Description

Light modulator

The invention relates to a dimmer.

A dimmer for adjusting the dimming level of a lighting fixture has been proposed in, for example, Japanese Laid-Open Patent Publication No. 2001-150981 (hereinafter referred to as Document 1). The dimmer includes a rotary variable resistor, a dimming control circuit that generates a working signal based on the resistance value of the variable resistor, and outputs a dimming signal to the dimmer according to an operation signal from the dimming control circuit. Signal output circuit. In addition, the dimmer has a rotatable dimming knob attached to the variable resistor within a specified range. The resistance value of the variable resistor is adjusted by operating the dimming knob, and the dimming signal according to the resistance value is output to the dimmer. For example, when the dimming knob is turned to the rotation end point of the variable resistance to the minimum rotation end point, the dimming signal defining the dimming level is 0% is output to the dimmer, and the light source of the lighting fixture is used Dimming the signal and turning off the light.

In addition, the dimmer is also proposed, wherein the dimmer is configured to turn the lighting fixture on/off by a switch that is different from the dimming knob. In the dimmer, even if the dimming knob is turned to a rotational end point that becomes the minimum resistance value of the lighting fixture, the light source of the lighting fixture turns on the light at the minimum dimming level without turning off the light, and by utilizing The changeover switch is turned off to turn off the light.

The dimmer of Document 1 as described above is also useful for turning on/off the internal object of the micro switch of the lighting fixture in a mechanism for turning off the light by the dimming knob. In this case, the inching relationship is configured to be turned on/off by the projection of the dimming knob. Especially when the micro switch is turned to the "on" state, the light source of the lighting fixture turns off the light.

On the other hand, in the latter dimmer, since the switch for changing to the on/off state is distinguished from the dimming knob, the dimming knob has a different form (because there is no projection in the dimming knob). In addition, in the above two types of dimmers, the housings of these attached dimming knobs have different forms from each other because of the different forms of the dimming knobs. Therefore, in the production of the above two kinds of dimmers, it is necessary to prepare two kinds of metal molds for each dimming knob and the outer casing, and there is a problem that the production cost increases according to the above reasons.

The present invention has been made in view of the above problems, and it is proposed to realize a dimmer that reduces production cost by using a housing and a dimming control unit in common.

The dimmer of the present invention comprises: a rotary variable resistor, a dimming controller unit, a dimming operation unit, and a casing; wherein the dimming controller unit controls the dimming position of the lighting load according to the resistance value of the variable resistor The dimming operation portion is attached to the rotating shaft of the variable resistor and changes the resistance value of the variable resistor according to the rotating operation; wherein the outer casing is configured to cover at least the variable resistor and the dimming a controller unit; wherein a lever portion is configured to be in contact with an operation portion of a changeover switch that shifts an on/off state of the illumination load when the rotation axis is rotated to a designated position according to the rotation of the dimming operation portion, And closing the lighting load; wherein the stem portion is detachably formed along the rotating shaft.

In an embodiment of the invention, the rib is preferably disposed inside the shank so as to hit the bulge of the shank in a state where the shank is in contact with the changeover switch.

Embodiments of the dimmer of the present invention are illustrated by reference to the drawings.

Fig. 6 is a block diagram showing the dimmer A of the present embodiment. The dimmer A includes connection terminals T1 and T2, a full-wave rectifier DB1, a switching element Q1, a dimming controller unit 101, a zero-crossing detector unit 102, a dimming level setting unit 103, and a dimming bottom setting unit 104. The light emitting unit 105 and the memory unit 106 are connected to the external circuit by the connection terminals T1 and T2.

A series circuit including a commercial alternator 100 and a lighting load 200 such as an LED (Light Emitting Diode) bulb is an example of an external circuit. The series circuit is connected between the connection terminals T1 and T2. Further, the connection terminals T1 and T2 are respectively connected to the AC input terminals of the full-wave rectifier DB1.

The full-wave rectifier DB1 converts the AC voltage into a DC voltage by full-wave rectifying the AC voltage outputted from the connection terminals T1 and T2. The switching element Q1 is connected between the DC terminals of the full-wave rectifier DB1, and an example of the switching element Q1 is a thyristor (SCR).

The zero-crossing detector unit 102 detects the zero-crossing signal of the AC voltage by determining the level between the full-wave rectified voltage V1 and the specified threshold in the full-wave rectifier DB1. The signal level of the signal S1 output from the zero-crossing detector unit 102 is defined as a low level (L) when the voltage V1 is lower than the threshold, or as a high level when the voltage V1 is higher than the threshold (H) ).

The dimming level setting unit 103 is configured to set the dimming level of the illumination load 200, and the dimming level setting unit 103 includes a variable resistor 70 and a changeover switch 71, wherein the variable resistor 70 is configured to make the resistor The value is changed according to the rotational position of the operation portion (rotation shaft 70a), and the changeover switch 71 is configured to switch the on/off of the illumination load 200. When the user moves the operation portion to the closed position, the changeover switch 71 shifts from the off state to the on state, for example. And the dimming controller unit 101 switches the switching element Q1 to the non-conducting state and turns off the lighting load 200. Further, when the user moves the operation portion from the closed position to the intended rotational position, the changeover switch 71 shifts from the open state to the closed state, and the dimming controller unit 101 turns on the illumination load 200. Furthermore, the dimming controller unit 101 controls the power supplied to the lighting load 200 based on the resistance value of the variable resistor 70, and turns on the lighting load 200 in accordance with the dimming level of the rotational position.

Further, the switching element Q1 is configured to operate in an on state until the dimming controller unit 101 is subjected to the next zero crossing signal input. Therefore, since the phase angle of the voltage V2 supplied to the lighting load 200 is established when the power supply to the lighting load 200 is established, the lighting load 200 turns on the light by the set dimming level. Here, when the conduction phase angle is increased, the supply power to the illumination load 200 is increased, and the light output of the illumination load 200 is brightened. Further, this time indicates a period during which the switching element Q1 is turned on during the half cycle of the alternating current.

Further, the rod portion 6 has a roulette rod body 60 as shown in Figs. 5A and 5B, and the rod body 60 has a perforation 61 at the center. The perforation 61 is formed to be horizontal The cross section is formed into a semicircular shape, and the rotating shaft 70a of the variable resistor 70 is inserted into the through hole 61. Further, the front surface of the rod body 60 has a first convex portion 63 in which the convex portion 63 is formed in a triangular shape, and the convex portion 63 is formed to protrude to the front side. In this case, the front surface of the rod body 60 is shown as the upper surface in Fig. 5A. The back surface of the rod body 60 has a second convex portion 62 in which the convex portion 62 is formed to protrude to the rear side. In this case, the back surface of the rod body 60 is shown as the upper surface in Fig. 5B. The first end side of the rotation direction of the projection 62 has a slope 62a, wherein the slope 62a is disposed such that the degree of protrusion to the back surface is gradually reduced. When the inclined surface 62a comes into contact with the operation portion 71a of the changeover switch 71, the changeover switch 71 shifts to the open state. Further, the rod portion 6 is configured to be detachable in one direction of the rotating shaft 70a of the variable resistor 70. Like the dimmer A shown in Fig. 2A, the stem portion 6 is formed to be detachable if not necessary.

As shown in FIGS. 4A and 4B, the front body 10 constitutes the front portion of the outer casing 1, and the upper and lower surfaces of the front body 10 each have a recess 19. The grooves 19 are located in the left and right sides of the front end edges of the upper and lower surfaces of the front body 10. Further, the front surface of the front body 10 has a cylindrical projection, and the center of the cylindrical projection is provided with an opening portion 17a in which the opening portion 17a is formed in a circular shape. Further, a rotary handle (dimming operation portion) 34 is rotatably attached to cover the projection 17. The rotary handle 34 is formed like a dish, and the rotary handle 34 is configured to be coupled to the rotary shaft 70a of the variable resistor 70.

The back surface of the projection 17 of the precursor 10 has a rib 17b in which the rib 17b is formed to protrude to the rear side (see Fig. 4B). When the rotary handle 34 is rotated and moved to the closed position, the projection 63 of the lever portion 6 becomes hit by the rib 17b (see Fig. 3A). Here, the rotation direction of the rotary handle 34 is taken as an example in the counterclockwise direction. In this case, since the projection 62 of the lever portion 6 comes into contact with the operation portion 71a of the changeover switch 71, the changeover switch 71 is shifted to the "on" state. Therefore, the lighting load 200 becomes a closed light.

The rear body 11 constitutes the back of the outer casing 1, and the rear surface of the rear body 11 is open and has a threading hole and a tool insertion hole (not shown). The threading hole is configured to allow the wire to be inserted into the outer casing 1, and the tool insertion hole is disposed near the threading hole. In this case, the number of the threading holes and the tool sockets are preferably two threading holes and two tool sockets, respectively. Further, the inside of the casing 1 is covered with a quick connectable terminal device (not shown), and the quick connectable terminal device is configured to be connected to a wire inserted from each of the threading holes.

Further, when the chain spring of the quick connectable terminal device is pressed in the direction in which the chain spring is separated from the wire from the top of the tool into which the tool jack is inserted, the wire can be easily separated from the quick connectable terminal device. Further, since the quick connectable terminal device is well known, its detailed description is omitted.

Further, the cover member 3 is detachably attached to the front surface of the outer casing 1. The cover member 3 is formed in the shape of a square plate. In this case, the cover member 3 is preferably formed of a synthetic resin. The cover member 3 has an open circular hole 31 at the center of the cover member 3 so as to pass the rotary handle 34.

The back surface of the cover member 3 has a plurality of stopper pieces, and the stopper sheets are formed to protrude from the positions of the corresponding upper and lower side surfaces to the rear side (not shown). When the stopper piece and the groove 19 are latched together to support each other, the cover member 3 is then attached to the outer casing 1. Further, an indicator indicating the range of rotation of the rotary handle 34 is provided on the front surface of the cover member 3 by a process such as printing. As shown in FIG. 2A, the smaller dot D1 represents the bottom position of the dimming range, and the larger dot D2 represents the maximum position of the dimming range. A similar arc L1 connecting the dots D1 and D2 represents the rotatable range of the rotary handle 34. Further, a symbol indicating "OFF" of the closed position of the power switch is set to the right of the smaller dot D1. On the other hand, the symbol of "switch off" is preferably indicated below the smaller dot D1.

Further, the front body constitutes the front portion of the outer casing 1, and the right side surface of the front body 10 has a stopper hook 14 (see Fig. 4A).

The side panels 21 are preferably formed on the right side of the attachment frame 2, and the stop hooks 14 are preferably arranged as a set of stop hooks 14, The two sets of stop hooks 14 are preferably disposed on the left side surface of the front body 10, and the two sets of stop hooks 14 are preferably formed to be aligned in the up and down direction. Furthermore, the aforementioned set of stop hooks 14 consist, for example, of two stop hooks 14. In this case, since the stopper hook 14 is latched with the hole 23 of the corresponding stopper hook 14, the outer casing 1 is attached to the attachment frame 2. In this state, the entire front surface of the outer casing 1 protrudes from the window 20 of the attachment frame 2 to the front side. Further, in the right side surface of the front body 10, the slit 15 of the rear end side opening is provided on the upper and lower sides of the portion having the stopper hook 14 (see FIG. 4A), and is positioned between the pair of slits 15. The protruding piece 16 becomes elastic in the left-right direction. When the projection piece 16 is bent inward by pressing the projection 16a provided at the rear end portion of the projection piece 16, the stopper hook 14 becomes separated from the hole 23. Therefore, the outer casing 1 can be separated from the attachment frame 2. Further, an elongated hole 25 is provided at the frame side 22 of the attachment frame 2 to fix the attachment frame 2 to the surface of the building by screws. Further, the upper and lower frame sides 22 have hook holes 26 and round holes 27. The hook holes 26 are configured to hook a metal tool (not shown). The metal tool is used to fix the attachment frame 2 to a building material such as a sheet. The circular hole 27 is configured to pass a screw through the attachment frame 2, wherein the screw is used to directly attach the attachment frame 2 to the building material. Therefore, the attachment frame 2 can be attached to the surface of the building by the above attachment method, wherein the method can be easily selected depending on the attachment position of the construction surface. Further, when the frame (not shown) provided in a square shape and attached to the front is attached, the screw holes 24 provided at the upper and lower frame edges 22 are used.

In this case, the outer casing 1 having the dual module size is attached to the attachment frame 2. When the notch of the outer casing 1 is formed, the closure member 4 is attached to the pallet to cover the notch because the aperture of the pallet is not completely covered (see Fig. 2A).

The dimmer of this embodiment has the structure described above and is implemented on the surface of the building as follows. The contractor brings the outer casing 1 to the vicinity of the attachment frame 2 from the back side of the attachment frame 2, and fixes the respective hooks 14 on the left and right sides of the outer casing 1 to the side sheets 21 provided on the attachment frame 2, respectively. Hole 23 And the contractor then pulls the wire (not shown) provided on the back side of the building surface from the attachment hole (not shown) provided on the surface of the building to the front surface of the building surface. The wire that removes the top cover is inserted into the threading hole and connected to the quick connectable terminal device. The contractor accommodates the excess wires connected to the dimmer A in the attachment holes, and fixes the frame to the surface of the building in a state where the back of the casing 1 is provided in the attachment hole. Further, when the contractor fixes the stopper piece (not shown) of the cover member 3 to the recess 19 of the front body 10, the cover member 3 becomes attached to the front surface of the outer casing 1. Therefore, the frame (not shown) and the decorative panel (not shown) are attached to the attachment frame 2 On the front side, the work of attaching the dimmer A is completed.

In the state where the construction is completed, since the front surface of the outer casing 1 is covered by the cover member 3, the button 73a constituting the push button switch 73 of the dimming bottom setting unit 104 is configured to be uncontrolled by the contractor. Further, the rotary handle 34 and the cover 33 are exposed from the circular hole 31 and the long hole 32 of the cover member 3, respectively. Therefore, even if the cover member 3 is attached to the outer casing 1, the rotary handle 34 can be controlled, and the radiation of the light-emitting portion 105 becomes perceptible through the lamp cover 33.

When the user rotates the rotary handle 34 in the counterclockwise direction and moves the groove 34a to the "OFF" position, the operation portion 71a of the changeover switch 71 is pressed by the projection 62 of the lever portion 6, and the changeover switch 71 is shifted from the closed state to the closed state. Open state. In this case, the projection 63 of the stem portion 6 becomes the rib 17b that hits the front body 10 (see Fig. 3A), and the force applied to rotate the rotary handle starts to become large. Therefore, the user can perceive that the changeover switch 71 is shifted to the on state. The dimming controller unit 101 shifts and continuously maintains the switching element Q1 to the on state, and turns off the power supply to the lighting load 200. Therefore, the lighting load 200 becomes a closed light.

Further, when the user rotates the rotary handle 34 in the clockwise rotation direction and moves the groove 34a to the designated position between the dots D1 and D2, the projection 62 of the lever portion 6 collides with the operation portion 71a of the changeover switch 71. The touch state is aroused, and the changeover switch 71 is shifted from the on state to the off state. In this case, the dimming controller unit 101 turns on the lighting load 200 while dimming the controller unit 101 to dim and turn on the lighting load 200 according to the dimming level of the rotational position of the rotating handle 34. For example, the dimming controller unit 101 applies a fixed voltage to a series circuit composed of a variable resistor 70 and a fixed resistor, and detects voltages on both sides of the variable resistor 70. Therefore, the resistance value of the variable resistor 70 becomes detected. Further, the dimming controller unit 101 turns on the switching element Q1 when the time from the high level inversion to the low level of the output signal S1 of the zero-crossing detector unit 102 passes the time according to the rotational position of the rotary handle 34. Here, the rotational position of the rotary handle 34 means another name such as the resistance value of the variable resistor 70. Then, the dimming controller unit 101 keeps the switching element Q1 in the "on" state until the zero-crossing signal of the alternating current is detected, and the conduction phase angle of the switching element Q1 is determined according to the rotational position of the rotary handle 34. Therefore, the lighting load 200 is dimmed.

In addition, FIG. 2A shows a front view of another example of the dimmer A. In the dimmer A of FIG. 2A, since the rotary handle 34 is rotated past the "OFF" position, the illumination can be turned off. Load 200. Further, in the dimmer A of FIG. 2B, the lighting load 200 can be turned off by the switching means 5 for turning on/off the light different from the rotating handle 34. Further, in the dimmer A of FIG. 2A, the changeover switch 71 and the transfer changeover switch 71 are provided to the lever portion 6 in the open/closed state. However, in the dimmer A of Fig. 2B, the above-described changeover switch 71 and the stem portion 6 are not required. Here, the components other than the above-described changeover switch 71 and the lever portion 6 are the same as those of the dimmer of FIG. 2A. Therefore, the same reference numerals will be given to the components of the dimmer described above, and the detailed description will be omitted.

The dimmer mainly includes a casing 1 and a cover member 3, wherein the casing 1 encloses the substrates 7 and 9 inside, and the cover member 3 is attached to the casing 1 to cover the front surface of the casing 1. The outer casing 1 is formed to have a dual module size. The outer casing 1 is attached to the two attachment positions on the upper side of the attachment frame 2, and the switching device 5 is formed to have a single module size. The switching device 5 has a lever 50 in which the lever 50 is disposed on the front side of the switching device 5, and the lever 50 is formed as a square plate. The lever 50 is formed to be fixed to the first end side in the width direction, and to be movable in the front-rear direction in the second end side in the width direction. When the lever is controlled by pressing in the front-rear direction, the switching device 5 shifts to the on/off state. The switching device 5 has a light-emitting portion 51 in which the light-emitting portion 51 is formed to indicate an operation state of the switching device 5, and the light-emitting portion 51 is disposed at a position on the left side of the switching device 5. For example, when the switching device 5 shifts to the "on" state, the light-emitting portion 51 is turned off. Further, when the switching device 5 is shifted to the off state, the light emitting portion 51 is turned on. Therefore, since the light-emitting state of the light-emitting portion 51 becomes perceived, the operational state of the switching device 5 can be understood, and the position of the switching device 5 can be found by the light of the light-emitting portion 51 when the light is turned off at night. Here, the light-emitting state of the light-emitting portion 51 indicates a state in which the light-emitting portion 51 is turned on or off, and the operation state of the switching device 5 indicates a state in which the switching device 5 is in operation or not.

Except that the illumination load 200 is transferred to the on/off state by the pressing control of the control handle 50, since the operation of the dimmer A is mostly similar to the dimmer of FIG. 2A, the dimming in this embodiment is omitted. A detailed description of the operation of Device A.

Like the dimmer A of FIG. 2A, when the illumination load 200 is closed by the rotary handle 34, the lever portion 6 is attached to the rotary shaft 70a of the variable resistor 70. Further, the changeover switch 71 can be set and applied such that the open/close state is transferred by the lever portion 6. Further, as with the dimmer A of FIG. 2B, when the illumination load 200 is turned off by the switching device 5, the lever portion 6 and the changeover switch 71 are not required. Furthermore, the rotary handle 34 and the outer casing 1 to which the rotary handle 34 is attached can be shared. specific In this case, a mold is prepared for each of the rotary handle 34 and the outer casing 1. Therefore, the manufacturing cost can be reduced as compared with the case of preparing the mold corresponding to each part.

In the present embodiment, the rib 17b is provided on the front body 10 of the outer casing 1 so that the convex portion 63 of the rod portion 6 hits the rib portion 17b. However, if the inside of the outer casing 1 has ribs, the ribs may be provided in the rear body. Therefore, the present invention should not be limited to the description of the embodiment.
