The following examples further illustrate the aspects of the utility model in detail, but are not intended to limit the scope of the utility model in any way.
Referring to fig. 1 and 2, fig. 1 is an exploded perspective view of a light emitting device according to an embodiment of the utility model. Fig. 2 is a partial enlarged view of another exploded perspective view of the light emitting assembly of fig. 1.
In the present embodiment, the light emitting device 10 is disposed in a housing of an electronic device (not shown), for example. In the present embodiment, the light emitting assembly 10 includes a circuit board 100, a plurality of light emitting elements 200, a first light guide 300 and at least one second light guide 400.
The light emitting element 200 is electrically connected to the circuit board 100 and disposed on one side of the circuit board 100. The first light guide 300 is fixed to the circuit board 100, for example, by heat fusion. The light emitting element 200 is interposed between the circuit board 100 and at least a portion of the first light guide 300. In addition, in the present embodiment, the first light guide 300 provides a local shading effect to make the light emitted from the light emitting element 200 more stereoscopic. For example, in the present embodiment, a black light shielding sheet made of plastic is locally attached to the first light guide 300 to provide a local light shielding effect, but the utility model is not limited thereto. In other embodiments, black ink may be added to the first light guide member by printing, transfer printing, or painting, for example, so that the first light guide member provides a local shading effect.
In addition, the light emitted by the light emitting element 200 becomes more uniform after being guided by the first light guiding element 300, and the first light guiding element 300 reduces the intense light effect of the single light emitting element 200, so that the light guided by the first light guiding element 300 is more natural.
In this embodiment, the at least one second light guide 400 includes two side light guides 420 and a middle light guide 440. The middle light guide 440 is interposed between the two side light guides 420.
In the present embodiment, the two side light guides 420 each include a set of plates 421, a plurality of light guide posts 422, and two first fastening structures 423. In each side light guide 420, the assembly plate 421 is disposed on a side of the first light guide 300 away from the circuit board 100, for example, by a snap-fit manner. The light guide posts 422 protrude from the side of the assembly plate 421 away from the first light guide 300. The two first fastening structures 423 are located on the same side of the assembly plate 421 and separated from each other. The first fastening structure 423 and the light guiding post 422 are located at different sides of the assembly plate 421.
In the present embodiment, the middle light guide 440 includes a set of plates 441, a plurality of light guide posts 442, two second fastening structures 443, and two third fastening structures 444. The assembly plate 441 is disposed on a side of the first light guide 300 away from the circuit board 100, for example, by means of a buckle. The light guide column 442 protrudes from a side of the assembly plate 441 away from the first light guide 300. The two second fastening structures 443 are located on the same side of the assembly plate 441 and are separated from each other. The two third snap structures 444 are located on the same side of the assembly plate 441 and are separated from each other. The two second fastening structures 443 and the two third fastening structures 444 are respectively located at two opposite sides of the assembly plate 441. The two second fastening structures 443, the two third fastening structures 444 and the light guide post 442 are located at different sides of the assembly plate 441.
In the present embodiment, opposite sides of the assembly plate 441 of the middle light guide 440 are detachably disposed on the assembly plates 421 of the two side light guides 420, respectively. In detail, the two first fastening structures 423 of one side light guide 420 are respectively fastened to the two second fastening structures 443 of the middle light guide 440, and the two first fastening structures 423 of the other side light guide 420 are respectively fastened to the two third fastening structures 444 of the middle light guide 440. In addition, in the present embodiment, the first fastening structure 423 and the second fastening structure 443 of one side light guide 420 are respectively a matched fastening groove and a fastening groove, and the second fastening structure 423 and the third fastening structure 444 of the other side light guide 420 are respectively a matched fastening groove and a fastening groove. In addition, the assembling plate 421 of the two side light guides 420 is fixed to the housing on a side far away from the middle light guide 440.
It should be noted that, the black light shielding sheet made of plastic may also be locally attached to the second light guide 400 (i.e. the side light guide 420 and the middle light guide 440) to provide a local light shielding effect like the first light guide 300. Other embodiments of the second light guide 400 for partially shielding light and the achieved effects are similar to those of the first light guide 300, and thus will not be described again.
The number of the second light guide 400 is not limited in the present utility model. In other embodiments, the light emitting device may also include only one second light guide member, and two opposite sides of the second light guide member are fixed to the housing.
In this embodiment, the middle light guide 440 is detachably disposed on the two side light guides 420. Therefore, the present embodiment provides at least one second light guide 400 in a modularized manner. In this way, the middle light guide 440 and the side light guide 420 can be manufactured by injection molding through the mold sequentially, without manufacturing the light guide with a longer length at one time, which avoids the risk of the light guide being deformed to a large extent during injection molding due to the longer length. In addition, in other embodiments, the number of the intermediate light guide members may be increased according to actual requirements. In such embodiments, the intermediate light guides may be manufactured by the same mold to reduce the manufacturing cost of the light emitting assembly.
In addition, in the present embodiment, for example, light-equalizing particles are added to the middle light guide 440 and the side light guide 420 to make the light emitted from the light-emitting element 200 more uniformly transmitted to the outside.
Referring to fig. 2 and 3, fig. 3 is a partial enlarged view of a front view of the light emitting device in fig. 1. The light guide posts 422 of the side light guide 420 and the light guide posts 442 of the middle light guide 440 are arranged in an array, for example. In addition, in the present embodiment, the number of the light emitting elements 200 is equal to the sum of the number of the light guide posts 422 of the side light guide member 420 and the number of the light guide posts 442 of the middle light guide member 440, and the light emitting elements 200 are respectively configured to emit light toward the light guide posts 422 and 442. In this way, for example, by adjusting the colors of the light emitting elements 200, the light guide posts 422 and 442 can emit various visual effects. It should be noted that, in other embodiments, the number of light emitting elements may be greater or less than the sum of the number of light guiding columns of the side light guiding members and the number of light guiding columns of the middle light guiding member.
Referring to fig. 2 and 4, fig. 4 is a side view of the light emitting device in fig. 1. In the present embodiment, the protruding lengths L of the light guide posts 422 relative to the assembly plate 421 are different from each other, for example, to match the shape of the housing in which the light emitting device 10 is disposed. It should be noted that, in other embodiments, the protruding lengths of the light guide posts relative to the assembly plate may be the same.
According to the light emitting assembly and the light guide member disclosed in the embodiments, the light guide column protrudes from one side of the assembly plate, so that light emitted from the light emitting element can exhibit four-dimensional light change or light shadow change after being guided by the light guide column, and the light effect is richer.
Although the present utility model has been described with reference to the above embodiments, it should be understood that the utility model is not limited thereto, but rather may be modified or altered somewhat by persons skilled in the art without departing from the spirit and scope of the utility model.
