Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a lighting fixture with a delayed light-off function.

[0002]

[Prior art]

 FIG. 5 is a sectional view showing a conventional luminaire disclosed in, for example, Japanese Utility Model Publication No. 62-30800, in which 1 is a transmitter, 2 is a main light source, 3 is a receiver having a control circuit built in, and 4 Is a miniature ball that serves as an auxiliary light source when the light is delayed. In the illumination device thus configured, every time the receiver 3 receives the signal from the transmitter 1, the control circuit turns on the main light source 2, and the main light source 2 is not turned on so that the bean ball 4 is predetermined. The operation of turning on the light for a certain time and then extinguishing the light is repeated.

[0003]

[Problems to be solved by the device]

 Since the conventional lighting equipment is configured as described above, the delayed light-off function is convenient when going out at night, and the delayed light-off operation mode changes the lighting light source from the main light source 2 to the miniature ball 4. It has the advantage that it can be easily understood, but it must have two types of light sources: the main light source 2 and the miniature ball 4 as an auxiliary light source in the delayed light-off mode, which requires a large number of parts and complicates the structure. Conventionally, the miniature ball 4 having a small w of about 5 w is generally used, and the main light source 2 is generally 60 w or more. However, since the brightness difference from the main light source 2 is large, the main light source 2 is large. There was a problem that when switching from 2 to miniature balls 4, it was difficult for the eyes to adapt and the eyesight was temporarily reduced, making it difficult to see.

The present invention has been made to solve the above-mentioned problems, and it is easy to understand that the delayed light-off mode has been entered due to the difference in light and dark, and the number of parts is small. It is an object of the present invention to provide a luminaire which is safe from the viewpoint that the eyes can easily adjust to the brightness when entering the delayed light-off mode.

[0005]

Means for Solving the Problems A lighting device according to the present invention is configured such that, after receiving a turn-off instruction, a main control light source is turned on for a predetermined time and then turned off, and a main light source is turned on for a predetermined time during the predetermined time. It is equipped with a dimming circuit that adjusts the dimming rate. Further, in this invention, the main light source is an incandescent lamp and the dimming ratio is set between 20% and 60% (power ratio).

[0006]

[Action]

 In the lighting apparatus according to this invention, when the light-off instruction is received, the light source is turned on for a predetermined time and then turned off, so that a constant brightness can be maintained at night or until leaving the room. In addition, when the light-off instruction is received, the main light source enters the dimming state, so it is easy to understand that the delayed light-off mode has been entered without switching to another light source such as miniature balls.

Furthermore, by using an incandescent lamp as the main light source and setting the dimming ratio to 20% to 60%, dimming can be easily performed, and at the same time, a small w, such as a bean ball, can be lit. In comparison, the difference in brightness between when all lights are on and in the delayed turn-off mode is small, and the eye easily adapts when entering the delayed turn-off mode.

[0008]

【Example】

 Example 1. An embodiment of the present invention will be described below with reference to the drawings. 1 and 2 and 3, 11 is a transmitter for transmitting infrared signals, 12 is a main light source consisting of a 60w incandescent lamp, and 13 is a control circuit for blinking the main light source 12 by the signal of the transmitter 11. Then, after receiving a turn-off instruction from the transmitter 11, the delay lighting circuit 15 that turns on and turns off the main light source 12 for a predetermined time and the dimming circuit 16 that dims the main light source 12 at a predetermined dimming rate for the above-mentioned predetermined time. Have. Reference numerals 15a and 15b are signal lines connected between the delay light-off circuit 15 and the dimming circuit 16. Reference numeral 15a is a lighting control signal, and 15b is a dimming control signal. When the lighting control signal 15a is at "H" level and the dimming control signal 15b is at "L" level, the dimming circuit 16 lights the main light source 12 all the way. When both the lighting control signal 15a and the dimming control signal 15b are at "H" level, the dimming circuit 16 dimms and lights the main light source 12. When both the lighting control signal 15a and the dimming control signal 15b are at "L" level, the dimming circuit 16 turns off the main light source 12. When the transmitter 11 generates a signal for instructing extinction, the delay extinction circuit sets the lighting control signal 15a and the dimming control signal 15b to "L" level after maintaining the "H" level for the predetermined time. Therefore, the dimming circuit 16 dims the main light source 12 for a predetermined period of time after the transmitter 11 generates a signal to turn off the light, and then turns off the light. FIG. 3 shows an explanatory diagram of these signals. The above-mentioned fixed time is about 10 seconds as the time required to leave the room after instructing to turn off the light, and the dimming ratio is about 40% (power ratio) in consideration of the adaptation of the eye when switching from the full-light state. Is set to.

The operation of the lighting device configured as described above will be described. When going out of the room with the main light source 12 turned on at night, if the transmitter 11 gives an instruction to turn off the light in the room, the main light source 12 will be in a dimming state with a power ratio of about 40%, and the miniature ball It is clear that the instruction to turn off the light was received even if there was no auxiliary light source such as. Then, since the main light source 12 is continuously turned on for about 10 seconds, the feet are bright until it goes out of the room. Further, since the dimming ratio is about 40%, it is not extremely dark like a miniature ball of about 5w, the eyes are easily adapted when entering the dimming state, and the temporary deterioration of visual acuity is small. Regarding the adaptability of the eye to the brightness, it is described as follows in the guide for indoor lighting (published by Denki Shoin Co., Ltd. on May 15, 1978). The process of adjusting the sensitivity level according to the brightness of the eyes, or the state in which the sensitivity level is adapted to the brightness, is called adaptation to the brightness.First of all, the pupil is made larger or smaller. , Adjust the amount of light entering the eyes. The retina is equipped with a weak light receiver (rod) and a strong light receiver (cone). Each of the light receivers is adjusted to change the amount of the chemical substance therein in response to the change of the light intensity level, and is adjusted to be suitable for the light intensity level at that time. The change of light adaptation from dark level to light level (actually a continuous change) is done by decomposing and reducing the photochemicals in the receiver, so that it is adjusted in a relatively short time (1-2 minutes). However, the dark adaptation from bright to dark takes a considerable amount of time because new substances must be made. It takes more than 30 minutes to complete the adjustment when the outdoor brightness is suddenly changed to darkness. Therefore, as described above, it can be said that the embodiment of the present invention can reduce the difference in brightness and darkness and is easier for the eye to adapt as compared with the miniature ball.

Example 2. FIG. 4 shows another embodiment of the present invention. Since the main light source 12 is composed of two types of light sources, 12a is a 60w incandescent light bulb, and 12b is a 32w and 40w ring fluorescent lamp. Reference numeral 17 is a lighting circuit of the fluorescent lamp 12b. The illumination state by the main light source 12 is not single, and only the fluorescent lamp 12b is turned on, only the incandescent lamp 12a is turned on, and the mixed lighting of the fluorescent lamp 12b and the incandescent lamp 12a is selected according to the preference of the transmitter 11. it can. In any state, when the transmitter 11 gives an instruction to turn off the light, the incandescent light bulb 12a is turned on at the dimming rate of about 40% (power ratio) for about 10 seconds and turned off. Similar to the embodiment shown in FIGS. 1 and 2, it is clearly understood that the turn-off instruction has been received, and the feet can be kept bright until the person goes out of the room. Good adaptability. In the above embodiment, the dimming rate of the incandescent light bulb in the delayed light-off state is set to about 40% in terms of power ratio, but the present invention is not limited to this, and if it is in the range of 20 to 60%, the same effect as above is obtained. Further, the incandescent light bulb can easily perform wide-range dimming in the range of 0 to 100%, and the dimming degree may be arbitrarily set. Furthermore, if it has an arbitrary continuous dimming function, the incandescent light bulb can be used as a night light in addition to the delayed light-off.

[0011]

[Effect of device]

 As described above, according to the present invention, since the delay light-off circuit and the dimming circuit are provided so that the main light source is turned on after being lit for a predetermined time in the dimming state, it is easy to understand that the delayed light-off mode has been entered. The number of parts is small, and the visual acuity is unlikely to deteriorate when the delayed light-off mode is entered.

[0006]

[Action]

The control means of the luminaire with the delayed light-off function configured as described above receives a lighting command. The light source body is normally energized by means of a light-off command, and the light source body is actuated by a light control means and a time-de-energizing means in response to a turn-off command. Then, the light source body is dimmed and turned off after a predetermined time period. Also, The light source reduces the light source to 20% to 60% of the normal illumination.

[0007]

【Example】

Example 1. 1 to 3 are views showing an embodiment of the present invention, in which the same reference numerals as those in FIG. 5 designate corresponding parts, 1a is a signal from a transmitter 1, and 2 is a light source comprising an incandescent lamp of 60W. The body 5 is a dimming device for dimming that emits the signal 5a, and the dimming rate is set to about 40%. 6 is a deenergizing means for emitting a signal 6a, which is set to operate after a predetermined time period of about 10 seconds. 7 is a control means for the light source 2 and normally biased by lighting instruction of the transmitter 1, to urge the light source body 2 through a more light control means 5 and deactivated means 6 Off command.

[0008] In the luminaire with the delayed light-off function configured as described above, the signal 1a When the lighting command is issued, the signal 5a becomes L level and the signal 6a becomes H level. Therefore, the light source body 2 is normally energized by the control means 7 and all lights are turned on. And signal 1 When the turn-off command is issued by a, both signals 5a and 6a become H level. The light source body 2 is energized and dimmed by the control means 7, and a predetermined time After a lapse of time, both the signal 5a and the signal 6a become L level, and the light source body 2 is deenergized and turned off. Light up.

Accordingly, at night, when leaving the room in a state in which the light source 2 are lit, issues a result off command to Shin machine 1 feed in a room, the light source body 2 is dimmed to about 40% power ratio. With this, it is possible to confirm the light-off announcement. Further, since the dimming lighting of the light source body 2 is continued for about 10 seconds after the start of dimming, it is possible to safely exit because the feet are bright enough to easily adapt to the eyes until it goes out to the outdoor area . Further, the miniature ball shown in FIG. 5 is not required, and the device configuration can be simplified and the manufacturing cost can be reduced.

[0010] It should be noted that, for the adaptation of the eye to the brightness, has been described as follows in the indoor lighting of guide (1978 May 15, issued Co., Ltd. electrical Shoin issue). The process of adjusting the sensitivity level according to the brightness of the eyes, or the state in which the sensitivity level is adapted to the brightness, is called adaptation to the brightness.First of all, the pupil is made larger or smaller. , Adjust the amount of light entering the eyes. The retina is equipped with a weak light receiver (rod) and a strong light receiver (cone). Each of the light receivers is adjusted to change the amount of the chemical substance therein in response to the change of the light intensity level, and is adjusted to be suitable for the light intensity level at that time. Switching from dark to bright levels of light adaptation (actually a continuous change) is done by decomposing and reducing the photochemicals in the receiver, so adjust for a relatively short time (1-2 minutes). However, the dark adaptation from bright to dark takes a considerable amount of time because new substances must be made. It takes more than 30 minutes to complete the adjustment when the outdoor brightness is suddenly changed to darkness. Therefore, as described above, it can be said that the embodiment of the present invention can reduce the difference in brightness and darkness and is easier for the eye to adapt as compared with the miniature ball.

[0011] Example 2. FIG. 4 is a view showing another embodiment of the present invention , in which the same reference numerals as those in FIGS. 1 to 3 designate corresponding parts , 2 is a first-type light source body composed of an incandescent lamp, and 21 is a fluorescent lamp. It is a type 2 light source .

Namely, the lighting of only the first kind light source body 2 by a command from a transmitter 1, the lighting of only the second type light source 21, also the first type, mixed lighting of the two light source 2 and 21 prefer Can be selected according to. In either state, the one light source 2 of the dimming If there is OFF command from the transmitter 1, Off, Off of the two light source 21 is made, the implementation of Figures 1-3 Obviously, the same effect as the example can be obtained.

In the above embodiment, the dimming rate of the incandescent light bulb in the delayed light-off state is set to about 40% in terms of power ratio, but the invention is not limited to this. Have. Further, an incandescent light bulb can easily perform wide-range dimming in the range of 0% to 100%, and the dimming degree may be arbitrarily set. Furthermore, if it has an arbitrary continuous dimming function, an incandescent light bulb can be used as a night light in addition to the delayed lighting.

[0014]

[Effect of device]

This invention is more normal use of the light source to the light control means, as described, set the de-energization means only during lighting command by the control means is total light lit normally urge the light source, thus the off command The light source body is dimmed and turned on through the dimming means and the deenergizing means, and is turned off after a predetermined time period . Thus, the auxiliary light source is a required cheap to manufacture can simply constructed, also it has the effect you increase the difference less safety brightness in dimming.
