a light emitting source 30, including a joint 31, at least one LED (not shown in the figure) installed in the joint 31, and a containing hole 32 formed at a position opposite to the LED and provided for containing the coupling portion 12 of the light guide strip 10; and
a controller 40, electrically coupled to the light emitting source 30, and including an upper casing 41 and a lower casing 42 engaged with each other, wherein the upper casing 41 and the lower casing 42 contains a battery 43 electrically coupled to a printed circuit board (PCB) 44 and a conductive plate 45, and a press button 46 penetrated through the upper casing 41, and provided for controlling an electric power source of the printed circuit board 44, and the printed circuit board 44 includes two electric wires 47 coupled to the joint 31 of the light emitting source 30, thereby the aforementioned elements constitute the sewable light guide device of the present invention.
When use (as shown in FIGS. 2 and 3), the joint element 20 is sewed or fixed onto a surface of an object (not shown in the figures) such as a bag, cloth or shoe, and provided for sewing the light guide strip 10 with a sewing edge or a strip line onto a surface of the object. During use, the coupling portion 12 of the light guide strip 10 is sheathed into the joint 31, and the press button 46 is pressed to turn on the LED in the joint 31 to emit light, such that the light of the LED can be guided along the spiral light guide etch mark 11 of the light guide strip 10 to emit light, so as to achieve the visually noticeable effect and a convenient application. If a cleanup is required, the coupling portion 12 of the light guide strip 10 can be detached from the joint 31 easily, and the controller 40 together with the light emitting source 30 can be removed to facilitate the cleanup of the object, so as to improve the convenience and safety.
In addition, the shape of the light guide strip, the light guide etch mark formed in the joint element and the shape of the light guide etch mark in the joint element can be changed according to the user's requirements.
With reference to FIGS. 4 and 5 for a preferred embodiment of the present invention, the light guide strip 13, 14 has a radial cross-section substantially a trapezium shaped strip (as shown in FIG. 4) or a rectangular shaped strip (as shown in FIG. 5), and the joint elements 21, 22 can be made of a translucent material, and the joint elements 21, 22 can be in a continuous or non-continuous form.
