Abstract

<P>PROBLEM TO BE SOLVED: To provide a light control type lighting device with a reduced size restraining power consumption and heat generation. <P>SOLUTION: As a fluorescent lamp circuit 50 is an inductive circuit, an output of a fluorescent lamp 52 is restrained and the light is controlled when an output frequency is heightened. A fan circuit 60 is a capacity circuit including a phase advancing capacitor 64. When the output frequency is heightened, an output of a fan motor 63 is increased to increase an air volume. Accordingly, the air blow volume is restrained when the light output is made maximum, and the light output is restrained when the air blow volume is made maximum. By the above, such a large power consumption in which both the light output and the air blow volume become maximum is avoided, heat generation amount is restrained, and the size of the light control type lighting device is reduced. <P>COPYRIGHT: (C)2004,JPO&NCIPI

【発明の属する技術分野】
本発明はマイナスイオン発生器付き調光形照明灯に関する。
【0002】
【従来の技術】
調光形点灯装置を備え、前記調光形点灯装置から給電を受けて点灯する光出力可変形の光源を備え、マイナスイオン発生器を備え、マイナスイオンを送風する送風量可変形のファンを備えるマイナスイオン発生器付き調光形照明灯は普通の照明灯よりも消費電力大・発熱大となり、器具外郭も大形となる。
【0003】
【発明が解決しようとする課題】
本発明は消費電力・発熱を抑制し、小形化をはかることを目的とするものである。
【課題を解決するための手段】
本発明は光出力を最大としたときに送風量を制限し、前記送風量を最大としたときに前記光出力を制限する。
【0004】
【発明の実施の形態】
図1は本発明に係る調光形照明灯の回路図である。この図1を用いて、本発明の実施形態について説明する。10はマイナスイオン発生器、20は商用電源、30は整流回路、40は点灯用インバータである。点灯用インバータ40はスイッチング素子41・42、フライホイールダイオード43・44、アーム用コンデンサ45・46、高周波出力端子A・Bを含む。50は蛍光灯回路である。蛍光灯回路50はバラストインダクタ51、蛍光ランプ52、予熱用コンデンサ53を含む。60はファン回路である。ファン回路60はダウントランス61、整流回路62、ファンモータ63、コンデンサ64を含む。
商用電源20で、マイナスイオン発生器10が付勢され、また整流回路30・点灯用インバータ40が付勢される。点灯用インバータ40の高周波出力で、蛍光灯回路50・ファン回路60を付勢される。ファンモータ63には図外のファンが付属し、マイナスイオン発生器10に生ずるマイナスイオンを送風する。
点灯用インバータ40は調光形であり、スイッチング素子41・42に付属する図外のスイッチング制御回路で点灯用インバータ40の出力周波数を適宜に可変する。蛍光灯回路50は誘導性回路であるため、出力周波数が高めると蛍光ランプ52出力が制限され、調光がなされる。出力周波数を低めると、蛍光ランプ52出力が増し、光出力が増大する。
ファン回路60は進相用のコンデンサ64を含む容量回路である。出力周波数が高まると、ファンモータ63出力が増大し、送風量が増す。よって、光出力を最大としたときに送風量を制限し、送風量を最大としたときに光出力を制限する特性となる。これにより、光出力が最大となり、かつ送風量も最大となる大電力消費の運用を回避し、全体の消費電力を抑制し、発熱量を抑制し、調光形照明灯の小形化を実現する。小形であると、熱がこもり、過熱するが、本発明においては発熱量を抑制し、過熱を緩和する。
【0005】
【発明の効果】
光源の光出力を最大としたときにファン送風量を制限し、ファン送風量を最大としたときに光源の光出力を制限することにより、最大電力を抑制し、発熱を抑え、照明灯の小形化を実現する。

[Prior art]
A dimmable lighting device; a variable light output light source that is lit by receiving power from the dimmable lighting device; a negative ion generator; and a variable air flow fan that blows negative ions. Dimmable lighting with a negative ion generator consumes more power and generates more heat than ordinary lighting, and the outer casing of the equipment is also large.
[0003]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION An object of the present invention is to reduce power consumption and heat generation and to reduce the size.
[Means for Solving the Problems]
According to the present invention, the amount of air is limited when the light output is maximized, and the light output is limited when the amount of air is maximized.
[0004]
BEST MODE FOR CARRYING OUT THE INVENTION
FIG. 1 is a circuit diagram of a dimmable illumination lamp according to the present invention. An embodiment of the present invention will be described with reference to FIG. 10 is a negative ion generator, 20 is a commercial power supply, 30 is a rectifier circuit, and 40 is a lighting inverter. The lighting inverter 40 includes switching elements 41 and 42, flywheel diodes 43 and 44, arm capacitors 45 and 46, and high-frequency output terminals A and B. 50 is a fluorescent lamp circuit. The fluorescent lamp circuit 50 includes a ballast inductor 51, a fluorescent lamp 52, and a preheating capacitor 53. 60 is a fan circuit. The fan circuit 60 includes a down transformer 61, a rectifier circuit 62, a fan motor 63, and a capacitor 64.
With the commercial power supply 20, the negative ion generator 10 is energized, and the rectifier circuit 30 and the lighting inverter 40 are energized. The high frequency output of the lighting inverter 40 energizes the fluorescent lamp circuit 50 and the fan circuit 60. A fan (not shown) is attached to the fan motor 63 and blows negative ions generated in the negative ion generator 10.
The lighting inverter 40 is of a dimming type, and the output frequency of the lighting inverter 40 is appropriately varied by a switching control circuit (not shown) attached to the switching elements 41 and 42. Since the fluorescent lamp circuit 50 is an inductive circuit, when the output frequency is increased, the output of the fluorescent lamp 52 is limited, and light control is performed. When the output frequency is lowered, the output of the fluorescent lamp 52 increases, and the light output increases.
The fan circuit 60 is a capacitance circuit including a capacitor for phase advance 64. When the output frequency increases, the output of the fan motor 63 increases, and the amount of air blow increases. Therefore, the air volume is limited when the optical output is maximized, and the optical output is limited when the air volume is maximized. As a result, it is possible to avoid the operation of large power consumption in which the light output is maximized and the air volume is also maximized, suppress the overall power consumption, suppress the heat generation, and realize a compact dimmable lighting. . In the case of a small size, heat builds up and overheats, but in the present invention, the calorific value is suppressed and the overheating is eased.

【The invention's effect】
By limiting the fan airflow when the light output of the light source is maximized, and by limiting the light output of the light source when the fan airflow is maximized, the maximum power is suppressed, heat generation is suppressed, and the size of the illumination lamp is reduced. Realization.
