Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention particularly relates to indoor lighting devices such as desk lights and floor lights.

[Summary of the Invention] The present invention provides a lighting device such as a desk light, a floor light, etc., in which a motor driving means is provided in all or part of the movable parts provided for changing the illumination direction of a light source such as a fluorescent lamp. This allows the user to change the direction of illumination simply by operating the operation switch means.

[Conventional technology 1] Conventionally, desk lights installed on desks and floor lights for indoor use have been equipped with several rotatable movable parts on the main body or a flexible neck part, etc. There are devices that allow the lighting direction and lighting position of light sources such as lamps and light bulbs to be changed freely.

[Problems to be Solved by the Invention] However, all of the movable parts provided in these lighting devices are manually operated, which is inconvenient when adjusting the lighting direction.

For example, in the case of a desk light, it is difficult to adjust the lighting angle while sitting, and you often have to stand up a little and use both hands, so you can check the direction of the lighting while sitting. However, since it is not possible to make adjustments while changing the lighting conditions, it may be necessary to readjust the settings many times in order to obtain the best lighting conditions. Furthermore, there is a risk of accidentally touching a hot light source.

The same is true for floor lights; since you must go to the installation location and make adjustments, you cannot make adjustments while checking the lighting conditions, and there is also the risk that your hands may come into contact with the light source.

[Means for Solving the Problems] The present invention has been made in view of the above problems, and includes providing a motor drive means in all or part of the movable parts for changing the direction of illumination by the light source. The illumination device is configured such that the direction can be varied by operating switch means of the motor drive means.

[Function] By electrically driving the movable parts, the direction and position of the lighting can be adjusted using an operation switch.For example, a desk light can be adjusted with one hand while sitting, and is also compatible with a remote commander. Since i
Adjustment is also possible from the #I position.

Each of these movable parts 2a, 2b, and 2c is provided with a motor, and the above-mentioned rotational movement is performed by operating the switches 4a, 4b, and 4c. Note that 5 indicates a lighting switch.

The drive control block for the motors provided in the movable parts 2a, 2b, 2c is configured as shown in FIG. The signals are respectively sent to drive circuits 6a, 6b,
6c, and drive circuits 6a, 6b, and 6c supply drive power to motors 7a, 7b, and 7c, respectively, based on the operation signal. Note that the lighting t21ii may be used as the operating power source for the motors 7a, 7b, and 7c.

In this embodiment, the switch 4a has the above configuration.

By operating 4b and 4c, the direction of illumination by the fluorescent lamp unit 1 can be arbitrarily varied, and in other words, a desired illumination state can be set very easily just by operating the switches. Furthermore, since there is no need to directly operate the fluorescent lamp unit 1 or the heat-generating light source, there is no risk of accidentally touching the high-temperature light source.

In addition, the motors 7a, 7b are actually connected to the movable parts 2a, 2b, 2c via slip rings.

It is preferable to connect 7C so that it can be rotated manually.

is provided with an infrared light receiving section 13 and a command signal demodulating section 14, switches 15a to 15c, and a mote commander RC to enable remote control.

The control block is configured, for example, as shown in FIG.
The command signal generator 16 is activated by pressing the buttons a to 15c.
A predetermined command signal is generated from the infrared output section 17.
Sent from. The command signal outputted as an infrared ray is detected by the infrared receiving section 13 in the floor light main body 10 and converted into an electric signal, and is demodulated as an operation signal by the demodulating section 14, and is then demodulated by the driving circuits 18a to 18.
c. The drive circuits 18a to 18c supply drive power to the motors 19a to 19c in response to operation signals, and cause the lamp portion 11 to pan, tilt, and move up and down.

In this embodiment, since the illumination direction can be adjusted by remote control, it is easier to make adjustments while checking the illumination state.

Note that the remote control means is not limited to an infrared remote commander, but may also be a radio wave transmission method or a wired commander method. In addition, this kind of remote control method is the first
It can also be used in the desk light shown in the figure.

The control block is configured in this way, and ROM2
By the operation program of the CPU 26 held in 7,
In this embodiment, ■ electric operation of the movable parts 20 a to 20 c by operating the switches 23 a to 23 c, ■ electric operation of the movable parts 20 a to 20 c by remote control, ■ setting of an arbitrary lighting position and automatic adjustment to the set position. Operation,■
Automatic adjustment operation to the set position by timer reservation becomes possible. Each operation will be explained below.

First, the operation signals of the switches 23a to 23c are sent to the CPU 26.
, the CPU 26 inputs the corresponding drive circuit 2.
2a to 22c are controlled to drive motors 21a to 21c in the same manner as in the embodiment shown in FIG.

In addition, the movable parts 20a to 20 can be controlled by the remote commander.
When the operation c is operated, an operation signal similar to that of the switches 23a to 23c is input to the CPU 26 via the infrared light receiving section 24 and the demodulating section 25, and the CPU 26 operates the drive circuit 22.
A to 22c are controlled to drive motors 21a to 21c.

These controls operate as shown in Figures 1 and 3 above.
There is no difference from the embodiment shown in the figure.

Next, when the user sets an arbitrary lighting position and stores it in the RAM 28, and also operates the operation unit 32 to automatically drive each movable part to adjust to the set lighting position, the The person first operates each key of the setting section 31 while referring to the display screen 33 to set the movable sections 20a to 20a.
Data indicating the position of 20c is input to the CPU 26. C
PU26 is the input 3 for the movable parts 20a to 20c.
These numerical values are stored in the RAM 28 as setting data. R
For example, AM28 has five types of setting data in the first memory.
A storage area is prepared so that it can be stored as a fifth memory, and the user can decide in which area of the first memory to fifth memory the input setting data is stored in the setting section 31.
Specify arbitrarily by operating .

Further, the operation section 32 is provided with five keys corresponding to the first to fifth memories, and after the above setting operation is performed, the user can operate a predetermined key on the operation section 32 to The setting data corresponding to the key is read from the RAM 28, and the CPU 26 controls the drive circuits 22a to 22c based on the numerical values indicating the positions of the movable parts 20a to 20c that constitute the setting data to drive the motors 21a to 21c. is driven to operate the movable parts 20a to 20c in the set state.

At this time, the positions of the movable parts 20a to 20c are grasped by the position sensors 30a to 30c, and the CPU 26 performs control based on feedback information from the position sensors 30a to 30c, thereby storing the positions as setting data. The operating position of each of the movable parts 20a to 20c can be changed as the movement is made.

Note that the setting data may be stored in the ROM 27 or RAM 28 in advance as preset data. It is only necessary to operate one key of switches 23a to 23c.
Since it is no longer necessary to operate each of them individually, it becomes easier to adjust the illumination direction.

Finally, the automatic adjustment operation to the set position by timer reservation is performed by the user using the setting unit 31 to select one of the setting data stored in the first memory to fifth memory by selecting the reserved time and the above-mentioned setting operation. This is executed by specifying one and inputting it to the CPU 26.

That is, the CPU 26 associates the reserved time with the designated numerical value of the setting data and holds it in the RAM 2B, and starts a comparison operation between the reserved time and the time information by the timer 29,
When it is confirmed that the reserved time has been reached, the setting data specified in the reservation operation is read out, and the driving circuits 22a to 22c are controlled based on the setting data to change the illumination direction.

With this operation, for example, in the case of a desk light, you can set the lighting direction to be in all directions (different directions) after one hour, forcing a break from studying or reading, and letting the user know that it is time for a break. It will also be possible to enjoy a variety of lighting effects by periodically changing the lighting direction of the floor light.

As described above, in the embodiment shown in FIG. 5, by performing the lighting position control operation based on the setting data stored in the storage means, it is possible to more easily adjust the lighting position and change the lighting direction in various ways. can do.

In addition, in this embodiment, the ROM that stores the setting data
27. The RAM 28 may be installed on the remote commander side so that the setting data itself can be supplied to the main body side by infrared rays or wired.

By the way, in this embodiment, control by the CPU 26 has been explained as only positional control in the direction of illumination, but in addition to on/off control of illumination and, for example, in a dimmable lighting device, the amount of light can also be controlled in addition to the setting data. It is also conceivable that the adjustment and the on/off operation of the lighting are performed automatically by the operation unit 32 or automatically based on a timer reservation.

In each of the embodiments described above, a larger number of movable parts may be provided to enable more detailed control of the illumination direction.

[Effects of the Invention] As explained above, in the lighting device of the present invention, a motor driving means is provided in all or part of the movable part for changing the lighting direction, and the lighting direction can be changed by the operation switch means. This has the effect that the lighting direction can be adjusted very easily, and the adjustment can be made while checking the lighting condition, so there is no need to repeatedly make adjustments. Another advantage is that there is no danger of directly touching the high-temperature light source.
