by the light-emitting device 16 is reflected in the space and then transmitted to the light guide material 12, and thus light displayed by the light guide material 12 is uniform.

However, the luminescent water-cooling tube shown in fig. 1 also has some disadvantages, and firstly, the light-mixing region 14 protrudes out of the surface of the light guide material 12 to occupy too much space, which is not favorable for reducing the size of the device. Further, the structure of the light mixing region 14 causes the bending angle of the whole light-emitting water-cooling tube 1 to be limited, and taking fig. 1 as an example, the light-emitting water-cooling tube 1 may be bent only in the X-axis direction, while the bending in the Y-axis direction will be limited due to the presence of the light mixing region 14. In addition, since the light 18 is reflected in the light mixing region 14 and then enters the light guide material 12, if the water cooling tube 10 is made of an opaque material (e.g., black), a part of the light 18 will be blocked, so that a dark region is generated in the light emitting water cooling tube 1 visually.

Please refer to fig. 2, which illustrates a schematic diagram of a light emitting device according to the present invention. As shown in fig. 2, the light emitting device 2 of the present invention includes at least one light guide 20, at least one light emitting device 22 and at least one attaching device 24. Taking fig. 2 as an example, the light guide 20 preferably includes a strip structure similar to a tube with an opening.
