Description

  The present invention relates to a fluorescent lamp device that can enhance the lighting effect and the advertising effect.

Various advertising devices using fluorescent lamps have been proposed and known (see, for example, Patent Documents 1 and 2).
JP-A-11-185518 JP 11-2224068 A

  The advertising device described in Japanese Patent Laid-Open No. 11-185518 includes a tube having cylindrical holders at both ends and fitted into a straight tube type fluorescent lamp, and comes out of the fluorescent lamp on the outer peripheral surface of the tube. In addition to applying an ultraviolet blocking substance that blocks ultraviolet rays, a silk printing part printed with a company name or product name is provided, and the silk printing part is illuminated with a fluorescent lamp. According to such an advertising device, when the light emitted from the fluorescent light passes through the tube and the silk print portion, the color of the characters and designs printed on the silk print portion is clearly transcribed. It is said that viewers feel a sense of aesthetics and have an excellent advertising effect.

  The electrical decoration device described in the above-mentioned Japanese Patent Application Laid-Open No. 11-2224068 is a fluorescent lamp provided with a predetermined interval on one end side of the signboard body, and a signboard body composed of one or a plurality of light-transmitting plates superimposed. A light emitting body such as an LED; a cylindrical rotating body provided on the outer peripheral side of the light emitting body along the translucent plate; and a case for supporting the rotating body and the signboard body. The rotating body is irradiated from the inside by the body, the light transmitted through the rotating body is guided into the signboard body, and the uneven processing as an advertising medium formed on the signboard body is illuminated. The rotating body is subjected to a predetermined coloring process so that light from the light emitting body is discolored by rotation. According to such an electrical decoration device, when the rotating body is rotated by a motor, the irregularities that are the advertising medium of the signboard body are irradiated with the discolored light, so the advertising medium becomes a moving image and strongly attracts the eyes. , The advertising effect can be improved.

  In addition, as an advertising medium in a train, as shown in FIG. 9, a company name, a product name, a campaign, etc. are silk-printed on the fluorescent lamp 1 in the car, and the silk-printed portion 2 is directly illuminated by the fluorescent lamp 1. Things are also known.

However, since the advertising device described in the above-mentioned JP-A-11-185518 requires a translucent tube printed with a silk print portion and a pair of holders attached to both ends of the tube, There was a problem that the number of parts increased.
Further, since a normal fluorescent lamp is a glass tube having an outer diameter of 32 mm, when the silk print portion is printed in parallel with the axis of the glass tube, the visible width when the silk print portion is viewed from the front is 22 mm. The angle range that can be visually recognized in the circumferential direction of the glass tube is extremely narrow, and depending on the tube mounting angle with respect to the glass tube, the entire silk print part cannot be seen, and the size of the silk print part is limited. receive. For this reason, the width of the silk-printed portion cannot be increased. In particular, when the characters are small, there is a problem that it is difficult to read from a distance and a sufficient advertisement effect cannot be obtained.

  The electrical decoration device described in the above-mentioned Japanese Patent Application Laid-Open No. 11-2224068 is provided with a signboard body and a rotating body, so that the device itself is enlarged and cannot be used by being installed on the ceiling or wall surface of the store. There was a problem.

  In the fluorescent lamp device in which the company name and the like are silk-printed on the fluorescent lamp 1 in the vehicle shown in FIG. 9, similarly to the advertising apparatus described in the above-mentioned JP-A-11-185518, it is visible in the circumferential direction of the glass tube. There was a problem that the range was narrow.

  In this case, in order to facilitate visual recognition of the silk print portion 2, usually, a plurality of silk print portions 2 are printed obliquely while being shifted little by little in the longitudinal direction and the circumferential direction of the glass tube 3, as shown in FIG. Thus, the characters that are visible and the characters that are not visible in each silk printing unit 2 are slightly different. Therefore, when the passenger reads all the characters displayed on the silk printing unit 2, the user turns the neck and moves the eyes along the fluorescent lamp 1 to sequentially read the characters visible on each silk printing unit 2. There is a need. In other words, it is not preferable because it expects the passenger to turn his / her neck or move his / her eyes to read the characters displayed on the silk printing unit 2.

  The present invention has been made to solve the above-described conventional problems, and the object of the present invention is to reduce the burden on the viewer without having to turn the neck and move the eyes to the left and right. Also, it is possible to provide a fluorescent lamp device capable of expanding the visibility and the range of visibility of the length and size of the display portion formed in the fluorescent lamp and enhancing the lighting effect and the advertising effect. It is in.

  In order to achieve the above object, a first invention includes a fixture body having a pair of sockets facing each other and attached to a ceiling, a wall surface, and the like, and a fluorescent lamp inserted and connected to the pair of sockets. In the fluorescent lamp device, a display unit made of a pattern, letters, symbols, etc. is formed on the outer peripheral surface of the glass tube of the fluorescent lamp, and a driving device for rotating the fluorescent lamp together with the socket is provided on the instrument body. .

  According to a second aspect of the present invention, there is provided a pair of socket mounting portions facing each other on the instrument body, each of the socket mounting portions is provided with a pair of sliding contact pieces and a rotatable socket holder for holding the socket. Of the socket holders, each of which is connected to the outer peripheral surface of the holder and provided with a pair of conductive rings for power feeding that the pair of sliding contact pieces are slidably contacted, Either one is connected to the output shaft of the drive device.

In the first aspect of the invention, when the fluorescent lamp is rotated by the driving device, the display unit also rotates and moves together with the fluorescent lamp. Therefore, the portion of the display unit that has been visible so far enters the blind spot, and conversely becomes the blind spot. The part that was not visible can be seen. Therefore, the entire display unit can be visually recognized reliably, and the visible range in the circumferential direction of the glass tube can be enlarged.
Further, since the display portion can be enlarged, it is easy to read characters, symbols, etc., and the lighting effect and the advertising effect can be enhanced.
Further, even when a plurality of display units are provided, it is only necessary to look at any one display unit, and it is not necessary to turn the neck or move the eyes greatly.

  In the second aspect of the invention, since the power supply conductive ring and the sliding contact piece are provided, the fluorescent lamp can be reliably energized.

A transparent cover 61 that covers the fluorescent lamp 1 is attached below the instrument body 11. The transparent cover 61 is formed by a transparent acrylic resin so that the upper surface and both end faces in the longitudinal direction are open, the cross-sectional shape perpendicular to the longitudinal direction is U-shaped, and the opening at both ends is the outer peripheral surface of the lower end of the cover 60. And is fixed by screws.

  In the fluorescent lamp device 10 having such a structure, when the switch is turned on and a predetermined voltage is applied to each filament electrode 19 of the fluorescent lamp 1, the filament electrode 19 is heated and emits thermoelectrons. The thermoelectrons collide with mercury atoms in the glass tube 12 to cause discharge and emit ultraviolet rays. When ultraviolet rays are radiated by the discharge, the fluorescent material applied to the inner wall of the glass tube 15 emits visible light when excited by the ultraviolet rays, thereby illuminating the surroundings brightly. Moreover, when visible light permeate | transmits the display part 21 currently formed in the outer periphery of the glass tube 12, the pattern, character, etc. which are displayed on the display part 21 are transmitted clearly. Therefore, the line of sight of the surrounding people can be attracted to the display unit 12 and an excellent advertising effect can be obtained.

  When the fluorescent lamp device 10 is turned on to turn on the fluorescent lamp 1, the motor 50 is also driven, and the rotation of the output shaft 52 is transmitted to the socket 14 via the socket holder 33 on the motor side. The fluorescent lamp 1 is rotated at a low speed (for example, 2 to 5 rpm) in the counterclockwise direction (when characters are written from left to right) in FIG. 1 together with the pair of left and right sockets 14 and socket holders 33 and 33 ′. Let However, the switch of the fluorescent lamp device 10 and the switch of the motor 50 may be provided separately, and may be individually turned on and off.

  When the fluorescent lamp 1 is rotated, the display unit 21 is also rotated, so that a visible part of the display unit 21 and a part that enters the blind spot and disappears are moved every moment. Therefore, if the display portion 21 is viewed until the fluorescent lamp 1 is rotated more than half a turn, the blind spot will be viewed as a blind spot until now, regardless of whether the fluorescent lamp 1 is viewed at the lower, right, or left positions. Thus, the visible angular range in the circumferential direction of the glass tube 15 can be expanded to about 180 ° (conventionally about 140 to 150 °).

  In addition, if the fluorescent lamp 1 rotates by a certain angle, the portion of the display unit 21 that has been blinded until now can be seen, and thus the display unit 21 can be formed larger. Therefore, it is easy to interpret the characters, and the lighting effect and the advertising effect can be further enhanced.

  Further, in the case where the plurality of display portions 21 are formed at a predetermined interval in the longitudinal direction of the glass tube 15, even if there is a display portion that cannot be seen as a blind spot, the fluorescent lamp 1 rotates so that there is an arbitrary If only one display part 21 is viewed, a display part that has not been seen until now can be seen, so it is not necessary to shake the head and move the eyes to the next display part 21, and see It is possible to provide a fluorescent lamp device for advertising that is kind to the user.

  When the fluorescent lamp 1 is turned on, the visible light emitted from the fluorescent lamp 1 increases the temperature of the display unit 21 when passing through the display unit 21. However, since the temperature rise of the display unit 21 is only about 1 to 3 ° C., the display unit 21 is not affected at all. In addition, the brightness of the fluorescent lamp 1 is slightly reduced because part of the visible light is blocked by the display unit 21. However, since the reflection plate 13 having a high reflectance is provided, there is almost no influence on the illuminance.

In addition, although embodiment mentioned above showed the example applied to the single-lamp type fluorescent lamp apparatus 10, this invention is not limited to this at all, Two or more fluorescent lamps 1 were arranged in parallel. The present invention can also be applied to a multi-lamp type fluorescent lamp device. In that case, what is necessary is just to widen the space | interval of the fluorescent lamp 1 so that the display part 21 may not become a blind spot of the adjacent fluorescent lamp 1. FIG.
In the above-described embodiment, the large-diameter shaft portion 33B and the small-diameter shaft portion 33D of the socket holder 33 are pivotally supported directly by the bearing holes 30, 31 of the two mounting plates 26, 27. In order to prevent the lamp 1 from being twisted, it is preferable to support the lamp 1 via a bearing.

  In the present invention, the fluorescent lamp device 10 is applied to an advertising device. However, the present invention is not limited to this. For example, if the display unit 21 has a large number of minute light-transmitting parts that emit light of different colors. It can also be used as a lighting device such as a mirror ball used in a dance hall, stage, studio or the like.
