The subject matter herein generally relates to housings of electronic devices, especially to a housing of an electronic device with a formed light-emitting portion.
A housing of an electronic device defines a plurality of light transmission holes, arranged in a predetermined shape. Light from a light source in the electronic device emits out of the housing through the light transmission holes, and a light-emitting portion is formed from the housing.
Implementations of the present technology will now be described, by way of example only, with reference to the attached figures.
It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure.
Several definitions that apply throughout this disclosure will now be presented.
The term “coupled” is defined as connected, whether directly or indirectly through intervening components, and is not necessarily limited to physical connections. The connection can be such that the objects are permanently connected or releasably connected. The term “outside” refers to a region that is beyond the outermost confines of a physical object. The term “inside” indicates that at least a portion of a region is partially contained within a boundary formed by the object. The term “substantially” is defined to be essentially conforming to the particular dimension, shape or other word that substantially modifies, such that the component need not be exact. For example, substantially cylindrical means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
The base plate 110 can be a substantially flat plate and made of transparent materials, such as glass, sapphire, transparent ceramics. The base plate 110 can include an inside surface 111 and an outside surface 112.
The frame 120 can be made of plastic materials, and include a first receiving portion 121 configured to receive the base plate 110 and a second receiving portion 122 configured to receive the light guide film 130. An edge of the first receiving portion 121 can include a circular lip 1211 attached to an edge of the base plate 110. The lip 1211 can prevent the base plate 110 from being damaged. The second receiving portion 122 can be defined in a predetermined portion of the first receiving portion 121. The first receiving portion 121 can surround the second receiving portion 122. The second receiving portion 122 can define a hollow portion 1221 and include a support portion 1222 arranged at an edge of the hollow portion 1221. The hollow portion 1221 can be defined in a predetermined portion of the first receiving portion 121. A shape of the hollow portion 1221 can be substantially same as a shape of the light guide film 130, and can be configured to receive the light guide film 130. The support portion 1222 can be configured to support the light guide film 130.
The light guide film 130 can include a light input portion 131, a light guide portion 132 and a light output portion 133. The light input portion 131 can be coupled with the light guide portion 132 at a predetermined angle. The light input portion 131 can be close to the light source 140 to improve the light-transmitting efficiency of the light guide film 130. The light guide portion 132 can be coupled with the light output portion 133, and be configured for transmitting light from the light input portion 131 to the light output portion 133. The light output portion 133 can include a scattering microstructure 1331, and light can emit out of the light guide film 130 through the scattering microstructure 1331.
The light source 140 can be closely coupled to the light guide film 130 and configured to emit light for the housing 100. In the illustrate embodiment, the light source 140 can include a plurality of light-emitting diodes (LEDs). The plurality of LEDs can emit different color light.
In another embodiment, the frame 120 can further include a plurality of latches to allow coupling with other components of the housing 100.
The light guide film 230 can include a light guide portion 231 and a light output portion 232 coupled with the light guide portion 231. The light guide portion 231 and the light output portion 232 can be on the same level. The light source 240 can be closely coupled to the light guide film 230. A surface of the light guide film 230 away from the base plate 210 can include a reflective film 233. A portion of the light output portion 232 near the light transmission holes 213 can define a first scattering microstructure 2321, and the first scattering microstructure 2321 can be attached to the plurality of the light transmission holes 213. Light from the light guide film 230 can be transmitted to the light transmission holes 213 through the first scattering microstructure 2321, and can pass through the base plate 210 to the outside of the housing 200. A portion of the light guide portion 231 near the light source 240 can define a second scattering microstructure 2311. The second scattering microstructure 2311 can be optically coupled to the light source 240, and light from the light source 240 can enter the light guide film 230 through the second scattering microstructure 2311.
A shade layer 311 can be coated on the total areas of the inside surface of the base plate 310. A plurality of light transmission holes 312 arranged in a predetermined shape can be defined on a predetermined portion of the shade layer 311.
The second scattering microstructure 3311 can be optically coupled to the light source 340, and light from the light source 340 can enter the light guide film 330 through the second scattering microstructure 3311. The first scattering microstructure 3321 can be attached to the plurality of the light transmission holes 312. Light from the light guide film 330 can be transmitted to the light transmission holes 312 through the first scattering microstructure 3321, and can pass through the base plate 310 to the outside of the housing 300.
The embodiments shown and described above are only examples. Many details are often found in the art such as the other features of housing of electronic device. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the details, including in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above may be modified within the scope of the claims.
