1. Field of the Invention
The present invention relates to a cover used by an electronic device, in particular, to a cover that has a logo and the logo has three-dimensional appearance.
2. Description of the Related Art
Generally, an electronic device such as a notebook computer has a cover in which a product logo is provided to thereby emphasize the brand and for the purpose of increasing rate of market exposure.
Conventionally, a 2-D logo is used, as it can be easily made and easily fixed to the cover. However, the practice of using the 2-D logo has become too customary for the public and therefore has little effect to engrave itself into our memory.
While the prior art teaches a 3-D logo, the 3-D logo is made by involving recesses-cutting process, which is regarded as not favoring. Also, the logo itself is easily damaged by abrasion.
U.S. Pat. No. 6,494,593 teaches an alternative method to promote its product logo 800, in which the logo 800 is shined by a light emitting part 21. Notwithstanding the logo 800 becomes more promotive in comparison to a 2-D logo, the logo 800 still can not have a 3-D appearance. Furthermore, it is noted that the invention includes a plurality of holes 700 that allows for light emitted from the light emitting part 21 to shine the logo 800, these holes 700 are not favoring, because these holes 700 incur an extra process and cost. Additionally, the holes 700 can induce dust to get into the case 200, thus resulting electrostatic problem to electronics.
The present invention is, therefore, intended to obviate or at least alleviate the problems encountered in the prior art.
According to the present invention there is provided, a cover of an electronic device has a body installed inside and is penetrable by light yielded from an illumination device. Preferably, the illumination device is mounted in the cover.
In one embodiment, the body has an inner surface incorporating a material impenetrable by light as a light-blocking region and the remaining of the inner surface defined as a light-passing region. The body further has an outer surface incorporating a material impenetrable by light as a light-blocking region and the remaining of the outer surface as a light passing region. The light-blocking region of the outer surface corresponds to the light-passing region of the inner surface in shape, but in a size that is smaller, so that when light passes through the body, light can pass through a gap defined between the contour of the light-blocking region on the outer surface and the light-passing region on the inner surface, and whereby gives an effect that the shape of the light-blocking region on the outer surface of the body looks three-dimensional.
In another embodiment, the light blocking regions of the body are coarse surfaces fabricated from the body so that the regions become translucent.
It is a primary object of the present invention that the light-blocking region on the outer surface of the body and the light-passing region on the inner surface of the body are representative of a product logo.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The present invention will be described with reference to the accompanying drawings which assist in illustrating the pertinent features thereof, in which:
