Abstract
The invention provides an integrated multidirectional LED light guide system which comprises a light guide structure and an LED light-emitting chip. The light guide structure is integrally formed and provided with multiple light guide paths, the LED light-emitting chip is bonded and fixed on a printed circuit board, the light guide structure is provided with a light receiving end and multiple illuminating ends, the light receiving end is adjacent to the LED light-emitting chip to receive a light source, the illuminating ends are respectively corresponding to keys or indicating buttons of an electronic product, and the light guide paths are formed between the light receiving end and the illuminating ends. By using the integrally-formed light guide structure with the light guide paths, the integrated multidirectional LED light guide system can obtain preset illuminating effect only by using a single LED or few LEDs at little cost; in addition, by the design, a circuit board structure using multiple LED perforated structures is also simplified.
Description
Technical field
The present invention relates to a kind of illumination optical structure, particularly a kind of integrated type multi-directional LED light-conducting system simple in structure, with low cost.
Background technology
Current electric equipment products, comprise portable mobile communication product, handheld electric products, various household electrical appliance etc., all have LED(light emitting diode) indication or backlight function, such as the demonstration backlight of mobile phone key, the various function instruction button demonstration backlight on household electrical appliance etc.This demonstration backlight or function indicating structure are generally to use a LEDs or use a LEDs in conjunction with the corresponding button of single light-guiding pillar or an instruction button.As shown in Figures 1 and 2, on the display floater 100 of an electronic product, there are a plurality of function instruction button 101,102,103 and 104, and on its circuit board corresponding four LEDs 300 that are provided with just on 200.This single-piece light guide structure can allow small volume, low-cost surface bonding LED to be applied on electronic product, but the problem of its existence is, when display button backlight or instruction button, just need to use plurality of LEDs when more, so, cost will rise; Meanwhile, while using plurality of LEDs, just need to support, on circuit board, a plurality of perforation structures are set at it, so take limited board area, increase the design complexities of circuit board; In addition, when interiors of products structure is more complicated, this surface bonding LED can not be along estimating that the path designing provides illumination to suitable region.
Summary of the invention
The object of the invention is the high problem of cost producing in order to solve existing use plurality of LEDs, and solve in interiors of products structure compared with making the surface stickup LED on circuit board provide backlight or function button indication along complicated route conduction LED light under complicated situation.
To achieve the object of the present invention, the invention provides a kind of integrated type multi-directional LED light-conducting system, it comprises the integrated light guide structure with a plurality of guide path warps, bonding anchors at the LED luminescent wafer on printed circuit board (PCB), described light guide structure has optical receiving end and a plurality of illumination end, described optical receiving end adjoins described LED luminescent wafer to accept light source, described a plurality of illumination end corresponds to respectively button or the instruction button of electronic product, forms described guide path warp between described optical receiving end and described illumination end.
Preferably, described optical receiving end is concave structure, described LED luminescent wafer be arranged at least partly described concave structure.
Preferred again, described illumination end has the surface texture that makes divergence of beam.
The present invention is by using the integrated light guide structure with a plurality of guide path warps, uses single or few LED can obtain default illuminating effect and only need to expend some costs; The board structure of circuit that uses a plurality of LED perforation structures has also been simplified in this design simultaneously in addition.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, the present invention is aforesaid will be become apparent with other object, feature and advantage.Wherein:
The function button of display floater that Figure 1 shows that the electronic product of prior art arranges schematic diagram;
Corresponding circuit board and the LED of electronic product that Figure 2 shows that Fig. 1 arranges schematic diagram;
Figure 3 shows that the structural representation of an embodiment of integrated type multi-directional LED light-conducting system of the present invention;
Figure 4 shows that the structural representation of another embodiment of integrated type multi-directional LED light-conducting system of the present invention;
Figure 5 shows that the structural representation of another embodiment of integrated type multi-directional LED light-conducting system of the present invention.
The specific embodiment
Structure of the present invention and advantage are described in detail in conjunction with specific embodiments in detail as follows.
The structural representation of an embodiment of integrated type multi-directional LED light-conducting system of the present invention as shown in Figure 1, it comprises the integrated light guide structure 30 with a plurality of guide path warps, bonding anchors at the LED luminescent wafer 20 on printed circuit board (PCB) 10, described light guide structure has optical receiving end 32 and a plurality of illumination end 34, described optical receiving end 32 adjoins described LED luminescent wafer 20 to accept light source, described a plurality of illumination end 32 corresponds to respectively button or the instruction button of electronic product, forms described guide path warp between described optical receiving end 32 and described illumination end 34.
In another preferred embodiment, as shown in Figure 2, described optical receiving end 32 ' is concave structure, described LED luminescent wafer 20 be arranged at least partly described concave structure.
In another preferred embodiment, as shown in Figure 3, described illumination end 34 ' has the surface texture that makes divergence of beam.
Light guide structure of the present invention can be by utilizing transparent plastic to be made of one piece, and polishes through high light with light guide in its optical receiving end surface, and illumination end has the light that surface texture comes along the conduction of leaded light path in order to scattering.
The present invention is not limited to described embodiment, and those skilled in the art, not departing from spirit of the present invention openly in scope, still can do some corrections or change, therefore the scope that the scope of the present invention limits with claims is as the criterion.
