Description
Technical field
The present invention relates to a kind of identification pattern light-emitting device, particularly relating to a kind of being positioned at does not need additionally to provide light source to make the luminous identification pattern light-emitting device of identification pattern on the display casing.
Background technology
Because it is scientific and technological at a tremendous pace now, electronic correlation industry technology advances day by day, make electronic product stride forward towards light, thin, short, little target always, therefore how electronic product being brought into play the ultimate attainment and aesthetic in appearance of its effect is that the popular institute of mass society can accept, how to be propagated to improve market share, electronic correlation industry personage is badly in need of breaking through the target of development especially.
No matter desktop PC and mobile computer all use a display that institute input data are manifested, therefore make manufacturer in order to propagate, the identification pattern (Logo) that nearly all can be sticked in display casing or appropriate position is discerned.
Identification pattern not only provides its its effect of also being particular about aesthetic in appearance.For example, when computing machine is in the position of insufficient light, often because operating personnel can't judge computer location, and careless collision, so identification pattern promptly provides the position indicator pointer an of the best.But, when being manifested for identification pattern knows in the position of insufficient light, must additionally provide a light source just can finish, this disagrees towards light, thin, short, little target with electronic product again, and this problem is the very urgent solution that will seek of the manufacturer of electronic product in fact.
Summary of the invention
A purpose of the present invention is to provide a kind of identification pattern light-emitting device, can not need additionally to provide light source to make the luminous effect of identification pattern to reach by be used in the light source of display with the guiding of identification pattern light-emitting device.
Another object of the present invention is to provide a kind of identification pattern light-emitting device, this identification pattern light-emitting device can provide the user clearly to observe identification pattern when insufficient light, to reach the effect that display appearance is beautified and propagated.
For reaching above-mentioned purpose, a kind of identification pattern light-emitting device of the present invention, it is used to comprise a display of a light source and a light guide plate, the identification pattern light-emitting device includes: a shell, a lid and a light lead body.
Shell is provided with a groove, can provide to be embedded an identification pattern, and groove has one first opening.Shell has an accommodation space, and lid is arranged in the accommodation space, and with shell at a distance of a suitable spacing.Lid has a perforation, and perforation is corresponding with first opening.The light lead body passes the perforation and first perforate.The light lead body has one first end face and one second end face, and first end face links to each other with first perforate, and second end face contacts with light guide plate.Light lead body and light guide plate can be with the ray guidance of light source to identification patterns, make identification pattern luminous and do not need extra light source.

Embodiment
Identification pattern light-emitting device of the present invention can be directed to this identification pattern by a light lead body and a light guide plate with the light from the display light source, makes this identification pattern luminous and do not need extra light source.
See also Figure 1 and Figure 2, the three-dimensional decomposition texture synoptic diagram of the preferred embodiment that it cooperates with display for identification pattern light-emitting device of the present invention.It applies to identification pattern light-emitting device 2 on the display 1, and display 1 can provide the operator to observe the information of its output.Display 1 comprises an at least one light source 11 and a light guide plate 12, in preferred embodiment of the present invention, this light source 11 its to be that two sides are corresponding respectively have one, but also singly have only certainly one or more, more than this light source 11 quantity its for prior art so no longer add to give unnecessary details at this.The light of light source 11 evenly distributes light by light guide plate 12, observes so that the operator to be provided.
Identification pattern light-emitting device 2 comprises a shell 21, a lid 22 and a light lead body 23.In embodiments of the present invention, shell 21 1 grooves 212 can provide to be embedded an identification pattern 24.Groove 212 also has one first opening 213.Shell 21 is for asking light, can be with plastic injection-moulded one-body molded making, and shell 21 is also made with the moulding of aluminum alloy die cast certainly.Shell 21 has an accommodation space 211, and lid 22 its be arranged in the accommodation space 211, and with shell 21 at a distance of a suitable spacing.Lid 22 also has a perforation 221, and it is 221 corresponding with first opening 213 to bore a hole.Lid 22 is made with the moulding of aluminum alloy die cast usually.
See also Fig. 3 and shown in Figure 4, it is the side-looking cross-sectional view that identification pattern light-emitting device of the present invention preferred embodiment and A partly amplify.Light lead body 23 passes perforation 221 and first opening 213 and is provided with.Light lead body 23 passes through for the ease of the light of light source, so can use the leaded light material of bright olefin(e) acid material, makes forming with the integrated through injection molding molding mode.Light lead body 23 is effectively to derive enough light, can be one to have the column structure of various cross-sectional areas.In embodiments of the present invention, its end face is round-shaped right cylinder, also can be square column or other polygon cylinder certainly.The variation of shape like that its by be familiar with this type of operator energy changed enforcement according to above-mentioned exposure, will not lose main idea of the present invention place, do not break away from the spirit and scope of the present invention, so do not add to give unnecessary details at this yet.
Two ends of light lead body 23 have one first end face 231 respectively and one second end face, 232, the first end faces 231 link to each other with first opening 213 of outer casing groove.Light guide plate 12 also has one second opening 121, makes second opening 121 relative with second end face 232 of light lead body.Light lead body 23 also has one the 3rd end face 233, be located between first end face 231 and second end face 232, and the 3rd end face 233 places perforation 221.In embodiments of the present invention, the sectional area of first end face 231 is less than the sectional area of the 3rd end face 233, and the sectional area of second end face 232 is also less than the sectional area of the 3rd end face 233.After the light of light source 11 is evenly distributed on the light guide plate 12, provide light to the second end face 232 by opening 121.Because of the sectional area of second end face 232 its less than the 3rd end face 233, therefore light spread.And the sectional area of the 3rd end face 233 makes light be focused to first end face 231 greater than the sectional area of first end face 231, then is directed to this identification pattern 24 places, makes identification pattern 24 luminous and do not need extra light source.The light lead body 23 outer reflex reflectors 235 that also can be provided with, but as attaching the reflection lacquer according to reflective paster or coating reflection ray, to reach the purpose that the light that will pass second end face 232 is directed to first end face 231 fully.
By above identification pattern light-emitting device of the present invention, really can reach the light source of guiding in the display to identification pattern, making that this identification pattern is luminous and do not need extra light source, is the defective that overcomes prior art in fact, satisfies the demand of industrial community and improves industrial competitiveness.
The above only is preferred embodiment of the present invention, and all equalizations of doing according to claims of the present invention change and modify, and all should belong to the covering scope of patent of the present invention.
