[0022]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 is a conceptual diagram showing the configuration of the present invention. In the figure, 11 is a power source, 12 is a common constant power type lighting device, 13 is a connection changing means, 14 is an arbitrary number of first discharge lamps exhibiting a first light color, and 15 is a second light color. It is an arbitrary number of second discharge lamps. In addition, each discharge lamp 14, 15
Are preferably balanced so that almost equal amounts of light emission can be obtained. The connection changing means 13 includes a means 13a for changing the connection of the first discharge lamp 14 and a means 13b for changing the connection of the second discharge lamp 15. Although any number of the discharge lamps 14 and 15 can be used, it is desirable that the discharge lamps 14 and 15 have the same number for the above-mentioned reason. 16 is a remote control receiver, 17
Is a main body of the lighting fixture, and the lighting device 12, the discharge lamps 14 and 15 and the remote control receiver 16 are arranged to form a lighting fixture 18. The remote control receiver 16 controls the connection changing means 13 to selectively connect the discharge lamps 14 and 15 to the lighting device, but can further control normal blinking, dimming, and the like. The connection changing means 13 can be constituted by a switch, in which case it can be a mechanical or electronic switch.

Reference numeral 19 denotes a remote control transmitter, which is the remote control body 1
9a, a light color switching operation section 19b, a normal operation section 19c for blinking, dimming, etc., and a signal generation function 19d for transmitting a predetermined control signal according to the operation of each operation section. Since the light color switching operation section 19b is not normally operated, it may be concealed by a cover (not shown) to prevent an erroneous operation by the user.

The respective discharge lamps 14 and 15 have different emission colors. For example, the first discharge lamp has a warm emission color,
It is allowed to have a correlated color temperature of 3000 to 3500K or a light color such as a light bulb color. The second discharge lamp allows its emission color to be a cold color, a correlated color temperature of 6500 to 6700 K, or a light color such as daylight color. As the discharge lamp, for example, a fluorescent lamp can be used. A fluorescent lamp is a group of relatively high-load fluorescent lamps called a straight tube, an annular shape, and a compact shape, which are U-shaped (in the case of the applicant (hereinafter the same), FPL type), double U-shaped ( FDL type, W type (FWL type and FML type)
Various shapes such as (shape) are allowed. The rated lamp power is not particularly limited. Generally, 10-40 W for residential use and 20-11 W for facility use
0W is relatively suitable for use. In fluorescent lamps,
Although the light color is determined by the fluorescent substance, any fluorescent substance such as a rare earth fluorescent substance capable of providing primary color emission or a fluorescent substance having a continuous wavelength emission type halophosphate fluorescent substance as a main component can be used.

As the constant power type lighting device, a constant power type ballast mainly composed of an iron core and a coil operating at a commercial frequency can be used. Further, a high frequency inverter as a main component can also be used. In particular, the latter is highly efficient, has no flicker in brightness, and has a relatively easy constant power control. The operating frequency is above 20 KHz, preferably in the range of 20 to 60 KHz. In the figure, 12a is an inverter section and 12b is a current limiting section. The current limiting portion 12b is inserted in series with each discharge lamp.

Next, the operation will be described.

First, the amount of light will be described. When both the first discharge lamp 14 and the second discharge lamp 15 are connected to the lighting device 12 by the connection changing means 13, constant power is supplied from the lighting device to the load side, and the first and second discharge lamps 14, 1
5 lights at the same time. At this time, it is desirable that each discharge lamp is turned on at the rated power or the dimming state. More specifically, when one of the discharge lamps is lit independently under the supply of the constant power, the discharge lamp is 200% of its rated power.
When the high output lighting is set to 100%, the individual discharge lamps are turned on at 100% according to the rating when the discharge lamps are turned on together. Unlike the above case,
When one of the discharge lamps lights up independently,
When it is set to light at a high output of 50%, the individual discharge lamps are 75
% Dimming will be turned on. In the above description, when either one or both of the discharge lamps are lit, they are 100% in use, that is, all-light lighting. On the other hand, if the lighting device is controlled to reduce the power supplied to the load side, dimming can be performed in use. These are the normal operation unit 1 of the remote control transmitter 19 in this embodiment.
By operating 9c, the remote control receiver 16 can be operated and performed.

Next, the light color will be described. By connecting both the discharge lamps 14 and 15 to the lighting device and lighting them substantially equally by the connection changing means 13, the light colors become intermediate by mixing the light colors specific to each discharge lamp. That is, in the combination of the warm-colored and cold-colored discharge lamps, an intermediate light color can be obtained. Also, the correlated color temperatures 3000 to 3
In the case of the combination of the discharge lamps of 500K and 6500-6700K, the light color of 5200-5500K is obtained. Further, in the combination of the light bulb color and the daylight color, a daylight white light color is obtained. It should be noted that, in order to promote the light-mixing action, an appropriate light-mixing means such as a diffusion transmission plate or a diffusion reflection plate is provided in the lighting fixture alone or in combination as necessary. Next, if either one of the first and second discharge lamps 14 and 15 is selectively connected to the lighting device 12, the one discharge lamp is turned on. The light color is unique to the discharge lamp. That is, a warm color system or a cold color system, a correlated color temperature 3000 to 3
500K or 6500-6700K, bulb or daylight colors are obtained.

The output transformer a, 22 is its output winding, 23 is an input winding, 24 is a switching circuit whose output end is connected between both ends of the input winding 23, and 25 is supplied from the lighting device 12 to the discharge lamp side. A lamp current detector arranged to detect the total lamp current, 26 a lamp voltage detector arranged in each discharge lamp, and 27 a inverter unit 12a according to the outputs of both detectors 26, 27. It is a control circuit for power control. The connection changing means 13 is composed of a transistor switch circuit in which both means 13a and 13b are combined with a full-wave rectifier circuit, and is controlled by a remote control receiver or the like. The lamp current detector 25 can use known means such as a current transformer and a resistor. Further, the lamp voltage detection unit 26 is connected between both electrodes of the discharge lamp, and a known means such as a resistor can be used. Reference numeral 28 is a diode for preventing wraparound. Further, the inverter unit 12a can adopt various known circuit systems. The control circuit 27 is also controlled by the remote control receiver, and is configured to perform blinking, dimming, and the like. Reference numeral 29 is a capacitor, which is connected between the non-power supply side terminals of the discharge lamps 14 and 15 and acts so as to pass a required preheating current.

Next, the operation will be described. Since the lamp current detection unit 25 detects the total lamp current supplied from the lighting device to the load and the lamp voltage is detected by the lamp voltage detection unit 26, the outputs of both detection units are calculated by the control circuit 27 and the power signal is output. Can be obtained. By negatively feeding back this power signal to the inverter unit 12a, the lighting device 12
Can be made constant power. Therefore, the discharge lamps 14, 1
The output supplied from the lighting device 12 to the load side is constant power regardless of either one or both of No. 5 and No. 5, so that the light amount of the discharge lamp is always substantially equal.
