Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lamp with a touch-type dimming device.

Conventionally, there have been various types of lamps in which the luminous flux value of the lamp body can be continuously changed by touching a part of the human body, such as a hand, to a metal support frame supporting the lamp body or a metal operating string. It had been devised.

However, these devices require a support frame that is larger than necessary to be touched by hand, or a separate operating string, so they are constrained in terms of form, have a complicated structure, and have a high current flow. Even if it is known that touching the flowing metal part is safe, it has the drawback of making the operator feel uneasy.

In view of the drawbacks of the conventional lamps mentioned above, the purpose of this invention is to provide a lamp with a simple structure, which does not cause any anxiety to the operator, and which is also aesthetically pleasing. In a lamp having a touch-type dimmer, a touch part having decorativeness such as a pattern, a figure, a design character, etc. made of a conductive material at an appropriate location on the surface of the dimmer of the lamp so as to be electrically conductive to the dimmer. The lamp is characterized by the following:

Hereinafter, the present invention will be described in detail with reference to the drawings.

Further, the touch portion 2 extends to the support portion 1a of the sea bream 1, and is maintained electrically conductive with the support base 3, which will be described later.

Reference numeral 3 denotes a support base made of a metallic material, and is provided with a fitting part 3a corresponding to the support part 1a of the above-mentioned Haya 1. The support part 1a of Haya 1 is inserted into the fitting part 3a, and the metal The locking screw 4 made of aluminum prevents the screw from being removed, and also ensures continuity between the touch section 2 and the support base 3.

Reference numeral 5 denotes a bottom plate of the support base 3, which is also made of a metallic material, and is locked to the support base 3 by locking means 6 such as screws.

7 is a sponge pad attached to the back side of the bottom plate 5, which serves both to prevent slipping and to insulate from the ground.

Reference numeral 8 denotes a lamp body, and reference numeral 9 denotes a socket. The socket 9 is fixed at a proper position within the support base 3 by welding, soldering, or other means on a support plate 10 that is attached in a conductive state with the support base 3.

Reference numeral 11 denotes an electronic circuit storage case made of an insulating material fixed on the bottom plate 5, in which an electronic circuit to be described later for adjusting the luminous flux of the lamp body 8 is housed, and the electronic circuit and the socket 9 are connected to each other. It is connected to the support base 3 via a connecting line 12 and via a contact plate 13 .

14 is a power cord. FIG. 3 is a circuit diagram showing an example of an electronic circuit for adjusting the luminous flux value of the lamp of the present invention, in which the same components as in FIGS. 1 and 2 are denoted by the same symbols.

That is, 8 is the lamp body, 15.16 is the capacitor,
17 is triac, 18 is choke coil, 19.2
0 is a resistor, 21 is a Zener diode, 22 is a diode, 23 is a transistor, 24 is an integrated circuit, 25 is a charging capacitor, 26 a and 26 b are AC voltage application terminals, and 27 is a ground terminal.

The capacitor 15 connected in parallel to the AC voltage application terminals 26 a and 26 b and the choke coil 18 connected in series to the triac 17 are for removing noise that invades the AC voltage. Capacitor 16, Zener diode 21. diode 22
is a power supply circuit for obtaining a DC voltage for driving the amplifier circuit and integrated circuit 24, which includes a transistor 23 and resistors 19 and 20.

Further, the AC voltage application terminals 26 a and 26 b are connected to a general commercial power source via the power cord 14 , and the ground terminal 27 is connected to the touch unit 2 via the contact plate 13 , support plate 10 , and support base 3 . be done.

When the integrated circuit 24 touches a part of the human body, for example, a hand, and the ground terminal 27 is grounded, the charging capacitor 2
It has the function of measuring the time that the hand is in contact with the touch part 2 by passing a weak current through the touch part 5 and measuring the charging voltage, thereby controlling the triac 17 and changing the conduction angle of the AC voltage.

The integrated circuit 24 performs different controls depending on the contact time.

In other words, when the time is less than 5Q m5ec, it is assumed that the charging capacitor 25 has been charged due to noise etc., and no control signal is output, and the time is 5Q m5ec~0.4.
When a time within the range of 0.4 sec is measured, a signal is output to the control signal line 24a to control the triac to make it conductive or non-conductive, and when a time of 0.4 sec or more is measured, the time is A signal for changing the conduction angle of the triac 17 according to time and causing a trigger is output.

The signal is also stored in a memory within the integrated circuit 24;
It will be read out during the next operation.

Next, the operation of the lamp will be explained.

First, when the lamp body 8 is off, that is, when the triac 17 is in a non-conducting state, touch the touch part 2 with your hand.
When touched for m5ec ~ 0.4 sec, the integrated circuit 24 turns on the triac 17 at each of the 0° and 180° phases of the applied AC voltage to make the triac 17 conductive.
A signal for triggering is output to the control signal line 24H.

Transistor 23 amplifies the above signal and converts it into triac 1.
7, the triac 17 becomes conductive over all phases of the supplied alternating current voltage, as shown by the shaded area in FIG. 4a, and the luminous flux of the lamp body 8 becomes maximum.

When the luminous flux of the lamp body 8 is at its maximum, the touch part 2 is pressed again.
When you touch for 50 m5ec to 0.4sec,
Integrated circuit 24 outputs a control signal for not triggering on any phase of the AC voltage applied to triac 17.

Therefore, no alternating current voltage is applied to the lamp body 8 over the phase range of 0 to 360 degrees, and its luminous flux becomes zero.

Thereafter, touch the touch part 2 with your hand for 50 m5ec -
Every time the lamp body 8 is touched for 0.4 seconds, the luminous flux of the lamp body 8 alternately repeats the maximum and zero states.

Next, when the luminous flux of the lamp body 8 is zero, the hand continues to be in contact with the touch part 2 for a while, and when the contact time exceeds 0.4 seconds, the integrated circuit 24 changes the triac 17 with a phase corresponding to the elapsed time. A signal for triggering is output to the control signal line 24a.

The conduction angles of 1 to 17 are as follows:
While touching the touch portion 2, the hand moves in the direction of the arrow as shown in FIG.

That is, the luminous flux of the lamp body 8 is small at first, then gradually increases, and is fixed when the touch part 2 is released.

Here, after the luminous flux of the lamp body 8 is fixed at a certain value, when the touch part 2 is touched again by hand for 5Q m5ec~Q, 4 seconds, the luminous flux value of the lamp body 8 becomes zero, and then again the touch part 2 When the light is turned off by hand for 5Q m5ec to 0.4sec, the light is turned on again to the above-mentioned fixed luminous flux value.

Further, after the luminous flux of the lamp body 8 is fixed at a certain value, when the touch section 2 is touched again for 0.4 seconds or more, the luminous flux gradually increases from the above luminous flux value.

Therefore, in the lamp of the present invention, the luminous flux value of the lamp body 8 can be freely changed by simply touching the touch part 2 provided on the lampshade 1.

In the above embodiment, the touch part 2 was coated with a colored conductive paint having translucent properties, but by adding a fluorescent substance to this, the touch part 2 can be easily recognized even in the dark. Alternatively, a conductive member such as silver paper or aluminum foil may be attached by an appropriate means.

Furthermore, the shape of the sheath 1 is not limited to one that completely covers the lamp body 8 as in the embodiment.

Furthermore, in the above embodiment, the support base 3 is used instead of the touch part 2.
Needless to say, the same light control as described above can be performed by touching the light with your hand.

The electronic circuit of the light control device is not limited to the embodiments, and any conventionally known and commercially available circuit may be used as long as it utilizes the earthing effect of the human body.

As described above, according to the present invention, in a lamp having a touch-type dimmer, a pattern, a figure, Since the touch part has decorative features such as design characters, there are no restrictions on the shape or size of the lamp, unlike in conventional cases where the support base of the lamp body or the operating string is used as the touch part. This has the advantage that there is no need to worry about touching a metal substance through which electricity is flowing, and the touch portion provides an aesthetically pleasing lamp.

In addition, the present invention has the disadvantage that the dimmer can be used without a separate switch for so-called recessed lamps, which have a support base for supporting the lamp body and the lamp inside the wall. are doing.
