Description

[Detailed Description of the Invention] [Technical Field] This invention relates to a discharge lamp lighting device.

[Background technology]

As an alternative to incandescent lamps, fluorescent lamps with incandescent lamp bases have been developed. By the way, when lighting a large number of lamps installed in a hallway or the like, it is necessary to branch out the power supply circuit and provide a blinking switch for each lamp, or to remove the lamps. However, the former requires construction work, and the latter is dangerous and aesthetically undesirable.

Therefore, it is conceivable to include a switch in the lighting device built into the fluorescent lamp with an incandescent lamp cap base, and to operate this with a pull string. However, depending on the usage situation such as in a hallway, there is a risk that the appearance will be significantly impaired.

[Purpose of invention]

Therefore, the purpose of this invention is to provide a discharge lamp lighting device that does not require any construction work and can perform thinning lighting without damaging the appearance.

[Disclosure of invention]

This idea has a built-in dimmer device in the lighting device section,
It is characterized in that the light control device is operated by sliding a cover that covers the arc tube with respect to the lighting device section. When the light control device has an on/off operation, the light emitting tube can be turned on and off simply by sliding the cover, so there is no need for construction work when thinning out hallway lights, etc., and the appearance is not damaged. Furthermore, it is extremely convenient and easy to operate because it can be controlled not only on and off but also by dimming.

An embodiment of this invention is shown in FIGS. 1 to 5. In other words, 1 is a screw-in incandescent lamp cap;
2 is a flange, 3 is a high frequency lighting device, 4 is a holder, 5 is a saddle-shaped fluorescent tube, 6 is a cover, and 7 is a switch. The holder 4 is a cylindrical body made of metal with a bottom, and the circumferential surface thereof has circumferential grooves 8 and 9 formed in a corrugated cross-section, and a predetermined number of kerf grooves 10 are formed in the axial direction from the opening edge, so that it cannot be bent in the radial direction. Furthermore, an engagement hole 11 is formed at the edge of the opening. Further, an arc tube fixing cylinder 12 is attached to the outer bottom surface, and an arc tube 5 is attached thereto. As shown in FIG. 5, the high-frequency lighting device 3 includes an inverter circuit section 13 for converting once converted direct current into high frequency, a ballast element 14, and a switch 15.
and a starting circuit section 16, each element of which is mounted on a printed circuit board 17. This printed circuit board 1
7 is fitted inside the holder 2, and its edge is placed on the protrusion 18 on the opposite side of the first circumferential groove 8. At this time, the wiring 19 between the fixed cylinder 12 and the printed circuit board 17 is made. The flange 2 is molded into a cylindrical shape from synthetic resin, etc., and has a plurality of claws 20 integrally molded or bonded inside, and the flange 2 is attached to the holder 4 by fitting the claws 20 into the engagement holes 11 of the holder 4. , touch the printed circuit board 17 with the protruding strip 18 with the tip of the claw 20.
is being pressed. Note that ventilation holes may be provided to improve heat dissipation. The base 1 is wired with a lead wire 21 between the base 1 and the printed circuit board 17, and is fixed to the small cylinder part 22 of the flange 2. The cover 6 has an inner flange 23 on its opening edge, and a part of the inner flange 23 has an operating protrusion 2.
4 are integrally molded. The opening of this cover 6 is located inside the flange 2, and the circumferential groove 8 on the outer peripheral surface of the holder 4,
The operating projection 24 projects inward from the cut groove 10 and faces the handle portion 7a of the switch 7.

In this discharge lamp lighting device, when the cover 6 is slid upward and the inner flange 239 is positioned in the upper circumferential groove 8, the switch 7 is turned on using the operating projection 24. Therefore, the lighting device 3 and the starting device 16
operates, and the arc tube 12 lights up. On the other hand cover 6
Slide the inner brim 23 downward into the lower circumferential groove 8.
, the switch 7 is turned off using the operation protrusion 24. Therefore, the arc tube 5 is turned off.

With such a configuration, this discharge lamp lighting device does not require a pull cord for switch operation, does not require any construction work in thinning lighting, and can have a good appearance. In addition, compared to incandescent lamps, overall initial costs can be expected to be lower due to the higher added value.

6 to 8 show different embodiments. Figure 6 shows a stage dimmer 2 in parallel with the switch 15.
5 are connected, and when the switch 15 is turned on, full lighting is performed, and when the switch 15 is turned off, stepwise dimming is performed. FIG. 7 shows an example in which the ballast element 14' is made variable; instead of the switch, a dimming operation part is provided which is displaced by the slide of the cover 6, thereby changing the degree of engagement of the core of the ballast element 14'. This is to change the inductance value and obtain dimming. In short, the dimming operation section may be any means that allows the constant of the ballast element 14' to be changed by sliding the cover 6. In FIG. 8, the circuit constant of the inverter circuit section 13' is varied to perform dimming, and the cover 6
Change the constant in conjunction with the slide. In the embodiments shown in FIGS. 7 and 8, the movement of the cover 6 may be continuous instead of moving in multiple steps up and down, and the cover 6 may be used to perform continuous light control.

As a disclosed technique, in FIG. 9, a touch switch device 26 is provided in the lighting device 3, the cover 6' is made conductive, and the touch switch device 26 is turned on and off by touching the cover 6'.
The light can be turned off or cyclically dimmed.

[Effect of idea]

As described above, the discharge lamp lighting device of this invention has the advantage that it has a good appearance, can perform thinning lighting without requiring any construction work, and can easily perform dimming operations including on/off operations.
