Abstract
The invention discloses a light-emitting body type thin film switch which comprises a PET panel layer, a light guiding layer and circuit layers. The lower end of the PET panel layer is sequentially provided with a face adhesive layer, the light guiding layer, the circuit layers and a PET bottom board layer. The light guiding layer is provided with an LED assembly. The circuit layers comprise the upper circuit layer and the lower circuit layer. A PET double-faced adhesive layer is arranged between the upper circuit layer and the lower circuit layer. The light-emitting body type thin film switch has the advantages that LED lamps are used, so that electricity is saved and the service life is long; the LED lamps are connected in parallel so that when one LED lamp is broken, other LED lamps can also work normally; LED wires are arranged on the lower circuit layer, so that the wires are prevented from being disordered; circular holes are formed around the position, provided with a switch, of the PET panel layer so that air inside the PET panel layer can be discharged through the circular holes when the PET panel layer is pressed; meanwhile, the ventilation function is achieved, so that problems caused by overheating of the LED lamps are solved and the thin film switch is effectively protected.
Description
Technical field
The present invention relates to a kind of thin film switch, relate in particular to a kind of luminous build thin film switch.
Background technology
Thin film switch is an operating system that integrates keypress function, indicator elment, instrument panel, is widely used in the instrument of telecommunications, electronic measurements, Industry Control, Medical Devices, auto industry, intelligent toy, the fields such as household electrical appliance.The thin film switch of producing is in the market various informative: although plane is without sense of touch type long service life, there is no sense of touch; Although film convex surface sense of touch type has good sense of touch, useful life is short; Although chimb frame is specious without sense of touch type, third dimension is strong, without sense of touch type etc.It is exactly cannot remove in darker place the position of seeing switch that these thin film switches also have a defect, therefore, the invention provides a kind of new technical scheme and addresses the above problem.
Summary of the invention
The invention provides a kind of luminous build thin film switch.
The technical solution used in the present invention: a kind of luminous build thin film switch comprises PET panel layer, optical waveguide layer and circuit layer, PET panel layer lower end is provided with optical waveguide layer, face glue-line, circuit layer and PET backplane level successively, optical waveguide layer is provided with LED luminescence component, circuit layer comprises circuit layer and lower circuit layer, between upper circuit layer and lower circuit layer, is provided with PET layers of two-sided.
Above-mentioned LED luminescence component comprises LED lamp and LED line, LED lamp passes through epoxy resin gluing on optical waveguide layer, the position of the switch that the corresponding PET panel layer in position that LED lamp is installed is provided with, PET panel layer is provided with on the position of switch and makes transparent processing, and LED line is located in lower circuit layer.
Above-mentioned LED lamp adopts parallel way to be connected; On above-mentioned PET panel layer, the position of switch has circular hole around.
Beneficial effect of the present invention: adopt LED lamp; power saving and long service life, LED lamp adopts parallel way to be connected, after a LED lamp has been broken; remaining waits and still normally works; LED line is located to lower circuit layer, can prevents the confusion of circuit, on PET panel layer, around the position of switch, have circular hole; when pressing, the air of PET panel layer inside can be discharged by circular hole; play logical wind action simultaneously, prevent the overheated problem causing of LED lamp, effectively protected thin film switch.
