Abstract
The utility model relates to a car audio, particularly to a knob light guide device, belonging to the technical field of optical instrument equipment. The knob light guide device comprises a spiral ring body with a through hole, the lower surface of the spiral ring body has zigzag stripes, a light guide path is arranged at one end of the spiral ring body, a light reflecting plane is arranged at one end of the light guide path, and a semi-circular light ingoing plane is arranged at the lower part of the light reflecting plane. The knob light guide device utilizes the structural characteristics of light guide by the optical principle and the effective transmission of light; and light rays from a light source pass through a passage which spirals upwards clockwise, and then light rays are transmitted upwards through the continuous reflection and diffusion of the zigzag structure. The energy of the light source is utilized fully, the light energy loss is reduced, and brightness and uniformity of light permeating a luminous environment are improved.
Description
Technical field
The utility model relates to a kind of automobile audio, is specifically related to a kind of knob guiding device, belongs to the optical instrumentation technical field.
Background technology
At present, at the automobile audio production industry, the appearance design of sound equipment will be complementary with the interior trim of car load, and gorgeous cold light source is exactly very important composition wherein.Outward appearance for automobile audio; Polishing is extremely important for the influence of a sound equipment; Each tame automobile production industry so in limited design space, not only will satisfy brightness requirement, also will satisfy the requirement of light source uniformity coefficient to its requirement unusual height all simultaneously.General knob luminous environment all adopts the multiple spot led light source to realize in order to satisfy brightness and uniformity coefficient, so just can't avoid the phenomenon of optically focused and bright dark inequality to occur.
Summary of the invention
The purpose of the utility model is in order to overcome above-mentioned existing weak point; A kind of knob guiding device is provided, and this knob guiding device comprises that one has the spiral ring body of through hole, and the lower surface of described spiral ring body has the sawtooth striped; One end of spiral ring body has the leaded light footpath; One end in leaded light footpath has reflective surface, and the bottom of described reflective surface has one semicircle to advance the light face, and this device utilizes the design feature of effective conduction of optical principle leaded light and light; The light of light source constantly reflects with scattering through laciniation and upwards transmits through the passage on the clockwise screw.Make full use of energy of light source, reduced light energy losses, and improved brightness and the uniformity coefficient that sees through luminous environment light.
The utility model solves the technical scheme that its technical matters adopted: a kind of knob guiding device; It is characterized in that: this device comprises that one has the spiral ring body of through hole; The lower surface of described spiral ring body has the sawtooth striped; One end of spiral ring body has the leaded light footpath, and an end in leaded light footpath has reflective surface; The bottom of described reflective surface has one semicircle to advance the light face; In the described spiral ring body knob supporting construction is arranged.
The surface of described spiral ring body is astigmatic atomizing face.
Describedly advance on the light face to be evenly equipped with the sawtooth striped.
Be evenly equipped with several steps on the described knob supporting construction.
The utility model has the advantages that: adopt this knob guiding device, make light source when getting into the leaded light footpath through the first road scattering, transmit along spiral sawtooth passage through direct reflection light; Exhale through atomizing face at last; Improve the utilization of luminous energy effectively,, improved the brightness and the uniformity coefficient on knob luminous environment surface through the transmission and the optical scattering of different structure; Simultaneously only use a led light source, reduced production cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the utility model perspective view;
Fig. 2 is the utility model vertical view;
Fig. 3 is the utility model front elevation.
Among the figure 1, advance the light face, 2, reflective surface, 3, the leaded light footpath, 4, the spiral ring body, 5, astigmatic atomizing face, 6, the knob supporting construction, 61, step, 7, through hole.
Embodiment
As shown in the figure: a kind of knob guiding device, this device comprise that one has the spiral ring body 4 of through hole 7, and the lower surface of described spiral ring body has the sawtooth striped, and an end of spiral ring body has leaded light footpath 3, and an end in leaded light footpath has reflective surface 2; The bottom of described reflective surface has one semicircle to advance light face 1; In the described spiral ring body knob supporting construction 6 is arranged.
The surface of described spiral ring body 4 is astigmatic atomizing face 5.
Describedly advance on the light face 1 to be evenly equipped with the sawtooth striped.
Be evenly equipped with several steps 61 on the described knob supporting construction 6.
The course of work: light gets into the sawtooth via the certain angle on surface from advancing the light face; Light is launched at the contact reflective surface, and most light vertically get into the leaded light footpath, directly gets into the sawtooth of spiral ring body via leaded light; Light spirals clockwise in spiral ring body sawtooth and upwards transmits; Through the continuous reflection of serrated face, the degree of transitivity that refraction has increased light, penetrate from astigmatism atomizing face at last, realize the polishing requirement.
Claims (4)
