Multi-faceted light-emitting diode lamps

The invention relates to luminaires, and more particularly to a multi-faceted illuminating diode luminaire.

Light-Emitting Diode (LED) not only has the advantages of small size, long life, low power consumption and high luminous efficiency, but also emits light-emitting diodes that people are used to illuminate in recent years. It has been successfully mass-produced, and therefore, light-emitting diodes have been more and more widely used in lighting fixtures. Although the LEDs can make the lighting performance of the lamps better, the lamps are not only used to facilitate the lighting of modern people, but also to decorate the environment, even the artworks. Therefore, a luminaire that has only good luminescence properties but is too simple in shape or illuminating effect cannot meet the actual needs.

Most of the lamps used in the market for light-emitting diodes are flat-type designs, that is, a plurality of light-emitting diodes are disposed on a circuit board, and power is supplied by a power supply to make the light-emitting diodes Illuminate to produce an illumination effect. However, the above-mentioned planar design of the LED lamp not only emits light in a single direction, but also has limited variability in the shape of the lamp.

In other words, the conventional LED lamp has its shortcomings and needs to be improved.

In view of the above-mentioned deficiencies, the main object of the present invention is to provide a multi-faceted light-emitting diode lamp, which not only has good luminous performance, but also has a beautiful three-dimensional shape and can emit light in multiple directions.

The light emitting elements are disposed on at least two of the circuit boards, and the light emitting elements are electrically connected to each other. The battery is disposed on one of the circuit boards and electrically connected to the light emitting elements. Thereby, the exterior of the lamp has a polyhedral shape, which can add aesthetics, and the light-emitting elements are disposed on the circuit board of at least two different faces, and at least two different faces of the polyhedron can be The luminaire emits light in at least two different directions. In addition, the light-emitting elements may be light-emitting diodes to make the light-emitting performance of the light fixture more favorable.

The perforations 36 are located in the same conductive unit 34.

For convenience of description, the present embodiment divides the foregoing six circuit boards 20 into one power supply circuit board 22 and five light-emitting circuit boards 24. Referring to the third figure, the multi-face-emitting diode lamp 10 further includes a battery 16 for providing the required direct current of the light-emitting diodes 14. The circuit board 22 is provided with a circuit 222 and a plurality of screw holes 226. The circuit 222 has two contacts 224, and the two contacts 224 are located in two of the screw holes 226. The battery 16 and the LED 14 are electrically connected to the circuit 222. In this embodiment, the battery 16 is fixed to the power circuit board 22. . Each of the light-emitting circuit boards 24 has at least one circuit 242 and a plurality of screw holes 246. Each of the circuit blocks 242 has two contacts 244. The two contacts 244 are respectively located in the screw holes 246 of the light-emitting circuit board 24. Within both.

The battery 16 and each of the light-emitting diodes 14 are electrically connected to the circuit 242. The two adjacent circuit boards (ie, the power circuit board 22 and the light-emitting circuit board 24) are connected and fixed by the connecting members 30. The contacts 224 and 244 of the circuits 222 and 242 are electrically connected to each other by the two conductive units 34 of the connectors 30. Wherein, the light emitting diodes 14 are The positions on the boards 22, 24 are merely illustrative and are therefore not limited to those depicted in the figures.

As shown in the fourth figure, the fourth figure only shows a partial cross-sectional view of the power circuit board 22, the light-emitting circuit board 24, and the connector 30 in the third figure. The bolts 18 of the connecting member 30 are respectively locked to the power circuit board 22 and the light emitting circuit board 24, so that the circuit 222 of the power circuit board 22 and the circuit 242 of the light emitting circuit board 24 are supported by the connecting member 30. The two conductive units 34 are electrically connected to each other. Thus, when the power circuit board 22 and the circuits 222 and 224 of the light-emitting circuit boards 24 are combined by the connecting members 30, the third drawing can be realized.

It should be noted that, as shown in the third figure, the partial connectors 30 are only used to fix the adjacent two circuit boards 22, 24 without the circuits 222, 242 connecting the circuit boards 22, 24, so the connections are not connected. The connecting members 30 of the circuits 222, 242 of the circuit boards 22, 24 may be made of a structure having a soft shop board or a generally insulating material.

With the foregoing structure, the lamp 10 not only has a three-sided shape of a hexahedron, but also has a light-emitting diode 14 on each side, and the user can install the lamp 10 in a suspended manner when the battery 16 is mounted. When the illuminating electric energy required for the light-emitting diodes 14 is supplied, the luminaire 10 can be divided into six parts Don't emit light in six different directions.

In the foregoing luminaire 10, since the circuit boards 20 can be replaced with each other in structure, only some circuits of the circuit board 20 are different. Therefore, if some circuit boards 20 are damaged, the series circuit is broken. In this case, the positions of the circuit boards 20 can be rearranged such that the damaged circuit board 20 is excluded from the series circuit and the circuits of the other intact circuit boards are connected to form a circuit comprising a series circuit with the battery 16. The luminaire 10 can still emit light in different directions from some of its faces.

In the lamp 10 described above, the components for connecting the adjacent two circuit boards 20 are not limited to the connector 30 as described above, and may be replaced by another connector 40 structure as shown in FIG. Connector 30. The connector 40 has a pair of two conductive units 42, 44, each of which is made of a metal or other conductive material to form a hinge-like member and has two through holes 46 therethrough. In this way, as long as the conductive units 42 and 44 of the connecting member 40 are pivoted to each other in a perpendicular shape, they can be connected to the adjacent two circuit boards 20 according to the mounting manner of the connecting member 30, and then assembled. The hexahedral lamp holder 12 can connect the battery 16 and the light-emitting diodes 14 to each other to form a closed loop. In addition, the connection manner of each of the connecting members 30 or 40 and the circuit board 20 is not limited to the manner in which the bolts 18 are disposed in the through holes 36 or 46, and the connecting members 30 or 40 and the circuit boards 22 and 24 may be utilized.

The power circuit board 22, the light-emitting circuit board 24, and the decorative circuit board 26 are connected by the connectors 30. Of course, the connectors 30 can also be replaced by connectors 40. Therefore, when the circuit boards 22, 24, and 26 are assembled into the lamp holder by the connector 30 or 40, only the power circuit board 22 and the light-emitting circuit board 24 are electrically connected into a series circuit. In this way, the luminaire emits light in five different directions only from the five faces of the light-emitting diode 14 . The non-light emitting surface formed by the decorative circuit board 26 can be used by the user to install a suspension rope (not shown) so that the light fixture can be suspended at a desired place; or the non-light emitting surface can also be The user can directly place the lamp on a table top or other flat place; in addition, the decorative circuit board 26 can also be provided with a decorative pattern to have a decorative effect.
