Abstract
Hemisphere face cylindricality light-guiding pillar, comprise light-guiding pillar end face, guide-lighting cylinder and light-guiding pillar bottom surface, light-guiding pillar end face is semisphere post block, and the lower end of light-guiding pillar end face connects guide-lighting cylinder, light-guiding pillar end face diameter is less than guide-lighting column diameter, and guide-lighting cylinder lower end is light-guiding pillar bottom surface; The light-guiding pillar bottom surface of hemisphere face cylindricality light-guiding pillar adopts hemispherical groove structure, and when hemisphere face cylindricality light-guiding pillar is adjacent to the paster LED on circuit board, paster LED is embedded in the hemispherical groove of light-guiding pillar bottom surface.Hemisphere face cylindricality light guide column structure is simple, can the light of paster LED scattering surrounding be gathered in hemisphere face cylindricality light-guiding pillar, improve spotlight effect, increase light firing angle degree at bright dipping end simultaneously, solve traditional cylindricality light-guiding pillar astigmatism, light leak is serious and visible angle is narrow problem, be applied in intelligent electric instrument, not only light guide effect is good, and is convenient to batch installation.
Description
Technical field
The present invention relates to a kind of hemisphere face cylindricality light-guiding pillar on intelligent electric instrument, the light concentration class that especially can improve paster LED realizes the hemisphere face cylindricality light-guiding pillar improving optical efficiency.
Background technology
At present, intelligent electric instrument has replaced traditional pointer meters to be applied in the environment such as Industry Control, power distribution room gradually, the registration state that conveniently user's reading instrument is current, general industry designer can design some LED on instrument face plate, and these LED may be used for the unit or the information that indicate current registration.These LED general can adopt contact pin type welded encapsulation on circuit boards, and cannot carry out the circuit board of wave-soldering for some two-sided pasters, can only carry out manual welding by manual type.For the ease of production of machinery, product is also had to start to replace direct insertion LED with the LED of paster.But paster LED lacks the guide-lighting head of direct insertion LED, cause occurring these situations such as astigmatism, light leak, luminance shortage, be unfavorable for user's reading.
Summary of the invention
The applicant, for above-mentioned problem, is studied improvement, provides a kind of hemisphere face cylindricality light-guiding pillar.This hemisphere face cylindricality light guide column structure is simple, is convenient to produce and install, and has both improve the light collection efficiency of light inputting end paster LED, increases again the luminous scattering angle of bright dipping end.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is as follows:
Hemisphere face cylindricality light-guiding pillar, comprise light-guiding pillar end face, guide-lighting cylinder and light-guiding pillar bottom surface, light-guiding pillar end face is semisphere post block, and the lower end of light-guiding pillar end face connects guide-lighting cylinder, light-guiding pillar end face diameter is less than guide-lighting column diameter, and guide-lighting cylinder lower end is light-guiding pillar bottom surface; The light-guiding pillar bottom surface of hemisphere face cylindricality light-guiding pillar adopts hemispherical groove structure, and when hemisphere face cylindricality light-guiding pillar is adjacent to the paster LED on circuit board, paster LED is embedded in the hemispherical groove of light-guiding pillar bottom surface.
Beneficial effect of the present invention is as follows:
Structure of the present invention is simple, can the light of paster LED scattering surrounding be gathered in hemisphere face cylindricality light-guiding pillar, improve spotlight effect, increase light firing angle degree at bright dipping end simultaneously, solve traditional cylindricality light-guiding pillar astigmatism, light leak is serious and visible angle is narrow problem, be applied in intelligent electric instrument, not only light guide effect is good, and is convenient to batch installation.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Fig. 2 is light path schematic diagram during the present invention applies.
1. light-guiding pillar end faces, 2. guide-lighting cylinder, 3. light-guiding pillar bottom surface in figure, 4.LED light path 1,5.LED light path 2.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, clear, complete description is carried out to the technical scheme in the embodiment of the present invention.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Hemisphere face cylindricality light-guiding pillar as shown in Figure 1, comprise light-guiding pillar end face (1), guide-lighting cylinder (2) and light-guiding pillar bottom surface (3), light-guiding pillar end face (1) is semisphere post block, the lower end of light-guiding pillar end face (1) connects guide-lighting cylinder (2), light-guiding pillar end face (1) diameter is less than guide-lighting cylinder (2) diameter, and guide-lighting cylinder (2) lower end is light-guiding pillar bottom surface (3); The light-guiding pillar bottom surface (3) of hemisphere face cylindricality light-guiding pillar adopts hemispherical groove structure.
The present invention is in use as Fig. 2, and when hemisphere face cylindricality light-guiding pillar installs and is close on circuit boards, paster LED is embedded in the hemispherical groove of light-guiding pillar bottom surface (3).When this paster LED is luminous, light is incident from light-guiding pillar bottom hemispheric groove.Wherein, the LED light road 1(4 perpendicular to circuit board) inject light-guiding pillar after, directly penetrated from light-guiding pillar end face (1) by guide-lighting cylinder (2); And the LED light road 2(5 of other angles) when injecting on guide-lighting cylinder (2) inside surface, through constantly reflecting, make light arrive light-guiding pillar end face (1) injection.As a complete unit, the light of paster LED directive surrounding effectively gathers together finally from light-guiding pillar end face (1) to surrounding injection shell by hemisphere face cylindricality light-guiding pillar.
Structure of the present invention is simple, can the light of paster LED scattering surrounding be gathered in hemisphere face cylindricality light-guiding pillar, improve spotlight effect, increase light firing angle degree at bright dipping end simultaneously, solve traditional cylindricality light-guiding pillar astigmatism, light leak is serious and visible angle is narrow problem, be applied in intelligent electric instrument, not only light guide effect is good, and is convenient to batch installation.
The foregoing is only present pre-ferred embodiments, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
