Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a lighting fixture, and the present invention relates to a lighting fixture that is directly attached to the ceiling and is formed in a hanging type fixture so that direct lighting, indirect lighting, and side lighting can be obtained with one fixture. This is what I did.

[Technical background of the invention and its problems]

With conventional lighting equipment, direct lighting and indirect lighting cannot be obtained unless the direct lighting equipment and the indirect lighting equipment are installed separately. For this reason, in the past, it was necessary to install two types of equipment, which required a lot of effort to install, required a lot of wiring, and was expensive.

A lighting device has been proposed in which the F side of the main body of the device is used as the main lighting section, mainly direct lighting, and the bottom side of this main body is used as indirect or side lighting.

However, when using such lighting equipment as a bedroom light, soft light is required, so the second lighting part is surrounded with a shade made of milky white plastic, etc. It is necessary to have directional lighting.

Therefore, when using a light-blocking shade, it is not possible to increase the distance between the top surface of the fixture body, which forms the lighting part of spear 2, and the ceiling surface for direct ceiling-mounted fixtures, and the light-blocking shade becomes an obstacle when replacing light bulbs. Since the light bulb cannot be easily replaced, the height of the shade cannot be increased, and the indirect lighting effect is reduced.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned drawbacks, and the height of the light-shielding shade is increased to enhance the indirect side lighting effect, and by lowering the shade frame of the shade covering the lighting section 111, the shade can be placed on the shade frame. The shading shade of the lighting section of 2 was also lowered.1.
To provide a lighting fixture in which the lighting section N-2 can be opened and the incandescent light bulb in the lighting section 1t2 can be easily replaced.

[Summary of the invention]

The present invention forms the illumination part of the spear 1 in which a fluorescent lamp is provided mainly for VcW lower illumination on the lower surface of the instrument body, and an incandescent lamp is provided on the upper surface of the main body for mainly indirect side illumination. 2
The illuminating portion of the spear 2 is covered on a shade frame which is attached to the main body so as to be movable up and down and supports the illuminating portion of 1 above with a slight shade to block direct light from the incandescent light bulb. A light-shielding shade is placed with the upper and lower surfaces open, and by pulling the shade frame downward from the main body of the fixture, the shade placed on this shade frame is moved downward from the lighting section of the 2, and the shade of the or 2 is moved downward. The lighting section is opened to the side.
