のである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an infrared remote control type fluorescent lamp apparatus, and in particular, it is intended to eliminate as much as possible the adverse effects on the infrared remote control during the initial stage of low-temperature lighting.

い。[Prior Art] In general, infrared remote control and fluorescent lamp equipment are not compatible, and if a large amount of infrared light contained in the light of the fluorescent lamp enters the infrared remote control signal receiving part, the infrared remote control signal In order to cause the flashing and dimming control of the fluorescent lamp to malfunction or not work, the mounting part of the light receiving part and other parts may be changed, for example, to
It is necessary to consider the issue thoroughly as in the case of Publication No. 160610.
これは、周知の通り螢光ランプの点灯時に赤外域で発生
している波長11013nの水銀スペクトルによって、
赤外線リモートコントロールが悪影響を受けるためであ
る。As is well known, this is caused by the mercury spectrum with a wavelength of 11013n, which is generated in the infrared region when a fluorescent lamp is lit.
This is because infrared remote control is adversely affected.

で水銀スペクトルを遮断する考え方が開示されている。Furthermore, according to Japanese Patent Application Laid-Open No. 57-25738, although it is not an infrared remote control fluorescent lamp device, in order to prevent the fluorescent lamp device from interfering with an infrared remote control system such as a TV, The idea of blocking the mercury spectrum with a short-pass filter that blocks 70% or more of the wavelength range has been disclosed.
[発明が解決しようとする課題]
ところが、本発明者が種々試験検討した結果によれば、

することが分かった。[Problem to be solved by the invention] However, according to the results of various tests and studies conducted by the present inventor,
When lit in a low-temperature atmosphere with an ambient temperature of 5°C, the wavelengths of 740nm and 760nm are emitted from the fluorescent lamp at the initial stage of lighting.
, 810n1, 830nm, 840n proverb, 910ng
It was found that a large number of argon spectra such as +, 965 nm, etc. were generated with considerable intensity, and this also caused the infrared remote control to be inoperable or malfunction.
これらのアルゴンスペクトルは前述の水銀スペクトルよ

クトルを遮断するだけでは遮断できなく、低温点灯初期
には赤外線リモートコントロールに重大な影響があった
。These argon spectra are much more harmful than the mercury spectra mentioned above, and cannot be blocked simply by blocking the mercury spectra with a short-pass filter, which seriously affected infrared remote control in the early stages of low-temperature lighting.
また、この影響は螢光ランプが高周波点灯される場合に
特に問題になる。Furthermore, this effect is particularly problematic when the fluorescent lamp is operated at high frequency.

赤外線リモートコントロール信号の周波数に非常に近く
、両者の弁別が技術的に困難なため、赤外線リモートコ

ということである。That is, unlike when a fluorescent lamp is lit at a commercial power frequency of 50 Hz or 60 Hz, for example, a frequency of approximately 40 Hz
When lighting at a high frequency of kHz to approximately 60kHz,
Since the frequency is very close to that of the infrared remote control signal and it is technically difficult to distinguish between the two, it has a much greater negative effect on infrared remote control control.

で配慮したものである。そして、高周波点灯型螢光ラン
プ器具とTV、VTR等はかなり離れて設Mされるため
、この使用区分で特段の問題は発生しない。Generally, the frequency of an infrared remote control signal is within a range of about 33 kHz to about 40 kHz, and the operating frequency of a fluorescent lamp lit at high frequency is divided into a range of about 40 kHz or more. This is a consideration in the industry to ensure that high-frequency lighting type fluorescent lamp fittings do not adversely affect infrared remote control systems such as TVs and VTRs. Since the high-frequency lighting type fluorescent lamp equipment and the TV, VTR, etc. are installed quite far apart, no particular problem arises in this classification of usage.

リモートコントロール式螢光ランプ器具を構成する。[Means for Solving the Problems] The present invention provides an infrared remote control type fluorescent lamp apparatus in which a light receiving section for an infrared remote control signal is provided at a location where infrared light of a fluorescent lamp is received. A long-pass filter is installed in the infrared remote control signal, and this long-pass filter contains wavelengths slightly shorter than the wavelength of the infrared remote control signal so as to block most of the many argon spectra generated in the infrared region during the initial low-temperature operation of the fluorescent lamp. An infrared remote control type fluorescent lamp device is constructed which has a characteristic of blocking shorter wavelength ranges and transmitting longer wavelength ranges including the wavelength of the infrared remote control signal.

る。In addition, a band-pass filter is provided in place of the long-pass filter. In addition to blocking wavelengths that include slightly shorter wavelengths and shorter wavelengths, it also blocks wavelengths that are longer than this, including the mercury spectrum that occurs when a fluorescent lamp is stably lit, and transmits wavelengths near the wavelength of infrared remote control signals. It can be made to have the following characteristics.

The light receiving part is housed in a light receiving part housing part with a part of the receiving part case protruding downward, and the lower surface of this light receiving part housing is located near the lower edge of the fluorescent lamp. The lower surface of the receiver case other than the light receiver housing can be made higher than the lower edge of the fluorescent lamp.

のを相当改善できる。[Function] According to the infrared remote control type fluorescent lamp apparatus of the present invention, the long pass filter provided in front of the infrared remote control signal receiving section absorbs a large number of light waves generated in the infrared region at the initial stage of low-temperature lighting of the fluorescent lamp. Since most of the argon spectrum is blocked, it is possible to considerably improve the inoperability or malfunction of the blinking and dimming control of the fluorescent lamp by infrared remote control signals during the initial stage of low-temperature lighting of the fluorescent lamp.

By blocking the spectrum, it is also possible to improve the inoperability or malfunction of the flashing and dimming control of the fluorescent lamp by infrared remote control signals.

少限にでき、商品価値を阻害しない。Furthermore, on the underside of the chassis, we installed a plurality of fluorescent lamps arranged in parallel that are lit at high frequency, and a receiver case located between the fluorescent lamps that houses the receiver for infrared remote control signals, and is covered with a transparent cover. In infrared remote control type fluorescent lamp equipment with a covering structure, the negative effect is particularly large, but the light receiving part is housed in a light receiving part housing part with a part of the receiving part case protruding downward, and this light receiving part storing part By making the bottom surface lower than the lower edge of the fluorescent lamp, you can not only prevent infrared light contained in the fluorescent lamp light from entering the receiver directly, but also reduce the incidence of reflected light from the bottom of the transparent cover. In addition to reducing the negative effects, by protruding only the light receiving part housing part of the receiving part case downward and making the part of the receiving part case other than the light receiving part storing part higher than the lower edge of the fluorescent lamp, the fluorescent lamp light is not transmitted to this part. The shadow of the receiver case can be minimized from being projected onto the translucent cover, and the product value will not be affected.

少限にでき、商品価値を阻害しない。Furthermore, on the underside of the chassis, we installed a plurality of fluorescent lamps arranged in parallel that are lit at high frequency, and a receiver case located between the fluorescent lamps that houses the receiver for infrared remote control signals, and is covered with a transparent cover. In infrared remote control type fluorescent lamp equipment with a covering structure, the negative effect is particularly large, but the light receiving part is housed in a light receiving part housing part with a part of the receiving part case protruding downward, and this light receiving part storing part By making the bottom surface lower than the lower edge of the fluorescent lamp, you can not only prevent infrared light contained in the fluorescent lamp light from entering the receiver directly, but also reduce the incidence of reflected light from the bottom of the transparent cover. In addition to reducing the negative effects, by protruding only the light receiving part housing part of the receiving part case to the bottom surface and making the part of the receiving part case other than the light receiving part storing part higher than the lower edge of the fluorescent lamp, the fluorescent lamp light is not transmitted to this part. The shadow of the receiver case can be minimized from being projected onto the translucent cover, and the product value will not be affected.
