Description

[Detailed description of the invention] [Technical field] This invention relates to an elevating type lighting fixture.

[Background technology]

Conventionally, in order to suppress the temperature rise of the electric lifting device, an air inflow gap 4 has been formed between the lower end opening 2 of the instrument body 1 and the reflecting mirror 3, as shown in FIGS. 1 and 2. However, as shown in the figure, there was a drawback that the reflector 3 was misaligned from the center of the instrument body 1, resulting in a poor appearance. 5 is an electric lifting device.

[Purpose of invention]

Therefore, an object of this invention is to provide an elevating type lighting fixture that prevents misalignment of the reflector when it is stored.

[Disclosure of invention]

This invention is characterized in that, in the above configuration, a plurality of steady rests with entry guides are provided on the outer periphery of the reflector to position the reflector at the center of the instrument body.

An embodiment of this invention is shown in FIGS. 3 to 7. That is, 6 is a cylindrical appliance body, 7 is an electric lifting device provided at the upper end of the appliance, and 8 is a lamp suspended from the wire. stored and the appliance body 6
The dimensions are such that an air inflow gap 10 is formed between the reflector 9 and the substantially paraboloid of revolution reflector 9 of the lamp 8. A guard 11 is attached to the opening of the reflecting mirror 9 by a guard frame 12, and a plurality of steady rest fittings 13 are arranged at equal intervals on the outer periphery of the guard frame 12, that is, on the outer periphery of the opening of the reflecting mirror 9. It is provided by a set screw 14. The steady rest fitting 13 protrudes by a predetermined amount in the radial direction of the reflecting mirror 9 and has an entry guide taper 15 formed at its upper portion.

With this configuration, when the electric lifting device 7 is driven to lower the lamp 8 for cleaning or the like, and then to move the lamp 8 up again, even if the lamp 8 is displaced from the main body 6 of the lamp, it is possible to move the lamp 8 up again as shown in Fig. 7. As shown in the figure, the guide taper 15 of the steady rest metal fitting 13 comes into contact with the lower end of the appliance body 6, guides the lamp 8 to the center of the appliance body 6, and causes it to enter the appliance body 6. Furthermore, within the appliance body 6, each steady rest fitting 13 touches the inner surface of the appliance body 6, so the lamp 8 is positioned at the center of the appliance body 6. In this way, a ring-shaped air flow gap 10 is formed, resulting in a good appearance.

Note that the instrument body and the reflecting mirror may have a rectangular cylindrical shape as long as they are similar in shape.

[Effect of idea]

As described above, according to the elevating type lighting fixture of this invention, since the lighting fixture is always positioned at the center of the fixture body when stored, it has the effect of providing a good appearance.
