[Background Art] In the past, there have been many stand-type lighting fixtures that can be dimmed; There have been problems such as inconvenience in controlling the light, especially when used on the floor.

[Purpose of the invention]

Therefore, an object of the present invention is to provide a stand-type lighting fixture that has good dimming operability and can provide uneven illumination.

[Disclosure of the Invention] The present invention comprises a sub-light control means for a lamp, and a sound generating means for emitting a sound when the dimming control means is operated, and the lamp and dimming control means are mounted on a cylindrical base with an opening on the top surface. It is equipped with electric parts such as a control means and a sound generation means, and is equipped with a touch means for operating the dimming control means made of an elastic body approximately in the center, and a cylindrical clove with light diffusing properties with an inner brim at the opening. It is characterized by having an inner flange protruding outside the base and being placed on the cylindrical base, which provides good dimming operability and allows for even illumination of the lighting fixture itself.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be explained based on the embodiments shown in FIGS. 1 to 6.

(1) is a cylindrical base with an opening on the top surface, and this cylindrical base t
In the center of the bottom of l+ is a socket (
3), and electrical components such as the above-mentioned dimming control circuit (4), electronic sound generation circuit (5j, connection circuit (61), etc.) are mounted around this socket (3). (7) is a globe made of milky white glass, and this globe (7) has a constriction capital (7a) at the lower end that is fitted into the corner wall (la) of the cylindrical base (11) so that it is adjacent to the constriction capital (7a). N (7)
b) into a cylindrical base (1) by protruding it outside the cylindrical ki & (IJ).
A touch sensor (8) (also referred to as an antenna) connected to the signal detection section of the dimming control circuit (4) is housed at the external apex of this globe (7). The touch sensor (8) is formed by winding a conductive wire into a coil shape, and is elastically deformed and restored when an external force is applied.The touch sensor (9)
8) and the touch type dimming control circuit (4). Further, 00) is a curl cord with a power plug derived from the cylindrical base (1).

Therefore, the light from the lamp (2) in the center of the cylindrical base (1) illuminates the globe (7) uniformly and evenly, so that the lamp image is uniform and there is no unevenness during dimming. 7) Among them! (7b) protrudes outside the cylindrical base (1), so the light from the lamp (2) diffused by the milky white globe (7) can evenly illuminate the outer surface of the cylindrical base (1). Beautiful lighting is possible. Incidentally, a conductive plate which also serves as support for the globe (7) may be used instead of the lead wire (9).

FIG. 3 shows a block diagram of a circuit according to an embodiment of the present invention. In the figure, (4) is a touch-type dimming control circuit, and this touch-type dimming control circuit (4) is a touch sensor for dimming operation ( When a finger etc. touches the lamp (2), a control circuit (not shown) including a phase control circuit that controls the lamp (2) is activated, and if the contact is for a short time, for example within 0.4 seconds, the lamp ( 2) Turn on or off, and if the contact is continuous, cyclically turn on the M
It repeats the light operation and is composed of a known touch dimming unit that maintains the dimming state even if there is no contact. (5) is an electronic sound generating unit. This electronic sound generation circuit (5) is composed of an appropriate known circuit that generates an electronic sound from a speaker (11) when an input signal is received. (6) is a touch-sensitive circuit. This is a connection circuit for inputting a detection signal from the dimming control circuit (41) which detects that a dimming operation is in progress to the electronic sound generation circuit (5) as the above-mentioned input signal.

Figure 4 shows a circuit diagram of the touch signal detection section in the touch dimming control circuit (4), where Ql is an oscillation transistor, Q2 and Q3 are detection signal generation transistors, L and C
1, 2, Cm, and C@ are an oscillation coil and a capacitor. In this circuit, when no human body is in contact with the touch sensor (8), the detection signal generation voltage 9V is output as is. In addition, when a human body such as a finger comes into contact with the touch sensor (8), the Q of the oscillation circuit changes and oscillation stops, and due to this stop, transistors Q2 and Q3 turn off and on, and the output terminal ■ and the ground terminal ■ During this period, a voltage equivalent to the voltage drop due to the resistor (for example, 2V) is generated. Figure 5 shows the relationship between the contact with the touch sensor (8) and the voltage between the output terminal ■ and the ground terminal 0. When there is no contact, a 9V "H" level signal is generated, and when there is contact, there is a 2V "H" level signal.
A 1L" level signal of v is output, and the period of the l L I level signal corresponds to the period of contact with the touch sensor (8). Furthermore, between the il! source input terminal ■ and the ground terminal ■ A voltage of DC 15V was applied.

Figure 6 shows a specific circuit of the connection circuit (6), in which σ and U are terminals connected to the terminals ■, ■, and ■ of the circuit in Figure 2, respectively, and signal input terminals ■. When is 'H' level, the transistor is also off and the photocoupler 0
The phototransistor QI+ of 2) is in an off state. On the other hand, when the input terminal is at "L" level, the base of transistor Q4 becomes 1 hour level and turns on, and current flows through the circuits of power supply input terminal C, light-emitting diode LED of photocoupler 02), transistor Q', and ground terminal door. i1 or flowing,
The phototransistor also turns on, and due to this turning on, the current i
2 flows, the transistor (6 turns on, and as a result of this turning on, the current i3 flows, the relay Ry operates, and the electronic sound generation circuit (power supply +9V is connected to the power supply 51) through the relay contact r of this relay Ry, and the electronic sound is generated. This causes the circuit (5) to operate.

When a finger or the like touches the touch sensor (8) for a short period of time (within 0.4 seconds), the short-time electronic sound generation circuit (5) is turned on and generates an electronic sound of, for example, "1 pitsu". At this time, the dimming control circuit (4) turns on or off the lamp (2) by inputting a short-time contact detection signal.

When the touch sensor (8+) is further touched with a finger or the like, the electronic sound generation circuit (5) continues to operate during that period, and the electronic sound continues to be emitted from the speaker (11).At this time, the dimming control The lamp Q) is cyclically illuminated by the function of the circuit (4), and when the touch sensor (8) is released from the touch sensor (8) at the appropriate timing, the current dimming state is changed. maintained.

At the same time, the electronic sound described above stops producing, indicating that the dimming operation has been completed. If it is desired to adjust the volume of the electronic sound, the resistance value of the variable resistor VR shown in FIG. 6 may be adjusted as appropriate. Furthermore, the tone color may also be changed.

[Effects of the Invention] As described above, according to the present invention, the touch means for operating the dimming control means made of an elastic body is provided approximately in the center of the glove, and an inner flange is provided at the opening of the glove, and the inner flange is made into a cylinder. The cylindrical base is covered with cloves that protrude outside the cylindrical base and have light-diffusing properties, and the lamp light diffused by the globe can evenly illuminate the outer surface of the cylindrical base, creating a beautiful illumination effect. The touch means can be easily operated, and since the touch means deforms and does not transmit external force to the glove or the cylindrical base, there is little risk of failure or damage.
