The specific embodiment
Below, in conjunction with the accompanying drawing and the specific embodiment, the utility model done further describing, so that clearerly understand the utility model technological thought required for protection.
As depicted in figs. 1 and 2, the controlled light fixture of a kind of brightness, the pcb board (figure does not mark) that it comprises light source (figure does not draw), lamp stand 1, base 7, code switch 6, driving sleeve 5 and single-chip microcomputer is installed.
The articulated section 2 of lamp stand 1 articulates through the installation portion 3 of a pivot 4 with base 7, and promptly lamp stand 1 can rotate with respect to base 7 around pivot 4, with the light angle between adjustment light source and the desktop.
The stiff end of driving sleeve 5 is fixedly connected with articulated section 2; The driving end of driving sleeve 5 is fixedly connected with the knob 61 of stirring of code switch 6; Concrete, the stiff end of driving sleeve 5 is provided with the projection 52 that is provided with along lamp stand 1 length direction, and the driving end of driving sleeve 5 is provided with the groove 51 that knob 61 cooperates of stirring with code switch 6; Projection 52 is pegged graft with the articulated section 2 of lamp stand 1, groove 51 with stir knob 61 sockets.
The rotation of the rotation of lamp stand 1, driving sleeve 5 and the rotation of stirring knob 61 all are positioned on the same axis.
The electrical pin 62 of code switch 6 electrically connects with pcb board, and pcb board is positioned at base 7 (also can be arranged on lamp stand 1 to pcb board); Light source and pcb board electrically connect.The light source of present embodiment can adopt the electric driven for emitting lights body of LED lamp or tengsten lamp or other.
The code switch 6 of present embodiment is stepless transfer switch, can realize minimum 256 grades brightness requirement of light regulation.
Present embodiment is assemblied in driving sleeve 5 between code switch 6 and the lamp stand 1, can play transmission and the effect that reduces structure precision.Like this, when lamp stand 1 rotated, because driving sleeve 5 is just in time on the rotation of lamp stand 1, and driving sleeve 5 had engagement fit with lamp stand 1, so lamp stand 1 rotates and can drive driving sleeve 5 and rotate; Equally; When rotating, driving sleeve 5 also can drive the rotation of stirring knob 61 of code switch 6 through engagement; Thereby realized that lamp stand 1 rotates the knob 61 of stirring that drives code switch 6 and rotates, simultaneously the electrical pin 62 through code switch 6 with realize that lamp stand 1 rotates to drive simultaneously cooperating of single-chip microcomputer and adjust light fixture and the output of light source is guaranteed no matter how lamp stand 1 adjusts angle can guarantee that light fixture is to the constant functional requirement of desktop illumination.
The course of work of present embodiment is: code switch 6 cooperates with lamp stand 1 through driving sleeve 5; Make lamp stand 1 in adjusting angle; The knob 61 of stirring that can drive code switch 6 is rotated, thereby makes code switch 6 can export the different signals of telecommunication, and the signal of telecommunication of code switch 6 outputs is transferred to single-chip microcomputer; Thereby single-chip microcomputer is according to the electric current output of signal of telecommunication adjustment light source, to reach the effect of automatic change light-source brightness.
Present embodiment can be extended to following dimming function:
1, the functional relation of illumination adjusting
Functional relation is to realize the essential condition of the accuracy of present embodiment function, mainly is divided into two ATM layer relationsATMs:
The functional relation of the variation of the voltage signal of A, code switch output and the cognition of single-chip microcomputer, this ATM layer relationsATM can be divided the output signal of code switch according to the needs of practical adjustments brightness;
B, single-chip microcomputer be through understanding the signal of code switch, the functional relation of the output current of adjustment illumination light source, and this ATM layer relationsATM mainly curve of " brightness-electric current " through light source is confirmed.
2, realize fixedly illumination (that is: no matter how adjust by lamp stand; Light fixture desktop illumination can not change) principle: at first selected specific angle is worth as a reference; Confirm simultaneously under this angle light fixture to desktop brightness value (it is the desktop illumination of science that this brightness value is regarded as, and is decided to be D1);
A, when lamp stand is adjusted to less than fixed angle downwards, code switch can reduce single-chip microcomputer output signal, single-chip microcomputer can calculate the electric current output that generation meets the decline of functional relation accordingly, thereby guarantees that light fixture is constant to desktop illumination D1.
B, when lamp stand is adjusted upward to greater than fixed angle, code switch can rise to single-chip microcomputer output signal, single-chip microcomputer can calculate and produce the corresponding electric current output that meets the rising of functional relation, thereby guarantees that light fixture is constant to desktop illumination D1.
In order to realize the instantaneous illumination function that is returned to any needs, (also can be on the lamp stand 1) be provided with brilliance control button (figure is last not to be marked) on the base 7, and brilliance control button and pcb board electrically connect.The brightness value that these brilliance control buttons are controlled can be the desktop brightness value of using always, through triggering the brilliance control button, can make light fixture that desktop illumination moment is reached selected brightness value.The SCM program the inside is carried out the finite sequence ordering to the signal controlling and the brilliance control of code switch by key control, brilliance control is placed on the front of code switch signal controlling by the ordering of key control.
In addition; In the foregoing description; The effect of code switch 6 is to detect the rotational angle (being equivalent to detect the displacement of lamp stand 1) of lamp stand 1 and convert this rotational angle into the signal of telecommunication to be transferred to single-chip microcomputer and to understand; Driving sleeve 5 then is the function that is used to make code switch 6 and lamp stand 1 interlock, and in the above-described embodiments, code switch 6 has constituted displacement detector with driving sleeve 5.And displacement detector can also have other versions, for example, constitutes displacement detector with angular displacement sensor and driving lever and also can realize function with an automatic light meter.Moreover lamp stand and base also are not necessarily to articulate, and also can be other movable connection methods, and for example, the flexible connection, promptly lamp stand can slide with respect to base along its length direction.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to the technical scheme and the design of above description.
