The specific embodiment
For further disclosing concrete technology contents of the present utility model, elaborate by reference to the accompanying drawings.
As shown in Figures 3 and 4, substantially, the utility model guiding device comprises a light guide seat 1 and at least one light shield 2.
Light guide seat 1 is aforementioned known member, and it is with transparent polymer material, for example acryl Unitary injection formed.This light guide seat 1 bottom has the setting of a pedestal 11, at least one pair of clasp 12 is stretched out in these pedestal 11 both sides, bottom surface, end face stretches out at least two light-guiding pillars 13 abreast, separately in these corresponding each light-guiding pillar 13 positions, pedestal 11 bottom surfaces, offer respectively a storage tank 14, and differing from known component technology, this light guide seat 1 is a bit of flange 15 of the longitudinal projection of a wherein openend of each storage tank 14 forward and backward sides.
Light shield 2 is light tight color, and for example black macromolecular material is made, and it has a rectangle framework 21, and this rectangle framework size is equal to storage tank 14, to can be sheathed in storage tank 14.This framework 14 is positioned at these light-guiding pillar 13 positions and is longitudinally provided with a through hole 22, so that accommodating light emitting diode (LED).For making this light shield 2 be incorporated into this light guide seat 1, and unlikely coming off, therefore, the forward and backward pleurapophysis of this framework 21 is established at least one pair of grab 23, be preferably the forward and backward side of this framework 21 diagonal angle distal process and establish at least one pair of grab 23, and utilize each to grab 23, to be buckled in pedestal 11 front and rear edges, each light shield 2 is sheathed in storage tank 14, and be buckled in pedestal 11, to form positioning relation securely.
Further, flange 15 positions in the corresponding storage tank 14 of each light shield 2 end faces are provided with groove 24, to form opposite joining relation with flange 15, directionality when providing each light shield 2 to install, for example, when these light shield 2 top surface plane are connected to the flange of storage tank 14, will make cannot be buckled in pedestal 11 with the grab 23 on one side (leading edge), make this light shield 2 form the skewed of non-opposite joining relation.
As shown in Figure 5, be that three light shields 2 are installed in respectively to the stereogram in this light guide seat 1 bottom storage tank 14, that is the finished figure of the utility model guiding device.
As shown in Figure 6, be this guiding device to be incorporated into the profile of printed circuit board (PCB), these printed circuit board (PCB) 3 surfaces have three sheet LED31; 1 of this light guide seat utilizes a pair of clasp 12 of these pedestal 11 both sides, bottom surface to be buckled in the plate hole 32 of these printed circuit board (PCB) 3 acquiescences, this light guide seat 1 is fixedly arranged on this printed circuit board (PCB) 3, each storage tank 14 rectangle framework 21 of a sheathed light shield 2 separately wherein, and interior confession one LED31's of the through hole 22 of each framework 21 is accommodating.
After a LED31 lights, its light is subject to the bridging effect of this light tight framework 21, and can only pass through through hole 22, and advances towards the light-guiding pillar 13 of this LED31 top, and by light conduction the free end to this light-guiding pillar 31, be beneficial to indication.
So, via enforcement of the present utility model, its effect gaining is, the storage tank of this light guide seat supplies, after light tight light shield combination, to make can only be passed through through hole by the coated light that LED produced of the framework of light shield, and advance towards the light-guiding pillar of this LED top, and reason light guide seat is not transparence, and allow light because reflection and diffusion effect form the puzzlement of printing opacity, light can be concentrated in single light-guiding pillar, thereby solve the problem that identification is obscured simultaneously.Meanwhile, because each LED is coated by a light shield, to avoid the problem of mixed light that a plurality of LED is caused.
The utility model discloses, and is a kind of of preferred embodiment, and local change or modification and come from technological thought of the present utility model and be what those skilled in the art were easy to know by inference such as, does not all take off claim category of the present utility model.
