Abstract
The utility model relates to an LED lamp packaging structure on a thin-film switch, which is provided with an LED lamp fixed on the thin-film switch. The LED lamp packaging structure on the thin-film switch is characterized in that the LED lamp packaging structure extends towards the periphery thereof by adopting the center point of the top end of the LED lamp as the center; the outer surface of the LED lamp is provided with an LED light outlet hole, a black oil ink layer and a black light-shielding resin layer in sequence; the black oil ink layer and the black light-shielding resin layer are respectively adhered on the outer surface of the LED lamp; the bottom end of the black light-shielding resin layer is fixedly adhered on the thin-film switch; and the black light-shielding resin layer is a black epoxy resin layer or a black silicon rubber layer or a black polyester resin layer or a black polyurethane resin layer or a black acrylic acid resin layer. The LED lamp packaging structure does not need to add the procedures of manufacturing a silica gel lamp cover and manual sticking, and has simple production technique.
Description
Technical field
The utility model relates to a kind of LED lamp encapsulation structure, LED lamp encapsulation structure on particularly a kind of thin film switch.
Background technology
The LED light of computer membrane keyboard is encapsulated on the thin film switch usually, they when membrane keyboard is worked, provide vertically to the spot light indicative function.The LED that generally adopts in the industry is encapsulated as the complete encapsulating structure of UV resin at present.It is on thin film switch, with the UV resin LED is sealed fully, and the UV resin solidifies through UV-irradiation, thereby reaches the encapsulation purpose.UV resin after the curing is transparent, thereby keyboard when work, and LED has bigger light intensity on the keyboard vertical direction, played indicative function.But with the keyboard parallel direction on, each contiguous orientation of LED also is illuminated, and has influenced keyboard and bring user's specialty sense and attractive in appearance when work.
At present, in the industry solution to the problems described above be seal fully at the UV resin, behind the photocuring, paste a black shading silica gel lampshade more in the top, lampshade only has a very little light hole on the top, thereby the light that guarantees LED only penetrates in the keyboard vertical direction, the light of all the other directions is then blocked by lampshade, and then has solved the problems referred to above.But the shortcoming of this method is to need the manufacturing of extra increase silica gel lampshade to paste operation with manual, and technology is comparatively loaded down with trivial details.And the lampshade light hole is very little, occurs light hole easily when pasting and the LED luminous site is departed from, and what have influence on LED goes out luminous intensity even photoresistance is disconnected, has reduced yield rate.In addition, the silica gel lampshade has increased the local height of thin film switch greatly, has had influence on the feel of the contiguous button of LED.
Summary of the invention
The utility model provides LED lamp encapsulation structure on a kind of thin film switch, and purpose is to solve the prior art problem, and a kind of do not need additionally to increase manufacturing of silica gel lampshade and the manual operation, production technology simple LED lamp encapsulation structure of pasting are provided.
The utility model technical scheme that adopts of dealing with problems is:
LED lamp encapsulation structure on a kind of thin film switch, has the LED lamp that is fixed on the thin film switch, on LED lamp outer surface, be provided with LED light hole, black ink layer, black shading tree resin layer with LED lamp top central point successively for its extension all around of middle mind-set, black ink layer and black shading tree resin layer be respectively attached on the LED lamp outer surface, and black shading tree resin layer bottom is adhered to and is fixed on the thin film switch.
Black shading tree resin layer is black epoxy resin layer or black silicon rubber layer or black polyester tree resin layer or black polyurethane tree resin layer or black acroleic acid resin.
The beneficial effects of the utility model: constitute half encapsulating structure with black shading tree resin layer the LED lamp is enclosed in wherein, the side of LED lamp is covered in, and the unsheltered part of LED lamp is covered by applying black ink, and offer a LED light hole on the ink lay top, whole process of production does not need additionally to increase the manufacturing of silica gel lampshade and pastes operation with manual, and production technology is simple.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a profile of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
LED lamp encapsulation structure on a kind of thin film switch as shown in Fig. 1, Fig. 2, has the LED lamp 2 that is fixed on the thin film switch, on LED lamp 2 outer surfaces, be provided with LED light hole 5, black ink layer 4, black epoxy resin layer 3 with LED lamp 2 top central points successively for its extension all around of middle mind-set, black ink layer 4 and black epoxy resin layer 3 are attached to respectively on LED lamp 2 outer surfaces, and black epoxy resin layer 3 bottom are adhered to and are fixed on the thin film switch.Described epoxy resin layer 3 is encapsulated in LED lamp 2 half wherein, LED lamp 2 lateral parts are hidden, and the LED lamp top in the present embodiment is the plane, produces for convenient, its epoxy resin layer 3 tops parallel with the peak of LED lamp 2, and promptly epoxy resin layer 3 parallels with the summit of LED lamp.If LED lamp 2 tops are cambered surface, then epoxy resin layer 3 top will be lower than the summit of LED lamp 2, reduce the thin film switch local height like this, guarantee to push feel.Light hole 5 is positioned at the central point on LED lamp top in this structure, and purpose is in order to make light hole 5 perpendicular to thin film switch 1, to guarantee that light can vertically penetrate.Described black epoxy resin layer 3 also can be black silicon rubber layer or black polyester tree resin layer or other shading tree resin layers such as black polyurethane tree resin layer or black acroleic acid resin.
