Description

  The present invention relates to a luminaire that uses a plurality of discharge lamps as light sources and can switch the total light output of each of the discharge lamps in at least three stages.

  2. Description of the Related Art Conventionally, there is provided a lighting fixture that includes a plurality of annular discharge lamps and a lighting device that supplies lighting power to the discharge lamp, and the plurality of discharge lamps and the lighting device are housed in a fixture body. Japanese Laid-Open Patent Publication No. 2000-188196 is known as a lighting fixture that performs dimming control as a whole lighting fixture by turning off or dimming a book discharge lamp.

  In this invention, a double-tube type having an electrode at one end, a closed portion at the other end, and the vicinity of the closed portion joined by a bridge joint, and a single discharge path formed inside. In lighting fixtures that use ring-shaped fluorescent lamps (in this case, Matsushita Electric Industrial Twin Parook) 40, 70, and 100 as the light source, each discharge lamp is turned off or turned on with an output of 60% or less of the total lighting. As a result, the temperature inside the lighting fixture is reduced, and the luminous efficiency of the discharge lamp is improved. In addition, it is possible to obtain a wide range of illuminance from low illuminance to high illuminance according to the user's preference.

  Among the lighting fixtures according to the present invention, FIG. 7 shows a configuration in which two double-tube annular fluorescent lamps of 40 and 100 are used as a light source. This luminaire is composed of an AC power source Vs, a 40-type double tube-type ring-shaped fluorescent lamp 3, a 100-type double-tube-type ring-type fluorescent lamp 4, and the output voltage of the AC power source Vs. 40-type double-stage output supplied to each of the 40-type double tube-type ring-shaped fluorescent lamp 3 and the 100-type double-tube-type ring-shaped fluorescent lamp 4 after being converted to a high-frequency voltage (about 40 kHz to about 100 kHz) by turning off. Type lighting device 9a, 100-type two-stage output type lighting device 10a, and switching means 2a for switching the outputs of 40-type double-tube-type annular fluorescent lamp 3 and 100-type double-tube-type annular fluorescent lamp 4; Consists of

  The switching means 2a is configured to switch the light output of the 40-type double tube-type annular fluorescent lamp 3 and the 100-type double-tube-type annular fluorescent lamp 4 to a fully lit state (substantially lamp rated light output, hereinafter referred to as FULL). ) Called a lighting mode), a dimming state (approximately 50 to 70% light output of the rated lamp light output, hereinafter referred to as a dimming lighting mode), and a light-off state. . The schematic diagram of the lighting state of the lighting fixture obtained by this structure is shown in FIG. In FIG. 8, double diagonal lines indicate the full lighting mode, diagonal lines indicate the dimming lighting mode, and no diagonal lines indicate the extinguishing mode.

  FIG. 8 is a table of lighting modes (a) to (i) of the lighting modes of the 40-type double tube-shaped annular fluorescent lamp 3 and the 100-type double-tube-shaped annular fluorescent lamp 4. Is shown in Table 1. In the table, FULL output means full lighting mode, and DIM output means dimming lighting mode. FIG. 8 and Table 1 are combinations of lighting states of the 40-type double-tube-type ring-shaped fluorescent lamp 3 and the 100-type double-tube-type ring-type fluorescent lamp 4, and each has nine illuminances. There are different lighting states, and FIG. 9 shows the illuminance level in each lighting state as a dimming ratio.

  The graph of FIG. 9 shows that the dimming ratio is 100% when both the 40-type double-tube annular fluorescent lamp 3 and the 100-type double-tube annular fluorescent lamp 4 are lit in the full lighting mode. As shown in a bar graph. The light output of each lamp in the dimming lighting mode is represented as 50% of the full lighting mode in this graph. The bar graph also shows the breakdown of the 40-type double-tube annular fluorescent lamp 3 and the 100-type double-tube annular fluorescent lamp 4 for the total light output.

According to FIGS. 8, 9 and Table 1, the full-lighting mode, the dimming lighting mode, and the 40-type double-tube annular fluorescent lamp 3, and the 100-type double-tube annular fluorescent lamp 4, respectively, It can be seen that eight levels of illuminance can be obtained substantially continuously according to the user's preference, except for the all extinguished state, by individually controlling and combining the three extinguished states.
JP 2000-188196 A

  However, in the above conventional example, the following problems occur. For example, in FIG. 9, when considering the switching operation from the lighting state (h) at the 6th stage to the lighting state (c) at the 7th stage among the 8 stages counted from the higher illuminance, It is necessary to perform a two-step operation in which the double-tube-type ring-shaped fluorescent lamp 3 is started from the light-off mode and turned on in the full lighting mode, and the 100-type double-tube-type ring-shaped fluorescent lamp 4 is turned off from the dimming lighting mode. Therefore, the operation is complicated.

  Further, even when the switching means 2a stores the nine lighting states in advance and is set to shift in the order of illuminance, it is necessary to start and turn off the discharge lamp in the process of switching in order. There is a switching mode.

  Here, FIG. 10 shows the transition of the light output when starting the discharge lamp. The transient operation of FIG. 10 is divided into five stages. (1) is a preceding preheating region, and the filament is heated by flowing a preheating current for about 1 second to reduce the stress at the start of discharge of the discharge lamp. . In this region, basically, the lamp does not emit light due to discharge, so the light output is equal to the extinguished state. (2) is a starting region, in which a voltage necessary for starting the discharge lamp is applied between the filaments to start the discharge lamp. Keeps lit after startup. Here, the light output at this time is 70% of the full lighting mode, and the time is about 1 second. (3) is a forced full lighting area, and even if the control signal from the switching means 2a is in the dimming lighting mode, this area is fixed to the full lighting mode. Here, it is set to about 0.3 seconds. (4) is an output transition region in the dimming lighting mode, (5) is an output stable region, (3) (5) output through the (4) output transition region for about 0.3 seconds from the forced full lighting region. Transitioning to a stable region. In the full lighting mode, (3) after the forced full lighting region, the output remains 100% and the full lighting state is maintained.

  As described above, when the discharge lamp is started, the output is shifted from a substantially off state for about 1 second to a predetermined output through a transient state for about 1.6 seconds in which the output changes at about 70 to 100%. . That is, it takes about 2.6 seconds to reach a predetermined output.

  During the eight-step illuminance switching operation shown in FIG. 8 described above, the five-step switching operation related to the start of the discharge lamp inevitably requires about 2.6 seconds. Switching operation takes time.

  Here, FIG. 11 shows the transition of the light output when the light output is switched in the lighting state (g) → (b), (h) → (c) in FIG. FIG. 12 shows the transition of the light output when the light output is switched in the lighting state (b) → (g) and (c) → (h).

  In FIG. 11, the transition of the light output at the time of switching from the lighting state (g) to (b) is represented by a curve (a), and the transition of the light output at the time of switching from the lighting state (h) to (c) is represented by a curve. Shown in (a). In this case, as soon as the switching signal is input, the 100-type double tube-type annular fluorescent lamp 4 is turned off or dimmed, and at the same time, the 40-type double-tube-type annular fluorescent lamp 3 is started by the above transient operation. In order to start, the illuminance is once greatly reduced, and the illuminance gradually increases from there. It takes about 2.3 seconds from the input of the switching signal until the illuminance is completely switched. At the time of switching from the lighting state (h) to (c) indicated by the curve (A), the light is temporarily turned off.

  In FIG. 12, the transition of the light output at the time of switching from the lighting state (b) to (g) is represented by a curve (c), and the transition of the light output at the time of switching from the lighting state (c) to (h) is represented by a curve. Shown in (d). At the time of switching from the lighting state (b) to (g) shown in the curve (c), the 40-type double tube ring-shaped fluorescent lamp 3 is dimmed immediately upon input of the switching signal, and at the same time the 100-type 2 Since the heavy tube-shaped annular fluorescent lamp 4 shifts from the dimming lighting mode to the full lighting mode, the illuminance is once reduced and the illuminance immediately increases from there. It takes about 0.3 seconds from the input of the switching signal until the illuminance is completely switched. At the time of switching from the lighting state (c) to (h) indicated by the curve (d), immediately after the switching signal is input, the 40-type double tube ring-shaped fluorescent lamp 3 is turned off and at the same time the 100-type is turned on. Since the double-tube-shaped annular fluorescent lamp 4 starts to start due to the above-described transient operation, the lighting fixture itself is turned off once in spite of the operation in the direction of increasing the illuminance, and step by step from there. The operation will increase the illuminance. It takes about 2.6 seconds from the input of the switching signal until the illuminance is completely switched.

  In this way, the operation of each lamp and the required time are different for each switching operation, and when the illuminance is switched once and restored, the operation changes completely, so the illuminance changes step by step. This is an unnatural switching operation that is difficult to say.

  That is, in this conventional example, in two discharge lamps, eight levels of illuminance can be obtained except for the extinguished state by a combination of the three lighting states of full lighting mode, dimming lighting mode, and extinguishing. There is a problem that it takes time for the operation to increase or decrease, it does not operate continuously, and it is difficult for the user to understand the increase or decrease in illuminance.

In order to solve the above problems, the invention of claim 1 uses a plurality of discharge lamps 3 and 4 as light sources and supplies lighting power to the plurality of discharge lamps 3 and 4 as shown in FIG. A plurality of discharge lamp lighting devices 9, 10, and a control unit (remote control light receiving unit 9) for controlling switching on / off and switching of the lighting power of the plurality of discharge lamp lighting devices 9, 10, In a lighting fixture having an operating means (remote control transmitter) for operating and capable of switching the total light output of the plurality of discharge lamps 3 and 4 to at least a three-stage lighting mode, the plurality of discharge lamp lighting devices 9 and 10 At least one of the discharge lamp lighting devices 10 is a continuous dimming type lighting device having a function of continuously changing the lighting power of the discharge lamp 4 by continuously changing the signal from the control unit. The other at least one discharge lamp lighting device 9 is a single-output type lighting device whose lighting power cannot be switched by a signal from the control unit, or the lighting power can be switched only in two stages by a signal from the control unit 2 A stage output type lighting device, and the three-stage lighting mode includes a full lighting mode in which lighting power is supplied to all of the plurality of discharge lamp lighting devices at a maximum output of a control range of the control unit, and the at least one continuous lighting mode. Continuous dimming lighting mode in which the dimming type lighting device supplies lighting power according to the control range of the control unit, and at least one other single-output type lighting device or two-stage output type lighting device does not supply lighting power look including the door, characterized in that between the full lighting mode and the continuous dimming lighting mode, the sum of the light output of the plurality of discharge lamps 3 and 4 are changed discontinuously To.

  The invention of claim 2 is characterized in that, in claim 1, all of the plurality of discharge lamps are annular discharge lamps having different outer diameters, inner diameters and rated outputs, and these discharge lamps are arranged concentrically.

  The invention of claim 3 is the lighting device for the annular discharge lamp having the smallest outer diameter, inner diameter, and rated output arranged on the innermost side in claim 2, and is a single output type lighting device or a two-stage output type lighting device. The lighting device of the ring-shaped discharge lamp having the largest outer diameter, inner diameter, and rated output disposed on the outermost side is a continuous light control type lighting device.

  According to a fourth aspect of the present invention, in any one of the first to third aspects, the control unit that controls lighting / extinguishing of the discharge lamp lighting device and switching of the lighting power is turned on / off by a remote control signal from a remote control transmitter. And a remote control signal reception function for switching the lighting output, and a full lighting mode in which all discharge lamps are lit at a maximum output, and the single output type lighting device or the two-stage output type lighting device. The remote control transmitter is provided with an operation button for directly switching to the dimming lighting mode in which only the continuous dimming type lighting device is turned on.

  According to the first aspect of the present invention, the combination of at least one continuous light control type lighting device and a single output type lighting device or a two-stage output type lighting device allows the illuminance to be in two or three stages in a high illuminance region. Since the light intensity is changed continuously and the light intensity is continuously changed in the low illuminance area, the single output type lighting device or the two-stage lighting apparatus is used in the high illuminance area where the change in illuminance is difficult to understand. By changing the illuminance greatly by step dimming or turning off of the output type lighting device, in a low illuminance area where the change in illuminance is relatively easy to understand, only the continuous dimming type lighting device is turned on and the continuous dimming operation is performed. In addition to illuminance, a visually smooth change in illuminance can be obtained.

  According to the invention of claim 2, even when a dimming operation including turning off and individual dimming operations among a plurality of ring discharge lamps, because the annular discharge lamps are arranged concentrically, Illuminance can be switched without significantly changing the light distribution of the luminaire.

  According to the third aspect of the present invention, the illuminance is changed by step dimming or turning off the lamp with the smallest output, and the lamp with the largest output is continuously dimmed when the lamp with the smallest output is turned off. A more continuous change in light output can be obtained.

  According to the invention of claim 4, the operation for switching between the full lighting mode and the continuous light control mode and the continuous light control in the continuous light control mode is simple and easy to understand. Since the dimming mode is switched, a transient change in the light output due to the process of starting the discharge lamp during the continuous dimming operation does not occur.

  In FIG. 1, the FHD 40 lamp 3 and the FHD 100 lamp 4, the lighting device for the FHD 40 lamp 3 (hereinafter referred to as the FHD 40 lighting device) 9 and the lighting device for the built-in FHD 100 lamp 4 (hereinafter referred to as the lighting device body 1). , FHD100 lighting device) 10 and a block diagram of a configuration of a remote control light receiving unit 2 attached to the luminaire body 1 is shown.

  The configuration of the block diagram includes an FHD 40 lamp 3 attached to the luminaire main body 1, an FHD 40 lighting device 9 for supplying lighting power thereto, and an FHD 100 lamp 4 arranged on the outer periphery of the FHD 40 lamp 3 also attached to the luminaire main body 1. And the FHD 100 lighting device 10 for supplying the lighting power thereto and the remote control light receiving unit 2.

  The FHD 100 lighting device 10 receives a power supply from a commercial power source through the input connector 11 and supplies it to the input connector 14 of the FHD 40 lighting device 9 through a power feed line 13 connected to the power feed connector 12.

  Further, the FHD 100 lighting device 10 detects the energization by the potential after full-wave rectification of the commercial power supply voltage of 100 V (50/60 Hz) from the terminal a to the control power supply voltage Vcc to the remote control light receiving unit 2. Is supplied from the terminal b, and conversely, the H / L signal for controlling the lighting / extinguishing (ON / OFF) from the remote control light-receiving unit 2 is variable from the terminal c, and the on-duty for controlling the lighting output is variable. The dimming signal consisting of the pulse signal is received from the terminal d.

  On the other hand, the FHD 40 lighting device 9 receives an H / L signal for controlling lighting / extinguishing (ON / OFF) from the remote control light receiving unit 2 via the terminal f.

  Five different voltage lines obtained by adding the GND potential of the terminal e serving as the reference potential to the voltages of the terminals a to d are supplied from the first control signal connector 15 of the remote control light receiving unit 2 via the first control signal line 16. A voltage line that is connected to the control signal connector 17 of the FHD 100 lighting device 10 and adds the GND potential of the terminal g as a reference to the voltage of the terminal f is connected to the second control signal connector 18 of the remote control light receiving unit 2 from the second control signal connector 18. The control signal connector 20 of the FHD 40 lighting device 9 is connected via the second control signal line 19. Here, the GND potential of the terminal e and the terminal g is the same potential.

  The FHD 40 lamp 3 is supplied with lighting power from the output connector 21 of the FHD 40 lighting device 9 via the FHD lamp output line 22, and the FHD 100 lamp 4 is supplied with the FHD lamp output line 24 from the output connector 23 of the FHD 100 lighting device 10. Lighting power is supplied via

  The FHD 40 lighting device 9 switches on and off the FHD 40 lamp 3 by the ON / OFF signal of the terminal f, and the lamp power of the FHD 40 lamp 3 is lit at a substantially rated output at the time of lighting.

  The FHD100 lighting device 10 controls the lighting output to the FHD100 lamp 4 according to the dimming signal of the terminal d, and the lamp power of the FHD100 lamp 4 is lit at a substantially rated output in the full lighting mode. In the light-MIN (minimum) lighting mode, the lamp power is output at a rated ratio of about 15%, and the dimming ratio at this time is about 10%.

  The remote control light receiving unit 2 outputs a combination of control signals to these two lighting devices 9 and 10.

  Table 2 shows the relationship between the dimming signal (terminal d) to the FHD100 lighting device 10, the ON / OFF signal (terminal f) to the FHD40 lighting device 9, and the lighting state of each lamp at that time. It shows the transition of the light output in the mode.

  In full lighting mode (A), both lamps are lit at approximately the rated output, and when dimming operation is performed from there, the FHD40 lamp 3 is turned off and only the FHD100 lamp 4 is lit. To do. In the continuous dimming lighting mode, the FHD 100 lamp 4 operates within a range of about 100% to 15% of the rated ratio with respect to the lamp power and 100% to 10% with respect to the light output.

  FIG. 4 shows the dimming ratio of the lighting fixture in each mode. The rated luminous flux of the FHD40 lamp 3 is 3450 lm, and the rated luminous flux of the FHD100 lamp 4 is 9850 lm. Therefore, the total luminous flux in the full lighting mode (A) is 3450 + 9850 = 13300 lm. On the other hand, the total luminous flux at the minimum output in the continuous light control lighting mode (B) is 9850 × 10% = 985 lm. Therefore, the dimming ratio at this time is 985/13300 = 7.4%. It can be seen that the dimming ratio at the minimum output in the continuous dimming lighting mode (B) can be reduced by turning on the FHD 40 lamp 3 in the full lighting mode (A). In addition, the transition of the light output when the switching operation from the continuous dimming lighting mode (B) to the full lighting mode (A) which requires the activation of the FHD 40 lamp 3 is smoothed.

The all-light button 25 and the desired brightness button are used to switch between the full lighting mode (A) and the continuous dimming lighting mode (B), and the night-light button 28 lights only the light source other than the ring discharge lamp. A button for switching to the nightlight mode, and a light-off button 29 is a button for switching to a mode in which all light sources are turned off.

  Further, FIG. 6 shows the transition of the light output when the switching operation from the continuous dimming lighting mode (B) to the full lighting mode (A) which requires the activation of the FHD 40 lamp 3 is performed. The curve (o) in the figure is the transition of the light output when the maximum output in the continuous dimming lighting mode (B) is switched to the full lighting mode (A), and the curve (f) is the continuous dimming. From the lighting state in which the dimming ratio of the FHD100 lamp 4 in the lighting mode (B) is 50%, the curved line (K) is the same from the lighting state in which the dimming ratio of the FHD100 lamp 4 is 10% to the full lighting mode (A). It is the transition of the light output when switching to.

  Each curve changes the light output step by step, but it is a monotonically increasing change, such as in the conventional example, once it turns off, once it decreases, and then starts increasing, it becomes unnatural. Absent.

  According to this remote control transmitter, it is possible to provide the user with easy-to-understand changes in the dimming range and brightness by using a separate button for operations when it takes time to change the illuminance as described in the conventional example. be able to.
