Description

Light-emitting components and light guides

The present invention relates to a light-emitting component and a light-guiding component, in particular to a light-guiding component comprising a light-guiding column and a light-emitting component comprising the light-guiding component.

In recent years, in addition to the performance, the visual effect presented by the notebook computer has gradually received more attention. Therefore, some manufacturers will install light-emitting elements and light guide plates in the casing of the notebook computer, so that the light emitted by the light-emitting elements can be guided to the edge of the casing with the help of the light guide plate and emitted to the outside. In this way, when the notebook computer is in operation, for example, the light-emitting element can be controlled to present different visual effects according to different operating states of the notebook computer.

However, since the light emitted by the light-emitting element is only guided by the plate-shaped light guide plate, the visual effect presented by the notebook computer is limited to planar or two-dimensional light changes or light and shadow changes. As a result, the visual effect presented by the notebook computer will be too monotonous without rich changes.

The present invention provides a light-emitting component and a light-guiding element to present four-dimensional and varied visual effects through the light-guiding column.

A light-emitting component disclosed in an embodiment of the present invention includes a circuit board, a plurality of light-emitting elements, a first light guide and at least a second light guide. The light emitting element is electrically connected to the circuit board and arranged on one side of the circuit board. The first light guide is disposed on the circuit board, and the light emitting element is interposed between the circuit board and at least part of the first light guide. At least one second light guide includes an assembly plate and a plurality of light guide columns. The assembly board is arranged on the side of the first light guide away from the circuit board. The light guide column protrudes from the side of the assembly board away from the first light guide member. The light emitting element is used for emitting light toward the light guide column.

The light guide disclosed in another embodiment of the present invention includes an assembly plate and a plurality of light guide columns. The light guide column protrudes from one side of the assembly board.

According to the light-emitting component and the light-guiding element disclosed in the above-mentioned embodiments, since the light-guiding column protrudes from one side of the assembly board, the light emitted from the light-emitting element can present four-dimensional light changes or light-shadow changes after being guided by the light-guiding column And make the lighting effect more abundant.

The detailed features and advantages of the embodiments of the present invention are described in detail below in the implementation manner, the content is enough for anyone with ordinary knowledge in the field to understand the technical content of the embodiments of the present invention and implement them accordingly, and according to the disclosure of this specification Anyone with ordinary knowledge in the art can easily understand the purpose and advantages of the present invention.

In each of the side light guides 420 , the assembly plate 421 is disposed on the side of the first light guide 300 away from the circuit board 100 , for example, by buckling. The light guide column 422 protrudes from a side of the assembly board 421 away from the first light guide member 300 . The two first buckle structures 423 are located on the same side of the assembly board 421 and separated from each other. The first buckle structure 423 and the light guide post 422 are located on different sides of the assembly board 421 .

In this embodiment, the intermediate light guide 440 includes an assembly plate 441 , a plurality of light guide columns 442 , two second buckle structures 443 and two third buckle structures 444 . The assembling board 441 is disposed on the side of the first light guide 300 away from the circuit board 100 by, for example, buckling. The light guide column 442 protrudes from a side of the assembly board 441 away from the first light guide member 300 . The two second locking structures 443 are located on the same side of the assembly board 441 and separated from each other. The two third buckle structures 444 are located on the same side of the assembly board 441 and separated from each other. The two second buckle structures 443 and the two third buckle structures 444 are respectively located on opposite sides of the assembly plate 441 . The second buckle structure 443 , the second third buckle structure 444 and the light guide post 442 are located on different sides of the assembly board 441 .

In this embodiment, opposite sides of the assembling plate 441 of the middle light guide 440 are respectively detachably disposed on the assembling plates 421 of the two side light guides 420 . In detail, the two first buckle structures 423 of one side light guide 420 are engaged with the two second buckle structures 443 of the middle light guide 440 respectively, and the two first buckle structures of the other side light guide 420 The buckle structures 423 are respectively engaged with the second and third buckle structures 444 of the middle light guide 440 . In addition, in this embodiment, the first buckle structure 423 and the two second buckle structures 443 of one of the side light guides 420 are respectively matching hooks and slots, and the other side light guide 420 The two first buckle structures 423 and the two third buckle structures 444 are matching grooves and hooks respectively. In addition, the side of the assembling plate 421 of the two-side light guide 420 away from the middle light guide 440 is used for fixing to the casing.

It should be noted that the second light guide 400 (that is, the side light guide 420 and the middle light guide 440 ) can also be partially attached with a black light-shielding sheet made of plastic to provide local protection like the first light guide 300 . Shading effect. Other implementations of the partial light-shielding of the second light guide 400 and the achieved effects are similar to those of the first light guide 300 , so details will not be repeated here.

The present invention is not limited by the quantity of the second light guide 400 . In other embodiments, the light-emitting component may also include only one second light guide, and the opposite sides of the second light guide are used to be fixed to the casing.

In this embodiment, the middle light guide 440 is detachably disposed on the two side light guides 420 . Therefore, in this embodiment, at least one second light guide 400 is provided through modularization. In this way, the middle light guide 440 and the side light guide 420 can be manufactured sequentially through the mold by injection molding, instead of manufacturing a long light guide at one time, which avoids the light guide due to The longer the length, the greater the risk of deformation during injection molding. In addition, in other embodiments, the number of intermediate light guides can also be increased according to actual needs. In such an embodiment, the intermediate light guides can be manufactured through the same mold to reduce the manufacturing cost of the light emitting assembly.
