Abstract

PROBLEM TO BE SOLVED: To improve an outdoor low-temperature starting property by providing inside a luminaire heating means controlled by a temperature sensor and a photosensor. SOLUTION: When temperature is low for the lighting of a fluorescent lamp 11 and the illuminance of the environment around a luminaire is lower than the prescribed illuminance, a photosensor section 15 excites a power supply 13, a ballast 12 turns on the fluorescent lamp 11, and a temperature sensor section 14 excites and starts a luminaire heating means 16. The inside of the luminaire is heated, and the low-temperature starting property of the fluorescent lamp 11 can be improved. When the sealing property of the luminaire is increased, the temperature in it is increased by the self-heating of the fluorescent lamp 11, and the light output of the fluorescent lamp 11 is stabilized by merely assisting the heating at the time of a lighting action. The temperature sensor section 14 de-excites the luminaire heating means 16 when the temperature becomes sufficiently high for the lighting action, and unnecessary heating is suppressed for energy saving after the light output of the fluorescent lamp 11 is stabilized.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluorescent lamp outdoor lighting apparatus, a fluorescent lamp outdoor lighting apparatus controller, and a fluorescent lamp lighting tube.

[0002]

2. Description of the Related Art As a conventional fluorescent lamp temperature detecting means and its control technique, a thermo switch is used in a fluorescent lamp lighting device in a freezing room, and when a temperature around the lighting device is low at the time of starting lighting, a heating wire is used. Turn on the heater,
2. Description of the Related Art Fluorescent lamp luminaires for cold rooms that assist in starting a fluorescent lamp at low temperatures are known. At a low temperature, these heating means are used because at a low temperature, Hg in the fluorescent lamp does not evaporate and the vapor pressure of Hg decreases (25 [°] = 0.00).
12 [mmHg], 0 [°] = 0.0000185 [mmHg]), which makes it difficult to start the fluorescent lamp.

As a conventional technique for detecting the illuminance of a fluorescent lamp and controlling the same, a CdS photoelectric sensor or a phototransistor is used to control the lighting with a relay switch when the environment around the lighting fixture becomes dark. Lighting fixtures are known. In outdoor lighting, control for turning on a lighting device is generally performed by detecting that the surrounding environment has become dark with an optical sensor.

The problem to be solved by the present invention is to improve the cold startability of a fluorescent lamp when used outdoors. General fluorescent lamps are presumed to be used indoors, and when used in a situation where the temperature changes drastically, such as outdoors, the luminous flux is reduced during use.

[0005] Particularly, in outdoor use in winter, since the ambient temperature is reduced, the characteristics of the fluorescent lamp are greatly reduced more than a predetermined value because it is designed to exhibit the best characteristics at 25 °.

In particular, at a low temperature, the lamp starting voltage is extremely large because the mercury vapor pressure having a low ionization voltage is extremely lower than the vapor pressure of a rare gas (Ne, Ar, Kr, etc.) having a high ionization voltage in the lamp. Rises.

At the same time, the penning effect (the effect of lowering the firing voltage when a penning gas such as Ne, Ar, or Kr is present than a single gas of mercury vapor) is reduced, making it difficult to start the lamp. .

For this reason, even when the fluorescent lamp is placed in a closed type appliance, it is said that 0 to -10 ° C. is the limit of low temperature starting of the fluorescent lamp. For this reason, in an area where the temperature often drops below zero in winter, fluorescent lamps cannot be used for outdoor lighting.

However, once the fluorescent lamp is turned on, the interior of the closed type appliance becomes 20-30 ° C. higher than the outside air temperature due to self-heating of the lamp. This problem can be solved.

Accordingly, an object of the present invention is to improve the low temperature startability of an outdoor lighting device for a fluorescent lamp when the fluorescent lamp is used for outdoor lighting.

Heretofore, there has hitherto not been any luminaire in which a temperature sensor and an illuminance sensor are combined and the heating means in the lamp functions at low illuminance and low temperature. In addition, there is no device in which the ballast or the lighting tube has a temperature sensor and controls the electric startability at a low temperature.

In the first and third aspects of the present invention, it is preferable to start the heating means in the lamp before starting the fluorescent lamp start control.

In the first and third aspects of the present invention, it is preferable that the heating means in the lamp is de-energized after the light output of the fluorescent lamp is stabilized.

(First Embodiment) FIG. 1 shows a typical embodiment of an outdoor lighting apparatus for a fluorescent lamp according to the present invention. FIG. 1 is a typical principle view of a first embodiment of a lighting device for a fluorescent lamp according to the present invention.

In the figure, 11 is a fluorescent lamp, 12 is a ballast,
13 is a power supply, 14 is a temperature sensor unit, 15 is an optical sensor unit,
Reference numeral 16 denotes a lamp heating means.

In a state where the temperature is sufficiently high for the lighting operation of the fluorescent lamp, when the illuminance of the environment around the lighting fixture falls below a predetermined illuminance, the optical sensor unit 15 turns on the power supply 13 and the ballast 12 switches the fluorescent lamp 11 Lights up. At this time, the temperature sensor unit 14 does not turn on the power supply 13 and does not start the heating unit 16 in the lamp.

Conversely, when the illuminance of the environment around the luminaire falls below a predetermined illuminance in a state where the temperature is low with respect to the lighting operation of the fluorescent lamp, the optical sensor unit 15 turns on the power supply 13 and the ballast 12 operates. 11 is turned on. At this time, the temperature sensor unit 14 turns on the power supply 13 and starts the heating unit 16 in the lamp.

As a result, the inside of the lamp is heated, and the low temperature startability of the fluorescent lamp is improved. Here, if the hermeticity of the fluorescent lamp outdoor lighting device is enhanced, the temperature inside the lamp increases due to the self-heating of the fluorescent lamp, so that the light output of the fluorescent lamp is stabilized only by assisting the heating during the lighting operation. .

For this reason, if the in-lamp heating means 16 is provided with a control means for turning off electricity after the light output of the fluorescent lamp is stabilized, unnecessary heating is suppressed and energy is saved.

As an embodiment of the control means in which the heating means 16 in the lamp is de-energized after the light output of the fluorescent lamp is stabilized, there is a method of indirectly detecting information on the light output of the fluorescent lamp from the temperature sensor section 14. is there.

If the light output of the fluorescent lamp increases, the heat generated by the lamp increases, and the temperature rises.
In step 4, information on the light output of the fluorescent lamp 11 can be inferred and detected.

Here, the temperature sensor section 14 has a characteristic that when the temperature is sufficiently high for the lighting operation of the fluorescent lamp 11, the power supply 13 is not turned on and the in-lamp heating means 16 is not started. Irrespective of the increase in the number of lamps, the in-lamp heating means 16 can be provided with a control means that is de-energized after the light output of the fluorescent lamp 11 is stabilized.

Here, the following method can be considered as means for detecting the stability of the light output of the fluorescent lamp 11 after the lighting operation.

1. Method of detecting light output information of fluorescent lamp from light sensor unit It is possible to detect light information from one light sensor unit. And a means for detecting the light output of the fluorescent lamp, a more reliable operation can be guaranteed.

2. Method of Detecting Light Output Information of Fluorescent Lamp from Lamp Current and Lamp Voltage By detecting the lamp current, the lamp voltage, or both, it is possible to detect the light output of the fluorescent lamp.

Further, the temperature sensor has control means for starting the heating means in the lamp with a light quantity higher than the light quantity at which the light sensor section starts the fluorescent lamp starting control, so that the fluorescent lamp can be warmed before the fluorescent lamp is turned on at a low temperature. Is possible, which leads to an improvement in low-temperature starting characteristics.

When the temperature sensor implements control means for starting the heating means in the lamp with a light amount higher than the light amount at which the light sensor section starts the control of starting the fluorescent lamp, the output of the photoelectric conversion element of the light sensor section is monitored. At a predetermined light amount higher than the light amount at which the optical sensor unit starts the fluorescent lamp start control,
In addition, the temperature sensor section only needs to start the heating means in the lamp.

At low temperatures, when the light sensor detects the amount of light to start the fluorescent lamp start control, first, the heating means in the lamp is started, and then the fluorescent lamp start control is started by time control by delay. The effect of is obtained.

In the case where a controller for a fluorescent lamp outdoor luminaire equipped with a heating means in a lamp controlled by a sensor unit having a temperature sensor unit and a light sensor unit is implemented, it may be incorporated into an existing fluorescent lamp outdoor luminaire. Thus, the above-described effect can be easily obtained.

Note that the temperature sensor section is a thermoswitch,
The light sensor unit may be configured as a photo transistor and a solid state relay, or may be configured integrally with a control unit such as a built-in relay. Means are controlled.

Further, if the heating means in the lamp is a thermoelectric heater, the cost can be reduced. If the lamp is an incandescent lamp, it is possible to obtain illumination with the incandescent lamp before starting the fluorescent lamp together with preheating. .

(Second Embodiment) FIG. 2 is a view showing a representative principle of a second embodiment of a lighting apparatus for a fluorescent lamp according to the present invention.
In the figure, 21 is a fluorescent lamp, 22 is a ballast, 23 is a power supply,
Reference numeral 24 denotes a temperature sensor unit, and 25 denotes an optical sensor unit.

In a state where the temperature is sufficiently high for the lighting operation of the fluorescent lamp, when the illuminance of the environment around the lighting fixture falls below a predetermined illuminance, the optical sensor unit 25 turns on the power supply 23 and the ballast 22 switches the fluorescent lamp 21. Lights up. At this time, the temperature sensor unit 24 sets the starting voltage of the ballast 22 to a normal voltage.

Conversely, if the illuminance of the environment around the luminaire falls below a predetermined illuminance in a state where the temperature is lower than the lighting operation of the fluorescent lamp, the optical sensor unit 25 turns on the power supply 23 and the ballast 22 operates. 21 is turned on. At this time, the temperature sensor unit 24 sets the starting voltage of the ballast 22 higher than a normal voltage.

As a result, the low-temperature startability of a fluorescent lamp requiring a higher starting voltage at low temperatures is improved. here,
When the ballast 22 is an electronic ballast, control of the starting voltage in the electronic circuit becomes easy.

Although the control of the starting voltage of the ballast is increased in the embodiment, the same effect can be obtained by the control of increasing the lamp preheating and the control of increasing the lamp preheating time. Further increase.

When an outdoor lighting apparatus for a fluorescent lamp having both the realizing means of the first and second embodiments is realized, the effect is further enhanced.

(Third Embodiment) FIG. 3 is a typical principle diagram of a third embodiment of a fluorescent lamp lighting apparatus according to the present invention.

When the illuminance of the environment around the luminaire falls below a predetermined illuminance in a state where the temperature is sufficiently high for the lighting operation of the fluorescent lamp, the optical sensor unit 35 turns on the power supply 33 and the ballast 32 operates the fluorescent lamp 31. Lights up.

At this time, the temperature sensor section 34 incorporated in the fluorescent lamp lighting tube 36 sets the starting voltage of the ballast 32 to a normal voltage.

Conversely, when the illuminance of the environment around the lighting fixture is lower than a predetermined illuminance in a state where the temperature is low with respect to the lighting operation of the fluorescent lamp, the optical sensor unit 35 turns on the power supply 33 and the ballast 32 operates. The fluorescent lamp 31 is turned on. At this time, the temperature sensor unit 34 incorporated in the fluorescent lamp lighting tube 36 sets the starting voltage of the ballast 32 higher than the normal voltage. This improves the low-temperature startability of a fluorescent lamp that requires a higher starting voltage at low temperatures.

Here, if the lighting tube 36 is an electronic lighting tube, it is easy to control the starting voltage in the electronic circuit. The effect of the present invention can be easily obtained by using the lighting tube in place of a conventional lighting tube and incorporating it into an existing fluorescent lamp outdoor lighting fixture.

As described above, the conventional lighting equipment for fluorescent lamps was premised on the lighting operation when the temperature of the surrounding environment was 0 ° C. or higher, but in the present invention, the temperature sensor and the illuminance sensor are combined. Thus, if the heater of the heating means in the lamp is energized only at the time of low illuminance and at the time of low-temperature start, low-temperature startability can be improved with a small amount of preheating power.
