Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting fixture in which a light bulb-shaped lamp is positioned near the focal point and a reflector is attached.

Generally, in this type of lamp, the relative position of the lamp and reflector is strictly determined during design and light distribution characteristics etc. are calculated, but in order to implement both as a fixture, it is necessary to position each separately. doing. Of course, in some cases, a positioning mechanism is independently provided so that the positions of both are set to desired positions in advance, but the relative positions of both may vary widely due to accumulation of dimensional errors and the like. Therefore, it is difficult to obtain desired light distribution characteristics.

The present invention has been made in view of these points, and an object of the present invention is to obtain a lighting fixture that can accurately determine the relative position of a lamp and a reflector.

An embodiment of the present invention will be described based on the drawings. First, a cylindrical main body case 2 with a downward opening is attached to a ceiling surface 1, and a socket 3 is fixed inside this main body case 2. A connecting part insertion hole (not shown) is formed in this socket 3, and a connecting part of a lamp 4 is detachably attached to this connecting part insertion hole. Further, two presser metal fittings 5 are attached to the lower surface of the socket 3 while being positioned with screws 6. These presser fittings 5 are used as a pair, and a lamp presser 7 that presses down the lamp 4 is connected to the base portion 5a facing each other.
In addition, two reflective plate holders 8 are integrally formed perpendicularly to the lamp holder 7.
These reflector holders 8 are bent into a dogleg shape with a central portion protruding outward.

Therefore, the reflector 10 has an opening 9 in the center.
The opening 9 of this reflecting plate 10 is engaged with the reflecting plate holder 8 to determine its position, and this reflecting plate 10 is held by a cover 11.

In such a configuration, the two presser fittings 5 are accurately positioned with the lamp 4 as the center, and the screws 6 are inserted.
Fix it by. Therefore, the lamp holder 7 holds the lamp 4 evenly. When the reflector 10 is attached in this state, its opening 9 engages with the reflector holder 8, and the four reflector holders 8 hold the reflector 10.
is positioned. At this time, the position of the reflecting plate 10 is centered around the lamp 4 by the holding fitting 5, so the relative position with respect to the lamp 4 is extremely accurate.

In addition, as a specific example of positioning, the reflector 10
If the cover 11 and the cover 11 are separate bodies, as shown in FIG.
1, the opening 9 is the reflector plate holder 8.
The reflector 10 is positioned above the ceiling so that the reflector 10 can be pulled up, and the cover 11 is positioned in the vertical direction by hitting the ceiling surface 1. In either case, the reflecting plate 10 is accurately positioned in the horizontal direction by the reflecting plate presser 8.

According to the present invention, in a socket for holding a lamp as described above, in which a lamp holder is provided, a reflector holder for positioning the reflector is formed integrally with the lamp holder, so that the positioning of the reflector with respect to the lamp is made easier. It can be determined accurately, and as a result, it is possible to obtain the required light distribution characteristics and there is no variation in the characteristics.
