The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
embodiment one.
Shown in Fig. 1～4, the visible light module of the utility model comprises light-emitting component 11 and light-guide device 12, and said light-emitting component 11 is by being located at the side of said light-guide device 12, and the bottom surface of said light-guide device 12 is provided with diffuse reflector 13.The logical light face 126 of said light-guide device 12 is provided with even light film 121, and the side of said light-guide device 12 is provided with reflective membrane 122, and the bottom surface of said diffuse reflector 13 is provided with reflective membrane 122.Be laid with a plurality of diffuse reflection point films 131 on the diffuse reflector 13, the area of the diffuse reflection point film 131 of contiguous said light-emitting component 11 is less than the area away from the diffuse reflection point film 131 of said optical element.
The principle of visible light module 1 is through reflection and the refraction principle of light in medium a spot light to be become an area source.When the light of light-emitting component 11 is injected light-guide device 12 from the side end face; Make light in light-guide device 12 inside the reflection through light and refraction principle spot light is dispersed the conduction expansion; The diffuse reflection point film 131 of the Special matrix layout of diffuse reflector 13 is that the light quantity that lets a spot light produce can evenly be conducted reflection; The reflective membrane 122 that is arranged on diffuse reflector 13 bottom surfaces and light-guide device 12 sides is for the light that will reflect light-guide device 12 is reflected into light-guide device 12 again, thereby increases the loss that luminous flux reduces light quantity.Be arranged on the even light film 121 on the logical light face 126, help the light that reflects this face is once disperseed uniformly, thereby form the area source of a uniform luminance.The utlity model has simple in structurely, light loss is little, good energy-conserving effect, the advantage of the succinct reliable and luminous good evenness of the variation of luminous color.
The light-emitting component 11 of present embodiment is a LED; Because LED is fixed on the FPC 24 of keyboard; Light-emitting component 11 can stick on the side of light-guide device 12 through cloth insertion sheet, thereby also can just can make light-emitting component 11 by being located at the side of light-guide device 12 through the clamping control light-emitting component 11 of FPC 24 and light-guide device 12 and the position between the light-guide device 12; Install and convenient disassembly, be convenient to maintenance.
The diffuse reflector 13 of present embodiment is printed on the bottom surface of light-guide device 12 through mode of printing.Preferred embodiment diffuse reflector 13 is one-body molded, simple in structure with light-guide device 12 as one, and diffuse effect is good.
As one preferred embodiment, by being provided with the different light-emitting component of glow color 11, the area of the diffuse reflection point film 131 of said diffuse reflector 13 reduces from the centre and arranged on left and right sides end of the said light-guide device 12 of present embodiment to the left and right sides gradually respectively.
Because light is luminous energy meeting loss in reflection process; Area from the near more diffuse reflection point film 131 of light-emitting component 11 is more little; Area from light-emitting component 11 diffuse reflection point film 131 far away more is big more, so the reflective surface area of diffuse reflection point film 131 far away more helps light more greatly and evenly reflects away.In light-guide device 12 two side ends one light-emitting component 11 is set respectively; When two light-emitting components 11 are different glow color; Just can produce the colored bar shaped visible light module 1 of colour mixture, the light intensity variation of controlling two light-emitting components 11 through control circuit just can produce colour along the line to moving or bright dark variation, forms dynamic color change effect with this; Can form a beautiful fashion electronic product through bright and colourful color change, greatly promote product level.Certainly, also can two identical light-emitting components 11 of glow color be set in light-guide device 12 two side ends, just be monochromatic bar shaped visible light module 1.
The light-guide device 12 of present embodiment includes transparent light guide substrate 123, and said light-guide device 12 in the form of sheets.Transparent light guide substrate 123 is to be made up of at the PMMA of interior generation total reflection effect plastic material a kind of special light that can let, and simple in structure, reflecting effect is good.
embodiment two.
Shown in Fig. 4～5; The difference of present embodiment and embodiment one is; The light-guide device 12 of present embodiment comprises hyaline layer 124 and white reflecting layer 125, and said hyaline layer 124 takes shape in the top of said white reflecting layer 125 with the double-shot moulding mode, and said light-guide device 12 is strip.
As shown in Figure 5, the welding moulding cross section of hyaline layer of present embodiment 124 and white reflecting layer 125 is type or the arc that raises up linearly, and simple in structure, working (machining) efficiency is high.
The remainder of present embodiment is identical with embodiment one, repeats no more here.
embodiment three.
Shown in Fig. 1～6, the illuminated keyboard of the utility model comprises the keyboard body, and said keyboard body is provided with logical light channel structure, and said logical light channel structure below is provided with visible light module 1.Keyboard and visible light module 1 organic combination are in the same place; Just can produce the illuminated keyboard product of different-effect; Illuminated keyboard greatly is beneficial in environment with dark light and also can as usually uses; Can form a beautiful fashion electronic product through bright and colourful color change, greatly promote the keyboard level.Through different luminous configurations, can make illuminated keyboard seem more attractive in appearance and then strengthen its sales volume.
The logical light channel structure of present embodiment comprises transparent button 21 that the skin that sets gradually from top to bottom sprays has enamelled coating, opaque loam cake 22, transparent silica gel switch 23 and transparent FPC 24, and said button 21 tops are provided with the character that forms through radium-shine carving erosion.Just formed the logical light channel structure of a spcial character with the functor group of upper keyboard immediately; When being arranged on visible light module 1 electrified light emitting of this logical light channel structure below; Its light just can appear keyboard through this logical light channel structure, on keyboard appearance, produces the effect of keypad character visible light.
