DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
An LED (Light-Emitting Diode) lamp bank of the present invention allows an LED lamp bank 1 to connect with each other with a male connection terminal 2 to achieve effects of an easy implementation and beauty. Referring to FIG. 4, left and right end sides of the LED lamp bank 1 are provided with a same amount of female power socket holes 12 as that of the male connection terminals 2. In the drawing, there are four female seat holes 12, with each of which being provided with a positive and a negative electrode.
The male connection terminal 2 is provided with at least two-way pins 21 which can be inserted into the female socket holes 12 of the LED lamp bank 1, such that two LED lamp banks 1 can be connected serially by the two-way pins 21. Therefore, if a plurality of LED lamp banks 1 need to be connected serially, these male connection terminals 2 can be used to transmit power. By this design, in connecting the LED lamp bank 1 serially, as both ends of the bank are provided with the female socket holes 12 for connecting with the male connection terminals 2, there will be no limitation to directionality as in the prior art, and any end can be used for connection freely. In addition, it is not easy to result in a short-circuiting phenomenon from being stained with moisture during implementation.
On the other hand, the LED lamp bank 1 of the present invention is provided with a structure which is basically the same as that of the prior art, and includes the aforementioned soft substrate 16, conduction wires 18, LED lamps 13, and soft vinyl 17 which encloses at the exterior. In order to increase strength at a location of the LED lamp 13, a hard protective sheet is specifically installed at that location. Referring to FIG. 8, it shows a cross-sectional view of an LED lamp bank formed with a surface mounted technology. A hard protective sheet 40 is located below a protective pad 19 which holds the soft substrate 16, at the location of the LED lamp 13. This hard protective sheet 40 can exactly cover an area of the LED lamp 13, and therefore, even that when the LED lamp bank 1 is bended, it will not be bended at a range of the LED lamp 13, but over a region of the hard protective sheet 40, thereby preventing from a danger of fracture at the LED lamp 13, which serves as the bending location.
Referring to FIG. 9, it shows a schematic of an embodiment that the hard protective sheet 40 is located on the LED lamp 13, wherein the hard protective sheet 40 is provided with a closed holding space 40A for exposing the LED lamp 13, as shown in FIG. 10. Of course, the hard protective sheet 40 can be also designed to have an open holding space 40B, as shown in FIG. 11.
Other element that is related to the LED lamp 13 includes a resistor 14. If the bending of the LED lamp bank 1 will reduce a cross-sectional area of a soft vinyl where the related element is located, then it should also be covered by an area of the hard protective sheet 40.
Furthermore, referring to FIG. 14, it shows a schematic of an embodiment of a two-pin LED lamp, wherein a hard protective sheet 41, which is provided with a holding space, is located on a position of the LED lamp 13. As shown in FIG. 15, the holding space is in a shape of a concaved part 42, and the pins of the LED lamp 13 can be sheathed in at positions of the soft substrate 16 to be covered in a front and a rear, so as to strengthen the position of the soft vinyl 17 where the LED lamp 13 is located. Therefore, when the LED lamp bank is bended, that position will not be bended directly due to a protection of the hard protective sheet 41, thereby preventing from an ill condition of the prior art that the LED lamp bank is easily fractured at the location of the LED lamp 13.
The hard protective sheet 41 is not limited to the concaved shape, but can be also in a plate shape to be located at a periphery of the LED lamp, as long as that it can protect the LED lamp from being bended easily.
In installing the above hard protective sheets 40, 41, a procedure of emplacing the hard protective sheet followed by pouring the vinyl can be included in an automatic operation process of the LED lamp bank, and can be controlled by an automatic procedure, without affecting its original manufacturing cost or increasing time of labor. The installation of the hard protective sheets 40, 41 can prevent from a dragging to compressing the LED lamp and the related element due to natural contraction in cold temperature and swelling in hot temperature under a long time of usage of the vinyl, thereby truly reducing a failure rate.
The hard protective design of the LED lamp bank of the present invention can be also arranged according to structural requirement for a shining control of the LED lamp. As shown in FIG. 16 and FIG. 17, the LED lamp 13 and a related electronic element 31 can be installed on a hard circuit board 30 and then are welded on the substrate 16, so as to enlarge a free bending space Z of each LED lamp 13, without decreasing a free bending space W (as shown in FIG. 2) of the prior art wherein a resistor 14 is located between the LED lamps 13; thereby allowing the hard circuit board 30 to be provided with a protection effect of the hard protective sheet. As the larger the free bending space is, the more convenience the arc and bending degree of the LED lamp bank are; thus the LED lamp bank can more develop a variation of original convenience in arranging a pattern.
The hard circuit board 30 can wrap and beautify a plastic according to requirement, thereby achieving another effect of beauty and having an effect of enhancing hardness.
The hard protective sheet design of the LED lamp bank of the present invention can also thicken a part of the soft vinyl 17 where the LED lamp is located; that is, a thicken part 171 is formed above the position of the LED lamp 13 of the LED lamp bank, as shown in FIG. 18 and FIG. 19, or, a thicken part 172 is formed integrally on a part of the lower soft substrate 16 where the LED lamp 13 is located as shown in FIG. 20 and FIG. 21.
Accordingly, the LED lamp bank of the present invention really improves the shortcomings in using the conventional LED lamp bank, and provides an easy and convenient implementation method, thereby definitely providing an invention which saves time and labor, and is economic and practical.
It is of course to be understood that the embodiments described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
