Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device for dimming and lighting a lamp.

[0002]

2. Description of the Related Art Conventionally, there is an illuminating device for dimming and lighting a lamp for a light source having a structure shown in FIG.

This lighting device includes a dimmer 1 that outputs a dimming signal, and a dimming lighting fixture 2 that is dimmed and lit by a dimming signal from the dimmer 1. Utensil 2
Is provided with a dimming stabilizer 3 and a lamp 4 such as an incandescent lamp or a discharge lamp.

The dimmer 1 has an output level setting section 5 for setting an output level of a dimming signal, and one type of dimming signal format specified in advance according to an input from the output level setting section 5. And a control unit 6 for outputting the dimming signal through the dimming signal output unit 7. Further, the dimming stabilizer 3 includes a dimming signal input unit 8 for inputting a dimming signal from the dimmer 1,
A dimming circuit 9 converts a dimming signal input to the dimming signal input unit 8 into a lamp signal and outputs the lamp signal.

In the above configuration, the control unit 6 of the dimmer 1
Creates a dimming signal having the output level set by the output level setting unit 5 and outputs the dimming signal to the dimming signal output unit 7.
The light is output to the lighting device 2 for dimming. The dimming stabilizer 3 of the dimming lighting fixture 2 receives a dimming signal from the dimmer 1 and converts it into a lamp signal by a dimming circuit 9, and the lamp 4 is dimmed and lit by the lamp signal. .

Here, there are four types of dimming signal formats of dimming signals output from the dimmer 1, for example, as shown in FIGS. 11 (a) to 11 (d). That is, the dimming signal Sa in FIG. 3A has a frequency of 1 KHz and a voltage of 10 V PW.
An M signal that performs duty ratio control, a dimming signal Sb shown in FIG. 3B is a PWM signal having a frequency of 100 Hz and a voltage of 10 V, and a duty control is performed, and a dimming signal shown in FIG. The signal Sc is a PWM signal having a frequency of 1 KHz and a voltage of 12 V, which performs duty ratio control.
The output voltage of the dimming signal Sd in FIG.
Is controlled by a DC voltage.

[0007] Incidentally, which of the dimming signals Sa to Sd having such dimming signal formats is to be adopted is currently uniquely determined for each manufacturer. In other words, the manufacturer independently determines one dimming signal format from the four types of dimming signal formats, and controls the dimmer 1 to output a dimming signal having the determined one dimming signal format. I have to. Therefore, there is usually only one type of dimming signal format of the dimming signal output from the dimmer 1 of a certain manufacturer.

On the other hand, in the dimming stabilizer 3 incorporated in the dimming lighting fixture 2, the types of dimming signals that can be input (dimming signal format) are the same as those of the dimmer 1. It is determined for each manufacturer. In other words, which dimming signal format of the dimming stabilizer 3 can be input is determined by the manufacturer. In this case, usually only one type of dimming signal can be input.

Therefore, in order for the lighting device having the configuration shown in FIG. 10 to exhibit a predetermined function, the light control signal format of the light control signal output from the light control device 1 and the light control lighting device 2 must be controlled. The dimming signal format of the dimming signal that can be input to the dimming ballast 3 to be provided must always match the dimming signal format. It is common practice that both the light luminaire 2 and the dimmer 1 are of the same manufacturer.

[0010]

The degree of freedom was poor and it was extremely inconvenient. That is, if the dimmer 1 of a certain manufacturer has been introduced in advance to the dimmer lighting fixture 2 and the dimmer lighting fixture 2 needs to be replaced due to a failure or the like, the same is performed. Only the dimming lighting fixture 2 having the dimming stabilizer 3 of the manufacturer can be selected, so that the selection range of the dimming lighting fixture 2 is limited for the user.

[0011] Furthermore, in recent years, in the field of control of electric equipment, there is a demand for an open market, but it is difficult for the conventional structure as described above to sufficiently meet the demand for openness.

The dimming signal discriminating and converting section 14 includes an input circuit 15, two dimming signal detecting circuits 16, 17, a signal converting circuit 18, and an output circuit 19.

The input circuit 15 is formed of, for example, a transformer so as to maintain insulation from the dimmer 1 and to share the dimming signal Sx of the PWM signal and the analog signal.

One of the two dimming signal detecting circuits 16 and 17 converts one of the dimming signal detecting circuits 16 and 17 into a TTL level in order to detect the duty ratio of the input dimming signal Sx. The other light control signal detection circuit 17 performs A / D conversion to detect the voltage level of the light control signal Sx.

The signal conversion circuit 18 is constituted by a microprocessor or the like, and each of the dimming signal detection circuits 16 and 17
The dimming signal format of the dimming signal Sx from the dimmer 1 is determined based on the detection output of the dimming device 1 and the dimming signal Sx output from the dimmer 1 It is determined whether or not the dimming signal format is different from a preset dimming signal format. If the dimming signal format is different, the dimming signal Sx from the dimmer 1 is transmitted to the dimming stabilizer 3. The dimming signal format is converted so as to conform to the above. Therefore, the signal conversion circuit 18 stores information of a light control signal format suitable for the light control lighting fixture 2 in advance.

The output circuit 19 outputs the dimming signal converted by the signal conversion circuit 18 to the lighting fixture 2 for dimming.

Next, the operation of the dimming signal discriminating and converting unit 14 in the lighting device of the fourth embodiment will be described with reference to the flowchart shown in FIG.

The dimming signal Sx output from the dimmer 1 is
The light control signal is input to each of the light control signal detection circuits 16 and 17 via the input circuit 15 of the light control signal discriminating converter 14. One of the dimming signal detection circuits 16 converts the input dimming signal Sx to a TTL level for duty ratio detection, and the other dimming signal detection circuit 17 converts the dimming signal Sx to the voltage level of the dimming signal Sx. A / D conversion is performed for detection and output to the signal conversion circuit 18.

The signal conversion circuit 18 takes in the output of each of the dimming signal detection circuits 16 and 17 and determines the signal format and dimming level of the dimming signal Sx as follows, and determines the dimming illumination. The light is converted into a dimming signal conforming to the specifications of the device 2.

First, it is determined whether or not the voltage level of the input dimming signal Sx is 0 V (step 1). If the voltage level is 0 V, it is determined that the dimming signal Sx has not been input, and a default value (for example, 100%
A signal of a lighting output level is output (step 2).

If the voltage is not 0 V in step 1, it is determined that some dimming signal Sx has been input, and the value of the voltage level of the dimming signal Sx A / D converted by the dimming signal detection circuit 17 is determined. Is stored (step 3). Subsequently, the dimming signal Sx after the level conversion by the dimming signal detection circuit 16
It is determined whether or not an edge has been detected (step 4).

If no edge is detected in step 4, it is determined that the input dimming signal Sx is the analog dimming signal Sd shown in FIG. 2D (step 12).

On the other hand, if an edge is detected in step 4, the input dimming signal Sx is one of the dimming signals Sa to Sc in the PWM signal format shown in FIGS. 2 (a) to 2 (c). Then, the rising edge interval of the dimming signal Sx is measured (step 5). This corresponds to measuring the frequency of the PWM signal.

Next, the low level section of the input signal is measured (step 6). This corresponds to measuring the duty ratio of the PWM signal.

Then, it is determined whether or not the voltage level of the dimming signal Sx stored in the previous step 3 is equal to or higher than a predetermined level (step 7).

If the voltage level of the input dimming signal Sx is equal to or higher than a predetermined specified level, FIG.
It is determined that it is the dimming signal Sc shown in (c) (a dimming signal having a frequency of 1 KHz and a voltage level of 12 V) (step 11).

If it is determined in step 7 that the voltage level of the input dimming signal Sx is lower than a predetermined specified level, the dimming signal Sx is output as shown in FIG.
(A), the dimming signal S in the PWM signal format shown in (b)
a, Sb, so that the dimming signal Sx measured in the previous step 6 can be determined.
It is determined whether or not the low level section is 1 ms or less (step 8).

If the low-level section of the dimming signal Sx is 1 ms or less, the dimming signal Sx becomes the dimming signal Sa (the frequency is 1 kHz and the voltage level is 10 V) shown in FIG.
Is determined (step 9). On the other hand, when the low-level section of the dimming signal Sx exceeds 1 ms, the dimming signal Sx becomes the dimming signal Sb (frequency is 100 Hz and voltage level is 100 Hz) shown in FIG. 10
V dimming signal) (step 10).

Subsequently, when the signal conversion circuit 18 determines the signal format of the dimming signal Sx input as described above, the signal converting circuit 18 converts the dimming signal Sx into a dimming signal that matches the specification of the dimming stabilizer 2. A process for converting the signal into a signal Sa is performed (step 1).
3). For example, the dimming signal Sx output from the dimmer 1
Is a dimming signal Sa in the form of FIG.
