technical field

The utility model relates to a light emitting module, in particular to a light emitting module with a flexible cable and a plurality of carrier boards.

Background technique

At present, various light-emitting module products have been widely used in daily life, especially light-emitting modules with light-emitting diodes. Whether it is on clothes, bracelets or some accessories, LEDs can be installed to achieve the purpose of decoration or warning.

In the prior art, most light-emitting modules with light-emitting diodes are mounted on printed circuit boards (Printed Circuit Board, PCB) or flexible printed circuit boards (Flexible Printed Circuit, FPC). If the light-emitting diodes are installed on the printed circuit board, it will be limited by the volume of the printed circuit board and cannot make too many changes.

On the other hand, as shown in FIG. 1A , FIG. 1A is a schematic diagram of a first embodiment of a light emitting module in the prior art. The prior art light emitting module 90a is a module mounted on a flexible printed circuit board 91a. The flexible printed circuit board 91a has a driving module 92a, a plurality of LEDs 93a and a plurality of electrical wires 94a. The driving module 92a utilizes a plurality of electrical wires 94a to respectively control a plurality of LEDs 93a. If the driving module 92a needs to individually control the light emitting diodes 93a, the wiring method of the electric wire 94a must be specially designed. In this way, the cost of manufacturing will be increased. On the other hand, although the flexible printed circuit board 91a can be bent, the bending range and number of times are limited, and there are certain limitations in application.

Another light emitting module embodiment is also disclosed in the prior art. Please refer to FIG. 1B for a schematic diagram of a second embodiment of a light emitting module in the prior art. The light emitting module 90b is a module mounted on a flexible flat cable (FFC) 91b. The flexible flat cable 91b has a driving module 92b, a plurality of LEDs 93b and a plurality of electrical wires 94b. The driving module 92b utilizes a plurality of electrical wires 94b to respectively control a plurality of LEDs 93b. Compared with the flexible printed circuit board 91a, the flexible flat cable 91b can have a larger bending range and times. But on the other hand, if the driving module 92b wants to individually control the light emitting diodes 93b, different light emitting diodes 93b must be connected to different electric wires 94b. In this way, different light emitting diodes 93b are located at different heights, and the light emitting module 90b looks less beautiful.

Therefore, it is necessary to develop a new type of light-emitting module to solve the problems in the prior art.

Detailed ways

In order to make the technical content of the present utility model easier to understand, preferred specific embodiments are described as follows.

Please refer to FIG. 2 for a schematic diagram of the light-emitting module of the present invention.

The light emitting module 10 of the present invention includes a flexible cable 20 and a plurality of carrier boards 30 . In this embodiment, the flexible cable 20 is a flexible flat cable (Flexible Flat Cable, FFC), but the present invention is not limited thereto. The flexible cable 20 is made of an insulating material 21 and a plurality of electrical wires 22 . In this embodiment, the plurality of electrical wires 22 are composed of a first electrical wire 22a, a second electrical wire 22b, a third electrical wire 22c and a fourth electrical wire 22d, but the present invention is not limited thereto. The electrical leads 22 are made of very thin tinned flat copper wire. The insulating material 21 is used to cover a plurality of electrical conductors 22 , and a part of the flexible cable 20 is stripped off the insulating material 21 by stripping the electrical conductors 22 to form a plurality of electrical connections 23 . The wire stripping method can utilize a blade to peel off the insulating material 21, but the utility model is not limited to this method.

The plurality of carrier boards 30 are connected to the plurality of electrical connections 23 by welding to electrically connect the plurality of electrical wires 22 . In this embodiment, the soldering method is to use a low-temperature solder paste for soldering, so as to avoid damage to the flexible cable 20 due to overheating during the soldering process. And due to the characteristics of the flexible cable 20 , when the flexible cable 20 is bent, electric power can still be transmitted between the multiple carriers 30 . In FIG. 2 , the plurality of carrier boards 30 include a first carrier board 30 a , a second carrier board 30 b and a third carrier board 30 c , but the present invention is not limited thereto. It should be noted that the distance between different carrier boards 30 , for example, the distance between the first carrier board 30 a and the second carrier board 30 b can be adjusted as required. As long as the carrier board 30 can be soldered to a plurality of electrical connections 23 , the present invention is not limited to the spacing shown in FIG. 2 . The plurality of carrier boards 30 are used for setting the driving module 31 and the light emitting diodes 32 . In this embodiment, the first carrier board 30a is used for disposing the driving module 31 , and the other second carrier board 30b and the third carrier board 30c are used for disposing the first LED 32a and the second LED 32b. The driving module 31 is used to control the first light emitting diode 32a and the second light emitting diode 32b so that they can be turned on or off. The driving module 31 can also control the sequence in which each of the first light emitting diodes 32 a and the second light emitting diodes 32 b emit light.

On the other hand, the surface of the carrier board 30 and the multiple electrical connections 23 is covered with insulating glue or a protective film (not shown), so as to increase the bending of the joints between the carrier board 30 and the plurality of electrical connections 23 tolerance. The protective film is made of polypropylene (PP), but the present invention is not limited to this material.

Next, please refer to FIG. 3A- FIG. 3B together for the schematic diagrams of the electrical connection of the light-emitting diodes on the carrier board of the present invention. Light emitting diodes 32 capable of emitting different colors may also be provided on the light emitting module 10 , and the present invention is not limited to the light emitting diodes 32 of a single color. When the first light emitting diodes 32a and the second light emitting diodes 32b of different colors are provided, the circuit layouts on the second carrier board 30b and the third carrier board 30c will also change. In this embodiment, the flexible cable 20 is composed of a first electrical wire 22a, a second electrical wire 22b, a third electrical wire 22c and a fourth electrical wire 22d. The first light-emitting diode 32a and the second light-emitting diode 32b are electrically connected to different electric wires 22 through a resistor R, so the driving module 31 issues control commands through different electric wires 22 to control different first light-emitting diodes 32a and second light-emitting diodes. The diodes 32b emit lights of different colors at the same time or at different times.

For example, in FIG. 3A , the driving module 31 is electrically connected to the first light emitting diode 32 a through the first electrical wire 22 a and the second electrical wire 22 b to control the first light emitting diode 32 a. In FIG. 3B , the driving module 31 is electrically connected to the second light emitting diode 32 b through the first electrical wire 22 a and the third electrical wire 22 c to control the second light emitting diode 32 b. Therefore, the driving module 31 can simultaneously control the first light emitting diode 32 a and the second light emitting diode 32 b through different electric wires 22 . And because the second carrier board 30b and the third carrier board 30c are at the same height, when different first LEDs 32a and second LEDs 32b emit light, their light positions will remain in a straight line. This makes the appearance of the light emitting module 10 look more beautiful. It should be noted that since different first light emitting diodes 32 a and second light emitting diodes 32 b require different powers, it is necessary to electrically connect resistors R with different resistance values to adjust their receiving power.

The light-emitting module 10 of the present invention can be used for decorations, clothes, warning devices or bracelets, etc., which need to emit light for decoration or warning, but the present invention is not limited to the above-mentioned embodiments.

To sum up, the present utility model has characteristics different from those of the prior art regardless of its purpose, means and efficacy. However, it should be noted that the above-mentioned embodiments are examples only for convenience of description, and the scope of protection claimed by the utility model should be determined by the scope defined in the claims, rather than limited to the above-mentioned embodiments.
