This invention relates to a fluorescent lamp device in which a chassis provided with a light-transmitting cover is covered with a transparent cover.

A typical example is a fluorescent lamp device that includes a transparent cover that covers a chassis that includes a fluorescent lamp and a receiver case for receiving an infrared remote control signal.

ない。In this type of fluorescent lamp equipment, the infrared light contained in the light from the fluorescent lamp is reflected on the bottom surface of the transparent cover and enters the light receiving part housed in the receiving part case of the infrared remote control signal. , or may enter directly and cause malfunction or non-operation of the flashing or dimming control of the fluorescent lamp, so careful consideration must be given to the mounting location of the light receiving section and other areas.

ものがあるのは言うまでもない。[Problem M to be solved by the invention] On the other hand, high-frequency lighting type fluorescent lamp equipment has become widespread, and there is a very strong need for this type of fluorescent lamp equipment to be an infrared remote control type. Needless to say, there is.

プ器具には、さらに因難な問題点が内在しているのが、
本発明者の実験検討により明らかとなった。However, there is a more serious problem inherent in the high-frequency activated fluorescent lamp device, which is equipped with a transparent cover that covers the chassis that includes the fluorescent lamp that is activated at high frequency and the receiver case for the infrared remote control signal. What is happening is
This became clear through experimental studies conducted by the inventor.

に大きいということである。That is, it is fundamentally different from when a fluorescent lamp is operated at a commercial power frequency of 50 Hz or 60 Hz, and when it is operated at a high frequency of, for example, about 40 kHz to about 60 kHz, the frequency is very close to the frequency of the infrared remote control signal. However, since it is technically difficult to distinguish between the two, the degree of negative impact on infrared remote control is much greater.

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, while the operating frequency of a fluorescent lamp lit at high frequency is divided into a range of about 40 kHz or higher. This is a measure taken by the industry to ensure that high frequency lighting type fluorescent lamp equipment does not adversely affect infrared remote control systems such as TVs and VTRs. Since high frequency lighting type fluorescent lamp equipment and TVs, VTRs, etc. are installed separately, no particular problem arises in this usage category.

に悪影響があるのが明白である。On the other hand, in the type of infrared remote control and high frequency lighting type fluorescent lamp equipment to which the present invention is directed, the fluorescent lamp that is lit at high frequency and the receiving part case for the infrared remote control signal are housed together in the transparent cover. Therefore, it is clear that the infrared remote control control has an incomparably negative effect.

外線リモートコントロール制御が全く不可能であった。Furthermore, as a result of various tests and studies, it has been found that when the fluorescent lamp is turned on in a low-temperature atmosphere with an ambient temperature of 5°C, the argon spectrum with a wavelength of about 910rv + 965nm is generated with considerable intensity in the initial stage of lighting. It was found that this also resulted in the infrared remote control not working or malfunctioning. That is, this spectral wavelength is the transmitting LED of the infrared remote control transmitter.
The wavelength is very close to 950 nm,9 and it must be said that it is technically impossible to distinguish between the two. In other words, the mercury spectrum is much more harmful than the well-known 1013n mercury spectrum generated during stable lighting, and infrared remote control was completely impossible in the early stages of low-temperature lighting.

The present invention constitutes an infrared remote control type high frequency lighting type fluorescent lamp device comprising a case and a translucent cover covering the chassis.

It is within the range of 25aa+, and it is also acceptable (o
The main lower surface of the case is constructed to be higher than the lower edge of the fluorescent lamp by about 2 mm or more.

白であり、コスト高になる。[Function 1] According to the present invention, even though the receiver case is located between a plurality of fluorescent lamps lit at high frequency, the adverse effects of infrared light contained in the fluorescent lamp light are very large. First, the receiver for the infrared remote control signal stored in the receiver housing of the receiver case is located almost next to the socket to which the end of the fluorescent lamp is attached, so the fluorescent lamp does not close to the side of the socket. Since the light is considerably reduced compared to that between fluorescent lamps, and therefore the infrared light contained in the fluorescent lamp light is also considerably weaker, it will not adversely affect the infrared remote control control, and the infrared remote control ( It can accurately prevent the blinking and dimming control of fluorescent lamps from not working or malfunctioning due to the above-mentioned problems.In particular, it solves the problem that infrared remote control was completely impossible during the initial stage of low-temperature lighting of fluorescent lamps. Moreover, with this solution, the receiver case can fit well within the confines of the chassis, and there is no need to make the chassis larger, so the cost impact is virtually negligible. On the other hand, if the light receiving section is installed on the back of the socket, for example, the remote control performance will be even better, but it will obviously be difficult to avoid increasing the size of the chassis, which will increase the cost.

を損なうことはない。Next, if the lower surface of the receiver case housing the light receiver is configured to be lower than the lower edge of the fluorescent lamp, and the main lower surface of the receiver case is configured to be higher than the lower edge of the fluorescent lamp, the infrared light contained in the fluorescent lamp light can be In addition to avoiding direct incidence of light into the light-receiving section, it also reduces the incidence of reflected light from the bottom of the transparent cover, further reducing its negative effects, and preventing fluorescent lamp light from entering the main underside of the receiver case. Since the light shines directly, it can accurately prevent the shadow of the main bottom surface of the receiver case from being projected onto the transparent cover.
Product value can be increased. In addition, the area where the light receiver housing is located on the lower surface is almost the same as the socket and is originally a slightly dark area, so the shadow on the lower surface of the light receiver housing is not noticeable and does not impair the product value.

成すると良い。For example, the lower surface of the receiver housing the receiver case should be approximately 21 to approximately 10+ sm lower than the lower edge of the fluorescent lamp (the distance between the lower surface of the receiver case housing the receiver case and the bottom surface of the transparent cover should be approximately 1 sm lower than the lower edge of the fluorescent lamp).
It is preferable that the distance be within the range of 0 m1 to about 25 mm, and furthermore, the main lower surface of the receiver case should be recessed by about 2 m+a or more from the lower edge of the fluorescent lamp.

。First, to explain based on FIGS. 1 to 5, on the bottom surface of the chassis 1, a high frequency lighting section 2 generates a signal of about 40 kHz to
A plurality of fluorescent lamps 3 which are lit at a high frequency of about 60 kHz are arranged in parallel. The fluorescent lamp 3 may be of a U-shape instead of a straight tube type as shown in the figure. The end of the fluorescent lamp 3 is fitted into a socket 4. A reception control unit (not shown) receives an infrared remote control signal 5 transmitted from a transmitter (not shown) and controls the fluorescent lamp 3 to blink or dim.
(not shown), the main part 6 of the receiver case 6Lt
a is located between the fluorescent lamps 3, and an infrared remote control signal 5 (
A light receiving section 6c (with a frequency within a range of about 33 kHz to about 40 kHz) is located almost beside the socket 4. A translucent cover 7 made of milky white resin or transparent street oil with prism cuts covers the chassis 1. In addition, 6d is a window hole provided in the light receiving part storage part 6b so as to face the light receiving part 6c. Generally, the infrared light transmittance of the transparent cover 7 is within the range of about 65% to about 95%, and the visible light transmittance is within the range of about 60% to about 90%. , and the transmittance of infrared light is greater than the transmittance of visible light.

It is preferable that the lower surface is higher than the lower edge of the fluorescent lamp 3.

的に困難である。First, FIG. 7 shows a state in which the fluorescent lamp 3 is stably lit, and as is well known, a mercury spectrum with a wavelength of 11013n is generated quite close to the wavelength of 950n of the transmitting LED. This mercury spectrum uses a filter (light receiving section 6
C) can be cut to some extent, but the lighting frequency of the fluorescent lamp 3 (approximately 40 to 41 Hz to approximately 60 kHz
) is the frequency of the infrared remote control signal 5 (approximately 3
(3 kHz to about 40 kHz), it is technically difficult to distinguish between the two in the device configuration targeted by the present invention.

The argon spectrum such as
They are very close to each other, and it is technically difficult to distinguish between the two, even with very expensive and high-performance filters.

This shows the reachability tll (distance perpendicular to the bottom surface of the transparent cover 7) of the infrared remote control signal 5 when the receiver case 6 is installed so that the receiver case 6 is located at the distance # shown here. It was possible to control the flashing or dimming of the light.

この図のように、Ａ点に受光部６Ｃがある場合は満足す

なかった。Points B and C are within the shaded area in Figure 2, and within this area the light from the fluorescent lamp 3 is reflected off the bottom surface of the transparent cover 7 and the interior is very bright, so it is especially difficult to see from the corner of a large room. A problem occurs when controlling a fluorescent lamp installed in the center of the ceiling of a room using infrared remote control in an oblique direction. On the other hand, in the area outside the hatched area in FIG. 2, the reflected light from the bottom surface of the transparent cover 7 of the fluorescent lamp 3 is quite weak.
The infrared light contained in the light from the fluorescent lamp 3 was also considerably reduced, and there was no particular adverse effect on the infrared remote control.

This figure shows the relationship between the distance (d2) between the lower surface of b and the bottom surface of the transparent cover 7 and the reach distance of the infrared remote control signal 5, which was measured by changing the height of the transparent cover 7. As is clear from this figure, d2 is approximately 10
Although the reach distance is very good within am, it is clearly visible that the shadow of the receiver case 6 is projected on the transparent cover 7.
I was unsatisfied with the product value. Also, d2 is about 25n
At +m or more, there is no such problem, but the reach distance becomes extremely poor. Furthermore, within the range of d2 of about 10 m or more and 25 mm, the reach was about 10 m or more, and moreover, the shadow of the receiver case 6 could hardly be seen projected onto the transparent cover 7, so a satisfactory result was obtained. . Note that the dotted point in this figure has a reach distance of approximately 16 m, and is the same as the light receiving part 6 in Figure 8.
This corresponds to the reach distance of point A at position c. That is, FIG. 8 shows measurements taken by changing the position of the light receiving section 6c when d2 is approximately 17 mm. Also, Figures 8 and 9 are

あり、コスト高になる。According to the above configuration, the receiver case 6 is located between the plurality of fluorescent lamps 3 that can be lit at high frequency, and even though the adverse effect of infrared light contained in the fluorescent lamp light is very large, the receiver Since the light receiving part 6c of the infrared remote control 48 5 housed in the light receiving part storage part 6b of the case 6 is located almost next to the socket 4 to which the end of the fluorescent lamp 3 is attached, it is located almost at the center of the socket 4. In this case, the fluorescent lamp light has decreased considerably compared to the fluorescent lamp 3 period, and therefore,
Since the infrared light contained in the fluorescent lamp light is also considerably weak, it will not have any negative effect on the infrared remote control, and the blinking or dimming control of the fluorescent lamp 3 by the infrared remote control signal will not work or malfunction. can be accurately prevented. In particular, it is possible to solve the problem that infrared remote control was completely impossible during the early stage of low-temperature lighting of the fluorescent lamp 3. Furthermore, according to this solution, the receiver case 6 can be well accommodated within the range of the chassis 1, and there is no need to increase the size of the chassis 1, so there is virtually no impact on costs. . On the other hand, if the light receiving section 6c is installed on the back of the socket 4, for example, the remote control performance will be even better, but it is obvious that it will be difficult to avoid increasing the size of the chassis 1, which will increase the cost. .

品価値を損なうことはない。Next, if the lower surface of the light receiving section accommodating portion 6b of the receiving section case 6 is configured to be lower than the lower edge of the fluorescent lamp 3, and the lower surface of the main portion 6a of the receiving section case 6 is configured to be higher than the lower edge of the fluorescent lamp 3, Not only can the infrared light included in the fluorescent lamp light be prevented from directly entering the light-receiving section storage section 6b, but also the incidence of reflected light from the bottom surface of the transparent cover 7 can be reduced, and its negative effects can be further reduced. Since the fluorescent lamp light directly hits the lower surface of the main portion 6a of the 8-part case 6, the shadow of the lower surface of the main portion 6a is properly prevented from being projected onto the transparent cover 7. In addition, the lower surface of the light-receiving section accommodating section 6b is located almost beside the socket 4 and is originally a slightly dark part, so the shadow on the lower surface of the light-receiving section accommodating section 6b is not noticeable. It will not damage.
