Description

[Detailed Description of the Invention] The present invention relates to a starting device for lighting a fluorescent lamp, which generates a high voltage by applying an impact force to a piezoelectric element, and lights a fluorescent lamp using the high voltage.

Embodiments of the present invention will be described below with reference to the drawings.
First, in the figure, 1 is a high voltage generating unit 2 that generates high voltage by applying an impact force to a piezoelectric element (not shown), which is housed in a storage space 1a separated from other parts by a partition wall, and a fluorescent lamp. This is an insulated storage body that houses a preheater (not shown) and a main circuit ON/OFF mechanism as described later. 3 is a pivot pin 1b formed in the storage body 1.
A cam plate rotatably supported by a cam plate and housed in the storage body 1, and an impactor pin 4 protruding from an impactor (not shown) that applies an impact force to the piezoelectric element of the high voltage generation unit 2. It has an impactor pin engagement side 3a that engages, and is an engagement for releasing the engagement between the impactor pin 4 and the engagement step portion 5a provided on the case 5 constituting the high voltage generation unit 2. It has a release side 3b, and further has continuous cam parts 3c and 3d for turning on and off the switch terminals 6 and 7 of the preheater of the fluorescent lamp. The switch terminals 6 and 7 are provided in the container 1 in a normally OFF state, and are electrically connected to the preheater of the fluorescent lamp, respectively. Reference numeral 8 designates a locking spring which is interposed between the cam plate 3 and the storage body 1, is supported by a pivot pin 1b, and is used to always bias the cam plate 3 to the pre-operation state shown in FIG. 9 is a lighting device that is attached to the housing 1 so that a part of it protrudes outside.
The ON button is in contact with the cam plate 3 at its tip. Reference numeral 10 designates an OFF button for turning off the light, which is attached to the storage body 1 so that a part of it protrudes to the outside. A return spring 11 is provided for biasing the device to the pre-operation state shown in FIG. Reference numerals 12 and 13 are switch terminals for the main circuit of the fluorescent lamp provided in the housing 1 in the normally ON state, and these switch terminals 12 and 13 are used for turning off the light.
By pressing the OFF button 10, the lamps are turned off and are electrically connected to the main circuit of each fluorescent lamp. Reference numeral 14 denotes a high voltage terminal for guiding the high voltage generated by the high voltage generating unit 2 to the fluorescent lamp, and its end portion is located on the outer circumferential side of the fluorescent lamp. Further, in the figure, reference numeral 15 denotes a receiving plate which also serves as a receiving and grounding for the piezoelectric element constituting the high voltage generating unit 2, and this receiving plate 15 is in contact with the switch terminal 7. Note that in FIG. 1, a cover attached to the top surface of the storage body 1 is omitted.

Next, its operation will be explained. First, the first
When the lighting ON button 9 is pressed in the state shown in the figure,
The cam plate 3 begins to rotate about the pivot pin 1b as a fulcrum. Then, the switch terminal 6 of the preheating heater rides against the elasticity of the cam portions 3c to 3d of the cam plate 3, contacts the other switch terminal 7, and the preheating heater of the fluorescent lamp is turned on, and preheating of the heater begins. It turns out. At the same time, high voltage generation unit 2
The impactor pin 4 is moved to the engagement step portion 5a by the engagement side 3a of the cam plate 3 against the elasticity of an impact spring (not shown).
The high voltage generating unit 2 stores impulse energy. Here, when the pressing of the ON button 9 for lighting is released, the cam plate 3 returns to the state before activation due to the biasing force of the stiff spring 8, and the switch terminal 6 of the elastic body falls into the cam portion 3c of the cam plate 3, and the switch is activated. Terminals 6 and 7 are separated and the fluorescent lamp heater preheating circuit is turned off. Further, when the lighting ON button 9 is completely returned, the impactor pin 4 is disengaged from the engagement step portion 5a by the disengagement side 3b of the cam plate 3, and the piezoelectric element is activated by the accumulated energy. The shock is applied, and the high voltage generated by the shock is guided to the outer peripheral side of the fluorescent lamp, causing the fluorescent lamp to light up. In addition, when turning off the light, when the OFF button 10 for turning off the light is pressed against the biasing force of the return spring 11, the OFF button 1 is pressed.
The inward protrusion 10a of 0 is an elastic switch terminal 1.
2 and 13 and turn off both.
Therefore, this causes the main circuit to temporarily
It is turned off and the fluorescent lights are turned off. Then,
When the OFF button 10 is released, the return spring 11
The OFF button 10 returns to the state before activation, and the switch terminals 12 and 13 become ON again.
Prepare for the next lighting state.

The present inventors have previously proposed a starting device for lighting a fluorescent lamp of this type in which two high voltage generating units are integrated with the storage body 1. However, in such a configuration, if a malfunction occurs in the high voltage generating unit 2 or other parts, the entire unit becomes unusable, resulting in a large cost loss. Another problem is that the impact sound generated when the impactor of the high voltage generation unit 2 impacts the piezoelectric element during operation resonates and becomes louder because the storage body 1 and the high voltage generation unit section 2 are integrated. It had

However, according to the present invention, even if a defect occurs in each component, since the high voltage generating unit is independently separated, it can be repaired by replacing it, and losses can be kept to a minimum. In addition, by providing a storage gap between the storage space of the storage body and the high voltage generation unit in advance, the impact noise during operation is considerably reduced, and during assembly, the high voltage generation unit can be assembled separately as a preparatory step. This improves assembly efficiency and efficiency. Further, according to the present invention, since the preheating heater switch, main circuit switch, and high voltage generating unit are built into the storage body, it is possible to extremely easily attach the device to a fluorescent lamp stand or the like. In addition, since the ON/OFF of the preheating heater switch and the shock operation of the high voltage generation unit are operated by the same cam plate, the timing of heater preheating ON → heater preheating OFF → high voltage generation can be reliably and easily obtained. This will ensure that the fluorescent lamps are turned on. Furthermore, by using a cam plate, the configuration of the high voltage generating unit can be positioned parallel to the mounting surface of the storage body, reducing the height at the time of installation and, for example, reducing the thickness of the bottom of a fluorescent lamp stand. Its effects and practical value are extremely great, as it can be easily visualized and designed easily.
