A kind of light emitting control transmission mechanism
Technical field
The utility model relates to a kind of transmission mechanism, particularly, relates to a kind of light emitting control transmission mechanism.
Background technology
Existing luminous transmission mechanism comprises panel, and panel is provided with knob, can carry out gear through knob and regulate.Panel rear is provided with illuminating source; And adopt fixing light source to carry out the luminous lighting prompting usually through printing opacity sign on the panel and the light conductor on the knob; Therefore the light source colour that is shown on panel and the knob is normally fixed; Can not point out according to the different gears at knob place, the user still is difficult to distinguish the present located gear under dark surrounds, therefore needs to do to improve further.
The utility model content
The problem that the utility model will solve is: providing a kind of to the problem of above-mentioned existence can carry out different luminous promptings, light emitting control transmission mechanism simple in structure according to different gears.
The technical scheme that the utility model adopted is: a kind of light emitting control transmission mechanism is provided; Comprise knob, panel, gear light conductor and circuit board (printed circuit board); Said knob is arranged on the said panel; Said panel is provided with the printing opacity sign, and said gear light conductor and circuit board are arranged on said panel rear, and said circuit board is provided with light source and connects the potentiometer of control light source luminescent; Said gear light conductor two ends respectively with said knob and said circuit board on potentiometer link to each other, be provided with a knob printing opacity piece behind the said knob.
Further; Printing opacity sign light source and gear light conductor light source that printing opacity sign on corresponding said panel on the said circuit board and said gear light conductor rear portion are respectively equipped with different colours; Said potentiometer connect the said gear light conductor light source of control carry out luminous, thereby can show the luminous prompting of different colours when being implemented in different gear.
Preferably, the light source on the said circuit board is a light emitting diode.
Compared with prior art; The light emitting control transmission mechanism that the utility model provides can make the knob indication present different luminous prompting effects (brightness and color) with the panel sign through adjustment gear light conductor light, color under the constant situation of illuminating source color; And simple in structure, utilize potentiometer just can reach predetermined function output requirement through programming; In addition, this mechanism reliable operation, can reach more than 50000 times service life.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing:
Embodiment: shown in Fig. 1 to 3, the light emitting control transmission mechanism in the present embodiment comprises knob 1, panel 3, gear light conductor 4 and circuit board 5.
The main decoration functions that rise of panel 3, panel 3 is provided with the printing opacity sign, can printing opacity when the light source luminescent of circuit board 5, show the home position when knob 1 rotates.
Knob 1 is arranged on the panel 3 as input, is provided with a knob printing opacity piece 2 behind the knob 1, when knob 1 rotates, plays indicative function, when the light source luminescent of circuit board 5, can pass through.
Circuit board 5 is arranged on panel 3 rear portions, and circuit board 5 is provided with LED (light emitting diode) light source and potentiometer, and it is luminous that potentiometer connects the control led light source.Particularly; Light source comprises printing opacity sign light source and gear light conductor light source; The position at the printing opacity sign rear portion on the corresponding panel 3 of printing opacity sign light source, the position at gear light conductor light source respective notch light conductor 4 rear portions, potentiometer connects control gear light conductor light source and carries out luminous.
Gear light conductor 4 is arranged on panel 3 rear portions; The two ends of gear light conductor 4 respectively with knob 1 and circuit board 5 on potentiometer link to each other; Each location, position and counter plate 3 printing opacity colors played corrective action when knob 1 rotated, and the potentiometer that drives simultaneously on the circuit board 5 is realized function output.
Knob 1 and gear light conductor 4 are connected, promptly drive gear light conductor 4 by knob 1, the potentiometer that drives on the circuit board 5 by gear light conductor 4 again, thus reach function output.Because knob 1 is when different gear, potentiometer resistance is different, so the light source luminescent on the circuit board 5 is different, gear light conductor 4 luminosity, color difference.Therefore can under the constant situation of emitting led color, make the knob indication present different illumination effects (brightness and color) with the panel sign through 4 brightness of adjustment gear light conductor, color.
